摘　　要：金卤灯启动过程中的各种电参数(包括最低电压、再启动电压尖峰、再启动电压峰值、电压波形)[1]是反映灯的内在质量的主要依据。文章介绍了第二代金卤灯再启动特性测试系统中两项关键性的技术:1)灯电压信号的隔离传输,保证了灯电压测量的准确性;2)电流互感开关,提高了灯启动后最低灯电压测量的可靠性。Various electric characteristics in the restart process of MH lamp, including minimum voltage, re-ignition peak voltage, re-ignition voltage and voltage waveform, are the main attributs for internal quality of MH lamp. This paper introduces some pivotal techniques of the restart characteristics test system ： 1. Signal isolation for the transmission of lamp voltage, which ensures the accuracy of measuring the lamp voltage; 2. Mutual inductance switch, which improves the reliability of measuring the lamp minimum voltage.
