Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an oil tank of a seismic-resistant power transformer. Background Art

[0002] The oil pillow of the earthquake-resistant power transformer is installed on the oil tank (corrugated oil tank) of the transformer. There is also a pipe sealed with "glass", called "explosion-proof pipe", which is to prevent the oil temperature from rising rapidly and the volume from expanding sharply when the earthquake-resistant power transformer fails. When the oil pillow can no longer hold the oil, the oil flow will break the glass and rush out of the explosion-proof pipe to protect the transformer from serious damage. The types of earthquake-resistant power transformer oil tanks can be classified according to the purpose and installation environment of the transformer, such as outdoor oil tanks, indoor oil tanks, etc. In addition, the design and manufacture of the oil tanks need to comply with relevant standards and specifications to ensure the safe and reliable operation of the transformer. In practical applications, the quality and performance of the oil tank have an important impact on the overall performance and service life of the transformer.

[0003] In combination with the above content, it should be explained that: during the use of traditional earthquake-resistant power transformers, the oil tank is easily affected by various factors such as external vibration, environmental changes and abnormal use of the internal transformer, which may cause the explosion-proof pipe to burst. The spilled oil may easily cause a sudden change in the transformer installation environment, affecting subsequent maintenance and use. In addition, earthquake-resistant power transformers that lack oil cooling have great safety hazards in subsequent use.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
