Soft starter fault shows how to do soft start overheating

With the rapid development of the industry, more and more manufacturers of soft starters are used, and the problems that come with them are increasing. The company is a R&D and manufacturing company with 15 years of industry experience. , two problems seen in xx know:

What should I do if the soft starter fault indicates that the soft start is overheated?

Sinol Electric believes that it is necessary to protect the soft starter from overheating. It not only protects the thyristor, but also protects the motor. The design is considered to be good, even when the startup is completed, the protection of the motor can be completed when switching to the contactor circuit. The main circuit has 3 incoming ends and 6 outgoing ends. The outgoing line to the bypass contactor passes through the transformer in the soft starter. The protection device in the soft starter detects the current through the contactor after bypassing. , complete the protection of the motor.

How does soft start reduce the starting current?

Soft start usually reduces the starting current by lowering the voltage of the motor terminal, but the way of stepping down is not the same. The soft start of thyristor is to adjust the output voltage by adjusting the conduction angle. The resistance reactance is to adjust the series voltage by adjusting the impedance. The transformer regulates the output voltage by adjusting the primary to digital ratio.

Sinol Electric will post it from time to time, knowing that the platform will answer some questions about soft starters and inverters.
