Description
Technical field
The invention belongs to switching technique fields, are specifically exactly to be related to a kind of limitation arc path of rotary separation switch
Module and the rotary separation switch.
Background technique
The word explanation of switch is to open and close.It refers to that one can make open circuit, make current interruptions or make it
Flow to the element of other circuits.The most common switch is the electromechanical equipment for allowing people to operate, wherein there is one or several contacts.Contact
" closed " (closed) indicate contact conducting, allow electric current flow through；" open circuit " (open) of switch indicates that contact is not turned on shape
At open circuit, electric current is not allowed to flow through.The developing history of switch is developed to from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electrics control equipment, the function of switch is more and more, and safety is also got over
Come higher, rotary switch is a kind of common switch, by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding specific position of state is determined to prevent rotary operating device from being operated without permission.Rotary isolation switch is widely applied
In electric system, for example, photovoltaic, wind-powered electricity generation etc..Such as in photovoltaic system, the lesser electric current that is generated in each photovoltaic cell
It is combined in parallel so as to the electric current or general power needed for being provided using system.
Usual rotary isolation switch can generate electric arc when dynamic/static contact separates, and dynamic/static contact is from closed position to separately
There is a space between position, this space is made of insulating part, and electric arc does random movement, electric arc meeting in this space
Surface of the ablation Jing Guo material, insulation performance can reduce after these materials are ablated, and repeatedly insulation effect can fail later, from
And it will lead to failure of insulation or service life reduction.When the power of disjunction increases, the distance between general increase dynamic/static contact, or
Person reinforces the material around contact to realize safe disjunction.But this way certainly will increase the volume of electric switch, increase more
More materials meets the condition of arc extinction.
