Description

technical field

The utility model relates to a frame type, in particular to a frame type of an equilateral triangle power distribution device of composite insulating material.

Background technique

With the shortage of land for urban construction, more and more outdoor GIS are used to arrange substations in urban and suburban areas. In order to further reduce the area occupied by substations, the outgoing lines of power distribution devices mostly adopt regular triangle outgoing lines. However, the limitations of this scheme are as follows:

The triangular outgoing line and the two-way outgoing line share the first-line outgoing line structure, and the beam is long, which is inconvenient for on-site installation;

When the beam is installed, it is easy to damage the galvanized layer of the grounding part, thus affecting its service life;

In order to maintain a safe distance between the B-phase conductor and the upper and lower beams, the height of the outlet frame is increased, and the steel consumption is relatively large;

When the incoming line is 2-circuit single-circuit, there are four lightning protection lines entering the substation, and the structure only has 2 terminal posts, which cannot meet the requirements.
