METHOD FOR CONTROLLING A CONTACTOR DEVICE, AND CONTROL UNIT |
摘要 |
The present disclosure relate to a method 50 performed in a control unit 12 for opening a contactor device 1. The contactor device 1 comprises a carrier 8 being movable between a closed position in which a current is allowed to flow in a current path and an open position in which the current path is broken. The control unit 12 is configured to enable the movement of the carrier 8 between the closed position and the open position by energizing a coil 6 of an electromagnetic circuit. The method 50 comprises: initiating 51 the opening of the contactor device 1 by de-energizing the coil 6, wherein the de-energizing comprises using a demagnetization circuit 40 comprising a discharge element 37, the discharge element 37 being arranged to consume energy in the coil 6; bypassing 52, at a first point of time, the discharge element 37; and re-energizing 53 the coil 6. |
