ZJSHUYI What is the function of the soft starter configuration bypass co...

There are two types of soft starters, one does not need an external contactor and runs directly after starting, and the other is a built-in bypass contactor. The contactor connected in parallel on the soft starter is called a bypass contactor, because the long-term use of the soft starter to start will cause a lot of pressure on the thyristor. If the thyristor is in an excessive current for a long time, and the thyristor is triggered by the circuit board at the same time, it will be prone to failure problems. It can be maintained with a traditional contactor, because the soft start is only useful in the process of starting the motor, and it is the same as that of a common motor during power frequency operation, so it is more reliable to use a traditional contactor. The soft starter is a device that can reduce the starting current of the AC motor when starting. When the motor completes the starting process, the device can start the bypass contactor according to the set time, thereby removing the soft start from the main circuit of the motor. The motor power circuit is connected by the bypass contactor and the motor's main contactor. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #contactor #ACcontactor #ZJSHUYI #BypassContactor #Chinashuyi #shuyitop
