Solid state relays are non-contact switches composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control terminal and the load terminal. The input end of the solid state relay uses a tiny control signal to directly drive a large current load. Solid-state relay is a new type of non-contact switching device composed of solid-state electronic components. It uses the switching characteristics of electronic components (such as switching transistors, triacs and other semiconductor devices) to achieve non-contact and non-spark switching. And the purpose of disconnecting the circuit, so it is also called "non-contact switch". Solid state relay is a four-terminal active device, two terminals are input control terminals, and the other two terminals are output controlled terminals. It has both amplifying and driving functions and isolation functions, which is very suitable for driving high-power switching actuators , Compared with electromagnetic relays, it has higher reliability, and has no contacts, long life, fast speed, and little interference to the outside world, and has been widely used.

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...
