Abstract

The invention belongs to low voltage electric equipment, it relates to breaker gas pressure arc-control device which is used in low voltage breaker. The device includes shell and arc blow-out gate which is mounted in the cavity of shell, metallic cover plate with vent hole is set on top of the shell; twp layers of porous metal plates which are inarching with each other are set between the metallic cover plate and arc blow-out gate, elastic cell which can make porous metal plates move horizontally is set between the edge of two layers of porous metal plates and side wall of the shell; the shape of elevation profile of porous metal plates is right-angle trapezium, that is via hole possesses a vertical side wall and a inclined side wall, the inclined side wall of via hole of upper layer porous metal plate and the inclined side wall of lower layer porous metal plate are in different side, and the position of via hole of upper and lower layer of porous metal plates is cross with each other. The invention is simple, and action is reliable, it can regulate and control the air pressure of arc-chute automatically.

Description

Pneumatic breaker interrupter device
Technical field
The invention belongs to low voltage electrical equipment, relate to a kind of Pneumatic breaker interrupter device that in low-voltage circuit breaker, uses.
Background technology
The arc-control device of low-voltage circuit breaker generally comprises arc control device that are made of insulation shell, in arc control device, be provided with the multilayer arc extinguishing grid pieces, when arc-control device occurs at circuit breaker electric arc, can in arc control device, produce bigger air pressure, certain air pressure helps arc extinguishing, but air pressure needs again pressure is discharged when excessive.Common arc-control device generally is the cover plate that porous is set at the top of arc extinguishing grid pieces, as the passage of air pressure release.Because the air-flow flux of Perforated decking is fixed, therefore can not play the effect that the arc control device internal gas pressure is regulated and control, thereby can not guarantee in the arc extinguishing process, to have comparatively ideal air pressure conditions in the arc control device.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, reliable in action, can carry out the Pneumatic breaker interrupter device of auto-control to the arc control device internal gas pressure.
Pneumatic breaker interrupter device of the present invention include housing and be installed in the housing inner chamber arc extinguishing grid pieces, be provided with the metal cover board that has air vent hole in case top; Between the top of metal cover board and arc extinguishing grid pieces, be provided with the two-layer expanded metal that abuts in mutually together, be provided with the flexible member that expanded metal is moved horizontally between the sidewall of two-layer porous metals panel edges and housing; The vertical section of through hole is shaped as right-angled trapezium on the expanded metal, be that through hole has a vertical sidewall and a sloped sidewall, the sloped sidewall of the sloped sidewall of through hole and lower floor's expanded metal is positioned at not homonymy on the expanded metal of upper strata, and the lead to the hole site on the upper and lower two-layer expanded metal staggers mutually.Described flexible member can be that level is installed in the compression spring between expanded metal side and the housing sidewall.
The present invention is owing to be provided with through hole with right-angled trapezium vertical section and expanded metal that lead to the hole site staggers mutually on the exhaust passage of arc control device, thereby when the arc control device internal gas pressure hour, air-flow can pass through from the less gap between the two-layer through hole up and down, its exhaust flux is less, can satisfy the required gas pressure of arc extinguishing.And when the arc control device internal gas pressure surpasses certain value, the horizontal component of air pressure on the sloped sidewall of through hole makes expanded metal overcome the elastic force of flexible member and moves horizontally, because the sloped sidewall of upper and lower two-layer through hole is positioned at not homonymy, thereby the direction that two-layer expanded metal moves is opposite, gap between the upper and lower two-layer through hole is increased, the also corresponding increase of exhaust flux, thus excessive pressure discharged.This structure reliable in action, simple in structure, with low cost, be easy to realize.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the local enlarged diagram of the A of Fig. 1.
Embodiment
As shown in Figure 1, in the housing 1 of Pneumatic breaker interrupter device of the present invention arc extinguishing grid pieces 2 is installed, their common formation arc control device, be provided with the metal cover board 3 that has steam vent in case top, two-layer expanded metal 4 is arranged between metal cover board 3 and arc extinguishing grid pieces 2, and two-layer expanded metal side is connected with housing sidewall by the compression spring as flexible member 5 respectively.
As shown in Figure 2, on the two-layer expanded metal stagger mutually in the position of through hole 41, and through hole 41 has a vertical sidewall 411 and a sloped sidewall 412, and its vertical section is shaped as right-angled trapezium, and the sloped sidewall 412 of upper and lower two-layer through hole is positioned at not homonymy.Like this, when gas pressure was on sloped sidewall 412, it was opposite to the horizontal component direction that two-layer expanded metal produces, when horizontal component overcomes the elastic force of compression spring, two-layer expanded metal is moved horizontally round about, thereby increase air-flow flux, release pressure.
