摘　　要：提出了电能质量敏感度测试系统的概念,对其组成、用途、功能进行了定义和描述;以交流接触器为例,建立了数学模型,并对其电能质量敏感度进行了仿真研究;用大功率电能质量信号发生装置与某型号的交流接触器构成电能质量敏感度测试系统,通过改变接触器线圈输入电压的跌落幅值和持续时间进行了大量的实验,得到了反映交流接触器对于电压跌落耐受能力的ITI曲线。仿真和试验所得结果可以为交流接触器在生产过程中的测试提供参考,并能推广到对其它用电设备进行电能质量敏感度测试。The concept,configuration,usage and function of the power quality susceptivity testing system are described. The mathematical model of AC contactor is built, and its power quality susceptivity have been carried through simulation research.Based on AC contactor＇s power quality susceptivity testing system, which is composed of power quality signal generator and AC contactor, many experiments hawe been done through changing the input voltage of AC contractor, and the ITI curve is gotten. Simulation and experiment results show that the mathematical model of AC contactor is correct; the testing system not only can fulfill its functions, but also can provide reference for AC contactor＇s design or manufacture and popularize to other equipments power quality susceptivity test.
