Embodiment Construction

[0045] The invention is a joint simulation model of the kinematic characteristics of a permanent magnet operating mechanism circuit breaker, which specifically includes the following steps:

[0046] First, the main components of the permanent magnet operating mechanism are simulated and modeled for the electromagnetic transient field through Ansoft Maxwell software. The Ansoft Maxwell software is used for electromagnetic transient field simulation modeling, including modeling of yoke, moving iron core, permanent magnet and coil, and the material properties, coil turns and number, magnetic field direction, and network Grid partitions are defined. The described electromagnetic transient field simulation modeling setup allows co-simulation with Ansoft Simplorer software. The Ansoft Simplorer software performs control system simulation modeling, including equivalent capacitors, resistors and contactors. The Ansoft Simplorer software establishes a joint simulation model of the perm...
