摘　　要：通过对一次三相电源插头内部特殊短路事故的现场复原和相关电器的测试,对插头绝缘材料、结构以及操作过程进行了分析,总结了短路产生的原因,提出了在电工技能训练中避免此类事故再次发生的措施.By duplicating the site where a internal short circuit occurred in a three-phase power plug, and testing the rele- vant electric appliances connected to the plug, a detailed analysis was made of the insulation material, structure and opera- tions of the plug. The cause of the short circuit was found out, and precautions, which should be taught in electrical skill trainings, were proposed to avoiding similar accident in the future.
