Abstract

The invention relates to an electromagnetic device of a breaker, belonging to the technical field of breakers. The electromagnetic device is mounted in a breaker housing, and comprises a magnet yoke, wherein three sides of the magnet yoke are surrounded, an extension portion through which a coil skeleton is fixed is arranged at one end of the magnet yoke, a gap which is clamped with a static contact rod is arranged at the other end of the magnet yoke, and the static contact rod is equipped with a contact; the static contact rod is U-shaped and comprises a rhombic tail portion; and the integrated static contact rod is also equipped with a clamping portion whose shape corresponds to the shape of the gap of the magnet yoke, and the magnet yoke is equipped with positioning clamp pins. According to the invention, the magnet yoke whose three sides are surrounded can position and fix the coil skeleton, so that the coil skeleton can be conveniently dismounted, a spring of an iron core can be conveniently replaced, and an push rod in the iron core does not fall off; the rhombic tail portion of the static contact rod greatly improves the arc ignition effect, shortens the arc stagnation time, and enables arcs to enter an explosion chamber; and the magnetic yoke is clamped with the static iron core to improve the working efficiency.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to electromagnetic devices of circuit breakers. Background technique [0002] In the existing electromagnetic device of circuit breaker, it is inconvenient to disassemble the coil frame and replace the iron core spring. At the same time, the ejector rod in the iron core is easy to fall off, the effect of arc ignition is not good, and the production efficiency is low. Contents of the invention [0003] The object of the present invention is to provide an electromagnetic device for a circuit breaker to solve the technical problems that the above-mentioned electromagnetic mechanism has poor self-arcing effect and low production efficiency. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an electromagnetic device for a circuit breaker, which is installed in the housing of the circuit breaker and includes a m...
