    • A ZnO surge arrester for high-temperature operation is characterized in that a grain boundary layer between ZnO grains thereof contains a BaTiO3-based positive temperature coefficient thermistor material, which takes 10-85 mol % in the overall grain boundary layer, and when operating temperature raises, the positive temperature coefficient thermistor material in the grain boundary layer has its resistance sharply increasing with the raising temperature, so as to compensate or partially compensate decrease in resistance of components in the grain boundary layer caused by the raising temperature, thereby making the resistance of the grain boundary layer in the ZnO surge arrester more independent of temperature. The ZnO surge arrester thus is suitable for operation where a maximum operating temperature is higher than 125° C., or even higher than 150° C.
    • 用于高温操作的ZnO避雷器的特征在于,其ZnO晶粒之间的晶界层包含基于BaTiO 3的正温度系数热敏电阻材料,其在整个晶界层中占据10-85mol%,并且当工作温度 升温时,晶界层中的正温度系数热敏电阻材料的电阻随着升温而急剧上升,从而补偿或部分补偿由升温引起的晶界层中的组分的电阻降低,从而使电阻 的ZnO避雷器中的晶界层更加独立于温度。 因此,ZnO避雷器适用于最高工作温度高于125℃或甚至高于150℃的操作。
