I am engaged in electrical debugging of thermal power construction. The initial learning method is to look at more pictures in combination with the actual equipment, use multimeter, lighting and other equipment to check the wiring in the cabinet according to the drawings, understand the wiring mode, and then draw inferences. On the basis of a certain understanding, cultivate the ability to solve problems. Qualified secondary debugging personnel should not only be familiar with the circuit principle, but also pay attention to the ability to solve problems. This ability is accumulated over time. The more you do, the stronger your ability to deal with problems.
