SMRC |
SMRC is 3 phase, SF6 gas insulation, vacuum interruption auto circuit recloser designed for pole mounted or substation applications for up to 27kV, 630A power distribution system.
- SCADA-mate configuration, or 3 current transformers and 6 resistive voltage sensors are integrated inside of the tank
- World first resistive voltage sensors with an accuracy of below 0.5%
- Field proven vacuum Interrupter to ensure safe and long lifetime
- SF6 Gas insulation media enclosed in Stainless Steel tank
- Solenoid and dual latch mechanism: opening time less than 25ms; clearing time less than 2.7 cycles; mechanical trip free; anti-pumping characteristics
- Horizontally installed bushings to the tank showing superior insulating capability and strong short circuit characteristics compared with vertical type bushings
- Micro-processor-based controls including RTU function, fault recording, contact wear monitoring, electrical quantity metering and event reporting
- Electrical Emergency Close/Open device to cope with relay's failure
- Dead line operation module consisting of battery power, DC/DC converter and capacitor, low voltage closing coil solenoid in the control unit to deal with the line outage (optional item)
