Abstract
The invention discloses a double-moving-contact switch device which comprises a shell, an arc extinguish chamber, a contact system and brake devices. The contact system comprises a first moving contact and a second moving contact. A base is arranged in the arc extinguish chamber and provided with a fuse wire. The first moving contact and the second moving contact make contact or are away from the fuse wire from the two sides respectively, and at least two sets of insulated gate pieces are arranged above the fuse wire, the first moving contact and the second moving contact in the arc extinguish chamber. The brake devices are arranged at one end of the outer side of the first moving contact and one end of the outer side of the second moving contact respectively. The double-moving-contact switch device is reasonable in structure and easy to use; the double moving contacts and the insulated gate pieces are used, and an arc can be effectively distinguished; in addition, the arranged fuse wire can better protect a circuit, and the double-moving-contact switch device is much practical.
Description
Technical field
The present invention relates to a kind of electric power switch apparatus.
Background technology
Electric power switch apparatus is the control assembly of power industry outbalance, is one and can makes open circuit, makes current interruptions or make its electronic component that flows to other circuit, generally comprises contact system, arc-control device and wrench device.Switch, when opening or cutting out, can make air ionization, produces electric arc, and to switch and around cause damage, so the validity of switch arc-control device is the critical component addressing this problem.In prior art, utilize single movable contact system, in conjunction with comparatively complicated arc-control device, not only cost is higher more, and effect is also not satisfactory.
Summary of the invention
The present invention is directed to above-mentioned deficiency, overcome the defect of prior art, two moving contact derailing switches of a kind of efficiently arc extinguishing and protective circuit are provided.
Technical scheme provided by the invention: a kind of pair of moving contact derailing switch, comprise shell, arc control device, contact system and brake apparatus, wherein, contact system comprises the first moving contact and the second moving contact, in arc control device inside, be provided with a pedestal, at pedestal, be provided with fuse, the first moving contact and the second moving contact are respectively from contact both sides or leave fuse, in arc control device, the top of fuse and the first moving contact and the second moving contact is provided with at least two group insulated gate sheets, brake apparatus is located at respectively outside the first moving contact and the second moving contact on one end.
As preferably, fuse is that lead-antimony alloy is made.
As preferably, the first moving contact and the second moving contact are steel electrode material.
Beneficial effect: provided by the invention pair of moving contact derailing switch, rational in infrastructure, be easy to use, utilize two moving contacts and insulated gate sheet, effectively arc extinguishing, and the fuse being provided with can have better protective circuit, very practical.
