Abstract
The utility model relates to a 66kV transformer substation oil-water separation type transformer accident oil storage pond. The 66kV transformer substation oil-water separation type transformer accident oil storage pond is characterized in that a separation part is arranged in the oil storage pond to enable the oil storage pond to be divided into an oil pond body and a water pond body, a water discharging pipe and a water discharging gate valve are installed between the oil pond body and the water pond body, and the oil pond body and the water pond body are connected with an oil inlet pipe and a water outlet pipe respectively. According to the 66kV transformer substation oil-water separation type transformer accident oil storage pond, the good water-free condition can be achieved throughout the year, the water pump pumping and manual water discharging methods in the past are removed, labor intensity and cost are reduced, water is conveniently discharged, the accident oil storage pond is free of water in winter, and therefore the accident oil storage pond is prevented from being damaged by frost heaving of water. Oil-water separation meets the safety fire protection and environment-friendly requirements, the economic benefits are large, 30000 yuan can be saved each year, the operating reliability of a transformer substation is improved, and reliable guarantees are provided for local industrial and agricultural production power utilization and people live power utilization.
Description
Technical field
The utility model relates to a kind of power equipment oil storage pool, relates in particular to a kind of 66kV transformer station water-oil separating formula Accident of Transformer oil storage pool.
Technical background
The newly-built 66kV transformer station with enlarging is many in recent years, complete no matter be indoor substation, or half indoor substation.All relate to Accident of Transformer oil extraction problem.The Accident of Transformer oil extraction is because the requirement of fire-fighting and environmental protection can not directly enter in the sewer pipe net.In prior art, the oil extraction of Design of Transformer accident, be that one of design has into the oil storage pool without going out.Every year, rainy season, rainwater entered oil storage pool by transformer oil pit to oil storage pool connecting leg.Often oil storage pool water is very full.In order to guarantee the Accident of Transformer oil extraction, the staff of transformer station needs to carry out the pump drainage of oil storage pool water and artificial drainage after each raining.Workload is very large, and the wasting manpower and material resources is unfavorable for that transformer station normally moves.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, by the investigation to the Accident of Transformer oil storage pool for many years, it is improved, provide a kind of can draining again can oil storage 66kV transformer station water-oil separating formula Accident of Transformer oil storage pool, solved in prior art oil storage pool drainage works amount large, the wasting manpower and material resources, be unfavorable for the normal problem of moving of transformer station.
Technical solutions of the utility model are as follows:
Barrier is set in oil storage pool and is divided into oil sump and pond, fix a drainpipe and drainage valve between oil sump and pond, oil sump is connected respectively oil inlet pipe and outlet pipe with pond.
Described sump volume and transformer oil heavy phase coupling.
Described sump volume is greater than pool volume.
Described gutter bottom nozzle is apart from 100mm at the bottom of pond.
Described gutter top is higher than oil storage oil level line.
Described drainage valve switch is located in pond.
Described oil inlet pipe is located at the below of freezing layer.
The utility model compared with prior art, has following effect:
1, adopt the water-oil separating oil storage pool can reach the long-term anhydrous kilter of oil storage pool, cancel the method for past with water pump extraction and artificial drainage, reduce labour intensity and expense, and, because draining facilitates the winter oil sump anhydrous, eliminate because water frost heave damage accident oil storage pool is arranged.
2, water-oil separating meets fire safety and environmental requirement, and economic benefit is far-reaching, can save 3.0 ten thousand yuan of funds every year.
3, improve the substation operation reliability, for local industrial and agricultural production and people's lives electricity consumption provide reliable guarantee, promoted local economic development, showed the favorable image of power supply enterprise.

In figure, 1, oil sump, 2, pond, 3, barrier, 4, gutter, 5, drainage valve, 6, oil inlet pipe, 7, outlet pipe, 8, enter hole, 9, the oil level line, 10, freeze layer.
The specific embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, the utility model is elaborated as follows.
Embodiment
As Figure 1-3, barrier 3 is set in oil storage pool and is divided into oil sump 1 and pond 2, sump volume and transformer oil heavy phase coupling; Sump volume is greater than pool volume; Fix a drainpipe 4 and drainage valve 5 between oil sump and pond, gutter 4 bottom nozzles are apart from 100mm at the bottom of pond, and gutter 4 tops are higher than oil storage oil level line 9; Drainage valve 5 switches are located in pond 2; Oil sump is connected respectively oil inlet pipe 6 and outlet pipe 7 with pond, and oil inlet pipe 6 is located at the below of freezing layer 10.The top in oil sump and pond is respectively equipped with and enters hole 8.
The course of work of the present utility model and principle are as follows:
Due to rainy oil sump water, when the Accident of Transformer oil extraction, when oil flows to oil sump by oil inlet pipe, according to the difference of profit proportion, transformer oil density 0.85T/m3, water density 1.00T/m3, oil upper water under, along with the increase of the weight that enters oil sump oil, in oil sump water by the distance pond at the bottom of the high gutter bottom nozzle of 100mm enter a wall in washing basin, and enter drainage network by outlet pipe, and oil exists in oil sump.
When rainy oil sump water, open the drainage valve draining after rain, and enter drainage network by outlet pipe.
The utility model is tested in XX66kV transformer station capacity-increasing transformation engineering, respond well.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on the technical solutions of the utility model basis, within all belonging to protection domain of the present utility model.
