    • A protective device is disclosed for combination with an electrical switching device including a main current line or for integration in such a switching device. In at least one embodiment, the protective device includes a switching element and a switching apparatus, which is provided for the actuation of the switching element and is influenced by a current flow through the main current line. In at least one embodiment, in order to influence the switching apparatus, a current transformer is integrated in the main current line and an electrical resistance of a secondary winding surrounded by the current transformer can be measured. A method for operating a protective device is also disclosed wherein the switching apparatus is triggered so as to actuate the switching element if the measured resistance reaches or exceeds a predetermined or predeterminable threshold value.
    • 公开了一种与包括主电流线或用于集成在这种开关装置中的电开关装置组合的保护装置。 在至少一个实施例中,保护装置包括开关元件和开关装置,其被设置用于致动开关元件并且受到通过主电流线的电流的影响。 在至少一个实施例中,为了影响开关装置,电流互感器集成在主电流线中,并且可以测量由电流互感器包围的次级绕组的电阻。 还公开了一种用于操作保护装置的方法,其中如果所测量的电阻达到或超过预定或可预定的阈值,则开关装置被触发以便致动开关元件。

    • An electromechanical switch includes a main contact provided with a number of main fixed contacts and a mobile main contact bridge; an auxiliary contact which precedes the main contact in the switch-on process and includes a number of auxiliary fixed contacts and a mobile auxiliary contact bridge; and a contact bridge carrier for actuating the main contact bridge and the auxiliary contact bridge. At least one of the contact parts is spring-mounted. The electromechanical switch has two stable positions of the auxiliary contact bridge or the auxiliary fixed contact. During the switching on process carried out by actuation of the contact bridge carrier via the auxiliary contact bridge or an auxiliary fixed contact in the first stable position, the auxiliary contact closes before the main contact, and during the switching off process by actuation of the contact bridge carrier in the opposite direction, the auxiliary contact with the auxiliary contact bridge or the auxiliary fixed contact in the second stable position opens before the main contact.
    • 一种机电开关包括:主触点,设置有多个主固定触点和移动主触点桥; 在接通过程中在主触点之前的辅助触点,并且包括多个辅助固定触点和移动辅助触点桥; 以及用于致动主接触桥和辅助接触桥的接触桥架。 至少一个接触部件是弹簧安装的。 机电开关具有辅助触点桥或辅助固定触点的两个稳定位置。 在通过辅助接触桥或辅助固定接触件在第一稳定位置致动接触桥式载体进行的接通过程中,辅助触点在主接触之前闭合,并且在断开过程期间通过触点的致动 桥架相反方向,与辅助接触桥的辅助接触或辅助固定触点在第二稳定位置在主接触之前打开。
