一种电工实验电路的分析

Analysis of A Kind of Experimental Circuit of Electrical Engineering

以日光灯电路的工作原理为例,分析了当电源电压降低时灯管两端的电压反而升高的原因,认为其特性与气体放电伏安特性的弧光放电过渡区非常相符,而电源电压对灯管启动时工作的影响则由灯管内蒸气中含有的汞原子的量所决定.

This paper illustrates the working principle of fluorescent lamp circuit and analyzes the reasons that the voltage between the two ends of lamp tube will increase while the supply voltage decreases. The property is in accordance with voh-ampere characteristic of gas discharge in discharge transition region of arc light. However, the effect on the start of lamp tube from supply voltage depends on the quantity of Hg-atom that stream contains in the tube.
