Mining explosion-proof and intrinsically safe winch controller
Main application
QJZ-(80,120+30)/1140(660)M Mining explosion-proof and intrinsically safe winch controller .It is suitable for the mine with explosive gas (methane) and coal dust. In the circuit with AC 50Hz voltage of 660V or 1140V, it is a new intelligent winch combination switch which integrates the control of reversible winch, lighting and brake motor. The control mode is intrinsically safe remote control and local control of lighting signal.
Technical characteristics
The controller has the functions of monitoring and intelligent protection. The intelligent integrated protector takes the latest high-performance single chip microcomputer as the core. Through modular hardware design and unique software algorithm, it has strong anti-interference ability, reliable action and high sensitivity of protection. It has good human-computer interface, Chinese LCD display, menu operation, password authorization, query and modification, fault memory and other functions.
Protection function
With the multiple protection functions as short circuit, overload, leakage and open-phaset
