respirator for transformer

Abstract

The invention provides a respirator for a transformer, which belongs to the technical field of transformers, and includes a casing, an electric heating element, an electric valve and a controller; wherein, the inside of the casing is used for filling desiccant; The oil conservator is connected, and the bottom wall is provided with a breathing channel for connecting the inside of the transformer oil conservator, the inside of the housing and the outside world; the top wall of the housing is provided with an air intake channel and an exhaust channel respectively used to communicate with the outside world; the electric heating element It is installed inside the shell and is used to heat the desiccant; the electric valve is set on the top wall of the shell, which has the first state of closing the intake passage and opening the exhaust passage, and also has the second state of opening the intake passage and closing the exhaust passage Two states: the controller is set on the outer wall of the casing, and is electrically connected to the electric heating element and the electric valve respectively. The respirator for a transformer provided by the invention can quickly restore its water absorption performance by heating and dehumidifying when the desiccant fails, without disassembling the shell to replace the desiccant, reducing the waste of manpower and materials.

Description

technical field [0001] The invention belongs to the technical field of transformers, and more specifically relates to a respirator for transformers. Background technique [0002] The respirator is a safety protection device installed at the end of the pipeline where the oil conservator of the transformer communicates with the air. When the oil temperature inside the transformer rises and expands, the excess air inside the transformer will be exhaled, and when the oil temperature of the transformer decreases and shrinks, it will be inhaled from the outside. Air, and when inhaling outside air, in order to prevent the oil inside the transformer from being damp and deteriorated, it is necessary to absorb the moisture in the air through the silica gel in the respirator, so as to ensure that the air inhaled by the transformer is dry air. [0003] The main component of silica gel is activated alumina, which belongs to a desiccant. In the normal dry state, the color of silica gel is...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a respirator for transformers, which aims to solve the problem that the silica gel in the existing respirator needs to be replaced after it becomes damp and fails, which affects the normal operation of the transformer and causes waste of manpower and material resources.
