Abstract: In an operating device for high voltage gas blast circuit breakers, the opening impulse is transmitted from earth to high potential by means of an insulating tension rod. A high initial acceleration of the rod is obtained by suddenly evacuating a pressurized cylinder space at earth potential through an electrodynamically operated valve.
