[hunan Chuang'an Explosion-proof] Pjg-□/10(6)y Mine-used Flameproof and Intrinsically Safe Permanent Magnet High-voltage Vacuum Distribution Device
PJG-Opening/10(6)Y
Mine-used explosion-proof and intrinsically safe permanent magnet high-voltage vacuum power distribution device
Purpose and scope of use Application and range of application
This series of power distribution devices is suitable for mines containing explosive mixtures such as methane and coal dust. In an AC power supply system with a frequency of50Hz,a rated voltage of10KVor6KV,a rated current up to630A,and a three-phase neutral point ungrounded or not directly grounded, it can control and protect the power supply system and can be used for infrequently directly starting high-voltage motors.
Product features Product features
★It adopts a quick-opening door structure and a cart-type movement.
★Adopt a microcomputer integrated monitoring device with full Chinese display, which can display voltage, current, power, system operation information, etc. in real time.
★It has multiple protection functions such as overload, short circuit, leakage, insulation monitoring, overvoltage, undervoltage, etc.
★It is equipped with standardRS485andCANbus communication interfaces, and can also be optionally configured according to user requirements.
★It has thefunction of electricity metering.
★It isequipped with reliable mechanical interlocks, electrical interlocks, remote opening, emergency opening and other devices to ensure safety and reliability.
★The remote control adopts intrinsic safety control, and the intrinsic safety parameters are: voltage21.8V(AC),current78mA(AC).
★When configuredin the mine power automatic control and comprehensive monitoring system, it can realize the automation of the power distribution device, achieving the four remote functions of remote measurement, remote control, remote signaling, and remote adjustment, and realizing unattended substations, such as remote opening and closing, remote meter reading and other functions.
