Model CZB1 Intelligent Protection Device is a new microcomputer protection product developed with advanced software and hardware, mainly suitable for 10 kV, 6 kV or 3.3 kV power distribution system with neutral point ungrounded or system with neutral point grounded by arc suppression coil. The device can provide monitoring and protection to high-voltage switch, and send electric parameters, running parameters, electricity information, running condition, failure information and recorded failure data of electric devices underground to the surface dispatching center in realtime, as well as receive command such as remote control, value setting, signal reset from the surface main station for remote operation.

Model CZB1 Intelligent Protection Device is special for high-voltage switch in mine underground, having special treatment for anti-vibration, anti-corrosion and anti-interference with good performance. It is installed in BGP or PBG series mine-used flameproof high-voltage switches and can replace traditional analog protector or computer protector with digital display, so it realizes update of existing distribution devices and also can be used as protector of new switches.

Model CZB1 Intelligent Protection Device has complete protection functions, exact action, high anti-interference. Its protection core employs DSP + CPLD design with realtime protection and exact protection delay; its high-speed memory with high reliability is used for storing protection value and action events of the protector; it also has failure test function for adjusting and testing in working field.
