Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer oil tank with a shock-absorbing function. Background Art

[0002] With the development of society, the use of electricity is becoming more and more widespread, and the transmission of electricity requires the use of transformers. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. They are mainly composed of iron cores, windings, oil tanks and other components. During the operation of the transformer, the iron core and windings will generate a lot of heat, which needs to be dissipated through transformer oil. Therefore, the temperature of the transformer oil is crucial to the normal operation of the transformer.

[0003] At present, the existing transformer oil tank usually does not have a pre-cooling function, which causes the temperature of the transformer oil entering the oil tank to be high and the working pressure of the oil tank to be large, which affects the heat dissipation effect of the transformer. In addition, during the operation of the transformer, due to the increase in oil temperature, the cooling oil will expand, thereby increasing the internal pressure of the oil tank. If the sealing performance of the oil tank is not good, the cooling oil will leak, which will not only affect the normal operation of the transformer, but also cause pollution to the environment. The existing transformer oil tank lacks effective leakage detection means. Once a leak occurs, it is difficult to detect and deal with it in time, which easily leads to safety accidents.

[0004] Therefore, it is necessary to provide a transformer oil tank with a shock absorbing function to solve the above technical problems. Utility Model Content

When the transformer oil tank leaks due to thermal expansion and contraction, the transformer oil will flow into the oil leakage guide groove 14 and then into the alarm 15. After the transformer oil enters the conical guide groove 16, the two sensor blocks 19 sense that the transformer oil has passed through, and send a warning message to the staff through the controller 18 to remind the staff to perform maintenance. The collecting bin 20 can collect the leaked refrigerant oil.

[0022] A shock absorbing plate 21 is fixedly connected to the bottom of the pre-cooling rack 2, and a shock absorbing layer 22 is arranged on the top surface of the shock absorbing plate 21. The shock absorbing layer 22 is made of rubber. When the oil tank 1 vibrates, the rubber of the shock absorbing layer 22 can effectively absorb vibration energy and perform shock reduction.
