Start Up Cabinets For Mine Use - China

Product introduction

This series of starting cabinet products are suitable for AC 50HZ (or 60HZ), the voltage is 38OV or 66OV, the power is 11-300KW three-phase squirrel cage motor, water pump, etc., as a step down start, and can accelerate the motor to the rated speed and stop the motor.

It can protect the motor from overload, phase break and short circuit.

Overload protection of starting aging is provided for the autotransformer.

Products meet the standard: GB14048.4; Rated insulation voltage: AC380V; Rated impulse withstand voltage: 6V, rated working voltage: AC380V; Use category AC-3; Rated control power supply voltage: AC380V50HZ: Insulation class of transformer: Class B.

And because the current relation of the primary side of the transformer I1=I2/K, it can be seen that the current of the primary side (that is, the starting current of the power supply motor) is smaller than that flowing directly through the fixed subwinding of the motor, that is, the starting current of the power supply motor is 1/K2 times of the direct starting.

Since the voltage is reduced to 1/K times, the torque of the motor is also reduced to 1/K2 times.

The secondary side of the auto transformer has 2 to 3 groups of taps, such as the secondary voltage is 80% and 60% of the original side voltage.
