摘　　要：文中分析了500 kV输电线路远方跳闸保护的原理,介绍了远跳就地判别装置的工作逻辑,通过实例提出了现有线路保护加装独立就地判别装置的设计方案,对同类型的保护改造有一定的借鉴意义。The paper analyzes the principle of remote tripping protection in 500 kV transmission line,it also introduces the working logic of the local discriminating device. Through one example,this paper presents a design scheme of fixing the local discriminating device on line-relays,which is a good reference to the same relay alteration.
