Frequency converter precautions at high temperatures

Inverter will severely shorten the command at high temperature, and it will also fry the module and fry the capacitor. Therefore, it must not work under high temperature in high temperature. In addition, the cost of spare parts for inverter maintenance in foreign countries is quite high. Therefore, the inverter must pay attention to some matters when it is used in a high temperature environment to avoid damage to the inverter.

1. Carefully monitor and record the display parameters on the inverter's man-machine interface, and find that abnormalities should be immediately reflected. 2. Carefully monitor and record the ambient temperature of the inverter room. The ambient temperature should be between -5°C and 40°C. Temperature rise of phase-shifting transformers cannot exceed 130°C

3. When the summer temperature is high, the ventilation and heat dissipation at the installation site of the inverter shall be strengthened. Ensure that the surrounding air does not contain excessive amounts of dust, acids, salts, corrosive and explosive gases. 4. In summer, it is a rainy season. Prevent rainwater from entering the inverter (for example, enter the outlet of a rainy air outlet).

5. The filter on the frequency converter cabinet door should normally be cleaned once a week; if the working environment has more dust, the cleaning interval should also be shortened according to the actual situation. 6. In the normal operation of the inverter, a standard thickness of A4 paper should be able to be strong Adsorption on the door inlet filter net 7, frequency conversion room must be kept clean and tidy, should be cleaned at any time according to the actual situation at the scene.

8. The ventilation and lighting of the frequency conversion room must be good, and the ventilation and cooling equipment (air conditioning, ventilation fan, etc.) can operate normally.

The inverter in high temperature environment is easy to damage, so the above content needs attention, and we hope to provide some help for everyone to use the inverter.
