Half buried box-type substation
Technical field
The utility model belongs to transformer station's technical field of electrical power trans mission/distribution system, relates to a kind of half buried power transformation case, is applied to the transmission and distribution network and the terminal electric power systems such as urban operating mechanism, industrial park, biotope, building in city.
Background technology
Box-type substation is a kind of outdoor power transmission and distribution facility of compact composite type that integrates transformer, high and low voltage switch cabinet.Box-type substation mainly contains three class formation modes: (1) full console mode; (2) half is buried; (3) buried.Compare with being installed in the ground box-type substation that lands entirely, half buried box type transformer substation has been imbedded the part operation casing underground, effectively reduce the face of land height of box-type substation, part has solved lands entirely that the floor space of box-type substation is big, addressing falls the position difficulty, noise is big, influences defective such as view; Complete buried box-type substation does not then take spatial surface fully, have do not influence that look of the city, civilwork engineering quantity are little, degree of protection is than advantages such as height.But complete buried box-type substation need be provided with ventilation hole and manhole, more general problem below the existence: (1) does not generally have strict waterproof seal or measure because of its structural body and box cover, therefore box cover and air vent hole must be arranged on more than the ground, so just can not eliminate the problem of view harmony and noise pollution.(2) if ventilation hole, manhole, manhole and box cover are made integral structure, there is the junction sealing problem too, and strengthened the complexity of manufacturing, installation; (3) if respectively ventilation hole, manhole, manhole are set, it is too much to cause buried case to become the structural member that extends to ground; (4) buried case becomes when regular works such as carry out that operating condition inspection, metering are checked meter, and must enter the casing operation from manhole, the working strength height, and fail safe and operability are relatively poor.Therefore, dissimilar traditional box-type substations all exists addressing fall many defectives and deficiencies such as position difficulty, poor, the outer facade of landscape effect is safeguarded and renovation difficulty, noise be excessive, is difficult to satisfy the demand of urban construction and development.
Summary of the invention
The utility model is at the shortcomings and deficiencies of traditional box-type substation, provide a kind of structural strength height, antifreeze, anticracking, anti-corrosion property good, safe and reliable to operation, landscape effect is good, convenient for installation and maintenance, noise is low, half buried box power transformation case of environmental protection.Can satisfy the environment located in residential quarters, municipal park, commercial highway section etc., safety, with the view requirement, improve the urban power distribution network class.
Half buried box power transformation case comprises aerial part, under ground portion, base part and box top branch.Box top branch, aerial part, base part and under ground portion are linked in sequence and are one.
Aerial part is a body structure, and bottom, casing both sides is symmetrical arranged ventilation shutter respectively, the instrument observation hole; Top, casing both sides is symmetrical arranged the instrument observation hole respectively, has been horizontally disposed with division board in the casing.
Under ground portion is an enclosed construction, and transformer is installed in the under ground portion, and the bus of transformer is connected with the switch of aerial part through enclosed type waterproof bus passage with the inlet wire cable, and described enclosed type waterproof bus passage is arranged on the top of under ground portion.One sidewall of under ground portion is provided with the step ladder, and the bottom of under ground portion is provided with the ball-cock assembly water pump.
Base part is between aerial part and under ground portion, and base part is provided with the hanger that the lifting under ground portion is installed for four jiaos.
The box top is divided into the slope roof construction, and the top that the box top is divided is provided with ventilation slot, and ventilation slot is provided with blower fan.The Wai Dingchu that the box top is divided is provided with and equips the solar energy tabula rasa.
The utility model compared with prior art, the performance of its advantage and beneficial effect is:
1. the operation control section with box change is retained in aerial part, and its main part is all imbedded underground, and floor space is little, and face of land height is low, has reduced noise and electromagnetic radiation that case becomes effectively.
2. the box top is divided into the independent modular construction that can match, and appearance and modeling can suit measures to local conditions to select different architectural styles according to environment, and view harmony is good.
3. the box top branch can be installed solar panel.Case change positive and negative can be installed by LED display or landscape ornamental throws light on, emergence lighting lamp, and its power supply can be become the solar energy control cubicle output of configuration, energy-conserving and environment-protective by case.

Embodiment
As shown in Figure 1, half buried box power transformation case comprises that aerial part 2, under ground portion 4, base part 3 and box top divide 1.The box top divides 1, aerial part 2, base part 3 and under ground portion 4 are linked in sequence is one.The steel plate making that material can adopt corrosion resistant plate, aluminium alloy plate and handle through surfacecti proteons such as pitch, plexiglas fiber, sprayings.
As shown in Figure 2, aerial part 2 is a body structure, and bottom, casing both sides is symmetrical arranged ventilation shutter 2-1 respectively; Top, casing both sides is symmetrical arranged instrument observation hole 2-3 respectively, has been horizontally disposed with division board 2-2 in the casing.Be furnished with gauge table, inlet wire high-voltage switch gear, low pressure master switch, thermostat, ammeter, low-voltage bus bar, low tension switch, solar storage battery, controller for solar, capacitor and high-tension switch cabinet in the aerial part; Casing is established division board makes high and low voltage chamber separately.
As shown in Figure 3, under ground portion 4 is the body structure of sealing, transformer 4-3 is installed in the under ground portion 4, the bus of transformer 4-3 is connected with the switch of aerial part through enclosed type waterproof bus passage 4-1 with the inlet wire cable, and described enclosed type waterproof bus passage 4-1 is arranged on the top of under ground portion.One sidewall of under ground portion is provided with terraced 4-2 of step, and the bottom of under ground portion is provided with ball-cock assembly water pump 4-4; Immersion, the water surface surpass pedestal, rainwater pours into the time-sharing automatic triggering drainage system of underground part when urban drainage pipe network does not freely cause, and make pump working and discharge ponding.
Base part 3 is between aerial part and under ground portion, and base part is provided with the hanger 3-1 that the lifting under ground portion is installed for four jiaos.The ground connection steel plate 3-2 of base part reliably is connected with the aerial part casing with under ground portion, case is become have good ground connection lightning protection properties.In addition, base part is the plane above Ground, to prevent that rainwater from entering under ground portion, and be provided with the waterproof interface, rainwater with aerial part discharges naturally reliably, the 200mm place that is above the ground level is provided with manhole waterproof cover 3-3, and cover plate is fixedly mounted on the discharge outlet, can go into maintenance is installed in the underground part by terraced stepping.
