DEVICE CONTROLLING DISCONNECTOR Russian patent published in 1997 - IPC

FIELD: electrical engineering, high-voltage equipment. SUBSTANCE: coils of relays switching on and off disconnector are connected to power supply source via control key, coils of switching on and off starters are connected through contacts of these relays and auxiliary contacts of drive, armature windings and excitation windings of reversible electric motor and winding of stopping electromagnet are connected through contacts of starters to power supply source. Capacitor which discharge circuit is formed by diode and stopping electromagnet is connected through contacts of relays and starters, through charger with current-limiting resistor to power supply source. EFFECT: increased operational safety and reliability. 1 dwg
