Analysis of the Main Connection Scheme for Multi-Power Supply and Distribution System
Based on current industry regulations and national standard drawings,this article begins with the functional classification and terminology definition of power supply systems.Through in-depth analysis of specific provisions in regulatory documents and practical examples in drawings,it explores the suitability of various main connection schemes in multi-power supply and distribution systems.Combining theoretical analysis with practical cases,the article aims to correct common cognitive biases and errors in electrical design,enhance the safety and stability of the system,and provide electrical engineers with both theoretical and practical references.The article focuses on defining and distinguishing between normal power sources,standby power sources,and emergency power sources,as well as how to accurately apply these power sources in design to meet the needs of different load levels,especially the power supply assurance for critical loads.
