Abstract

The invention discloses a transformer breather and belongs to the technical field of power equipment. Th transformer breather comprises a dryer, transformer breathing structures and a two-position four-way reversing valve which are sequentially connected and communicated with one another; the transformer breather further comprises an oil conservator connecting pipe and an air connecting pipe which are arranged on the two-position four-way reversing valve; the number of the transformer breathing structures is two; the transformer breathing structures are the first transformer breathing structure and the second transformer breathing structure which are the same in structure; the first transformer breathing structure is communicated with the conservator connecting pipe through the two-position four-way reversing valve, the dryer is communicated with the air connecting pipe through the second transformer breathing structure and the two-position four-way reversing valve, or the second transformer breathing structure is communicated with the conservator connecting pipe through the two-position four-way reversing valve; and the dryer is communicated with the air connecting pipe through the first transformer breathing structure and the two-position four-way reversing valve. Through the dryer, the transformer breathing structures, the two-position four-way reversing valve, the oil conservator connecting pipe, the air connecting pipe and the like, insulating oil of a transformer is not prone to being affected with damp or oxidized.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a transformer respirator. Background technique [0002] The transformer breather is an intermediate device connecting the transformer insulating oil with the outside air, the purpose is to filter out impurities and moisture in the air. In a humid environment, due to the large amount of moisture, the color-changing silica gel in the drying room of the transformer respirator is easy to change color. Once it is not found in time, too much moisture will enter the inside of the transformer, which will easily cause the insulating oil of the transformer to be damp and oxidized. affect the stable operation of the transformer. Frequent replacement of the respirator will also allow excessive moisture to enter the interior of the transformer when the respirator is disassembled. [0003] Existing technical problems and thinking: [0004] How to solve the technical problem that ...
