| 摘 要： | GIS三相同壳母线VFT相电压测量的主要问题在于,每个电容传感器同时受三相电压的电场耦合。必须通过解耦,才能得到每相的电压值。本文对三相同壳母线三种主要结构形式下的电场耦合系数进行了分析,并且,根据数值计算结果,讨论了电容传感器的放置位置问题。

| Abstract: | The main problem in measuring VFT overvoltages on three phase enclosed GIS is that each capacitance sensor is coupled with the electric field of three phase voltages at the same time.In this paper,the coupling coefficients are analyzed on different structures of three phase enclosed GIS buses Then,according to the numerical calculation results,the positions of 3 sensors are discussed. |
