ZJSHUYI Debug sequence of soft starter.www.shuyitop.com; #softstarter

Debug sequence of soft starter: 1. Selection of starting mode and starting time of soft starter: ① For soft starters of general power, the larger the load, the longer the starting time; ② When the quality of power supply of the power grid is relatively high, the current limit start can be selected, and the same load The larger the value, the longer the startup time should be. 2. Check whether the motor can rotate normally and flexibly, otherwise it will never start. 3. Check the parameters of the fan, motor and soft starter. Parameters checked include voltage, current, power, and the number of poles of the motor. 4. The commissioning sequence is manual cranking, air-dropping control loop, motor idling, and running with load. 5. Check the insulation resistance of the motor. This work must be done before the motor is connected to the soft starter, because the starting circuit is composed of thyristor components. When the motor and the soft starter are connected, if the motor insulation resistance is measured with a high-voltage megohmmeter, the thyristor will be damaged. . www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #solidstatesoftstarter #acmotorstarter

ZJSHUYI Do you know what is a fire control cabinet? www.shuyitop.com; #S...

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
