煤矿供电系统继电保护与供电安全研究

Research on Relay Protection and Power Supply Safety of Coal Mine Power Supply System

现阶段,我国煤矿行业迅猛发展,同时煤矿事故频发,使得人们对井下作业的安全性越来越重视,特别是煤矿井下的电力系统安全问题。在煤矿中,供电系统的安全如果出现问题,对整个煤矿作业的安全都会有严重影响,为了更好地保证供电安全,供电系统须安装继电保护设备,该设备也是煤矿井下作业中的重要设备,会直接决定了井下的供电安全,因此其安全稳定等方面的要求更高。文章主要对当前煤矿供电系统继电保护设备的类型、工作原理、配置要求、技术细节进行阐述,分析了当前在煤矿供电系统继电保护设备中存在的问题及故障检测手段,提出了管理煤矿供电系统继电保护的相关方案,以期给煤矿供电安全提供参考。

At present,the rapid development of China’s coal mining industry has also brought certain risks.More and more coal mine accidents have occurred,which has also made people pay more attention to the safety of underground operations,especially the safety of the power system in coal mines.In coal mines,if there is a problem with the safety of the power supply system,it will have a serious impact on the safety of the entire coal mine operation.In order to better ensure power supply safety,relay protection equipment must be installed in the power supply system,which is also an important equipment in coal mine underground operations,and will directly determine the safety of underground power supply.Therefore,the requirements for safety and stability of relay protection equipment in coal mines are relatively higher.This article mainly elaborates on the types,working principles,configuration requirements,and technical details of relay protection equipment in the current coal mine power supply system.It analyzes the problems and fault detection methods currently existing in the relay protection equipment in the coal mine power supply system,and proposes relevant solutions for managing the relay protection of the coal mine power supply system.It is hoped that this can provide reference for the safety of coal mine power supply.
