Embodiment
The object of this invention is to provide a kind of fully buried steel structure box-type substation, its good reliability, intelligence degree is high and practical.
In order to make those skilled in the art understand technical scheme of the present invention better, describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
Please refer to Fig. 1-4, in one embodiment, fully buried steel structure box-type substation provided by the present invention, comprise cabinet shell 1, cabinet shell 1 is grouped into by lower water section, maintenance part 22 and chest portion, lower water section has the water tank 21 of water leg by bottom and main drainpipe 26 forms, casing part by uncapping greatly 23, ripple tank wall 24 and base 25 form, maintenance part 22 is formed by being arranged on the access hole 13 of uncapping greatly on 23, and water tank 21 and main drainpipe 26 are positioned at ripple tank wall 24 periphery; Transformer 2, low-voltage cabinet 4, slidable stair 6, fire extinguisher 7, high-voltage board 9, divider wall 10, immersible pump 11 is provided with in cabinet shell 1, high-voltage board 9 is connected by high pressure inlet wire cable 8 with outside and connected by high-voltage terminal cable 12 and transformer 2, low-voltage cabinet 4 is connected by low pressure lead-in line row 3 with outside and connected by low-pressure line-outgoing cable 5 and transformer 2, and immersible pump 11 is communicated with main drainpipe 26; The water-proof drainage system of water tank 21, main drainpipe 26 and immersible pump 11 composition; Also comprise ventilating system, temperature control system, anti-condensation system, emergency lighting system, supervisory control system, fire-fighting system and control system, control system controls ventilating system, temperature control system, anti-condensation system, emergency lighting system, supervisory control system, fire-fighting system work.
In such scheme, ripple tank wall 24 makes the structural strength that bellows-shaped mainly increases steel plate, thinner than normally used steel plate, because deflection when contact area will be welded greatly more firmly and weld than whole plate is also much smaller when welding with base 25, uncap greatly and 23 need not make corrugated, because the height of itself is little, it has been the effect of a lid, base 25 not only will bear the weight will bearing components and parts from escheat of casing, and components and parts are all large parts need here in manufacturing process preset many channel-section steels, directly allow the basic one_to_one corresponding of components and parts, whole product also should be lifted by crane by base 25, so the making of base 25 is very solid, the sealing of casing and case lid is as shown in I in figure, use the sealing principle of oil-filled transformer 2, the case of uncap greatly 23 and ripple tank wall 24 is sealed by rubber strip between flange, cause is for convenience of the fastening of bolt and prevent the corrosion of bolt so be placed on box house, but consider to be afraid of that rubber strip overflows due to extruding, specially set up blend stop at rubber strip both sides place, a set of process program being applicable to this product is have employed: all steel plates carry out acid pickling and rust removing process-phosphorating treatment-welding box body-pressure testing anti-drain process-polishing leveling and process-cover oxide-film process-2 road antirust paint process-3 to asphalt caulk spray treatment in order to prevent the corrosion of casing, the thickness of paint film will reach about 0.8mm especially, the product of working it out like this can use for a long time in underground, because the permeability covering asphalt caulk steel plate is not almost just present in, antirust protection against the tide just obtains good process.
The operation principle of such scheme can composition graphs 3: first enter high-voltage board 9 by high pressure inlet wire cable 8, can realize short-circuit protection, high pressure measurement can carry out a distant place/local operation, and high-voltage board 9 adopts totally-enclosed all insulation SF6 gas-filling cabinet, and volume is little, and safety is reliable again; Out directly connect transformer 2 by high-voltage terminal cable 12 from high-voltage terminal cabinet, realize buck functionality by transformer 2; Connect low-voltage cabinet 4 by transformer 2 by low pressure lead-in line row 3 again, main switch adopts intelligent framework circuit breaker simultaneously, and outlet switch adopts breaker of plastic casing band motor-operating mechanism, can carry out a distant place/local operation, and electric capacity adopts local compensation, more convenient; Last low-pressure line-outgoing cable 5 out directly connects electricity consumption feeder pillar from low-pressure line-outgoing cabinet, connects power consumption equipment, thus achieves whole power transformation process; Divider wall 10, can keep apart transformer 2 Room and operating area, does not have the special key of special messenger not open isolating door, can realize not needing power-off just can enter casing and carry out service work.
Water-proof drainage system shell composition graphs 1 and Fig. 4, the major function of water tank 21 is used as to ventilate instead of be used for being filled with water, and water tank 21 maintains an equal level with ground afterwards with whole casing is pre-buried, so the water of water tank 21 mainly comes from rainwater, again because water tank 21 is an independent entirety, so rainwater can not flow through box house, directly by water tank 21 drainage pipe in Fig. 4, water is discharged to municipal drainage pipeline 14, as run into catastrophic flood damage, whole product is all flooded, at this moment in Fig. 5, the first electric butterfly valve 33 and the second electric butterfly valve 36 just serve a key effect, it can receive the Automatic shutting-down of signal ventilating opening of fluid level controller in water tank 21, whole casing is made to form an airtight space, serve the effect of waterproof, simultaneously, in the design of casing, there is a Stilt layer location of components and parts and casing, at this moment the 2nd defence line, road of draining is just defined with immersible pump in Fig. 3 11 drainage system, after intaking inside infiltration or defective valve casing as run into, water can flow in Stilt layer, at this moment the immersible pump 11 in Stilt layer will receive the enabled instruction of fluid level controller in casing, carries out draining, water is drained into water tank 21 drainage pipe and finally flows in municipal drainage pipeline 14.
The Main Function of exhaust system is the air-flow exchange inside and outside casing, is alternatively the heat radiation in casing.Generally first, second electric butterfly valve 36 is be in a state of opening for a long time, and both sides form the pattern of an one-in-and-one-out.Wind comes in enter casing through intake stack 35 from air inlet 37 as can be seen from Figure 5, is exported by hot blast, define exchange heat effect after exchange heat by axial flow blower 34 by wind pipe 32 air outlet 31.
In sum, compared with prior art, complete machine all imbeds underground to the technical scheme disclosed by the present embodiment, ground can be afforested, beautify and maybe can do road, parking lot, greatly save land used, saves capital expenditure; Have water-proof drainage system, ventilating system, temperature control system, anti-condensation system, emergency lighting system, supervisory control system, fire-fighting system and control system, intelligence degree is high; Full-shield constructs, and without magnetic field radiation, the equipment such as transformer 2 and high-low pressure cabinet 4 are inserted in complete buried casing and imbedded underground, ensures ground noiselessness interference, good reliability.
