Abstract
The utility model relates to a breaker, especially relates to a breaker provided with an arc running channel. The breaker provided with the arc running channel is characterized in that a pedestal and a cover are provided with positioning long protruding diameters, which are symmetrically arranged; the other side of an arc extinguishing chamber, which is far away from the arc running channel, abuts against the positioning long protruding diameters of the pedestal and the cover; arc dividing protruding diameters are symmetrically disposed on lower sides of the positioning long protruding diameters of the pedestal and the cover; the arc dividing protruding diameters can be used to form a curved arc running channel; and side walls of the pedestal and the cover behind the arc dividing diameters are provided with arc spraying ports. By adopting the above mentioned technical scheme, the defects of the prior art can be overcome, and the novel breaker provided in the utility model can be used to solve the problem of the arc restriking phenomenon or the back breakdown phenomenon during the arc extinguishing process of the arc breaking test of the mini-sized breaker.
Description
Technical field
The utility model relates to a kind of circuit breaker, refers to especially with the circuit breaker that runs the arc road.
Background technology
Miniature circuit breaker in the market is the large phenomenon of institute's produce power in disjunction, is that the disjunction arcing time of circuit breaker is long, causes contact system and the striking passage scaling loss of interiors of products, can cause in even serious situation catching fire and the phenomenon such as blast.Yet the race arc duct device of miniature circuit breaker and the design of arc spraying mouth are shortened the arcing time of electric arc, improve the breaking capacity of product.The straight channel formula structure that on market, the race arc road of existing product adopts only has one-sided arc spraying mouth, runs the shortcoming of arc road and arc spraying mouth in this: the quenching time of electric arc in running the arc road be long to be had in causing product arc extinguishing process and restrikes and the back commutation phenomenon.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, provide a kind of miniature circuit breaker electric arc in the disjunction test that can effectively solve that the phenomenon of arc reignition or back commutation occurs in the arc extinguishing process, stop the novel circuit breaker of the ejection of the metal ion that produces in breaking course.
realize above-mentioned purpose, the utility model adopts following technical scheme, a kind of circuit breaker with running the arc road, include base, lid, handle, trigger device, fixed contact, calutron and arc control device, wherein base and covering is provided with the striking road, calutron and arc control device all are fixedly installed on base and cover, it is characterized in that: described base or/and cover is provided with long protruding footpath, location, arc control device are conflicted on long protruding footpath, location away from the lateral surface of the opposite side in striking road, described base is or/and cover and the downside that is positioned at long protruding footpath, location is provided with electric arc and cuts apart protruding footpath, electric arc is cut apart protruding footpath and is consisted of crooked race arc road, described base is provided with arc spraying mouth or/and lid is positioned on side wall surface after electric arc is cut apart protruding footpath.
Further setting of the present utility model is: described base is grown protruding footpath with the location that is provided with that covers symmetry, described base and cover and the downside that is positioned at long protruding footpath, location is symmetrically arranged with electric arc and cuts apart protruding footpath, base coordinates with the end face conflict that the electric arc that covers correspondence is cut apart protruding footpath, and described base is provided with arc spraying mouth with covering on the side wall surface that is positioned at after electric arc is cut apart protruding footpath.
Of the present utility model further the setting again is: be provided with three sections electric arcs on described base and cut apart protruding footpath, also be provided with three sections electric arcs on corresponding lid and cut apart protruding footpath, what three sections electric arc was cut apart protruding footpath is wired to the triangle setting, described arc spraying mouth is provided with two at least, one of them is positioned on the downside wall of base and lid, and another arranges on the side wall adjacent with the downside wall of base and lid.
By adopting above-mentioned scheme, the effect that the utility model reaches is:
1, long protruding footpath, location fixes arc control device, prevents that in breaking course electric arc enters arc control device moments and produces a kind of suction and cause arc control device to tilt, and causes the arc extinction performance of product to descend;
2, electric arc enters arc control device electric arc is divided into the tiny short arc of many strips, reduce arc voltage, but also have part electric arc out to enter electric arc from the arc control device rear wall and cut apart the race arc road that protruding footpath consists of bending, to reduce flashover distance, also have residual electric arc and free gas to discharge from two-way arc spraying mouth respectively, two-way arc spraying mouth can allow free gas cooling fast, plays cooling effect, realizes better arc extinguishing.
Below in conjunction with accompanying drawing, the utility model is further described.
