Abstract
The utility model discloses a vacuum switch with isolated break, higher insulation level and small volume, which can avoid total recovery voltage when a vacuum arc-extinguishing chamber bears breaking or switching. The vacuum switch with isolated break is characterized in that an isolation break is arranged between an incoming line end and a vacuum break; the incoming and the outgoing line end are designed with insulating sleeves. The inside of a box body is designed with distant insulating partition boards and is filled with insulating gas. The structure of a connecting rod mechanism and a sliding board crank arm mechanism linked on the main shaft of an operating mechanism ensures the electric requirements of firstly switching on and finally switching off the isolated break, and finally switching on and firstly switching off the vacuum break; consequently the occurrence of re-breakdown phenomenon caused by the decrease of the insulating strength of medium.
Description
Vacuum switch with isolation fracture.
The utility model relates to a kind of distribution line switchgear, particularly has the vacuum switch of isolation fracture.
When existing vacuum switch uses, born full recovery voltage at breaking current final vacuum arc control device, dielectric can not very fast recovery sufficient intensity and often cause insulation level to descend, even re-breakdown phenomenon occurs; And the existing dielectric strength of vacuum switch in order to guarantee that vacuum extinction is outdoor generally is filled with transformer oil or do not inflate at outdoor box, therefore seems that weight is higher, and volume is bigger.This shows that design and a kind ofly avoid vacuum interrupter to bear disjunction or full recovery voltage when closing a floodgate, the vacuum switch that insulation level is higher and volume is less is necessary.
The purpose of this utility model is to design a kind ofly can avoid vacuum interrupter to bear disjunction or the full recovery voltage when closing a floodgate, the vacuum switch with isolation fracture that insulation level is higher and volume is little.
The technical solution of the utility model is a kind of vacuum switch of being made up of end of incoming cables, casing, vacuum fracture, leading-out terminal, it is characterized in that design has isolation fracture between end of incoming cables and the vacuum fracture, into and out of the line end design insulating case is arranged, the box house design has the phase insulation dividing plate between each electric phase also insulation gas filled; The conducting rod of end of incoming cables is fixed with the quiet disconnecting link of isolation fracture through connecting piece, quiet disconnecting link is combined with link joint in the moving knife lock of isolating on the axle, the noncontact end of moving knife lock is on the soft moved end that is connected in the vacuum fracture in succession, the linkage that the operating mechanism main shaft is connecting on the isolation beam warp insulating part of isolation fracture and the other end and the casing connects mutually, the operating mechanism main shaft also is linked with slide plate, the chute of slide plate is built-in with the connecting lever that the other end is linked in vacuum shaft, and vacuum shaft is also connecting the insulation arm of being made by insulating material on the moved end that the other end is fixed in the vacuum fracture.When the operating mechanism main shaft turns over a bigger angle clockwise, during as 35 °, drive the isolation axle by linkage and rotate, order about the moving knife lock that is linked on this and close with the quiet disconnecting link that matches; Meanwhile, the operating mechanism main shaft orders about the slide plate that is connecting and rotates, and as below motion left, but the chute shape of this process middle slide plate causes the connecting lever that places chute to keep static.When the operating mechanism main shaft continues to turn over a less angle, during as 5 °～8 °, the moving knife lock of isolation fracture is fully contacted with quiet disconnecting link through the effect of linkage; Meanwhile, order about connecting lever through the chute of slide plate and rotate, rotate as clockwise direction, drive the vacuum shaft that the connecting lever other end connecting and rotate, the rotation of vacuum shaft is ordered about the moved end of vacuum fracture and is closed a floodgate mutually with quiet end through insulation arm.The process that aforesaid operations closes a floodgate has reached must close earlier when the utility model does to close a floodgate the action isolation fracture and then the electric requirement of the vacuum fracture that closes; Obviously, the utility model is done separating brake when action, must first disjunction vacuum fracture, and then the disjunction isolation fracture.So just guaranteed all to be added on the vacuum fracture again, thereby avoided the re-breakdown phenomenon that causes because of the decline of medium dielectric strength at the full recovery voltage that closes a floodgate and form during disjunction.
The vacuum switch that the utility model obtains after implementing with isolation fracture, practical probation through relevant electrical power trans mission/distribution system shows to have following advantage: 1, the medium dielectric strength of having avoided existing vacuum switch to cause because the vacuum fracture bears full recovery voltage descends the appearance of having stopped re-breakdown phenomenon; 2, owing to increasing insulating case on line terminals, each electricly alternately is provided with the phase insulation dividing plate in casing, and insulation gas filled, as N
2, SF
6Gas, thus it is less to have obtained the box house volume when guaranteeing higher insulation level, thereby little, the lightweight effect of whole volume of switch.Not only can be installed on electric substation in actual use, also can be installed on the distribution bar of distribution route, cooperate with control device to can be used as circuit breaker, sectionalizer, automatic circuit and automatic distribution switch.
