Along with the fast development of urban construction, high-tension electricity is applied and is increased gradually in city, become the restriction of floor space owing to being subject to urban construction transformer station and case, the demand of miniaturized power transformation miniaturized high-tension switch cabinet is in one's power increasing, especially in 40.5KV wind-powered electricity generation and photovoltaic project.It is particularly important that the small form factor requirements realizing 40.5kV indoor alternating current high voltage vacuum load switch-fuse combined electrical equipment shows.
Utility model content:
The purpose of this utility model is to provide a kind of parallel support formula pole, to realize the small form factor requirements of 40.5kV indoor alternating current high voltage vacuum load switch-fuse combined electrical equipment.
To achieve these goals, the utility model adopts following design: a kind of parallel support formula pole, comprises epoxy resin housing, electric field shielding cover, parallel support threaded connector, copper conducting rod, copper insert, vacuum interrupter, arc control device supporting bracket, pin, conductive nut; Described pole is vertically fixed between the entablature of combined electrical apparatus and middle cross beam by mounting screw; Described vacuum interrupter sealing is in epoxy resin housing, and its top is connected with copper conducting rod by conductive nut; Described copper conducting rod and copper insert are welded to connect, and are cast in epoxy resin housing after being connected with vacuum interrupter; Be cast in after described electric field shielding cover is connected with parallel support threaded connector in epoxy resin housing; Described arc control device supporting bracket and pin are welded to connect, and are cast in epoxy resin housing with embedded platy structure.
Preferred: described pole adopts parallel support formula installed surface to be parallel to vacuum interrupter and major loop copper conducting rod is fixed between the entablature of combined electrical apparatus and middle cross beam, but not adopts traditional punching structure, improves being uniformly distributed of high voltage electric field.
Preferred: described arc control device supporting bracket adopts embedded parallel planar structures, gained in strength by pin welding, and be cast in epoxy resin housing, make whole pole one integrated mass, simple and reliable, installation accuracy is high.
Preferred: described pole adopts modular construction, when pouring into a mould the epoxy resin housing of High aititude, only need lengthen at end sections, a secondary mould can be shared with standard height above sea level pole, reduce production cost.
The utility model has following beneficial effect: the utility model by vacuum interrupter and copper conducting rod sealing in epoxy resin housing, reduce the volume of vacuum load switch-fuse combined electrical equipment, an arc control device supporting bracket part is cast in epoxy resin housing, make whole switch more miniaturized, layout is compacter.Electric field shielding cover is cast with in pole, the parallel support threaded connector be connected with electric field shielding cover and screw fit, be parallel to vacuum interrupter with parallel support formula installed surface and major loop copper conducting rod is fixed between the entablature of combined electrical apparatus and middle cross beam, solve the problem of pole inner high voltage non-uniform electric.This parallel support formula pole has good insulation level, saves number of spare parts and raw material, reduces production cost.
