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

Abstract

The embodiment of the invention provides a capsule, a transformer oil conservator and a gas leakage detection method and device. The capsule comprises an elastic capsule bag and a gas guide componentwhich are arranged in the transformer oil conservator; the inner cavity of the elastic capsule bag communicates with the outside of the transformer oil conservator through a through hole formed in thetop of the transformer oil conservator, and a sealed oil containing cavity is formed between the outer wall of the elastic capsule bag and the inner wall of the transformer oil conservator. The air guide component is fixedly arranged at the position, close to the through hole, of the outer wall of the elastic capsule bag and extends in the length direction of the elastic capsule bag so as to prevent the elastic capsule bag from being attached to the inner wall of the top of the transformer oil conservator. According to the transformer oil conservator, the phenomenon that the capsule is attached to the inner wall of the top of the transformer oil conservator can be effectively avoided, the situation can be known in time when gas leakage happens to the transformer oil conservator, and thenthe application reliability of the capsule can be effectively improved.

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
