The invention discloses an annular rotating pole type vacuum switch. An incoming line static contact, an outgoing line static contact and an earthed static contact are distributed on an annular insulated frame; a rotating pivot of the rotating pole is arranged in the annular center of the annular insulated frame and rotates along an annular ring of the annular insulated frame; the rotating pole consists of a vacuum extinction chamber and a copper conductor connected with the vacuum extinction chamber; movable contacts are respectively arranged at the end parts; and in the rotating process, the two movable contacts of the rotating pole are respectively spliced with the incoming line static contact, the outgoing line static contact and the earthed static contact which are arranged on the annular insulated frame. In the structure, the rotating pole with the vacuum extinction chamber is used to rotate to different positions to correspondingly match with the closing or breaking of the vacuum extinction chamber, the invention realizes the separation, the closing, the isolation and the earthing of the switch and creates a switch element with a compound function.
Description
Technical field
The present invention relates to the vacuum switch field in the switchgear of electric power in passing on, control, protecting, relate in particular to the dielectric of vacuum as arc extinguishing, be widely used in the annular rotating pole type vacuum switch of electric power system.
Background technology
In middle pressure (3～35kV electric pressure) switchgear field, vacuum switch with its have volume little, do not explode, do not burn, with the characteristic of eco-friendly excellence, in the application of switchgear, occupy an leading position, and will more and more widely be applied to electric power system.Existing vacuum switch form both domestic and external is varied, but has only " combined floodgate " (connection circuit) and two kinds of functions of " separating brake " (open circuit) of switch usually.For " isolation " (will load with power supply effectively isolate, have obvious isolation fracture) and " ground connection " (ground connection of will loading, with the plan personal safety), must install isolating switch additional and close splice grafting ground switch, form " combined electrical apparatus " that has " combined floodgate ", " separating brake ", " isolation " and " ground connection " function or claimed " compound electric apparatus "." combined electric appliance " or " combined type electrical equipment " that this class is pieced together type with several switch elements is bulky, inconvenience is taken a lot of work, used to complex structure, consumptive material.
Summary of the invention
The present invention proposes be one simple in structure, volume is little, has the annular rotating pole type vacuum switch of " combined floodgate ", " separating brake ", " isolation " and " ground connection " function simultaneously.
The present invention is by the following technical solutions: vacuum switch comprises annular Insulating frame, inlet wire fixed contact wherein, outlet fixed contact and ground connection fixed contact are distributed on the annular Insulating frame, the pivot point of rotation pole is located at the annular center of annular Insulating frame, and along the rotation of the annular ring of annular Insulating frame, the rotation pole is made up of vacuum interrupter and coupled copper conductor, the end of vacuum interrupter and coupled copper conductor respectively is provided with moving contact, angle and inlet wire fixed contact that two moving contacts and fulcrum form, angle and outlet fixed contact that the annular center of outlet fixed contact and annular Insulating frame forms, the ground connection fixed contact equates with the angle that the annular center of annular Insulating frame forms, in the rotation pole rotary course, its two moving contact respectively with annular Insulating frame on the inlet wire fixed contact, outlet fixed contact and ground connection fixed contact are pegged graft.
Above-mentioned annular Insulating frame is provided with isolating points, in the moving contact rotary course of rotation on the pole with its grafting.
The inwall of above-mentioned annular Insulating frame is cylindrical for sealing, and its outer rim can shape not limit.
The present invention adopts above technical scheme, and the vacuum interrupter on the utilization rotation pole and the moving contact of copper conductor are pegged graft with inlet wire fixed contact, outlet fixed contact and ground connection fixed contact respectively.Inlet wire, outlet fixed contact plug on two moving contact and annular Insulating frame on the rotation pole, and when vacuum interrupter was in " cut-offfing ", switch was in gate-dividing state, the circuit access failure; When the vacuum arc control device were in " close the pass ", switch was in "on" position, had connected the circuit of power supply and load; " cut-off " vacuum interrupter, be rotated counterclockwise the rotation pole, moving contact on the rotation pole separates with the fixed contact on the Insulating frame, realize the isolation of inlet wire, outlet, switch is in isolation, except visible up and down two fractures, vacuum extinction is indoor to also have a sightless fracture, and three fractures have guaranteed the reliability of vacuum switch " isolation "; Continue to be rotated counterclockwise the rotation pole, moving contact on the rotation pole and the outlet on the annular Insulating frame and ground connection fixed contact plug, " close the pass " vacuum interrupter, and load is connected with the circuit of ground connection, switch is in ground state, and switch is more reliable by the splice grafting ground, pass of vacuum interrupter.So vacuum switch is realized a process from combined floodgate, separating brake, isolation to ground connection, the rotation pole that turns clockwise equally, namely realize switch from ground connection, isolation, separating brake to making process.This is simple in structure, is a switch element with complex function.
