Abstract
The utility model discloses an assembly of insulating tension pole for seal poles of high-voltage vacuum breaker comprising a connecting rod (1), an external screw nut (2) and a disc spring (3), wherein the external screw nut (2) and the connecting rod (1) adopts flat surfaces for matching, wherein a slotted hole is arranged on the external nut (2), and two long flat surfaces are arranged on the connecting rod (1). When in assembly, the connecting rod (1) is arranged in an insulating tension pole (4) after traversing through the disc spring (3), the external screw nut (2) is screwed in the insulating tension pole after traversing through the connecting rod (1), which changes the shape of the disc spring (3) and generates the pre-pressure for tightly pressing the connecting rod (1) and tightly rolling the threads between the external nut (2) and the insulating tension pole (4), guarantees no relative motion between the nut and the pole, when rotating the insulating tension pole (4), the torque is transmitted through the external nut (2) and the flat surfaces on the connecting rod (1). The assembly structure satisfies the requirements of small assembly space of the insulating tension pole for seal poles, the assembly saves time and the reliability is high.
Description
Technical field
The utility model relates to the high-pressure vacuum breaker in the electrical power distribution system, and is relevant with the insulated tension pole assembly structure with solid sealing electrode pole of high voltage vacuum breaker especially.
Background technology
In electrical power distribution system, vacuum circuit-breaker adopts compound inslation to reduce overall dimension greatly, and transformer station's floor space is reduced, and has saved land resource; The employing compound inslation has also reduced dust to be assembled on the galvanic circle, thereby has improved the dirty level of resistant of vacuum circuit-breaker.Arc control device mainly are made up of connecting rod, outer nut and dish spring with the insulated tension pole assembling in traditional its pole of compound inslation high-pressure vacuum breaker, and the employing cylinder cooperates with circular hole between connecting rod and the outer nut.Because the pole inner space is little, during assembling, need to be screwed into arc control device to the connecting rod of insulated tension pole fit on earlier, can not transmitting large torque after assembling like this, must adopt specific frock with arc control device and tightly, make connecting rod and arc control device relative to rotating the outer nut on the connecting rod.Simultaneously, this structure torsion to also tight outer nut when assembling is difficult to measure, and can not meet the demands well, makes circuit breaker have great potential safety hazard.
The utility model content
The purpose of this utility model is to design a kind of solid sealing electrode pole of high voltage vacuum breaker easy to assembly to assemble with insulated tension pole.
The utility model solid sealing electrode pole of high voltage vacuum breaker is made up of connecting rod, outer nut and dish spring with the insulated tension pole assembling, and outer nut adopts the plane to cooperate with connecting rod, and outer nut central authorities establish slotted hole, and correspondence position is established two long planes on the connecting rod.
The solid sealing electrode pole of high voltage vacuum breaker that the utility model provides is assemblied between assembling back insulated tension pole and the outer nut with insulated tension pole and rivets, when rotating insulated pull bar, rely on outer nut slotted hole two planes and connecting rod two plane contact, the drive connecting rod rotates, transfer torque, the insulated tension pole assembling is screwed in the vacuum interrupter moving conductive rod, does not need any specific frock just can tighten fast, and can measure tightening torque in the pull bar bottom.Can satisfy the requirement of high-pressure vacuum breaker well, guarantee the reliability that connects, assembling saves time, and is simple and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model solid sealing electrode pole of high voltage vacuum breaker with an embodiment of insulated tension pole assembling;
Fig. 2 is a plan structure schematic diagram embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, connecting rod 2, outer nut 3, dish spring 4, insulated tension pole
As shown in drawings, the utility model solid sealing electrode pole of high voltage vacuum breaker is made up of connecting rod 1, outer nut 2 and dish spring 3 with the insulated tension pole assembling, outer nut 2 adopts the plane to cooperate with connecting rod 1, is provided with slotted hole on outer nut 2, and connecting rod 1 is provided with two long planes.
During assembling, dish spring 3 is placed in the insulated tension pole 4, connecting rod 1 passes dish spring 3 endoporus, and outer nut 2 slotted holes are enclosed within 1 liang of plane one end of connecting rod, are screwed into then in the insulated tension pole 4, make dish spring 3 produce certain deformation and produce precompression, insulated tension pole 4 and outer nut 2 screw threads are crushed to death, stop outer nut 2 to rotate, when rotating insulated tension pole 4 relative to insulated tension pole 4, rely on outer nut 2 central two planes and the connecting rod 1 two planes carry-over moment each other, drive connecting rod 1 and rotate synchronously together and tighten.
