Description
Technical field
The utility model is related 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 out of 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 to when being contacted with static contact again, easily deposits
The problem of contact resistance increases caused by contacting deviation, prior art is usually to set guide sleeve to enter outside movable contact conducting bar
Row is oriented to prevent stop, static contact contact deviation, if but occurring still not being adjusted during contact deviation.
Utility model content the purpose of this utility model is to provide a kind of vacuum extinction cell structure of breaker, to solve
Dynamic and static contact is due to the problem of contact resistance is big caused by contact deviation in prior art vacuum extinction room.
In order to achieve the above object, the technical scheme that the utility model is used for：
A kind of vacuum extinction cell structure of breaker, it is characterised in that：It is airtight outer including the vertically arranged tubular of central shaft
Shell, air-tight casing upper end nozzle, which is covered, is connected with static side cover plate, and air-tight casing lower end nozzle, which is covered, is connected with moved end cover plate, airtight
Concentrically axle is provided with shielding cylinder, air-tight casing upper and lower end nozzle and is respectively equipped with ceramic seal head in shell, and upper end ceramics are close
End socket bottom, lower end ceramic seal overhead are entered in shielding cylinder corresponding end nozzle by central lug seal plug respectively, static side
Cover plate is provided with static side conducting block, and static side conducting block bottom is connected with static side conducting rod vertically, and static side conducting rod lower end is worn successively
Static side cover plate, upper end ceramic seal head is crossed to stretch into shielding cylinder, and static side conducting rod lower end is connected with static contact, moved end cover plate
Vertically slidable to be equipped with moved end conducting rod, moved end conducting rod lower end passes moved end cover plate and stretched to below the cover plate of moved end, and moved end lid
Plate bottom is provided with the guide sleeve being enclosed on outside the conducting rod of moved end, and it is close that moved end conducting rod upper end sequentially passes through moved end cover plate, lower end ceramics
End socket is stretched into shielding cylinder, and moved end conducting rod upper end is connected with moving contact, and moving contact side wall is provided with ring by annular groove insertion
Correspondence moving contact position slip cap is equipped with annular external magnet on shape internal magnet, the air-tight casing, and annular internal magnet, annular are outer
Magnet 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 on
Ring support support on shell, the bottom fixed cover that the moved end conducting rod passes downwards moved end cover plate is equipped with adapter sleeve, ring
Shape frame bottom is connected by the equally distributed connecting rod of multiple rings with adapter sleeve sidepiece.
In the utility model, annular internal magnet, annular internal magnet and the annular on air-tight casing are embedded in moving contact outer wall
External magnet magnetic is attracting, when moved end conducting rod drives moving contact action, is driven simultaneously by adapter sleeve, connecting rod, ring support
Annular external magnet action, so annular internal magnet drives moved end contact action under magnetive attraction effect, therefore passes through inner and outer annular
Magnet can play a part of auxiliary moving contact action.When moving contact is contacted with static contact, due to equal between inner and outer annular magnet
Even magnetive attraction effect, it is ensured that accurately contacted between dynamic and static contact, if can be entangled under magnetive attraction effect when there is contact deviation
Positive justification moving contact position, realizes the accurate contact of dynamic and static contact, can effectively reduce the contact resistance between dynamic and static contact.
