Description
Technical field
The present invention relates to vacuum interrupter field, the vacuum extinction cell structure of specifically a kind of breaker.
Background technology
Vacuum interrupter, also known as vacuum switch tube, are the core components of mesohigh power switch, and its Main Function is to lead to
Crossing the excellent insulating properties of vacuum in pipe makes after mesohigh circuitry cuts power supply that rapid blow-out and electric current can be suppressed, it is to avoid accident and meaning
Outer generation, is mainly used in the transmission ＆ distribution electric control system of electric power.In vacuum interrupter, dynamic and static contact is separately positioned on airtight
In arc-chutes, dynamic and static contact is connected to the conducting rod passed from airtight arc-chutes, is utilized when dynamic and static contact is separated
Vacuum insulation realizes quick blow-out between dynamic and static contact, but when moving contact is acted when being contacted with static contact again, easily deposits
The problem of contact resistance increase caused by deviation is contacted, prior art is usually to set fairlead outside movable contact conducting bar to enter
Row be oriented in case stop, static contact contact deviation, if but occur contact deviation when still cannot be adjusted.
The content of the invention it is an object of the invention to provide a kind of breaker vacuum extinction cell structure, to solve prior art
Dynamic and static contact is due to the big problem of contact resistance caused by contact deviation in vacuum extinction room.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of vacuum extinction cell structure of breaker, it is characterised in that：Including the vertically arranged tubular air-tight casing of central shaft, gas
Close shell upper end nozzle is covered and is connected with static side cover plate, and air-tight casing lower end nozzle is covered and is connected with moved end cover plate, air-tight casing
Inside concentrically axle is provided with shielding cylinder, and ceramic seal head, and upper end ceramic seal head are respectively equipped with air-tight casing upper and lower end nozzle
Bottom, lower end ceramic seal overhead are entered in shielding cylinder corresponding end nozzle by central lug seal plug respectively, static side cover plate
Static side conducting block is provided with, static side conducting block bottom is connected with static side conducting rod vertically, and static side conducting rod lower end sequentially passes through quiet
End casing, upper end ceramic seal head are stretched into shielding cylinder, and static side conducting rod lower end is connected with static contact, vertical in the cover plate of moved end
Slidable fit has moved end conducting rod, and moved end conducting rod lower end passes moved end cover plate and stretches to moved end cover plate lower section, and moved end cover plate bottom
Portion is provided with the fairlead being enclosed within outside the conducting rod of moved end, and moved end conducting rod upper end sequentially passes through moved end cover plate, lower end ceramic seal head
Stretch into shielding cylinder, and moved end conducting rod upper end is connected with moving contact, moving contact side wall is embedded in by annular groove and is provided with annular
Magnet, correspondence moving contact position slip cap is equipped with annular external magnet, and annular internal magnet, annular external magnet on the air-tight casing
Magnetic is attracting.
A kind of vacuum extinction cell structure of described breaker, it is characterised in that：The annular external magnet is airtight by being enclosed within
Ring support support on shell, the moved end conducting rod passes downwards the bottom fixed cover of moved end cover plate equipped with adapter sleeve, ring
Shape frame bottom passes through multiple equally distributed connecting rods of ring and is connected with adapter sleeve sidepiece.
In the present invention, annular internal magnet is embedded in moving contact outer wall, the outer magnetic of annular on annular internal magnet and air-tight casing
Ferromagnetism is attracting, when moved end conducting rod drives moving contact to act, annular is driven simultaneously by adapter sleeve, connecting rod, ring support
External magnet is acted, and so annular internal magnet drives moved end contact action under magnetive attraction effect, therefore by inner and outer annular magnet
Auxiliary moving contact action can be played a part of.When moving contact is contacted with static contact, due to uniform between inner and outer annular magnet
Magnetive attraction is acted on, it is ensured that accurately contacted between dynamic and static contact, if can correct tune under magnetive attraction effect when there is contact deviation
Whole moving contact position, realizes the accurate contact of dynamic and static contact, can effectively reduce the contact resistance between dynamic and static contact.
