Description
Technical field
The invention belongs to switching technique field, is exactly specifically to be related to a kind of rotary isolation provided with twin channel outlet gas port
Switch contact module.
Background technology
The word explanation of switch is opening and closing.It refers to that one can make open circuit, make current interruptions or make it
Flow to the element of other circuits.Most common switch is the electromechanical equipment for allowing people to operate, wherein having one or several contacts.Contact
" closed " (closed) represent contact conducting, it is allowed to electric current flows through；" open circuit " (open) of switch represents that contact is not turned on shape
Into open circuit, electric current is not allowed to flow through.The developing history of switch develops into from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electric control devices, the function of switch is more and more, and security is also got over
Come higher, rotary switch is a kind of common switch, and it is by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding ad-hoc location of state is determined to prevent rotary operating device from being operated without permission.Rotary isolation switch is widely applied
In power system, for example, photovoltaic, wind-powered electricity generation etc..Such as in photovoltaic system, caused less electric current in each photovoltaic cell
Combined in parallel to provide required electric current or general power to using system.
In existing photovoltaic system, generally realized using rotary isolation switch and individually isolate, protect and disconnect each light
Lie prostrate the purpose of battery.At present, be commonly used in photovoltaic system rotary separation switch include an operating mechanism and it is some touch
The structures shape of head module, wherein contact module the arc quenching effect of disconnecting switch, and existing contact module is rotatably being isolated
Switch moving contact component and static contact component engagement or disengage when can produce arc discharge, if electric arc can not quickly extinguish or
Rotary separation switch is left, the interrupting performance of rotary separation switch will be reduced, causes the generation of security incident.It is existing
For the moving contact of rotary separation switch when separating brake moves to stop position, electric arc disposably can be discharged to disconnecting switch from gas outlet
Outside, finally extinguish electric arc.Current disconnecting switch have in the gas outlet of side (close to moving contact separating brake rest position) and
Only one, if the gas outlet is opened too much, it is unfavorable for saving bit by bit enclosure interior air pressure, that is, is unfavorable for being lifted the motion of electric arc
Speed；If open it is too small if be unfavorable for electric arc and be discharged to outside in time.
The content of the invention
The purpose of the present invention existing is applied to photovoltaic industry high voltage appearance and high current electrical system aiming at above-mentioned
In rotary separation switch during being switched on or switched off caused electrical discharge arc outlet be unfavorable for electric arc exclusion technology
Defect, there is provided a kind of rotary separation switch contact module provided with twin channel outlet gas port, close to moving contact separating brake stop position
The place of putting gas outlet is divided into two outlet passageways, first outlet passageway the also non-separating brake of moving contact in place when, just will part electricity
Arc is discharged to hull outside；Remaining electric arc is discharged to hull outside by second outlet passageway when moving contact moves in place.It is double
The structure of passage gas outlet not only contributes to lift enclosure interior air pressure, accelerates arc motion speed, is also discharged in time for electric arc
Passage is provided, and then greatly improves the arc extinction performance of disconnecting switch.The final breaking capacity lifting for causing disconnecting switch, is protected
The security performance that rotation fitting type disconnecting switch uses is demonstrate,proved.
