摘要本说明书以220kv富蕴县钟山变电站为例，论述了电力系统中变电站电气部分在整个建设投产过程中，对主要电气设备的调试的过程，全站工程调试任务包括全站一次设备元件试验；保护装置校验；二次回路检查及保护联动调试。本设计书则主要侧重于主要电气设备的高压试验部分的理论和实际操作做以论述。限于毕业设计的具体要求和设计时间的限制，本毕业设计只对变电站电气主要电气设备的高压试验部分理论和操作的设计，而对保护装置校验、二次回路检查及保护联动部分并没有涉及，这有待于在今后的学习和工作中进行研究。关键词：变电站电气设备电气调试一次设备元件试验ABSTRACTThisinstructiontoFuYunXianareaofzhongshan220kvaltaysubstationasanexample,discussestheelectricalpowersysteminthewholesubstationconstructionproductionprocess,themainelectricalequipmentdebuggingprocess,electronicengineeringsurveyingtaskincludeequipmentdebuggingdevicestest,Protectiondevicecalibration,Thesecondarycircuitinspectionandprotectlinkagetesting.Thisdesignismainlyfocusedonmainelectricalequipmenthigh-voltagetestparttheoryandpracticaloperationwithpaper.Limitationofgraduationdesignrequirementsanddesignofthetimelimit,thedesignofmainelectricsubstationonlyelectricalequipmentofhigh-voltagetestpartofthedesigntheoryandoperationofprotectiondevice,andthesecondarycircuitcalibration,inspectionandprotectlinkagesection,thisdoesnotinvolveinfuturestudyandwork.KEYWORDS:Substation，Electricalequipment，Electricalequipmentdebugging，Equipmentdebuggingdevicestest。目录总述.......................................................................................................1㈠变电站的介绍.................................................................................1㈡阿勒泰市富蕴县钟山变电站简介.................................................2㈢变电站电气调试流程.....................................................................3第一部分：试验理论部分................................................................6第一章：绝缘电阻试验.....................................................................6第一节：基本概念及注意事项.........................................................6第二节：测量结果分析判断.............................................................6第二章：吸收比和极化指数的测试................................................7第三章：泄露电流的测量................................................................8第一节：基本定义及注意事项.........................................................8第二节：试验结果的分析判断.........................................................9第四章：介质损失角正切（tan）的测量....................................9第一节：基本定义及注意事项.........................................................9第二节：测量结果分析判断...........................................................11第五章：局部放电的测量..............................................................12第一节：基本定义及注意事项.......................................................12第二节：试验结果分析判断...........................................................14第六章：工频耐压试验...................................................................14第一节：基本定义及注意事项.......................................................14第七章：直流耐压试验...................................................................15第一节：基本定义...........................................................................15第八章：冲击耐压试验...................................................................17第一节：基本定义...........................................................................17第二部分：试验操作部分..............................................................20第一章：主变试验...........................................................................20第一节：试验工序...........................................................................20第二节：试验方法...........................................................................20第二章母线耐压试验.....................................................................25第一节：试验步骤及要求...............................................................25第二节：实验设备及注意事项.......................................................26第三章：真空断路器试验..............................................................26第一节：施工工序...........................................................................26第二节：试验方法...........................................................................27第三节：试验时的注意事项...........................................................29第四章：互感器试验.......................................................................29第一节：工作流程...........................................................................29第二节：试验步骤及要求...............................................................30第三节：注意事项：.......................................................................31第五章：避雷器试验.......................................................................32第一节：试验工序...........................................................................32第二节：试验方法...........................................................................32第六章：电缆试验...........................................................................34第一节：试验工序...........................................................................35第二节：测量方法...........................................................................35第三节：测量结果分析判断...........................................................38第七章：电容器试验.......................................................................39第一节：试验工序和试验方法.......................................................39第二节：测量方法...........................................................................39第八章：套管试验..........................
