The utility model discloses a to the improvement of the run -on plate structure of explosion chamber, when the moving contact was opened to the biggest opening range, V -arrangement striking structure caused its self structure with electric arc from the moving contact rapidly to reach the purpose that improves circuit breaker breaking capacity, improved the striking ability of explosion chamber, reduced the overflow drain of electric arc, guaranteed the security of circuit breaker sound contact use.
Description
Technical field
This utility model belongs to breaker technical field, the most just relates to a kind of arc-extinguishing chamber of circuit breaker improvement
Structure.
Background technology
Chopper is the pith in electrical power distribution apparatus, will be used for industrial low-voltage power system, be used for connect and
Electric current in disjunction mains-power circuit and protection circuit and power-supply device are from overload, under-voltage, short circuit, single-phase
The harm of the faults such as ground connection.Chopper carries out the function of disjunction mainly by installing to overload or short circuit current
Arc-chutes in chopper complete.When the electric current that breaks down in circuit, and current value exceedes intelligence control
During the setting protection domain of device processed, drive operating mechanism action, make the dynamic and static contact of chopper disconnect rapidly,
Now the voltage between dynamic and static contact causes air dielectric electric discharge thus produces high-temperature electric arc.Electric arc is in burning
During cause the air themperature in arc-control device to steeply rise thus accelerate air ionization.On the other hand, electricity
Under the promotion of arc magnetic field in arc-chutes and hydrodynamic effect, it is separated into multiple short arc by multiple arc grid,
Relying on the deionization effect of metal arc sheet strengthening electric arc, electric arc diminishes and voltage raises rapidly, makes electric arc
Extinguish.
Dynamic/static contact is disconnected the high-temperature electric arc that electric discharge produces by run-on tab by the arc-chutes of existing chopper
Introducing arc-chutes to extinguish, the most traditional run-on tab architecture simply causes run-on tab to draw electric arc
Arc poor effect, easily produces the generation of electric arc spill and leakage phenomenon, can burn out chopper dynamic/static contact time serious.
Utility model content
The purpose of this utility model is aiming at existing arc-chutes striking poor effect, is susceptible to electric arc and overflows
The technological deficiency of leakage, it is provided that a kind of arc-extinguishing chamber of circuit breaker structure-improved, by the run-on tab structure to arc-chutes
Improvement, improve the striking ability of arc-chutes, decrease the spill and leakage of electric arc, it is ensured that chopper sound touch
The safety that head uses.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of arc-extinguishing chamber of circuit breaker structure-improved of this utility model design,
It includes that left flash barrier and right flash barrier, striking grid and some arc extinguishing grid pieces both sides are attached separately to left flash barrier
With right flash barrier, described striking grid is positioned at above arc extinguishing grid pieces, it is characterised in that: described striking grid bag
Including arc extinguishing portion, V-arrangement bending striking portion is stretched out front end in arc extinguishing portion.
Further, described arc extinguishing grid pieces is that flat plate jaggy is opened in front end, and projection, protruding dress are stretched out in its both sides
In the installing hole that left flash barrier is corresponding with right flash barrier.
Further, described arc extinguishing portion is that flat plate jaggy is opened in front end, and striking portion is arranged on indentation, there.
Beneficial effect
A kind of arc-extinguishing chamber of circuit breaker structure-improved that this utility model provides, by hardening to the striking of arc-chutes
The improvement of structure, when moving contact is opened to large opening, electric arc is caused rapidly by V-arrangement arc-striking structure from moving contact
Himself structure, thus reach to improve the purpose of chopper breaking capacity, improve the striking ability of arc-chutes,
Decrease the spill and leakage of electric arc, it is ensured that the safety that chopper dynamic/static contact uses.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model embodiment.
Accompanying drawing 2 is the structural representation of striking grid in this utility model embodiment.
Accompanying drawing 3 is the structural representation of arc extinguishing grid pieces in this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is described further.
Embodiment
As shown in accompanying drawing 1,2 and 3, a kind of arc-extinguishing chamber of circuit breaker structure-improved, it includes left flash barrier 1 He
Right flash barrier 2, striking grid 3 and some arc extinguishing grid pieces 4 both sides are attached separately to left flash barrier 1 and right flash barrier
2, described striking grid 3 is positioned at above arc extinguishing grid pieces 4, it is characterised in that: described striking grid 3 includes going out
Arc portion 301, V-arrangement bending striking portion 302 is stretched out front end in arc extinguishing portion 301.
Described arc extinguishing grid pieces 4 opens flat plate jaggy for front end, and its both sides stretch out protruding 401, protruding 401
It is contained in the installing hole of left flash barrier 1 and right flash barrier 2 correspondence.
Described arc extinguishing portion 301 opens flat plate jaggy for front end, and striking portion 302 is arranged on indentation, there.
When electric arc is by promoting it under the electromagnetic force moved in arc-chutes direction, and this v-shaped structure touches dynamic
The striking of head is advantageously.Thus realize quickly from moving contact, electric arc is caused arc-striking structure, and then reduce electricity
Arc enters arc-chutes strengthen its arc quenching effect to ablation and the quickening electric arc of moving contact, is finally reached raising open circuit
The effect of device breaking capacity.
A kind of arc-extinguishing chamber of circuit breaker structure-improved that this utility model provides, by hardening to the striking of arc-chutes
The improvement of structure, when moving contact is opened to large opening, electric arc is caused rapidly by V-arrangement arc-striking structure from moving contact
Himself structure, thus reach to improve the purpose of chopper breaking capacity, improve the striking ability of arc-chutes,
Decrease the spill and leakage of electric arc, it is ensured that the safety that chopper dynamic/static contact uses.
