煤炭科学研究总院合肥研究所和兖州矿业(集团)公司济宁二号煤矿提出了电机保护新的基础技术理论,并在此基础上找到电机保护新方法,即通过在线测量运行电机绕组直流电阻来确定电机实际温升,并与最高允许温度下绕组电
Hefei Institute of Coal Science and Research Institute and Yanzhou Mining (Group) Company Jining No.2 coal mine proposed a new basic theory of motor protection, and on this basis to find a new method of motor protection, that is, through the on-line measurement of motor winding DC resistance Determine the actual motor temperature rise, and the maximum allowable temperature winding power
