The Evolution of the Handheld Laser Measuring Device in China
The Evolution of the Handheld Laser Measuring Device in China
The Great Wall of China, the Taj Mahal, the Roman Colosseum and the pyramids are just some of the largest and small gauges in the world in critical buildings. The development and mastery of these tools has been crucial to the evolution of the human species. Laser pointers are also used in robotics, for example, laser guidance guides a robot into a target position using a laser beam. Green laser pointers are used for similar purposes in daylight and over long distances. Another common use of lasers in entertainment is the special effects used in laser shows. Clubs, parties and outdoor concerts often use high-power lasers as security for the spectacle. For example, construction companies use high-quality laser pointers to increase the accuracy of displaying certain distances when working on large-scale projects. In astronomy, laser pointers can be mounted on a telescope to align the telescope at certain star locations. Green laser pointers are also used by astronomers for star parties or lectures on astronomy. Laser rangefinders have built-in processing capabilities that allow them to triangulate, calculate and measure distances, as well as calculate area and volume. They are accurate enough to measure long distances and display fast measurement results, compared to traditional bands used for measurement applications. With the various functions that digital handheld meters offer, the demand for these devices via tape increases. A major factor in the growth of hand-held laser rangefinders is the growing construction sector. Noyafa is committed to scientific and technological applications of laser detection. The growing demand for digital measuring instruments for precise measurements and the resulting growing demand for hand lasers and distance meters in the construction industry is a key factor in the growth of the market for hand lasers and distance meters worldwide. Measuring tools continue to evolve with technological advances such as lasers. With the development of mass production of integrated circuits (IC), the measuring tapes have become digital. This is different from 100-foot measuring tapes, which are made of fabric and used to mark the exterior dimensions of large buildings.

The Differences Between Cable Recognizer and Other Power Fault Detection Equipment Are Analyzed
The Differences Between Cable Recognizer and Other Power Fault Detection Equipment Are Analyzed
Cable recognizer and cable fault tester have been introduced in previous articles. I believe you have a simple understanding of the functions and characteristics of these two devices. Some netizens have consulted Xiaobian before. What is the difference between the two devices? In order to meet everyone's thirst for knowledge, Xiaobian will give you a brief introduction today. The difference between cable identification instrument and cable fault tester: first of all, it should be distinguished. Cable identification instrument is the function of identifying cable, and cable fault tester is the function of finding path. It is basically the same in principle, and there are great differences in function and use method. For example, the measurement of cable fault tester must be in power failure state, while cable identification instrument can be live measurement; The cable identification instrument can accurately identify a cable, while the cable fault tester can only be an accurate path direction. Today, let's talk about the technical principle of the cable identification instrument and the use method of the cable identification instrument. 1、 Technical principle of cable identification instrument: firstly, the identified cable needs to be grounded at the far end. The generator feeds periodic unipolar voltage pulses into the cable to be identified, and the outgoing current only passes through this cable. All other adjacent cables flow return current, but their polarity is opposite. In addition to the difference in current direction, the current amplitude is also an identification feature, The outgoing current only passes through one cable, while the return current can pass through several cables, which means that the current flowing out is greater than the return current flowing through other cables. The receiver detects the direction and size of the current flowing through the cable, and the generated magnetic field induces a voltage in the sensor coil. The voltage polarity is determined by the current direction and the direction of the sensor coil, The voltage induced in the sensor coil displays the measurement result in the meter. 2、 Differences between cable identification instrument and cable fault tester 1. Set the test circuit. In order to ensure the normal use of the instrument, pay attention to setting the test circuit. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. 2. When the instrument calibrates the receiver, use the sensor to clamp the cable (close to the generator) at the beginning, the arrow points to the current direction, that is, to the far end of the cable, and then use the same receiving sensitivity for detection at the place to be detected. Use the sensor to clamp each cable once, and the arrow direction points to the far end of the cable. When the cable to be identified is clamped, The reading on the receiver meter is 4-6 grids and deflects to the right. All other cables either have no reading, or the reading is very small and the current direction is opposite, that is, deflects to the left. The cable identification instrument is only the function of identifying the cable. If it is necessary to operate the cable, the identified cable must be pricked and grounded with the cable pricker according to the power test standard. Do not use manual sawing before grounding.
