    • 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.
    • 本发明提供一种具有用于电弧抑制的接触保护电路的开关装置。 开关装置包括用于中断负载路径的主继电器和具有操作辅助触点的切换的高电阻线圈和低电阻线圈的双线圈辅助。 辅助触点与PTC器件和辅助继电器的低电阻线圈串联连接。 串联装置与主触点并联连接。 当主继电器打开时,由于低电阻线圈产生的磁通量,辅助触点在给定的时间间隔内保持关闭。 给定的时间间隔取决于PTC设备到跳闸状态的转换。 在另一种配置中,双线圈继电器由两个辅助继电器代替。

    • 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.
    • 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。
