Description
Technical field
The present invention relates to a kind of cabinet, particularly a steel-clad switchbox with transformer room and fuse handcart.This product is applicable to electric railway 27.5kV traction substation, switching station and section post, is for being switched on or switched off the load current of railway locomotive pulliung circuit, and excision faulty line, guarantees that locomotive traction circuit is all in normal operating condition all the time.
Background technology
At present, the general fast Traction Substation of Electric Railway 27.5kV equipment of China all adopts comparatively traditional net grid interval arrangement, and various single devices are arranged in respectively in the net grid interval in hyperbaric chamber.This arrangement makes equipment room wiring complicated, and device integration is low, and floor space and requisite space are large, installing engineering amount is large, and equipment debugging process is loaded down with trivial details, long construction period, operation maintenance workload is large, and security reliability is relatively low, and can not meet GB GB3906-2006 specification requirement.
Large scale construction and railway system continuous development of the reform along with China's electric railway, proposed requirements at the higher level to the miniaturization of traction power supply equipment, intellectuality, high safety reliability, low maintenance workload etc.Therefore the gas-insulated integrated equipment to high-performance, high-quality, low price, the demand in general fast electric railway is more and more stronger at home, substitutes that traditional net grid interval is arranged that the wiring bringing is complicated, taken up room greatly, the deficiency of low-security etc.
Summary of the invention
The deficiency existing for existing general fast Traction Substation of Electric Railway 27.5kV switchgear, the object of this invention is to provide a kind of steel-clad switchbox with transformer room and fuse handcart, be beneficial to meet GB GB3906-2006 requirement, degree of protection reaches IP4X.The electric connecting mode that adopts handcart-type, conveniently overhauls, and does not affect 27.5KV high-tension circuit normal power supply, realizes service without power-off.
For achieving the above object, the technical solution used in the present invention is to provide a kind of steel-clad switchbox with transformer room and fuse handcart, and this switch cubicle includes control room, fuse handcart chamber, metal clad switchgear cabinet, fuse handcart, transformer, transformer room, main bus bar chamber, fuse handcart chamber pressure relief plate, transformer room's pressure relief plate, bus-bar room pressure relief plate, end of incoming cables fixed contact, leading-out terminal fixed contact, the first main bus bar, the second main bus bar, the first connection copper bar, the second connection copper bar, the 3rd connection copper bar; Wherein: in described metal clad switchgear cabinet, be provided with the control room, fuse handcart chamber, transformer room, the main bus bar chamber that interconnect and separate by metal foil; Described fuse handcart chamber pressure relief plate, transformer room's pressure relief plate, main bus bar chamber pressure relief plate pass through nylon bolt directly and the top board bolt of metal clad switchgear cabinet; Described transformer is arranged on inside, transformer room, and the high pressure inlet wire side of transformer is directly connected copper bar and connects with the 3rd; In described fuse handcart inside, pass through two high-tension fuse integral installations in fuse handcart chamber interior; Handcart end of incoming cables fixed contact connects copper bar through the first connection copper bar, second and is connected with the first main bus bar, the second main bus bar, and leading-out terminal fixed contact is connected with transformer through the 3rd connection copper bar, post insulator.
Effect of the present invention is that cabinet adopts the compacting of aluminizing zine plate assembled formation, and its machining accuracy is 0.2 millimeter, and before overcoming, welding cabinet precision is the deficiency of 1.5 millimeters; And aluminizing zine plate anti-corrosive properties are good, and surface need not apply, before overcoming, welding cabinet falls to paint the phenomenon of getting rusty; Because each circuit arrangement is completed by a cabinet body, in cabinet, high voltage separates not only safety and integrated level but also high with control low-voltage with steel plate, for "smart" products exploitation from now on lays the first stone; Because equipment has all been debugged before dispatching from the factory, bus between an on-the-spot connecting cabinet, therefore install simple and convenient; The fuse handcart of two-phase integrated structure can be realized two-phase electricity line simultaneously, realizes tranformer protection.Adopt machinery and the electric connecting mode of handcart-type, can realize interlocking function, security reliability improves.When there is electric fault, handcart directly can be pulled out to cabinet and overhaul again outward, can realize main bus bar service without power-off.
