Top 10 tortures of frequency converters

Top 10 tortures of frequency converters

There are ten major "tortures" of inverters today, which can also make your inverter suffer. Let's follow the editor of okmarts.com to explore the top ten "tortures" that will make your inverter "death than life"!

　　One of the top ten "tortures" of frequency converters: loading

　　Long-time heavy load will not only affect the life of the motor, but also damage your inverter and shorten the life of the inverter.

　　 The second of the top ten "tortures" of frequency converters: sauna

　　 The surrounding temperature is too high, the fan is blocked, the performance of the temperature sensor is poor, and the motor is overheated. Never do maintenance for the inverter, the inverter also needs frequent and periodic maintenance and maintenance.

　　 The third of the ten "tortures" of frequency converters: undervoltage

　　 Insufficient power supply voltage and generator voltage, and frequent undervoltage of the inverter can easily cause damage to internal components!

　　 Four of the top ten "tortures" of frequency converters: rain

　　Before the inverter is installed and debugged, it is in a humid environment; after the inverter is running, the working environment is relatively harsh, and rainwater enters the inverter from time to time. The electrical components of the inverter are in a humid environment for a long time, which is greatly harmful to the circuit board.

　　Fifth of the ten "tortures" of frequency converters: lightning strike

　　 The inverter is not grounded and lightning protection measures are not installed in accordance with the requirements of the equipment manufacturer! The inverter is easily damaged during thunderstorm.

　　 Ten "tortures" of frequency converters sixth: overvoltage

　　 The power supply voltage, the generator set voltage is too high, and the inverter power supply for a long time may cause damage to the internal components!

　　7 of the top ten "tortures" of frequency converters: Corrosion

　　Due to corrosive gas caused by toggle switches, poor relay contact, corrosive gas caused short circuit between crystals, terminal corrosion caused short circuit of the main circuit, circuit board corrosion caused short circuit between devices.

　　 Eight of the ten "tortures" of frequency converters: trampoline

　　All the inverters are installed on the same rigid foundation, or the foundation is too weak, and the foundation cannot provide enough strength to restrain the operation vibration of the inverter. The inverter is like a trampoline, "jumping" constantly.

　　 Ten major "tortures" of frequency converters Nine: Cold violence

The inverter has never received enough "care". The user does not inspect and maintain the inverter as required by the manufacturer, or does not replace the fan for many years, does not blow dust to the inverter, and does not check the loosening of the screws, which makes the inverter "Small ailments incurable" to "serious incurable diseases".

　　 Ten of the top ten "tortures" of frequency converters: a small horse-drawn cart

　　 Inaccurate selection will cause the inverter to be overloaded, the phenomenon of small horse-drawn carts, and the parameters are not adjusted to the best use state, so that the inverter will frequently overcurrent, overvoltage and other frequent trip protection, premature fatigue and damage.
