The invention provides a centrally installed switchgear breaker maintenance locking device. The centrally installed switchgear breaker maintenance locking device comprises a clamping part for fixing an operation block in a breaker, a rotating part for controlling the tightness of the clamping part through rotation, and a locking part for locking the rotating part. By rotating the rotating part, the tightness of the clamping part can be controlled, so that the operation block in the breaker is occluded and fixed. And then the rotating part is locked by the locking part, so that other people cannot operate the device, and the accidents are prevented. 本发明提供了一种中置柜断路器检修闭锁装置，包括对断路器内的操作块固定的卡接部件、通过旋转对卡接部件进行松紧控制的转动部件，以及将转动部件锁定的锁定部件。通过对转动部件进行旋转，即可将卡接部件进行松紧控制，从而将断路器内的操作块咬合固定，然后将锁定部件将转动部件进行锁定，使他人不能进行操作，从而防止意外发生。
