If the soft start of the motor cannot protect, it means that your parameter setting is unreasonable, or even the function setting is wrong. 1. Soft start is used to start the motor to prevent too much starting current from impacting the power grid when starting. The soft-start device is only active during the start-up process. 2. Motor burning prevention is the responsibility of the motor's overload protection device. The simplest fuse is generally a thermal resistance. But the general soft starter can be achieved. 3. The motor still burns, indicating that your circuit design is unreasonable. The configuration of the device is not reasonable. Or not consider overload protection at all. I thought that as long as it was installed, it would provide overload protection. In fact, it needs to be debugged first. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #...

During the starting process of the soft starter motor, the conduction angle of the thyristor gradually increases, the output voltage of the thyristor also gradually increases, and the motor accelerates from zero until the thyristor is fully turned on and the start is completed, thereby realizing the stepless smooth start of the motor. The maximum starting torque and starting current of the soft starter motor can be set according to the load. The main composition of the soft starter is a three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. Different methods can be used to control the conduction angle of the three-phase parallel thyristor, so that the input voltage of the controlled motor changes according to different requirements, and different functions can be realized. Soft starters and frequency converters are two completely different products. The frequency converter is used where speed regulation i...

ZJSHUYI Why use a soft starter.#softstarter www.shuyitop.com;

Now the long used in transmission engineering is three-phase asynchronous motor. In many cases, these motors cannot be directly connected to the power system due to their starting characteristics. If started directly on line, a surge current of 6 times the rated current of the motor will be generated, which can overload the supply system and the series switchgear. If it is started directly, it will also produce a higher peak torque. This impact will not only impact the driving motor, but also make the mechanical device under load. For example, auxiliary power transmission components. To reduce the starting current, start auxiliary devices, such as starting reactors or autotransformers, should be used. However, this method can only gradually reduce the voltage, while the soft starter can realize non-impact starting by smoothly increasing the voltage of the gao terminal. Can better protect the power system and motor. Web:www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355...
