Abstract
The present invention relates to a kind of electrical contact, including contact, fingertip, spring, it is soft in flakes, right conductive arm, bracket, nut, bolt, left conductive arm.Left conductive arm is equipped with contact, and contact two sides are equipped with fingertip, are respectively equipped with spring on fingertip, spring is equipped with nut, between fingertip by bolt crimp it is soft in flakes, the soft bracket that passes through in flakes is connect with right conductive arm, it is soft in flakes with a thickness of 5mm, the diameter of bolt end is 2mm.The present invention solves and contacts bad, easily fever between switch contact and fingertip, and the vulnerable problem of spring, materials save 50% or so compared with traditional structure, and accuracy of manufacture reduction, part processing capacity is reduced, and performance is improved.
Description
Technical field
The present invention relates to a kind of switches, and in particular to a kind of electrical contact.
Background technique
Disconnecting switch is the high-tension switch gear in power grid power transmission and transforming equipment, is that usage amount is maximum in electric system, applies
Product widest in area makes disconnecting switch problem relatively more for various reasons, and failure happens occasionally.According to State Grid Corporation of China's tune
Display is looked into, the operational reliability of the disconnecting switch without improvement transformation of old-fashioned structure is away from the requirement of existing power grid high reliability
It differs greatly, the safe operation of power grid is affected greatly, high voltage isolator overheat of conducting circuit is to fail for a long time
Thoroughly solve the problems, such as.According to current operating experience, the operating current of most of disconnecting switch can only generally use its specified work
Make 60% or so of electric current, if it exceeds 70% may overheat.Electrical contact is a critical component of disconnecting switch,
It directly takes on dividing, closing for circuit, and the electric current in circuit passes to the other end from one end, is made of multiple components, other components one
As all to be fixedly connected, and electrical contact is not capable of fixing then, it is necessary to be activity, can free division, so it is just at entirely leading
The weak link of electrical circuit guarantees its reliably working, increases difficulty due to the particularity of its present position and effect.Mesh
Preceding using more traditional electrical contact structure is placed the spring among two fingertips, there is shunting function during the energization,
Lead to its fever, failure, such fingertip just looses elastic force, it cannot be guaranteed that being in close contact, causes security risk.
Summary of the invention
The purpose of the present invention is to provide a kind of contacts well, is not easy the electrical contact to generate heat.This is practical
It is novel to be achieved through the following technical solutions: including contact, fingertip, spring, it is soft in flakes, right conductive arm, bracket, spiral shell
Mother, bolt, left conductive arm.Left conductive arm is equipped with contact, and contact two sides are equipped with fingertip, are respectively equipped with spring, spring on fingertip
Be equipped with nut, between fingertip by bolt crimp it is soft in flakes, the soft bracket that passes through in flakes is connect with right conductive arm, soft thickness in flakes
Degree is 5mm, and the diameter of bolt end is 2mm.
Compared with the prior art, the present invention has the following beneficial effects: spring is placed on the outside of two fingertips, work is not shunted
With, and radiate preferably, spring is not easy to generate heat and fail, and guarantees to be in close contact, and can adjust spring pressure by M6 nut.
Increasing soft water conservancy diversion cross section in flakes, thickness reaches 5mm, and is crimped with fingertip using M8 bolt, and bonding strength is high, it is not easy to loosen,
It is easy to maintenance, guarantee that electric current passes through.By bolt vehicle at the small boss of a diameter 2mm, a fulcrum is constituted with bracket, it and touching
The contact position of head and fingertip forms a triangle projective planum, so will not generate to contact and fingertip contact position any dry herein
It disturbs, all foozles, which are all accumulated, to be arrived herein, and is herein a dot floating support, and not conductive by it, this is ensured that
Contact and the comprehensive engagement always of fingertip contact position, increase the water conservancy diversion reliability of entire contact.It is soft logical with right conductive arm in flakes
Bracket compression is crossed, guarantees to be in close contact.Outdoor high-voltage alternating current electrical contact materials save 50% or so than traditional structure, and make to make
Manufacturing accuracy reduces, and part processing capacity is reduced, and performance is improved, and not only improving reduces cost, and is conducive to tissue production.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
It include contact 1, fingertip 2, spring 3, soft 4, right conductive arm 5, bracket 6, nut 7, spiral shell in flakes referring to Fig. 1 present invention
Bolt 8, left conductive arm 9.Left conductive arm 9 is equipped with contact 1, and 1 two sides of contact are equipped with fingertip 2, are respectively equipped with spring 3, bullet on fingertip 2
Spring 3 is placed on the outside of two fingertips, without shunting function, and is radiated preferably, and spring is not easy to generate heat and fail, and guarantees to be in close contact,
The adjustable spring pressure of M6 nut 7 that spring 3 is equipped with.Soft in flakes 4 are crimped by M8 bolt 8 between fingertip 2, connection is strong
Degree is high, is not easy to loosen, easy to maintenance, guarantees that electric current passes through, and by 8 vehicle of bolt at the small boss of a diameter 2mm, with bracket
6 constitute a fulcrum, one triangle projective planum of contact position formation of it and contact 1 and fingertip 2, so herein will not be to contact 1
Any interference is generated with 2 contact position of fingertip, all foozles, which are all accumulated, to be arrived herein, and is herein one small point floating branch
It holds, not conductive by it, this guarantees contacts 1 and the comprehensive engagement always of 2 contact position of fingertip, increase leading for entire contact
Flow reliability.It is soft 4 to be compressed in flakes with right conductive arm 5 by bracket 6, guarantee to be in close contact.It is soft in flakes 4 with a thickness of 5mm, bolt
8 diameter is 2mm.
