First, over current (short circuit)
Overcurrent faults are most common among various faults in the frequency converter. This fault is mostly caused by the following problems: First, as long as the inverter speeds up, it reports a fault, indicating that the overcurrent is very serious, mostly the load short circuit, mechanical parts are stuck, the inverter module is soft breakdown damage and the acceleration time is over. Shortly caused; secondly, the inverter reports a fault when it is powered, and it cannot be "reset" to be excluded. Most of it is caused by damage to the internal drive circuit of the inverter and damage to the current detection circuit. The last phenomenon is the most extreme. When the power is turned on instantaneously or after a short delay, it directly causes the upper air to trip and the internal fuselage is blown out or sparks. The inverter rectifier unit and the power inverter component directly cause breakdown failure. Second, over voltage This kind of fault phenomenon also often appears in the inverter fault. In addition to eliminating the supply voltage is too high, there is also a case of such a fault - when the inverter is stopped. The main reason for this may be caused by a slow deceleration time or a problem with the braking resistor and the brake unit.
Third, undervoltage in the above overvoltage fault corresponds to the inverter undervoltage fault, generally in the exclusion of the power supply voltage is too low, there may be several reasons: power supply phase loss, rectifier circuit, an open fault of a bridge arm, The capacity of the filter electrolytic capacitor in the main circuit becomes small, or the voltage detection circuit has a problem, which may cause an undervoltage fault of the inverter. In addition, if the internal slow-resistance of the inverter is not cut off by short circuit, an undervoltage fault will occur as long as the inverter is started.
4. Over-temperature and over-temperature are also a common fault of the inverter. This fault is mostly caused by the temperature of the inverter working environment is too high, the cooling holes are blocked, the cooling fan is damaged, the temperature sensor and the temperature detection circuit are damaged. .
Through the above analysis of the four common faults of the inverter (of course, faults such as overload and output imbalance), it is not difficult for the peers to see that the inverter needs to work harder in daily maintenance, and more needs to be done. We can use it flexibly according to the situation on the spot, and try our best to prevent it before it happens!
