Anti-backflow structure of transformer respirator

Abstract

The invention belongs to the technical field of transformer matching structures or equipment, and particularly relates to an anti-backflow structure of a transformer respirator. The anti-backflow structure comprises: an oil collecting cylinder, wherein air inlet channel and an air outlet channel are respectively formed in the top and the bottom of the oil collecting cylinder; an air inlet pipe which is arranged in the air inlet channel, an air outlet hopper which is arranged in the air outlet channel, an air inlet hopper which is arranged at the lower end of the air inlet pipe, and a shade which is buckled above the air outlet hopper. The anti-backflow structure of the transformer respirator is mainly used between breathing pipelines of various oil-immersed structures such as the respirator of an oil-immersed transformer and connecting pipelines of other spaces and used for eliminating and filtering transformer oil and the like with shoe polish, moisture and other gas impurities generated in a high-temperature working environment, the performance of the oil-immersed structure can be improved. The anti-backflow structure comprises devices including transformer and the like.

Description

technical field [0001] The invention belongs to the technical field of transformer supporting structures or equipment, and in particular relates to an anti-backflow structure of a transformer respirator. Background technique [0002] The oil-immersed structure or equipment has good heat dissipation, anti-interference / lightning and impact characteristics, and at the same time has low cost and good insulation, so it is widely used in various high-voltage requirements of the power grid, and then derived oil-immersed transformers, and All kinds of oil-immersed heat dissipation and protection structures, but everything has advantages and disadvantages. Although oil-immersed transformers have many advantages, due to the use of a large amount of transformer oil, it is inevitable to be restricted by transformer oil and corresponding structural design.

Problems solved by technology

[0002] The oil-immersed structure or equipment has good heat dissipation, anti-interference / lightning and impact characteristics, and at the same time has low cost and good insulation, so it is widely used in various high-voltage requirements of the power grid, and then derived oil-immersed transformers, and All kinds of oil-immersed heat dissipation and protection structures, but everything has advantages and disadvantages. Although oil-immersed transformers have many advantages, due to the use of a large amount of transformer oil, it is inevitable to be restricted by transformer oil and corresponding structural design. And produce corresponding defects, the most common of which is that due to the flammability and fluidity of transformer oil, it is flammable and explosive, and transformer oil is easy to invade other structures. The penetration and sealing structure can better solve the problems of transformer oil leakage, but in the long-term use process, because the transformer oil and the transformer itself work at high temperature for a long time, under the influence of various factors such as evaporation and splashing, it is difficult to connect the transformer Oil and the pipelines and spaces of various components are inevitably mixed with transformer oil vapor with high or low concentration. Although the single content is not high, impregnation and oil droplets will still form in specific areas after long-term use. At the same time There is a small amount of moisture in the steam, which will easily bring hidden dangers to the normal operation of the oil-immersed structure after long-term accumulation, and affect the performance of transformers and other equipment
