Abstract
The utility model relates to an indoor metal armored extraction type switch breaker dolly grounding device. The technical proposal of the utility model is that the primary grounding copper row positioned at the breaker dolly chassis is canceled; and a movable contact board is arranged at the contact position of the left side and the right side of the breaker dolly chassis and a track. The utility model has the advantage of ensuring the good grounding performance of the breaker dolly wherever the breaker dolly is pulled in the process of maintenance, thereby ensuring the safety of the maintainer.
Description
Technical field
The utility model belongs to the appliance switch cabinet device, particularly a kind of indoor metal armoring draw out switchgear circuit breaker dolly earthing device.
Background technology
Present indoor metal armoring draw out switchgear circuit breaker dolly earthing device, circuit breaker is installed as trolley type, and advancing is that circuit connects operating state, pulls out to be off state.Operating breaker is that dolly and cabinet are to move, and in order to guarantee maintainer's safety good earthing device must be arranged.Original circuit breaker dolly domain divides into ground connection compressed spring type contact ground connection.After the circuit breaker dolly was pulled out certain position, what the circuit breaker dolly can not be good contacted with ground connection compressed spring type contact, causes imperfect earth, can cause maintainer's unsafe factor is caused danger.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of indoor metal armoring draw out switchgear circuit breaker dolly earthing device is provided.Reach dolly no matter move assorted petty position to, can both guarantee the ground connection that the circuit breaker dolly is good, guarantee maintainer's safety.
The technical solution of the utility model is:
A kind of indoor metal armoring draw out switchgear circuit breaker dolly earthing device is characterized in that: cancel the ground connection copper bar on original circuit breaker dolly chassis, the left and right sides and the track contact site of circuit breaker dolly chassis is provided with removable touch panel.
The utility model effect is:
Circuit breaker dolly in the electrical maintenance process can both guarantee the ground connection that the circuit breaker dolly is good no matter move assorted petty position to, guarantees maintainer's safety.
