1 高压钠灯等效电路高压钠灯发光体是汞和钠 ,与镇流器、触发器组成工作电路。电路中电源、镇流器、灯 (含触发器 )三者之间不满足直角三角形关系。实测发现灯电压超前灯电流 ,灯也呈感性 ,其等效电路见图 1。有文章[1] 提出三者之间电压、阻抗分配模型为 :Ｕ2 =Ｕ2Ｌ +ＸＵ2?
A high-pressure sodium lamp equivalent circuit High-pressure sodium lamp light mercury and sodium, and ballast, trigger circuit composed of work. Circuit power, ballast, lamp (including flip-flop) between the three does not meet the right triangle relationship. The measured lamp voltage led light current, the lamp is also sensual, the equivalent circuit shown in Figure 1. Article [1] proposed the voltage between the three impedance distribution model: U2 = U2L + XU2?
