500kV indoor GIS double-layer outgoing line structure with lightning arrester arranged at high position

Abstract

The utility model relates to a 500kV indoor GIS double-layer outgoing line structure with lightning arresters arranged at high positions, which comprises an upper-layer framework, a lower-layer framework, a second three-phase lightning arrester arranged on the upper-layer framework, a second three-phase lightning arrester arranged on the lower-layer framework, a third three-phase lightning arrester arranged on the lower-layer framework, a third three-phase lightning arrester arranged on the lower-layer framework, and a fourth three-phase lightning arrester arranged on the lower-layer framework, the three-phase wire outlet loop is connected with a three-phase wire outlet loop on the upper- The three-phase wires are arranged on the upper-layer framework and the lower-layer framework, the three-phase wires on the upper-layer framework and the three-phase wires on the lower-layer framework are the same, and the phase distances between the three-phase wires are equal. Under the condition of the same outgoing line interval, the double number of outgoing line loops is achieved, the occupied area and the investment amount can be reduced for a new project, and the project requirements of multiple outgoing line loops can be met for an extension project on the basis of the limited reserved outgoing line interval.
