Description

A kind of outdoor AC high-voltage isolating switch

Technical field

The utility model relates to field of electrical equipment, is a kind of isolating switch specifically.

Background technology

In power equipment, isolating switch consumption is huge, and its effect is separated reliably high voltage source, guarantees the safety of operating personnel.Chinese Patent Application No. 201020635820.5 1 kinds of outdoor AC high-voltage isolating switches, this isolating switch includes switch underframe, bearing spider is equipped with respectively in the two ends of switch underframe, bearing spider is fixed with post insulator, conduction disconnecting link is equipped with on the top of two post insulators, and the bottom dislocation between two post insulators is equipped with girt and forms single-pole isolator; The transmission of single-pole isolator is the bearing spider on console switch underframe, on bearing spider, the post insulator rotation axis of side turns clockwise 90 °, drive the post insulator of opposite side to being rotated counterclockwise 90 ° by the girt of two post insulator intercolumniations, conduction disconnecting link separates or closes.As shown in Figure 3, the conduction disconnecting link contact of this patent is linear contact lay, therefore, easily comes in contact bad and electric discharge phenomena.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide and a kind ofly contacts well and the isolating switch of electric discharge phenomena not easily occurs, and concrete scheme is as follows:

A kind of type outdoor AC high-voltage isolating switch, comprises conduction disconnecting link, it is characterized in that: described conduction disconnecting link comprises conductive contact finger and conductive contact seat; Described conductive contact finger is all communicated with binding clip with conductive contact seat; The slideway matched with conductive contact finger size is set in conductive contact seat, in the inner space of described conductive contact finger, expansion chamber is set; The cross section of described slideway place conductive contact seat and conductive contact finger is inclined-plane; The arranged outside fairlead of described conductive contact finger; The outside of described fairlead and the outside of conductive contact seat are integral insulation cover.

The utility model has the advantages that: adopt face contact, add contact area, ensure that contact is good, in addition, be provided with fairlead, be not only convenient to the grafting of conductive contact seat and conductive contact finger, the more important thing is, isolate insulating case conductive contact finger, prevent the heat of electric discharge generation to the damage of insulating case.

Accompanying drawing explanation

Fig. 1 is the structural representation of this conduction disconnecting link;

Fig. 2 is overall structure schematic diagram;

Fig. 3 is the conduction disconnecting link structural representation of prior art.

Embodiment

Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises conduction disconnecting link 10, and described conduction disconnecting link 10 comprises conductive contact finger 2 and conductive contact seat 1; Described conductive contact finger 2 is all communicated with binding clip with conductive contact seat 1; In described conductive contact seat 1, the slideway matched with conductive contact finger size is set, in the inner space of described conductive contact finger 2, expansion chamber 3 is set; The cross section of described slideway place conductive contact seat and conductive contact finger is inclined-plane 6; The arranged outside fairlead 5 of described conductive contact finger 2; The outside of described fairlead 5 and the outside of conductive contact seat 1 are integral insulation cover 4.

The effect of described expansion chamber is the good contact ensureing conductive contact seat and conductive contact finger, and therefore, the outside expansion of this expansion chamber is the important inventive point of the application; This expansion chamber inside can arrange physical unit and ensure that it outwards expands, and as adopted spring, utilizes the elastic force of spring to make it outside expansion; In addition, can also chemical method be adopted, as utilize conductive contact finger and conductive contact seat be about to the electric discharge benefit produced when contact the heat that produces to heat the material in expansion chamber, make it volume increase, as employing silicon rubber and so on material etc.

Claims
