Mine Explosion-Proof and Intrinsically Safe Permanent Magnet Mechanism High-Voltage Vacuum Power Distribution Device

This series of products uses the WTG-200 high-voltage switch microcomputer integrated protection device as the control and protection system of the equipment, with short circuit, overload, leakage, insulation monitoring, overvoltage, undervoltage protection, and anti-overstepping protection functions. The front door panel is equipped with a human-machine control window, through which you can see the operating status, insulation status, three-phase voltage, load current, electricity, clock and other real-time operating parameters of the equipment. The front door buttons can realize the equipment function settings and parameter adjustment. This series of products has stable performance, sensitive and reliable action.

2. Technical advantages and features

• WTG-200 high-voltage switch microcomputer comprehensive protection device uses a high-performance microprocessor as the core of protection and monitoring. It has powerful data  processing capabilities, fast computing speed, and stable and reliable operation;
• The human-computer interactioninterface uses a Chinese LCD screen, which can intuitively and clearly  reflect the current system protection parameters and equipment operating status,and is very convenient to operate;
• It has standard RS485 and CAN communication interfaces, provides communication protocols, and has  four network remote functions of "remote signaling, telemetry, remote adjustment, and remote control", which can realize remote monitoring and control of substation equipment;
• Real-time display of equipment fault status, and equipped with fault recording function and fault memory function. Detailed fault records can be queried to provide assistance for equipment maintenance;
• It has front door simulated leakage test function;
• Time-based electricity metering and remote meter reading functions during peak and flat valley periods; 7. The protection function can choose to put in or close;
• It has the function of fine-tuning calibration of measurement parameter errors; 9.Can realize current anti-overstep protection function;
• You can choose the voltage loss delay trip function to avoid large-area power outages when the mine power grid loses voltage instantly due to faults or lightning strikes.
