Features: This atlas is compiled based on a comprehensive summary of the technologies and techniques for the design, installation, acceptance, operation, and maintenance of urban and rural power distribution station engineering, especially the new technologies, equipment, and processes that have emerged in recent years. It adheres to the requirements of newly issued standards, regulations, and procedures, presented in a concise graphical format. The content of this atlas primarily includes electrical connection diagrams, electrical layout plans, civil engineering layout plans, installation diagrams, and incoming/outgoing switchgear connection diagrams for 10kV dual-power dual-bus switch stations, single-power single-bus switch stations, dual-power single-bus switch stations, public single (dual) 1-unit transformer terminal distribution stations and intermediate distribution stations, packaged substations, user-owned distribution substations with capacities below 800kVA, and user-owned distribution substations with capacities above 800kVA (tray-type switchgear, fixed switchgear). Additionally, it covers 10kV multi-power electrical connection diagrams and low-voltage distribution connection diagrams, secondary circuit wiring diagrams, schematic diagrams, protection function diagrams, and system diagrams for DC power supplies and control power supplies for 10kV single (dual) power sources with single (multiple) transformers (or main supply, backup supply), as well as electrical connection diagrams, layout plans, and examples of 10kV three main supply and one backup power supply systems, incoming/outgoing distribution cabinets, high-rise electrical room distribution cabinets, busbar layout and connection, switchgear incoming/outgoing connections. Examples of 10kV power cables and their terminal heads, intermediate heads, path diagrams, installation diagrams, and installation illustrations are also provided. Device diagrams, installation diagrams, and layout plans for 10kV concrete poles, steel towers, steel pipe poles (straight poles, angle poles, tension poles, branch poles, terminal poles, transformer platforms, switchgear platforms, grounding devices) are included. Five 10kV distribution station engineering projects are listed as examples, including the design, processing, and installation diagrams for user-owned single 500kVA oil-immersed transformers, user-owned single 630kVA dry-type transformers, public dual 1000kVA and user-owned single 500kVA dry-type transformers, public dual 630kVA and user-owned single 400kVA dry-type transformers, user-owned dual 1250kVA and dual 2000kVA transformers, and public single 630kVA and user-owned single 1000kVA transformers. After the main chapters, technical parameters and reference prices for distribution transformers (10kV and below), high/low-voltage switchgear, circuit breakers, load switches, fuses, contactors, knife switches, busbars, power cables, lightning arresters, insulators, hot-rolled steel, concrete poles, and DC control panels are listed for direct selection by electrical design and construction personnel in distribution engineering. This atlas is concise, easy to use, and serves as a reference book for professionals, technicians, workers, and cadres engaged in distribution station design, processing, installation, acceptance, operation, and management, as well as electricians from power supply companies, industrial enterprises, rural power supply stations, and construction companies. It can also be used as supplementary teaching material for power industry schools and industrial vocational schools.
