常规信号继电器的应用电路和常见故障

The application of conventional signal relay circuit and the common faults

信号继电器是对电力系统进行继电保护的重要元件之一。尽管我国的电力系统自动化程度处于不断提升的阶段中,但是信号继电器使用的范围却在逐渐缩小。目前在常规形式的变电站内,信号继电器的使用数量依然比较多,使用时间的延长使得继电器可能出现一些故障,为了保证变电站的稳定运行,需要采取有效的措施来应对和解决这些故障,本文主要就常规的信号继电器的应用电路以及常见的故障形态进行了分析介绍。

the signal relay is one of the important components of power system relay protection.Although our country’s electric power system automation is in rising stage, but in narrowing the scope of using signal relay.At present in conventional forms of transformer substation, the use of signal relay quantity still more, using the extension of time makes the relay may appear some fault, to ensure the stable operation of the transformer substation, need to take effective measures to cope with and solve these faults, this paper is the application of conventional signal relay circuit and the common failure forms are analyzed.
