摘    要:水阻器在水电站中遇到故障时作加载电阻;本文利用子面元法计算三相三极容器式水阻器中电流场的边值问题,通过静电比拟及镜像原理,将电流场问题转化为静电场问题.子面元考虑电荷实际分布情况进行分块,子面元上的电荷假设为线分布来求取电位系数,通过计算与试验结果比较,等效电导的相对误差在工程容许范围内,故此方法可供工程技术人员参考.

关 键 词:电流场  子面元法  电磁参数

Abstract:In hydraulic power plants, water resistors are often used as emergency loading resistance. This paper deals with the problem regarding the boundary-value solution of the current field in three-phase water resistors by the subarea method. Through electrical images and electrostatic analogy, the current field problem can be transformed into the solution of electrostatic field problem. The charge on the subarea is assumed as line distribution in analysis. The relevent formulas used for the container-type is derived. Through the comparison of numerical computation with industrial experimental results, its relative error is within the scope of engineering permission. Thus this method may be proposed as reference for the designers.
Keywords:current fields  subarea method  electromagnetic parameters
