摘要
目的增强太阳模拟器氙灯驱动运行的可靠性,给太阳模拟器研制提供技术保障,针对太阳模拟器大功率短弧氙灯放电特性进行试验研究。方法设计太阳模拟器的大功率短弧氙灯放电特性测试方法,然后通过理论计算和实际测试验证氙灯电源初始电流对短弧氙灯放电特性的影响,并采用增设优化电路的方法对其放电特性进行改善。结果在初始电流为70 A和120 A两种情况下,弧光放电电流到达谷值以后的电流稳定度分别为1.8616和0.9867,增设优化电路后,再次进行短弧氙灯放电特性测量,将初始电流降低到60 A,而稳定度可达到0.5409。结论改善后的电路基本可实现短弧氙灯放电理想状态,完成了对短弧氙灯进入电流击穿阶段后形成的稳定弧光放电电流特性的优化,大大提升了氙灯点灯成功率,为增强太阳模拟器可靠性提供了试验支持。
The work aims to enhance the driving operation reliability of xenon lamp for solar simulator,provide technical support for the development of solar simulator,and study the discharge characteristics of high power short arc xenon lamp for solar simulator.First,test method for discharge characteristics of high-power short arc xenon lamp for solar simulator was designed.Then through the theoretical calculation and practical tests,the influence of the initial current on the discharge characteristics of short arc xenon lamp was verified,and additional optimized circuit for short arc xenon lamp was adopted to improve discharge characteristics.Under the initial current of 70 A and 120 A,the current stability after the arc discharge current reached the current valley was respectively 1.8616 and 0.9867.After the addition of optimized circuit,the discharge characteristics of short arc xenon lamp were measured again,the initial current was reduced to 60 A and the stability was up to 0.5409.The improved circuit can basically achieve the ideal discharge state of short arc xenon lamp.It completes the optimization of the stable arc discharge current characteristic after the xenon lamp enters the current breakdown stage,greatly enhances the success igni-tion rate of xenon lamp,and provides experimental support for improving the reliability of solar simulator.
