摘要
Abstract
Based on the analysis of the current inverse-time characteristic model and the heat accumulation model, a thermal overload protection device is presented considering the low voltage motor thermal overload protection. The overall structure, hardware design and protection algorithm are analyzed, and the results of testing and inspection are given. The experiments show that the protection device has higher detection accuracy, thus it is able to fully meet the low voltage motor thermal overload protection needs.关键词
