Capsule, transformer oil conservator, gas leakage detection method and device

Abstract

The embodiment of the present application provides a capsule, a transformer oil conservator, and a gas leakage detection method and device. The capsule includes: an elastic capsule bag and an air guiding component for being arranged in the transformer oil conservator; the inner cavity of the elastic capsule bag The through hole provided on the top of the transformer oil conservator communicates with the outside of the transformer oil conservator, and a sealed oil chamber is formed between the outer wall of the elastic capsule bag and the inner wall of the transformer oil conservator; The air guide assembly is fixedly arranged on the outer wall of the elastic capsule bag at a position close to the through hole, and is extended along the length direction of the elastic capsule bag, so as to prevent the elastic capsule bag from contacting with the transformer reservoir. The top inner wall of the oil tank is fitted. The application can effectively prevent the bonding phenomenon between the capsule and the top inner wall of the transformer oil conservator, and can know this situation in time when gas leakage occurs in the transformer oil conservator, thereby effectively improving the application reliability of the capsule.

Description

technical field [0001] The present application relates to the technical field of power transformers, in particular to a capsule, a transformer oil conservator, and a gas leakage detection method and device. Background technique [0002] During the operation of power transformers, the volume of oil will expand with heat and contract with changes in temperature and load, so the emergence of capsule-type transformer oil conservator meets the needs of daily operation of power transformers. As a capsule oil conservator, its main component is a breathing capsule. By setting a capsule inside the transformer oil conservator, the air is isolated from the transformer oil inside the transformer oil conservator to prevent air damage caused by contact with the air. Deterioration of oil quality. [0003] At present, in the application of the transformer oil conservator, it is necessary to use the gas leak detection device in the oil conservator to detect in real time whether there is gas...

Problems solved by technology

[0004] However, at the initial stage of capsule breakage or poor sealing in the oil conservator, due to the structural problems of the capsules inside the oil conservator and less gas entering the oil conservator from the outside, it is easy to cause the capsules on the inner wall and top of the oil conservator to stick together , so that the gas cannot rise from between the capsule and the inner wall of the oil conservator to the top of the cabinet, so the gas leak detection device will not be able to know this situation in time, which will delay the maintenance of the oil conservator or miss the best maintenance time, and even cause safety hazards. The occurrence or expansion of the accident
