Transformer respirator

Abstract

The invention provides a transformer respirator. The transformer respirator comprises a silica gel cylinder for storing silica gel particles, an upper cover arranged on the upper side of the silica gel cylinder, a breathing disc arranged on the lower side of the silica gel cylinder, an inner oil cup and an outer oil cup, wherein the inner oil cup and the outer oil cup are arranged on the lower side of the breathing disc and used for storing transformer oil; the transformer respirator is characterized by also comprising an extending oil cup fixed on the upper side of the breathing disc and communicated with the inner oil cup and a separation net arranged on the upper side of the extending oil cup and used for bearing the silica gel particles, the separation net is arranged inside the silicagel cylinder, the separation net and the extending oil cup are arranged at an interval, and the area of the cross section of the extending oil cup is larger than the area of the cross section of theinner oil cup. According to the transformer respirator, the problem that silica gel in an existing respirator is contaminated by splashed transformer oil is solved; the flowing space of the transformer oil is increased, and the silica gel contamination problem caused by rapid rising of the transformer oil level caused when the temperature of a transformer changes is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of transformers, and more specifically relates to a transformer respirator. Background technique [0002] The transformer oil storage respirator is an important safety protection device for power transmission equipment. The respirator is installed at the end of the pipeline connecting the transformer oil storage tank with the air. When the temperature of the transformer oil rises, the oil level of the oil conservator will rise correspondingly, so that the gas in the capsule will be discharged through the respirator; on the contrary, when the temperature of the transformer drops, the oil level of the oil conservator will also decrease accordingly, and the capsule will be inhaled through the respirator part gas. However, if the temperature of the transformer oil changes sharply and the transformer oil level in the oil cup rises rapidly, there will be a hidden danger that the transformer oil will splash onto t...
