ELECTRIC VEHICLE CHARGING STATION FOR CONNECTING TO HIGH OR EXTRA HIGH VOLTAGE TRANSMISSION LINE AND OPERATION METHOD THEREOF

摘要

An electric vehicle charging station for connecting to a span of a high or extra high voltage transmission line, comprising: a tap for connecting to the span of the transmission line; a substation comprising one or more power voltage transformers; a plurality of electric vehicle chargers. The power voltage transformers are station service voltage transformers, auxiliary service voltage transformers, or power VTs. Said power voltage transformers may be star-delta transformers or star-star transformers. Said tap may comprises, for each phase of the transmission line: an insulator for linking a first and a second interrupted conductor points of an interrupted transmission line conductor; a drop conductor connected between the first interrupted conductor point and said substation; a shunt connector connected between the second interrupted conductor point and a point of the drop conductor or connected between the first and second interrupted conductor points.
