The power transmission equipment in the substation mainly includes transformers, high-voltage circuit breakers, disconnectors, busbars, lightning arresters, capacitors, reactors, etc. Among them, the transformer is the core equipment of the substation. Transformers are divided into dry-type transformers and oil-immersed transformers.
