During an accident, the accident oil pool not only receives the transformer oil, but also receives the water used for fire extinguishing. The accident oil pool is also an oil-water separation device. At present, most of the accident oil pools are buried oil separation pools. After passing through the oil separation pool, the oil and water are separated due to the different densities, and the transformer oil is placed on the upper layer of the accident oil pool.

In this way, the water pump discharging method will discharge the oil and water together, which not only reduces the oil-water separation function of the accident oil pool, but also increases the water volume and load for the later recovery of the transformer oil. At the same time, the accident oil pool needs to have a certain amount of water to play a water seal role. After the submersible pump empties the accident oil pool, the water seal water needs to be supplemented, which causes water waste. SUMMARY
