What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Inverter environment temperature(1) working temperature. The use of frequency converter should pay attention to the environmental matters, the internal is high-power electronic components, is easily affected by the operating temperature, the product is generally required to be 0~55 degrees, but in order to ensure safe and reliable work, when usedShould be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements of the product manual, absolutely not allowed to sendA heat element or a heat generating element is mounted close to the bottom of the inverter.
General environment temperature: inverter is an electronic device, containing electronic components, electrolytic capacitors, etc., so the temperature has a greater impact on its life. The environment of general inverter operating temperature of ~+50 DEG C - General requirements, if it can reduce the operation temperature of inverter, prolongs the service life of the transducer, stable performance. So heat dissipation is very important.
Vibration and shock. The control cabinet equipped with frequency converter will cause bad electrical contact when subjected to mechanical vibration and shock. At this time, in addition to improving the mechanical strength of the control cabinet, away from the vibration source and shockShock source should also use shock rubber pads, fixed outside the control cabinet and internal electromagnetic switches and other parts of the vibration generated. After running for a period of time, the equipment should be inspected and maintained.
Ambient temperature. When the temperature of converter is too high and the temperature changes greatly, the inner of converter is prone to dew. The insulation performance will be greatly reduced, and even short-circuit accident may occur. If necessary, a desiccant and heater must be added to the case.(3) corrosive gases. The use of the environment, if the corrosive gas concentration is large, not only will corrode the components of the lead, printed circuit boards, etc., but also accelerate the aging of plastic devices, reduce insulationIn this case, the control box shall be made into a closed structure and ventilated.
