电影机放映氙灯冲击电流的控制

To Control Rush Current of Projecting Xenon Lamp of a Film Projector

围绕氙灯的构造及其工作原理就冲击电流对氙灯损害进行讨论，针对当前ＷＬＣ系列和ＧＦＡ系 列等整流器产品，普遍对冲击电流没有控制或控制不佳所造成的对氙灯的损害，提出对ＧＦＡ０２ －１５０／３５型整流器原磁饱和电抗器回路增力。一延时继电器Ｊｔ和一个 ３０Ω５０Ｗ的电阻Ｒ_(２０)后使冲

This article describes that rush current does harm to xenon lamp from its structure and working principal. As the present WLC and GFA series rectifiers have no or incomplete control over rush current which does harm to xenon lamp, the author presents that a timing delay it and a 30 Ohm and 50 Watt R_(20) are added to the bubble and reactor circuit of GFA02-150/35 type rectifier so that the problem can be solved.
