Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described Embodiment is a part of embodiment of this utility model, rather than the embodiment of whole.Based on the embodiment in this utility model, this The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality Novel protected scope.

Embodiment 1

As shown in Figure 1, a kind of withdraw-type switch cabinet is it discloses, is standard switch cabinet in the present embodiment, its breaker in middle The overall dimensions of cabinet are width 550mm, high 2000mm, deep 1400mm, and each spaced apart is 150mm；This utility model ground switch cubicle is adopted With air insulation, each electrical safety distance is not less than 125mm；Switch cubicle width ratio ordinary tap cabinet cabinet in the present embodiment subtracts Little 250mm, height reduces 300mm, and the wherein rated current of switch cubicle is 1250A, and busbar specification is 80X10mm.

As shown in Figure 1, the switch cubicle in the present embodiment includes bus-bar room 1, control room 2, breaker chamber 3 and cable vault 4, wherein cable vault 4 is located at the lower section of bus-bar room, and breaker chamber 3 is located at the right side of bus-bar room 1, and control room 2 is located at chopper The upper right corner of room 3.A, B, C phase busbar and the contact box corresponding with each busbar are wherein mainly provided with bus-bar room 1；Each Busbar is respectively provided with main busbar and branch's board, and each main busbar is each passed through bus casing and extends to corresponding touching by branch's busbar Connect at head cartridge, each main busbar is fixed on cabinet respectively by corresponding insulator, and the connection terminal of each main busbar is by solid It is fixed to pass cabinet to the bus casing on cabinet.Wherein be disposed with from the front to the back in bus-bar room 1 respectively with A, B, C phase busbar The contact box of correspondence connection, the connection busbar of A, C phase busbar is placed parallel to front and rear housings, the connection of the B phases busbar Busbar is placed perpendicular to front and rear housings and staggered with A, C phase busbar, and the connection busbar of B phase busbars is arranged at A, C phase busbar Connection busbar between.In order to meet insulating safety distances, the minimum air distance of A, B, C three-phase bus bar is no less than 125mm, because This, branch's busbar of A, C busbar in outside is arranged parallel to the front and rear housings of switch cubicle and effectively reduces front and rear housings Width dimensions, can be reduced to 550mm by common 800mm.

Reduce the arrangement space of ABC phase busbars by above-mentioned setting, make distance and AC phases and housing between ABC three-phases Distance increase guarantee that it has enough insulating safety distances.Meanwhile, integral type transformer is adopted in cable vault 4, therefore take Copper bar coupling part is formed, has made the space of cable vault 4 less, it is ensured that the structure of switch cubicle is compacter, occupation of land space is less, section Substantial amounts of copper bar connecting portion is saved, material cost is reduced.

Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or Among changing the protection domain created still in this utility model.
