Outside ringing very greatly, the most easily making conductor metal surface oxidation, the oxide of generation makes again contact resistance increase and affects returning of chopper
Road resistance and electric property, temperature rise simultaneously is excessive also can make insulating part dielectric loss increase, and accelerates the aging of insulating part.How
The temperature rise effectively reducing vacuum circuit breaker attracts widespread attention.
Remaining Xiao Lings etc. (high-voltage electrical apparatus, the 3rd phase of volume 43 in June, 2007) have carried out high-pressure vacuum breaker temperature rise impact
The simulation study of factor, its heat-delivery surface convection transfer rate on affecting vacuum circuit breaker temperature rise, dynamic/static contact contact thirty
4 kinds of factors such as the radius of footpath, contacting points position and conducting rod have carried out simulation study, the heat radiation of spreader surface, touch
The radius of head radius and conducting rod all has certain effect to reduction temperature rise.CN2747699Y discloses one and has high specified electricity
The high-pressure vacuum breaker of stream grade, it includes the first radiator being connected with upper flange, is provided around second at lower flange and dissipates

On the basis of his performance, effectively reduce temperature rise.
Above-mentioned vacuum circuit breaker during fabrication, prepares graphene layer at each parts surface of radiator joint face and/or galvanic circle,
It is then assembled into vacuum circuit breaker,.Preferably, at upper wiring board, static conductive rod, moving conductive rod and the table of lower patch panel
The joint face of face and/or radiator prepares graphene layer, is assembled into vacuum circuit breaker,.
The method that can use spraying, brushing or dip-coating prepares graphene layer.When using spraying coating process, conduct electricity at vacuum circuit breaker
The each parts surface in loop, radiator sprays a layer graphene on the joint face of upper wiring board, dries or at 50 DEG C～300 DEG C
Under dry.When using brush coating process, at each parts surface in vacuum circuit breaker galvanic circle, radiator and upper wiring board
Brush a layer graphene on joint face, dry or dry at 50 DEG C～300 DEG C.When using dipping process, by vacuum
The each parts in chopper galvanic circle, the joint face of radiator and upper wiring board immerses in Graphene slurry, takes out, dry or
Dry at 50 DEG C～300 DEG C.
Graphene slurry used by spraying, brushing or dip-coating can use commercial goods.Preferably, the quality hundred of Graphene slurry
Proportion by subtraction consists of: solvent 70%～95%, Graphene 4.5%～27%, dispersant 0.5%～3%.By each component at a high speed
Be uniformly dispersed under dispersing apparatus to obtain Graphene slurry.
