The purpose of this utility model is achieved in that
Be applicable to the assembling shunt capacitor that high-frequency induction heating is used, comprise a plurality of independently monomer electric capacity, each monomer electric capacity includes metal shell, electric fuse group, electric exit and cooling water channel copper pipe, the cooling water channel copper pipe is arranged on by the interior electric fuse group of housing, its two ends extend outside the housing respectively, monomer electric capacity improves the radiating effect of monomer electric capacity effectively by setting up the cooling water channel copper pipe on its electric fuse group side; Moreover, described a plurality of independent monomer capacitor fixing is on a metal base, be provided with the common port copper sheet with parallel connection between the electric exit of correspondence on each independent monomer electric capacity, be provided with plastic flexible pipe between the cooling water channel copper pipe end on described each independent monomer electric capacity and connect with the string type mutual conduction.The whole erection process is simple and convenient, and overall structure has increased area of dissipation, is convenient to heat radiation.
The purpose of this utility model can also adopt following technical measures to solve:
As preferred scheme, between described electric exit and the common port copper sheet screw bolt and nut is set and is connected, adopt fixing electric exit of the form that is spirally connected and common port copper sheet, more help convenient installation and both firm connections thereof.
Described monomer electric capacity also is by being bolted on the metal base.
Electric fuse group circumfusion has heat conductive flame-retarding epoxy resin in the described monomer electric capacity housing, more helps heat radiation.
The beneficial effects of the utility model are:
1), assembling shunt capacitor of the present utility model, successively improve by radiator structure to the shunt capacitor after monomer electric capacity and the set thereof, make full use of the cooling water channel copper pipe in the monomer electric capacity, with plastic flexible pipe the cooling water channel copper pipe connection of each monomer electric capacity is ganged up simply, the whole erection process is simple and convenient, and reasonable integral structure has increased area of dissipation, be convenient to heat radiation, applicable to the high-frequency induction heating field;
2), because assembling shunt capacitor of the present utility model, each monomer electric capacity is arranged on the metal base; That is: product design is become modular aggregation type electric capacity, the client is selecting application facet that great convenience is arranged, and standardized component is extensively adopted in the standardization of being more convenient for, and helps promoting the use of of product;
