Description
Technical field
The utility model belongs to middle pressure dressing aluminium zine plate solid-state start technical field, is specifically related to the solid-state soft starting device of pressure dressing aluminium zine plate in one.
Background technology
At present, traditional middle pressure soft cabinet, cabinet material is generally cold-rolled steel sheet and makes, and the core component power control unit of soft needs fixed installation.Cold-rolled steel sheet welding cabinet requires higher to the weld horizontal of workman, easily distortion after welding, and cabinet such as to get rusty easily at the shortcoming; Power control unit volume generally adopts fixed installation, because volume is larger, heavier, needs two or more people to install.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the solid-state soft starting device of pressure dressing aluminium zine plate in one, has volume little, compact conformation, easy for installation, changes feature easy to maintenance.
For achieving the above object, the technical solution adopted in the utility model is: the solid-state soft starting device of pressure dressing aluminium zine plate in one, include cabinet, in cabinet base plate is provided with from left to right successively, be provided with inlet wire cable, contactor, lightning arrester, current transformer, outlet cable; The outside of outlet cable is provided with zero-sequence transformer; The upper end of outlet cable is connected with insulation column; Inlet wire cable is connected to the end of incoming cables of contactor and power control unit, after the leading-out terminal of power control unit is connected by copper bar with the leading-out terminal of contactor, be connected on insulation column by lightning arrester, current transformer by copper bar, outlet cable passes zero-sequence transformer to exterior motor after being connected to outlet copper bar; Inlet wire cable is connected with transducer, fuse, voltage transformer respectively; The right side of voltage transformer is provided with control room.
Described inlet wire cable and outlet cable to enter in cabinet from bottom of cabinet bulk and are connected with line copper bar.
Described power control unit is withdrawable structure, power control unit is fixing on a chassis, in the middle of cabinet, chassis vehicle track is equipped with in both sides, by the power control unit that transport carriage will fix, advance in cabinet by track, chassis vehicle auto lock, fixes the line copper bar of power control unit.
The beneficial effects of the utility model are:
Cabinet adopts aluminizing zine plate, and power control unit adopts withdrawable structure.Aluminizing zine plate has excellent corrosion resistance, and useful life can for 25 years, and aluminizing zine plate cabinet is modular construction, except door-plate, all the other are all splicing package assembly, can greatly reduce cost of labor, consistency after assembling is also relatively good, can well meet the requirements such as same switch cabinet combining; Power control unit is withdrawable structure, and power control unit is fixed on ground jiggering, and in the middle of cabinet, chassis vehicle track is equipped with in both sides, advances in cabinet, chassis vehicle auto lock by track.Change cabinet material, add service life of equipment, power control unit changes into withdrawable, is convenient to install and after-sales service.
Compared with prior art, the utility model has that volume is little, compact conformation, fail safe are high, easy for installation, the features such as long service life.
Accompanying drawing explanation
