Auxiliary Functions of Underground Pipeline Detector
Auxiliary Functions of Underground Pipeline Detector
Most of the underground pipelines are metal materials, which can induce and transmit electromagnetic waves. With its superior performance and flexible and convenient detection methods, the underground pipeline detector has a large number of users in the fields of electric power, telecommunications, water supply, heat, gas, petroleum, chemical industry, urban public utilities and so on, It has played a positive role in improving the pipeline management level of relevant industries in China. The underground pipeline detector is characterized by multi-functional measurement and simple operation. Stable performance, full digital control, sufficient power, long continuous use time, portable design, suitable for field operation. Under the condition of no excavation, it can not only accurately measure the position of buried pipeline, but also accurately locate the damaged point. Even pipelines with branch pipes or forming a network can be effectively detected. Thus, the pipeline network diagram of * * is drawn, which provides strong support for urban construction and pipeline maintenance. Auxiliary functions of underground pipeline detector 1. Automatic adjustment of receiving gain: automatically adjust the gain of the receiver to make the receiver in an optimized state, avoiding the tedious manual adjustment. 2. Sound function: the tone change sent by the receiver through the horn directly reflects the measured signal size. 3. Pipeline state detection: when the transmitter is in injection mode, first detect the insulation resistance and residual voltage of the pipeline, and then apply the signal to the target pipeline. When the insulation resistance on the pipeline is small (close to short circuit to ground), the transmitter will automatically exit this mode. When the residual voltage is large, the transmitter will give an alarm, and the operator shall immediately stop loading the signal and turn off the transmitter. 4. Battery power detection: real-time detection of battery power. When the power is low to the protection value, an alarm will be sent out and the battery will be shut down automatically. 5. Power saving function: after the transmitter is turned on for about 30 seconds without pressing other keys, and after the receiver is turned on, if other keys are not pressed for about 10 minutes, the machine will shut down automatically to save battery power.
Instructions for Use of Cable Fault Tester
Instructions for Use of Cable Fault Tester
When using the cable fault tester, we should first look at some simple waveform diagrams to analyze different cable faults, and then find out the fault points through the corresponding methods. The following is our simple analysis and description. 1. Test the low resistance grounding, short circuit and open circuit faults of the cable with the low voltage pulse method. A. no other auxiliary equipment is needed at this time. A clip wire is directly connected to the input and output interface of the cable fault location host. Clamp the red clamp of the clamp wire on the faulty phase core wire of the faulty cable, and the Black clamp on the sheath ground wire of the cable. B. Start the power switch of the instrument, the screen saver picture will appear on the screen, and click to enter the interface automatically. At this time, the default state of the instrument is "low voltage pulse method". The use method shall be selected according to the type and length of the tested cable on site and the fault nature preliminarily judged. When it is set to "low voltage pulse method", wave velocity measurement can also be carried out on this interface, and historical files can be opened to view previous test results. C. After setting the equipment parameters, click the "sampling" button, and the instrument will automatically send out test pulses. This interface will display the (open circuit) full-length waveform of the cable (as shown in Figure 5) or the low resistance grounding (short circuit) fault waveform (as shown in Figure 6). If the waveform is not good, the operator shall adjust the "median" and "amplitude" and observe the collected echo until the operator thinks that the amplitude and position of the echo are suitable for analysis and positioning. Basic information such as instrument parameter setting is also displayed at the bottom of the screen. During operation, pay attention to the operation status at the bottom of the screen. D. Waveform positioning reading distance. It is easy to judge the distance of low-voltage pulse, as long as the cursor is positioned to the starting point of transmitted and reflected waves respectively. E. When "saving", the test results need to be retained or reserved for comparison. The "saving" function in the instrument should be used to save the measured waveform in the instrument database. If the tester thinks it is necessary to save the test results, he can click "save" and operate according to the prompt in the submenu. 2. The high resistance leakage fault (including high resistance flashover fault) of the cable is tested by the impact high voltage flashover method. The instrument can test the high resistance leakage fault of the cable by the impact high voltage flashover method. Impulse high voltage flashover method is a popular traditional detection method in China. Many users are used to this method. The external circuit is relatively simple, but the waveform analysis is more difficult. Only on the basis of a large number of tests and some experience can we master it skillfully, but it is still an effective test method. Connect the current sampler attached to the instrument with the host with the signal wire and place it next to the grounding wire between the cable and the high-voltage equipment. As long as the output voltage of the impulse high voltage generator is high enough, the fault point will be broken down under the impulse of this impulse high voltage, and the radio wave reflection will be generated in the cable. The current sampler transmits the induced reflected wave obtained from the current signal on the ground wire through magnetic coupling to the cable fault location host for a / D sampling and data processing, and displays the collected waveform on the screen for fault distance analysis. After the cable type and sampling frequency are determined, you can click the "sampling" button to wait for sampling. Once the high-voltage generator has impulse high-voltage flashover, the instrument will automatically carry out data acquisition and waveform display. The red waveform at the top of the screen is the waveform after local amplification, and the blue waveform at the bottom is the full picture of the test waveform. When the ideal waveform is collected, the "waveform scaling" and displacement and moving cursor can be operated to calibrate the fault distance. The operation method is consistent with the low-voltage pulse method. 3. Wave velocity measurement cables produced by different manufacturers, although the models are the same, the differences in process and medium formula will lead to the differences in radio wave propagation velocity. If the average wave propagation speed given by the instrument is directly used, it will cause a certain test error. In order to test the fault distance more accurately, it is often necessary to recheck (test) the radio wave propagation speed of the cable.

