Abstract

The invention belongs to low voltage electric equipment, it relates to breaker arc-control device which is used in low voltage breaker. The device includes shell and arc-control bar which is mounted in the cavum of the shell, two layers of elastic reed are set at the exhaust end of the shell, one end of the elastic reed is separately fixed to different side of the shell, the other end of the elastic reed is in free state and adhibited to each other, several bar grooves which are parallel with each other are set in the two layers of elastic reed, the bar grooves are staggered with each other in parallel direction. The invention is simple, action is reliable, and it not only can keep air pressure during the arc-control process, at the same time the pressure can be released automatically when the pressure is too big.

Description

Arc Distinguishing Device for Circuit Breakers
Technical field
The invention belongs to low voltage electrical equipment, relate to a kind of Arc Distinguishing Device for Circuit Breakers 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 exhaust end of arc extinguishing grid pieces, as the passage of air pressure release.Because the gas flux of Perforated decking is fixed, therefore can not play regulating and controlling effect, thereby can not guarantee in the arc extinguishing process, to have comparatively ideal air pressure conditions in the arc control device the air pressure in the arc control device.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Arc Distinguishing Device for Circuit Breakers of simple in structure, reliable in action, makes it can either keep required gas pressure in the arc extinguishing process in arc control device, simultaneously release pressure automatically again when pressure is excessive.
Arc Distinguishing Device for Circuit Breakers of the present invention include housing and be installed in the housing inner chamber arc extinguishing grid pieces, exhaust end at housing is provided with two-layer elastic spring, one end of two-layer elastic spring is separately fixed at the not homonymy of housing sidewall, the other end of two-layer elastic spring is in free state and abuts in mutually together, all having many frame troughs that are parallel to each other on the two-layer elastic spring, staggers mutually in the frame trough position in the horizontal direction on the upper and lower two-layer elastic spring.
The present invention is simple in structure, with low cost, be easy to processing.Because it is provided with the two-layer elastic spring that has frame trough on the exhaust passage of arc control device, when the arc control device internal gas pressure is low, because it is last, the horizontal level of two-layer frame trough staggers mutually down, thereby the flux of gas is less, can make and keep certain air pressure in the arc control device, be beneficial to arc extinguishing, and when the arc control device internal gas pressure surpasses certain value, to make two-layer elastic spring generation strain, the free end of elastic spring outwards lifts, and makes the frame trough on the two-layer elastic spring that relative displacement take place in the horizontal direction, and the overlapping area of two-layer frame trough increases, and then gas flux is increased, too high air pressure can obtain discharging.
Description of drawings
Fig. 1 is the present invention at arc control device air pressure structural representation hour;
Fig. 2 is the local structure for amplifying schematic diagram of the A among Fig. 1;
Fig. 3 is the structural representation of the present invention when arc control device air pressure is big;
Fig. 4 is the local structure for amplifying schematic diagram of the B among Fig. 3.
Embodiment
As shown in the figure, in the housing 1 of Arc Distinguishing Device for Circuit Breakers of the present invention arc extinguishing grid pieces 2 is installed, their common formation arc control device, exhaust end at housing is provided with two-layer elastic spring 3, one end of two-layer elastic spring is separately fixed on the housing two side, the other end of two-layer elastic spring freely abuts in together, staggers mutually in frame trough 4 position in the horizontal direction on the two-layer elastic spring.
When the arc control device internal gas pressure hour, as shown in Figure 1 and Figure 2, two-layer frame trough 4 laps are less or do not have overlappingly, thereby gas flux is less, helps keeping the air pressure in the arc control device; When the arc control device internal gas pressure was higher, as shown in Figure 3, Figure 4, because the free end of elastic spring 3 outwards lifts, relative displacement took place in two-layer frame trough 4, and its lap increases, thereby the corresponding increase of gas flux, can discharge too high air pressure.
