Abstract

PURPOSE:To make unnecessary large-sized insulator in air, by providing conductors connected to power equipment and to coupling capacitor, in the bushing connected to gas insulation switching equipment. CONSTITUTION:The power line 3 is connected to the conductor 21 of the gas insulation equipment 9 via the lead wire 2, the blocking coil 1, and the first conductor 18 in the bushing 12. High frequency signal propagated on the power line 3 is coupled with the power line carrying communication equipment via the lead wires 2, 25, the second conductor 22 and coupling capacitor 6. Since the first and second conductors are contained in the bushing 12, large-sized insulator in air is made unnecessary.
