N***LFUltra-lowFrequencyHighVoltageGenerator南澳电气N***LF超低频高压发生器试验装置产品简介南澳电气N***LF超低频高压发生器试验装置结合了现代数字变频***技术，采用微机控制，升压、***、测量、保护完全自动化，并且在自动升压过程中能进行人工干预。由于全电子化，所以体积小重量轻、大屏幕液晶显示，清晰直观、打印机输出试验报告。设计指标完全符合《电力设备专用测试仪器通用技术条件，第4部分：超低频高压发生器通用技术条件》电力行业标准，使用十分方便。现在国内外均采用机械式的办法进行调制和解调产生超低频信号，所以存在正弦波波形不标准，测量误差大，高压部分有火花放电，设备笨重，而且正弦波的二，四象限还需要大功率高压电阻进行放电整形，所以设备的整体功耗较大。均能克服这样一些不足之处。南澳电气N***LF超低频高压发生器试验装置产品别名超低频高压发生器，N***LF超低频高压发生器，程控超低频高压发生器，超低频交流高压试验装置，超低频耐压试验装置,超低频发生器南澳电气N***LF超低频高压发生器试验装置产品特性1.电流、电压数据均直接通过高压侧采样获得，所以数据真实、准确。2.过压保护：当输出超过所设定的限压值时，仪器将停机保护，动作时间小于２０ms。3.过流保护：设计为高低压双重保护，高压侧可按设定值进行***停机保护；低压侧的电流超过额定电流时将进行停机保护，动作时间都小于２０ms。4.高压输出保护电阻设计在升压体内，所以外面不需另接保护电阻。5.由于采用了高低压闭环负反馈控制电路，所以输出无容升效应。南澳电气N***LF超低频高压发生器试验装置产品参数1、输出额定电压：略2、输出频率：0.1Hz、0.05Hz、0.02Hz。3、带载能力：参见下表0.1Hz***大1.1μF(理论值，现场电缆长度为1－3公里）0.05Hz***大2.2μF(理论值，现场电缆长度为1－3公里）0.02Hz***大5.5μF(理论值，现场电缆长度为1－3公里）4、测量精度：满量程的３%5、电压正，负峰值误差：≤３%6、电压波形失真度：≤５％7、使用条件：户内、户外；温度：-10℃∽+40℃；湿度：≤85％RH8、电源：交流50Hz，220V&plu***n;5%南澳电气N***LF超低频高压发生器试验装置注意事项1、N***LF超低频高压发生器所配升压器不得作它用。2、机内带电,切勿自行拆机修理，以免发生意外。仪器有故障，应与南澳电气联系修理。3、关机后应用放***对试品进行充分放电,再拆线。4、开机前应用放***对试品进行充分放电。5、每次启动升压前应用放***对试品进行充分放电。ProductintroductionN***LFUltra-lowFrequencyHighVoltageGeneratorcombinesthemoderndigitalfrequencyadvancedtechnology,usescomputercontrol,boost,***andmeasurement,automaticallyfullprotection,andintheprocesscanautomaticallyboostcancarryamanualinterventionintheprocessofautomaticallyboosting.Sinceallwithelectronic,is***allandlight,large-screenLCDdisplayed,clearandintuitive,printerouttestingreport.TheDesignindicatorsisinfullcompliance"specialtestequipmentelectricalequipmentGeneraltechnicalconditi***,Part4:ultra-lowfrequencyhighvoltagegeneratorgeneraltechnicalconditi***"powerindustrystandard,easytouse.NowadayshomeandabroadadoptedmechanicalapproachtoproduceN***LFmodulationanddemodulationtogeneratesignal,sothereisnostandardsinew***eform,andmeasurementerrorislarge,high-voltagepartwithasparkdischarge,he***yequipment,andthetwoandfour-quadrantsofsinew***e,needlargepowerhighvoltageresistancetodischargeandsharp,thetotaltotalpowerc***umptionisverylarge.TheN***LFUltra-lowFrequencyHighVoltageGeneratorcanovercometheseshortcomings.AlsocallednameN***LFhighvoltagegenerator,N***LFhighvoltagegenerator,programmableN***LFfrequencyhighvoltagegenerator,N***LFfrequencyAChighvoltagetestingequipment,N***LFfrequencywithstandtestingequipment,N***LFfrequencygenerator.TheCharacteristicsoftheproducts1,Advancedtechnology:Usingdigitalfrequencyconversiontechnology,microcomputercontrolled,boost,***,measurement,protectionandfullautomatedtestingprocess2,Easytooperate:Wiringissimple,easytomoveandoperation3,Comprehensiveprotection:Multipleprotection(overloadprotection,highandlowvoltageovercurrentprotection),promptaction(actiontime≤20ms),isasafeandreliableinstrument4,Safeandreliable:thecontrollerandhigh-voltagegeneratorvoltageconnectionvialowvoltage,photoelectriccontrol,safetyandreliability.5,Usingahigh-pressureclosed-loopnegativefeedbackcontrolcircuit,theoutputcapacitywithoutcapacityboosteffect6,Fullyequipped:largeLCDdisplay,automaticstorage,automaticprinting7,Largetestrange:0.1Hz,0.05Hzand0.02Hzmulti-frequencyselection,largetestingrange8,***allinsize,lightinweight:isconducivetooutdoorworkTheparametersoftheproducts1,Theoutputvoltage:seetablebelow2,Theoutputfrequency:0.1Hz,0.05Hz,0.01Hz.3,Loadcapacity:seetable0.1HzMaximum1.1μF(theoreticalvalue,on-sitecablelength1-3km)0.05HzMaximum2.2μF(theoreticalvalue,on-sitecablelength1-3km)0.02HzMaximum5.5μF(theoreticalvalue,on-sitecablelength1-3km)4,Accuracy:3%offullscale5,Thevoltagepositiveandnegativepeakerror:≤3%offullscale6,Thevoltagew***eformdistortion:≤5%7,Usageconditi***:indoor,outdoor;Temperature:-10℃∽+40℃;Humidity:≤85%RH8,PowerSupply:AC50Hz,220V&plu***n;5%Attentionshouldtake1,N***LFUltra-lowFrequencyHighVoltageGeneratorareequippedwithabooster,cannotuseforotherways.2,Ifthemachinecharged,donottrytodisassembleandrepair,to***oidaccidents.Ifthe3,Aftershutuptheinstrument,pleaseusedischargingrodtodischargethetestedobjectfully,thendi***antlethewire.4,Beforeturnontheinstrument,pleaseusethedischargingrodtodischargethetestedobjectfully.5,Beforeturnonandboost,pleaseusethedischargingrodtodischargethetestedobjectfully.)
