资料介绍

为解决输配电系统检测设备供电难题,设计了能够从输电线路架空地线取电系统电源电路。根据输电线路地线感应电压不稳定的特点,采用不可控整流桥和单端正激变换电路,结合闭环控制技术,设计并搭建了电路模型。通过分析在不同输入电压情况下电路的输出特性,验证了电路可行性,该电源电路实现了将9V~100V可变交流输入转换为12V稳定直流输出,并且通过拟合不同负载情况下电路输出功率特性曲线,分析得出电源电路输出功率稳定。

In order to solve the power supply problem of Transmission and transformation system testing equipment,a power supply circuit of getting electricity from overhead grounding line system for transmission lines is designed.According to the characteristics of the induced voltage instability of transmission lines,combined closed loop control technology,uncontrollable rectifier bridge and single ended forward conversion circuit are adopted.The power circuit model is designed and built.The feasibility of the circuit is verified by analyzing the output characteristics of the circuits under different input voltages.The power circuit realizes the conversion of 9 V~100 V variable AC input to 12 V stable DC output.The output power of the circuit is stable,by fitting the output characteristic curve of the circuit under different load conditions.
