煤矿供电系统漏电保护技术的应用与发展

Application and Development of Leakage Protection Technology in Coal Mine Power Supply System

由于井下环境恶劣,井下时常发生漏电故障,作为煤矿供电系统三大保护之一的漏电保护对整个煤矿正常生产与人身安全有着的重要意义,根据《煤矿安全规程》要求漏电电流不得超过30m A·s,所以对于井下漏电保护要求具有足够的可靠性和相应的灵敏性来维持矿井供电系统的安全稳定。随着数字化矿山的发展趋势,漏电保护装置也由传统的模拟器件向着由微机监控和处理信息的漏电保护综合系统发展,本文简要介绍了目前漏电保护技术目前应用与发展状况。只有研究好了煤矿漏电保护才能为煤矿安全生产保驾护航。

Due to the harsh conditions in the mine, mine frequent leakage fault, as the leakage protection in mine power supply system to protect one of the three of the entire coal mine normal production and personal safety has important meaning. According to the 〈 Coal Mine Safety Regulations〉requirements leakage current shall not exceed 30mA-s, so for the underground leakage protection requirements with enough reliability and the corresponding sensitivity to maintain the safety and stability of power supply system of coal mine. With the development trend of the digital mine, leakage protection device also by the traditional simulator towards the development of integrated system by microcomputer monitoring and processing of information leakage of protection. This paper briefly introduces the current leakage protection technology at present With the development of the coal mine. Only to leakage protection for the coal mine production safety escort.
