Tib Shunt Capacitor Tiv Thaiv Fuse

1" Pawg tawg" qhov tshwm sim Nws tau paub zoo tias qhov hluav taws xob high-voltage fuses yog qhov kev tiv thaiv tseem ceeb rau kev ua haujlwm ntawm sab hauv ntawm ib lub capacitor hauv ib lub peev xwm loj sib luag. Thaum tag nrho pawg ntawm capacitors fused lossis ib theem raug fused, qhov fusing yog ib qho tom qab ib ntu rau ib lub sijhawm. Qhov tshwm sim no hu ua" pab pawg tawg" ;. Piv txwv," pawg tawg" qhov tshwm sim tau tshwm sim hauv peb lub chaw lis haujlwm, uas ua rau 9 tus neeg tswj hwm tsis ua haujlwm." pawg tawg" tshwm sim feem ntau muaj cov yam ntxwv nram qab no: (1) Tom qab" pab pawg tawg" ntawm lub txhab nyiaj tso tawm sab nraud, cov tshuaj ntsuam xyuas pom tuaj yeem pom tau tias cov nplaim fuse tiv thaiv raj tawm thiab hlawv, thiab lub raj tiv thaiv txuas nrog txuas tus Tsov tus tw hlau. (2)" Pawg tawg" tuaj yeem tshwm sim nrog lossis tsis muaj cov tshuaj reactors. (3) Tsis muaj teeb meem dab tsi zoo ntawm cov xov hlau," pawg tawg" yuav tshwm sim. Txheeb cais qhia tau tias qhov tshwm sim ntawm cov hlau txuas hluav taws xob muaj ntau dua. (4)" Pawg tawg" feem ntau tshwm sim hauv huab cua phem lossis thaum kawg ntawm kev ua haujlwm. (5) Kho lub peev xwm tsis muaj peev xwm tiv thaiv" pawg tawg" ;. (6) Thaum" pawg tawg" tshwm sim, kev tiv thaiv yuav tsis khiav lag luam feem ntau, yog li ntawd lub Circuit Court breaker yuav tsis muaj kev tawm mus. 2" pawg tawg" vim li cas (1) Tom qab lub fuse raug tshuab, tus Tsov tus tw hlau tsis tuaj yeem sib cais los ntawm lub raj tiv thaiv. Cov fuses uas tam sim no siv yog feem ntau cov tshuaj tsuag-los-txau, thiab tus Tsov tus tw hlau yuav tsum tuaj yeem ntseeg tau cais tawm ntawm lub raj tiv thaiv tom qab nws tshuab. Txwv tsis pub, qhov ntsuas hluav taws xob ntawm lub raj tiv thaiv yuav yog: theThaum lub fuse raug tshuab thaum lub sijhawm ua haujlwm, qhov voltage ntawm lub raj tiv thaiv yog lub zog hluav taws xob rov qab voltage ntawm ob qho kawg ntawm qhov tawg. Rau lub txhab nyiaj capacitor nrog lub hnub qub txuas, qhov hluav taws xob no yog 2 npaug ntawm cov hluav taws xob theem siab tshaj plaws. Tus nqi; rau delta-kev txuas nrog capacitor nyiaj hauv tuam txhab, qhov hluav taws xob no yog 23 npaug ntawm cov theem hluav taws xob ntau. Thaum qhov seem hluav taws xob nyob rau ntawm feem ntawm feem uas tsis tawg los ntawm qhov txhaum capacitor ploj, qhov voltage uas tiv thaiv lub raj ntawm lub hnub qub puab thiab txuas-txuas nrog capacitor txhab tiv thaiv raj tiv thaiv kab yog qhov ntau theem voltage thiab qhov siab tshaj plaws 3 -phase voltage thaum ua haujlwm. Thaum lub txhab tso nyiaj rau ntawm tus neeg siv lub peev xwm raug tso rau kev ua haujlwm, yog tias qhov fuse ntawm tus capacitor tau raug tshuab thiab nws tsis raug tshawb pom, tus Tsov tus tw hlau tsis cais. Feem ntau, qhov seem hluav taws xob ntawm lub faulty capacitor tau ploj, yog li lub hnub qub thiab qeeb qeeb Lub chaw txuas hluav taws xob tiv thaiv kab hluav taws xob tiv thaiv lub raj yuav tseem tiv taus 2 zaug ntawm qhov hluav taws xob theem kawg thiab 23 zaus qhov hluav taws xob theem voltage feem. Nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob saum toj no, yog tias cov fuse uas tau ntsia sab nraum zoov ntsib cov huab cua phem, nws tuaj yeem tawm ntawm cov nplaim hluav taws tiv thaiv thiab ua rau nws hlawv. Nyob rau