Capsule type oil storage cabinet of transformer

Abstract

The invention discloses a capsule type oil storage cabinet of a transformer. The capsule type oil storage cabinet of the transformer comprises an oil storage cabinet body and a capsule. The capsule is arranged in a cavity of the oil storage cabinet body. The capsule type oil storage cabinet is characterized in that the oil storage cabinet body is provided with a pipeline connector I and a pipeline connector II; the pipeline connector I is connected with the cavity of the oil storage cabinet body; the pipeline connector II is connected with the capsule and is hermetically connected with the capsule; the pipeline connector I is connected with a pipe connector through a pipeline I and a connection position is sealed; the pipeline connector II is connected with the pipe connector through a pipeline II and a connection position is also sealed; the pipeline I is provided with a valve I; the pipeline II is provided with a valve II; the pipe connector is connected with a moisture absorber through a connecting pipe; the moisture absorber is detachably connected with the connecting pipe; and the inner diameter of the pipeline I is greater than that of the pipeline II. The oil storage cabinet of the transformer and the capsule are vacuumized integrally; the pressure of the inside of the capsule is the same with the pressure of the outside of the capsule, so that the capsule cannot be damaged; a vacuumizing pipe and the moisture absorber share the pipe connector; the structure is simplified; materials are saved; and vacuum oil injection is performed conveniently and quickly.

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
