As on airport, hospital, the place such as market, once have a power failure, it is necessary to be switched to stand-by power supply rapidly and it is proceeded power supply, it is ensured that work in every proceeds. In this time, for the rapid switching of power supply, double power supply automatic transfer switch just plays a crucial role.
Twin-power switch is mainly made up of a pair moving contact portion and a pair stationary contact head, carrying out closing a floodgate in energising or Power convert process, moving contact portion is close to stationary contact head and contact under the driving of rotating shaft, the moment of moving contact portion and stationary contact head contact, have electric arc to produce, produce powerful electric current simultaneously.
Arc-chutes are mainly placed in centre by current excitation integral type dual-power transfer switch, two moving contact portions are respectively placed in arc-chutes both sides, in carrying out the process of rapid closing or Power convert, electric arc has little time extinguishing can produce string arc phenomenon, it is impossible to carry out combined floodgate or the Power convert of high performance index.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art; there is provided the excitation integral type double power supply automatic transfer switch of the switch Novel belt arc-chutes of a kind of combined floodgate that can carry out high performance index or Power convert, such that it is able to farthest protect moving contact portion and stationary contact head.
The purpose of this utility model is achieved through the following technical solutions: the excitation integral type double power supply automatic transfer switch of Novel belt arc-chutes, including housing, the moving contact portion being placed in housing and stationary contact head, described moving contact portion is two, it is respectively placed in housing left and right symmetric position, described stationary contact head is two, corresponding with position, two moving contact portions respectively, it is characterized in that, side, described left and right moving contact portion is respectively equipped with arc-chutes portion, and two arc-chutes portions are symmetrical and put;Two moving contact portions are respectively arranged below with striking stationary contact head, and two striking stationary contact heads are symmetrical and put, and corresponding with position, two moving contact portions respectively.
The linkage being additionally provided with two symmetries and put, it connects two moving contact portions respectively, and corresponding with position, two moving contact portions.
Described linkage is square shaft linkage.
Described moving contact portion is connected with linkage by contact support.
Described striking stationary contact head is provided with striking grid.
Two moving contact portions are respectively equipped with striking moving contact portion, and two striking moving contact portions are corresponding with two striking stationary contact head positions respectively.
This utility model includes two symmetrically arranged square shaft linkages, respectively the location arrangements in corresponding moving contact portion; Including two symmetrically arranged striking stationary contact heads, the location arrangements in corresponding moving contact portion respectively; Also include two symmetrically arranged arc-chutes portions, respectively the location arrangements in corresponding moving contact portion.
In this utility model, in switch transformation process, moving contact portion is close to stationary contact head and contact under the driving of rotating shaft (square shaft linkage), before turning on, striking moving contact portion contacts in advance with striking stationary contact head, carry out striking, finally by arc-chutes portion arc extinguishing, it is prevented that owing to arc stiffness is excessive and cause the damage to moving contact portion and stationary contact head.
In this utility model, an arc-chutes portion corresponding to stationary contact head of moving contact portion, arranging of two arc-chutes portions can effectively prevent electric arc string phase. This utility model is compared to prior art, it is possible to protection moving contact portion and stationary contact head effectively, it is ensured that arc extinguishing continuous and effective, farthest protection moving contact portion and stationary contact head, improves the service life of dual-power transfer switch.
