In recent years, with the continuous development of society, computer technology and electronic technology have also developed more and more prosperous. Cable fault identification instrument We have a simple introduction in the previous article, here is not described here. Today, Xiaobian continues to bring you attention to electricity in recent years. With the continuous development of society, computer technology and electronic technology have also developed more and more prosperous.
Cable fault identification instrument We have a simple introduction in the previous article, here is not described here. Today, Xiaobian continues to bring you related knowledge of cable fault tester, and interested friends don't miss it. In recent years, with the development of electronic technology and computer technology, the cable fault tester has a more rich and reliability and life.
Today, its development has shown a new highlight. I. Adding new type of smart module in cable fault test: new sensors such as fiber optic sensors, polymer sensors, and biosensors continue to appear, and will achieve faster development. Second, the emergence of the new cable fault test fieldbus structure: expands the self-diagnosis function of the cable fault test instrument, and easy to maintain, the connection of the cable test system is more reliable and easier, so the installation cost is greatly reduced, and the control scale varies.
Third, electronic cable test system function integration: more closely combined with computers, power electronic devices, and strong control control, continuous control and intermittent control. Cable fault testers are a comprehensive set of facilities. Used in electric cable opening, short circuit, grounding, low-impedance, high resistance flashing and high-resistance vented faults, and the opening of coaxial communication cables and municipal cables, short circuit failures are very accurate test.
You can also test cable channels, depth, and radio wave speed, check the length of the cable, and establish cable files to usually protect management. Cable fault tester investigating the method of troubleshooting: 2, insulation resistance data analysis, connector position If the customer's field data is unclear, it can only be referred to the reference.
3, determine the fault point range and fault point, use high pressure flushing test process: After the pulse method is completed, use the flushing method to test, according to the fault insulation, first use of a lower insulation resistance a phase test, capacitor 2 microscopic method 20kV, impact voltage 15kv, test. 4, high pressure flushing test waveform is a di-discharge waveform, breakdown waveform. Then according to the flake test, the fault point is difficult to break through the discharge, but the second breakdown waveform can determine the distance, even if the rough test is completed.
5, followed by the fault point precision point. The test site is within the roughness distance, it is exactly the catering yard, and the fixed-point test environment is relatively poor. The fixed point can only be carried out on the pile of coal, by careful work, through the acoustic synchronous fixed-point instrument, it is determined by the acoustic synchronization designation.
6, the voltage test of the cable, with a series resonant to the compressible cable, the pressure time is not less than one hour. In the specified time, smoke, extravasation, Flash, flash arc, etc., it indicates that insulation is defective. If the boosting process is not different, it indicates that the pressure resistance is good, it can be used normally.
Today's content, let's talk about it, want to know more cable fault tester, please continue to pay attention to Xiaobian.
