INTELLIGENT SWITCH-DISCONNECTOR Russian patent published in 2024 - IPC H01H33/666 

FIELD: electrical engineering.

SUBSTANCE: invention relates to high-voltage vacuum circuit breakers having disconnector function, and is intended for disconnection of electric current in circuit in order to protect power equipment of electric networks from short-circuit currents. Intelligent switch-disconnector comprises control and data transmission cabinet, at least one switch-disconnector module mounted on a frame having support insulators with contacts of the first and second current conductors, between which the switch-disconnector module is installed, wherein the switch-disconnector module is made in the form of a movable contact, which includes a vacuum arc-quenching chamber with a spring contact opening mechanism, which is placed in a protective insulating housing, fixed upper and hinged lower contacts, and also mechanism for manual switching on and off of vacuum arc-quenching chamber, including the vacuum arc-quenching chamber on/off lever, connected to the lever plate and the spring-loaded activation solenoid rod, mechanically connected to the vacuum arc-quenching chamber movable contact, as well as limit switches to determine the state of the vacuum arc-quenching chamber "on/off" and a limit switch of the "tilted" position.

EFFECT: increased reliability of disconnector operation and level of its electrical safety.
