摘　　要：小型断路器接线端子的温度,是实际运行中判断小型断路器电气安全和火灾隐患的重要依据。通过小型断路器在不同负载率下接线端子温度数据的实际测试,分析了不同情况下根据低负载率下接线端子温度数据计算高负载率下接线端子温度数据时的误差大小,获得了一些重要结论。The temperature of MCCB terminal is the important basis for determining electrical safety and fire hidden troubles of MCCB during the actual operation. The temperature of MCCB terminals is tested at different load rate, temperature errors of terminal at high load rate calculated as per the temperature data of terminals at low load rate based on different cases are analyzed, and some important conclusions are obtained.
