摘要： The present invention relates to contactors for unidirectional DC operation with permanent magnetic arc extinguishing. In addition to the blow magnets, the contactors are equipped with compensatory permanent magnets for compensating the magnetic field in the vicinity of the contact bridge in order to prevent contact levitation, i.e., an uncontrolled opening of the contacts that is due to a magnetic force generated by a strong current flowing through the contact bridge. To this end, the compensatory permanent magnets are arranged in the vicinity of the contact bridge and polarized in the opposite direction of the blow magnets. The magnetic field of the compensatory magnets and the current flowing through the contact bridge are generating a magnetic force that acts on the contact bridge and tends to keep the electrical contacts closed.
摘要翻译：本发明涉及用于具有永久磁性灭弧的单向直流操作的接触器。除了吹制磁体之外，接触器还配备有补偿永磁体，用于补偿接触桥附近的磁场，以防止接触悬浮，即由于产生的磁力引起的触头的不受控的打开通过流过接触桥的强电流。为此，补偿永久磁铁布置在接触桥附近，并沿着吹塑磁体的相反方向极化。补偿磁体的磁场和流过接触桥的电流产生作用在接触桥上的磁力，并且趋向于保持电触点闭合。

摘要： The invention provides a switching device having a contact protection circuit for arcing suppression. The switching device comprises a main relay for interrupting a load path and a dual coil auxiliary having a high resistance coil and a low resistance coil that operate the switching of an auxiliary contact. The auxiliary contact is connected in series with a PTC device and the low resistance coil of the auxiliary relay in a series arrangement. The series arrangement is connected in parallel to the main contact. When the main relay opens, the auxiliary contact is maintained closed during a given time interval due to the magnetic flux generated by the low resistance coil. The given time interval depends on the transition of the PTC device to trip state. In another configuration, the dual coil relay is substituted by two auxiliary relays.
