Abstract
A power switch module designed to be mounted in gas-filled containers of gas-insulated switchgear is provided, wherein each vacuum switch tube of the power switch has a corresponding rectilinearly movable actuating rod leading into the gas-filled container through a bellows-type seal. The power switch module includes two insulating support devices arranged symmetrically on a partition, between which the corresponding vacuum switch tubes supported by a pole support device and a pole head device. Such power switch modules are used in gas-insulated switchgears.
Claims3
A power switch module mountable in a gas-filled container of gas-insulated switchgears, comprising:
- a vacuum switch tube;
- a rectilinearly movable actuating rod leading into the gas-filled container through a bellows-type seal;
- and
- two insulating support devices having identical profiles to accommodate and shield the vacuum switch tube, the insulating support devices arranged symmetrically about one part of a partition plate forming a portion of the gas-filled container, the insulating devices releasably fastened to the one part of the partition plate, the insulating support devices including:
- two first screw beds having free ends, the first screw beds, via the free ends, arranged symmetrically with respect to a longitudinal axis of a respective one of the insulating support devices for fastening a pole head device which radially support the vacuum switch tube at an outer end area of the vacuum switch tube, and
- two adjacent second screw beds positioned in an inner area of the insulating support devices and opposite to one another with respect to the longitudinal axis for fastening a pole support device which supports the vacuum switch tube at an inner end area of the vacuum switch tube.
