一种特高压输电系统用大通流容量、低残压压敏陶瓷制备方法
摘要：
一种特高压输电系统用大通流容量、低残压压敏陶瓷制备方法，制备原料包括氧化锌ZnO、氧化铋Bi2O3、三氧化二锑Sb2O3、二氧化锰MnO2、氧化铬Cr2O3、三氧化二钴Co2O3、二氧化硅SiO2、氧化银Ag2O、Ga(NO3)3、硝酸铝Al(NO3)3。其有益效果是：泄漏电流得到抑制；Al和Ga元素的共同添加使得本配方制作的ZnO压敏电阻的老化性能更加稳定，消除了单纯添加Ag离子带来的压敏电阻老化性能不稳定的不足之处。
摘要（英）：

The invention provides a preparation method of large-discharge-current-capacity and low-residual-voltage voltage-sensitive ceramic used for an ultrahigh voltage power transmission system. The ceramic is prepared from zinc oxide ZnO, bismuth oxide Bi2O3, antimonous oxide Sb2O3, manganese dioxide MnO2, chromic oxide Cr2O3, cobalt oxide Co2O3, silicon dioxide SiO2, silver oxide Ag2O, Ga(NO3)3 and aluminium nitrate Al(NO3)3. The method has the advantages that the leakage current is restrained, the ageing performance of a ZnO voltage-sensitive resistor manufactured according to the formula is more stable by adding elements Al and Ga together, and the defect that when only Ag ions are added, the ageing performance of the voltage-sensitive resistor is not stable is overcome.
