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, makes contact tube be in separating brake or closing position.Jockey between product conductive seat and contact tube can either be realized motor function like this, also has good through-flow characteristic again simultaneously.Version in the past is to adopt conductive strips to add mechanical transmission structure mostly, and it has reliable characteristics.But because overall dimension is big, the conductive strips long term exposure also has himself shortcoming in atmospheric environment, so antiseptic property is poor, and profile is not attractive in appearance yet.
The applicant had once disclosed the arrangements of electric connection that a kind of high voltage isolator is used in application number is 200710189768.8 patent application, this conductive connecting device has good Motion Transmission function and conducting function, also have attractive in appearance and fine antiseptic power, but because the parts that conduction connects are more, the contact-making surface of electric-conductor is increased, therefore the chance of heating also increases, and this can influence to some extent to the useful life of conductive connecting device; In addition in 200710189768.8 patent application, contact tube in the arrangements of electric connection is between the other end of the other end of cover plate and connecting lever, they are fixed together jointly, and the filler of will packing in contact tube generally speaking is in order to guarantee product quality and assembling effect; The filler of will packing in contact tube, this has not only increased the quantity of parts in the product, and has increased trouble to assembly work.
Summary of the invention:
The purpose of this invention is to provide a kind ofly, the arrangements of electric connection that the link that connects of being difficult for being corroded, conducting electricity is few, more compact structure, conducting function and Motion Transmission functional effect better are used for high voltage isolator
The objective of the invention is to adopt following technical scheme to realize: this arrangements of electric connection that is used for high voltage isolator, comprise contact tube, be sleeved on the conductive seat on the power transmission shaft, one end of one end, cover plate and the connecting lever of fingertip seat, conductive shield also is housed on power transmission shaft successively, wherein conductive seat is fixedlyed connected with the fingertip seat, one end of conductive shield contacts with the fingertip seat by the ball fingertip, cover plate is fixedlyed connected with an end of conductive shield, the other end of conductive shield inserts in the contact tube, and it is fixedlyed connected with the other end of connecting lever by bolt jointly with contact tube.
One end of conductive shield has a through hole, and this through hole is positioned at this end centre, and it is contained on the power transmission shaft, and the outside dimension of its internal diameter and power transmission shaft is complementary; The other end of conductive shield is a cylinder, and the internal diameter size of this cylindrical external diameter and contact tube is complementary, and the longitudinal center line of through hole is perpendicular on cylindrical longitudinal center line of the conductive shield other end and conductive shield one end.
Also have equally distributed hole on conductive shield, insulating bushing is all arranged in each hole, be provided with spring and a ball fingertip in the insulating bushing, the ball fingertip is also between fingertip seat outer wall and conductive shield inwall.
Between cover plate and power transmission shaft, be provided with O-ring seals
The top of fingertip seat is cylindrical for conical, bottom.
Between the cylindrical outer wall of the bottom of conductive shield one end and fingertip seat, be provided with sealing ring.
Be connected for key between power transmission shaft and the connecting lever.
Because in the arrangements of electric connection of high voltage isolator, conductive shield and contact tube all play electric action, the end with conductive shield among the present invention directly inserts in the contact tube, and they are bolted to connection jointly, has reduced the conduction link; Therefore this arrangements of electric connection is better than the arrangements of electric connection electric conductivity that the inventor discloses in 200710189768.8 patent application; Because 200710189768.8 patent application and the present invention have adopted the drive system that drives contact tube with connecting lever, and structure of the present invention to be a end with conductive shield directly insert in the contact tube, be convenient to the power transmission, more help the branch resultant motion of contact tube.The other end of conductive shield inserts in the contact tube in this device in addition, reduced the assembly of this device, its structure is very compact, not only be convenient to the assembling of product, and the position of having reduced the conducting connecting part contact, reduced the chance of generating heat, make conducting function and Motion Transmission functional effect better, in addition this device be with the ball fingertip as conducting system with relative motion, can effectively realize the conduction and the transmission agency of isolation switch device; And the ball fingertip is arranged in the structure of sealing, has prevented that effectively dust storm and rainwater from entering fingertip inside, has guaranteed that conducting system is difficult for being corroded; Make the life-span of product longer.
