一、产品介绍
HOV系列过电压监视继电器适用于发电机、变压器、变电线路的继电保护装置中,作为过电压闭锁的启动元件。(适用于交流50/60Hz)
继电器的设定值和滞后返回可以通过电位器无级调节。
HOV series of Over-voltage supervisory relays serve as startup components for over voltage lockouin relay protection devices in generators , transformers, power transmission and transformation lines.(Areusedin AC50/60Hz)
The settings and lag and return times of the relay can be steplesslly adjusted with potentiometer.
