Title:
The gas insulation instrument transformer which has an opening device
Document Type and Number:
Japanese Patent JP6239126
Kind Code:
B2
Abstract:
A gas-insulated measurement transformer for measuring high voltages has a plurality of transformer arrays arranged in a fluid-tight housing for transforming a high voltage to a measurement voltage. Each of the arrays has an active part, a high voltage contact guided through the housing, a fixed contact that is electrically connected to the active part, a movable contact that is electrically connected to the fixed contact, and a separating device, which can be operated from outside the housing, for establishing or separating a connection between the movable contacts and the high voltage contacts. The separating device has a connecting element connecting the movable contacts to one another, and an adjustment device for moving the connecting element in an actuating direction, wherein the fixed contact is configured as a guiding device for the movable contact in an actuating direction.
