变电站biàndiànzhàn改变电压的场所。为了把发电厂发出来的电能输送到较远的地方,必须把电压升高,变为高压电,到用户附近再按需要把电压降低。这种升降电压的工作靠变电站来完成。变电站的主要设备是开关和变压器。按规模大小不同,称为变电所、配电室等。{transformer substation; place for changing the voltage of power grid. In order to transmit electricity to remote areas, the voltage must be increased to produce high-voltage electricity, but reduced to allow a particular piece of equipment to be used. All this is done at transformer substations. The major types of equipment in these substations are switches and transformers, referred to as transformer offices or distributing rooms according to their size.} |
