Description
Technical field:
The present invention relates to a kind of arrangements of electric connection that 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, 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 simple in structure, reliable characteristics.But because overall dimension is big, the conductive strips long term exposure also has himself shortcoming in atmospheric environment, such as not attractive in appearance and antiseptic property difference etc.
The conductive connecting device that the purpose of this invention is to provide a kind of reliability height, compact conformation, is difficult for being corroded; And this device can be used in the high-voltage alternating current isolating switch product of various structural shapes.
To achieve these goals, the present invention adopts following technical scheme: the arrangements of electric connection that this high voltage isolator is used, comprise the conductive seat, the contact tube that are enclosed within on the power transmission shaft, one end of conductive seat, conductive shield, cover plate and an end of connecting lever are housed on power transmission shaft successively, wherein conductive seat is fixedlyed connected with conductive seat, conductive shield contacts with conductive seat by the ball fingertip, cover plate is fixedlyed connected with conductive shield, the other end of cover plate and the other end of connecting lever lay respectively at the both sides of contact tube, and all fixedly connected with contact tube.Equally distributed hole is arranged on conductive shield, insulating bushing is all arranged in each hole, be provided with spring and a described ball fingertip in the insulating bushing, and described ball fingertip is between conductive seat and conductive shield inwall.In contact tube, be provided with filler.
Be connected for key between power transmission shaft and the connecting lever.
The upper end of conductive seat is conical, disconnected for cylindrical down.
Between the cylindrical outer wall of the port of conductive shield and conductive seat, be provided with sealing ring.
Power transmission shaft is fixedlyed connected with connecting lever in the present invention, the other end of connecting lever is fixedlyed connected with contact tube again becomes transmission mechanism in this device, the conductive seat that is enclosed within on the power transmission shaft and is connected successively with conductive seat, ball fingertip, conductive shield, cover plate and the contact tube of fixedlying connected with the other end of cover plate become the conductive mechanism of the activity of this device again, and adopted the ball fingertip as having the motion of relative motion part and through-flow connector, therefore the through-current capability of this device is strong, the reliability height is so can be used in the high-voltage alternating current isolating switch product of various structural shapes; All component in this device interconnects closely, structure is very compact, and assembly is less than situation exposed in atmospheric environment, if the inside of adopting the sealing ring sealing can also prevent dust storm and rainwater access to plant again, so this device is difficult for being corroded, has the advantage of long service life.
Description of drawings:
Fig. 1 is a structure chart of the present invention;
Fig. 2 is the front view of conductive shield among the present invention;
Fig. 3 is that the A-A of Fig. 2 is to view.
Embodiment:
The arrangements of electric connection that this high voltage isolator is used, comprise conductive seat 1 and contact tube 8, conductive seat 1 is sleeved on the power transmission shaft 2, one end of conductive seat 11, conductive shield 9, cover plate 4 and an end of connecting lever 3 also are housed on power transmission shaft 2 successively, and wherein conductive seat 1 and conductive seat 11 are fixed together them by bolt; The top of conductive seat 11 is cylindrical for conical, bottom.Eight identical equally distributed holes 14 of size are arranged on the conductive shield 9, in each hole 14 insulating bushing 6 is arranged all, be provided with spring 5 and a ball fingertip 7 in the insulating bushing 6; And ball fingertip 7 makes conductive shield 9 contact with conductive seat 11 by ball fingertip 7 between conductive seat 11 and conductive shield 9 inwalls; One end of cover plate 4 is fixedlyed connected with conductive shield 9 by bolt, and the other end of another of cover plate 4 and connecting lever 3 lays respectively at the both sides of contact tube 8, by bolt they and contact tube 8 is fixed together.In contact tube 8, be provided with filler 12, to prevent contact tube 8 distortion.
For the ball fingertip 7 in the hole can be contacted with conductive seat 11 again with the 9 contacted whiles of conductive shield, one end of conductive shield 9 has an axial notch, make hole 14 become cylinder in half, guaranteed that like this electric current interconnects between conductive shield and conductive seat 11 by ball fingertip 7 at this position.
In order to prevent that dust storm and rainwater from entering fingertip inside, make structure have good antiseptic property, between the cylindrical outer wall of the port of conductive shield 9 and conductive seat 11, be provided with sealing ring 10.More stable for what sealing ring 10 was combined with parts, can by the port position of groove one end seal groove 9b be set at conductive shield 9, sealing ring 10 is packed in this groove.Can adopt key to be connected or other friction tight version between one end of connecting lever 3 and the power transmission shaft 2.
Fixedlying connected between fixedlying connected between conductive seat 1 and the conductive seat 11, cover plate 4 and the conductive shield 9 also can be adopted pin or other form that is connected.
In contact tube 8, also filler can be set, should note firmly situation when contact tube 8 is assembled together with cover plate 4 and connecting lever 3 in this case.
Operation principle of the present invention is: electric current is by the conductive seat that links to each other with the fingertip seat, and the conducting system by the conduction joint passes to the following contact tube that links to each other with cover plate.Motion is passed to coupled following contact tube then by power transmission shaft by connecting lever, realizes the branch resultant motion of contact tube.Between fingertip seat and the conductive seat, by being fixedly linked, guarantee through-flow reliability between cover plate and the contact tube.
