How to learn to read electrical diagrams
Thread Content
Where can I find materials for learning electrical diagrams?
You can reply to your own posts, but not to others’ posts
I remember there is an introduction in the appendix at the back of \"Analog Electronic Technology\"
The best way is to ask using the drawings and then remember them well! Accumulate it slowly!
The university textbook \"Factory Electrical Control\" is excellent; it explains complex concepts in simple terms and provides detailed descriptions of most common control circuits currently in use – making it suitable for beginners.
Take a look at the second-round image recognition; study the drawings more and ask the teacher questions
It’s generally available in Xinhua Bookstores; “How to Read Electrical Construction Drawings”
First, it is important to understand the legend; once that is understood, one can then examine the wiring connections to identify the circuits, following the direction of current from the power fuse through the windings or indicator lights until reaching the neutral wire. Similar to functions like start/stop control in PLCs. Next, look at the wire numbers and the symbols in the legend.
It’s important to add more logic, otherwise it will become very chaotic.
First, understand the process or control flow; only then can you know what the diagram is referring to. Next, understand the wiring of electrical components, their operating conditions, and relevant protections. Large electrical diagrams are usually divided into multiple pages; it’s necessary to figure out the connection numbers and wire numbers. By then you should be able to understand everything. If PLCs are involved, you also need to examine the programs!
It’s pretty good here: http://www.dlgcs.cn/, you should take a look
