| 摘 要： | 迅速准确地查找小电流接地系统单相接地故障线路和故障点的位置，已有不同原理的选线定位保护应用于我国电力系统中。本文提出了“S注入法”选线定位新原理，基于该原理的TY系列选线定位保护已大量运行于国内电力系统，本文重点对该保护在实际应用中所遇到的电压互感器的接线方式进行了详细分析。这些接线方式除适合“S注入法”外，还具有消谐功能。

| Abstract: | In order to correctly indentify single phase to earth fault line and locate fault point as soon as possible,different protections based on different principles have been running in power system in our country.A new principle of a S's signal injection,which inject the signal through PT,is presented.A series of TY protections based on the principle have been put into action.This paper importantly analyzes the connection of a voltage transformer in practice.The type of connection has the function of eliminating harmonic wave,besides adapting to'the S's signal injection'. |
