Background technology
Generation current factory, power transformation be in one's power in the change distribution of industrial and mining enterprises, skyscraper, and using many is intermediate switchgear cabinet.And the repair and maintenance of intermediate switchgear cabinet needs the supporting use of various dollies, as electrical verification dolly, ground connection dolly etc.These vehicle structures are more or less the same, and function is but had nothing in common with each other, and have increased the manufacturing cost of intermediate switchgear cabinet, have caused the idle of dolly.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, maintenance dismounting and composite type dolly easy to detect.This dolly both can be used for the charged situation of sense switch cabinet, can be used as earthing device again and used.
The purpose of this utility model is achieved by the following technical programs:
A kind of switch cubicle multifunctional dolly, comprise dolly car body, three last contact arms, three following contact arms, contact arm rear end, each following contact arm rear end are separately fixed on the dolly body inner side on each, the contact arm front end is fixedlyed connected with last moving contact respectively on each, the contact arm front end is fixedlyed connected with lower moving contact respectively under each, contact arm front end, following contact arm front end are set with the insulating case box on each, be respectively equipped with transducer in contact arm rear end, the following contact arm rear end on each, the dolly car body outside is provided with electrification display, ground connection disconnecting link.The dolly body inner side also is provided with ground connection row, and described ground connection row's upside and ground connection disconnecting link one end are hinged, and ground connection row downside links to each other with the dolly car body; When the ground connection disconnecting link closed, the ground connection disconnecting link other end was connected with last contact arm Connection Block.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid switch cubicle multifunctional dolly, the wherein said dolly car body outside also is provided with ground connection switch operation mechanism, described ground connection switch operation mechanism comprises operating handle, disk, pull bar, described disk vertically is journaled into the dolly car body outside, operating handle and disk diameter are to being connected, pull bar one end and disk off-centre are hinged, and the pull bar other end and ground connection disconnecting link one side are hinged.
The utility model is simple in structure, and is easy to use.When switch cubicle needs repair and maintenance, the ground connection disconnecting link closes, because the ground connection disconnecting link other end is connected with last contact arm Connection Block, last moving contact successively is connected with ground connection row by last contact arm Connection Block, ground connection disconnecting link, make intermediate switchgear cabinet ground connection, guarantee electric equipment in maintenance personal's safety inspection switch cubicle, at this moment the utility model uses as the ground connection dolly; The ground connection disconnecting link of leaving behind, the ground connection disconnecting link other end is thrown off upward contact arm Connection Block, ground connection row breaks away from the ground connection disconnecting link and is connected, and at this moment the utility model is as the use of electrical verification dolly, can be from real-time voltage, the current parameters of the electrification display sense switch cabinet power transmission and distribution of switch cubicle front side.The utility model integrates ground connection, electroscope function, and the many usefulness of a car had both reduced manufacturing cost, has avoided disposing many dollies again and has used the waste that causes.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
