| Abstract: | Based on the detailed analysis of various fault characteristics of asynchronous motor,this paper brings forward an integrated microcomputer protection scheme which has sequence components as the basic protection criteria,and integrates heat accumulation and diffusion model.In this paper,concrete implementation of the protection scheme is also expounded,especially for the heat overload protection.A protection device based on this scheme has already passed dynamic simulation experiments to prove its validity. |
