Title:
GAS INSULATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/047851
Kind Code:
A1
Abstract:
This gas insulated apparatus comprises a grounding tank that is partitioned into a plurality of areas each filled with a gas, and a gauge transformer (50) obtained by combining a current transformer (54) for detecting an abnormal current and a voltage transformer (53) for detecting a voltage abnormality. The gauge transformer (50) has an insulating spacer (51) that forms the areas and a main circuit conductor (52) that passes through the insulating spacer (51). The current transformer (54) has an annular shape and the voltage transformer (53) has a shape that forms at least a portion of a ring. The current transformer (54) and the voltage transformer (53) are embedded in the insulating spacer (51) such that the centers thereof are positioned on a center axis of the main circuit conductor (52).
