摘要
结合煤矿实际运作过程中容易出现的高压防爆开关漏电、消弧线圈接地、数据采集不精确、保护装置在较低范围的运行精度之内动作、频繁误操作等问题,对高压防爆开关及高压防爆开关综合保护的新技术进行论述,通过对比传统技术与新技术确定其优点,为煤矿企业的生产和发展提供一定的参考与借鉴,尽量减少甚至避免安全事故的发生。
Combined with the problems of leakage of high-voltage explosion-proof switch, grounding of arc suppression coil, inaccurate data acquisition, action of protective device within a lower range of operation accuracy, frequent misoperation and so on, the new technology of comprehensive protection of high-voltage explosion-proof switch and high-voltage explosion-proof switch were discussed, and its advantages are determined by comparing traditional technology with new technology. It is hoped that it can provide some reference for the production and development of coal mine enterprises, and minimize or even avoid the occurrence of safety accidents.
