摘要： An electrical high-tension circuit breaker with main contacts and auxiliary contacts in parallel to the main contacts. Both sets of contacts are actuated by hydraulic drives which are fed from a hydraulic accumulator. The drive of this circuit breaker is of high reliability and small size considering the power to be switched. This is achieved with a main drive which contains a piston-cylinder arrangement which can be pressurized with hydraulic fluid via a main valve and a secondary drive which is actuated via a valve arrangement. The valve arrangement is controllable as a function of the position of the main contacts and/or the auxiliary contacts. With this drive, failure-susceptible elements, such as catches, mechanical dampers and couplings, are avoided. The drive is preferably for high-tension circuit breakers for voltages above 220 kV.
