Abstract

A radial compensating busbar for high-pressure switches belongs to the technical field of high voltage electrical apparatus and comprises three identical-structure groups of conductive elements, a connecting piece, two basin type insulators connected with the connecting piece, two corrugation pipes and a casing. A first basin type insulator and a first corrugation pipe as well as a second basin type insulator and a second corrugation pipe are respectively fixedly arranged at two ends of the casing. Two ends of a first conductive component, two ends of a second conductive component and two ends of a third conductive component are respectively fixedly connected with the first basin type insulator and the second basin insulator which are arranged at the two ends of the casing. The conductive components are sealed inside the casing. The radial compensating busbar for high-pressure switches satisfies compensations of axial deformation and radial deformation in gas insulated and metal enclosed switchgear (GIS), regulation of installation errors and compensation of self expansion and contraction transformation of the busbar. Additionally, the compensation dosage of the radial compensation is large, and good performance of electrical equipment can be maintained.

Background technology
Bus is as the element that compiles, distributes and transmit electric energy, it is indispensable part in the high voltage electric appliance, and major part all can not be born the stress of radial deformation in the bus of using in High-Voltage Electrical Appliances, but when high voltage electric appliance connects or because the sedimentation of ground etc. are former thereby difference in height inevitably occurs, the radial compensation bus arises at the historic moment like this.
Find through retrieval prior art, Chinese patent literature CN2610476, put down in writing a kind of " bus structure of power source conversion isolating switch ", this technology comprises load bus (1), stand-by power supply bus (2), main power source bus (4), moving contact (3) (7), fixed contact (5), it is characterized in that adopting moving contact (3), (7) to be connected on stand-by power supply bus (2) and the power source bus (4), fixed contact is fixed on the load bus (1).Housing in this technology is connected the effect of playing nose balance with a bellows, and such structure can satisfy connection request generally speaking, but can not realize adjusting when the distortion of radial direction appears in the bus both sides, causes system to go wrong.And the cold and hot distortion of self also can cause the basis, both sides to bear bigger active force.
The utility model content
The utility model is at the prior art above shortcomings, a kind of radial compensation bus that is used for high-voltage switch gear is provided, satisfy in the GIS gas-insulated metal enclosed switchgear axially and radial deformation compensates and alignment error is adjusted and can the distortion of expanding with heat and contract with cold of bus self be compensated, and greatly also can keep electric property good to the compensation rate of radially distortion.
The utility model is achieved through the following technical solutions, the utility model comprises: the conductive component of three groups of same structures, connector and two coupled disc insulators, two bellowss and housing, wherein: first disc insulator and first bellows and second disc insulator and second bellows are fixedly set in the two ends of housing respectively, first conductive component, fixedly connected with second disc insulator with first disc insulator that is positioned at the housing two ends respectively in the two ends of second conductive component and the 3rd conductive component, described conductive component sealing is arranged at enclosure interior.
The end of described connector is provided with spheric washer and taper faced washer;
Described conductive component comprises: contact, short conductors and long conductor, wherein: an end and the short conductors of long conductor are connected in series, the other end of long conductor and contact socket connection, the other end of contact and short conductors are fixedly set in respectively on first disc insulator and second disc insulator.
Described contact is provided with conductor block, in the conductor block outside radome is arranged, uniform some plum blossom fingertips in the radome, and described contact is by plum blossom fingertip and long conductor socket connection.
The center of described conductor block is provided with the guide blot that is used to peg graft.
Disc insulator, bellows, housing are tightly connected by bolt connection piece in the utility model, this overall absorption deflection that expands with heat and contract with cold, and carry out spacing to the axis deformation of whole bus.Use a plurality of bellowss can increase the compensation rate that bus is connected the two ends radial deformation.Contact adopts Mume flower contact, and this contact bounce amount is big, can not cause very big stress to conductor when bus generation radial deformation, conductor is played a protective role the adjustment of inner conductor in the time of can satisfying axial deformation again.
