摘　　要：在早期的输电线路保护设计中对远跳保护没有统一的规范,因而部分厂家生产的操作箱没有足够的TJR继电器接点供远跳保护使用。针对此类情况,以鄂尔多斯电业局北郊220 kV变电站255布北Ⅰ线为例,提出一种远跳回路改造方法:利用FCX-12J型操作箱中的2个备用中间继电器完善线路的远跳回路。本次改造时间短、投资少;改造后的远跳回路清晰、抗干扰能力强,而且降低了误碰概率,为解决类似问题提供了借鉴。In the early design of transmission line relay is no uniform standard of distant trip relay, so that manufacturers operation cabinet does not have enough TJR relay contact for the distant trip relay. For such cases, Ordos Electric Power Bureau in the 220 kV northern substation of BubeiⅠ line, proposes a distant trip circuit for renovation methods：FCX-12 J type 2 spare relay of operation cabinet complete line of distant trip relay circuit.Renovation time is short, small investment; distant trip relay circuit clear after the transformation, anti Interference ability, but also reduces the probability of erroneous touch,to solve similar problems to provide a reference.
