330kVHGIS power distribution unit multi-direction wire outgoing structure and construction method

The invention relates to a 330kV HGIS power distribution unit multi-direction wire outgoing structure and a construction method. The multi-direction wire outgoing structure comprises 330kV HGIS equipment arranged in a C shape; the HGIS equipment is connected with two 330kV buses; and wire outgoing side voltage transformers and lightning arresters of two outgoing wires are arranged on two sides of the HGIS equipment according to a horizontal wire outgoing mode; an upper-layer wire outgoing vertical-direction wire hanging beam is supported and mounted through a horizontal-direction wire incoming and outgoing double-layer framework; an upper-layer wire outgoing horizontal-direction overline is mounted on the horizontal-direction wire incoming and outgoing double-layer framework; and an upper-layer wire outgoing vertical-direction overline is mounted on the upper-layer wire outgoing vertical-direction line hanging beam; if the upper-layer outgoing wire goes out in the horizontal direction, an upper-layer horizontal wire outgoing suspension string and a wire outgoing jumper wire are installed, and if the upper-layer outgoing wire goes out in the vertical direction, an upper-layer vertical wire outgoing suspension string, a wire outgoing jumper wire and a connecting line between the upper-layer wire outgoing vertical-direction overline and the upper-layer wire outgoing horizontal-direction overline are installed. According to the wire outgoing structure, the steel consumption and the occupied area are reduced.
