Abstract
Official abstract text for this publication.
Disclosed is a power switch gear that includes: a fixed electrode and a movable electrode disposed opposite to each other in a tank filled with insulting gas; and a movable conductor electrically connecting the fixed electrode and the movable electrode together. The fixed electrode and the movable electrode have a contactor through which current flows to the movable conductor. At least one of the fixed electrode and the movable electrode has ring-shaped sliding members, the ring-shaped sliding members being disposed, on both sides of the contactor. At least one grease pool is provided between the contactor and the sliding members.
First claim
Opening claim text (preview).
What is claimed is: 1. A power switchgear comprising: a fixed electrode and a movable electrode disposed opposite to each other in a tank filled with insulting gas; and a movable conductor electrically connecting the fixed electrode and the movable electrode together; wherein the fixed electrode and the movable electrode each have a contactor through which current flows to the movable conductor; wherein at least one of the fixed electrode and the movable electrode has ring-shaped sliding members, the ring-shaped sliding members being disposed on both sides of the contactor; wherein at least one grease pool is provided between the contactor and the sliding members; and wherein the at least one grease pool is provided with at least two holes that radially pass through the fixed electrode or the movable electrode. 2. A power switchgear comprising: a fixed electrode and a movable electrode disposed opposite to each other in a tank filled with insulting gas; and a movable conductor electrically connecting the fixed electrode and the movable electrode together; wherein the fixed electrode and the movable electrode each have a contactor through which current flows to the movable conductor; wherein the fixed electrode and the movable electrode each have ring-shaped sliding members on both sides of the contactor; wherein one of the ring-shaped sliding members, provided to the fixed electrode and located close to the movable electrode, is arranged in a shape tapered along an opening of the fixed electrode, the opening facing the movable electrode; wherein at least one groove provided as a grease pool is disposed between the contactor and the sliding members; and wherein the at least one grease pool is provided with at least two holes that radially pass through the fixed electrode or the movable electrode.
