Abstract
The invention relates to an oil-water separation type emergency oil storage pool for a transformer of a 66kV substation. The oil-water separation type emergency oil storage pool is structurally characterized in that a baffle is arranged in the oil storage pool to divide the oil storage pool into an oil pool and a water pool, a water drain pipe and a water drain gate valve are installed between the oil pool and the water pool, and the oil pool and the water pool are respectively connected with an oil inlet pipe and a water outlet pipe. By adopting the oil-water separation type emergency oil storage pool, a good condition that the oil storage pool does not contain water throughout the year can be reached, the traditional methods of pumping the water by using a water pump and manually draining the water are abandoned and the labor intensity and the labor cost are reduced; and since the water is convenient to drain and the oil storage pool does not contain water in winter, the situation that the emergency oil storage pool is damaged due to water frost heaving is eliminated. Oil-water separation complies with requirements on safety, fire prevention and environmental protection, the economic benefit is great and thirty thousand Yuan can be saved every year. The operation reliability of the substation is improved and a reliable guarantee is provided for local industrial and agricultural production and household electricity use of people.
Description
Technical field
The present invention relates to a kind of power equipment oil storage pool, relate in particular to a kind of 66kV transformer station water-oil separating formula Accident of Transformer oil storage pool.
Technical background
66kV transformer station newly-built and 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 owing to the requirement of fire-fighting and environmental protection can not directly enter in the sewer pipe net.In the prior art, the oil extraction of Design of Transformer accident is that one of design has into without the oil storage pool that goes 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 the raining.Workload is very large, and the wasting manpower and material resources is unfavorable for that transformer station normally moves.
Summary of the invention
The present invention is directed to 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, it is large to have solved in the prior art oil storage pool drainage works amount, the wasting manpower and material resources is unfavorable for the normal problem of moving of transformer station.
Technical solution of the present invention is as follows:
Barrier is set in the oil storage pool is divided into oil sump and pond, fix a drainpipe and drainage valve between oil sump and the pond, oil sump and pond connect respectively oil inlet pipe and outlet pipe.
Described sump volume and transformer oil heavy phase coupling.
Described sump volume is greater than pool volume.
Described gutter bottom nozzle 100mm at the bottom of the pond.
Described gutter top is higher than oil storage oil level line.
Described drainage valve switch is located in the pond.
Described oil inlet pipe is located at the below of freezing layer.
The present invention 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, the cancellation past is extracted with water pump and the method for artificial drainage, reduce labour intensity and expense, and because draining makes things convenient for 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.

Fig. 3 is section II structural representation of the present invention.
Among the figure, 1, oil sump, 2, the pond, 3, barrier, 4, gutter, 5, drainage valve, 6, oil inlet pipe, 7, outlet pipe, 8, enter the hole, 9, the oil level line, 10, freeze layer.
The specific embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, it is as follows that the present invention is described in detail.
Embodiment
As Figure 1-3, barrier 3 is set in the oil storage pool 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 the pond, gutter 4 bottom nozzles 100mm at the bottom of the pond, gutter 4 tops are higher than oil storage oil level line 9; Drainage valve 5 switches are located in the pond 2; Oil sump and pond respectively connect oil inlet pipe 6 and outlet pipe 7, 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 invention and principle are as follows:
The oil sump water owing to rain, 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 at upper water lower, along with the increase of the weight that enters oil sump oil, in the 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 the oil sump.
When rainy oil sump water, open the drainage valve draining behind the rain, and enter drainage network by outlet pipe.
The present invention tests in XX66kV transformer station capacity-increasing transformation engineering, and is respond well.
The above is specific embodiments of the invention and the know-why used, and is any based on the equivalent transformation on the technical solution of the present invention basis, all belongs within protection scope of the present invention.
