| Abstract: | Based on Ansoft Maxwell 2D simulation environment,this paper uses a fast electromagnetic tripping mechanism to establish a simulation model for the designed new protection device for voltage transformers,and makes a simulation study on static and dynamic characteristics of the electromagnetic tripping mechanism in this environment under the conditions of different fault currents and numbers of excitation coils.The strength of electromagnetic force exerted on the electromagnetic slider in the tripping device is thus obtained for different numbers of ampere turns,thus providing a theoretical basis for the design of the new type PT protection device.Furthermore,through comparison between simulation results and theoretical calculation of electromagnetic force,the correctness of the simulation result is verified. |
