Abstract
A rotating contact arc extinguishing chamber comprises an outer shell, a fixed contact, a rotating disc and at least one movable contact arranged on the rotating disc. The two sides of the fixed contact are respectively provided with a side plate. Air jet holes are formed between the side plates and the fixed contact and formed in the inner wall of the arc extinguishing chamber. The air jet holes are connected with air bags outside the arc extinguishing chamber. The two sides of the portion between the rotating disc and the fixed contact are provided with insulated gates. The rotating contact arc extinguishing chamber is reasonable in structure, on the basis of the compressed gas and insulated gate arc extinguishing principle, gas arc extinguishing and insulated gate arc extinguishing are combined, the arc extinguishing performance is efficiently achieved, and the purpose of protecting an electric appliance is achieved as much as possible.
Description
Technical field
The present invention relates to a kind of arc control device.
Background technology
Switch, when opening or cutting out, can make air ionization, produces electric arc, and to switch and around cause damage, so switch arc-control device is the critical component effectively addressing this problem.Arc quenching principle based on different, the Structural Tectonics of arc control device is not identical yet, in present technology, how according to different arc quenching principles, to adopt single arc extinguishing structure, causes the poor efficiency of arc-suppression function, can not reach better arc quenching effect.
Summary of the invention
The present invention is directed to above-mentioned deficiency, overcome the defect of prior art, a kind of rotary contact arc control device of efficiently arc extinguishing are provided.
Technical scheme provided by the invention: a kind of rotary contact arc control device, comprise shell, fixed contact, rotating disk and be located at least one moving contact on rotating disk, wherein: in fixed contact both sides, be respectively provided with a side plate, between side plate and fixed contact, be provided with puff prot on arc control device inwall, puff prot is connected with the air bag in arc control device outside, and the both sides between rotating disk and fixed contact are provided with insulated gate sheet.
As preferably, the gas of filling in air bag is hydrogen, hydrogen-nitrogen mixture gas or SF
6gas.
As preferably, arc control device inner side is coated with insulation resistance to compression resin bed.
Beneficial effect: rotary contact arc control device provided by the invention, rational in infrastructure, utilize Compressed Gas and insulated gate sheet arc quenching principle, gas arc extinguishing and insulated gate sheet arc extinguishing are combined, reach efficiently the performance of arc extinguishing, reach as much as possible the object of protective device.
