FACTORY-ASSEMBLED SWITCH GEAR Russian patent published in 2002 - IPC

FIELD: supply and distribution of electric energy for electric power supply, control and protection of essential services. SUBSTANCE: factory-assembled switch gear comes in the form of conjugate panels with interconnected collecting buses. Each commutation automatic switch is fitted with separately operating release device for remote disconnection and with separately operating coil for remote control over electric motors. System controlling commutation automatic switches is equipped with telemechanics system and incorporates units of telecontrol and telewarning brought outside of operator's telemechanics. It ensures remote control over switching on and off and over indication of positions of commutation switches, it includes device of protective disconnection operated by microprocessor protection relay. Protection relay provides for change of relay protection and settings. EFFECT: expanded functional capabilities, increased operational qualities, reliability and safety. 3 cl, 1 dwg
