Elementary analysis the Phase analysis In the application of Load six angle diagram

简要介绍了正弦交流电路、相量法的基本原理以及正弦交流量中复指数函数的几何意义,分析了负荷性质与电压和电流之间的相位关系,总结出继电保护中负荷六角图应用的一般原理.实践表明:掌握和运用相量分析法,通过设备启动投运时测量的负荷六角图,对分析和判断方向性保护的相别、相位关系以及保护方向的二次接线正确性具有一定的指导意义.

This paper briefly introduces the Sinusoidal alternating circuit, the Basic principle of Phase analysis and the geometric meaning of Sinusoidal AC flow of complex exponential function, and Analysis the phase relationship between load characteristics and voltage and current, Summarizing the general principles of Load six angle diagram applied in the relay protection, at the same time mastering and using Phase analysis. Through measuring Load six angle diagram when equipment start - up, It has the certain instruction significance when analyzing and judging phase relationship in the direction of phase protection and the Correctness of the orientations of the second wiring correctness.
