Support Structures for Seal Switches Located Near Bus Lines

Abstract

The authors propose three designs for seal switch support structures located near power plant bus lines. The first one has a plate that is attached to bus lines located in the same plane. The second uses a support insulator as the case and can be attached to several bus lines at the same time or each of them individually to provide a wide application range. The third design stipulates seal switch installation on overhead line pylons. The authors provide detailed descriptions of the designs and explain how the trip settings are adjusted on them.
