摘要
“１０ＫＶ、３５ＫＶ线路保护组合继电器”是许昌继电器研究所委托我们研制的继电器新型式。该继电器采用集成电路构成，集线路的速断保护、过电流保护及三相一次重合闸于一体。本文介绍组合继电器的构成原理。
KV、35KV line protection combination relay',is a new type of relay developed by us.We were entruseted by Xuchang Relay Research Institute with the development of it.The relay is made up of integrated circuits.The line instantaneous overcurrent protection and overcurrent protection are combined with the once 3-phase reclosure application to form a whole body.The paper introduce the structure principle of the combination relay。
