Soft starter is a novel motor control device that integrates motor soft start, soft stop, light load energy saving and various protection functions. The main composition 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. The soft starter changes the starting characteristics of the motor by changing the output voltage and boost time. The soft starter uses a three-phase parallel thyristor as a voltage regulator, which is connected between the power supply and the motor stator. Such a circuit is like a three-phase fully-controlled bridge rectifier circuit. When the soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on, and the motor works on the mechanical characteristics of the rated voltage to achieve smooth starting, reduce starting current, and avoid starting overcurrent tripping. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice#builtinbypasssoftstarter #softstartcabinet #ZJSHUYI #Chinashuyi#shuyitop

Maintenance requirements in the day-to-day operation of the frequency converter 1. Check whether the cooling system is normal, and clean the dust of the air filter. 2. Check whether the screws, bolts and other fasteners of the inverter are loose, and perform necessary tightening; for the parts with soldering and crimping terminals, check whether there is corrosion, discoloration, cracks, damage, etc., and also check the frame Whether the structural parts are loose, whether the conductors and wires are damaged, etc. 3. Check whether the connection of the control circuit board is loose, whether the capacitor is leaking, whether the lines on the board are rusted, broken, etc. 4. Check whether the filter capacitor is leaking and whether the capacitance is reduced. 5. Check whether the insulation resistance is within the normal range. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #VFD #INVERTER #frequencyinverter #frequencyconverter #shuyitop #converter ...

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 ...

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...
