Specific embodiment
With reference to the accompanying drawings and examples, this utility model is elaborated.
Embodiment
As shown in accompanying drawing 1～4, a kind of to strengthen the zero arcing arc quenching chamber structure for eliminating electric arc ability, it includes arc-chutes group
Part 1, is equipped with arc-chutes cover assembly 2 on the arc extinguishing chamber component 1, the arc extinguishing chamber component 1 is connected with arc-chutes cover assembly 2
Place is provided with arc-chutes net-filter assembly 3；
The arc-chutes cover assembly 2 includes lid 201 on arc-chutes, is distinguished with rear side on arc-chutes on front side of 201 inner chamber of lid
Be provided with fore-stock 201a and after-poppet 201b, upper left baffle plate 202 and lower-left baffle plate 203 two ends be attached separately to fore-stock 201a and
On after-poppet 201b, the two ends of bottom right baffle plate 204 are mounted on fore-stock 201a and after-poppet 201b, fore-stock 201a and after-poppet
It is located on 201b between lower-left baffle plate 203 and bottom right baffle plate 204 and some arc quenching plates 205 is housed；
The arc quenching plate 205 is w shapes, and w shapes arc quenching plate 205 is laterally stacked side by side, and its two ends is mounted in fore-stock 201a
On after-poppet 201b.
The arc quenching plate 205 is sheet metal.
The fore-stock 201a and after-poppet 201b is nonmetallic making.
The arc-chutes net-filter assembly 3 includes drainage screen 301, pad frame 302 and lower drainage screen 303, upper drainage screen 301,

When the electric arc that chopper dynamic/static contact is produced in disconnection process, melt contact surface, form the gold of free state
Category ion, and metal ion produces arc extinguishing gases cloud together with the heating air around electric arc, its volume is by heating
And expand, after circuit breaker internal chamber pressure is raised, arcing gas enters arc-chutes arc extinguishing component and cools down arc extinguishing, but due to electricity
Arc gas pressure is excessive so that the high-temperature metal ion of part free state is reached on arc-chutes through grid with gases at high pressure
Cap assemblies, these high-temperature metal ions first pass through the arc-chutes net-filter assembly made of insulant, and these net-filter assemblies rise
To the effect that the stop to the high-temperature metal ion initial stage is filtered, subsequent metal ion is into being suppressed with magnetic conductive metal material
W type arc quenching plates, as W type arc quenching plate two ends are sealed with magnetic conductive metal baffle plate, make the metal ion can only be from the W for rearranging
Pass through in type arc quenching plate passage, the high-temperature metal ion of these free states is adsorbed in permeability magnetic material during traveling
W type arc quenching plates on, simultaneously because the structure of W type arc quenching plates increased the stroke that these metal ions pass through so as to Neng Goujia
Quickly cooling but, the metal ion of final these free states completely in arc-chutes absorbed inside so that chopper has reached really
Zero arcing.
A kind of enhancing that this utility model is provided eliminates zero arcing arc quenching chamber structure of electric arc ability, by putting down in traditional
Increase the free gass device that disappears for being furnished with W type arc quenching plates above row groups of arc plates.Effectively can eliminate in high current disjunction due to
The free metal particle of the highly ionized state that disjunction is produced, prevent free ionizing particle from flying out arc-chutes, it is to avoid alternate
The harm of short circuit, realizes zero arcing of high current disjunction.
