Title:

GAS-INSULATED SWITCHING DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/149230

Kind Code:

A1

Abstract:

The present invention has a configuration such that: a fixed-side terminal (1) is provided with an electric field relaxing shield (12d) at a portion opposite to a movable-side terminal (2); an electric field relaxing shield unit (12) is capable of moving toward the movable-side terminal (2); and functions are separated in such a manner that an energization function is performed by the fixed-side terminal (1) and a function for relaxing an electric field between the terminals is performed by the electric field relaxing shield unit (12). Electric field of a blocking electrode (8) is relaxed in a relatively smaller range than the range between the movable-side terminal (2) and the fixed-side terminal (1), and thus the reignition caused by recovery voltage which increases at open circuit times can be suppressed, thereby enabling the speed for driving the blocking electrode (8) to be lowered.
