压力释放阀PRESSURERELEASEVALVE使用说明书OPERATIONINSTRUCTION沈阳明远电器设备有限公司SHENYANGMINGYUANELECTRICEQUIPMENTCO.,Ltd.1本说明书适用于我公司生产的系列变压器用压力释放阀,阐述其用途、性能、规格、技术参数、使用及安装,供用户参考。TheOperationInstructionisapplicabletopressurereleasevalveofaseriesoftransformersmanufacturedbyourcompany,indicatingitsapplication,performances,specifications,technicalparameters,usageandinstallationforuses’reference.1.压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等,用来保护油箱。当油浸式变压器在运行中出现故障时,由于线圈过热,使一部分变压器油汽化,变压器油箱中压力迅速增加,这时压力释放阀在2ms内迅速动作,释放压力,保护油箱不致变形或爆裂。油箱内的压力再升高而达到开启压力时,压力释放阀应再次动作,直到油箱内的压力降到正常值。由于压力释放阀动作后能可靠关闭,油箱外的水和空气不能进入油箱,变压器内部不会受大气污染。1.ApplicationandperformancePressurereleasevalvesplayavitalroleintheprotectionofoil-immersedelectricalequipments,suchastransformers,highvoltageswitchgears,capacitorandonloadtap-changers,etc.Thisdevicecanpreventtheoil-immersedelectricalequipmentfromdeformationorrupture.Shouldafaultoccurinsuchelectricalequipment,fromdeformationofrupture?Shouldafaultoccurringinsuchelectricalequipment,theyareinstantaneouslyvaporizetheoilcausingextremelyrapidbuild-upofgaseouspressure?Ifmountingthistypepressurereleasedeviceontheoil-tank,whenthepressurereachestoitsopeningpressure,itopensautomaticallywithin2msandrelievesthepressure.2.型号、规格及基本参数Type,specificationandtechnicalparameters2.1型号的含义MeaningoftypeYSF□—□/□□□特殊环境代号(Specialenvironment)带机械信号标“J”(“J”:mechanicalsignal)带信号开关标“K”(“K”:electricalsignal)两者都带标“KJ”(“KJ”:Bothwithsignal)喷油有效口径(Caliberofoil-gushingtube)mm开启压力(Openingpressure)kPa设计序号(Designserialnumber)阀(valve)释放(release)压力(pressure)注:特殊环境代号note:specialenvironment:TA:干热带地区drytropicTH:湿热带地区humidtropicT:干、湿热带地区dry、humidtropic例:YSF16-55/130KKJT开启压力为55kPa,喷油口径为φ130mm,带电信号、机械信号。适用于干、湿热带地区的压力释放阀。Example:YSF16-55/130KKJTinwhich,openingpressureis55kPa,caliberofoil-gushingtubeisφ130mmandflangeerection,withelectricalandmechanicalsignalandwaterproof,useindry、humid1tropic。22.2规格(见表1)Specifications(giveninTableⅠ)表1TableⅠ喷油有效口径effectivecaliber(mm)开启压力openingpressure(Kpa)φ2015,25,35,55φ25φ50φ8035,55,70,85φ1302.3基本参数(见表2)Basictechnicaldata(giveninTableⅡ)表2单位:kPaTableⅡunit:kPa开启压力openingpressure152535557085开启压力偏差deviationofopeningpressure±5关闭压力≥closingpressure813.51929.537.545.5密封压力≥sealpressure915213342513.安装尺寸Installationdimensions3.1法兰安装尺寸(见表3)Flangeinstallationdimensions(giveninTableⅢ)表3单位mmTableⅢunit:mm喷油有效口径caliberofoil-gushingtubeφ25φ50φ80φ130连接管内径Internaldiameterofconnectiontubeφ45φ80φ130φ165安装法兰螺孔中心距centerpointdistantofinstallationflangeφ90φ130φ1706、8型φ23510、12型φ240螺栓直径×数量diameterofbolt×unitsM10×3M12×4M12×66、8型M16Χ612、16型M20Χ83.2螺纹安装尺寸(见表4)Screwinstallationdimensions(giveninTableⅣ)表4单位mmTableⅣunit:mm有效喷油口径caliberofoil-gushingφ20φ25φ50箱盖开孔holeintanklidφ32φ40φ67螺纹×螺距thread×stepM...
