220kV power distribution unit outgoing line structure

Disclosed is a 220kV power distribution unit outgoing line structure. The 220kV power distribution unit outgoing line structure comprises an outgoing line side isolation switch connected with a power distribution unit, and a voltage transformer and a lightning arrester are both connected to an output line of the outgoing line side isolation switch; and the voltage transformer and the outgoing line side isolation switch are arranged on the same prop. The distance from the outgoing line side isolation switch to an enclosure wall is 7 meters. According to the 220kV power distribution unit outgoing line structure adopting the technical scheme, the voltage transformer is arranged on the prop of the outgoing line isolation switch to form combined equipment; and, in the arrangement manner, the distance from the outgoing line side isolation switch to the enclosure wall is shortened to be 7 meters, and the longitudinal dimension is effectively reduced. The technology has a wide application prospect and can be used in all open type transformer stations; and, if the technology is further popularized, land occupied areas of the transformer stations are further reduced, and the land resource is saved.
