Description
Technical field
The invention belongs to breaker technical field, is exactly specifically to be related to a kind of breaker arc extinguishing space-closed knot
Structure, electric arc can be promoted to enter arc-chutes faster, shorten the arc extinction time.
Background technology
Breaker is the pith in electrical power distribution apparatus, is mainly used in industrial low-voltage power system, for connecing
The logical and electric current in disjunction mains-power circuit and protection circuit and power-supply device from overload, under-voltage, short circuit,
The harm of the failures such as single-phase earthing.
Breaker carries out the function of disjunction to overload or short circuit current mainly by breaker
What arc-chutes were completed.When the electric current that broken down in circuit, and current value exceedes the setting guarantor of intelligent controller
When protecting scope, driving operating mechanism action, the dynamic and static contact of breaker is disconnected rapidly, now it is dynamic,
Voltage between static contact causes air dielectric to discharge and produce high-temperature electric arc.Electric arc causes to go out in combustion
Air themperature in arc device is steeply risen so as to accelerate air ionization.On the other hand, electric arc is in arc-chutes
Magnetic field and hydrodynamic effect promotion under, multiple short arcs are separated into by multiple arc grid, by metal arc
Piece strengthens the deionization effect of electric arc, and electric arc diminishes and voltage rapidly raises, and makes arc extinction.
Existing miniature circuit breaker arc-chutes communicate in other spaces with enclosure interior, during disjunction short circuit current, aerogenesis
Material can reduce with partial pressure caused by electric arc heating because scattered to whole housing direction, be unfavorable for promoting
Electric arc is completely into arc-chutes so that the arc extinction time is relatively long.
The content of the invention
The purpose of the present invention is aiming at above-mentioned existing miniature circuit breaker arc-chutes and other spaces of enclosure interior
Communicate and lead to not promote technological deficiency of the electric arc completely into arc-chutes, there is provided a kind of breaker arc extinguishing space
Enclosed construction, using the improvement of existing housing and moving contact installation structure, make dynamic/static contact, arc-chutes until
Gas outlet and other zone isolations of housing, form completely enclosed arc extinguishing space, and pressure is bigger in closing space,
The promotion electric arc that the back pressure of formation is favourable enters arc-chutes faster, shortens the arc extinction time.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of breaker arc extinguishing space-closed structure that the present invention designs, it
Including housing, moving contact and static contact panel, it is characterised in that：The housing is provided with closing gusset, moving contact
In moving contact seal, the closing gusset, inner walls, static contact panel and moving contact seal are formed
One confined space surrounds arc-chutes wherein.
Further, described closing gusset one end connects with static contact panel, and the other end is connected in housing left side wall.
Further, the moving contact seal includes upper seal and lower seal, and moving contact is mounted in upper sealing
In the sealing cavity that part and lower seal are formed, the head of moving contact passes sealing cavity and put in arc-chutes,
Afterbody stretches out moving contact seal, and the lower seal stretches out jut, the moving contact seal both sides with
Static contact panel connects.
Beneficial effect
A kind of breaker arc extinguishing space-closed structure provided by the invention, installed using existing housing and moving contact
The improvement of structure, make dynamic/static contact, arc-chutes until gas outlet and housing other zone isolations, are formed completely
The arc extinguishing space of closing, pressure is bigger in closing space, and the promotion electric arc that the back pressure of formation is favourable enters faster
Enter arc-chutes, shorten the arc extinction time, lift arc extinguishing quality, while the disjunction energy of breaker can also be improved
Power.
