Abstract
A kind of Combined-type insulating part for vacuum circuit-breaker.It is characterized in that: comprise insulating sleeve, barrier box, described insulating sleeve two ends are provided with cylindrical cavity volume, and are respectively equipped with vacuum tube, insulated tension pole, be provided with rectangle cavity volume, and be provided with vacuum tube conductive strips in the middle of described insulating sleeve; Described barrier box is provided with fixed contact, isolation knife, described isolation knife one end and barrier box hinged, and be electrically connected with vacuum tube, the other end is provided with the moving contact corresponding with fixed contact.Its advantage is insulating sleeve, barrier box to be combined into contact box separately as a module, and not only structure is simple, and easy to assembly.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, is specifically related to a kind of Combined-type insulating part for vacuum circuit-breaker.
Background technology
Vacuum circuit-breaker is one of switchgear common in electrical system, its structure mainly comprises operating mechanism, is built-in with the arc control device unit of current transformer and transmission mechanism etc., due to existing vacuum circuit-breaker to have point, closing speed is fast, compact conformation, can fast and effeciently control the features such as the break-make of electrical system, therefore be widely used among various high-voltage electric system.
Existing vacuum circuit-breaker generally adopts the pole vertically arranged, be embedded in pole by numerous conductive parts relevant with circuit breaker for vacuum interrupter, its assembly difficulty is large simultaneously.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of Combined-type insulating part for vacuum circuit-breaker, and structure is simple, easy to assembly.
The technical scheme that the utility model adopts: a kind of Combined-type insulating part for vacuum circuit-breaker, comprise insulating sleeve, barrier box, described insulating sleeve two ends are provided with cylindrical cavity volume, and be respectively equipped with vacuum tube, insulated tension pole, be provided with rectangle cavity volume in the middle of described insulating sleeve, and be provided with vacuum tube conductive strips; Described barrier box is provided with fixed contact, isolation knife, described isolation knife one end and barrier box hinged, and be electrically connected with vacuum tube, the other end is provided with the moving contact corresponding with fixed contact.
The supporting seat for supports insulative sleeve is integrally formed with outside described insulating sleeve.
Bolt hole is provided with bottom described supporting seat.
The outer wall that described insulating sleeve is provided with vacuum tube one end is provided with insulation full skirt.
Described insulation full skirt is provided with 5.
Described fixed contact is Mume flower contact.
Described insulating sleeve, barrier box are bolted to connection.
Described insulating sleeve, barrier box are integral type structure.
The beneficial effects of the utility model are: adopt above scheme, insulating sleeve, barrier box are combined into contact box separately as a module, distinguish mounting vacuum tube, insulated tension pole, vacuum tube conductive strips, moving contact, fixed contact again, not only structure is simple, and easy to assembly.
