摘要
介绍了煤矿供电系统中,一种应用于井下高压防爆开关的基于"时序鉴别"原理的高压漏电保护装置的硬件设计;并通过现场试验分析了该装置的实用性;为煤矿高压开关漏电保护,找到一种行之有效的方法。
The hardware design of a high voltage leakage protection device was introduced based on the "timing discrimination" principle, it could be applied in a high voltage explosion - proof switch in the power supply system of coal mine. Through the field tests, the usefulness of this device was analyzed, which provided an effective method for the leakage protection of coal mine high voltage switch.
