 摘      要

三相电路的工作情况不仅与三相电源有关，而且与三相负载的性质和连接方式有关。三相电路的应用在各个领域相当广泛，针对三相电路运行状况的实验就显得非常重要而必须。然而实际的三相电路电压较高，负载性质多样，因而针对三相电路的实验不仅危险性较大，而且一些故障性试验较难进行。电路仿真软件Multisim提供了适用于三相电路仿真的各种元件模型及分析工具。该范文首先分别对对称负载星形连接电路和三角形连接电路、不对称负载星形连接电路和三角形连接电路进行了理论研究，接着利用Multisim软件进行了仿真分析,并与理论分析结果进行了比较。比较结果表明，仿真软件具有快捷、方便，且效果理想的特点，利用Multisim软件对三相电路进行各种实验仿真分析，优点明显，适合在电工实验中推广。

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.
