摘要
220kV智能化变电站中,220k V断路器一般配置双重化的智能终端,相当于两套独立的操作箱。与常规综自站带双跳功能单操作箱相比,其防跳回路实现方式不同。本文在对常规操作箱防跳回路分析的基础上,提出了双重化智能终端防跳回路实现的方法。
In 220kV intelligent substation, 220kV breaker is often configured double RPIT, equivalent to two separate operative-boxes. Compared with normal integrated automation system substation, the anti-jumping circuit performs in a different way. Based on the analysis of anti-jumping circuit for nomal operative-box, this paper proposes a method for dual-configured RPIT.
