Magnetic actuator for a circuit breaker arrangement

摘要

An exemplary magnetic actuator for a circuit breaker arrangement includes a coil, a core with a groove for accommodating a section of the coil, and a movable plate configured to be attracted by the core. When a magnetic field is generated by the coil, the movable plate actuates the circuit breaker arrangement based on the attraction to the core. The magnetic actuator also includes a position locker for locking the coil in the groove. The position locker having a locking part protruding away from the core and over a section of the coil not accommodated in the groove.

1. A magnetic actuator for a circuit breaker arrangement, the magnetic actuator comprising:
a coil; a core with at least one groove for accommodating a section of the coil; a movable plate configured to be attracted by the core such that when a magnetic field is generated by the coil, the movable plate actuates the circuit breaker arrangement based on the attraction to the core; a fixed axis member extending axially through the movable plate, and wherein the fixed axis member extends through a central part of the core and is fixed to the core such that the movable plate can only move towards the core and away from the core; and a position locker for locking the coil in the at least one groove, wherein first and second grooves are formed between upper parts of a first flank and a central part of the core, and a second flank and the central part of the core, respectively, and wherein the first groove is limited by an inner side of the upper part of the first flank and a side of the upper part of the central part facing the side of the first flank, and the position locker has a locking part protruding away from the core and over a section of the coil not accommodated in the at least one groove.
