Fault Diagnosis and Prevention of Low Voltage Reactor in EHV Substation

Tsawg voltage reactors yog ib qho ntawm cov khoom siv hluav taws xob tseem ceeb hauv ultra high voltage substations, thiab feem ntau tuaj yeem muab faib ua series reactors thiab parallel reactors. Tsawg-voltage reactors thiab cov tsev txhab nyiaj capacitor tsim cov kab hluav taws xob sib txuas, uas tuaj yeem cuam tshuam kev hloov pauv ntawm cov dej ntws thiab txwv kev sib raug zoo dua, tiv thaiv lub capacitor, thiab tiv thaiv kev puas tsuaj rau lub capacitor; Shunt reactors feem ntau tuaj yeem siv los them cov nqi hluav taws xob reactive, tswj thiab stabilize daim phiaj hluav taws xob, thiab txhim kho qhov hluav taws xob waveform kom ntseeg tau tias kev lag luam txhim khu kev qha, txo qhov kev poob, thiab txhim kho daim phiaj hluav taws xob zoo. Nrog rau kev nce hauv hluav taws xob txuas ntxiv, kev nthuav dav sai ntawm ultra high voltage fais fab daim phiaj, thiab kev txhim kho ntawm kev tswj tsis siv neeg xws li AVC, tus naj npawb ntawm cov hluav taws xob qis reactors tau nce sharply. Tsis tshua muaj hluav taws xob qhuav hom reactors tau siv dav hauv cov tshuab hluav taws xob vim lawv qhov kev ua tau zoo, tus nqi qis, thiab kev yooj yim ntawm kev ua haujlwm thiab kev saib xyuas. Txawm li cas los xij, ntau cov ntaub ntawv thiab cov teeb meem tsis tshua muaj hluav taws xob tsis muaj hluav taws xob tsis zoo qhia tau tias tsis muaj hluav taws xob qhuav reactor tsis ua haujlwm feem ntau tshwm sim los ntawm cov khoom xws li kev hloov pauv ntau dhau, hloov cov khoom qub, kev puas tsuaj ntawm rwb thaiv tsev kev ua tau zoo, thiab kev puas tsuaj ntawm rwb thaiv tsev, cuam tshuam loj heev. txhim khu kev qha kev khiav hauj lwm ntawm lub hwj chim system. Tshwj xeeb tshaj yog nyob rau hauv xyoo tas los no, ob peb hom qhuav cua core reactor hluav taws kub sib tsoo tau tshwm sim hauv Shandong Hluav Taws Xob UHV fais fab hluav taws xob ib leeg, ua rau muaj kev lag luam loj. Raws li kev sab laj cov ntaub ntawv muaj feem xyuam thiab tso siab rau kev ua haujlwm thiab kev saib xyuas ntawm cov khoom siv hluav taws xob tsawg hauv Shandong Hluav Taws Xob UHV Grid, daim ntawv no tau txheeb xyuas qhov ua rau thiab cov yam ntxwv ntawm qhov tsis muaj hluav taws xob qis reactor, sau cov txheej txheem rau kev kuaj xyuas qhov tsis muaj hluav taws xob qis reactor. , thiab tawm tswv yim kev tiv thaiv zoo rau kev ua txhaum ntawm cov hluav taws xob qis qis hauv UHV substations. Kev tshawb fawb tseem ceeb ntawm daim ntawv no yog raws li hauv qab no: (1) Kev ua txhaum ntau hom thiab ua rau cov hluav taws xob qis hauv cov hluav taws xob hluav taws xob hluav taws xob raug tshuaj xyuas. Ua ntej, cov kev ua txhaum feem ntau ntawm cov khoom siv hluav taws xob qis qis hauv EHV substations tau teev tseg, thiab cov teeb meem tsis muaj hluav taws xob qis reactor tau tshwm sim hauv cov phiaj xwm hluav taws xob hauv xyoo tas los no tau hais los qhia lawv; Tom qab ntawd, ua ke nrog cov ntaub ntawv kawm, cov laj thawj ntawm kev ua tsis tiav ntawm cov hluav taws xob qis qis hauv EHV substations tau sau tseg thiab ua kom zoo dua. (2) Ib txoj kev kuaj mob dav dav rau qhov tsis muaj hluav taws xob qis hluav taws xob hauv cov hluav taws xob hluav taws xob ultra high voltage tau kawm. Firstly, aiming ntawm tej yam txhaum cai thiab ua rau cov low-voltage reactors nyob rau hauv ultra-high voltage substations, daim ntawv no teev cov feem ntau txhaum txoj kev kuaj mob rau tsawg-voltage reactors, thiab soj ntsuam nyob rau hauv kom meej cov ntsiab lus, lub luag haujlwm, thiab qhov zoo thiab qhov tsis zoo ntawm ntau yam. diagnostic txoj kev nyob rau hauv kev siv tswv yim. Tsis tas li ntawd, cov txheej txheem ntawm kev kuaj mob zoo rau kev ua haujlwm ntawm daim phiaj hluav taws xob thiab kev saib xyuas yog tsim; Tom qab ntawd, siv lub tshuab hluav taws xob ultra high voltage ntawm Shandong Power Grid ua piv txwv, daim ntawv thov ntawm cov txheej txheem kev kuaj mob no tau txheeb xyuas. (3) Kev tiv thaiv zoo rau kev ua txhaum ntawm cov khoom siv hluav taws xob tsawg hauv cov hluav taws xob hluav taws xob ultra-high voltage substations tau npaj tseg, txhawm rau tshem tawm cov teeb meem kev nyab xeeb thaum ntxov thiab tiv thaiv kom tsis txhob muaj xwm txheej tshwm sim. Ua ntej, txheeb xyuas cov hauv paus ntsiab lus ntawm ntau yam kev tiv thaiv kev tiv thaiv, suav nrog kev txhawb nqa cov cuab yeej nkag mus rau kev tswj hwm, ntxiv dag zog rau kev ua haujlwm thiab kev saib xyuas, txo qis kev hloov pauv tam sim no, thiab hloov cov overvoltage, thiab piav qhia txog qhov kev siv ntawm txhua qhov kev ntsuas. Tom qab ntawd, tsom mus rau kev tshawb fawb ntxiv rau qhov tob ntawm cov thev naus laus zis tshiab xws li kev xaiv theem thiab kaw cov hluav taws xob tsis tshua muaj hluav taws xob, txhawm rau txo qis overvoltage thiab kaw inrush tam sim no thaum kaw kev ua haujlwm ntawm cov hluav taws xob tsis tshua muaj hluav taws xob hluav taws xob los ntawm kev siv cov thev naus laus zis xws li theem xaiv thiab kaw, thiab hais txog lub hauv paus ua rau cuam tshuam kev cuam tshuam ntawm cov hluav taws xob tsis tshua muaj hluav taws xob reactors.

Cov ntsiab lus saum toj no yog tsim los ntawm Superb heater Company, super heater. Kev tsim khoom tseem ceeb: cov khoom siv cua sov, ntsuas kub, cov khoom siv, cov khoom siv, thiab cov khoom siv raw xws li tubular rhaub, tubular rhaub, siv cua sov, ceramic rhaub, silicone roj hmab rhaub, thermocouples, thiab lwm yam.
