摘要
从短路保护、过载保护、漏电闭锁和漏电保护、暂态过电压保护、温度保护等方面介绍了矿用组合开关控制保护技术的现状;指出矿用组合开关控制保护技术存在继电保护不全面、保护误动作、控制方式繁琐、自诊断功能简单等问题;提出了矿用组合开关控制保护技术的发展趋势,包括继电保护方法完善、软件滤波方法改进、控制集约化、智能自诊断和远程诊断等。
Present situation of control and protection technology for mine-used combined switch was introduced from aspects of short circuit protection, overload protection, leakage lockout and leakage protection, transient overvoltage protection and temperature protection. Problems of control and protection technology for mine-used combined switch such as incomplete relay protection, protection misoperation, complicated control mode and simple self-diagnosis were pointed out. Development trend of control and protection technology for mine-used combined switch were put forward, including improvement of relay protection method and software filtering method, control intensification, intelligent self-diagnosis and remote diagnosis.