What Are the Common Faults and Discrimination Methods of Cable Fault Tester
What Are the Common Faults and Discrimination Methods of Cable Fault Tester
1、 Cable fault type power cable fault is mainly due to mechanical damage, insulation aging, low construction quality, overvoltage, etc. The commonly used cables are cross-linked ethylene, non dripping oil type, oil immersed paper type, polyvinyl chloride and unknown type. According to the nature of cable fault, they can be divided into low resistance grounding or short circuit fault, high resistance grounding or short circuit fault, disconnection fault, disconnection and grounding fault and flashover fault. 2、 Firstly, we need a megger to measure the insulation resistance of each phase, and judge the fault type according to different insulation resistance values. 1. When we measure that the insulation resistance of the cable to the ground is lower than 100k Ω, it is a low resistance grounding fault. 2. When we measure that the insulation resistance of the cable to the ground deviates from the normal value or is higher than 100k Ω, it is a high-voltage cable fault. 3. When the ground resistance of the measuring cable is high or normal, conduct multiple tests on the conductor to check whether there is a wire break. If there is a wire break fault. 4. When the conductor of each core or multiple cores of the measuring cable is discontinuous, and then after multiple core to ground measurement, judge which type of the above three faults. 5. Flashover fault basically occurs in preventive voltage withstand test, cable terminal and middle joint. Sometimes flashover occurs many times, but the interval is a few seconds or minutes. 3、 Cable fault tester to find out cable fault methods: 1. With high-voltage equipment, it has the traditional impact high-voltage flashover method and low-voltage pulse method. 2. 2. Any high resistance fault presents simple waveform characteristics similar to low voltage pulse short circuit fault, which is very easy to interpret. 3. The cable fault tester finds the fault point through four main parts: cable fault location host, locator, Pathfinder and high-voltage signal generator.

System Composition of Intelligent Cable Fault Tester
Intelligent cable fault tester is an important tool for maintaining various cables. It adopts a variety of fault detection methods, applies contemporary advanced electronic technology achievements and devices, adopts computer technology and special electronic technology, and combines the long-term successful experience in developing cable tester. It is a high-tech, intelligent and fully functional product. The intelligent cable fault tester is composed of three parts, which is used for the test of various faults of power cables, the search of cable path and cable burial depth, the daily maintenance and management of cable archives, as well as the fault test of railway and airport signal control cables and street lamp cables. Cable fault finding is generally divided into four steps: fault nature diagnosis, fault location, path detection and fault location. The methods of fault location mainly include: first, the bridge method, mainly including the traditional DC bridge method, voltage drop comparison method and DC resistance method; The second is the low-voltage pulse method, also known as the radar method, which is to input the low-voltage pulse signal into the cable through the instrument at one end of the cable. When the fault point with mismatched wave impedance is encountered, the pulse signal will be reflected and returned to the measuring instrument. This method has the advantages of simple operation and high test accuracy. It is mainly used to test line breaking and low resistance faults, but it can not test high resistance faults and flashover faults; The third is the pulse voltage method, which needs to apply DC high voltage signal to the faulty cable; Fourth, pulse current method, which needs to apply DC high voltage signal to the faulty cable; The fifth is the secondary pulse method. System composition of intelligent cable fault tester: 1. Host of cable fault tester 2. Cable path and fault locator 3. Cable fault integrated high voltage generator 4. Cable identifier 5. High voltage cable safety pricker 6. High voltage equipment: current sampler, cable fault integrated high voltage generator, pulse capacitor, complete set of special test line, etc.
Tips to Clean Stainless Non Contact Voltage Tester
Tips to Clean Stainless Non Contact Voltage Tester
You do not want to use hard abrasives or chemicals that leave a dirty film or stain on the surface. Avoid abrasives and abrasive powders such as steel wool, as these can scratch and damage the finished material. Avoid using abrasive powder or steel wool with bleach or ammonia, which can damage the texture and shine of the stainless steel surface.Some popular cleaning products can damage the surface of stainless steel, and clear water can leave marks and stains if not used properly. Do not use gravelly, dirty or hard water as it can leave stains and brownish stains. Choose a cleaner that is designed for use with stainless steel and start with a gentle cleaner that you can use with a little elbow grease to clean the surface.A soft cloth, moistened with warm water, is sufficient for general cleaning. Use a grease cleaner available at your local hardware store or grocery store and follow the manufacturer's instructions. Apply a non-abrasive cleanser like a soft scrub with a damp sponge and rub off the cleaner.Most filters can be placed in the dishwasher at low heat for a short cycle with a phosphate-free detergent. Of course, like other items in a dishwasher, filters can collect food residues. Filters can be washed by hand in warm water with a phosphate-free detergent such as Dawn.A light paste of baking soda and water acts as a light abrasive to neutralize the remaining acid. Apply the paste to the clean surface with a soft sponge and rub off any haze that might affect the surface or pattern towards the existing surface.Clouds can lead to a stain that can be cleaned so that when removed it is too thin to spread a blurry film. Non-powder coated metal parts, including hardware, are