摘　　要：笔者从高精度陶瓷球的结构性概念出发,在随机分布的材料模型下,探索拉破坏强度准则。通过各项数据的综合推演,完全可以导出与经典弹塑性理论完全相同的强度准则。在电压等级日益增高的电力系统中高精度陶瓷球制作而成的电流互感器针对不同测试环境,感器精度和灵敏度的不同要求,对每种互感器存在的问题提出解决方案。Based on the structural concept of high precision ceramic ball,this paper probes into the principle of tensile failure under the random distributed material model.Through the comprehensive analysis of various data,it is possible to derive the exact same intensity criterion as classical elastoplastic theory.In rising voltage grade of power system,high precision ceramic ball made of current transformer for different test environment,sensor precision and sensitivity of different requirements,solutions are proposed for each transformer.
