Interlocking device

The utility model discloses an interlocking device, which comprises a mounting seat and a locking arm, and is characterized in that the mounting seat is used for being mounted between two circuit breakers arranged side by side; the locking arm extends along the arrangement direction of the two circuit breakers, and the locking arm is slidably mounted on the mounting seat along the extension direction of the locking arm, so that one end of the locking arm slides to the upper part of an operating handle of one opening circuit breaker to limit the closing of the operating handle; and the other circuit breaker can be normally switched on and switched off. According to the technical scheme, the risk that two circuit breakers are switched on at the same time can be avoided. 本实用新型公开一种联锁装置，包括安装座和锁臂，安装座用于安装在两个并排设置的断路器之间；锁臂沿两个断路器的排布方向延伸设置，锁臂沿其延伸方向可滑动地安装在安装座上，以使锁臂的一端滑动至其中一个分闸断路器的操作手柄上方，以限制该操作手柄合闸；另一个断路器可正常合闸和分闸。本实用新型技术方案能够避免两个断路器同时合闸的风险。
