Description
Technical field
The utility model relates to half buried box type transformer substation technical field, particularly relates to a kind of half buried box type transformer substation doleiform lower box.
Background technology
At present, half buried box type transformer substation is by constituting as the upper box of switch cubicle chamber with as the lower box of transformer room.The lower box overall structure is square or cuboid usually, is embedded in undergroundly, and built-in transformer, opening part are established cover plate, maintenance window, ventilating opening etc.The cover plate major function is the transformer access way, and the cover plate action pane is imported and exported for the maintenance personal.But there is following shortcoming in such lower box structure: (1) floor space is big, and it is deep to dig the ground degree of depth, is difficult to adapt to complicated underground pipe network environment, has the problem of addressing difficulty; (2) owing to leave maintenance window, supply the staff to pass in and out lower box, sealing problem is difficult to solve; (3) in case transformer breaks down, in the time of must changing, it is very complicated time-consuming then to change the transformer program; Must break off the wiring on the transformer terminal earlier, remove upper box, open cover plate again; The corrupted transformer is hung out the transformer room, so that hang in new equipment; (4) because box cover is horizontal versions, be unfavorable for the water conservancy diversion of thermal current; Narrow ventilating opening is difficult to again the in time efficient lower box of discharging of the heat in the transformer room.
Summary of the invention
In order to overcome the above-mentioned defective of prior art, the utility model provides a kind of doleiform lower box and uses its half buried box type transformer substation.Its neck is embedded in underground with the lower part, ground flushes, and guarantees evenness of road surface, and current safety can guarantee effectively that the lower box floor space is little, and sealing is high, and maintain and replace device simple, thermal current are easy to derive lower box, and waterproof moisture-proof effect is remarkable.
The utility model realizes that the technical scheme of goal of the invention is: a kind of doleiform lower box is provided; Its side elevation is a doleiform; Comprise top neck portion, lower tank body and middle inclined-plane or curved surface shoulder; Chest portion and neck are rectangular shape, and shoulder and neck are an overall structure or are connected with bolt seals that shoulder is connected with bolt seals with chest portion.Lower box has support frame and high-strength corrosion-resisting metallic plate to combine.All handle inside and outside the metallic plate through antirust protection against the tide.
As preferred version, at the cable passage of the left and right sides of neck arranged outside above-below direction.
As preferred version, absorb heat the in addition speciality of waterproof of the inner wall of the doleiform lower box fire-retardant acoustical cotton that distributes unevenly, this kind material further reduces the noise of transformer.
The utility model also provides a kind of half buried box type transformer substation that uses above-mentioned doleiform lower box.This half buried box type transformer substation comprises: as the upper box of switch cubicle chamber, be placed with switch cubicle in it; As the doleiform lower box of transformer room, its underpart chest portion is placed with transformer.The neck part of lower box is basseted, and remainder buries ground, and ground level flushes does not establish other gateways or facility.The neck space is vent passages and maintenance channel.At least one facade of upper box is established door, and the inner space of this interior upper box communicates with neck opening.The maintenance personal can directly get into lower box from neck opening by this door.
As preferred version, the ventilation compartment of up/down perforation is set in upper box, lead to lower box, both be the air duct of lower box, also be the passage that personnel pass in and out lower box.The door of personnel's turnover is set at the ventilation compartment in the outer part.
As preferred version, upper box left and right sides yardstick equates with the yardstick that lower box comprises the neck cable passage.Cable passage top feeds upper box, the joint portion sealing; The bottom of cable passage feeds cable trough.This cable passage constitutes the air duct of switch cubicle chamber simultaneously.
As preferred version, the joint portion of lower box is provided with the ventilating opening of lower box on the side of front and back.
As preferred version, lower box neck open country height interval is 300-700mm, sets according to the installation region precipitation event, guarantees the city under the waterlogging situation, and ponding can't get into lower box, and transformer can safe operation.
The Seal Design of doleiform lower box overall structure and cable passage has guaranteed the whole box body sealing, prevents that ponding from infiltrating the transformer room, guarantees the transformer safe operation.
Doleiform lower box structural design has made full use of the neck space; As heat-dissipating space; Avoided traditional half buried box type transformer substation between last lower box, to reserve special heat dissipation channel, made the whole lower box degree of depth can reduce 250-500mm at least, reduced and bury the ground degree of depth.The inclined-plane of its shoulder or curved design help hot gas is guided to ventilating opening, improve the natural draft radiating efficiency.
Doleiform lower box structural design has made full use of the neck space; This neck opening place is provided with maintenance channel; Convert the maintenance window of externally positioned type into the internally-arranged type maintenance channel, guaranteed the sealing of transformer room, reduced that also the floor space that maintenance window enlarges being set; Further reduce floor space, be beneficial to construction transformer station.
Doleiform lower box structural design is connected with chest portion shoulder with bolt seals.In case break down in the transformer room, when need changing, then break off the line on the transformer, unclamp bolt, chest portion is comprised that with top upper box integral body hangs out, change transformer, maintenance efficiency is higher relatively, easy operating.
Compared with prior art, the utility model has the advantages that:
Neck dwindles, and the bottom is designed with burying and reduced floor space, has also guaranteed the safe passing of Pedestrians and vehicles, has also guaranteed the attractive in appearance of integral body; Good airproof performance has strengthened water resistance; The air discharging and radiating effect improves; Reduced noise.
