SWITCH-DISCONNECTOR Russian patent published in 2024 - IPC H01H1/00 

FIELD: electric power industry; electrical engineering.

SUBSTANCE: invention relates to the field of electric power engineering and electrical engineering, in particular to switch-disconnectors, which are intended for switching of electric circuits. Switch-disconnector consists of a housing, inside which a first fixed contact, a second fixed contact and a movable contact are installed, which performs electrical connection between the first fixed contact and the second fixed contact, wherein the movable contact is coupled with a shaft-crossarm by means of brackets fitted on movable contact axes to allow rotation of said movable contact relative to axis of rotation of the shaft-crossarm.

EFFECT: increased area of contact of movable and fixed contacts, at the same time heating of the switch-disconnector is reduced, reliability of the switch-disconnector is increased, the design of the switch-disconnector is simplified.
