Abstract
The invention relates to an isolation switch for isolating an arc extinguishing cabinet. The isolation switch comprises a base and an isolation static contact and a grounding static contact arranged on the base, wherein an isolation moving contact is arranged at the upper end of the isolation static contact; a grounding moving contact is arranged at the upper end of the grounding static contact; the isolation static contact and the isolation moving contact are mutually connected through threads; the grounding static contact and the grounding moving contact are mutually connected through threads; an isolation blade is arranged between the isolation moving contact and the grounding moving contact; the outer side of the isolation blade is covered with an insulating protection jacket; an insulating pull rod is fixed on the outer side of the insulating protection jacket and fixedly connected with the isolation blade through a first bolt; and an open hole for inserting a grounding switch disconnector is formed at the upper end of the grounding moving contact. In the invention, the grounding moving contact does not fall automatically for sure, the problem of bad contact between the grounding static contact and the grounding moving contact in the prior art is solved, potential safety hazards are avoided, and the service life of the product is prolonged.
Description
Technical field
The present invention relates to electrical equipment technical field is and in particular to a kind of disconnecting switch for isolating arc extinguishing cabinet.
Background technology
In prior art, the grounding static contact for isolating the disconnecting switch of arc extinguishing cabinet is divided in long-term with ground connection moving contact
Occur during conjunction mutually to extrude, that is, the fingertip of grounding static contact and the knife bar of ground connection moving contact occur mutually to extrude, and cause to connect
Ground static contact fingertip occur a certain degree of deformation, grounding static contact with ground connection moving contact tightness degree between the two just by
Gradually reduce so that the grounding static contact of disconnecting switch and ground connection moving contact loose contact, when serious, occur that ground connection moving contact takes off
The phenomenon falling, so can affect normally to use, bring potential safety hazard to safety in production.
Content of the invention
It is an object of the invention to provide a kind of disconnecting switch for isolating arc extinguishing cabinet, to solve to be used in prior art
The grounding static contact of disconnecting switch of isolation arc extinguishing cabinet and the problem of ground connection moving contact loose contact.
For achieving the above object, present invention employs technical scheme below:
A kind of disconnecting switch for isolating arc extinguishing cabinet, including base and located at the isolation static contact on base and ground connection stationary contact
Head, the upper end of described isolation static contact is provided with isolation moving contact, and the upper end of grounding static contact is provided with ground connection moving contact, described isolation
Static contact is connected with each other by screw thread with isolation moving contact, and described grounding static contact is interconnected by screw thread phase with ground connection moving contact
Connect, the isolation blade between described isolation moving contact and ground connection moving contact, the outside of isolation blade is arranged with insulation protective jacket, institute
The outside stating insulation protective jacket is fixed with insulated tension pole, and it is fixing with isolation blade even that described insulated tension pole passes through the first bolt
Connect, the upper end of described ground connection moving contact is provided with the perforate for inserting earthed switch disconnecting link.
Improvement further as technique scheme:
Described isolation moving contact is along the circumferential direction sequentially connected by multiple conducting strips and constitutes.
Described ground connection moving contact is along the circumferential direction sequentially connected by multiple conducting strips and constitutes.
Described isolation moving contact is fixedly connected with isolation blade by the second bolt.
As shown from the above technical solution, in the present invention enough guarantee be grounded moving contact will not Automatic-falling, and then make ground connection
Contact between static contact and ground connection moving contact is good, thus efficiently solving grounding static contact of the prior art and connecing
The bad problem of earthquake contact, provide and effectively reliably ensure for safety in production, it is to avoid potential safety hazard, improves product
The service life of product.
