Description
Technical field
High-Voltage Electrical Appliances field is the utility model is related to, specifically a kind of outdoor disconnector.
Background technology
In the outdoor three-phase formula pole type breakers of 10 ~ 40.5kV grades on the market, automatic circuit and on-load switch, very greatly
A part of ratio needs supporting disconnecting switch 1, and load isolation and the visible function of fracture are realized in circuit maintenance work.Such as figure
Shown in 1 and 2, traditional switch 1 in the market sets traditional knife plate 2 and face contact 3 thereon, and face contact 3 is typically dashed forward using pressure
Facet structure, the drawbacks of obvious be present：Because outdoor disconnector frame size is big, isolate the position of related features of static contact seat
Greatly, actually with the contact effect of knife plate monomer and bad；For the good contact for ensureing knife plate monomer with isolating static contact seat, city
Common practice be：Increase the contact thrust of knife plate monomer；So, knife plate monomer thrust is crossed conference and caused：Divide-shut brake
Operating physical force is exceeded, and what disconnecting switch can not be during separating brake, and contact system breaking-closing operating because kill after closing a floodgate is excessive
The problems such as abrasion.
Utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of outdoor disconnector, considerably increases peak
The contact clamping force being worth under current condition, solve outdoor isolation knife using a kind of method of simple economy and bear peak value tolerance electricity
The ability of stream and KA Rms.
To achieve these goals, the concrete scheme that the utility model uses for：
A kind of outdoor disconnector, including isolation knife plate, isolation knife plate include two knife plate monomers being oppositely arranged, two
Two contacts are set side by side with the opposite side of the knife plate monomer, width of two contacts along knife plate monomer is equal
Even distribution, the elongated slot that a length direction along knife plate monomer extends also is begun between two contacts；Two knives
The outside of plate monomer is respectively fixedly installed a conducting parts.
Described contact is surrounded by a cambered surface and a plane, and its midplane is fixed and is fitted on the knife plate monomer.
One end of the elongated slot penetrates the contact jaw of the knife plate monomer, and the other end of elongated slot is through with one and is opened in
Through hole on knife plate monomer.
Two described contacts are symmetrical arranged on the elongated slot.
The length of the elongated slot is equal to the 1/7 ~ 1/6 of the length of the knife plate monomer.
The conducting parts are arranged to rectangle tabular structure.
The length direction of the conducting parts is parallel with the length direction of the knife plate monomer.
The width of the conducting parts is equal with the width of the knife plate monomer.
The conducting parts are fixedly connected by bolt with the knife plate monomer.
Beneficial effect：
1st, the utility model is contacted using two contacts with isolation static contact seat, and between two contacts also
An elongated slot is offered, makes the knife plate part of elongated slot both sides there is certain deformation space, can be even closer with dynamic point contact
Ground is contacted with isolation static contact seat；
2nd, by increasing conducting parts in the outside of knife plate monomer, when normal occlusion divides disconnecting switch, without electric current by being somebody's turn to do
Part does not interfere with contact pressure, does not interfere with the normal operating of disconnecting switch；Electric current by when, conducting parts are magnetized,
Attraction is produced each other, directly increases the contact pressure of knife plate monomer, is advantageous to knife plate monomer tolerance peak point current electricity
The impact of power.

Embodiment
Embodiment of the present utility model is illustrated below according to accompanying drawing.
As shown in Figures 3 and 4, a kind of outdoor disconnector, including isolation knife plate, what isolation knife plate was oppositely arranged including two
Knife plate monomer 4, is set side by side with two contacts 5 on the opposite side of two knife plate monomers 4, point contact 5 by a cambered surface and
One plane is surrounded, and its midplane is fixed and is fitted on knife plate monomer 4.
Width of two contacts 5 along knife plate monomer 4 is uniformly distributed, and one is also begun between two contacts 5
The elongated slot 6 of length direction extension of the bar along knife plate monomer 4, two contacts 5 are symmetrical arranged on elongated slot 6.One end of elongated slot 6 is passed through
The contact jaw of logical knife plate monomer 4, the other end of elongated slot 6 are through with a through hole being opened on knife plate monomer 4, elongated slot 6
Length is equal to the 1/6 of the length of knife plate monomer 4.The setting of elongated slot 6 makes a part for the knife plate monomer 4 of its both sides have necessarily
Deformation space, it can closely be contacted with dynamic point contact 5 with isolation static contact seat.
A conducting parts 7 are respectively fixedly installed in the outside of two knife plate monomers 4.Conducting parts 7 are arranged to rectangle
Platy structure, conducting parts 7 are fixedly connected by bolt with the knife plate monomer 4.The length direction of conducting parts 7 and knife plate list
The length direction of body 4 is parallel.The width of conducting parts 7 is equal with the width of knife plate monomer 4.Conducting parts 7 are preferably carbon steel, electricity
The soft magnetism material such as work pure iron or silicon steel sheet.When normal occlusion divides disconnecting switch, there is no electric current to pass through Bu Huiying on conducting parts 7
Ring the pressure of point contact 5 and influence the normal operating of disconnecting switch；Electric current by when, conducting parts 7 are magnetized, each other
Attraction is produced, knife plate monomer 4 is directly increased and puts the pressure of contact 5, it is electronic to be advantageous to the tolerance peak point current of knife plate monomer 4
