物理环境 1)工作温度。变频器内部是大功率的电子元件,极易受到工作温度的影响,产品一般要求为0～55℃,但为了保证工作安全、可靠,使用时应考虑留有余地,最好控制在40℃以下。在控制箱中,变频器一般应安装在箱体上部,并严格遵守产品说明书中的安装要求,绝对不允许把发热元件或易发热的元件紧靠变频器的底部安装。 2)环境温度。温度太高且温度变化较大时,变频器内部易出现结露现象,其绝缘性能就会大大降低,甚至可能引发短路事故。必要时,必须在箱中增加干燥剂和加热器。 3)腐蚀性气体。使用环境如果腐蚀性气体浓度大,不仅
Physical environment 1) Operating temperature. Inverter is a high-power electronic components inside, highly susceptible to the impact of the working temperature, the product is generally required 0 ~ 55 ℃, but in order to ensure safe and reliable work, use should be considered to leave room, the best control at 40 ℃ below . In the control box, the inverter should generally be installed in the upper part of the box, and strictly comply with the installation instructions in the product manual, it is absolutely not allowed to install the heating element or easy-heating element close to the bottom of the inverter. 2) Ambient temperature. When the temperature is too high and the temperature changes greatly, dew condensation easily occurs inside the inverter, and its insulation performance will be greatly reduced, and may even cause a short circuit accident. If necessary, desiccant and heater must be added to the tank. 3) corrosive gas. Use environment If corrosive gas concentration, not only
