In the past years, people think that there are many different points in high-voltage cables and low-voltage cables. The high voltage cable failure is mainly based on general operation fault, and most of them are frequent failures, and high-resistance is often faulty. In addition to leakage and flashing, there are many different points in high-voltage cables and low-voltage cables. The high-voltage cable failure is mainly based on general operation faults, and most of them are frequently faults. The high-impedance is often faulty and the spills and the flashing have two major types. Today, we mainly discuss this problem, and let everyone have a simple understanding of cable fault detection methods. The cable has the following features during the specific application: 1. The blindness of the layout is relatively large, and the relative route is not very clear.
2. When it is embedded, it is not embedded after the high-voltage cable, which is buried, buried deep, and is easily destroyed by external force. 3, the cable line is generally short, dozens of meters to 500 meters, unlike high voltage wires, usually five hundred meters to a few kilometers. 4
5. On the common fault point of most cables, there is often a very obvious flash failure. It is very rare to leave a trace in a common point of failure on the wall wall. 6, the required load changes very large, and usually two colors are unbalanced, very prone to burns, and common faults caused.
Considering the top characteristics of the cable and the specific recommendations of many users and the comprehensive consideration of the specific application of each region, scientific research staff successfully developed the DW cable fault test mobile phone positioning system: System software includes two parts: range finder and probe. The system software of the rangefinder is a fully intelligent system, a personalized design, which can fully automatically detect the cable fault point, no artificial analysis of common fault waveforms, give a common fault point pitch and common fault characteristics. Battery charging power supply, facilitates field work, small size, light weight, easy to use, no need to assist machine equipment.
The cable fault tester is an instrumentation device for precise positioning of the relative laying path of the straight buried cable, the position of the depth, and common fault point positions. Because the magnetic force effect of the current is selected, it is designed to design a cable common faulty mobile phone positioning system for the basic principles of the step voltage. It considers all the test standards for cable failure. Relative to“Flash memory”For the basic principles cable fault detector, this detection system software has many advantages: 1, multiple test standards are set to each other, to identify the results to clarify the uniqueness of common fault points.
2, small body shape, lighter weight, actually operate, no auxiliary mechanical equipment. 3. Select the charging battery power supply system, suitable for field work, no ignition charge and discharge. 4, the relative path search of the cable (can be within 30 cm), deep detection, common fault point precise positioning, high efficiency.
5. For common fault points, the instrument equipment can visually display information without having to perform waveform analysis. 6, not harmful by ground conditions, such as: floor tile, road green, concrete floor, etc. 7. Check the safety of the site, will not cause danger to the inspectors, and will not cause secondary destruction to the cable line.
8, the product quality is excellent, and the general customer can accept. The relevant content of cable fault detection will introduce it to you. Did you know? I want to learn more about knowledge, remember to continue to pay attention to Xiaobian! .
