Technical field:
The present invention relates to the electric installation on a kind of controller switching equipment, relate in particular to a kind of electric installation that outdoor high-voltage alternating current isolating switch is used that is used for.
Background technology
High-voltage alternating current isolating switch in the electric power system mainly acts on: can pass through rated current for a long time during combined floodgate, be that circuit improves obvious visible isolation fracture, easy access and protection during separating brake.Product is according to the characteristics of motion, isolating switches such as collapsible, horizontal rotation type and vertical opening type are arranged on structure model selection, motion by conductive seat when their main movement characteristic is divide-shut brake drives the contact tube action, make contact tube be in separating brake or closing position, wherein folding isolating switch, jackknife action when moving by contact tube can reduce this overall dimension when sub-gate position is put, and reaches the little purpose that takes up room.Between product contact tube and contact tube, all can need so a kind of can move simultaneously can also be through-flow structure, it is many to adopt conductive strips to add the form of mechanical transmission structure traditionally, it has simple in structure, reliable characteristics.But because overall dimension is big, the conductive strips long term exposure is in atmospheric environment, so its outward appearance is not attractive in appearance and antiseptic property is poor.
The inventor had once disclosed a kind of contact tube of high voltage isolator and the arrangements of electric connection of contact tube in application number is 200710189751.2 patent application, it has good Motion Transmission function and conducting function, and compact conformation also has fine antiseptic power.But the last contact tube in this conductive connecting device is to fixedly connected with end cap; In order to guarantee product quality and assembling effect, the filler of packing into again in the last contact tube, this has not only increased the quantity of parts in the product, increase trouble to assembly work, and because the conduction connection ring joint is more, increased heating position, therefore can influence the stability of this device performance, also can reduce useful life.
Summary of the invention
The purpose of this invention is to provide a kind ofly, the link that connects of being difficult for being corroded, conducting electricity is few, more compact structure, conducting function and Motion Transmission functional effect are better, and the arrangements of electric connection that is used for outdoor high-voltage isolating switch of long service life
To achieve these goals, the present invention adopts following technical scheme: the arrangements of electric connection of this outdoor high-voltage isolating switch, comprise: following contact tube, last contact tube, following contact tube is fixedlyed connected with axle bed, axle sleeve is positioned at the outside of axle bed, be provided with an insulating support in the axle sleeve, through hole is arranged on the insulating support, insulating bushing and spring are housed in the through hole, and it is corresponding with a ball fingertip, ball fingertip and bearing are equipped with end cap on the end of axle sleeve away from following contact tube between the inwall and axle bed outer wall of axle sleeve, conductor and axle sleeve are solidified as a whole, conductor is contained in the contact tube, and both are bolted to connection.
Described conductor is cylindrical, and the internal diameter size of its outside dimension and last contact tube is complementary.
On the outer wall of described conductor column shape cannelure is arranged.
The axle bed outer wall has a taper seat, and it contacts with the ball fingertip.
Described bearing is the deep groove ball bearing of band sealing ring.
Be provided with back-up block in the following contact tube.
Described insulating support one end is cylindrical, has three through holes on end face at least, between every adjacent through hole boss is arranged.
Following contact tube is fixedlyed connected with axle bed by bolt, and end cap is fixedlyed connected with axle sleeve by bolt.
There are six or eight through holes at the cylindrical portion place of described insulating support one end, and described ball fingertip also is six or eight.
Between the contact-making surface of end cap and axle sleeve, be provided with sealing ring.
Between the outer wall of the axle bed of fixedlying connected with following contact tube 1 among the present invention and the inwall of axle sleeve ball fingertip and bearing are arranged, not only guaranteed the reliability of relative motion between last contact tube and the following contact tube, and realized the reliability that electric energy transmits between them.Because the ball fingertip is arranged in the structure of sealing, has increased the dust tightness and the anti-corrosive properties of product.Because the dynamic transfer system of this arrangements of electric connection is followed successively by down contact tube → axle bed → bearing → axle sleeve → last contact tube; Conducting system is followed successively by down contact tube → axle bed → ball fingertip → axle sleeve → last contact tube.And conductor among the present invention and axle sleeve are solidified as a whole, and conductor is contained in the contact tube, actual is that axle sleeve directly is connected with last contact tube, and this structure makes that the present invention is that the Motion Transmission function and the conducting function effect of the arrangements of electric connection of the sort of end cap and last contact tube fixed connection structure form in 200710189751.2 the patent application is better than application number.Conduction connection ring joint of the present invention in addition is less, has reduced heating position, makes this device performance more stable, has also increased useful life.
