Specifically, described fixture can be one group of insulating guide rail, use insulated bolt to be anchored in power cabinet housing, can mount and dismount easily like this, what described module support part was concrete can be the sheet material that insulating material is made, but from being beneficial to the angle of heat radiation, more preferably select the structure that can ventilate, in a preference of the present invention, module support part consists of insulate crossbeam and insulation vertical beam, insulation crossbeam is arranged with insulation vertical beam square crossing, has been taken into account fastness and heat radiation.
In actual use, can determine according to SVG actual capacity demand the number of plies of module mounting layer, preferred, the number of plies of module mounting layer can be 5-9 layer.
Preferably, the top of cabinet housing can also arrange suspension ring, and suspension ring are fixed on cabinet housings support beam, can realize power cabinet integral hoisting, and convenient transportation and engineering site assembling, adopt bolt type fastening.
The bottom of preferred cabinet housing is also reserved with insulator installing hole.
Insulating material in the present invention can require to determine according to the actual class of insulation, specifically, can select epoxy laminate goods, epoxy-mica goods, epoxy glass fabric vacuum pressure gumming product, epoxy glass fiber dipped article or epoxy resin fiberglass winding product etc., those skilled in the art should be able to be according to selecting existing insulating material according to actual demand.
The invention has the advantages that:
1, power cabinet overall structure is attractive in appearance, and floor space is less, better to module protection, and service behaviour is comparatively stable;
2, insulating material is combined with metal material, has saved cost when effectively improving SVG operation stability;
3, module mounting layer adopts drawer-type structure design, and compact conformation is convenient to install;
4, special air duct is set, blower fan adopts back hanging type, according to heat dissipation capacity, suitably selects blower fan, and module is divided into groups to dispel the heat, and is beneficial to the realization of large heat dissipation capacity;
5, top arranges hoisting ring device, can realize power cabinet integral hoisting, convenient transportation and engineering site assembling.
