Description
Technical field
This utility model relates to A kind of catalyst, the magnetic of a kind of aviation field keeps high-voltage DC contactor。
Background technology
Along with the development of science and technology, aviation is to the development of multi-functional, multipurpose, and the most its of function uses equipment and components and parts the most, all these both increases the demand to aeronautical power generation.Aviation field uses catalyst to be typically all low-voltage and coil for the working method that is persistently energized at present, therefore when exporting relatively high power load, owing to voltage is low, when exporting relatively high power load, output electric current will become big, can cause that current heating quantitative change is big, energy consumption increases, melting welding adhesion can occur between binding post and contact bridge, reduce the life-span of catalyst；Simultaneously, binding post and contact bridge are when disconnecting, electric arc can be produced between binding post and contact bridge, but traditional contactors is to improve arc quenching effect by increase gap, and for high voltage, the catalyst of big electric current, when contact disconnects, a large amount of electric arc can be produced at contact cleaved facet, only carrying out arc quenching effect by increase gap inconspicuous, therefore, the performance reliability of traditional contactors is relatively low.Simultaneously as coil is the working method that is persistently energized, dress machine system energy consumption also can be made to uprise。
Summary of the invention
The purpose of this utility model is, it is provided that a kind of magnetic keeps high-voltage DC contactor.This utility model have arc quenching effect good,
Load voltage height,
Dependability height, life-span length, product energy consumption are low, anti-vibration, feature that impact capacity is strong.
The technical solution of the utility model: a kind of magnetic keeps high-voltage DC contactor
, including case, the top of case is provided with cover plate, and cover plate is provided with two binding posts, is respectively equipped with a porcelain and blows magnet steel, be provided with movable contact assembly in the case below binding post in the case of binding post both sides.
Aforesaid magnetic keeps high-voltage DC contactor, and described magnetic blow-out magnet steel is arranged on the two ends in binding post bottom center's point line direction.

Aforesaid magnetic keeps high-voltage DC contactor, and between described case with movable contact assembly, ceramics seat and the sealing ring being located at below ceramics seat through being located between binding post with magnetic blow-out magnet steel are connected.
Aforesaid magnetic keeps high-voltage DC contactor, described movable contact assembly includes drive link, the upper end of drive link is provided with contact bridge, the lower end of drive link is provided with iron core, drive link below iron core is provided with armature, iron core and armature be provided around sleeve, sleeve is externally provided with yoke, the bottom of yoke is provided with insulating base, upper and lower between sleeve and yoke is respectively equipped with a set coil and resetting coil, it is equipped with magnetic conductor outside set coil and resetting coil, in being provided with between set coil and resetting coil, puts magnet steel.
Aforesaid magnetic keeps high-voltage DC contactor, described contact bridge is movably arranged on drive link, drive link above contact bridge is provided with back-up ring, drive link below contact bridge is provided with stage clip, upper gasket it is provided with between stage clip and contact bridge, drive link below stage clip is provided with lower back-up ring, lower is provided with lower gasket between back-up ring and stage clip.
The beneficial effects of the utility model: this utility model, by arranging magnetic blow-out magnet steel in binding post both sides, uses magnetic quenching method, substantially increases arc quenching effect, the most also can reach preferable arc quenching effect, improve load voltage of the present utility model；Simultaneously, according to left hand rule, electric arc moves along the direction being perpendicular to magnetic field, electric arc deflects, and makes electric arc burn outside contact, and electric arc cools down rapidly after being elongated, avoid generation high temperature on binding post and contact bridge, thus avoid melting welding adhesion between binding post and contact bridge, improve dependability of the present utility model, extend service life of the present utility model simultaneously.It addition, by inciting somebody to action
Magnetic blow-out magnet steel is arranged on the two ends in binding post bottom center's point line direction, according to left hand rule, two electric arcs formed between binding post and contact bridge can be respectively along two side shiftings of binding post bottom center's point line, will not contact with each other between electric arc, further increase dependability of the present utility model；And by arranging exhaust tube on the contactor, by exhaust tube to having carried out evacuation and inflation (noble gas) PROCESS FOR TREATMENT in arc-chutes, good insulation and resistance to pressure is kept in making catalyst, stable handoff environment is provided for high-voltage contact (binding post and contact bridge), decrease oxidation and corrosivity, simultaneously evacuation and inflation after, contact portion can automatic distinguishing (be the most all the metal high voltage district of evaporation because of electric arc itself when cut-offfing heavy load, after being processed by evacuation and inflation, air or active gases is not had around arcing, guarantee it is good insulation and pressure environment, finally realize the function of arc extinguishing), further increase arc quenching effect of the present utility model and dependability.In addition, this utility model is by putting magnet steel in arranging between set coil and resetting coil, therefore no matter contact bridge is in binding post being connected or off-state, be all lean in put magnet steel and iron core or armature effect, make contact bridge be maintained at fixing position, need to make it change coil electricity without the long-term position that coil electricity keeps contact bridge, the only moment in the conversion of contact bridge position, therefore, the energy consumption needed for coil is greatly reduced；Simultaneously, by being movably arranged on drive link by contact bridge, and fixing a stage clip in the lower section of contact bridge by upper and lower back-up ring and upper lower gasket, stage clip plays the effect of buffering, avoid contact with in bridge transformation process with binding post hard hit, thus further increase service life of the present utility model.
Simultaneously due also to this utility model puts magnet steel (putting magnet steel in i.e. to be between set coil and resetting coil) in using, and armature be in put magnet steel center, and due in put the magnetic field intensity that magnet steel produces relatively big (i.e. magnetic field force is bigger), magnet steel is put in reset state (i.e. contact is off), armature, yoke constitutes magnetic loop, put in and can guarantee that armature is in reset state under magnet steel magnetic field force effect, magnet steel is put in SM set mode (i.e. contact is in an ON state), armature, the ferrum heart, magnetic conductor constitutes magnetic loop, put in and can guarantee that armature is in SM set mode under magnet steel magnetic field force effect, the most either reset state or SM set mode, the magnetic field force putting magnet steel generation in due to is bigger, well armature can be maintained at required state, therefore there is preferable anti-vibrating and impact performance.
In sum, this utility model have arc quenching effect good,
Load voltage height,
Dependability height, life-span length, product energy consumption are low, anti-vibration, beneficial effect that impact capacity is strong.
