Abstract
The invention discloses an outdoor alternating-current high-voltage isolating switch which comprises conductive disconnecting links. The outdoor alternating-current high-voltage isolating switch is characterized in that the conductive disconnecting links comprise conductive contact fingers and conductive contact bases; both the conductive contact fingers and the conductive contact bases are communicated with jointing clamps; the conductive contact bases are internally provided with slide rails matched with the conductive contact fingers in size, and the internal spaces of the conductive contact fingers are internally provided with expansion cavities; the cross sections, at the positions of the slide rails, of the conductive contact bases and the conductive contact fingers are inclined faces respectively; the outer sides of the conductive contact fingers are provided with guide sleeves; both the outer sides of the guide sleeves and the outer sides of the conductive contact bases are provided with overall insulating sleeves; the conductive disconnecting links are further provided with through holes, and the through holes are formed below the guide sleeves and the left sides and the right sides of the guide sleeves in a symmetrical mode. The outdoor alternating-current high-voltage isolating switch has the advantages that the through holes are formed, the heat generated by discharging can be discharged, and damage to the conductive disconnecting links is avoided.
Description
Technical field
The present invention 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.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide and a kind ofly contact well and the isolating switch of electric discharge phenomena not easily occurs, concrete scheme is as follows:
A kind of 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 described electric shock touch base, 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.
Also be provided with through hole, described through hole is separately positioned on below and the left and right sides symmetric position of fairlead.
The through hole of both sides and the angle of horizontal plane are 30-45 °.
Advantage of the present invention is: 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, isolated insulating case conductive contact finger, prevent the heat of electric discharge generation to the damage of insulating case.Owing to being provided with through hole, the heat that electric discharge can be produced is discharged, and avoids the damage of conduction disconnecting link.
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;
Fig. 4 is A-A generalized section in Fig. 1.
Embodiment
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes conduction disconnecting link 10, 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 electric shock touch base 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.
Also be provided with through hole 7, described through hole 7 is separately positioned on below and the left and right sides symmetric position of fairlead 5.The heat that sparkover can produce by the setting of this through hole is discharged outside disconnecting link, ensure that device security.
The through hole 7 of both sides is 30-45 ° with the angle a of horizontal plane.The setting of this angle can ensure that rainwater can not enter conduction disconnecting link inside, thus the safe operation of the equipment of guarantee.
