Zogulitsa ndi kuchuluka kwa ntchito

● Mtima: Mtima umapangidwa ndi zinthu zingapo zofanana, ndipo capacitor element imakulungidwa ndi capacitor paper (yapakati) ndi aluminiyamu conductor (mbale).Ma element pole pole onse akutulukira kunja kwa sing'angayo, ndipo mbale imodzi ya pole imawotchedwa ndi chitoliro cha madzi ozizira, ndipo imalumikizidwa ndi choyikapo pansi kapena mbale yapansi pa chivundikiro kudzera pa chitoliro cha madzi ozizira, chomwe ndi potulutsira madzi onse. mbale yamtengo.
●Chingwe chachiwiri chimatsekedwa ndi chipolopolo, cholumikizidwa ndi ndodo yolondolera ndi chingwe cholumikizira, ndikukokedwa ndi manja a porcelain pachikuto.
● Chipolopolo: Chipolopolo cha bokosi ndi rectangle, ndipo pali zopachika zowotcherera mbali zonse za khoma la bokosi kuti azinyamulira.Chophimbacho chimakhala ndi manja a porcelain omwe ali ndi nyanga ndi nsonga yapansi kapena thumba loyambira.
1. Zimapangidwa ndi filimu ya polypropylene yokhala ndi makhalidwe abwino afupipafupi monga sing'anga, zojambulazo za aluminiyamu monga electrode, mawonekedwe a filimu yonse, ndi mafunde osagwiritsa ntchito inductive.
2. Chipolopolo chachikulu cha aluminiyamu, njira imodzi yotulukira kunja, yokhala ndi madzi ozizira.
3. Imakhala ndi mphamvu yopitilira muyeso, kugwiritsa ntchito pafupipafupi komanso kutayika kochepa.
4. Ndikoyenera kuwongolera ma resonant frequency and super audio frequency induction induction zida zotenthetsera kuwongolera mphamvu yamagetsi kapena kusintha mawonekedwe adera.

Kuyitanitsa zambiri ndi Kukhazikitsa

Kusankhidwa kwa voliyumu yovotera ya capacitor kuyenera kutengera mphamvu yamagetsi.Poganizira kuti athandizira capacitor kuonjezera voteji, kotero posankha oveteredwa voteji wa capacitor, ndi osachepera 5% apamwamba kuposa voteji maukonde ;pakakhala riyakitala mu capacitor circuit, voteji ya terminal ya capacitor Pansi imawonjezeka ndi kuchuluka kwa riyakitala pamndandanda, kotero posankha voteji yovotera ya capacitor, iyenera kutsimikiziridwa pambuyo powerengera molingana ndi kuchuluka kwa reactance. wa riyakitala mu chingwe.Ma capacitor ndi njira zochepetsera za ma harmonics.Pansi pa ma harmonics, kuchuluka kwa ma harmonics kudzalowetsedwa mu ma capacitors kuti ma capacitors apitirire kapena kupitirira.Kuonjezera apo, ma capacitors adzakulitsa ma harmonics ndikuyambitsa resonance ikatha, kuyika pachiwopsezo chitetezo cha gridi yamagetsi ndikupanga moyo wa ma capacitors.Chifukwa chake, ma capacitor okhala ndi ma harmonics akulu ayenera kugwiritsidwa ntchito pansi pa ma reactor omwe amapondereza ma harmonics.Kuthamanga kwamakono pamene capacitor yatsekedwa ikhoza kukhala yokwera ngati mazana a nthawi zowerengetsera zamakono za capacitor.Chifukwa chake, chosinthira chosinthira capacitor chiyenera kusankha chosinthira popanda kusokonezanso.Pofuna kupondereza kutseka kwa inrush panopa, riyakitala yomwe imapondereza inrush panopa ingathenso kulumikizidwa mndandanda.Pamene capacitor yokhala ndi kukana kutulutsa mkati ikachotsedwa pamagetsi, imatha kutsika kuchokera pamtengo wapamwamba wamagetsi ovotera mpaka pansi pa 75V mkati mwa mphindi 10.kufotokozedwa liti.Ma capacitor omwe amagwiritsidwa ntchito polipira mzere ayenera kukhazikitsidwa pa 150 ~ 200kvar pamalo amodzi, ndipo samalani kuti musakhazikitse ma capacitor pa siteji yomweyi ndi thiransifoma, ndipo musagwiritse ntchito gulu lomwelo la osiya kuti mupewe kuwombera kwambiri chifukwa cha ferromagnetic resonance pamene mzere sukuyenda mu magawo onse.Kuchuluka kwamagetsi komweku kumatha kuwononga ma capacitor ndi ma transfoma.The zinc oxide surge arrester pofuna kuteteza kuwonjezereka kwa ntchito ziyenera kusankhidwa kwa zinc oxide Surge arrester yoperekedwa kwa capacitor, ndipo ndi bwino kuyiyika pakati pa mitengo ya capacitor.Fuse yomwe imagwiritsidwa ntchito makamaka pa capacitor imasankhidwa kuti ipumuke mwachangu, ndipo yomwe idavoteledwa iyenera kusankhidwa molingana ndi nthawi 1.42 ~ 1.5 yamagetsi ovotera a capacitor.Pamene capacitor imalumikizidwa mwachindunji ndi injini yothamanga kwambiri mofananira, kuti mupewe kudzidzidzimutsa pamene galimoto imachotsedwa pamagetsi, zomwe zimapangitsa kuti voteji ya capacitor terminal ikweze kuposa mtengo wovotera, wovotera panopa. capacitor ayenera kukhala osachepera 90% ya palibe katundu panopa galimoto;Mukamagwiritsa ntchito waya wa Y / △, sikuloledwa kulumikiza capacitor molunjika ku injini mofanana, ndipo njira yapadera yolumikizira iyenera kutsatiridwa.Capacitor ikagwiritsidwa ntchito pamalo okwera kuposa 1000 metres kapena capacitor ikugwiritsidwa ntchito m'malo otentha otentha, ziyenera kunenedwa poyitanitsa.Zitsimikizo zapadera za spe kapena zofunikira zapadera za capacitors ziyenera kufotokozedwa poyitanitsa.

