Although the frequency converter maintenance technology is simple and easy to learn, it needs to be widely involved in some other frontier industries, such as touch screen, DCS configuration, programmable controller control, single chip microcomputer, computer-aided equipment and so on. The type of technology cannot be too single, otherwise the employment will be very narrow.
However, if you really want to get a good salary, you must keep learning and making progress, because the inverter will not be eliminated, but will only be upgraded. Therefore, inverter maintenance personnel need to learn and communicate constantly.
Frequency converter maintenance technology should be as skilled as possible. The technical type is most afraid of others saying "half a bottle of water". It can be said that if the inverter maintenance is only to replace the template and accessories, then almost most maintenance electricians can complete it, and there is relatively no high-end technology. The higher the technology, the lower the possibility of being replaced, the more valuable and the more promising.
If you don't have time, you can choose to buy a book about electronic components or a set of video tutorials to teach yourself from scratch. For example, Pingliang School, which specializes in inverter maintenance, has its own developed tutorials for sale. I bought a set that I think is good.
However, self-study still depends on your perseverance and learning ability. After all, there is nothing that others teach you directly. You can only figure it out for yourself. If you have time, I suggest you go to a good on-site training class. There are teachers to teach you, equipment to practice, a group of people to study together, and a learning atmosphere that is easy to adhere to.
