AbstractElectrical design of substation high-voltage switchgearAbstract This article on the substation of high voltage switchgear related to the electrical knowledgeand substation electrical design for some introduction.The first chapter introduces the power systemknowledge,including the power system a wiring,grounding system,new energy and high voltageswitchgear five aspects.Which the characteristics of a power system wiring and the use of a detaileddescription of the occasion.At the same time for the development of new energy status,domestic andinternational comparison,as well as installed capacity,technological progress also have a certaindescription.High-voltage switchgear aspects of the graduation design is the main part of this,not onlyfrom the development of high-voltage switchgear at home and abroad,as well as technologicalprogress(miniaturization intelligent)made an analysis,while the commonly used high-voltageswitchgear types,Product technical parameters,features,etc.also have a more detailed description.The second chapter to introduce electrical components,including transformers,circuit breakers,current transformers,voltage transformers,computer protection devices and switch status indicatorand so on.And the type of product type,technical parameters,product features made a detaileddescription.For what kind of occasions should choose what type of electrical components have areference role.The last chapter is the electrical engineering design,on the one hand gives acomplete electrical design drawings,including a map,quadratic map,terminal diagram andequipment material table,on the other hand gives a loop and secondary circuit principle analysis.Key words:Power Systems High voltage switchgear Breaker Electrical Design
