VOLTAGE DETECTOR OF GAS INSULATION SWITCHGEAR

摘要

PROBLEM TO BE SOLVED: To provide a voltage detector of a gas insulation switchgear capable of adjusting distance between an electrode and a charge part in short time without collecting insulation gas and opening a pressure container.

SOLUTION: A voltage detector 50 includes: an electrode part 4a arranged opposite to a charge part 2 at a state that it does not contact the charge part 2 in a pressure container 1; rod parts 4b and 4c one ends of which are connected to the electrode part 4a and which extend in the axis direction of a branch pipe 10; an insulation support 15 to which the other end parts of the rod parts 4b and 4c are fixed by being penetrated, and which supports the rod parts 4b and 4c by insulation from the pressure container 1 with the electrode part 4a; a lid plate part 14 which is arranged opposite to a flange part 11 provided to the branch pipe 10 in the axis direction and to which the insulation support 15 is fixed; and a bellows part 12 which is attached between the flange part 11 and the lid plate part 14 and can extend in the axis direction.
