Background technology
Box fixes switchgear assembly --- and XGN cabinets are as a kind of important switchgear assembly, in 10kV power trains Using having a large capacity and a wide range in system, its reliability of operation is directly connected to the safe and stable of Operation of Electric Systems.Disconnecting switch is Main components in XGN cabinets, play a part of conducting transmission electric energy under "on" position, safety is then undertaken under inspecting state Isolate the critical function of main circuit.The disconnecting switch used in XGN cabinets mainly has two kinds of models of GN30 types and GN22 types, wherein with GN30 type disconnecting switch occupies absolute quantity.
In recent years, in the operation troubles statistics of high-tension switch cabinet, fault isolating switch occupies very big ratio, particularly Heavy current disconnecting switches(More than rated current 3150A)Step-down incoming line cabinet or mother segmentation cabinet are typically employed in, once occur Quality problems, the safe and stable of power network will be seriously affected.The reason for heavy current disconnecting switches failure is more is summarized, is mainly had Three aspects:First, GN30, from popularization and application are designed into close to 30 years, Earlier designs carry certain limitation;Second, in recent years Load increases sharply;Third, the operation time limit is longer, running lacks enough maintenances.Above-mentioned three aspects reason, common manifestation It is too high for temperature rise in disconnecting switch longtime running, and finally trigger mechanical breakdown, insulation fault.
Important component of the switch contact as disconnecting switch, switch contact how is improved, reduce high-current switch and touch Operating temperature rise, so as to improve security, the reliability of disconnecting switch in operation, is significant.
Utility model content
For overcome the deficiencies in the prior art and the problem of exist, the utility model provides one kind and is applied to the big electricity of high-tension apparatus Switch contact is flowed, rapid heat dissipation is safe and reliable to operation.
The utility model is achieved through the following technical solutions:
One kind is applied to high-tension apparatus high-current switch contact, including conductive contact and base, the conductive bread of contact three enclose Grip base, conductive contact are mutually fixed by fixing device with base, the conductive contact by more sheets of conductive piece be laminated bending and Into the front portion of conductive contact and both sides afterbody are that more sheets of conductive piece heats integral structure, and two middle side parts of conductive contact are more Piece conducting strip split blade type structure.
The fixing device includes connecting bolt and nut, and connecting bolt concatenates the afterbody and base of conductive contact both sides, Nut check is on connecting bolt.
The both ends of the connecting bolt are serially connected with spring steel plate and adjustable spring, and spring steel plate is affixed on conductive contact.
The nut and connecting bolt are manufactured by non-magnetic stainless steel material.
The spring steel plate is by non-magnetic spring steel making.
The quantity of the conducting strip is 60-150 pieces.
The conducting strip is 0.1mm T2 copper sheets.
The conductive contact is axe shape.
The base is provided with multiple heat emission holes and radiating groove.
The base manufactures for aluminum alloy materials.
Two middle side parts of conductive contact of the present utility model are more sheets of conductive piece split blade type structure, and the structure can retain thin slice Characteristic, play a part of soft connection, ensure the being adjusted flexibly property and electric conductivity of conductive contact, and due to there is multi-disc combination, Do not interfere with high current by can also increase surface area, improving radiating effect, total is simple, and stability is good, is applied to The operating temperature rise of heavy current disconnecting switches can be effectively reduced in disconnecting switch, so as to improve the safety of disconnecting switch in operation Property, reliability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the mplifying structure schematic diagram at Fig. 1 A.
In figure:1- conduction contacts, 11- conducting strips, 2- bases, 21- heat emission holes, 22- radiating grooves, 3- connecting bolts, 4- spiral shells Mother, 5- spring steel plates, 6- adjustable springs.
Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below in conjunction with the drawings and specific embodiments into One step is described in detail.
It is as depicted in figs. 1 and 2, a kind of to be applied to high-tension apparatus high-current switch contact, including conductive contact 1 and base 2, The conductive bread of contact 1 three encloses grip base 2, and conductive contact 1 is fixed by fixing device and the phase of base 2.Conductive contact 1 is axe Shape.
Fixing device includes connecting bolt 3 and nut 4, and connecting bolt 3 concatenates the afterbody and base 2 of the conductive both sides of contact 1, Nut 4 is lock onto on connecting bolt 3, so that connecting bolt 3 and nut 4 tense the conductive grip base 2 of contact 1 from both sides. The both ends of connecting bolt 3 are serially connected with spring steel plate 5 and adjustable spring 6, and spring steel plate 5 is affixed on conductive contact 1, and this may be such that Adapt to expand with heat and contract with cold while conductive contact 1 effective grip base 2.Nut 4 and connecting bolt 3 are by non-magnetic stainless steel material system Make.Spring steel plate 5 is by non-magnetic spring steel making.
Conductive contact 1 is laminated bending by more sheets of conductive piece 11 and formed, and the front portion of conductive contact 1 and both sides afterbody are led for multi-disc Electric piece heats integral structure, and the front portion of conductive contact 1 and both sides afterbody are by hot melting process, by the more sheets of conductive piece at this 11 hot melts are integral.Two middle side parts of conductive contact 1 are more sheets of conductive piece split blade type structure, are kept at this between each conducting strip 11 It is independent, therefore laminate characteristics can be retained, the effect being flexible coupling is played, ensures the being adjusted flexibly property and electric conductivity of conductive contact 1, and it is more The individual corporate conductive of conducting strip 11, therefore high current can be born and passed through.The quantity of conducting strip 11 is 60-150 pieces, can tackle high current and lead to Cross.Conducting strip is 0.1mm T2 copper sheets, and electric conductivity is excellent.
