小电流接地系统单相接地电容电流补偿与选线双功能装置的研究

The Reasearch about both Function Device of Compensate and Line Selection about Single-Phase Grounding Capacitire Current for Small Current Grounding System

在理论分析的基础上 ,阐述了中性点经消弧线圈接地电网的单相接地电容电流检测和补偿的原理 ,解决了补偿与选线之间的矛盾 ,并研制出补偿与选线双功能动态模型装置 ,试验结果与理论分析相符合。

Based on the principle analyzing, the single phase grounding capacitive current examination and compensation principle of a electric network whose neutral point connects to the ground via arc suppression coil is introduced, which solves the contradiction between compensation and line selection. A whole dynamic model device about compensation and line selection is developed. The experiment result is consistent with theoretic anaysis.
