Abstract (en)
[origin: DE19815538A1] The invention relates to drive devices for interrupter units in power supply and distribution switching units, especially for vacuum circuit breakers in medium voltage switching devices. Said drive devices comprise lifting devices (HA) controlled by a magnetic coil drive for actuating the movable contact members of the switching devices by means of coupling bars. Each switching device is fitted with at least one pole member and a drive member. Each magnetic coil drive has a movable armature and an on coil and an off coil. The magnetic coil drives of the interrupter units are replaced by linear motor drives (LA) whose integrated lifting devices (HA) directly bring about gearless actuation of the movable contact parts of the switching devices. The movements relevant to switching can be influenced by a control unit optimizing the switching operation. Said drive devices are used in interrupter units for power supply and distribution switching devices.
