Background

The Soft Starter is a novel motor control device integrating the functions of Soft starting, Soft stopping, light load energy saving and multiple protection functions of a motor, and is called Soft Starter abroad. The main structure of the device is a three-phase anti-parallel thyristor and an electronic control circuit thereof, which are connected in series between a power supply and a controlled motor. Different methods are used to control the conduction angle of the three-phase anti-parallel brake tube, so that the input voltage of the controlled motor can be changed according to different requirements, and different functions can be realized.

The soft starter is actually a voltage regulator, and when the motor is started, the output only changes the voltage and does not change the frequency. The frequency converter has all functions of the soft starter, but the price of the frequency converter is much more expensive than that of the soft starter, and the structure of the frequency converter is also much more complex. The soft starter of the motor is characterized in that a soft starter connected between a power supply and a controlled motor in series is used for controlling the conduction angle of a thyristor in the soft starter to enable the input voltage of the motor to gradually rise from zero in a preset function relation until the start is finished, and the full voltage is given to the motor, namely the soft start.

When the soft starter is installed, the soft starter should be vertically installed in the protection cabinet, and a space of 200mm should be left above and below the soft starter, so as to facilitate heat dissipation.

The existing protection cabinet for the soft starter is mostly of a sealing structure, the heat dissipation effect is poor, and the service life of the internal soft starter is easily influenced.
