建议看看这个: http://learnelectricity.ausgrid. ... erator-to-home.aspx
After travelling through the transmission lines at very high voltage of 330 to 500 kV [1 kV = 1000V], transformers are then used to step-down the voltage, first in a large transmission substation to 33kV or 11kV, and then again closer to users in a zone or distribution substations. Another transformer on a power pole or in a big green box on the street, lowers the voltage to a much safer value to create the domestic supply voltage of 240V.
也就是把最高33kv的电压转到我们每家的240 影响量几乎可以忽略不记
但要影响你视线的话 可以考虑 |
