对日光灯管的电路模型的定性分析
|
摘要
对日光灯管的电路模型的探讨是教学中很好的拓展课题,然而多篇文献给出了不同的结果,为此,本文依据常规课堂实验数据,通过对电感线圈镇流器型日光灯电路的分析,探讨了日光灯管的电路模型的构建,结果表明正常工作状态的灯管的负载属性应该为电感性,可以近似认为纯电阻性。同时,依据经典电磁学理论对灯管的工作机理进行了定性分析,所得结果与实验描述一致,并对其他文献中误判为电容性的原因给出了解释。
Although the circuit model of the fluorescent tube is studied in many articles as a topic in teaching,different descriptions are reported and a dilemma is come forth.Therefore,in this paper,the results of a routine classroom experiment are analyzed,and demonstrate that the fluorescent tube in normal working state should be treated as an inductance,and also could be approximated as a resistor.Meanwhile,the discussion of the working mechanism of the fluorescent tube according to the classical electromagnetism theory,is consistent with the experimental results,and explains the reason for misjudging the tube as a capacitor in some literatures.
