Technical field
The utility model relates to a kind of cabinet, particularly a kind of steel-clad switchbox with overhead outlet.This product is applicable to electric railway 27.5kV traction substation, switching station and section post, is the load current that is switched on or switched off the railway locomotive pulliung circuit, and the excision faulty line guarantees that the locomotive traction circuit all is 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 intervals arrangement, and namely various single devices are arranged in respectively in net grid interval in the hyperbaric chamber.This arrangement makes the equipment room wiring complicated, and device integration is low, and floor space and requisite space are large, the installing engineering amount is large, and the equipment debugging process is loaded down with trivial details, long construction period, the operation maintenance workload is large, and security reliability is relatively low, and can not satisfy GB GB3906-2006 specification requirement.
Along with Large scale construction and the railway system continuous development of the reform of China's electric railway, requirements at the higher level have been proposed for the miniaturization of traction power supply equipment, intellectuality, high safety reliability, low maintenance workload etc.Therefore to the gas-insulated integrated equipment of high-performance, high-quality, low price, the demand in general fast electric railway is more and more stronger at home.
Summary of the invention
Deficiency for existing general fast Traction Substation of Electric Railway 27.5kV switchgear existence, the purpose of this utility model is to provide a kind of steel-clad switchbox with overhead outlet, be beneficial to satisfy GB GB3906-2006 requirement, degree of protection reaches IP4X, realize the interlocking function, security reliability is high., can be connected on draught line from traction substation is built on stilts very easily above railway due to the electric railway traction electric wire.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of steel-clad switchbox with overhead outlet, and wherein: this switch cubicle includes control room, metal clad switchgear cabinet, electric isolating switch, isolating switch chamber, main bus bar chamber, main bus bar chamber pressure relief plate, isolating switch chamber pressure relief plate.
Be provided with interconnective control room, isolating switch chamber, main bus bar chamber in described metal clad switchgear cabinet; Control room, isolating switch chamber, main bus bar separate by metallic plate between the chamber; The attaching of isolating switch chamber has electric isolating switch; Be respectively equipped with isolating switch chamber pressure relief plate, main bus bar chamber pressure relief plate on isolating switch chamber, main bus bar chamber; Isolating switch chamber, main bus bar chamber is equipped with the arc stream pressure release passage, and the passway is located at the top of cabinet; Described electric isolating switch connects copper bar by first and is connected with the main bus bar of main bus bar chamber; Electric isolating switch is connected with overhead outlet through post insulator simultaneously; Described electric isolating switch connects copper bar by second and is connected with interbus.
Effect of the present utility model is to cover the compacting of aluminium zine plate and assembled formation because cabinet adopts, and its machining accuracy is 0.2 millimeter, and before overcoming, welding cabinet precision is the deficiency of 1.5 millimeters.And it is good to cover aluminium zine plate anti-corrosive properties, and the surface need not apply, and before overcoming, the 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 the control low-voltage with steel plate, for "smart" products exploitation from now on lays the first stone.All debugged before dispatching from the factory due to equipment and completed, bus between an on-the-spot connecting cabinet is therefore install simple and convenient.Because copper busbar is all overlapped insulating sleeve, improved margin of safety more than 15%, can reduce bus cleaning maintenance or non-maintaining., can be connected on draught line from traction substation is built on stilts very easily above railway due to the electric railway traction electric wire.
Description of drawings
Fig. 1 is the steel-clad switchbox structural representation with overhead outlet of the present utility model;
