摘要

本文采用5脉冲电流对ZnO压敏电阻进行冲击实验。研究了不同类型压敏电阻的抗冲击性和表面温升特性，探讨了多脉冲电流加热对压敏电阻老化的影响。利用实验数据，分析了ZnO压敏电阻的冲击寿命分布和损伤模式。压敏电阻的类型对抗冲击性有很大的影响，这与内部均匀性密切相关。ZnO压敏电阻的不均匀性会影响其能量吸收能力。压敏电阻的不均匀性越差，吸收能量的能力就越差，抗冲击能力也就越差。

Study on the Influence of Thermal Effect of Multi-Pulse Lightning Current on the Aging Characteristics of ZnO Varistor

In this paper, a 5-pulse current is used to conduct an impact experiment on ZnO varistor. The impact resistance and surface temperature rise characteristics of different types of varistors are studied to explore the influence of multi-pulse current heating on the aging of varistors. Using experimental data, the impact life distribution and damage patterns of ZnO varistors are analyzed. Varistor types have a great influence on impact resistance, which are closely related to internal uniformity. The non-uniformity of the ZnO varistor will affect the energy absorption capacity. The worse the non-uniformity of the varistor, the worse the ability to absorb energy, and the worse the impact resistance.
