soft starter mass production



A soft starter continuously controls the motor's voltage supply during the start-up phase. This way, the motor is adjusted to the machine's load behavior. Mechanical operating equipment is accelerated smoothly. This lengthens service life, improves operating behavior, and smooths work flows.

Foreword: Inverter repairers must keep in mind that the inverter module and the drive circuit are strongly related to failures. When the inverter module bursts and damages, the drive circuit is bound to be damaged by impact. The damage of the inverter module may also be caused by the failure of the drive circuit. Therefore, whether it is a failure of the drive circuit or the inverter output circuit, it must be The inverter output circuit and the drive circuit are thoroughly inspected together. The power-on test of the main circuit must be carried out under the premise that the drive circuit is normal and can output six excitation pulses normally. Inverter power failure A 132KW inverter has a black screen fault. Part of the wire drawing machine stopped in the wire drawing workshop, and restarted production after half a month. As a result, the inverter went black after being powered on. It was judged that the switching power supply was faulty on the spot. The inverter was removed, and th...

Usually the soft start system is composed of softstart device, peripheral circuit and motor load. Therefore, the objects protected by the soft start system are also the soft start device, peripheral circuit and motor load. The purpose of protecting the soft start system is to ensure the safe and reliable operation of thyristor components, #softstarter equipment and circuits, and not damage or cause safety accidents under various abnormal working conditions. The premise of #softstarter protection is that the design of the soft starter itself should be correct. The thyristor components are correct and used correctly, the drive circuit and the control circuit are reasonably designed and matched with each other, so that the device can work in a good state. These measures are the basis for the safe and reliable operation of the soft starter. Only under this premise, can the devices, circuits, and equipment fail less and not fail from the inside, and the optimized system design should aim ...

The dual power switch is a switch that automatically switches to another power source due to a power failure. General dual power switch is widely used in high-rise buildings, residential areas, hospitals, airports, docks, fire protection, metallurgy, chemical industry, textiles and other important places where power failure is not allowed Beautiful appearance, reliable quality, long life and simple operation. It consists of two three-pole or four-pole molded case circuit breakers and their accessories (auxiliary and alarm contacts), mechanical interlocking transmission mechanism, and intelligent controller. It is divided into two structures: integral type and split type dual power supply new products. The integral type is that the controller and the actuator are installed on the same base; the split type is that the controller is installed on the panel of the cabinet, and the actuator is installed on the base and installed in the cabinet by the user. cable connection. www.shuyitop.com;...
