Respirator used for transformer

Abstract

The invention discloses a respirator used for a transformer. The respirator used for the transformer comprises a shell body, wherein the upper end of the shell body is connected with an installation flange, the lower end of the shell body is connected with an oil cup, a ventilating interlayer is arranged between an inner cavity of the oil cup and an inner cavity of the shell body, a gas entrance and exit is arranged at the lower end of the oil cup, allochroic silicagel adsorbent is arranged in the shell body, activated carbon adsorbent is arranged below the allochroic silicagel adsorbent and above the ventilating interlayer to form a double-layer absorption structure, and the shell body is a cylindrical glass container. Due to the fact that the activated carbon adsorbent which is strong-acid-resistance, strong-alkali-resistance, and not easy to break, and can stand water logging, high temperature and high pressure is arranged below the allochroic silicagel adsorbent, in process of working, a capillary tube of a pore structure with highly-developed activated carbon forms a strong adsorption capacity field, and when the capillary tube is touched by gaseous pollutants, the strong adsorption capacity field around activated carbon holes immediately absorbs gas molecules into the holes so as to achieve the effect of gas purifying. The strong adsorption capacity field protects the transformer, simultaneously and effectively prevents toxic substances from leaking, and protects environment.

Description

technical field [0001] The invention relates to a respirator, in particular to a respirator for a transformer. Background technique [0002] The existing respirator suction for transformers includes a housing, a mounting flange is connected to the upper end of the housing, an oil cup is connected to the lower end of the housing, and a breathable barrier is provided between the inner cavity of the oil cup and the inner cavity of the housing. Layer, the lower end of the oil cup is provided with a gas inlet and outlet, and a color-changing silica gel adsorbent is provided in the shell. The adsorbent of the transformer respirator with this structure is a single color-changing silica gel. Although it can absorb moisture in the air and reduce the moisture or oxidation of the transformer oil, which plays a certain role in the safe operation of the transformer, it also has defects as a color-changing silica gel adsorbent. Insufficient, mainly reflected in that some toxic substances...

Problems solved by technology

The adsorbent of the transformer respirator with this structure is a single color-changing silica gel. Although it can absorb moisture in the air and reduce the moisture or oxidation of the transformer oil, which plays a certain role in the safe operation of the transformer, it also has defects and disadvantages as a color-changing silica gel adsorbent. Insufficient, mainly reflected in the production of some toxic substances during use and replacement, which will cause harm to the human body and cause a certain degree of pollution to the surrounding environment
