110kV单芯海缆铠装损耗试验研究

20135No．52013ElectricWire＆Cable201310Oct．2013110kV张磊，郑新龙，宣耀伟，章正国，何旭涛316000基于海洋输电实验基地，对110kV单芯海缆铠装损耗进行了试验研究。试验验证了当线芯导体通过大电流时，铅护套及铠装上产生了感应电动势，并且在不同运行方式的损耗测试中证明了铅护套的屏蔽作用。最后通过对比试验，证明了铅包铠装回路串联电阻能减小海缆的损耗。单芯海缆;感应电压;铠装损耗;试验研究TM247.9A1672-6901201305-0022-04ExperimentalStudyontheArmoredLossof110kVSingle-CoreSubmarineCableZHANGLeiZHENGXin-longXUANYao-weiZHANGZheng-guoHEXu-taoZhoushanPowerCompanyofStateGridZhoushan316000ChinaAbstractTheexperimentalstudyonthearmoredlossof110kVsingle-coresubmarinecablewastakenonuponthebaseofmarinetransmissionexperiment．Theexperimentverifiedwhenthecoreconductorhadalargecurrentthein-ducedelectromotiveforcewasgeneratedontheleadsheathandthearmouring．Meanwhilethelosstestindifferentwaysofrunningprovedtheshieldingeffectoftheleadsheath．Finallybycomparingtestitwasprovedthatseriesresistanceinleadcoveredarmoredcircuitcanreducethelossofsubmarinecable．Keywordssingle-coresubmarinecableinducedvoltagearmoredlossexperimentalstudy2013-03-201984－．600316021．0。。1。2-3。4-6。。72.5IEC。245kV12kV2.5。。8。、。1。1。130m3.6m1.2m。9.8℃8.0℃。1。HYJQF41-64/110-1×500195m。7.6mΩ。2。、。。。28.9mΩ69.4mΩ。21AB。1、2100A200AAB3。33.1。。9。us=jωMI1MI。100～600A、1。1、/A/V/V/V1007.196.3766.68020014.1312.8712.9530021.3219.2919.7140028.6225.9326.7850036.1132.8533.8860043.7139.8441.0611U=0．0688IU=0．0668IU=0．0513I。M=0.2191mHM=0.2126mHM=0.1633mH。AB。MMM。、、。3.2。100A2。2100A/W/A/A/A/A、138101.2－－－、25699.688.151.436.727099.4－76.9－39399.4－－67.3P=I2RR=7．6mΩP76W。200A3。304W。28.9mΩ69.4mΩ。、100AP=76WP=93．47WP=76．35WP=10．18W·32·20135No．52013ElectricWire＆Cable201310Oct．20133200A/W/A/A/A/A、590199－－－、1034199.8174.8101.673.21090199.6－152.6－1623201.7－－135.9200AP=304WP=371.86WP=298.32WP=59.82W。PP。1、2。、。、。。2。U·sI·c90°U·sRcLc2I·sU·sI·s+I·cI·c。I·cI·s+I·c。10。。3.3R=1.32ΩL=400mHZ=1.35Ω。4。4I/AP/WS/VAQ/VarU/VPFI/AI/AI/A52.570109822.0590.64847.217.330.7101.42644053053.990.65189.933.857.9151.959891468860.654133.951.385.4199.11028157511927.90.655175.267.8111.3248.81605246118639.860.652217.884138.7297.722933504266611.780.652260100.8166.051.4472242194.330.209550.36100.61898528308.460.22010.619.730.92149.34281879182812.60.22815.7214.431.58198.77813336325016.820.23620.819.162.3248.212505230506021.080.23926.224.042.89297.118707550731025.340.2531.0329.144.120.5R4IPABSABQABUABPFP/S。1。。。50A0.5R32.8%300A0.5R18.4%。3·42·20135No．52013ElectricWire＆Cable201310Oct．2013。3。2P=Scosφ0.6520.5R0.23。30.5R88%4。44、。4HYJQF41-64/110-1×500。———。1、、。2、、。3。1．35kVJ．2008378-79．2．110kVXLPEJ．20051170-71．3．110kVJ．2005816-17．4．J．2002218-19．5．J．2005225-26．6．J．20071050-51．7BremnesJ．JEvensetGStolanR．Powerlossandinductanceofsteelarmoredmulti-corecablescomparisonofIECvalueswith“25D”FEAresultsandmeasurementsC//CIGRE2010Paris．8．J．2005222-24．9．M．1995．10．10kVJ．20025檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨檨殎殎殎殎30-31．欢迎广大读者为本刊撰写稿件!欢迎广大读者给本刊提出建议!欢迎相关企业在本刊登载广告!·52·20135No．52013ElectricWire＆Cable201310Oct．2013
