Description
Technical field
The utility model relates to half buried box type transformer substation technical field, particularly a kind of lower box structure of half buried box type transformer substation.
Background technology
At present, half buried box type transformer substation is promoted the use of successively, especially in the more and more significantly effect that plays aspect reconstruction of the old city town, new district construction, business busy areas highway layout.This half buried box type transformer substation has conventionally as the top box of switch cabinet chamber with as the lower box of transformer room.On the ground, outer vertical design becomes lamp box advertisement to upper box part operated by rotary motion, and lower box is embedded in below ground.Because the cross section of upper box is less than the cross section of lower box, there is the advantage that reduces floor space.But existing half buried box type transformer substation, due to the unreasonable structure of lower box cover plate, still have following defect: (1) a kind of situation is, the cover plate of lower box is what directly to cover at upper box top, due to construction precision, make cover plate and ground can not guarantee to flush like this.As exceed ground level, and cause the raised area to affect pedestrian, vehicle pass-through, easily cause the accident, injure personal safety, also affect attractive in appearance.In fact also increased floor space.If lower box cover plate, lower than ground level, except above drawback, also can cause the ponding problem of hermatic door on cover plate.Sealing door passes in and out transformer room for maintenance personal, if in long-term immersion, can accelerate the sealing ring that passes in and out on hermatic door aging, and infiltration is to transformer room.(2) another situation is, in erecting bed, on lower box top, constructs pedestal, then (for example: No. 200620065780.9 utility models) on pedestal, adds a cover cover plate.Although this mode can be controlled cover plate and flush with earth's surface, there is the bad problem of waterproof sealing.(3) last, once transformer needs to change, common way is exactly the stube cable first disconnecting on transformer, first hangs and moves upper box, and then hang and move cover plate, could change transformer, causes power-off time long, inconvenient operation, inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of half buried box type transformer substation lower box, can effectively guarantee that cover plate flushes with earth's surface, thereby guarantee that transformer station saves the area, and eliminates again earth's surface potential safety hazard; Can guarantee sealed waterproof effect again, and maintenance is convenient simultaneously.
For addressing the above problem, the utility model relates to half buried box type transformer substation, establishes the upper box of switch cubicle in comprising, the lower box of transformer is inside set.The structure of lower box is: bottom is transformer room, and the top of lower box is upwardly extending for connecting the eck of upper box by one side along its length, the upper surface that remainder is upper box, and the side of upper box is L-type.On upper surface, have upper surface open, size can meet the turnover of transformer, establishes upper surface cover plate in upper surface open.On upper surface cover plate, establish the gathering hole for people's turnover, on gathering hole, establish actuating doors.During practical application, lower box is located under earth's surface, its degree of depth be neck top higher than earth's surface, bottom is lower than earth's surface.Footing foundation is constructed in the periphery of actuating doors, establishes ground cover on footing foundation.Ground cover flushes with ground.Between ground cover and upper surface cover plate, form empty well.
The large I of upper surface cover plate is set according to transformer size, and the position of actuating doors, size also can be adjusted by field requirement.The height on upper surface upper bed-plate basis can be according to on-the-spot actual needs adjustment height.Once occur that increase on road surface or shopping centre transformation, ground cover can regulate at any time and highly keep flushing with ground level, the landscape setting of ground cover also can be made and change according to corresponding requirements.
Preferably, upper surface is the inclined-plane having a down dip to deviating from neck one side.Inclined design can play guide functions to inside, transformer room, be conducive to hot gas guiding to upper box ventilation and heat passage, discharge hot gas: once this design is also beneficial to infiltration in draining empty well, ponding can flow to along inclined-plane empty well bottom, by bottom discharge pipe, import cable trough, form secondary draining preventing mechanism, guarantee the sealing of transformer room.
Preferably, lower box upper surface cover plate is fixed on lower box inclined-plane by bolt seal.
Preferably, the edge of upper surface open is the raised line that a circle makes progress, and there is downward raised line on upper surface cover plate four limits accordingly, makes upper surface cover plate and upper surface open chimeric; Gathering hole and actuating doors are identical fit system.This structure can enter lower box by anti-sealing.
Preferably, the downside of actuating doors and upper surface cover plate are hinged, and handle is established in the top of actuating doors, are convenient to the unlatching of door, and convenient for maintaining personnel, by this passage turnover transformer room, patrol and examine and keep in repair internal unit.
Preferably, the panel of actuating doors adopts transparent material as organic glass manufacture, can double as observation window.
Preferably, gutter is established in empty well bottom, and leads to cable trough.
Preferably, ground cover outer surface can be according to landform, physical features and external environment design, and as far as possible unified mutually with external environment, available various types of materials design, as laid lawn, cobblestone, ceramic tile of all kinds etc.
Compared with prior art, the utility model has the advantages that:
(1) the utility model makes half buried box type transformer substation floor space little, is subject to geographical environment requirement relatively little, can be to greatest extent near load center, and energy-conserving and environment-protective.
(2) upper surface cover plate is designed with and is beneficial to transformer turnover transformer room.Once need to change transformer, can disconnect transformer cable, remove upper surface cover plate and directly hang out failure transformer and carry out equipment replacement.
(3) half buried box type transformer substation of the present utility model can make up civil engineering error and the defect that causes cover plate cannot flush with ground.The height of footing foundation, workmen also can make every effort to guarantee that ground cover flushes with ground level according to on-site actual situations setting, guarantees Pedestrians and vehicles safety and overall appearance.
