Autotransformer starter cabinet, using the step-down autotransformer characteristics, starting when the power supply voltage is applied to the motor winding part, the starting current is reduced over a period of time after setting, and then all of the voltage applied to the motor windings, the motor to accelerate to rated speed.Its biggest advantage is relative to the total pressure can largely reduce the starter motor starting grid impact. To ensure the normal operation of the motor, the line has lost pressure, short circuit, phase, overload protection devices. SXLZQ series start cabinet pumps are widely used in various types of supporting applications.
