Abstract
An electric leakage breaker arc extinguishing device with a static contact connecting pillar is provided; the device comprises a connecting sheet (1), the static contact (2), an arc extinguishing grid (4), an arc extinguishing grid support (5) and a moving contact (6); the vertical connecting pillar (3) is erected between the connecting sheet (1) and the static contact (2). The electric leakage breaker arc extinguishing device with the static contact connecting pillar is specially used for structural improvement of the electric leakage breaker arc extinguishing device static contact, thereby improving magnetic field intensity of short circuit current in an explosion chamber, accelerating motion speed of the arc, and nearly doubling the arc extinguishing capability.
Description
Technical field
The utility model relates to the arc-control device of a kind of electronic component ，Shi arc eliminating chamber, is specially the modified model arc-control device of residual current circuit breaker.
Background technology
Fixed contact in residual current circuit breaker arc-control device is continued to use the outer end of static contact and the mode of lug plate level overlap joint always, and the magnetic field force that electric current produces while flowing through static contact had not obtained also cannot effectively being applied, and was difficult to improve arc-control device breaking capacity.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of residual current circuit breaker arc-control device with fixed contact joint pin.
Solve present technique problem and adopt following technical scheme: this,, with the residual current circuit breaker arc-control device of fixed contact joint pin, comprises brace, fixed contact, and arc-chute, go out lonely grid support and moving contact, set up joint pin longitudinally between brace and fixed contact.
The beneficial effects of the utility model are: on fixed contact, added joint pin longitudinally, electric current from brace through joint pin to static contact, after electric current is connected, joint pin just has the downward electric current of flowing through, the consistent result of magnetic line of force direction of arcing current in the time of just can producing magnetic direction with disjunction, improve nearly one times of magnetic field force, arc extinguishing ability is doubled.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the annexation figure of the utility model in residual current circuit breaker movement.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing: with reference to Fig. 1, this is with the residual current circuit breaker arc-control device of fixed contact joint pin, comprise brace 1, fixed contact 2, arc-chute 4, arc-chute support 5 and moving contact 6, between brace 1 and fixed contact 2, set up joint pin 3. longitudinally
As everyone knows, the arc quenching principle of air circuit arc-control device is: arc quenching system is comprised of lug plate 1, fixed contact 2, arc control device and moving contact 6, when circuit breaker carries out short circuit breaking, short circuit current can produce arc-chute 4, moving contact 6 these sequential flow mistakes of arcing current during along brace 1, fixed contact 2, disjunction, because energized conductor around can produce magnetic field, and and the proportional relation of electric current of flowing through; Therefore, short circuit current can produce certain magnetic field in arc-chute 4; Short circuit arcing current can move under the effect of magnetic field force in arc control device, the magnetic blow-out effect in breaker arc extinguishing technology that Here it is; Short circuiting arc, under the effects such as magnetic field, gas field, is intercepted by arc-chute 4, is divided into a plurality of segmental arcs, thereby makes electric arc lower the temperature rapidly and extinguish.
According to above-mentioned arc quenching principle, we are between brace 1 and fixed contact 2, increase a joint pin 3 longitudinally, the benefit of setting up this joint pin 3 is, the sense of current that is flow to joint pin 3 by brace 1 is downward, the direction that arcing current makes progress when flowing through disjunction antithesis, the magnetic line of force direction that makes joint pin 3 during with disjunction the magnetic line of force direction of arcing current consistent, strengthened the magnetic field intensity that short circuit current forms in arc control device, strengthen the magnetic field force of the short circuiting arc of nearly a times, accelerate the movement velocity of electric arc, thereby improved the arc extinguishing ability of this device.
Claims (1)
1. the residual current circuit breaker arc-control device with fixed contact joint pin, comprise brace (1), fixed contact (2), arc-chute (4), go out lonely grid support (5) and moving contact (6), it is characterized in that having set up between brace (1) and fixed contact (2) joint pin (3) longitudinally.
