Problems solved by technology

However, such cooling measures are far from meeting the requirements of large-scale transformers. Insufficient cooling of large-scale transformers will cause the copper wires of the transformer to break down and cause the transformer to explode. The consequences are disastrous.

Abstract

The application provides a high cooling type transformer. The high cooling type transformer comprises a transformer main body, a cooling shell, and a pipe; cooling fluid is filled in the cooling shell, and the pipe is in the shape of U; both ends of the pipe are connected with the cooling shell, and the pipe cavity is connected with the inner cavity of the cooling shell; the transformer main body is immersed in the cooling fluid of the cooling shell; the joint between the cooling shell and the transformer main body is provided with a sealing ring. The high cooling type transformer has the beneficial effects of further enhancing the cooling performance, prolonging the work time of the big-power transformer, keeping low temperature rise, cooling for a long time, and avoiding transformer puncture explosion caused by too high temperature.

Description

technical field [0001] This patent relates to the field of transformers, in particular to a highly cooled transformer. Background technique [0002] Transformer cooling technology is a big problem. In the existing technology, the surface area for heat dissipation can be increased by changing the outer wall of the housing and increasing the grooves. On the other hand, by increasing the oil inside the transformer, cooling and insulation are provided. However, such cooling measures are far from meeting the requirements of large-scale transformers. Insufficient cooling of large-scale transformers will cause breakdown of the copper wires of the transformer, resulting in an explosion of the transformer, with disastrous consequences. Contents of the invention [0003] The invention provides a high-cooling transformer. The purpose of the invention is to further enhance the cooling performance, so that the high-power transformer has a long working time and low temperature rise, an...
