Advantages Of Soft Starter Over Traditional Decompression Equipment

- Jul 27, 2017 -

The modern industrial production, the soft starter has gradually to the traditional way of decompression is eliminated, the two start difference but there are still a lot of people do not know, here's AIKE soft starter small series will give you a simple introduction.

First, the use of soft starter is no impact current, and decompression start is not to reduce the impact of the current. The principle is that when the soft starter starts the motor, the starting current of the motor is raised linearly from zero to the setting value by gradually increasing the turn-on angle of the thyristor.

Because no impact on the motor, improve the reliability of power supply, smooth start, reduce the impact torque of the load machine, and extend the service life of the machine.

Secondly, soft starter has soft stop function, which can decelerate smoothly and stop gradually.

This can reduce the impact of heavy machinery when the motor is out of power, avoid the water hammer effect, and reduce equipment damage.

At the same time, the starting parameters can be adjusted. According to the load conditions and the characteristics of the grid protection, it can be adjusted freely to the best starting current.

Therefore, the soft starter for the traditional decompression mode still has many advantages, but for some protection function requirements are not too high occasions, or traditional decompression equipment cheaper.
