Abstract: At present, the ecological environment is improving day by day and the activity of birds in substations increased significantly, so the gate-type frame of substation structure has become the hardest hit area for birds to bulid their nests. If the gate-type frame of substation structure has a bird-related faults, it is very easy to cause a power outage in the entire busbar, causing major economic losses and impacts on the people's livelihood. The installation starts at the source of the nesting space for birds, significantly reduces the proportion of nesting space for birds on gate-type frame of substation structure, which provides a guarantee for the stable operation of the equipment in the station.
