Description

Drainage tube of transformer pressure releaser

Technical Field

The utility model relates to the technical field of transformer pressure releasers, in particular to a drainage tube of a transformer pressure releaser.

Background

The pressure releaser is used as a safety component of the power transformer, and the reliable action of the pressure releaser is particularly important when the power transformer fails in operation. The pressure releaser is generally arranged on an oil tank of the transformer in the large and medium-sized transformers, and the transformer oil is protected from the outside air when the transformers work normally. When the transformer is in short circuit fault, the winding of the transformer will generate arc and spark, so that the transformer oil instantaneously generates a great amount of gas, the pressure in the oil tank is increased, when the pressure reaches the set pressure, the pressure releaser is opened to release the pressure, and the transformer is automatically closed after the pressure is released. Thus, the transformer oil tank is not deformed and exploded due to excessive pressure.

At present, the traditional transformer pressure releaser is provided with a drainage tube which can drain the gasoline in the transformer, so that the situation that the gasoline is sprayed everywhere when the pressure is released can be prevented, but the traditional drainage tube is not well fixed, and unstable factors such as air pressure can cause the drainage tube to shake when the pressure is released, so that the transformer pressure releaser is quite unsafe and needs to be improved.
