对自镇流荧光灯的灯电流波峰系数进行补充检测是有益的。至于如何测量值得讨论与研究。直接引用“管形荧光灯交流电子镇流器”国标中规定的检测方法是不合理的 ,且会影响灯的工作参数。经试验 ,提出采用磁感应传感器作电流采样的方法 ,来测量自镇流荧光灯的电流波形 ,进而检测波峰系数是合理、有效的。最后给出制作这种感应传感器的具体方法与检测自镇流荧光灯的波峰系数的5种方案。
It is beneficial to supplement the lamp current crest factor of a self-ballasted fluorescent lamp. As for how to measure it is worth discussing and researching. Direct reference “tube fluorescent AC electronic ballasts” GB test method is not reasonable, and will affect the lamp operating parameters. After testing, it is reasonable and effective to measure the current waveform of the self-ballasted fluorescent lamp by using the magnetic induction sensor as the current sampling method. Finally, five methods of making this kind of inductive sensor and detecting the crest factor of self-ballasted fluorescent lamp are given.
