Principle of Buried Cable Fault Tester
Principle of Buried Cable Fault Tester
Compared with buried wires, buried wires and cables have been used in China for decades. The buried cable fault tester has developed from resistor bridge, capacitor bridge detection and standing wave detection at the beginning of Zui to flashover detection. The development trend of instruments and equipment has experienced the flash detector for general oscilloscope tube display information and the flash detector for storing oscilloscope tube display information. Up to now, intelligent instruments and equipment have been developed, produced and manufactured. The buried cable fault tester adopts large-scale integrated circuit chip, electronic computer solution technology, LCD display technology and other new technology applications, new technologies and new processes. After the wire and cable testing equipment is improved, the common faults of ground buried double eyelid are detected, which has good practical effect and high efficiency. After many practical activities, the common faults of a buried cable double eyelid are generally detected. The buried cable fault tester has a high success rate within 30 minutes from the beginning to the end. Principle of buried cable fault tester 1. The buried cable fault tester uses a unique acoustic frequency vibration sensor and low-noise special components as external components, which further improves the sensitivity of instrument and equipment designation and relative path detection. In terms of signal analysis technology, the distance between the common fault points of digital display information and the sensor technology camera greatly eliminates the one sidedness of designation. 2. When detecting the fault of buried cable, the common fault cable in the empty frame in the cable trench. In the past, the vibration sound of the whole cable makes all the designated instruments helpless, and it is impossible to judge the specific address of the closed common fault. Now, if the controller camera of the instrument touches the common fault cable or the nearby cable line, the information can be directly displayed, and the common fault spacing and orientation can be quickly identified without effort. 3. Based on the basic theory of DC response cancellation and high DC notch technology, the buried cable fault tester greatly improves the suppression and anti-interference of 50Hz DC data signal in the natural environment of strong power frequency electric field, and reduces the specified blind spot. In terms of the function of instruments and equipment, the acousto-electric technology is used to accept the photoelectric technology, which reasonably gets rid of the difficult problem caused by the impact of natural environmental noise on the designated site. In particular, the large digital display information of common fault spacing eliminates the operator's specific analysis of complex wave type, and replaces the rough distance measurement function of flash detector to a considerable extent. For the common fault cable hundreds of meters long, the designation can be carried out without rough measurement, which is truly efficient, rapid and accurate. Using 15z amplitude modulation radio wave and amplitude detection technology for relative path detection and deep measurement of cable laying, the influence of TV line frequency on the designated instrument in the original equal amplitude 15z video signal is prevented. 4. The fault detection of buried cable is very simple in practical operation. You can turn on the main power switch without shifting gears and selecting functions. Compact structure, exquisite and modular design, which is conducive to on-board maintenance and complete functions. Buried cables are widely used in recent years. Therefore, there are many ways of buried cable fault tester, which are not well understood by rural welders and repair and test workers. There are common faults in the ground buried line. If there are no excellent instruments and equipment and good test standards, the common faults can not be removed within the service guarantee period of the power supply system company, which not only delays time and wastes human resources. And affect normal life and industrial production.

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.
Principle and Application of Cable Oscillation Wave Test
Principle and Application of Cable Oscillation Wave Test
1、 Principle of cable oscillation wave test through cable oscillation wave test can not only diagnose the overall insulation of cable, but also test partial discharge and locate defects. The principle is LCR damping oscillation principle. On the basis of completing the cable pressurization, a damping oscillation voltage wave is formed through the built-in high-voltage reactor, high-voltage solid-state switch and the test cable. A sinusoidal voltage wave similar to the power frequency is applied to the test cable to excite the partial discharge signal at the potential defect of the cable. Based on the pulse current method, the partial discharge signal is detected with high sensitivity, and the detection, acquisition and upload of partial discharge signal are completed with high-speed data acquisition equipment. The single test process is about one minute, with high test efficiency and no damage to the tested cable. On the basis of obtaining the partial discharge data, the data analysis software automatically completes the cluster analysis and traveling wave positioning, which is convenient for users to comprehensively evaluate the cable state. 2、 Purpose: the cable oscillation wave test standard passes the field test to check the insulation condition and internal partial discharge condition of the cable without damaging the insulation of the cable itself, so as to evaluate the cable insulation. The high voltage unit of cable oscillation wave test can generate oscillation wave high voltage signal, and the high voltage generator can generate any high voltage of 0-30kv; For the partial discharge test device with no blind area from the partial discharge signal, there is no blind area, and it can detect the cable below 250m for partial discharge test; One laptop can be used for control; External safety control units such as operation software (Chinese / German / English version); Analysis software (Chinese / German / English version); A 7.5m high-voltage connecting line without partial discharge, with anti falling off safety design; The partial discharge under system voltage is less than 1pc III. cable oscillation wave test case analysis through the above understanding, let's talk about examples below, so that you can better understand its actual field use. Firstly, connect the test line according to the instructions, and then turn on the power supply. The waveform diagram during the test is as follows: through a waveform analysis, we found a damaged gap in the outer sheath at about 132M in the field survey, which is the cable insulation damage caused by external construction force. After disassembly, the main insulation is damaged
