ABBEI803F3BDH000017R1***保护是变压器内部故障的主要保护元件，对变压器匝间和层间短路、铁芯故障、套管内部故障、绕组内部断线及绝缘劣化和油面下降等故障均能灵敏动作。当油浸式变压器的内部发生故障时，由于电弧将使绝缘材料分解并产生大量的气体，其强烈程度随故障的严重程度不同而不同。***保护就是利用反应气体状态的***继电器（又称气体继电器）来保护变压器内部故障的。在***保护继电器内，上部是一个密封的浮筒，下部是一块金属档板,两者都装有密封的***接点。浮筒和档板可以围绕各自的轴旋转。在正常运行时，继电器内充满油，浮筒浸在油内，处于上浮位置，***接点断开；档板则由于本身重量而下垂，其***接点也是断开的。当变压器内部发生轻微故障时，气体产生的速度较缓慢，气体上升至储油柜途中首先积存于***继电器的上部空间，使油面下降，浮筒随之下降而使***接点闭合，接通***信号，这就是所谓的“轻***”；当变压器内部发生严重故障时，则产生强烈的***气体，油箱内压力瞬时突增，产生很大的油流向油枕方向冲击，因油流冲击档板，档板克服弹簧的阻力，带动磁铁向干簧触点方向移动，使***触点闭合，接通跳闸回路，使断路器跳闸，这就是所谓的“重***”。重***动作，立即切断与变压器连接的所有电源，从而避免事故扩大，起到保护变压器的作用。***继电器有浮筒式、档板式、开口杯式等不同型号。如QJ-80型继电器，其信号回路接上开口杯，跳闸回路接下档板。所谓***保护信号动作，即指因各种原因造成继电器内上开口杯的信号回路接点闭合，光字牌灯亮。CP60P0961FRHE300GEN200D520422000MA-0185-100(B)14DBTAPMDS60A0015-5A3-4-00140CPU53414BSC752A001-011B30035H011C31116G041C31129G031C31132G011C31166G011C31169G021C31189G011C31192G011C31194G011C31197G011C31219G011C31222G011C31223G011C31227G011C31233G041C31234G011X00024H011X00093G423A99132G023A99158G015X00070G015X00070G045X00105G145X00119G015X00121G01ACU4222AMSFF5A/250VFPM-3120TVSGSP20-351B30035H011C31116G041C31129G031C31132G011C31166G011C31189G011C31194G011C31197G011C31219G011C31227G011C31233G041C31234G011X00024H013A99132G023A99158G015X00070G045X00119G015X00121G011775T-PMPP-1700LX-4032T-001ACC73451A430D78MVI56-MCMMVI56-MCM1747-L543J***-6400FSEM1756-A131756-IB161756-IF161756-OB16E1756-PA751756-TBCH1756-TBNHAP1210SCSG-602RSGSP20-35EN61558-11PH2KVA46HD-20-10K1756-PA75/B140CHS11000140CPU53414A140CRA93100140NOE771016FC5403-OAA20-OAAOA5E00100846CDMR-WIITMH071P6***3525-1EA01-0AX06ES5441-4UA112214-30SLQTTGJR5253100R027207KT98-ETH-DPAC31CR161CC5602GEAKR-10D-751746-N04I140CPU43412ACIMR-VB4A0002BBAHA24PHI16IPC5000/5600/5000V/5600CATV31HU40N4A140ACI04000140CHS11000140CPS11100140CRA93200140CRP93200FC98-NX2094-BC04-M03S2094-BM01-S2711-K9A1IRB4400A121NBC-3015X450-24TDCS300-3.5ESYS68K/CPU32XBK***P-5C200VACPM510V163BSE008358R1CIO-SERB486RA2291-4DV62-06-45-21747-L5431769-BA1769-L32E51305348-10051403224-100TK-PRR021TLM-8NO.C306GN3SERIESB16ES5246-4UA31JDK6209-2039-1KOMS-A27ML5221-2BA14/11A06B-6132-H002ND312TVLT5002P22B-03AGOTP75T3BOTP75T3MJEPMC-CP210CS4000SYS68KCPU-40B/16SPM5D2A6D6KKIS-8-10KNKIS-8-10KNFBM201YT204001-FSKOMS-A2CXP544AIMDER01PM510V163BSE008358R1TI545-11041747-L532EGT1675M-STBDPFXGP4501TADPFXGP4503TAD20V416030V41605V4160S-D4007-FS-D4008-FUAZ3455/3475WR-D4004MVI46-MNET1756-BA11756-