[摘 要]在传统的电工实验教学中,应用实际实验去模拟这些故障情况不仅成本过高,而且还存在一定的危险。为此,本文提出将仿真软件Multisim 11引入电工技术实验故障应用研究领域,借助其强大的整合能力,完成电工技术实验故障排查与分析工作。这样电工实验教学不仅会得到增强,而且还能有效地把握故障原因所在,并采取针对性措施予以解决。与此同时,仿真软件Multisim 11可以节省实验室建设成本,提高实验故障排查效率,扩展电工设备实验的故障和处理的范围和空间。

[Abstract]In traditional electrician experiment teaching, using real components to do fault experiment is not only expensive, but also has certain danger. Therefore, this paper proposes to introduce the simulation software Multisim 11 into the field of electrical technology experiment fault application research. With the help of its strong integration ability, the fault troubleshooting and analysis of electrical technology experiment can be completed. In this way, electrician experiment teaching will not only be enhanced, but also can effectively grasp the fault causes, and take targeted measures to solve. At the same time, the simulation software Multisim 11 can save the cost of laboratory construction, improve the efficiency of troubleshooting experimental faults, and expand the scope and space of electrical equipment experiment faults and processing.

电工实验教学要求对学生演示某个元器件出现开路、短路故障对电路产生的影响。这些现象可通过枯燥的定理、公式和框图进行解释,但是由于这些现象的出现往往会对电路中的相关元器件或仪器仪表造成损害,因而比较难用实际实验去模拟这些故障情况。同时,由于学生人数较多,从而出现了设备短缺的情况,抑或者对实验操作了解不到位,导致失误产生。因此,相关分析工作就变得非常重要,通过全面把握,确保电工实验可以顺利展开。采用Multisim11仿真实验,只需在计算机中改变电路中相应元器件的参数,就能模拟出有故障的电路工作情况。
