ABBEI813F3BDH000022R110KV单项（俩相接地属于短路，早跳闸了）接地相对比较常见，接地故障原因很多。如果是初学变电站运行者，应该补充学习电工基础知识，至少要知道（短路断路通路）还有（电压电流电阻）的关系等。高压线一般就三条线，（ABC）三相对地一般是绝缘的（大地也是导电的）只要有其中任意一相接触了大地就称单项接地了。它并不影响短期运行，只是一些绝缘体受到一定的考验。就是说10KV系统所有的绝缘体（支持导线的瓷瓶，避雷器，线圈等）由原来承受的6KV相电压变为10KV线电压，这样时间长了很容易使绝缘体击穿损坏（考虑到设备的经济，设备的灵巧等，绝缘体不能够做很大）。所有一般规定在2小时内处理接地事故。这里需要说明电压互感器的作用：显示电源线电压和相电压，相电压尤其检测10KV系统接地情况。线电压用于计量和保护方面。电压互感器一次侧和二次侧分别装设熔断器和空气开关作为本体保护（电压互感器不能短路）。所以熔断器有时候熔断后一相电压很低，其他俩相正常。（熔断器一般在PT一次侧安装）无论是接地或者断线都要去观察相电压的值。我们要经常去现场观察设备各个部分的构造及工作原理，同时要看懂二次设备图纸，变电站的图纸有几个去翻？只有上级***和站长检修人员去翻或者技术员工程师去翻。规程规定值班人应该读懂图纸，懂了图纸才能知道设备原理，知道了设备原理才能处理事故，如果不知道设备工作原理，怎么能够判断处理事故？变电站10KV接地系统接地原因也多了。常见电缆故障***多，其次瓷瓶击穿。避雷器击穿，导线落地，雷击可能造成瞬间接地或者***性接地。1793-IE4SP081000000GG(含电源IPM02）P0914SVP0926EQP0973JPR2600D1746-IB16UGQMEM-01SNQ22503956-62DR2-04ACIC200MDL940EIC695ETM001IC695PBM300IC697ALG320IC697BEM713IC697BEM733IC697MDL750FW-V10-3.0K57160001-AAADSDI110ADSDO11057160001-K22D-D017N10422F-D6PON10322P-D142A103P0916JP8753ESTC-FTEB011756-ENBT23302330AMSR138DPAT-034-1024A06B-0227-B101A06B-0227-B101B26003510***B-600B1775T-PMPP-17001C31129G03/1C31132G011C31224G01/1C31227G011C31234G01/1C31238H015X00070G04/1C31116G045X00119G01/5X00121G01卡槽UZBA-B1771SC-0MI16DSDP150ACS510-01-157A-4DCS800-S01-1500-05DCS800-S02-0025-04DCS800-S02-0450-041756-PB7257***04C2711-K10C8PCR-1820140ACI03000140ACO13000140CPS11420140CPU67160140CRA93200140CRP93200140DDI84100140DDO84300140EHC20200140NOE77101140XBP00600140XBP01600140XTS00200879DEX-G1140CPU671607兆存储卡UNITYPROABL7RP2405P0914SVP0926EQP0973JPPK564-NA-A33PM450CLA1203HAC033163-0013HAC033182-0013HAC033207-0016***6643-0CD01-1AX16SL3255-0AA00-4BA1IC693CPU374A03B-0807-C154KUAX6801V.24ACS800-01-0025-3+P901ACS800-01-0030-3+P901ACS800-01-0040-3+P901ACS800-01-0050-3+P901HD22010-3VI8345-2022421001IC693ALG223IC695CPU310IC695LRE0011771-IXEIC693MDL6556ES5318-8MB126ES5318-8MB13140ARI03010PCS100FZ253B-1-40-131C110-503-4-00610859-B211756-ENBT1756-IB321756-L621756-OB32A20B-8200-05455136-RE2-PCI1756-IB16ISOE1756-IF161756-IR6I/A1756-L611756-OB16I1771-IXE/DIC697BEM733IC697CGR935IC697BEM733IC697CGR9358MSA7LR0-D9140CRA93200140CRP93200140NOE77101CACR-UP50AABTSXAEY1600TSXASY410TSXDEY16D2TSXP572634MTSXPSY2600MTSXMRPC003MPU515AA0810V20.2毫安D081024V0.5AACS510-01-07A2-43KWACS510-01-180A-490KWACS550-01-125A-455KWJAMSC-C811045C220B1010-01088PICA413171IRB4400/60RVS-DN310A06B-6087-H137TSX08CD12R8ASIPM02P0904HASA-G01-C5-C1-11SA-G