Description

An oil-water diversion device for an accidental oil pool of a power transformer

technical field

The utility model relates to an oil-water diversion device for an accidental oil pool of a power transformer, which belongs to the technical field of electric power equipment.

Background technique

Transformer accident oil pool, as the main structure for transformer oil discharge after transformer failure or fire, plays an important role in effectively avoiding loss expansion and environmental protection. Transformer oil cannot be directly discharged into the sewer network due to fire protection and environmental protection requirements , in the existing technology, the design of the transformer accident oil pool is to design an underground oil storage pool. Every year, the rainwater in the rainy season enters the oil storage pool through the transformer oil pit to the oil storage pool. Often the oil storage pool is full of water, and the work of the substation Personnel need to carry out artificial drainage every time it rains. The workload is huge, which wastes manpower and material resources, which is not conducive to the normal operation of the substation. At the same time, if the water in the pool leaks, it will destroy the bearing capacity of the surrounding foundation soil and make the equipment foundation form badly. Uniform sinking will affect the safe operation of the power grid.

Utility model content

The utility model overcomes the deficiencies of the prior art, and provides an oil-water diversion device with a simple structure, which uses a physical separation method to separate the oil and water for diversion.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a power transformer accident oil pool oil-water separation device, including a transformer, a transformer oil sump and an accident oil sump, the transformer oil sump is arranged below the transformer, and the accident oil sump It is connected with the oil sump of the transformer through a communication pipe, and there is a tee on the communication pipe, and an oil-water separation tank is arranged under the communication pipe. One side of the drainage pipeline is provided with a water collection well, and one end of the drainage pipeline is connected with the oil-water separation tank, and the other end is connected with the water collection well.

The tee includes a vertical pipe and a horizontal pipe, the upper end of the vertical pipe is connected with the oil sump, the lower end is connected with the oil-water separation tank, and the horizontal pipe is connected with the emergency oil pool.

The position where the lower end of the vertical pipe is connected to the horizontal pipe is provided with a funnel-shaped opening

The highest end of the drainage pipe is lower than the lowest end of the communication pipe.

Water is provided in the oil-water separation tank, and the liquid level of the water is located at the intersection of the three links.

Compared with the prior art, the utility model has the following beneficial effects: the use of the oil-water separation pool can achieve a good state of no water in the accident oil pool all year round, cancel the past methods of using water pumps to extract and manually drain water, reduce labor intensity and costs, and pass oil-water The separation tank discharges the water into the water collection well and finally enters the drainage pipe network. It has a simple structure, is economical and efficient, meets the requirements of safety, fire prevention and environmental protection, improves the reliability of the operation of the substation, and avoids the sinking of the equipment foundation caused by the leakage of accumulated water in the pool, etc. Accidents, improve the reliability of substation operation.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described further.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a partially enlarged view of the tee part in Fig. 1 .

In the figure, 1 is the accident oil pool, 2 is the oil-water separation pool, 3 is the water collection well, 4 is the transformer, 5 is the transformer oil collection pit, 6 is the tee, 7 is the inspection well, 8 is the connecting pipe, 9 is the drainage pipe, 10 is the ground, 61 is a vertical pipe, and 62 is a horizontal pipe.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model is a power transformer accident oil pool oil-water separation device, including a transformer 4, a transformer oil sump 5 and an accident oil sump 1, and the transformer oil sump 5 is arranged below the transformer 4, and the accident The oil pool 1 is connected to the transformer oil sump 5 through a communication pipe 8. A tee 6 is arranged on the communication pipe 8, and an oil-water separation pool 2 is arranged below the communication pipe 8. The tee 6 is respectively connected to the oil sump 5, the accident oil pool 1, The oil-water separation pool 2 is connected, and a drainage pipe 9 is arranged below the oil-water separation pool 2. A water collection well 3 is arranged on one side of the drainage pipe 9. One end of the drainage pipe 9 is connected with the oil-water separation pool 2, and the other end is connected with the water collection well 3. The tee 6 includes Vertical pipe 61 and horizontal pipe 62, the upper end of the vertical pipe 61 is connected with the oil sump 5, the lower end is connected with the oil-water separation tank 2, the horizontal pipe 62 is connected with the accident oil pool 1, and the vertical pipe 61 The position where the lower end is connected to the horizontal pipe 62 is provided with a funnel-shaped opening, the highest end of the drainage pipe 9 is lower than the lowest end of the communication pipe 8, and water is provided in the oil-water separation tank 2, and the liquid level of the water is located at the intersection of the tee 6.

When the utility model is in use, a large amount of water is first stored in the oil-water separation tank 2, so that the liquid level of the water is located at the intersection of the tee 6, and the density difference between the oil and the water is utilized, and when the oil-water mixture enters at the same time, the At the position of the tee 6, the oil floats on the upper layer, and the water enters the lower layer. Under the action of gravity, the oil flows to the accident oil pool, and the water is pressed down by the oil and enters the water collection well 3 through the drainage pipe 9. Due to the drainage pipe 9 The highest end is lower than the lowest end of the communication pipe 8, which ensures that the water will not flow back to the oil-water separation tank when the oil-water is divided.

When the separate accumulated water enters through the pipeline, since the drainage pipeline 9 is arranged under the oil-water separation tank 2 and is connected to the water collection well 3, when the water enters, the water will press a part of the water into the water collection well under the action of gravity, so as to keep the water level stable , because the liquid level of the water in the oil-water separation tank 2 is at the intersection of the tee 6, and the intersection is provided with a funnel-shaped opening, so the water will not enter the emergency oil pool from the tee.

The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned embodiments. Make various changes below.
