Description

A cooling device for a transformer

technical field

The utility model relates to the technical field of transformer cooling, in particular to a cooling device for a transformer.

Background technique

In large transformers, transformer oil is usually used to cool the transformer. During the oil cooling process, the transformer oil enters the oil cooling pipe from the inlet of the oil cooling pipe and flows through the oil cooling pipe. During this process, the transformer oil is cooled and the temperature of the transformer oil is lowered. The holes flow back into the transformer to cool the transformer again, and the transformer oil repeats the above operations to cool the transformer.

With the increase of transformer capacity and the impact of environmental changes, the cooling requirements of transformers are getting higher and higher, and the cooling requirements of transformer oil are also getting higher and higher. Simply using the traditional oil cooling method to cool down the transformer oil cannot meet all the requirements. In the prior art, there is a method of installing an air cooler or a water cooler on the oil cooling pipe, but the air cooler cools down in places where the temperature is relatively high Ineffective, water cooler needs to be somewhere with a water source. In addition, primary cooling does not effectively cool the transformer oil.

Utility model content

The purpose of this utility model is to provide a heat dissipation device for a transformer to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions: a cooling device for a transformer, including a motor, the front of the motor is fixedly connected with a base, and the left side of the motor is fixedly connected with the oil pump through a flange, so An oil suction pipe is fixedly installed on the front of the oil pump, an oil distribution pipe is fixedly installed on the lower left side of the oil pump, and a heat dissipation device is fixedly installed on the lower side of the oil distribution pipe. The heat dissipation device includes an oil inlet pipe. The lower part is fixedly connected with a balance pipe, the lower side of the balance pipe is fixedly installed with a cooling fin, the lower part of the cooling fin is fixedly installed with an oil outlet pipe, the lower part of the heat sink is fixedly connected with an oil return pipe, and the right side of the oil return pipe The side is fixedly connected with an oil purifier, and the right side of the oil purifier is fixedly connected with the transformer.

Preferably, the base is fixedly connected to the transformer through screws.

Preferably, at least 8 groups of the cooling devices are arranged, and they are evenly distributed on the lower side of the oil distribution pipe.

Preferably, the heat sink is arranged as an S-shaped hollow sheet.

Compared with the prior art, the beneficial effects of the utility model are: the utility model is simple in structure, convenient and practical, effectively accelerates the cooling of high-heat transformers, makes them cool rapidly, and meets the requirements of some high-performance power transformers. It has the advantages of strong versatility and good cooling effect. By setting the oil pump, the high-heat oil in the transformer can be quickly pumped out, and by setting the oil distribution pipe, the high-heat oil can be evenly distributed to the heat sink. By setting the S-shaped heat sink, the length of the heat sink can be shortened, and the entire device can be reduced. Volume, and expand the area of oil cooling, so that the cooling effect is better.