IB161756-IF81756-OB16E1756-OF81756-A71756-IB321756-IF81756-L621756-OB321756-PA75MVI56-MCMHX3006ES7415-2XK04-0AB06ES7416-3XL00-0AB06ES7952-1KP00-0AA0IC693CPU36442FE35AF1061747-L531140CRA93200ZX345Q6ES5095-8FB010-60031-5275806-EU140CRA93200IFRATC-600AWAGO750-333HX-150LEWISMMC-A4PLUSM.1302.7096R1MDV60A0055-5A3-4-00140CPU67160MT-35替代MT-30140CHS11000140CPU53414A140CRA93100140NOE77101TYP14.630.33.0161785-BCMVT3-V86ES7315-2AH14-0AB06ES7321-1BH02-0AA06ES7322-1BH01-0AA06ES7331-7PF01-0AB06FC5403-0AA20-0AA06SN1118-0DG21-0AA01336F-MCB-SP1K6ES7315-2AG10-0AB01756-ENBT1C31129G03/1C31132G016***6671-5CL00-0AX0FELQ-51746-A101746-IV161746-OW161746-P21746-P41747-L551SE-600-241771-A1B1771-IVN1771-P6S1771-P71785-BCMA06B-6102-H211#520A06B-6130-H002A20B-2900-0310A20B-2901-0660A20B-2902-0290A20B-2902-0411C***T-01BB1ANT3FU20-10T1-F***57***1157***13140CPU43412A2711-T5A16L12711-T6C16L1TK-PRS021BNL2310XQFB000配套编码器30073504E351036643704E3805E4119A8321R2600DDSUB-3113UG4512-1AR20AGDR-71CFS300R12KE3/AGDR-71CIC694ALG223IC694ALG392IC694CHS392IC694MDL230IC694MDL240IC694MDL645IC694MDL740IC694PWR330IC695ALG600IC695ALG608IC695CHS012IC695CMM002IC695CPU310IC695ETM001IC695LRE001IC695MDL916IC695NKT001IC695PBM300IC695PSA040XPS-BCXPSBC11101785-BCM6NH9720-3AA00MPL-B320P-SK24AADSQC6513HAC025784-001506/00/20/003504E36643805E4119A5X00119G015X00121G011746-A13CI830EI803F8AC110.60-18AC122.60-18V1022.00-1140CPU43412A140NOE77100140CPS114206EP1334-2AA01E32R83032900701746-A101746-IV161746-OW161746-P21746-P41747-L55143AP-FA45C/PB-BA8AC110.60-18AC122.60-18V1022.00-18V1045.00-18V1090.00-1R3681PS-M06D12S5-NJ1L(S)MAGNUMVS50FG30-H208G1B140CPS11420140CPU67160A06B-0127-B675#7000-1IH80IQDP40IQDP806***3607-1JC20-0AX1KXA-80-10-201746-NI16IMFC-N31747-AIC1761-CBL-AM001761-NET-AIC1764-28BXB1764-LSP1769-ECR1769-IF41769-IQ161769-OB16P1769-OF2FR-A024-0.2K1756-0BI6I1756-CNB/E1756-DHRI01756-DNB1756-ENBT/A1756-IF81756-IM16I1756-L611756-PA75CP-9200SH/CPU6ES7412-2XG04-0AB0EE-04052-0421791-24A8P0926GHP0926GJ6ES7951-0AG00-0AA0IC200ALG430IC200MDL7506SC6508-4AA021746-NI81746-P41756-CNB/E1756DH+/RIO1756-DNB1756-ENBT/A1756-IM16I1756L611756-OB16IMVI56-MCMFPS-F5140CPU43412AA06B-6058-H006E5071-66571E1428AH2310240032X5126ES7478-2AC00-0AC0140CPU67160140XBP00600140XBP01000140XBP01600140XTS00200140XTS00500490NOR00003TVD1.2-08-03DS1404038DS1404038-E5TYP:0608830109FC-PA780CIC697CPU7801756-M16SE/A49-4100-03C51C31129G03)
