The operating shaft is rotable at least between two positions and has a coupling part. The motor operator 6 comprises a housing 10, which is mountable on the external surface of the switchgear housing, and a rotatable connection shaft connected to an electric motor drive mechanism. It has a first coupling part to fit with the coupling part of the switchgear in a longitudinal axial sliding and non-rotational interlocking manner. Further, it has a second coupling part extending from the housing to operate the switch manually. The operator further comprises a control unit 8 with a connection rack, one or more power supplies, besides from a battery 9, and one or more communication facilities 9, such that the motor operator appears self-contained with all necessary facilities ready to operate when installed.

摘要： A circuit breaker with electrical contacts adapted to open or close thereby preventing or allowing respectively current to be supplied from one part of an electrical system to a further part of the electrical system. The circuit breaker is provided with a storage device for storing data indicative of the zero crossing points of the current signal and an actuator arrangement for causing the electrical contacts of the circuit breaker to be opened or closed in accordance with the data indicative of the zero points of the current signal. The system synchronises the zero energy state of the a.c. system with the rapid opening of the contacts thereby circumventing an arc in the circuit breaker. preferably, the actuator is an electrical linear motor whose armature is provided with a position detector to provide feedback control of the motor.

摘要： The invention concerns a circuit-breaker control device designed to open and close said electric power interrupting device comprising a mobile contact said control device including a motor (3) with rotary output shaft (12) and being connected to power supply means (4 to 9) and actuating means transforming the motor output displacement into a contact displacement, said device further including a mechanical spring arrangement contributing to the opening and closure of the contact. The invention is characterized in that the actuating means comprise as assembly of articulated elements for linking the rotary shaft and the ring, and when the contact is in closed position, the assembly of articulated elements is proximate a dead center position called opening dead center, the opening spring (15) not being capable of driving it towards the opening position until it passes beyond said dead center position when said contact is being opened.

摘要： In a magnetic linear drive, a coil (10, 11) is provided, inside which a magnetic flow (13) can by produced by a current in axial direction (34). Said drive comprises an armature (1) that can only move perpendicular in relation to the axial direction (34) and that includes a magnetically active part (3) that is magnetized in a particularly antiparallel manner in relation to the axial direction (34). The armature is driven by a current impulse that accelerates said armature in the direction of the center of the coil independently of the starting position of the magnetically active part (3).

摘要： In a power distribution system, synchronizing switchgear operations with an AC voltage or current waveform can be accomplished more precisely with a closed-loop feedback, microprocessor-based motion control design. By employing a closed-loop feedback, microprocessor-based design, switchgear contact position and velocity can monitored and optimized in real-time during a switching operation, thereby assuring a more accurate switching operation. Moreover, the closed-loop feedback design intrinsically compensates for the affects of such things as ambient temperature, AC waveform fluctuations, and changes in the physical condition of the switchgear. The closed-loop position feedback design is also capable of optimizing various transfer function parameters associated with the closed-loop feedback process, both during and subsequent to a switching operation, to further assure that switching operations are more accurately synchronized with the AC voltage or current waveforms.
