Abstract
The utility model relates to a temperature rise reducing device of a fixed contact of a drawing-out type high-voltage switch cabinet, which can effectively solve the problems of the existing drawing-out type high-voltage switch cabinet that the construction cost of a copper bar is high, the heating amount of a connecting part of an aluminum bar fixed contact and a bus bar is great and the temperature rise exceeds the standard. The technical scheme is as follows: the temperature rise reducing device comprises a fixed contact cover and a copper-aluminum transition lap joint; the fixed contact cover is internally provided with the fixed contact; the fixed contact is connected with the copper-aluminum transition lap joint; and the copper-aluminum transition lap joint passes through the fixed contact cover and an aluminum bar. The temperature rise reducing device of the fixed contact of the drawing-out type high-voltage switch cabinet disclosed by the utility model has the advantages of novel and unique structure, simplicity and reasonability, convenience for machining and manufacturing, low cost, and good social and economic benefits.
Description
Technical field
The utility model relates to pull-out type high-voltage switch gear cabinet static contact place and reduces the temperature rise device.
Background technology
Existing pull-out type high-tension switch cabinet busbar generally adopts two kinds of materials, or adopts copper bar, or adopts aluminium row, and employing copper bar contact-making surface conductive capability is good, the temperature rise of fixed contact contact position is low, but cost is high, cost is high; Adopt aluminium line up low, cost is low, but the pull-out type high-tension switch cabinet especially fixed contact and busbar junction caloric value are greatly, temperature rise often exceeds standard.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model just provides a kind of pull-out type high-voltage switch gear cabinet static contact place and reduces the temperature rise device; The busbar that can effectively solve existing pull-out type high-tension switch cabinet adopts the copper bar cost high, employing aluminium row's fixed contact and the problem that busbar junction caloric value is big, temperature rise exceeds standard.
Originally be that the technical scheme that utility model solves is, comprise stationary contact head-shield and copper-aluminium transition lap joint, in the stationary contact head-shield fixed contact is housed, fixed contact links to each other with the copper-aluminium transition lap joint, and the copper-aluminium transition lap joint is passed the stationary contact head-shield and linked to each other with aluminium row.
The utility model novel structure is unique, advantages of simple, and convenient processing and manufacture, cost is low, and good reliability has good society and economic benefit.
Description of drawings
Fig. 1 is the structural front view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Provided by Fig. 1, the utility model comprises stationary contact head-shield and copper-aluminium transition lap joint, and fixed contact 1 is housed in the stationary contact head-shield 4, and fixed contact 1 links to each other with copper-aluminium transition lap joint 2, and copper-aluminium transition lap joint 2 is passed stationary contact head-shield 4 and linked to each other with aluminium row 3.
In order to guarantee result of use; Described copper-aluminium transition lap joint 2 is linked together by the copper body 2a of the aluminium body 2b of the first half and the latter half and constitutes, and the part of aluminium body 2b contacts with aluminium row 3, connects through screw; The part of copper body 2a contacts with static iron core 1, connects through screw.
When the utility model used, owing to adopted the part of copper body 2a in the copper-aluminium transition lap joint 2 to link to each other with fixed contact 1, so the contact-making surface conductive capability is good, the contact position temperature rise was low; The part of aluminium body 2b links to each other with aluminium row in the copper-aluminium transition lap joint 2, has reduced cost.
The utility model novel structure is unique, advantages of simple, and convenient processing and manufacture, cost is low, and good reliability has good society and economic benefit.
