QJZ Mining Flame-Proof Intrinsic-Safety Vacuum Electromagnetic Starter (Intelligentized)

Product features

1.Intelligent mathematic SCM control.
2.Select tailor-made module
3.With the function of self-diagnose.
4.Can control restrict current start and voltage incline electric wave
5.Function of pulse flounce sudden: use for super high stillness friction load.
6.Pump control: six curves can be selected, can prevent over hydraulic pressure and stop of the water hammer phenomena when soft start-up.
7.Automatic protect function: Automatic protect function of over voltage, lack of voltage, phase-failure, creepage, over current, short-circuit, over hot, long start time, too long restrict current time

Application

The series starter is mainly used to control of mining flame-proof three phases asynchronous motor with frequency 50Hz, rated voltage 660V or 1140V, rated power 60 to 400 kw., It can make motor always continually starting any instance, protect dragging system, reduce impact to electricity meshwork made by start current, protect reliable starting of motor.  It can be directly or remotely controlled, and make reversing when controlled motor stops.
