The HND-CK series switchgear intelligent control device has powerful functions and is used in various types of switchgear such as 3kV-35kV indoor switchgear, handcart cabinets, fixed cabinets, mid mounted cabinets, and ring main units. It has dynamic primary simulation diagram, high-voltage live display, circuit breaker opening and closing status indication, energy storage indication, grounding switch status indication, automatic heating and dehumidification data display and control, car position indication, opening and closing circuit integrity indication, human induction and cabinet lighting, voice error prevention prompt, and also has functions such as measuring voltage, current, active power, reactive power, active energy, reactive energy, power factor, frequency, and wireless contact temperature measurement. It can replace existing primary circuit simulation diagrams, live displays, automatic heating and dehumidification controllers, circuit breaker opening and closing buttons, etc. And it has RS485 communication interface, and the communication protocol is MODBUS communication protocol or other specified communication protocol (optional). Further intelligentize, digitize, and network the switchgear, making it convenient for users to use and operate.
