Abstract
A power switch comprises a static contact, a movable contact, an arc extinguish chamber, a metal gate and an outer wall, wherein the metal gate is arranged between the static contact and the movable contact, a round notch is formed in the metal gate, an electricity-conductive aluminum film is plated on the rest surface of the metal gate, a spring device is arranged at the part, extending towards the outer side of the arc extinguish chamber, of the movable contact, the spring device comprises a fixed ring, a spring and a base, and the base and the fixed ring are connected through a buckle. The power switch is reasonable in structure and easy to use, the movable contact can be switched off rapidly, and the metal gate plated with the film can effectively extinguish arc, is resistant to corrosion, and is favorable for long-term use.
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, opening or while cutting out, can making air ionization, produces electric arc, and to switch and around cause damage, therefore the validity of switch arc-control device is the critical component addressing this problem.With metal gate sheet, carry out arc extinguishing, electric arc is formed to multiple short electric arc, further eliminate electric arc, can reduce electric arc harm, but comparatively serious to the corrosion of metal gate sheet, can cause for a long time arc extinguishing decrease in efficiency, impact is used.
Summary of the invention
The present invention is directed to above-mentioned deficiency, overcome the defect of prior art, a kind of effectively electric power switch apparatus of arc extinguishing is provided.
Technical scheme provided by the invention: a kind of electric power switch apparatus, comprise fixed contact, moving contact, arc control device, metal gate sheet and outer wall, wherein: metal gate sheet is located between fixed contact and moving contact, on metal gate sheet, be provided with circumferential notch, remaining surface is coated with one deck conductive aluminum film, the part that moving contact extends to arc control device outside is provided with a spring assembly, and spring assembly comprises retainer ring, spring and pedestal, and pedestal is connected by buckle with retainer ring.
As preferably, metal gate sheet is vertical bar type or U-shaped.
As preferably, metal gate sheet is 3-7 sheet.
As preferably, metal gate sheet is that thickness is 0.5-1.5mm.
Beneficial effect: electric power switch apparatus provided by the invention, rational in infrastructure, be easy to use, moving contact can disconnect fast, effectively arc extinguishing of plated film metal gate sheet, and also corrosion-resistant, be beneficial to long-term use.
