Abstract

The invention provides a trip lock-out device and box type fixed alternating current metal closing switch equipment, relating to the technical field of power equipment. The trip lock-out device comprises a mounting rack, a trip shaft, a lock-out handle, an operation handle, a first transmission component and a second transmission component. When rotating to the position of the trip lock-out device, the lock-out handle drives the first transmission component to rotate so as to drive a trip to rotate; and when being pressed down, the operation handle drives the second transmission component to move so as to drive the trip to rotate. According to the trip lock-out device, two operation paths capable of finishing the brake separation of a circuit breaker are configured, and when the first operation fails, the brake separation of a circuit breaker can still be finished by virtue of the second operation, so that the reliability of the lock-out operation is improved, and the safety of peopleand equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a tripping locking device and a box-type fixed AC metal-enclosed switchgear. Background technique [0002] Box-type fixed AC metal-enclosed switchgear is a complete set of indoor power distribution equipment, which is suitable for receiving and distributing network power in 12-40.5KV three-phase AC 50Hz power system, and controlling, protecting and monitoring the circuit. [0003] At present, when the user needs to start the operation turntable, he first presses the corresponding operation handle of the operation turntable, and then needs to trip and lock the isolation knife and ground knife of the box-type fixed AC metal-enclosed switchgear with the circuit breaker, and the user turns the operation When the locking handle on the plate reaches the breaking and locking position, the locking handle turns to drive the tripping plate to move, thereby driving the trip...
