Explosion-proof oil-immersed transformer

Abstract

The invention discloses an explosion-proof oil-immersed transformer which comprises an oil-immersed transformer shell, an oil conservator fixed on the oil-immersed transformer shell, and an explosion-proof oil tank fixed on the oil-immersed transformer shell, the oil conservator is communicated with the oil-immersed transformer shell through an oil inlet pipe and an oil outlet pipe; each of the oil inlet pipe and the oil outlet pipe is connected with a one-way valve; the oil inlet pipe is connected with a filter assembly in series, and the shell of the oil-immersed transformer is fixedly connected with a buffer device. The oil conservator is matched with the shell of the oil-immersed transformer, so that the phenomenon of burnout of the tap switch caused by exposure of the tap switch due to oil level drop is reduced. The filtering assembly is used for filtering impurities and sediments, so that the service life is prolonged. The buffer device reduces rigid impact generated by working vibration of the oil-immersed transformer and reduces the phenomenon that the oil-immersed transformer is damaged.

Description

technical field [0001] The invention relates to a transformer, in particular to an explosion-proof oil-immersed transformer. Background technique [0002] The oil-immersed transformer is usually a fully enclosed box. When the product encounters heat or load, it will expand when it heats up or shrink when the box expands, causing the oil level in the box to drop. The tap changer is exposed to the outside of the oil, resulting in decomposition. Burnout of the switch. [0003] At the same time, after the oil-immersed transformer has been used for a long time, impurities and sediments will appear in the internal oil, which will affect the service life of the transformer. [0004] In the prior art, the oil-immersed transformers are directly fixedly connected. When local vibration occurs outside or the working vibration of the oil-immersed transformer causes a rigid shock to the oil-immersed transformer, the oil-immersed transformer will be damaged after a long time.

[0003] At the same time, after the oil-immersed transformer has been used for a long time, impurities and sediments will appear in the internal oil, which will affect the service life of the transformer.

[0004] In the prior art, the oil-immersed transformers are directly fixedly connected. When there is a local vibration in the outside world or the working vibration of the oil-immersed transformer, the oil-immersed transformer will have a rigid impact, and the oil-immersed transformer will be damaged after a long time.
