MULTIPURPOSE POWER SUPPLY SYSTEM FOR LINE LOADS

FIELD: power engineering; power supply to line loads and its distribution among. ^ SUBSTANCE: proposed system has line load power supply unit fed from power transmission line and built of four compartments accommodating power transmission lines, as well as distribution bus with switching devices and telemechanics system. Multipurpose power supply system for line lodes has main and stand-by power supply channels, their automatic turn-on devices, as well as no-break power supply incorporating unattended storage battery and inverter and used to supply with power low-voltage no-break power supply panel. Connected to no-break power supply panel are line loads that need no-break power supply. Load power supply unit is connected to power transmission line along its route by means of two taps and two overhead lead-ins equipped with bushing insulators. Cable module disposed under power supply unit is used to bring power and check cables out to cable networks of line load. ^ EFFECT: enlarged functional capabilities, enhanced reliability, performance characteristics, and safety in operation. ^ 8 cl, 5 dwg
