Description
Technical field
This utility model relates to water separation tank, particularly relates to a kind of buried electric substation transformer oil water separating tank.
Background technology
4.1.3 regulation indoor substation every oil mass according to " 20KV and following substations ' design specification " GB50053 is big
In the transformator equal to 100kg, should be arranged in single transformer room, and should have the fire prevention measure such as oil storage or gear oil, oil extraction.
The 5.5.2 of " 3kV～115kV high voltage distribution installation " GB50060 specifies that the oil mass of separate unit electrical equipment within doors is at more than 100kg
Time, oil storage facility or gear oil facility should be set.The volume of gear oil facility by accommodating 20% oil mass design, and should should have accident oil
Drain into the facility of safe place；When not meeting above-mentioned requirements, the oil storage facility that can accommodate 100% oil mass should be set." firepower is sent out
Power plant and Substation Design fire safety rules " 11.2.2 of GB50229 specifies that the transformator of underground substation should be arranged and can store
The emergency oil reservoir of a big transformator oil mass.
Because being installed on underground, there is the potential safety hazard of water inlet, being equipped with drainage system in buried electric substation.Such as transformator
Oil leakage fault occurs, and accident oil is directly discharged into drainage system, can cause environmental pollution, builds if entering other by drainage system
Building thing, other buildings are produced fire disaster hidden danger, these are all not permitted in national legislation.
Because buried electric substation transformator oil mass is less, the restriction of the limited grade of the underground space, emergency oil pond should not be set,
The oil storage pool of receiving 100% transformator oil mass is generally provided below at transformator.But when the oil storage pool of transformator has stored up because intaking
During full water, now Accident of Transformer leakage of oil, accident oil still can overflow from oil storage pool, and oil storage pool loses oil storage function.
Utility model content
The purpose of this utility model is to provide one to ensure that hydrops all can normally be automatically drained out in any case, thing
Therefore the one buried electric substation transformer oil water separating tank that oil can all be stored in oil storage pool.
This utility model includes the oil storage pool being placed in below transformator, sets overflow pipe, overflow pipe one end in described oil storage pool
Being placed in oil storage pool bottom, the other end is placed in oil storage pool top, is connected with the drainage system outside oil storage pool.
Setting water separation tank in this utility model oil storage pool, water separation tank comprises at least one bin, is all provided with in bin
Overflow pipe, overflow pipe one end is placed in bin bottom, and the overflow pipe other end connects through bin top with next stage bin or drain pipe
Connect, be positioned at bin bottom foremost and be provided with liquid-inlet.
It is provided with drainage screen at described liquid-inlet.
In this utility model oil storage pool after oil mixing with water, because the density of profit is different and the two mutual exclusive characteristic, lead
Causing the two Bedding storage in oil storage pool, oil is on upper strata, and lower layer of water, in lower floor, is arranged by water by the overflow pipe in water separation tank
Go out, oil is stayed in oil storage pool, it is to avoid accident oil is directly entered drainage system.

Detailed description of the invention
Being provided with transformer foundation 3, water separation tank 1 in this utility model oil storage pool 2, case is installed at water separation tank 1 top
Top movable steel cover plate 4, inside is separated into two storehouses by steel plate, and i.e. water storage 5, surge bunker 6, set liquid-inlet bottom water storage 5,
Set at liquid-inlet filtration silk screen 8, water storage 5, surge bunker 6 are all provided with an overflow pipe 7, overflow pipe 7 water inlet bottom storehouse,
Discharge outlet on the top in storehouse and is connected with drainage system.Refer to Fig. 1-Fig. 2.
Operation principle: this water separation tank operation principle, is to utilize after oil mixing with water because the density of profit is different and the two
Mutual exclusive characteristic, causes the two Bedding storage in oil storage pool 2, and oil is on upper strata, and water is in lower floor.By this device, water is arranged
Go out, oil is stayed in oil storage pool 2.This utility model oil storage pool effectively stores volume and should be greater than the volume of transformator all oil.Become
Depressor basis 3 should be higher than that absolute altitude at the bottom of overflow pipe 7 discharge outlet, prevents transformator from soaking.
This water separation tank 1 lands installation in oil storage pool 2, and height is the most contour with oil storage pool 2.The overflow of surge bunker 6
Pipe 7, through oil storage pool wall, accesses drainage system.The filtration silk screen 8 of water storage 5 bottom inlet, is possible to prevent foreign material to block overflow
Pipe.This utility model overflow pipe 7 ensure that the overflow of oil storage pool 2 bottom liquid elder generation is discharged.Case top movable steel cover plate 4, first can be every
Air absolutely, prevents a small amount of accident oil from burning in case, has fire-extinguishing function concurrently；Next prevents foreign material from entering in storehouse, case top movable steel
Cover plate 4 also facilitates cleaning and the maintenance of water separation tank 1.It is divided into two storehouses and mainly considers oil water mixture secondary separation, it is ensured that
Drain is essentially water.
Utility model works process:
1) when transformer room's oil storage pool 2 is intake, when the water surface is higher than overflow pipe 7, water enters bottom overflow pipe 7, from
It is automatically drained out from overflow pipe 7 discharge outlet, enters drainage system, do not affect transformator properly functioning.
2) when the oil storage pool 2 of transformator is anhydrous, transformer fault leakage of oil, now the dischargeable capacity of oil storage pool 2 is more than becoming
The volume of depressor oil, transformer oil surface height does not reaches overflow pipe 7 height, and transformer oil storage 2, in oil storage pool, will not enter
Drainage system.
3) when having had water in the oil storage pool 2 of transformator, transformer fault leakage of oil, now the two divides in oil storage pool 2
Layer storage, oil is on upper strata, and water is in lower floor.Oil water mixture enters water storage, carries out oil-water separation, and carry out mud in water storage
The sealing-off fire of husky precipitation and case top movable steel cover plate 4 processes, when liquid level is higher than overflow pipe 7 discharge outlet, water storage 5 lower floor
Water first passes through overflow pipe 7 and enters surge bunker 6；An oil-water separation, sediment deposition and case top is carried out again movable in surge bunker 6
The sealing-off fire of steel deck-plate 4 processes, and now in surge bunker 6, the water of the not oil-containing of lower floor enters drainage system by overflow pipe 7.By
Constantly it is discharged in oil storage pool 2 bottom water, it is ensured that the capacity of oil storage pool 2 can meet the storage of whole transformer oil.
This utility model is simple small and exquisite can be met transformer oil storage pond and install, and reliability is high, cheap, because of it the most not
Change transformer oil storage pool structure, be also very suitable for the oil-water separation transformation of operating transformer oil storage pool.
Description above only shows and describes this utility model ultimate principle, principal character and advantage thereof, without departing from this
On the premise of utility model spirit and scope, this utility model also has various changes and modifications, includes but not limited to such as size
The measures such as change, employing concrete storehouse, increase and decrease bin, all both fall within the range of claimed this utility model.This practicality
Novel claimed scope is defined by appending claims and equivalent thereof.
