Description

Technical Field

[0001] The utility model relates to a transformer oil storage cabinet device, in particular to a transformer oil storage cabinet device based on built-in oil. Background Art

[0002] The transformer oil conservator, commonly known as the oil pillow, is a cylindrical container placed horizontally above the oil tank and connected to the transformer's oil tank with a pipe. When the transformer oil expands due to heat, the oil flows from the oil tank to the oil conservator; when the transformer oil contracts due to cold, the oil flows from the oil conservator to the oil tank. Therefore, the transformer oil conservator device is an important transformer component. Among the existing transformer oil conservator devices, there is no transformer oil conservator device based on built-in oil. The corrugated expansion tubes storing transformer oil are placed in cabinets under normal air pressure. When the corrugated expansion tube is in a full position, a lot of pressure will be generated on the corrugated expansion tube. In order to ensure the safety performance of the corrugated expansion tube, the storage capacity of the corrugated expansion tube for transformer oil is affected.

[0003] The utility model has the technical feature of placing the transformer oil storage bladder in a vacuum state, and has effectively explored and studied the technical problem that the corrugated expansion tube storing transformer oil is placed in a cabinet under normal air pressure and a large pressure is generated on the corrugated expansion tube.