Location Method of High Resistance Damage in Power Cable Line
Location Method of High Resistance Damage in Power Cable Line
In order to preliminarily determine the high resistance damage in power cable lines, the combination method of high voltage reflection method is usually used: pulse arc method and vibration discharge method. In this paper, we will consider the main ideas embedded in these methods and how they work. In addition, we will discuss the equipment to implement these two methods. 1、 Pulse arc method (ARM) is used to determine high resistance damage. The main idea of pulse arc method is to use a special high-voltage pulse generator. For example, in the arc cable generator of power cable, oil first creates conditions for the generation of high resistance defects and causes short-term arc (breakdown). According to the magnitude of the leakage current and the power of the current source, use one of two ways for the generator to act on the cable line: 1. Smoothly charge KL's own capacity (cable) from the generator current source until breakdown occurs. This method can be used if the leakage is so small that the power supply of the high voltage pulse generator is sufficient to charge before breakdown. For defects with serious leakage, this method is not applicable. 2. Charge the built-in capacitor of the generator to the required voltage (not exceeding the test standard), and then discharge the cable instantaneously. In this case, the high-voltage pulse propagates in the cable, which will lead to failure when it reaches the location of the defect. This method can be used to search for defects on cable lines with serious leakage. In both cases, the use of inductors integrated in the generator will delay the arc combustion time. The current pulse from the breakdown (propagating from the defect to the input of the generator) triggers a synchronous circuit that starts the low-voltage sounding through the cable fault locator (also known as the cable fault tester). The physical characteristics of the arc have low resistance, and the detection pulse of the cable fault locator is also reflected from medium and low impedance defects (short circuit). Advantages of pulsed arc method the pulsed arc method (ARM) for determining high resistance damage has several advantages. This is a non-destructive method, because unlike combustion, the impact of high voltage on the cable is short. Unlike combustion, this method will not reduce the cable parameters as a whole, and will not cause new damage where the insulation resistance is still within the normal range. Arm is actually a high-precision method, because the measurement is actually carried out by pulse method. 2、 The vibration discharge method (ice / attenuation) should deal with high resistance damage. The vibration discharge method is used to find damage on a long cable line, or when the pulse damping of the underground cable fault locator is too large for some reason to apply the pulse arc method. The vibratory discharge method allows you to locate most faults that can be detected using the pulsed arc method, but usually reduces accuracy. It should be noted here that the function of the cable is not displayed when operating by the vibration discharge method. Current oscillation discharge method (current fluctuation method, ice) when the wave current method is used, the oscillation circuit is formed by the system: capacitor on the source side - Cable - low transition resistance (or arc) at the defective part. When the method of vibration discharge through current is used, according to the leakage current value and the power of the current source, here, as with the pulse arc method, one of the two methods of exposing the cable to the generator is used: 1. Smoothly charge the CL capacitor from the generator current source until breakdown occurs. This method can be used if the leakage is so small that the power of the current source is sufficient to charge before breakdown. For defects with serious leakage, this method is not applicable. 2. Charge the built-in capacitor of the generator to the required voltage (not exceeding the test standard), and then discharge the cable instantaneously. In this case, the high-voltage pulse propagates in the and reaches the defective part, resulting in breakdown or large discharge current. This method can be used to search for serious defects. The discharge current pulse returned to the source will charge its capacitor, which in turn. The wave reaching the defect may cause a discharge in it again (in this case, its polarity will change), or if a second discharge does not occur, it will reflect with the same polarity and repeat the process again until all the energy of the initial pulse disappears. These vibrations are displayed on the screen of the cable fault locator connected to the cable through the inductive sensor.
Application Field of Cable Fault Locator
Application Field of Cable Fault Locator
The application field of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.
