    摘要: This publication discloses a switching device combination for capacitive loads (3) connected to a direct voltage. The switching device combination includes an actual switch component (1) for connecting voltage to the capacitive load (3), a charging switch component (2) for connecting charging voltage to the capacitive load in the initial stage, which charging switch component is dimensioned for a lower current than the actual switch component (1), a controller component (4), by means of which the actual switch component (1) is controlled from an open state to a closed state and vice versa, with the aid of a mechanical lever (5), which is connected to a first shaft (6), and delay elements (11) for delaying the connection of the actual switch component (1), so that the closed charging switch component (2) will have time to charge the capacitive load (3) before the connection of the actual switch component (1). According to the invention, the controller component (4) includes a second shaft (7), which is operationally connected to the first shaft, in order to control the charging switch component (2).

    摘要: An electronic auxiliary contact for a contactor has at least one switch element controllable to the conducting and non-conducting states for the purpose of indicating the position of the contact bridging member in the contactor, and a switch-activating element mechanically connected to the contact bridging member and capable of activating the switch element. The switch-activating element incorporates at least one activating element, and the switch-activating element makes no mechanical contact with the switch element. The system provides a reliable method of monitoring the operation of a contactor.

    摘要: A system having an electric machine, memory device for storing information concerning the electric machine and is attached to the electric machine, and at least one control unit for controlling the operation of the electric machine. Furthermore, the system of the present invention has an interface between the memory device and the at least one control unit so that the at least one control unit reads the information stored in the memory device. The control unit processes the information read from the memory device such that the information becomes verified with default parameters of the system after read-out-thereof. In case the information includes parameters, which do not match in a predefined manner with the default parameters, the control unit is arranged to either automatically, adjust the system in accordance with the information received from the memory device or to prevent start-up of the electric machine or the entire system.
