The correct settlement of frequency conversion power will help the normal development of product function, enhance its stability, safety and application instructions. Next, introduce the related matters needing attention in the following aspects.
Good lubrication, 1 speed variable frequency power supply, high efficiency. At low speed, the characteristic static rate is high and the relative stability is good.
2. The environment temperature of the use of frequency conversion power is generally applicable to -10 - 40 C, and the humidity is less than 90. If the ambient temperature is higher than 40 C, every 1 C is raised, and the frequency conversion should be reduced by 5. The ambient temperature is 10 DEG C per liter, inverter life binary, so the surrounding environment temperature and converter cooling problems must be handled well.
3, 60HZ power, 400HZ intermediate frequency power supply, inverter power, shore power supply, single-phase variable frequency power supply, three-phase variable frequency power supply and other power products should be far away from fire source and high temperature, so as to prevent high temperature.
4, prevent the oil mist and salt from the corrosion of the frequency conversion power.
5, please put the frequency conversion power in the outstanding ventilation of the local, around at least 30 centimeters from other objects to adhere to the air inlet ventilation.
6. The normal working environment of the frequency conversion power supply is from 0 to 40 C, and the humidity is 0 ~ 90% (non condensation).
7, to prevent the conversion of the power source into the locals with corrosive gases and oscillations and magnetic disturbances.
8, prevent the frequency of the power supply in direct sunlight, rain or wet land.
9, do not put 60HZ power, 400HZ medium frequency power and other various power products in the uneven or skewed place.
10, when the frequency conversion power is driven by the standard motor, the loss will be added when compared with the power frequency power supply. The effect of low speed cooling is worse and the temperature rise of the motor will be added. Therefore, the load torque of the motor should be reduced at low speed.
To sum up, as a variable frequency power supply operator, we should comply with the operation instructions of products, or seek technical support from frequency conversion power suppliers, so as to ensure that the power supply is settled and standardized, so as to ensure its operation.
