Oil-immersed transformer with explosion-proof protection structure

Abstract

The invention discloses an oil-immersed transformer with an explosion-proof protection structure, which belongs to the field of oil-immersed transformers, and can realize that when the oil-immersed transformer main body works for a long time and the transformer oil in the oil-immersed transformer main body is in a high-temperature and high-pressure state, the explosion-proof protection structure can be used for protecting the transformer oil in the oil-immersed transformer main body. When the oil-immersed transformer is used, the pressure of the transformer oil is concentrated to the joint between the oil-immersed transformer main body and the anti-explosion protection pot, the movable sealing plug is damaged, and the high-pressure transformer oil is discharged into the protection pot, so that the oil pressure safety in the oil-immersed transformer main body is ensured, the oil-immersed transformer is protected, the high-pressure explosion accident is not easy to occur, and the service life of the oil-immersed transformer is prolonged. The overall transformer is prevented from bursting by controlling the pressure release point of the transformer oil in the oil-immersed transformer at high temperature and high pressure, so that the transformer oil is not easy to splash along with explosion fragments of the transformer, a human body is not easy to be injured, a fire disaster is not easy to be induced, and serious casualties are not easy to be caused.

Description

technical field [0001] The invention relates to the field of oil-immersed transformers, in particular to an oil-immersed transformer with an explosion-proof protection structure. Background technique [0002] Oil-immersed transformer is a transformer that uses petroleum liquid as a sealing and heat-conducting medium. Compared with dry-type transformers, the cost of oil-immersed transformers is low, and due to the protective effect of transformer oil, the heat generated in oil-immersed transformers It is not easy to accumulate, which is convenient for the transformer to dissipate heat. At the same time, its internal coil and other working structures are not easy to be oxidized due to high temperature during the working process, and the cost of use is also much lower than that of dry-type transformers. [0003] However, oil-immersed transformers are generally used in outdoor open areas with fewer people, and dry-type transformers with higher safety performance are generally us...

Problems solved by technology

[0003] However, oil-immersed transformers are generally used in outdoor open areas with fewer people, and dry-type transformers with higher safety performance are generally used in densely populated indoor areas. This is because after long-term high-temperature operation of oil-immersed transformers, The temperature and pressure of the transformer will rise, which will easily cause partial rupture of the oil-immersed transformer. Once the transformer oil, which is flammable and highly polluting, is splashed with the explosion of the transformer, it will easily cause environmental pollution. The transformer is easy to cause irreversible damage to the skin. What's more, once the above-mentioned transformer is ignited, it is easy to induce a large fire and cause serious casualties
