Product Description
1. Function

Variable frequency inverter is used in underground mines with explosive gas (methane) and coal dust. Main spare partsSuch as IGBT, filter capacitor, control core adopt imported brands to ensure reliable longtime
Operation. This series adopt vector control technique with perfect motor protection
And good speed adjusting to realize soft start and soft stop of the motor. According to the
Load circumstances, it can automatically adjust the motor speed and reduce the reactive
Impact of the motor starting on the grid. Meanwhile, through peripheral sensor, it can
Realize variable dynamic control to achieve the purpose of energy saving. Applicable to
Explosion-proof mine hoists, belt conveyor, scraper conveyor, pump station, fan etc. In the
Underground mines.

2. Characteristics

2.1 Adopt no-speed sensor vector. The output torque can reach 1.5 times rated torque at
0.5Hz. The largest torque is 2 times of the rated torque.
2.2 Heat pipe cooling ensures the cooling requirement of the equipment operation,
Reduces the system voice and realizes zero maintenance.
2.3 Wide frequency adjusting (2-16kHz) to meet demands of different occasions.
2.4 Different brake modes according to different loads: DC brake, dynamic brake, feedback
Brake
2.5 Human-Machine interface adopts intrinsically safe circuits for isolation purpose so that
It can ensure the equipment safety and convenient operation.
2.6 With protective functions of over-voltage, short-circuit, over-load, over-heating, phaseloss
Etc.
2.7 With standard RS-485 communication interface.
2.8 Good electromagnetic compatibility.
2.9 Remote diagnosis ability
