摘要

本文研究了三相气体绝缘开关设备的电场矢量特性。分析了一个简化GIS模型三相施工过程中的电场。结果表明，电场矢量随外加电压的相位变化。当电压相位在一个周期内变化时，电场矢量发生变化并连续旋转。在三相GIS中不存在零电场。在导体和外壳之间的区域，电场矢量轨迹几乎是线性的，类似于单相结构;而导体之间的电流则有变化:线性、椭圆形、圆形。结果与单相GIS中的电场矢量进行了比较。

Locus and pattern of electric field vector in the insulation of three-phase gas insulated switchgear

This paper deals with electric field vector characteristics in three-phase gas insulated switchgear (GIS). The electric field in a three-phase construction of a simplified GIS model was analyzed. The results show that the electric field vector varies with phase of applied voltage. While the voltage phase varies in a cycle, the electric field vector changes and rotates continuously. There is no zero electric field in three-phase GIS. The electric field vector locus in the region between conductor and the enclosure is almost linear, resembling a single-phase construction; while ones between conductors have variations: linear, elliptic, circular. The results are compared with the electric field vector in single-phase GIS.
