PLC在煤矿供电系统中的应用

介绍了一种由井上计算机监控系统以及井下新型隔爆馈电开关组成的煤矿井下电力控制系统。PLC是井下智能馈电开关的核心,而VC++是井上计算机监控系统的主要工具。由于该系统对井下电网实时数据的观测,它能够实现漏电保护、短路保护、过载保护、过压以及欠压保护等,因而该装置可以大大提高煤矿供电系统的安全可靠性。

Application of PLC in Coal Supply System

This paper mainly introduces a kind of computer monitoring system and by inoue underground explosion of new feeder switch between the coal mine underground power and control system.PLC is the core of the underground intelligent feeding switch,and VC++ is computer monitoring system of the main inoue tools.Because the system of underground power grid the real data of observation,it will be able to realize the leakage protection,short circuit protection,overload protection,over-voltage and voltage protection,so the device can greatly improve the safety and reliability of the power supply system of coal mine.
