摘　　要：电力系统中两种常规的断路器失灵保护方式均不适用于单一进线线-变组结构的断路器。为此,对常规方式的二次回路进行改进,设计出一种基于远跳功能的线-变组断路器失灵保护。该方案具有二次回路简单、建设成本低等优点,可为从事继电保护的工作者提供一条新的思路。The two conventional breaker failure protection approaches applied in power system are not suitable for the breakers with the structure of single incoming line-transformer banks.As for this,a breaker failure protection for such a line-transformer bank is designed based on the remote tripping function by modifying the conventional secondary circuits.The scheme appears the advantages such as a simple structure of secondary circuit and low construction cost,which can be regarded as a new idea for workers who are engaged in relay protection.
