The paper offers and analyzes a new complex solution – open switchgear with polyhedron circuit topology, with novel circuit and arrangement approaches including new electrical equipment. Decreasing numbers of disconnectors, better structural characteristics, elimination of vulnerabilities such as sections and busbar systems are the key characteristics of this solution. Due to a new circuit topology and equipment components, the open switchgear on the whole becomes more reliable, flexible, and less costly. Examples of arrangement solutions are given. We study the data on the 220 kB switchgear component outages in one of the largest regions of Russia in the period from 2018 to 2020. The use of SF6 circuit-breakers decreases the frequency of occurrence and time of the switchgear component outages in power grids. However, it is reasonable to use transfer-busbar circuits or double-breaker circuits.
