high voltage solid soft starter (hereinafter referred to as
soft starter) is a c designed with up-to-date concept,and
mainly applicable to the control of and protection for the starting
and stopping of squirrel-cage type asynchronous and synchronous
motors.The starter is composed of several thyristor in
series-parallel,and it can meet different current and voltage
requirements. The Product is widely used in
electric industry with rated voltage 3000 to 10000
V, building materials, chemical industry, metallurgy,
steel and paper-making industries etc.. And can
perform well if used together with various kinds of
electromechanical devices including water pumps,fans,compressors,
crashes, agitators and conveyer belt etc..It is the ideal device
for starting and protecting high voltage motors. Basic

starterMedium voltage solid soft starter PrincipleThe
reactance is connected in series in the stator circuit of the
motor, and the starting multiple control of the current is realized
by sharing the voltage at the motor end. Parallel
thyristors are connected in series in the stator circuit of the
motor, and the conduction angle of the thyristor is adjusted
through the closed-loop control system to gradually increase the
motor terminal voltage and realize the starting of the
motor. voltage executionreactorthyristor (SCR) usage
