Flameproof and intrinsically safe high pressure vacuum AC soft starter QJGR-(50 ~ 400)/10


It is suitable for heavy load soft starting of three-phase AC high voltage motor with rated frequency 50Hz, rated voltage 10kV, 6kV, 3.3kV and rated current up to 400A in coal mine in explosive environment. It can meet the control requirements of different load objects such as pumps, fans, belt conveyors, scraper conveyors, air compressors, and feeders. It is a high-tech product integrating high-voltage vacuum electromagnetic starter, all-digital microcomputer speed regulation technology, and optical fiber isolation technology. The unique "S" curve makes the soft starting have the advantages of small starting current, adjustable starting speed balance, stable and reliable starting performance, and small impact on the power grid and institutional equipment. Connected with KJ series underground coal mine power grid monitoring system, it can realize remote automatic control, monitoring and monitoring of power equipment, and realize modern management such as unattended substation.
