What are the precautions when using INVT converters at high temperatures
The frequency converter is a commonly used power control system. The inverter is also used at high temperatures, so What are the issues to be aware of when using at high temperatures?
Invitrogen Inverter Manufacturers say that the wide-angle automation equipment is used as Weiluntong, Delta, Yonghong, Yingweiteng, Parker, Mitsubishi, Siemens, Continental, Physicochemical, The first-class agents of international companies such as Sifang and other companies have developed into the vanguard of the industrial control industry. At present, the product quality, service level, business scope and market share of the company's automation equipment are ranked first in the country.
1. Carefully monitor and record the various parameters on the human-machine interface of the inverter, and find that the abnormality should be reflected immediately.
2. Monitor and record the ambient temperature of the inverter room and the ambient temperature carefully. It should be between -5 ° C and 40 ° C. The temperature rise of the phase shifting transformer should not exceed 130 °C.
3. When the summer temperature is high, the ventilation and heat dissipation of the inverter installation site should be strengthened. Ensure that the surrounding air does not contain excessive dust, acid, salt, corrosive and explosive gases.
4. Summer is rainy, and rain should be prevented from entering the inverter (for example, rainwater enters the air outlet)<>
5. The filter on the inverter door should be cleaned once a week. If the working environment is dusty, the cleaning interval should be shortened according to the actual situation.
6. The inverter is normal. During operation, a standard thickness of A4 paper should be firmly adsorbed on the air inlet filter screen of the cabinet door.
7. The frequency conversion room needs to be kept clean and tidy, and should be cleaned at any time according to the actual situation on site.
8. The ventilation and lighting of the inverter room must be outstanding, and the ventilation and heat dissipation equipment (air conditioner, ventilation fan, etc.) can operate normally.
