Description
Technical field
The present invention relates to a kind of cabinet, particularly a kind of overhead outlet of armored metal enclosed switchgear and loading switch cabinet.This product is applicable to electric railway 27.5kV traction substation, switching station and section post, is the load current that is used for being 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 arrangement at interval, and promptly various single devices are arranged in respectively in the net grid interval hyperbaric chamber in.This arrangement makes equipment room wiring complexity, and device integration is low, and floor space and requisite space are big, the installing engineering amount is big, and the equipment debugging process is loaded down with trivial details, long construction period, the operation maintenance workload is big, and security reliability is relatively low, and can not satisfy GB GB3906-2006 specification requirement.
Along with the 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 the general at home fast electric railway is more and more stronger.
Summary of the invention
Deficiency at existing general fast Traction Substation of Electric Railway 27.5kV switchgear existence, the overhead outlet and the loading switch cabinet that the purpose of this invention is to provide a kind of armored metal enclosed switchgear, be beneficial to satisfy GB GB3906-2006 requirement, degree of protection reaches IP4X, realize effective anti-error function, the security reliability height.
For achieving the above object, the technical solution used in the present invention provides a kind of overhead outlet and loading switch cabinet of armored metal enclosed switchgear, and wherein: this switch cubicle includes control room, metal clad switchgear cabinet, on-load switch, on-load switch chamber, main bus bar chamber, main bus bar chamber pressure relief plate, on-load switch chamber pressure relief plate.
Be provided with control room, on-load switch chamber, the main bus bar chamber of mutual electrical connection in the described metal clad switchgear cabinet, control room, on-load switch chamber, main bus bar separate by metallic plate between the chamber; The on-load switch chamber is connected with on-load switch; Be respectively equipped with on-load switch chamber pressure relief plate, main bus bar chamber pressure relief plate on on-load switch chamber, the main bus bar chamber, on-load switch chamber, main bus bar chamber are equipped with the arc stream pressure release passage, and the passway is located at the top of cabinet; Described on-load switch connects copper bar by first and is connected with the main bus bar of main bus bar chamber, and main bus bar is connected with main bus bar simultaneously; Described on-load switch connects copper bar by second and is connected with interbus.
Effect of the present invention is to cover compacting of aluminium zine plate and assembled formation because cabinet adopts, and its machining accuracy is 0.2 millimeter, and welding cabinet precision is 1.5 millimeters a deficiency before overcoming.And it is good to cover aluminium zine plate anti-corrosive properties, and the surface need not apply, and the welding cabinet falls to coat with lacquer the phenomenon of getting rusty before overcoming.Because each circuit arrangement is all finished by a cabinet body, high voltage separates not only safety and integrated level but also high with the control low-voltage with steel plate in the cabinet, for "smart" products exploitation from now on lays the first stone.Because equipment has all been debugged before dispatching from the factory and finished, the scene only connects bus between cabinet, so install simple and convenient.Because copper busbar is all overlapped insulating sleeve, has improved margin of safety more than 15%, can reduce bus cleaning maintenance or non-maintaining.
Description of drawings
Fig. 1 is the overhead outlet and the loading switch cabinet structural representation of armored metal enclosed switchgear of the present invention;
Fig. 2 is the primary circuit sketch of armored metal enclosed switchgear of the present invention.
Embodiment
Reaching enforcement in conjunction with the accompanying drawings is illustrated the overhead outlet of armored metal enclosed switchgear of the present invention and the structure of loading switch cabinet.
As shown in Figure 1, 2, the overhead outlet of armored metal enclosed switchgear of the present invention and loading switch cabinet, this switch cubicle include control room 1, metal clad switchgear cabinet 2, on-load switch 4, on-load switch chamber 5, main bus bar chamber 9, main bus bar chamber pressure relief plate 10, on-load switch chamber pressure relief plate 13.
Be provided with control room 1, on-load switch chamber 5, the main bus bar chamber 9 of mutual electrical connection in the described metal clad switchgear cabinet 2, separate by metallic plate between control room 1, on-load switch chamber 5, the main bus bar chamber 9; On-load switch chamber 5 is connected with on-load switch 4; Be respectively equipped with on-load switch chamber pressure relief plate 13, main bus bar chamber pressure relief plate 10 on on-load switch chamber 5, the main bus bar chamber 9, on-load switch chamber 5, main bus bar chamber 9 are equipped with the arc stream pressure release passage, and the passway is located at the top of cabinet 2; Described on-load switch 4 connects copper bar 3 by first and is connected with the main bus bar 11 of main bus bar chamber 9, and main bus bar 11 is connected with main bus bar 11 simultaneously; Described on-load switch 4 connects copper bar 7 by second and is connected with interbus 6.
