The mining explosion-proof frequency converter is a power control device designed for coal mines with explosive hazardous environments such as coal dust and gas. It is used to adjust the speed and output power of AC motors. It is suitable for asynchronous motors and permanent magnet synchronous motors. It has the characteristics of large starting torque, high speed regulation accuracy, long power supply distance, energy saving and high efficiency, safety and reliability.

1. Features
● Using advanced SVPWM space vector PWM modulation control, the output torque is large,150% of the  rated torque can be reached at 0.5Hz, and the maximum torque output can reach 220%.
● The frequency converter adopts a three-level inverter topology, with small input and output  harmonics, meeting the requirements of EMC standards; the built-in output filter unit reduces the motor insulation stress,and the output cable can be up to 3000 meters long.
● Excellent over-current suppression and over-voltage suppression functions to avoid frequent failures  and meet the requirements of complex working conditions.
● The builtin insulation monitoring system can monitor the insulation status between the inverter and the motor in real time to achieve effective leakage protection.
● Adaptive power balancing function can provide precise load distribution control,and the power imbalance is less than 2%.
● Built-in PID regulator can match various sensors to form closed-loop control
● Full Chinese display interface,matrix keyboard operation,intrinsically safe design,safe and reliable
● External intrinsically safe Ethernet port to facilitate program debugging and data transmission
● Meet the communication requirements of smart mines and have standard communication interfaces
★ Multi-parameter data collection: The equipment is capable of real-time collection of more than 80 electrical parameters such as voltage,current,power and harmonic data; it cooperates with the industrial big data platform to automatically generate historical trend curves such as current, voltage and power of  load equipment; according to different regions, Comparative analysis of energy consumption in different periods to achieve accurate energy consumption management
★ Predictive maintenance of equipment: Based on the analysis of various electrical parameters of the load equipment, the industrial big data platform is used to build an equipment failure prediction model, and the operating status of the equipment and the priority of equipment maintenance are analyzed in a timely manner to realize the predictive maintenance function of the load equipment.
★ Multiple communication interface support: 485 interface, Ethernet interface, wifi, 5G, 4G and other communication interfaces; supports Modbus, MQTT, HTTP, IEC-60870 and other communication  protocols.
