目前变电站主变压器的中低压侧主进开关或母联开关之间的防误闭锁关系设置中,经常未设置开关与开关之间的闭锁关系,文章以低压侧主进开关及低压侧母联为例(中压侧与之相同),阐述在全面考虑双主变并列运行这种典型运行方式下,如何设置防误闭锁逻辑关系,防止误操作事故的发生。
目前變電站主變壓器的中低壓側主進開關或母聯開關之間的防誤閉鎖關繫設置中,經常未設置開關與開關之間的閉鎖關繫,文章以低壓側主進開關及低壓側母聯為例(中壓側與之相同),闡述在全麵攷慮雙主變併列運行這種典型運行方式下,如何設置防誤閉鎖邏輯關繫,防止誤操作事故的髮生。

In the setting of low voltage side main switch or bus connection switch misoperation-prevention locking relationship, the locking relationship between switches is often ignored. Taking low voltage side main switch and low voltage bus connection switch as examples (medium voltage side is the same), the main purpose of this article is to explain how to set the miss operation blocking logical relationship to prevent misoperation under the typical operation way of double main transformer parallel operation.
