In this paper, the centre of electrode is suggested for heat conduction. Therefore, the specific reflow soldering process is needed. The comparison of temperature difference among the different areas of ZnO varistors is analyzed. With the nominal surge current, thermal behavior is analyzed. The operation point of temperature for disconnection is proposed. Accordingly, the thermal runaway-preventing ZnO varistors were covered with a fusible alloy, i.e., a thermal fuse, in the process of manufacture, which is expected to ensure there the liability of being resistant to lightning discharge and to ensure stability against thermal runaway in the failure mode. Additionally, it is expected to reduce much more limit voltage than the existing products to which the fuse was separately applied. The thermal runaway-preventing ZnO varistor of the surge protection devices can be widely used as part of the protection provisions of lightning discharge and surge protection demanded in connection with power IT about Green Growth which is nowadays becoming the buzzword in the electric power industry.
本文提出将电极中心用于热传导。因此，需要特定的回流焊接工艺。分析了氧化锌压敏电阻不同区域之间的温差比较。在标称浪涌电流下，对热行为进行了分析。提出了断开连接的温度工作点。因此，在制造过程中，防热失控氧化锌压敏电阻被一种易熔合金（即热熔丝）覆盖，这有望确保其耐雷电放电能力，并确保在故障模式下抗热失控的稳定性。此外，预计与单独应用保险丝的现有产品相比，它能降低更多的限制电压。浪涌保护装置中的防热失控氧化锌压敏电阻可广泛用作与绿色增长电力信息技术相关的雷电放电和浪涌保护保护措施的一部分，绿色增长如今已成为电力行业的热门词汇。