Kukhazikitsa ndi kugwiritsa ntchito:
● Kuyika kwa ma capacitor sikuloledwa kukhala ndi zochitika za vibration.Zimaloledwa kuyika ma capacitor pafupi ndi chowotchera, koma zinthu zosayaka ziyenera kugwiritsidwa ntchito ngati makoma ogawa kuti azizungulira ma capacitors kapena kuziyika mu kabati yosiyana yachitsulo.
● Kuti muteteze chitoliro cha madzi ozizira capacitor kuti chisawonongeke, kutentha kwa malo opangira capacitor sikuyenera kutsika kuposa ± 2 ℃.
● Capacitor iyenera kuikidwa molunjika (chovala cha porcelain chikuyang'ana mmwamba).Ndikoletsedwa kugwiritsa ntchito manja a porcelain kusuntha capacitor, ndipo pakati pa ma capacitors ndi osachepera 20 mm.
● Kugwirizana pakati pa mipope ya madzi ozizira a capacitor ndi kugwirizana pakati pa chitoliro cha madzi ozizira ndi chitoliro cha madzi chiyenera kupangidwa ndi mipope yofewa ya rabara.Mapaipi amadzi ozizira amatha kulumikizidwa mndandanda, koma osapitilira ma capacitor atatu.Chitoliro chokhetsa sichiyenera kutsekedwa, ndipo chiyenera kuikidwa pamalo omwe zimakhala zosavuta kuyang'ana kutuluka kwa madzi, kuti madzi atuluke aziyang'aniridwa nthawi iliyonse.
● Kutentha kwa madzi ozizira sikuyenera kupitirira +30 ℃ polowera ndi +35 ℃ potulukira.
Pamene mipope yambiri yamadzi ozizira imalumikizidwa mndandanda (mpaka 3 seti), kuthamanga kwa madzi ndi kumwa madzi kungasinthidwe kuti musinthe kusiyana kwa kutentha pakati pa madzi olowera ndi kutuluka, kuti kutentha kwa malowo kusapitirire. + 35 ℃, ndipo kuthamanga kwa madzi ozizira polowera sikuyenera kupitirira 4 mpweya wa mumlengalenga.
● Ngati madzi atayimitsidwa chifukwa cha vuto, mphamvu ya capacitor iyenera kudulidwa nthawi yomweyo.Pamene capacitor yatha ntchito chifukwa cha vuto, madzi onse mupaipi yamadzi ozizira ayenera kutsanulidwa.
●Pamene mawotchi angapo amagulu pa capacitor agwiritsidwa ntchito mofanana, pepala lolumikizana losinthika liyenera kugwiritsidwa ntchito.Panthawi imodzimodziyo, chotulukapo chachikulu chiyenera kutulutsidwa kuchokera ku mgwirizano wosinthika, ndipo sichiyenera kuchotsedwa ku malo aliwonse omwe ali m'magulu.Malo ophatikizika a chidutswa cholumikizira sichiyenera kukhala chochepera 2.5cm2.
● Pamene magetsi a mzere ndi apamwamba kuposa magetsi ovotera a capacitor, chiwerengero cha ma capacitor omwe amagwirizanitsidwa mndandanda akhoza kusinthidwa kapena chitsogozo chilichonse mu capacitor cholumikizidwa mndandanda chingagwiritsidwe ntchito mndandanda.
