浅谈通用变频器的保护功能

On the Protection Function of General Inverter

变频器在日常生活中的应用已经随处可见,但很多人对它的认识就只是变频而已。事实上,它在改变频率的同时还具有一定保护功能。了解各类变频器的保护功能,对于正确使用变频器及故障的排查非常重要。本文主要详细介绍变频器在运行过程中的过电流保护功能、过载保护功能、过电压保护功能、欠电压的保护功能。

Inverter applications in daily life has been everywhere, but many people know it only on the frequency only.In fact, it＇s also changing the frequency of a certain protection.Unders- tand the various types of inverter protection, for the proper use of the inverter and failure investigation is very important. This paper describes in detail the process of running the inverter over-current protection,overload protection,over voltage protec- tion, under voltage protection.
