Abstract
The utility model discloses an arc-extinguisher structure of circuit breaker with leakage protector, which comprises a plurality of grid plates and a plurality of side plates fixedly arranged on both sides of the grid plates; wherein, the grid plates are vertically arranged with intervals; the shape of arc-extinguisher is trapezoid; the length of the upper layer grid plate is smaller than the length of the lower layer grid plate. The utility model has the advantages of being suitable for the circuit breaker with a trapezoid arc-quenching chamber, fully utilizing the space of arc-quenching chamber, facilitating the elimination of heat, and good performance of cold-arc and arc-quenching.
Description
Technical field
The utility model relates to a kind of arc-extinguish chamber of circuit breaker, is meant a kind of arc-extinguish chamber of the circuit breaker with earth leakage protective device specifically.
Background technology
The arc-extinguish chamber of the circuit breaker of existing band earth leakage protective device generally is square; because the arc control device of circuit breaker generally are trapezoidal or square; and the arc quenching effect of arc-extinguish chamber is directly proportional with the volume of arc-extinguish chamber; when square arc-extinguish chamber is installed on trapezoidal arc control device; can't make full use of the arc control device space, reach best arc quenching effect; and square arc-extinguish chamber is because the length of each layer Turbogrid plates is the same, and it is slower to dispel the heat, and is unfavorable for quick cold arc and arc extinguishing.
The utility model content
The utility model provides a kind of arc-extinguish chamber, can reach preferable cold arc and arc quenching effect.
The utility model adopts following technical scheme:
A kind of arc-extinguish chamber of the circuit breaker with earth leakage protective device; be made up of some Turbogrid plates and the side plate that is fixedly arranged on the Turbogrid plates both sides, described Turbogrid plates longitudinally are provided with at interval, wherein; described arc-extinguish chamber profile is trapezoidal shape, and the length of the Turbogrid plates on upper strata is less than the length of the Turbogrid plates of lower floor.
A kind of preferable rectangular trapezoidal shape of arc-extinguish chamber profile, and its longitudinal side caves inward and forms vertical " V " shape groove.
By above-mentioned description to the utility model structure as can be known, compare with prior art, profile of the present utility model is trapezoidal shape, can make full use of the arc control device that are trapezoidal; And the length of the Turbogrid plates on upper strata is convenient to the heat radiation of the Turbogrid plates of lower floor less than the length of the Turbogrid plates of lower floor, thereby reaches preferable cold arc and arc quenching effect.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Fig. 3 is the utility model stereogram.
Fig. 4 is installed on schematic diagram in the circuit breaker for the utility model.
Embodiment
Describe embodiment of the present utility model in detail below with reference to Fig. 1-4.
The roughly rectangular trapezoidal shape of this arc-extinguish chamber 1 structure; be applied in the circuit breaker with earth leakage protective device; Turbogrid plates 3 both sides are provided with the installation slotted eye, and side plate 2 is inserted in Turbogrid plates 3 longitudinally are provided with at interval, and the length of its Turbogrid plates at the middle and upper levels is less than the length of the Turbogrid plates of lower floor.The right longitudinal side of arc-extinguish chamber 1 is to being provided with " V " shape groove 4.The utility model is applicable to that arc control device are in the trapezoidal circuit breaker, can make full use of the space of arc control device, is convenient to heat radiation simultaneously, reaches preferable cold arc and arc quenching effect.
Above-mentioned is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection range.
