soft starter
Magnetically controlled soft starter is an innovative standard product, which makes the drive system more flexible and lower cost.
Magnetic control soft starter device straight road, only in May 2002 the first domestic high voltage products come out. Novelty search shows that these products are not produced abroad. It is derived from reactor start-up. It is the common point that the reactance is connected in series in the stator of the motor to realize the depressurization. The magnetically controlled soft start is different from the soft start time of the reactor, and the air saturation and the reactor replace the fixed reactor. The saturable reactor is bypassed after start-up.
In the magnetically controlled soft start device, the SCR controls the motor current by amplifying the power and voltage of the saturable reactor. Unlike in thyristor soft start devices where high voltage and high current are saturated reactors. Magnetic control soft start from the following technical advantages: 1, reliable; 2, cheap; 3, the environmental requirements are not high.
