Application: this product is applied to soft starting, soft stopping, operation process control and energy-saving application of motor in harsh environment such as coal mine, other mines, petroleum and chemical industry.
This soft starter is suitable for coal mines containing explosive gas (methane) and coal dust. In AC 50Hz, voltage 1140V or 660V, neutral point ungrounded power supply system, perform various forms of soft starting (such as current limit, voltage ramp and power torque ramp for three-phase squirrel cage motors with currents below 200A and 400A) ) . It also has perfect protection function and fault display function, which greatly reduces the troubleshooting time.
KJS series of mine spray dust suppression blower (formerly JPK-3 mine hydrodynamic spray dust collector) is used for dust removal in belt roadway, return roadway and coal face.
It is one of the power control power distribution equipment which is widely used in low voltage distribution system at present. Due to its easy installation, flexible use, easy to maintain, economical and luxurious.
