Problems solved by technology

[0003] Power transformers will generate a lot of heat during use. If they are not dissipated, the service life of the transformer and the safety of use will be seriously reduced. Moreover, the existing commonly used oil-immersed transformers, the transformer oil in them will be used for a long time Finally, impurities will be formed, which will affect the use. Therefore, it is necessary to filter the transformer oil to prolong the service life of the transformer oil

Abstract

The invention discloses a power transformer for a power distribution network substation. The power transformer comprises a transformer body, wherein a high-voltage bushing and a low-voltage bushing are arranged at the top of the transformer body, two fixing frames are fixedly connected to the side wall, close to the top, of the transformer body, and the tops of the two fixing frames are connected with the same oil conservator; a first connecting pipe is connected between the oil conservator and the transformer body, a gas relay is arranged on the first connecting pipe, a fourth connecting pipe is arranged at the top of the oil conservator, a rubber bag is connected to the end, located in the oil conservator, of the fourth connecting pipe, and a second connecting pipe is connected to the end, located outside the oil conservator, of the fourth connecting pipe; the other end of the second connecting pipe is connected with a moisture absorber, and a cooling mechanism is connected between the two fixing frames. The power transformer is advantaged in that good and efficient cooling and heat dissipation can be achieved, meanwhile, filtering and impurity removal can be conducted on transformer oil, the service life of the transformer oil is prolonged, and stable operation of a transformer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a power transformer used in distribution network substations. Background technique [0002] The distribution network substation is an important part of the system of power generation, transmission, transformation, power distribution and power consumption. The power transformer is a static electrical device used to transform AC voltage and current to transmit AC power. [0003] Power transformers will generate a lot of heat during use. If they are not dissipated, the service life of the transformer and the safety of use will be seriously reduced. Moreover, the existing commonly used oil-immersed transformers, the transformer oil in them will be used for a long time Finally, impurities will be formed, which will affect the use. Therefore, it is necessary to filter the transformer oil to prolong the service life of the transformer oil. Contents of the invention [0004...
