Problems solved by technology

[0005] However, since the diameters of the threaded connection type oil level gauge and the flange connection type oil level gauge are different, the hole diameters of the tank cover for installing the threaded connection type oil level gauge and the flange connection type oil level gauge also need to be set differently. For the same two, when producing the box cover, two different holes are opened on the box cover, which increases the processing steps of the box cover, which brings inconvenience to the production
And when connecting the oil level gauge, only the matching hole is used, and the other hole needs to be blocked, which means that the blocked hole is useless in use, which is also not conducive to the sealing and use of the transformer

Abstract

The invention provides a connecting structure of a transformer tank cover and an oil level indicator and a transformer with the connecting structure, and belongs to the technical field of transformers, the connecting structure of the transformer tank cover and the oil level indicator comprises a mounting hole formed in the transformer tank cover, and the mounting hole is suitable for being connected with a first flange and a second flange; the first flange is a threaded flange suitable for being connected with a threaded connection type oil level indicator, and a first positioning flange is arranged on one surface of the first flange; the second flange is a flange suitable for being connected with a flange connection type oil level indicator, and one surface of the second flange is provided with a second positioning flange. According to the connecting structure of the transformer tank cover and the oil level indicator, good interchangeability and deployment, installation and use of anyone of a full-sealed transformer and a transformer with an oil conservator are achieved; and the processing steps of the box cover are simplified, so that the production is more convenient.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a connection structure between a transformer case cover and an oil level gauge and a transformer having the same. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. [0003] Transformers include: fully-sealed transformers and transformers with oil conservator; the fully-sealed transformers need to be installed with an oil level gauge, and the oil level gauge needs to be drilled on the cover of the transformer during installation, and fixed with the cover of the transformer through the flange Connection; when installing the oil conservator for a transformer with an oil conservator, it is necessary to drill holes in the cover, and connect the oil outlet pipe of the oil conservator to the cover of the transformer through the flange. [0004] In the prior art, there are generally two types of oil le...
