 摘      要

三相電路的工作情況不僅與三相電源有關(guān)，而且與三相負(fù)載的性質(zhì)和連接方式有關(guān)。三相電路的應(yīng)用在各個(gè)領(lǐng)域相當(dāng)廣泛，針對(duì)三相電路運(yùn)行狀況的實(shí)驗(yàn)就顯得非常重要而必須。然而實(shí)際的三相電路電壓較高，負(fù)載性質(zhì)多樣，因而針對(duì)三相電路的實(shí)驗(yàn)不僅危險(xiǎn)性較大，而且一些故障性試驗(yàn)較難進(jìn)行。電路仿真軟件Multisim提供了適用于三相電路仿真的各種元件模型及分析工具。該論文首先分別對(duì)對(duì)稱負(fù)載星形連接電路和三角形連接電路、不對(duì)稱負(fù)載星形連接電路和三角形連接電路進(jìn)行了理論研究，接著利用Multisim軟件進(jìn)行了仿真分析,并與理論分析結(jié)果進(jìn)行了比較。比較結(jié)果表明，仿真軟件具有快捷、方便，且效果理想的特點(diǎn)，利用Multisim軟件對(duì)三相電路進(jìn)行各種實(shí)驗(yàn)仿真分析，優(yōu)點(diǎn)明顯，適合在電工實(shí)驗(yàn)中推廣。

Abstract

the work of the three-phase circuit is not only related to the three-phase power, but also to the nature and connection of the three-phase circuit. Three-phase circuit applications is wide used in various fields, the experiments about the operation of the three-phase circuit are very important and inevitable. However, the actual three-phase high voltage circuit, the diverse nature of load, which for three-phase circuit test not only the risk of larger, but some of the fault to test more difficult.The circuit simulation software Multisim provides various component models and analysis tools for the three-phase circuit simulation, in this paper symmetrical triangle and star circuit connecting link circuit, asymmetric load star triangle connecting circuits and circuit were theoretical studied first, and then Multisim was used to analyze the simulation, and compared with the theory results. The results of this comparison showed that the simulation software was shortcut, convenient, and perfect, Multisim software is used for all kinds of the simulation analysis of the three-phase circuit, the advantages are very clear, it is propitious to generalize in electrical experiments.