susceptible to corrosion and discoloration. It is recommended to pay special attention to these components during cleaning.There are numerous non-abrasive cleaners and polishes specifically designed for the use of stainless steel. Utilising something like Bon-Ami (r) Cleaner for non-coated or coated surfaces can help minimize corrosion and maintain the appearance of non-coated metal lift components, including hardware. My personal favorite for stainless steel cleaning is the 3M stainless steel cleaner (available on Amazon), but there are several other recommended brands available, including Bar Keeper Friends (available on Amazon ), Cerama Bryte (available on Amazon ), Sprayway (also available on Amazon) and Weiman (available on Amazon ).To make things easier, we have our own brand of water-based stainless steel cleaners that clean gloss, scratches and water stains while retaining the original surface of the stainless steel. If in doubt, test your stainless steel by cleaning the surfaces hidden on the back and sides and then moving the clean stainless steel into visible areas, including the front of the appliance and the tops of the kitchen counters. If you hesitate with stainless steels other than household appliances, there are finishing options such as Classic White, Black, Matte Black and Black Stainless Steel.For cleaning you can use alcohol or other household cleaners such as formula 409, lysol (r) or pine sol (r). Stainless steel is an iron-based alloy that contains chromium that combines with oxygen to form an invisible protective film on the surface, but this film is not stainless. Follow the above procedures to inspect and maintain sealed steel rails and ladders.Non-contact voltage testers are a safe method to ensure that the wires are not touched by current. They light up and make no noise when they come near hot, current-carrying wires, especially those covered with plastic insulation. If you hear continuous chirping or see a series of flashes, this confirms that the tester has detected voltage.On Android, make sure Bluetooth is turned on in your phone's settings and start the tying process on Android. To do this on iOS, your mobile device under the hood must be connected via Bluetooth. If you do not find a device named Zephyr XXX under the hood on iOS during this process, make sure the device is in mating mode.The newest and best commercial cleaners are not the best, but stainless steel cleaners are the safest. Try out some DIY cleaners on your appliances to see for yourself and remember to test the stainless steel cleaner on site before using it.

How to Carry Out Fault Location of High Voltage Cable
How to Carry Out Fault Location of High Voltage Cable
The speed of China's economic development is obvious to all. The country's economic development has driven the development of all walks of life, and all kinds of construction work has been strengthened. The construction scale of national power grid is expanding. Although China has also popularized and applied multi-channel high-voltage cable technology, its structure is becoming more and more complex, resulting in multi-channel failure of high-voltage cables. Next, we discuss the problem of fault location of high voltage cable. High voltage power transmission lines have been affected by environmental changes in recent years. The insulation layer of cables is damp due to rainy weather and ponding, the overall overheating in the process of cable use, and the high voltage of cables will not only affect people's power consumption experience, but also cause irreparable loss of economic benefits to relevant power consumption enterprises. How to accurately locate and quickly remedy the fault of multi branch high-voltage transmission line cable has become the focus of power supply departments and power companies. 1、 The construction and analysis of cable simulation model great changes have taken place in the current natural environment, and the natural wear of cable lines is becoming more and more serious in the harsh natural environment. Therefore, the stable and continuous operation of the cable requires the cable protective layer to protect the cable, and the cable protective layer usually plays a key role in protecting the cable. We need to consider the cable, so we should select the power supply equipment matching the cable in the test. However, we should note that when setting the data of the power supply, we need to select the conventional settings of the circuit and resistance, and do not exceed the range borne by the cable. 2、 Simulation and analysis of two-t lines the application of two-t lines is an innovative technology for today's multi branch cable erection, but no country can widely use this technology. We can evaluate the design idea, design scheme, design results and the effect after being put into use in a small scale. We can improve the cable technology in some large cities and areas with complete urban power grid construction. We can transform the original main power supply line into a power supply line of two t lines. If we use this technology, we can increase the investment of the corresponding part in the project and complete it as soon as possible. 3、 Firstly, when the fault location is in Section D, set the fault point in phase a of Section D and carry out the simulation process test. Based on the grounding wire at the beginning of a section, it is concluded that after a problem occurs, the current has a continuous transient process. Then, the metal sheath current that is slowly stable and connected to the fault is large, and the high amplitude reaches 5A. At the same time, the large amplitude of the non fault phase also reaches 1 A. there is no great difference between the current wave detected by this stage and the normal grounding wire. The main route of fault location of high-voltage cable and the route of fault section are cross connected, and the attenuation amplitude of high-frequency voltage will appear after fault. If the insulation layer in the cable breaks down, we can measure the grounding current in different sections and the attenuation amplitude of high-frequency voltage, and analyze the location of cable accident from the measured data.
