What are the structural characteristics of the mine cable fault tester? Mining cable fault tester is specially designed for all kinds of mining cables below 6kV to conduct flaw detection on the ground, including short circuit and open circuit, and AC and DC withstand voltage experiments are carried out after the cable is repaired and before the new cable goes down the mine. What are the structural characteristics? The mine cable fault tester is specially used for all kinds of mine cables below 6kV to conduct flaw detection on the ground, including short circuit and open circuit, and for AC and DC withstand voltage test and leakage current test after the cable is repaired and before the new cable goes down the mine. It is a necessary comprehensive equipment for cable repair and cable testing in mines, which meets the requirements of "Coal Mine Electrical Experiment Regulations" and is highly practical. It is based on the partial discharge method that does not damage the original structure of the cable. It can easily and accurately detect the damaged part of the cable, and it also has the function of testing after repair. Therefore, it is the current coal mine cable repair business. A tool you can fully rely on.

Cable fault tester Coal mines are major users of cables. Due to the harsh underground operating conditions, the annual loss of various cables is relatively large. In order to save expenses and reduce production costs, each mine generally has its own cable maintenance team. However, due to the limitations of testing equipment and technology, when repairing cables such as fully mechanized mining, the flaw detection test is often unsatisfactory, and most of them use the forced breakdown method that damages the cable insulation. Structural features of the mine cable fault tester: 1. On the control panel, there are switches or buttons for power switch, high voltage start, high voltage stop, boost, buck, etc. There are digital time timing relays for withstand voltage test, etc.

2. There are high-voltage voltage, leakage current and low-voltage total current measurement meters on the display board, and there are indicator lights for power supply, high voltage, timing, etc., as well as an observation window for spherical gap discharge. 3. Every time a flaw is detected or a cable is tested, it can ensure that the high voltage starts to rise slowly from the zero position, and has the shape of high and low voltage limit. Simple. 4. The mine cable fault detector is composed of the control part (low voltage) and the high voltage rectification, discharge and test parts.

Sufficient safety space is reserved between high and low pressure, between high and low pressure and the shell. 5. The mine cable fault detector has over-current and short-circuit protection, as well as start-up pre-warning and over-current protection. 6. The mine cable fault detector is equipped with a special high-voltage discharge rod for discharge after each flaw detection or test to ensure safety. There is a grounding mark at the bottom of the box.

7. The leakage current can be measured at any time according to the needs of the withstand voltage test process. 8. In order to ensure the safety of the instrument and personnel, it must be operated by a special person with a key before starting the high voltage. 9. The DC withstand voltage test time can be automatically carried out after digital (or manually controlled), and the test time is accurate and reliable.
