摘　　要：针对温度保险丝与ZnO压敏电阻在串联使用中的性能问题,通过对温度保险丝与ZnO压敏电阻热保护配合工作原理的理论分析,利用(8/20μs)雷电冲击平台及热稳定测试装置分别将温度保险丝以及温度保险丝与ZnO压敏电阻串联后进行实验,并将实验数据进行分析,得出温度保险丝与ZnO压敏电阻进行热保护配合时的冲击耐受能力大于温度保险丝单独使用时的情况,而器件整体的残压会相应的增加的结论;在热稳定试验中,不同型号的温度保险丝和ZnO压敏电阻进行热保护配合时,在固定电流的作用下,器件的表面温度随时间变化的曲线呈现出不同规律。在温度保险丝与ZnO压敏电阻配合使用的实际应用中具有一定的参考价值和意义。In order to research the performance of the thermal fuse in series with Zn0 Varsitor. Based on the theoretical analysis on operational principle of thermal fuse and ZnO Varistor, thermal fuse and ZnO varistor are put in series and taken into the experiments which employ the （8/20 p.s）lightning impulse generator and thermal stability testing device respectively. By analyzing the experimental data, it is proposed that the impact resistant ability of a single thermal fuse is far more inferior to thermal fuse in series with Zn0 varistor, but the residual voltage of two devices in series increases correspondently; in the experiments of thermal stability, under the some current, the curve of surface temperature versus time in different coordination types takes on different trends, which has a reference value in the practical coordination between thermal fuse and ZnO varistor in series.
