Features: Diagrams are the language of engineers, and diagrams possess linguistic attributes: vocabulary, grammar, and writing styles. This book is written by the author based on over two decades of experience in electrical teaching, following the principle that diagrams have linguistic attributes. The book first introduces the basic elements of diagrams—the structure, working principles, models, and corresponding graphical and textual symbols of common electrical components. It then explains the drafting rules and representation methods of electrical diagrams. Starting from Chapter 3, it details the reading methods for specific electrical diagrams in various electrical engineering fields. This book does not focus solely on diagrams but emphasizes the reading methods of electrical diagrams and the principles of various electrical devices, enabling readers to achieve the goal of learning by analogy. The book provides specific analyses of electrical diagrams for various electrical devices, making it suitable for self-study by young electricians with some electrical knowledge. It can also serve as a textbook and teaching reference for relevant majors in colleges and universities, as well as a reference for electrical engineering professionals. For students from non-electrical disciplines, it is recommended to focus on reading Chapter 1, Chapter 2, and control circuit diagrams related to their majors; for students in electrical disciplines, it is recommended to focus on reading Chapter 2 and the specific electrical diagrams of various projects, with an emphasis on mastering their analytical methods; for young electricians, it is recommended to read Chapter 1, Chapter 2, and electrical diagrams related to their professional fields.
