If you are new to the electrical industry, you need to consider different courses, different training contents and different final training time. Please choose the training course that suits you according to the specific arrangement of the training course.

The most basic and commonly used electrician learning is high-voltage electrician, which is practical, and weak-current electrician needs to master more theoretical knowledge. Moreover, most of the weak current is integrated, which is generally not easy to break down, and the integrated circuit is not easy. It is recommended to learn to be a strong electrician.

With regard to high voltage, we must first understand the working principle and usage of commonly used switches, fuses, contactors, relays, time relays and thermal relays. And how to choose accessories according to the line requirements. Secondly, understand the principle and simplicity of motor, and understand the type and selection of motor.

Finally, understand the positive and negative rotation control circuit of the motor. Then from shallow to deep, such as motor positive and negative control circuit, automatic cycle control circuit, multi-control motor circuit, motor star angle step-down start circuit, motor braking circuit (multiple braking methods) and so on.

To learn electrotechnics, you must practice a lot, and you must understand the principle safely every time you practice a subject. As far as self-study is concerned, it is difficult to reach a certain level, so you can consider signing up for a study class.
