高中《物理》第二册(必修加选修)中,关于远距离高压输电的原理是以单相输电为例研究的。教学时,常常利用如图1所示的高压线路输电模式:
In High School “Physics” Volume II (Compulsory plus optional), the principle of long-distance high-voltage power transmission is based on single-phase transmission as an example. In teaching, the high voltage line transmission mode shown in Figure 1 is often used:
