The present invention is related to an operating device (200) for driving and controlling the opening and closing of an electrical high voltage or medium voltage switching apparatus, such as a switch or a circuit breaker. The operating device comprises a rotating electric machine (201) which is operatively connected to a mobile contact (203) of the switching apparatus. The rotating electric machine (201) operates the mobile contact via a mechanical coupling (202) upon receiving control signals (208) from a control unit (205). The rotating electric machine (201) may, upon a decelerating motion of the mobile contact (203), transform the kinetic energy of the mobile contact (203) into electrical energy which can be transferred to a suitable energy storage or supply unit (204). The operating device according to the invention is especially suited to operate circuit breakers of all types.
An operating device for a rapid operation of a medium voltage or a high voltage switching apparatus having at least one mobile contact, comprising:
A method for a rapid opening or closing motion of a medium voltage or a high voltage switching apparatus having at least one mobile contact and an operating device including a rotating electric machine in operational connection with the at least one mobile contact and an energy supply unit, comprising:
An operating device for a rapid operation of a medium voltage or a high voltage switching apparatus having at least one mobile contact, comprising:
