First energize the soft start and then press the start button. When the number displayed on the screen reaches 100 percent, the motor starts to complete. When you want to stop the motor, press the stop button, the motor will stop running. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters

Fire control cabinet (automatic control cabinet) is a kind of industrial control equipment that is more common in our lives, such as corridors, underground parking lots, gas stations and other public places. However, many friends do not know what it is called or what it is used for. The following ZJSHUI editor will explain what is a fire control cabinet. The fire control cabinet is a safe fire fighting tool provided by the pump factory. Its main purpose is to protect the pump motor from overvoltage, short circuit and overload. And also has a sound and light alarm function. It plays an important role in extinguishing fire and is also a fire safety device that can help control the fire after a fire occurs. There are many ways to start the control cabinet, including direct start, soft start, star-delta start, auto-coupling start, etc. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #ZJSHUYI #Softstartcabinet

ZJSHUYI Common problems of soft starters. www.shuyitop.com; #softstarte...

1. The motor can't get up There are two reasons why the motor cannot start. One is that one of the six thyristors is unreliable or non-conductive, the one-phase circuit passes half-wave DC, and the two-phase winding of the motor passes through the DC to start the motor. When the braking effect is reached, not only the motor cannot be started, but also the motor and the thyristor will be burned in serious cases. The second is that the motor cannot be started due to improper starting parameters or starting curve, which is the most common fault problem. 2. The thyristor is burnt The thyristor is destroyed or exploded. This kind of failure has nothing to do with domestic and foreign brands, but the failure rate is lower than that of the contactor. The main problem appears in the installation technology of the pie-type thyristor. 3. Controller burnout Compared with the soft starter, the controller burns the most seriously. Some manufacturers have this failure with repair rates in excess

ZJSHUYI ZJSHUYI Difference between soft starter and frequency converter....

First of all, the purpose of the soft starter and the frequency converter is different. The main problem solved by the soft starter is to reduce the starting current of the large load and reduce the impact on the power grid. The startup of large equipment will generate a very large startup current, which will cause a large voltage drop. If the traditional star-delta and other step-down methods are used, it will not only cause a larger current impact to the power grid, but also cause a larger load to the load. Mechanical shock, in this case, a soft starter is often used to start, to achieve no shock throughout the start, so that the motor starts more smoothly, thereby reducing the capacity of the power supply. The frequency converter is mainly used in places with speed regulation. It can control the speed of the three-phase motor, such as the speed regulation of the spindle motor of CNC machine tools, the transmission control of mechanical conveyor belts, large fans, and heavy-duty mach
