Features: This book is written based on the author's extensive teaching experience and recent field training work for equipment introduction, combined with the issuance of the new national standards for electrical drawing. The book is divided into two parts, with a total of nine chapters. The first part systematically elaborates on the basic knowledge of electrical reading, focusing on the new symbols, codes, markings, rules, and layout representations related to secondary circuit diagrams, along with reading methods and examples. The second part lists various new secondary circuit diagram examples for different primary equipment, referencing the drafting styles of some large domestic and international electrical companies, along with the information they contain. This book adheres to the new national standards and equivalently introduces the new IEC international standards, featuring both Chinese and foreign examples, aligning with international standards. The text is concise and easy to understand, with a comparison between the old and new, progressing from simple to complex. It serves as both an introductory guide for those learning new secondary circuit diagrams and a reference for reading imported drawings, catering to different levels of requirements. The appendix compiles relevant materials, including the new national standards listed and those permitted for compatibility, serving as a concise toolbook for reading new secondary circuit diagrams. This book is suitable for electrical technical personnel engaged in design, manufacturing, installation, commissioning, operation, and maintenance in power systems and industrial and mining enterprises, as well as a teaching reference for universities, colleges, and vocational and technical training institutions.
