针对传统的三相负载联接实验仪易于发生设备损坏和人身触电的现象，开发设计了基于三相心式变压器的负载联接实验仪。该实验仪运用心式降压变压器作为装置电源，能够有效地避免实验人员发生触电的危险。通过合理设计变压器的变比及负载，充分保证了不对称三相负载作星形联接时实验器材的安全。理论分析及现场对星形负载联接和三角形负载联接的实验数据验证了所设计实验仪器的合理性。

The traditional three-phase load experiment instrument is likely to cause damage of equipment and personal electric shock phenomenon, against which we designed the load experiment instrument based on three-phase core transformer. The experimental instrument uses core step-down transformer as device power so that it can effectively avoid the occurrence of the danger of electric shock. Rational design of the transformer ratio and load can fully guarantee the experimental equipment safety while taking the asymmetric three-phase load as the star connection. The data based on the theoretical analysis and site experiment with star load connection and triangle load connection have showed the rationality of the designed experimental apparatus.
