The harm of the faults such as single-phase earthing, is the important component part of electric power system.
When circuit malfunctions, when chopper monitors the predetermined protective current value that current value exceedes its setting, will
Trigger action mechanism action, makes the rapid disjunction of dynamic and static contact, thus disconnecting circuit.But in breaking course, due to voltage x current
Value is excessive, makes dynamic and static contact produce electric arc in breaking course, electric field is too strong in addition, makes circuit breaker internal gas by highly electricity
From, produce a large amount of free metal ions, the chopper if these free metallics fly out, it is likely to result in the short of perimeter circuit
Road, burn, thus causing disaster.
In the arc-chutes of traditional omnipotent breaker, series of parallel flash barrier can be set, and add above flash barrier
Dress, perpendicular to the single or multiple lift filter screen of flash barrier, eliminates the purpose of free metal ion to realization.This traditional technology
Although scheme can eliminate part free metal particle, but still there is part free metal ion can overflow arc-chutes, there is potential danger
Evil.

Room stops the device that electric arc overflows.Realize in chopper disjunction, by produced electric arc circuit breaker internal pressure drive
Under, reach equipped with the arc extinguishing assembly of metal bar, ionize the ability of ion using the excellent absorption of metal arc surface, so that these is swum
Electric arc residual particles from state are not escaped from arc-chutes, are completely eliminated in arc-chutes, it is achieved thereby that the zero of chopper
Arcing.
Technical scheme
In order to realize above-mentioned technical purpose, one kind zero arcing arc quenching chamber structure of this utility model design, it includes arc extinguishing
Chamber component it is characterised in that：Equipped with arc-chutes cover assembly on described arc extinguishing chamber component, on described arc extinguishing chamber component and arc-chutes
Cap assemblies junction is provided with arc-chutes net-filter assembly；

Zero arcing.
Brief description
Accompanying drawing 1 is the structural representation of this utility model embodiment.
Accompanying drawing 2 is this utility model embodiment exploded view.
Accompanying drawing 3 is arc extinguishing rod mounting structure schematic diagram in this utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples, this utility model is described further.
Embodiment
As shown in figure 1 and 2, a kind of zero arcing arc quenching chamber structure, it includes arc extinguishing chamber component 1, described arc extinguishing chamber component 1
On equipped with arc-chutes cover assembly 2, described arc extinguishing chamber component 1 is provided with arc-chutes filter screen with arc-chutes cover assembly 2 junction
Assembly 3；
Described arc-chutes cover assembly 2 includes covering 201 on arc-chutes, described arc-chutes covers be provided with 201 inner chambers and props up
Frame box 202, described support box 202 is built with the arc extinguishing rod 203 of some parallel installations；
Described arc extinguishing rod 203 is metal circular side, a diameter of 0.5～3mm, in described arc extinguishing rod 203 and arc extinguishing chamber component 1
Arc extinguishing grid pieces 101 parallel.
Described support box 202 is nonmetallic making.
Described arc-chutes net-filter assembly 3 includes drainage screen 301, pad frame 302 and lower drainage screen 303, upper drainage screen 301,

The electric arc producing in disconnection process when chopper dynamic/static contact, makes contact surface melt, forms the gold of free state
Belong to ion, and metal ion produces arc extinguishing gases cloud together with the heating air around electric arc, its volume passes through heating
And expand, after circuit breaker internal chamber pressure raises, arcing gas enters arc-chutes arc extinguishing assembly cooling arc extinguishing, but due to electricity
Arc gas pressure is excessive so that the high-temperature metal ion of part free state passes through grid to reach on arc-chutes with gases at high pressure
Cap assemblies, these high-temperature metal ions first pass through the arc-chutes net-filter assembly making of insulant, and these net-filter assemblies rise
To the effect stopping filtration to the high-temperature metal ion initial stage, subsequent metal ion entrance magnetic conductive metal materials processing
Arc extinguishing rod, because arc extinguishing rod is uniformly distributed in arc extinguishing interior, makes metal ion logical from the arc extinguishing rod passage rearranging
Cross, so that the high-temperature metal ion of these free states can be adsorbed during advancing on the arc extinguishing rod of permeability magnetic material, simultaneously
Because the structure of multilamellar arc extinguishing rod increased the stroke that these metal ions pass through so as to can speed up cooling, finally these trips
From state metal ion completely in arc-chutes absorbed inside so that chopper has reached real zero arcing.
One kind zero arcing arc quenching chamber structure that this utility model provides, by setting up the arc extinguishing rod of multilayer parallel setting, makees
Stop the device that electric arc overflows for arc-chutes.In chopper disjunction, by produced electric arc circuit breaker internal pressure band
Under dynamic, reach equipped with the arc extinguishing assembly of metal bar, ionize the ability of ion using the excellent absorption of metal arc surface, make these
The electric arc residual particles of free state are not escaped from arc-chutes, are completely eliminated in arc-chutes, it is achieved thereby that chopper
Zero arcing.
