简介:本文档为《变压器油色谱分析doc》,可适用于综合领域

变压器油色谱分析方法概述用气相色谱法测定绝缘油中溶解气体的组分含量是发供电企业判断运行中的充油电力设备是否存在潜伏性的过热、放电等故障以保障电网安全有效运行的有效手段。也是充油电气设备制造厂家对其设备进行出厂检验的必要手段。GCSD变压器油色谱分析系统采用一次进样、双柱并联、一次分流的三检测器流程配TCD检测器和两个FID检测器其中H和O通过TCD检测烃类气体(甲烷、乙烯、乙烷、乙炔)通过FID检测CO、CO通过FID检测克服了大量CO、CO对烃类气体的影响特别是乙炔的影响。执行标准:GBT《绝缘油中溶解气体组分含量的气相色谱测定法》GBT《变压器油中溶解气体分析和判断导则》DLT《变压器油中溶解气体分析和判断导则》气路系统流程图:性能指标:()最小检测量:一次进样进样量为mL时的最小检测浓度:溶解气体的分析(uLL)HCOCOCHCHCHCH()定性重复性:偏差,()定量重复性:偏差,()热导检测器(TCD)◎采用半扩散式结构◎电源采用恒流控制方式◎敏感度:Smvmlmg(正十六烷异幸烷)◎基线噪音:μv◎基线漂移:μvmin◎线性:◎载气流速稳定性:。()火焰离子化检测器(FID)◎收集极采用圆筒型结构石英喷口◎检测限:×gs(正十六烷异幸烷)◎基线噪声:×A◎基线漂移:×Amin◎线性:◎自动点火◎稳定时间min主要特点主机介绍GCSD变压器油色谱分析系统是上海荆和分析仪器有限公司最新推出的一款新型全微机控制气相色谱仪。仪器充分吸收了国外同类产品的先进技术大量采用进口元件使GC的稳定性、可靠性以及灵敏度和重复性蓖美进口同类型产品并且在结构上更加简洁合理人性化的中文菜单式操作精美的外观设计让色谱分析工作者使用的更加自信。主要技术特点:(高精度、稳定可靠的温度控制系统:◎仪器主控电路采用了功能先进的微处理器大规模的集成电路先进的贴片封装使电路结构紧密而稳定大容量的FLASH及EEPROM存储器的采用使数据的保存更加可靠。同时一体化的主控电路板设计提高了仪器的抗干扰性和可靠性。◎温度控制电路采用微处理器控制五路高精度的控制系统其中柱箱可实现五阶程序升温保证了客户进行宽沸程复杂样品的分析各被控加热区的温度控制精度优于(时测)。◎柱箱具有双重的超温保护功能其中任一加热区温度超过设定极限仪器均会自动保护停机既保证了安全又方便你的维修。◎智能化的后开门技术保证仪器的柱箱温lineofthebusthroughthelistofmadeamoredetailedprovisions,applymoreoperationalSevenisincreasedthearticle,inviolationoftherelevantprovisionsofthe,toparticipateinpublicfundstopayfordinner,highconsumptionofentertainment,fitnessactivitiesandpublicfundstobuygift,sendgiftstomaketheprovisionsofthedispositionOntheviolationofthecentralprovisionsofthespiritoftheeight,inadditionto><newregulationsinto"violationofhonestyandselfdiscipline"misconductoutside,isdifferentwiththeoriginal<Regulations>,revised<rule>clearlydefinednotonlytodispositionofthedirectlyresponsiblepersons,butalsodisposeofcollarGuideresponsibilities()increasedtradingrights,useofauthorityorpositioninfluenceasrelativesandclosetoprofitviolationofthetermsofthe<NewRegulations>absorption<cleanpoliticsseveralguidelines>therelevantprovisionsspirit,increasethe"negativelist,includingtradingrights,thefunctionsandpowersordutiesofinfluenceasrelativesandstaffaroundprofitIncreaseArticle"mutualuseofofficeorauthorityringforeachotherandtheirspouses,childrenandtheirspousesandotherrelatives,aroundpersonnelandotherspecificrelationshipbetweenthepeopletoseekbenefitsengageintradingrights,givenawarningorseriouswarningSanctionsifthecircumstancesarerelativelyserious,givingremovedfromorplacedonprobationwithinthepartypostifthecircumstancesareserious,shallbeexpelledfromthepartyIncreaseArticle"connivance,acquiescencetothespouse,childrenandspouseetcrelativesandstaffaroundtheeffectofPartymembersandcadrespersonalauthorityorpositionforpersonalgain,ifthecircumstancesarerelativelyminor,givenawarningoraseriouswarningifthecircumstancesarerelativelyserious,givingremovedfromorplacedonprobationwithinthepartypostifthecircumstancesareserious,thegivenExpelledfromthepartyPartymembersandcadresofthespouses,childrenandtheirspousesdoestheactualworkandgetsalaryoralthoughtheactualworkbuttoreceivesignificantlybeyondthesameranksalarystandard,Partymembersandcadresinformedfailstocorrect,inaccordancewiththeprovisionsoftheprecedingparagraph"()aboutthegifts,giftsmisconductfromhandlingpracticesinrecentyears,engagedinofficialcadresreceivedgifts,giftsproblemsmoreprominentThishasseriouslyaffectedtheimageofPartymembersandcadres,damagedtherelationsbetweenthepartyandthemasses,andisahotbedofcorruption,isreallynecessaryforthiskindofbehaviortobedisciplined<rule>noonacceptinggifts,gifts,Cardconsumptionbehaviortoengageinsimple"onesizefitsall",butthedifferencebetweenthedifferentseparatelyOneisinaccordancewiththeprovisionsofArticle,acceptingmayaffecttheimpartialenforcementoftheofficialgifts,gifts,consumercardstodependingontheseriousnessofthecaseshallbegivendisciplinarysanctionsThatistosay,formayaffectthefairexecutionofbusinessgifts,gifts,consumercardsarenotallowedtoacceptisinaccordancewiththeprovisionsofArticle,acceptingwassignificantlyhigherthannormalceremonyisstillexchangesofgifts,gifts,consumercardtodisciplinaryactionThisisnewregulationsthatdailylifeispurelyreciprocity,acceptingthesamething,boys,fellowfriendsgifts,gifts,shoppingcards,althoughandfairexecutionofbusinesshasnothingtodo,alsowanttoasthecaseshallbedealtwith,thesituationisobviouslybeyondnormalreciprocity"Thesocalled"reciprocity",oneisemphasizesthereciprocalinprotocolInotherwordsisyoutomehow,Itoyouhow,notonlydoesnotgoThesecondistosignificantlyexceededthenormallocaleconomylevel,customsandhabits,economiccapacityofindividualgifts,giftvalueSpecificsanctionstoaccordingtotheprocessingofavarietyoffactorstoconsider,asappropriateThethirdistherootaccordingtotheprovisionsofArticle,"toEngagedinpublicservicepersonnelandtheirspousesandchildren,children'sspousesandotherrelativesandotherspecificrelationshippresentedMingXianchaonormalreciprocityofgifts,gifts,consumercard,ifthecircumstancesarerelativelyserious,givenawarninguntilprobation"Inaccordancewiththeaboveprovisions,giftgivingsignificantlybeyondthenormalreciprocity,giverconstitutethediscipline()onillegaltradingofstocksorofotherregulationsofsecuritiesinvestment<>Articleisengagedinpunishmentregulationofcampandactivityinviolationoftherelevantprovisions
