摘要：

This paper deal with the surge energy capability of ZnO-based varistors according to the Sb2O3 and Bi2O3. For the purpose of surge test for the class 1 grade. The direct lightning current (10/350 mu S) with high energy injected to the sample varistor. The thermal conductivity and the electrical properties, such as the nonlinear coefficient, leakage current, varistor voltage and dielectric constant were investigated. Among these, the thermal conductivity had a proportional correlation with the energy surge withstanding capability. Five ZnO varistors were prepared with varied compositions (the Bi/Sb ratio was set at 1/2), but the other processes that were conducted were the same, such as sintering, milling, and pressing. As a result, the energy capacity of the ZnO varistor was found to have a strong correlation with the microstructure. FESEM was used to observe the microstructure of the ZnO varistor.
