Description
Technical field
The present invention relates to a kind of contacts for vacuum-break switches.
Background technology
Utilize vacuum to be called vacuum circuit-breaker as the circuit breaker of insulation between contact and arc-extinguishing medium.The insulation crust of vacuum circuit-breaker arc control device is made by glass or pottery, the moving contact that is provided with fixing fixed contact in the insulation crust and controlled by operating mechanism, and the sealing during the moving contact motion is by bellows.Bellows is flexible in the regime of elastic deformation that allows, and arranged sufficiently high mechanical endurance.The vacuum circuit-breaker of this structure, moving contact because of minute, feed motion moves, fixed contact is fixed, in the making process, the moving contact fixed contact that can clash produces very big strike note, between contact, produce spring, cause the excessive scaling loss and the wearing and tearing of contact.
Summary of the invention
The purpose of this invention is to provide a kind of impact between the contact, little contacts for vacuum-break switches of shellproof breaker tripping and closing noise alleviated.
For achieving the above object, the present invention adopts following technical scheme:
A kind of contacts for vacuum-break switches of the present invention comprises moving contact and fixed contact, and moving contact is inserted on the moving contact end cap of insulation crust one side, is connected with the telescopic that plays sealing function between moving contact and the moving contact end cap; Fixed contact is connected the inboard of the fixed contact end cap of opposite side, it is characterized in that: the fixed contact output shaft fixedly is inserted into stationary contact and covers, the end that the fixed contact output shaft is positioned at insulation crust is fixedly connected with sliding contact, sliding contact is the pipe shape, the one end has the screw thread that is connected with the fixed contact output shaft, the inwall of the other end has sliding contact, has supporting bracket between the screw thread of sliding contact and the sliding contact, and the centre of supporting bracket has installing hole; Fixed contact is inserted in the sliding contact, cylindrical fixed contact conducting rod, fixed contact guide post that fixed contact comprises fixed contact, links into an integrated entity with fixed contact, the diameter of fixed contact conducting rod and the internal diameter of sliding contact adapt, the fixed contact guide post is inserted in the installing hole on the supporting bracket, and locks with lock pin; Between fixed contact conducting rod and supporting bracket, be provided with steel sheet spring.
After adopting technique scheme, fixed contact floats and is connected stationary contact and covers, and can effectively alleviate switch on of moving contact and impact, and prevents spring, prolongs contact and sends out useful life, reduces noise.
Description of drawings
Accompanying drawing is the structural representation of one embodiment of the invention.
Embodiment
As shown in drawings, a kind of contacts for vacuum-break switches of the present invention comprises moving contact 1 and fixed contact, and moving contact 1 and fixed contact all are installed in the vacuum chamber that is made of insulation crust 3.The two ends of insulation crust 3 are respectively moving contact end cap 31 and fixed contact end cap 32.Moving contact 1 is inserted on the moving contact end cap 31 of insulation crust 3 one sides, is connected with the telescopic 11 that plays sealing function between moving contact 1 and the moving contact end cap 31; Fixed contact 2 is connected the inboard of fixed contact end cap 32.Fixed contact output shaft 4 fixedly is inserted on the fixed contact end cap 32, can adopt welding also can adopt the mode that is threaded, as long as guarantee good seal.The end that fixed contact output shaft 4 is positioned at insulation crust 3 is fixedly connected with sliding contact 5 by screw thread, sliding contact 5 is the pipe shape, the one end has the screw thread that is connected with fixed contact output shaft 4, the inwall of the other end has sliding contact 51, have supporting bracket 52 between the screw thread of sliding contact 5 and the sliding contact 51, the centre of supporting bracket 52 has installing hole; Fixed contact is inserted in the sliding contact 5.Cylindrical fixed contact conducting rod 2A, fixed contact guide post 2B that fixed contact comprises fixed contact 2, links into an integrated entity with fixed contact 2, the diameter of fixed contact conducting rod 2A and the internal diameter of sliding contact 51 adapt, fixed contact guide post 2B is inserted in the installing hole on the supporting bracket 52, and locks with lock pin 2C; Between fixed contact conducting rod 2A and supporting bracket 52, be provided with steel sheet spring 22.
When closing a floodgate, moving contact 1 moves to the fixed contact direction rapidly under the effect of driving mechanism, when moving contact 1 with after fixed contact contact, fixed contact is squeezed, slip in sliding contact 5, steel sheet spring 22 is compressed, and plays cushioning effect, the minimizing impulsive force.Can reduce the noise that moving contact and fixed contact contact-impact produce like this, can also prolong the useful life of contact simultaneously, avoid moving contact to produce spring, reduce electrical arc erosion degree between moving contact and the fixed contact.
Separating brake at first, steel sheet spring 22 promotes fixed contacts and moving contact 1 moves together, helps to improve just-off speed.
