Experimental device and experimental method for exploring relationship between wire harmonic resistance and harmonic order

The invention provides an experimental device and an experimental method for exploring the relationship between wire harmonic resistance and a harmonic order, which are applicable to copper wires, aluminum wires and various types of stranded wires. The experimental device comprises a programmable control power supply, a to-be-tested wire, a high-precision power quality analyzer, an infrared thermometer and an RLC load cabinet. The experimental method can accurately measure the surface temperature of the to-be-tested wire, the active power at the first end and the tail end and the magnitude ofthe current flowing through the wire, the wire harmonic resistance is thus obtained and is compared with the harmonic order, and thus, the relationship between the wire harmonic resistance and the harmonic order is obtained. 本发明提供了种探究导线谐波电阻与谐波次数关系的实验装置及实验方法。本发明提供的实验装置及实验方法适用于铜线、铝线及各种型号的绞线，其中实验装置包括可编程控制电源，待测导线，高精度电能质量分析仪、红外测温仪及RLC负载柜。本发明的实验方法可对待测导线表面温度、首末端有功功率及流经导线电流的大小进行准确测量，并据此得出导线谐波电阻，并和谐波次数进行比较进而得出导线谐波电阻与谐波次数的关系。
