日光灯电路参数测量实验中电路参数计算问题

Discussion on Curcuit Parameters Calculation in Electrical Engineering Experiment of Fluorescent Lamp Circuit

典型的日光灯电路参数测量实验中,根据实验数据,用两种不同的方法计算电路参数,算出的电路参数值相差较大。用Multisim仿真日光灯实验电路,理论数据与实验数据的对比表明,电路参数值之所以有很大差异,主要原因是把日光灯当成一个纯电阻所致。将日光灯近似为一个电阻和一个电感的串联,将能更好地模拟日光灯实际工作状态。

Based on the measurement data in the traditional electrical engineering experiment of fluorescent lamp circuit, the values of the circuit parameters calculated in two methods have a significant diffe-rence. After simulating the experimental circuit by Multisim, and comparing the experimental data with the simulation data, this difference was investigated and induced to the unreasonable circuit assumption that fluorescent lamp was a pure resistor. If the fluore-scent lamp was assumed to be a series induction and resistance cir-cuit, the simulation circuit would be a better approximation to the actual fluorescent lamp circuit with respect to the traditional assumption.
