电磁脱扣器及应用该脱扣器的剩余电流动作断路器
摘要：
本发明公开了一种电磁脱扣器，包括一个磁轭、一个设置在所述磁轭上的磁铁、一个与所述磁铁连接的静铁芯、一个能够相对所述静铁芯运动的动铁芯、一个套设在所述动铁芯上的线圈；所述电磁脱扣器还包括一个导磁体；所述磁铁具有一个分磁路径；所述分磁路径经过所述静铁芯、所述导磁体、所述磁轭回到所述磁铁。本发明还公开了一种使用该电磁脱扣器的剩余电流动作断路器。通过设置导磁体使得磁铁具有一个分磁路径：经过所述静铁芯、所述导磁体、所述磁轭回到所述磁铁，因此，通过结构尺寸的调整，可以调整磁铁的主磁路径和分磁路径的磁通量大小，从而控制对动铁芯的吸合力大小。
摘要（英）：

The invention discloses an electromagnetic trip. The electromagnetic trip comprises a magnet yoke, a magnet arranged on the magnet yoke, a static iron core connected with the magnet, a movable iron core which can be moved relative to the static iron core, and a coil sleeved onto the movable iron core. The electromagnetic trip further comprises a magnetizer. The magnet is provided with a branch magnetic path. The branch magnetic path passes through the static iron core, the magnetizer and the magnet yoke and then returns to the magnet. The invention further discloses a residual current operated circuit breaker adopting the electromagnetic trip. By arranging the magnetizer, the magnet is provided with a branch magnetic path which passes through the static iron core, the magnetizer and the magnet yoke and then returns to the magnet, so through structure size adjustment, the magnetic flux of a head magnetic path and the branch magnetic path of the magnet can be adjusted so as to control the attraction force on the movable iron core.
