Abstract
The utility model provides an electromagnetic device of a breaker and relates to the technical field of breakers. The device is installed in a housing of a breaker and comprises a magnet yoke surrounded on three sides. One end of the magnet yoke is provided with an extension for fixing a coil bobbin, and the other end is provided with a notch for snap installation of a stationary contact rod provided with a contact. The stationary contact rod is in a U shape and comprises a rhombic tail. The stationary contact rod is in one piece and is provided with a snap installation part corresponding to the notch in the magnetic yoke. The magnetic yoke is provided with positioning clamp feet. The provided novel magnetic yoke surrounded on three sides can position and fix the coil bobbin and facilitates coil bobbin dismounting and iron core spring replacement, and at the same time, a push rod in an iron core do not fall off. The tail for arc running employs a rhombic design, which substantially improves arc ignition effect, reduces arc dead time, and helps an arc enter an interrupter. Snap installation is employed to assemble the magnetic yoke and the static iron core, so that the production efficiency is improved.
