变频器的发展特征和使用中的注意事项

Development Characteristic of Converter and Notice in Use

交流化是电气驱动今后的发展趋势,作为核心部分的变频器也正朝着高性价比、多功能化、小型轻量化发展。当变频器工作时,输出电流的谐波电流会对电源造成干扰,因此对谐波的治理成为变频器选型和使用中最需要关注的问题。另外,正确使用变频器还要从物理环境、电气环境、接地、防雷等方面多加注意,否则可能会造成变频器的损坏或人员伤害。

AC control is the trend of electric drive in the future, and the converter as the heart is developing to high capability-price ratio, multifunction, minitype. When the converter is working, harmonic wave of output current will disturb power supply, so the management of harmonic wave becomes the most important problem. In addition, high attention should be paid to physical environment, electric environment, grounding and lightningproof when using converter. Otherwise, it＇ll damage converters or hurt people.
