OPERATING DEVICE FOR ELECTRIC SWITCHING APPARATUS FOR HIGH VOLTAGE

摘要

In an operating system 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 means of an electro-dynamic operating device positioned at the lower end of the rod. This operating device comprises a stationary coil and an operating plate connected inductively to the coil and directly joined to the tension rod.
