Transformer switch oil tank structure and transformer

Abstract

The invention provides a transformer switch oil tank structure and a transformer, and relates to the field of electrical equipment. The transformer switch oil tank structure comprises a transformer oil chamber, a switch oil chamber and a transformer switch. The transformer switch is placed in the switch oil chamber, the switch oil chamber is placed in the transformer oil chamber, and the top wallof the switch oil chamber is connected to the inner side of the top wall of the transformer oil chamber and connected to the middle position of the top wall of the transformer oil chamber. The transformer switch is flat and placed horizontally in the switch oil chamber. According to the transformer switch oil tank structure, the switch oil chamber is added in the transformer oil chamber, so that the switch oil chamber is separated from the transformer oil chamber. At the same time, the flat transformer switch is adopted, so that the switch oil chamber can utilize the space in the transformer oil chamber more effectively. A lead is reasonably stretched in layout, the transformer insulation level is improved, the transformer cost is reduced, and the application range of the transformer is expanded.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a transformer switch oil tank structure and a transformer. Background technique [0002] At present, the capacity adjustment (voltage adjustment) switch commonly used in transformers is generally a tumbler structure, the static contact is installed on the circumference of the tumbler, the moving contact is fixed on the support of the middle main shaft, and the tumbler is formed into an independent oil chamber. The (voltage regulating) switch is vertically arranged on the side wall of the transformer, and the motor is arranged on the top of the transformer; it is connected with the winding taps and the incoming and outgoing lines of the transformer through connecting wires. [0003] This structure makes the entire transformer larger in size and higher in cost, and the layout of the capacity regulating (voltage regulating) switch and the lead wires of the transformer is more com...

AI Technical Summary

Problems solved by technology

[0003] This structure makes the entire transformer larger in size and higher in cost, and the layout of the capacity regulating (voltage regulating) switch and the lead wires of the transformer is more complicated. Especially for large-capacity transformers, the lead wires are thicker and larger, which makes the layout in a limited oil tank very tense. Insulation is difficult to guarantee
