Learning Electrical Technology Easily from scratch (2nd Edition) is an introductory book on electrical technology, which is divided into 9 chapters. The main contents include the installation of electrical foundation, electrical instruments, low-voltage appliances, electronic components, transformers, motors, motor control lines, indoor distribution lines and safe use of electricity.
Read some books about circuit examples! It is best to be comprehensive. Whether you are learning to install electricians or repair electricians, you should learn from your own practice. But some people should have the best spirit and ask if they don't understand, so there should be no problem and give full play to themselves.
This industry is quite special, and the country needs textual research, which is very formal. The best thing is that people who work in factories can teach themselves, because they can be led by teachers and can actually operate.
High-end-circuit, electronic technology foundation (digital electricity and analog electricity), engineering electromagnetic field, Electromechanics, power engineering foundation, automatic control theory, power system (transient and steady state) analysis, power system relay protection, power plant electrical main system, high voltage technology, PLC, computer control technology (single chip microcomputer)
2. Look for it in Xinhua Bookstore (learn electrician technology easily from scratch), and at least know the lighting circuit first. Such as two-position control, three-position control, daily turn-off circuit, calculation method of current, different calculation methods of 220v and 380V, selection of line diameter, etc. The selection of fuse switch socket size, electrical safety technology, lighting, after understanding, I am learning power control, which is a common electrical control in the factory. I suggest you have a look (electrical control and PLC). It is not difficult to start from the basics, such as motor protection, motor forward and backward control, star delta step-down start, two motors start control successively, automatic forward and backward control and so on. The secondary circuit can certainly do it. Many people who do home improvement on the construction site don't know the secondary loop above, and they are self-righteous. Just learn these first. It is almost enough to learn these things at the grassroots level, but if you want to be a skilled worker who can be respected by others, you must learn more. Further, such as plc, frequency converter, touch screen configuration monitoring, soft starter, servo controller, stepping motor control, sensor encoder, pneumatic transmission, hydraulic transmission, etc. are all the contents of factory automation control.
The above is low voltage. If you want to do this job well, you can also learn from high-voltage substations. Most factories have 10kv substations, and some have 35KV, 1 10KV substations. The high-voltage electrician on duty should be able to operate circuit breakers, relay protection and analyze field operations. I suggest you go to the power supply bureau to train electricians to enter the network.
