电气操作预警系统可生性研究

Feasibility Study on Electric Operation Early Warning System

从发电厂变电所电气系统的倒闸操作的实际出发,研究、开发出一种可防止带地线合刀闸的电气操作预警系统。介绍了电气操作预警系统的设计原理、系统功能,分析了装置动作过程。电气操作预警系统通过红外传感器检测隔离开关状态和地线状态,对二者的对应状态的合理性加以判断;如有人带地线合开关操作前,在解除开关的闭锁机构时,立即发出报警,从而避免发生误操作。指出此电气操作预警系统的设计方案是可行的。

An electric operation early warning system, which senses the status of isolated switches and grounding through infrared sensors and judges t he rationality of interrelation between the two,will give an immediate warning to avoid mishandling when someone with grounding tries to unlock the switches in an attempt to engage the switches.
