1. Countermeasures to the overheating problem of inverter
1. For places where the operating environment temperature of the inverter is high, it is recommended to reduce the temperature of the inverter and strengthen cooling and ventilation;
2. Increase the frequency of regular maintenance of inverter fans and air ducts, so as to improve the operating environment of the inverter and maintain the continuous heat dissipation capacity of the inverter;
3. To monitor the operating temperature of the inverter, it is recommended to use the color-changing temperature measurement patch method to monitor the heating situation of the inverter.
Second, the daily testing content of the inverter
1. Check whether the operation panel is normal;
2. Check whether the power supply voltage, output voltage, and DC voltage are normal;
3. Check whether the power supply wire and output wire are heated, deformed or burned out;
4. Check whether the cooling fan is running normally;
5. Check whether the radiator temperature is normal, etc.
3. Precautions for the use of inverter
1. The use of low-voltage frequency conversion is seriously affected by the environment, ensure that the surrounding environment is clean during application, and the temperature is controlled below 40 degrees, because the temperature is too high, it will seriously affect its life;
2. Disconnect the power supply when wiring, and use a multimeter to determine whether there is an external voltage;
3. The grounding end is well grounded;
4. Ensure that the humidity, temperature and cleanliness are appropriate;
5. The wiring layout is correct, the most important is the input and output lines;
6. Installation of cooling and ventilation equipment;
7. Select the high-frequency leakage switch before using the leakage switch;
8. It is forbidden to install compensation capacitors or capacitance limiters between the inverter and the motor, and it is forbidden to install electromagnetic contactors.
