Features: "The Training Textbook for Power Supply and Distribution Workers Technicians" is a set of job skills training and vocational skill assessment textbooks compiled according to the requirements for vocational technicians (senior technicians) personnel as specified in national standards, power industry standards, and national vocational skill assessment specifications (power industry). It is strictly aligned with and combines the knowledge, skill requirements, and assessment content that vocational technicians should possess. At the same time, it is linked with "The National Power Supply and Distribution Workers Skill Training Textbook (Intermediate, Advanced, Senior)", emphasizing the principle of prioritizing skills while knowledge serves skills and meets skill needs. When describing skill requirements, it often adopts the form of illustrative examples, aiming to provide a set of textbooks for technician job skills training and vocational skill assessment for production personnel in power supply and distribution enterprises across the country. This volume is one of "The Training Textbook for Power Supply and Distribution Workers Technicians," consisting of ten chapters, mainly including two parts: knowledge requirements and skill requirements for substation maintenance workers and technicians. The first chapter briefly introduces basic knowledge such as electrical principles, power system relay protection, overvoltage, grounding, and pollution flash prevention. The remaining chapters systematically describe the working principles, basic structures, maintenance, and commissioning methods of main equipment in substations, including main transformers, on-load tap changers, current and voltage transformers, oil circuit breakers, SF6 circuit breakers, vacuum circuit breakers, disconnectors, busbars, and power cables. This textbook has strong practicality, enabling substation maintenance technicians to comprehensively master various professional skills and guide substation equipment maintenance work. This set of textbooks is the designated material for job skills training and vocational skill assessment for technician personnel in national power supply and distribution enterprises. This volume is a training textbook for substation maintenance technicians and can also serve as a reference for advanced workers, senior technicians, technical personnel, and management personnel in substation maintenance.
