Description
Technical field
The invention belongs to switching technique field, is exactly specifically to be related to a kind of rotary separation switch with increasing magnetic patch to touch
Head 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.In order to carry
The high electric arc velocity of discharge, is usually the effect for reaching arc extinguishing using magnet structure form in present disconnecting switch, but this knot
Structure is unfavorable for electric arc towards identical form according to permanent magnet and is discharged to hull outside, using permanent magnet towards different structure shapes
Formula sense of current in wiring requires, and causes installation inconvenience.
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 the rotary separation switch purpose that caused electrical discharge arc is discharged using permanent magnet during being switched on or switched off be difficult to reach
The technological deficiency arrived, there is provided it is a kind of with the rotary separation switch contact module for increasing magnetic patch, by rotary separation switch
Inside set up increasing magnetic patch, using increase magnetic patch by electric arc discharge rotary separation switch housing, not only increase and rotatably keep apart
The arc quenching effect of pass, while the directionless requirement of no current is installed, installation difficulty is reduced, ensure that rotation fitting type disconnecting switch uses
Security performance.
Technical scheme
