Problems solved by technology
[0003] The purpose of the present invention is to solve the existing transformer accident oil storage pool. When an accident occurs in the transformer and the oil needs to be drained, the current design method must be used for calculation every time, which brings inconvenience to the engineering design. When the oil needs to be drained, the accumulated water in the emergency oil storage tank will not be discharged, and it is easy to cause freezing damage in winter, destroy the impermeability of the accident oil pool, and cause technical problems of environmental pollution. A kind of oil-water separation for the transformer accident oil storage tank is provided. device

specific Embodiment approach 1
[0011] Specific implementation mode one: combine figure 1 , the oil-water separation device of a kind of transformer emergency oil storage tank of the present embodiment is made up of oil inlet pipe 1, three-way butterfly valve 2, oil discharge pipe 3 and drain pipe 4; The outlets are connected, one outlet of the three-way butterfly valve 2 is connected to the inlet of the oil discharge pipe 3, and the other outlet of the three-way butterfly valve 2 is connected to the inlet of the drain pipe 4.
[0012] Beneficial effects of this embodiment
[0013] The oil-water separation device of the transformer accident oil storage tank of the present invention can completely separate the oil and water in the transformer accident oil storage tank in a non-sealed state, save space for oil discharge, and eliminate potential safety hazards of equipment; it can prevent the water in the accident oil storage tank from In winter, frost heave damage is caused, the wall of the oil pool is swelle...

The invention relates to an oil-water separating device for a transformer accident oil reservoir, and relates to an oil-water separating device. The oil-water separating device aims to solve the technical problems of an existing transformer accident oil reservoir that calculation is needed every time that an existing design method is adopted as long as a transformer accident occurs to need oil drainage so as to cause inconvenience for engineering design, accumulated water in the accident oil reservoir cannot be drained when no accidents occur or oil drainage is not needed, and the anti-penetrability performance of the accident oil reservoir is damaged by freeze injury occurring easily in winter so as to cause environmental pollution. The oil-water separating device for the transformer accident oil reservoir disclosed by the invention consists of an oil inlet tube, a three-way butterfly valve, an oil drainage tube and a water drainage tube; an inlet of the three-way butterfly valve is connected with an outlet of the oil inlet tube; one outlet of the three-way butterfly valve is communicated with an inlet of the oil drainage tube, and the other outlet of the three-way butterfly valve is communicated with an inlet of the water drainage tube. The oil-water separating device is applied to transformer substation accident oil reservoirs with the voltage of 110kV or more.
Description
technical field [0001] The invention relates to an oil-water separation device. Background technique [0002] The current 110kV substation adopts the A-3 typical design module of the State Grid. The structure adopted is that there is an oil inlet pipe at the bottom of the transformer oil pool connected to the emergency oil storage pool. oil storage tank. When the transformer needs to discharge oil due to an accident, if there is no water in the oil storage tank, it will directly play the role of oil storage; if there is water in the oil storage tank, because the oil is lighter than water, the oil floats above the water surface, and the oil continues to flow into the oil storage tank. When the oil level is higher than the horizontal position of the drain pipe, the oil will use its own gravity to press the water out of the emergency oil storage tank through the drain pipe to achieve the purpose of oil-water separation. In order to fully realize the above oil-water separation...
