Electromagnetic Voltage Transformer External Structural Components
Apr 04, 2018

All high-voltage voltage transformers have three parts: the head, the bushing and the base.

     (1) The head connects transformers and lines. All forms of transformers must have a lead terminal and its logo. The oil immersed transformer is also equipped with an expander and the SF6 transformer is equipped with a rupture disk.

     (2) The bushing is the outer insulation of the transformer. Casting transformers use insulation instead of casing insulation. The design of the bushing must take into account the over-voltage level of the transformer itself, the environmental contamination conditions in which the transformer is operated, the mechanical forces, etc. At the same time, the coordination with the body, base and head must also be considered.

     (3) The base supports the function of the fixed transformer body. The base plate must have a nameplate, secondary lead terminals, grounding terminals, mounting holes, oil drain (or deflation) valves, SF6, transformer pressure gauges and gas density relays.
