Electrical pressure gas circuit breaker with mechanical compression - quenches gas and has conductor through which current flows in longitudinal direction surrounded by at least one ferromagnetic body

摘要

The at least one ferromagnetic body (12,13,22) extending longitudinally over the conductor (2) has at least one intermediate space (14,15) extending in the longitudinal direction of the conductor (2), across the entire length of the body (12,13,22). It completely penetrates the body in a radial direction, in which a bar (8,9) of ferromagnetic material connected to the compression cylinder (4) to be driven can be applied in a longitudinal direction contact free. A guide (18,19) is provided for the rods (8,9). This prevents movements of the rods (8,9) parallel to the direction of the magnetic flux in the body (2). USE/ADVANTAGE - Electric pressure gas circuit breaker. Use of electromagnetic forces produced by the switch interruption permits simple and compact construction.
