Transformer Capsule Oil Conservator

Abstract

The invention discloses a transformer capsule type oil conservator, which comprises an oil conservator and a capsule, and the capsule is arranged in the cavity of the oil conservator body, and is characterized in that the oil conservator is provided with a pipeline interface I and a pipeline Interface II, the pipeline interface I communicates with the cavity of the oil conservator, the pipeline interface II communicates with the capsule and the pipeline interface II and the capsule are sealed and connected; the pipeline interface I communicates with the union through the pipeline I and connects The joint of the pipeline II is connected to the joint pipe through the pipeline II and the joint is sealed, the valve I is set on the pipeline I, and the valve II is set on the pipeline II; the joint pipe is connected to the moisture absorber through a connecting pipe and the moisture absorber and The connecting pipes are detachably connected, and the inner diameter of the pipeline I is larger than that of the pipeline II. It can fully realize the integrated vacuuming of the transformer oil conservator and the capsule, and at the same time ensure that the pressure inside and outside the capsule is the same without causing damage; the vacuum tube is shared with the moisture absorber joint tube, which simplifies the structure, saves materials, and is convenient and quick for vacuum oiling.

Description

technical field [0001] The invention relates to the electric power industry, in particular to a transformer oil conservator, in particular to a transformer capsule oil conservator. Background technique [0002] In order to effectively reduce the air bubbles and moisture in the transformer body and oil, improve the insulation level of the transformer and the electrical performance of the oil, the vacuum oiling process is now used. There are three types of vacuum oil filling in the current technology: the first is oil filling without an oil conservator, this oil filling method is to make the oil filling in the oil conservator under normal pressure, but it will cause some gas in the oil conservator and moisture will be integrated into the transformer, which will bring hidden dangers to the operation of the transformer; the second method is to fill oil with an oil conservator that is not resistant to vacuum. After the vacuum structure, the oil conservator is still filled with o...

There are three types of vacuum oil filling in the current technology: the first is oil filling without an oil conservator, this oil filling method is to make the oil filling in the oil conservator under normal pressure, but it will cause some gas in the oil conservator and moisture will be integrated into the transformer, which will bring hidden dangers to the operation of the transformer; the second method is to fill oil with an oil conservator that is not resistant to vacuum. After the vacuum structure, the oil conservator is still filled with oil under normal pressure, which will also cause problems like the first oil filling method; the third method is to fill oil together with the vacuum-resistant oil conservator, which is the real way The full vacuum oiling can minimize the gas and water content in the oil, but the capsule of the capsule oil conservator is made of rubber, if the pressure difference between the inside and outside of the capsule is large when the oil conservator is in vacuum, the capsule will be damaged, causing The gas and impurities in the capsule enter the main body of the oil conservator, accelerating the aging of transformer oil

[0003] When the oil conservator is evacuated, the vacuuming pipes in the oil conservator are used, which takes a long time and is not fast enough; there are also pipes for the moisture absorber, oil injection pipes, and oil delivery pipes in the oil conservator, and the pipes are relatively Many and miscellaneous
