Description
Technical field
The invention belongs to breaker technical fields, are exactly specifically to be related to a kind of arc-control device with semiclosed chamber.
Background technology
Breaker is the pith in electrical power distribution apparatus, is mainly used for industrial low-voltage power system, for connecting and dividing
The danger of electric current and protection circuit and power-supply device in disconnected mains-power circuit from failures such as overload, under-voltage, short circuit, single-phase earthings
Evil.The function that breaker carries out overload or short circuit current disjunction is mainly to be completed by the arc-chutes in breaker
's.When the electric current that breaks down in circuit, and when current value is more than the setting protection domain of breaker, tripping mechanism action makes
The dynamic and static contact of breaker disconnects rapidly, and the voltage between dynamic and static contact causes air dielectric electric discharge to generate high temperature at this time
Electric arc.Electric arc causes the air themperature in arc-control device to steeply rise to accelerate air ionization in combustion.Another party
Face under the promotion in magnetic field and hydrodynamic effect of the electric arc in arc-chutes, is separated into multiple short arcs, by gold by multiple arc grid
Belong to the deionization effect that arc piece strengthens electric arc, electric arc becomes smaller and voltage rapidly increases, and makes arc extinction.
With the development of the new energy industry such as photovoltaic, breaker rated operational voltage is required higher and higher.Arc voltage
It is higher, it is more advantageous for arc extinguishing.Existing arc extinguishing process is that sound contact both sides are formed narrow channel by gas exhausted material, when dynamic
Gas exhausted material causes air pressure in channel to increase to form air-blowing under high arc temperature effect when static contact disconnects, and keeps electric arc quick
It is moved to arc extinguishing grid pieces direction to achieve the purpose that arc extinguishing.But gas exhausted material forms one two during this traditional arc extinguishing
Hold open channels, the gas in channel that can quickly be discharged, hyperbar can not continue to maintain, and cause arc voltage that can comparatively fast fall.
Chinese patent ZL201510770423.6 discloses a kind of moulded case circuit breaker with semiclosed arc-chutes.Its
Feature is to use semi-enclosed arc-chutes technology, i.e., according to the shape and the two of static contact component and arc-chute in assembly
Position relationship, the arc-extinguish chamber of two mutual mirror images docking is devised, for by static contact component, arc-chute and Du Pont's cardboard
It is connected in inside the two arc-extinguish chambers, and then is integrated into an integral module, which strengthens the air-tightness of arc-chutes.
But it does not have the gas exhausted material of insulation to separate between contact and grid, air-blowing effect is poor.
Invention content
The purpose of the present invention is ineffective aiming at the air-blowing of the above-mentioned existing arc-control device with semiclosed chamber
Technological deficiency, provide a kind of arc-control device with semiclosed chamber, gas exhausted material area bigger, the gas of generation is in aerogenesis
In the semiclosed chamber that material is formed, so that chamber interior energy is kept the hyperbar of a period of time, make the gas in channel at one section
Between interior energy be discharged continuously and healthily, to maintain high arc voltage, to achieve the purpose that fast arc extinction.
Technical solution
In order to achieve the above technical purposes, a kind of arc-control device with semiclosed chamber that the present invention designs, it includes
Arc extinguishing grid pieces group, the arc extinguishing grid pieces group, which is located on the side of moving contact and static contact coupling, is equipped with semi-enclosed insulation aerogenesis
The lateral surface of cover, the insulation aerogenesis cover is equipped with the feeder connection stretched into for moving contact and static contact, and medial surface overflows equipped with gas
Outlet, it is characterised in that：The openings of sizes of the feeder connection and gas overfall is shunk from inside to outside.
Further, the gas overflowing mouth is more than the feeder connection.
Further, the insulation aerogenesis cover is made of gas exhausted material.
Advantageous effect
A kind of arc-control device with semiclosed chamber provided by the invention, gas exhausted material area bigger, the gas of generation
In the semiclosed chamber that gas exhausted material is formed, so that chamber interior energy is kept the hyperbar of a period of time, the gas in channel is made to exist
A period of time interior energy is discharged continuously and healthily, to maintain high arc voltage, to achieve the purpose that fast arc extinction.
