Mining explosion-proof and intrinsically safe lighting integrated protection device
Application:
ZJZ2-4.0/1140(660)M Mining explosion-proof and intrinsically safe lighting integrated protection device.It is suitable for coal dust and explosive gas (methane) underground coal mine. It can control the power supply of 127V level lighting signal equipment, and the power supply is introduced as 50 Hz 1140 V or 660 V.
The device has the functions of microcomputer monitoring and intelligent protection. The intelligent integrated protector takes high-performance single chip microcomputer as the core, adopts military grade peripheral chips and high-performance precision converter. Through modular hardware design and unique software algorithm, it has strong anti-interference ability, reliable action and high sensitivity of protection. It has good man-machine interaction interface, Chinese LCD display, menu operation, password authorization, anti misoperation, query and modification, fault memory and other functions. It has RS485 communication function, which is convenient for docking and monitoring with other automation equipment.
Technical advantages and functional features:
1.Quick door openning structure:
2.It can voltage conversion,no need to pull out the dry transformer change;
3.With short circuit,leakage,leakage blocking protection function and insulation monitoring function.
