TRANSFORMER AND SEALED SWITCH GEAR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To attach an instrument transformer to a sealed switch gear without storing the transformer in a gas room and to improve the safety and reliability of the transformer in a compact constitution reducing the number of components.

SOLUTION: A grounded conductive layer 2 is formed on the surface of a transformer 1 molded with an insulator and at least two or more input terminals 5a, 5b insulated from the conductive layer 2 and allowed to be connected to a main circuit charging part 4 of the transformer 1 are formed almost in parallel with each other on the opposite side to the fixing surface 3 of the transformer 1.
