inverter operation reliability
Through a large number of investigations and studies, it is found that the temperature will greatly affect the reliability of the operation of the inverter. If the inverter has a large power, the air cooling method is often applied, that is, the ventilation fan is properly installed on the top, so that the air can be better ventilated, and the hot air in the outdoor discharge cabinet is continuously deteriorated. The installation environment is effectively improved; because the frequency converter is completely enclosed, it needs to control its internal temperature below 50 degrees Celsius; but for the summer in the south, it is often hot, the temperature is usually above 50 degrees Celsius, to ensure the inverter To be able to operate normally and reliably, it is necessary to adopt a series of cooling devices, such as air conditioners. However, the application of these external devices, although the temperature is reduced in a short period of time; it will affect the normal ventilation, and the indoor noise will be greatly increased, so this measure is not reasonable and scientific. Therefore, we need to arrange the air-cooled position reasonably according to the specific situation. It is best to apply the ducted ventilation device to the top of the cabinet so that the indoor hot air can be directly discharged to the outside. In some special cases, it is also necessary to scientifically select the frequency converter according to the specific situation, and it is necessary to regularly repair and protect the parts that are prone to problems and avoid damage to the inverter.
5 Conclusion
Through the above narrative analysis, we can know that with the development of the times and the progress of social economy, the power demand of the society is getting bigger and bigger, the stability and safety of the operation of the power system will be on people's daily life and work. The long-term stability of the country has a direct impact; in response to this situation, it is necessary to continuously improve and improve the power system to better serve people's lives and social development. Through a lot of practical research, it shows that the application of variable frequency speed control technology to motor drag has a series of advantages and values, which can guarantee the safe and stable operation of the power system. The relevant staff needs constant efforts, innovative technology, summed up experience, and better applied the variable frequency speed control technology to the motor drag. The article briefly analyzes the practical application of the frequency conversion speed regulation technology in motor drag, and hopes to provide some valuable reference opinions.
