Description
The technical field is as follows:
the invention relates to an accident oil pool for a transformer, in particular to an oil-water separation type accident oil pool for a transformer of a 110kV transformer substation.
Background art:
when the main transformer normally operates, heat dissipation needs to be carried out through circulating heat conduction oil; after an accident occurs to the main transformer, since the oil belongs to a flammable medium, in order to avoid causing a fire, the heat conducting oil in the main transformer needs to be discharged to an accident oil pool as accident oil. Meanwhile, after the main transformer has an accident, the main transformer needs to be cooled and put out a fire by using spray water, so that the spray water and the accident oil enter an accident oil pool together; and when the accident oil pool is idle and not used, rainwater can enter the accident oil pool from the gap of the accident oil pool to form accumulated water.
With the release of the design fire standard of a thermal power plant and a transformer substation (GB50229-2019), higher requirements are put on the fire safety and measures of a main transformer, and the oil storage capacity of an accident oil pool of the main transformer is increased to 100% from 60% of the maximum oil quantity of one transformer; therefore, the storage capacity of the accident oil pool, how to efficiently separate oil from water, and how to discharge water are very important.
Traditional accident oil pool is a cylinder oil storage pool, utilizes the density difference of water oil, makes the water oil layering, and then discharges the log raft of lower floor, realizes the effect of water oil separation, however, in the in-service use process, has following problem:
1. because the main transformer discharges oil at a very high speed in the process of discharging the accident oil, the accident oil and water quickly enter the accident oil pool, so that the oil and the water are difficult to form layers, the oil and the water are difficult to be effectively separated, and a part of accident oil is discharged together with the water, thereby not only causing environmental pollution, but also bringing fire hazard;
2. the existing accident oil pool and a water collecting pool for collecting separated water are both arranged independently, and for reconstruction and extension of a transformer substation, main transformer reconstruction (especially capacity-increasing reconstruction) is involved, an accident oil pool needs to be newly built and is limited by a site, the accident oil pool is often far away from the water collecting pool, and after oil and water in the accident oil pool are separated, the separated water cannot be effectively discharged in time, so that the effective volume in the accident oil pool cannot meet the requirement of accident oil storage, and further certain fire safety hazards and poor safety are caused;
3. accumulated water in the accident oil pool occupies the volume of the accident oil pool, and due to the fact that the accumulated water amount in the oil pool cannot be fed back in real time, workers cannot know the accumulated water condition; when an accident oil needs to be discharged, the condition that the effective volume in the accident oil pool cannot meet the accident oil storage requirement can also occur, and the reliability is poor;
