Ten dangerous restricted areas of the inverter
One of the ten dangerous restricted zones of the inverter: overvoltage
The power supply voltage and the genset voltage are too high, and the internal power supply is too high for a long time.
The top ten dangerous zones of the inverter: sandstorm
Conductive dust such as metal, excessive dust causes short circuit of the main circuit or dust is blocked. The temperature of the cooling fin is too high, causing tripping and burning.
The top ten dangerous restricted area of the inverter: flood
Before the inverter is installed and debugged, it is in a humid environment; the inverter is in operation and use, the working environment is bad, there will be condensation of water vapor or oil mist, oil mist, etc., causing the electrical components to be in a humid environment for a long time, on the circuit board and The insulation structure causes damage.
The top ten dangerous restricted area of the inverter: sauna
If the ambient temperature is too high, the fan is blocked, and the motor is overheated, the inverter cannot effectively dissipate heat, affecting the service life of the machine and causing damage to the machine.
The ten-sided danger zone of the inverter is five: loading
Excessive load for a long time will not only affect the life of the motor, but also damage the inverter and affect its service life.
Six of the ten dangerous zones of the inverter: undervoltage
The power supply voltage and the genset voltage are not enough, which makes the inverter frequently undervoltage, which may cause internal components to be damaged.
Seven of the ten dangerous restricted zones of the inverter: corrosion
Poor switching of switches and relays due to corrosive gases; short circuit between crystals due to corrosive gases, short circuit of main circuit due to corrosion of terminals, and short circuit between devices due to corrosion of circuit boards.
Eight of the ten dangerous restricted zones of the inverter: lightning strike
Did not follow the requirements of the equipment manufacturer, did not ground the inverter and install lightning protection measures! The inverter is easily damaged during thunderstorms!
Nine of the ten dangerous restricted zones of the inverter: cold violence
The user does not check the differential and regularly maintain the inverter according to the requirements, or does not replace the fan for many years, and does not check the usage and damage degree of the machine parts.
Ten of the ten dangerous zones in the inverter: mismatched