tib lub sijhawm, lwm tus neeg txuas hluav taws xob txuas nrog ua ke nrog nws yuav tsim cov hluav taws xob tso tawm tam sim no mus rau lub faulty capacitor, ua rau muaj kev tiv thaiv loj thiab fusing los tsim" pawg tawg" ;. Nyob rau hauv delta-txuas capacitor bank, tus overcurrent tsuas yog cuam tshuam hauv qab thiab tej zaum yuav ua rau tag nrho cov txhab nyiaj ntawm cov neeg siv hluav taws xob txuas. (2) Qhov ntsuas tam sim no ntawm lub fuse yog qhov tsawg heev. Thaum xaiv tus ntsuas tam sim no ntawm lub fuse, koj yuav tsum xav txog qhov sib piv nrog qhov ntsuas tam sim no ntawm lub capacitor. Cov peev txheej raug tso cai ua haujlwm ntev ntev nyob rau hauv 1.3IN, thiab tso cai rau kam rau ua ntawm cov nqi capacitance yuav tsum -5 % ～ |10 %. Yog li ntawd, hauv kev ua haujlwm, kev khiav hauj lwm tam sim no ntawm qee lub capacitors tuaj yeem ncav qhov ntsuas tam sim no ntawm 11 × 13 = 143. Yog li no, IEC549 tau sau tseg tias qhov piv ntawm qhov ntsuas ntawm lub ntsuas hluav taws xob mus rau lub ntsuas tam sim no ntawm lub capacitor yuav tsum ntau dua 143 zaug. Tus qauv ntawm GB3983-85" Shunt Capacitor" qhov sau tseg tias nws yog 1.5 txog 1.6 npaug, thiab tus thawj ntawm Tuam Txhab Saib Xyuas Cov Dej thiab Cov Hluav Taws Xob Hluav Taws Xob SDJ25-85 tau sau tseg tias nws yog 1.5 txog 2.0 npaug. Txawm li cas los xij, hauv lub txhab tso nyiaj capacitor nrog" pawg tawg" qhov tshwm sim, qee qhov sib piv tsuas yog 1.35 txog 1.37, thiab qee qhov txawm tias me dua. Raws li kev txheeb cais, qhov tsis sib xws ntawm cov qib tam sim no ntawm cov fuses hauv tsev feem ntau yog ntau dua 20 %. Xav txog cov txiaj ntsig no, cov kev xav kom pom zoo tam sim no yog 1.7 txog 1.8. (3) Qhov kev ua tiav ntawm kev fuse yog qhov tsis zoo. Lub fuse yuav tsum tsis txhob reignite thaum nws tawg lub teev tshwj xeeb tam sim no, txwv tsis pub nws yog sib npaug ntawm ib pawg ntawm ntau cov hluav taws xob uas siv hluav taws xob txuas tau txiav tawm thiab tom qab ntawd rov nkag, uas yuav ua rau cov capacitors ua hauj lwm nyob rau hauv thaum uas tig mus rau nws. Qhov tawm tam sim no zoo tshaj qhov anti-inrush tam sim no muaj peev xwm ntawm cov fuse, uas ua rau nws fuse thiab ua rau" pawg tawg" ;. (4) Harmonic ua" pab pawg tawg" ;. Raws li kev hloov chaw tau nruab nrog cov khoom siv txuas ntxiv thiab cov cuab yeej hluav taws xob tsis xws li thyristor thiab hluav taws xob arc rauv, cov kev sib raug zoo txuas ntxiv. Thaum cov raug mob siab tam sim no nkag hauv lub capacitor, qhov tam sim no hauv lub voj nce siab, ua rau lub zog ntawm tus tshaj. Thaum lub sijhawm qeeb dhau lub sijhawm ncua sijhawm, ntau ntawm cov fusing yuav tshwm sim, sib sau" pawg tawg" qhov tshwm sim. 3 Kev Tiv Thaiv" pab pawg tawg" (1) Xaiv lub fuse nrog kev ua tau zoo dua. Thaum xaiv lub fuse, koj yuav tsum xaiv lub fuse tshwj xeeb uas muaj qhov ua tau zoo tawg thiab tsis muaj xee txheej. (2) Siv cov fuse tiv thaiv ib qho, thiab them sai sai rau nws qhov voltage theem yuav tsum tsim nyog. (3) Kho cov xaiv qhov sib piv ntawm qhov tam sim no ntawm cov fuse mus rau lub capacitor. Nws yuav tsum raug ua raws li SDJ25-85 txoj cai. (4) xaiv qhov tseeb inductance tus nqi ntawm cov series reactor. (5) Txais lub hnub qub txuas. Txhawm rau kom txo tsawg ntawm nplawm" pawg tawg" fuses, tus tswj hwm lub peev nyiaj yuav tsum sim siv cov xov hlau hluav taws xob.
