The potential distribution on the water face of the open-type three-phase six-electrode water resistors

水电站中新机运行时,三相六极开放式水阻器常用作电气负载。为了防止事故发生,确定水面安全区域,必须计算水面的电位分布;文献[1,2]分别叙明用子面元近似数值法分析和计算三相三极水阻器中的电流场。首先,本文在此基础上推出三相六极水阻器水面电位的计算公式,通过模拟试验装置,电位计算结果与测试结果相当吻合,说明计算方法正确,实际可行;其次,将所编程序用于三相六极开放式水阻器实例,求出水面电位分布曲线,供工程人员参考。

For determing the safety region, the potential distribution on the water face of the open-type three-phase six-electrode Water Resistors is calculated by subarea method Firstly, through the comparison of numerical calculation with experimental results for container-type water resistors; the method is proved to be fairly accurate. Secondly, as a practical example, the pontential distribution on the water face along the line connecting two electrod center for the open-type 3-phase 6-electrcd water resistors is given. The ccmputor program may be proposed as a reference for engineers.
