摘　　要：电气联锁通过二次电缆、辅助接点在间隔内和间隔间形成最基本的联锁关系,是新建、改扩建变电站投运前验收的重要内容之一。以某变电站220 kV系统双母线接线GIS设备为例,结合验收经验,论述线路、主变高压侧、电压互感器、母联等间隔电气联锁回路的基本原理和验收方法,为变电运维人员检测电气联锁逻辑、查找故障提供参考。Electrical interlocking forms the most basic interlocking relationship within and between compartments through secondary cables and auxiliary contacts,which is one of the important contents of acceptance before the operation of newly-built,reconstructed and expanded substations.Taking the 220 kV double bus connection GIS equipment of a substation as an example,combined with the acceptance experience,analyzes the basic principles and acceptance methods of the electrical interlocking circuits of the line,the high-voltage side of the main transformer,the voltage transformer,the bus coupler and other intervals,providing reference for the substation operation and maintenance personnel to accept the electrical interlocking logic and find faults.
