Suitable for underground coal mines in explosive environments, high-voltage squirrel cage AC asynchronous motors with a rated frequency of 50Hz, rated voltage of 10kV, 6KV, and rated power below 2500kW are subjected to voltage reduction and current limiting starting. It has the advantages of low starting current, reduced impact on the power grid, and reliable starting performance. The technical parameters of the starting reactor are the same as those of the ordinary starting reactor, and there is a high-voltage vacuum contactor that shortens the reactor after starting. The contactor operation is automatically completed by the internal controller, without the need for additional control lines; Internally, we have taken the lead in adopting a fully Chinese and Chinese micro computer integrated controller, which not only has the ability to adjust time, current, and temperature values without opening the door, but also has the function of reactor temperature exceeding limit protection and reactor short circuit error protection (that is, when the high-voltage bypass contactor cannot be normally closed, it can automatically cut off the higher-level switch). Connected with KJ series underground power grid monitoring system, it can realize remote automatic control, monitoring and monitoring of power equipment, and realize modern management such as unattended Electrical substation.

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.
