Features: To meet the needs of vocational skill assessment, safe operation, operational techniques, on-site work, and daily tasks for power supply and distribution personnel and agricultural power grid workers. Based on the "National Vocational Skill Assessment Standards for the Power Industry" (Distribution Line Worker and Agricultural Power Distribution Business Worker) and relevant codes and standards, and combined with the actual production conditions of power supply and agricultural power, the "Training Textbook for Distribution Technology and Techniques" was organized and compiled. This textbook presents the vocational skill requirements in a concise and clear manner, facilitating training and assessment for power supply and agricultural power personnel, enhancing safe operation and technical proficiency, and improving the overall quality of distribution personnel. This book is the "Distribution Technology and Techniques Training Textbook" (Distribution Line) volume, comprising 13 chapters and an appendix. The specific content includes: Power Systems and Power Networks, Medium and Low Voltage Towers and Their Accessories, Estimation of Tower Body Quality, Anti-Corrosion and Conductor Arrangement and Tower Types, Conductor Performance and Section Selection, Classification of Insulated Conductors, Material Properties, Structural Installation, Lightning Protection and Grounding, Calculation of Overhead Conductor Sag and Pole Mechanical Calculations, Composition and Function of Pulling Wires, Section and Diameter Calculation, Installation Requirements, Pulling Wire Plate Selection and Depth, Distribution Line Operation Inspection Standards, Testing and Inspection, Operation Management, Fault Analysis, Anti-Contamination Arcing, Phase Rechecking, Corona and Vibration, Common Distribution Transformers' Polarity, Construction Parameters, Connection Groups, Non-crystalline Alloy, Underground, Lightning Protection, Dry Type, On-load Voltage Regulation, Transformer Selection and Installation, Operation Protection, Power Outage Operation, Tap Adjustment, Minor Maintenance, Load Control, Transformer Platforms, and Drop-out Fuses, Reactive Power Compensation and Loss Reduction Methods, Capacitor Compensation, Parameter Wiring, Installation Acceptance, Protection Operation, Overvoltage Protection and Lightning Protection Wiring, Current and Voltage, Insulation Resistance, Grounding Resistance, Multimeters, Current and Voltage Transformers, Road Lighting, Ballasts, Lamps, Switch Control, and Operation, followed by parameter tables for common distribution line tower types, pole categories, conductor and cable categories, pulling wire categories, insulator categories, hardware categories, transformer categories, switch and fuse categories, lightning arrester categories, conductor sag tables, and standard design, construction, operation, and equipment for common distribution lines. This book can serve as a vocational skill, job skill, and operational technique training textbook for medium and low voltage distribution line workers, agricultural power distribution business workers, young workers with junior high school or higher education, auxiliary transfer to main business personnel, temporary workers, rural migrant workers, and demobilized military personnel in production roles. It can also be used as a reference textbook for distribution line professionals and management personnel.
