Coal mines and oil wells are large cable users. Due to the harsh environmental conditions of downhole operations, the annual damage of various cables is relatively large. In order to save costs and reduce production costs, each mine and oil well is generally equipped with its own cable maintenance department. However, due to the limitation of the testing equipment, it is often unsatisfactory to repair the cable; the mining cable fault detector is based on the partial discharge method that does not damage the original structure of the cable. It can easily and accurately detect the cable. The damage site, but also has the function of testing after repair, so it is a tool that can be fully trusted in the current cable repair business of coal mines.
Mining cable fault detector features :
1. This equipment consists of a control part (low voltage) and a high voltage rectification, discharge and test department. There is enough room for safety between high and low pressure, high and low pressure, and the housing.
2, in order to ensure the safety of equipment and personnel, high pressure must be operated by a key person before starting.
3. When each flaw detection or cable test, it can ensure that the high pressure starts to increase from the zero position. There is a high and low voltage limit shape, and the step-up or step-down process is controlled by a button, the lifting and lowering voltage rate is stable, and the operation safety is high. Simple.
4, DC withstand voltage test time can be automatically carried out by digital (can also be controlled manually), the test time is accurate and reliable.
5. Leakage current can be measured at any time according to the need of withstand voltage test process.
6, the device has over-current and short circuit protection, there is start warning and over-current protection.
7. On the control panel, there are switches or buttons such as power switch, high-voltage start, high pressure stop, step-up, and step-down, and there are digital voltage time relays for withstand voltage test.
8. There are high-voltage voltage, leakage current and low-voltage total current measurement on the display board, with indicators such as power supply, high voltage, timing, and observation window for ball gap discharge marching.
9, equipped with a dedicated high-pressure discharge, for each test or discharge after the test to ensure safety, the bottom of the box has a grounding sign
