| 摘 要： | 为了分析EAST装置电磁测量系统中70m双绞线给测量信号带来的影响，建立了电磁线圈和双绞线的等效电路模型。设计了有双绞线模型和没有双绞线模型的两种电路模型，并对这两种模型在simolorer6.0软件中进行了仿真，通过分析这两种模型的传递函数和仿真输出的电压峰峰值，证明了70m双绞线对EAST中电磁测量系统的影响是可以忽略的。

| Abstract: | In order to analyze the impact brought by the 70m twisted pair in the electromagnetic measurement system of the EAST tokamak, the equivalent circuit model of the electromagnetic coil and twisted pair was established, and circuit models with twisted pair and without twisted pair are designed, the these two circuit models are simulated with the simpolor6.0 software. By analyzing the transfer function of the two models and the voltage peak to peak of the simulation output, it is proved that the effect of the using the 70m twisted pair in the electromagnetic measurement system can be neglected. |