01-C6-C1-111394C-AM031394C-AM041394C-AM07RM5G-4005IC697CGR935PCR-1820***12A-MAD02***2A-40CDR-ACQM1H-MAB42E5CZ-Q2NT1746-OB161756-ENBT1756-L611756-OB3220BC140A0AYNANC0A06B-6130-H002TSXDMZ28DRAO3805ETU1471DV-1000140ACI03000140ACO02000140CPU67160140DAI75300140DAO85300140NOE77101602453-59A6ES7400-0HR00-4ABOMVME55006E0163140ACI04000INICT03AATCS-151756-N2626B11***651CD2S2N653B-8-200-2CPU44.01.2H140CPU671606DS1412-8RR6DS1717-8RR6DS1723-8BB879DEX-G11770-CD1140CPS11420140CPU65160140CRP93200140XBP01000140XCP51000490NOR00003PTQ-PDPMV1HS840PL810FHA-40C-100-E250-CHA-655-4-200SGA200/150C-1AAAIC693CPU374IC693MDL660IC693PWR330MVME162-344C1FCM10EPCI-GPIBMFS068253B-1-40-16F***801-2BJ13-4AA06***6648-0AC11-3AX06***6648-0AE11-3AX0EXE602E246-842-026AR1302-0AD00-0AA01746-OB161756-A131756-ENBT1756-IB321756-IF81756-L611756-N21756-OB321756-OF41756-PA721756-TBCH1756-TBNH20BC140A0AYNANC01746-OB161756-A131756-ENBT1756-IB321756-IF81756-L611756-N21756-OB321756-OF41756-PA721756-TBCH1756-TBNH20BC140A0AYNANC0ZX345QDCM10EFBM042771B70011785-V40L140***I03000LBB4421/10LBB4422/10PC-GF202094-BC02-M02-M2094-BMP5-M2094-SE02F-M00-S1ACS510-01-07A2-4NIPCI6034EX-AM7000FBM201FBM23707KT9475RTA-PDEFB3HNE00313-1M25R驱动器1747-L20ETC-IAH161TC-IDD32163-122-0155105253246EV3054-0CC140CPU67160D3-05B-1RDCO-02CSGMRS-13A2A-YR116ES7414-3EMO5-0ABORL-1600RL-3200RLE-8002281PB-IF-03/HWV1.02FPU120S-A106ES5246-4UB21A02B-0094-C0416ES5460-4UA13XFR20-130FCW504-02-X101-CA06B-6087-H115A06B-6088-H222#H5001756-ENBTIC670ALG320IC697ALG230IC697MDL653IC697MDL7501771-A3B1771-CP21771-P76AR1301-0DD10-0AA06AR1302-0AD00-0AA01756-CNB1756-OB16E1756-PA726FC5203-0AF00-0AA16FC5210-0DF31-2AB0IC670MDL2416F***801-2BJ13-4AA0ALU21501336F-B020-AA-EN05701-A-0301CG6500CCPS-12NNT8-70032MD-420.00-000DCS800-S01-1500-04DFU1514W1179BX12CR14VS364140CRP93100MA-0185-100MA-0186-1001746-A131746-IV161746-NIO4V8290-1471746-NIO4VSS503H-3-D3VCP25.2DVN-003-NN-NN-PW140CPU11303416NHM300302301AQPI30200S2P-B1756－CNBR/E1756-IB321756－IB32/A1756-IF161756－L611756－L621756－OB16E/A1756-PA751757-SRM1771-CP2RM78406ES7134-4JB00-0AB06GK7243-1EX01-0XE0M-430HGPFTL101A-1.0KN138LP-4-CRDC2UL124VUL2/3MAX75VCV3-P65GV2-PM07C1.6~2.5AGV2-PM08C380VAC2.5AGV2-PM16C10A-14A1771-CP23700A4329MP30081747-PIC140CPU67160490NRP95400140CPU11302MDD065D-N-060-N2M-095PB1G1531-60010HW9380962-AIC697ALG320A20B-2902-0411IMDS014197A3HAC023447-0013HAC5689-13HAC7998-1INNIS21INNPM22JTD321)
