Abstract

An improved breaker comprises a pedestal, an arc extinguishing device, a moving contact, a baffle plate and a static contact. The arc extinguishing device is arranged on the pedestal. The moving contact is arranged on the front side of the arc extinguishing device. The baffle plate is arranged on the back side of the arc extinguishing device. The static contact is arranged under the moving contact. The moving contact, the baffle plate and the static contact are respectively disposed on the pedestal. The moving contact is mated with the static contact. The outer surface of the baffle plate is provided with grooves, and flanges are formed between the adjacent grooves. The grooves and the flanges together form a heat radiation structure. During an arc extinguishing process, the temperature of the whole breaker can be effectively reduced and does not rise rapidly. The improved breaker has the advantages of fast arc extinguishing speed and short arc extinguishing time. In addition, the service life of the breaker is prolonged and the electrical performance of the breaker is guaranteed.

Description

A kind of improved circuit breaker
Technical field
The utility model relates to a kind of improved circuit breaker.
Background technology
The dynamic and static contact of circuit breaker is when the disjunction short circuit current; Tend to produce high-temperature electric arc, this high-temperature electric arc is bigger to the harm of circuit breaker, if can not apace it be concentrated; And introduce arc extinguishing in the arc control device apace; High-temperature electric arc will be burnt contact system, and the lighter can seriously reduce the interrupting performance of circuit breaker, and weight person will burn electrical equipment.Yet existing arc quenching effect is not ideal, and reason is the open slot place that high-temperature electric arc gets into the arc quenching plate group, and the temperature of whole circuit breaker is raise fast, causes arc extinguishing slower, the problem that the quenching time is relatively long.
Summary of the invention
It is fast that the technical problem that the utility model will solve provides a kind of arc extinguishing speed, the improved circuit breaker that the quenching time is short.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: comprise base, and be arranged on the arc-control device on the base, and be installed in the moving contact of arc-control device front side; And be installed in the baffle plate of arc-control device rear side, and be installed in the fixed contact of moving contact below; Said moving contact, baffle plate and fixed contact are installed on the base respectively, and moving contact matches with fixed contact; Said baffle plate outer surface has groove, forms flange between adjacent trenches, and said groove and flange form radiator structure jointly.
Further, said arc-control device comprises more than one arc quenching plate and two supports, and support also is mounted on the base.
Further, every arc quenching plate is equipped with a U type open slot, and each arc quenching plate is up and down at interval and is installed between two supports shape, and the openend of the U type open slot of every arc quenching plate is all towards moving contact, moving contact is contained in the U type open slot.
Further, the size of every arc quenching plate and shape are just the same.
The improved circuit breaker of the utility model, owing to be provided with radiator structure, in the process of arc extinguishing; Can effectively reduce the temperature of whole circuit breaker; Temperature is raise fast, and it is fast that it has arc extinguishing speed, the advantage that the quenching time is short; The useful life that simultaneously can improve circuit breaker, the electric property of assurance circuit breaker.
Description of drawings
Fig. 1 is the sketch map of the improved circuit breaker of the utility model.
Embodiment
In the present embodiment, with reference to Fig. 1, said improved circuit breaker; Comprise base 1, and be arranged on the arc-control device 2 on the base 1, and be installed in the moving contact 3 of arc-control device 2 front sides; And be installed in the baffle plate 4 of arc-control device 2 rear sides, and be installed in the fixed contact 5 of moving contact 3 belows; Said moving contact 3, baffle plate 4 and fixed contact 5 are installed in respectively on the base 1, and moving contact 3 matches with fixed contact 5; Said baffle plate 4 outer surfaces have groove 40, and 40 of adjacent trenches form flange 41, said groove 40 and the flange 41 common radiator structures that form.In the process of arc extinguishing, can effectively reduce the temperature of whole circuit breaker, temperature is raise fast, it is fast that it has arc extinguishing speed, the advantage that the quenching time is short, the useful life that can improve circuit breaker simultaneously, the electric property of assurance circuit breaker.
Wherein, said arc-control device 2 comprises more than one arc quenching plate 20 and two supports 21, and support 21 also is mounted on the base 1.Every arc quenching plate 20 is equipped with a U type open slot 22, and each arc quenching plate 20 is up and down at interval and is installed between two supports 21 shape, and the openend of the U type open slot 22 of every arc quenching plate 20 is all towards moving contact 3, so that moving contact 3 is contained in the U type open slot 22.The size and the shape of every arc quenching plate 20 are just the same.
The improved circuit breaker of the utility model, owing to be provided with radiator structure, in the process of arc extinguishing; Can effectively reduce the temperature of whole circuit breaker; Temperature is raise fast, and it is fast that it has arc extinguishing speed, the advantage that the quenching time is short; The useful life that simultaneously can improve circuit breaker, the electric property of assurance circuit breaker.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
