Magawo aukadaulo ndi kapangidwe kake

The main technical parameters :
Mphamvu yamagetsi: 6.3kV, 6.6kV, 6.6√3kV, 10.5kV, 11kV, 11√3kV, 12kV, 12√3kV, 19kV, ndi zina zotero;
Oveteredwa mphamvu: 30 ~ 400kvar, milingo ena voteji ndi mphamvu akhoza mwapadera analamula.
Kulekerera kwamphamvu: -5% ~ + 10%;
Kutaya kwamtengo wapatali: filimu ya pepala lopangidwa ndi sing'anga tanδ≤0.08%, sing'anga ya kanema wathunthu tanδ≤0.05%;
Kulimbana ndi magetsi: Ma capacitor ayenera kupirira nthawi za AC 2.15 kapena DC 4.3 nthawi yamagetsi ovotera, ndipo sipadzakhala kusweka kapena flashover kwa 10s;
Mulingo wa insulation: 6kV level 30kV, 10kV level 42kV AC test inatenga 1min popanda kusweka kapena flashover.
Kuchita zodzitchinjiriza: capacitor yokhala ndi kukana kutulutsa mkati, voliyumu yotsalira imatsika kuchokera pamtengo wapamwamba wa 2Un mpaka pansi pa 75V mkati mwa 10min mutatha mphamvu;
Zolemba malire kololeka overvoltage: 1.1 nthawi voteji oveteredwa, osapitirira maola 8 pa maola 24, 1.15 nthawi voteji oveteredwa, zosapitirira mphindi 30 pa maola 24, 1.2 nthawi voteji oveteredwa, zosapitirira mphindi 5.1.3 kuchulukitsa ndalama
Osapitilira mphindi imodzi pamagetsi osasintha.
Kuchuluka kovomerezeka kwaposachedwa: Mlingo wovomerezeka sudutsa nthawi .3 kuposa nthawi yomwe idavotera kuti igwire ntchito, ndipo kupitilira kwapanthawi kochepa kumaganizira kuchulukira, kupatuka kwabwino kwa capacitor ndi kukopa kwa ma harmonics, zomwe siziyenera kupitilira nthawi za 1.43 zomwe zidavotera pano.
Kutsata miyezo: Zogulitsa zimagwirizana ndi International GB/T 11024.1-2009 ndi International IEC60871-1:2005.

Zogulitsa ndi kuchuluka kwa ntchito

Capacitor imapangidwa ndi chipolopolo cha bokosi ndi pachimake.Chigoba cha bokosicho chimapangidwa ndi mbale zopyapyala zachitsulo posindikiza ndi kuwotcherera.Chigoba cha bokosicho chimakutidwa ndi manja a porcelain.Mbali ziwiri za khoma la bokosi zimakokedwa ndi zopachika kuti zikhazikike, ndipo mbali imodzi ya ma hanger imakhala ndi mabawuti oyambira.Pachimake capacitor amapangidwa ndi laminating angapo zigawo zikuluzikulu ndi insulating mbali, ndipo zigawo zikuluzikulu amapangidwa ndi kugudubuza ndi flatten mapepala awiri a aluminiyamu zojambulazo sandwiched pepala gulu sing'anga kapena sing'anga wathunthu filimu ngati mbale polar.Zigawo zomwe zili pachimake zimagwirizanitsidwa ndi mndandanda wina ndi zofanana kuti zikwaniritse zofunikira za ma voltages osiyanasiyana ndi mphamvu.Ma capacitor okhala ndi ma fuse amkati, chigawo chilichonse chimakhala ndi fusesi mndandanda.Chigawocho chikasweka, chigawo chokhazikika chomwe chimagwirizanitsidwa pamodzi ndi icho chidzatulutsa, kotero kuti fuseyo idzawomberedwa mofulumira mu milliseconds, ndipo gawo lolakwika lidzawombedwa.kudulidwa, kulola capacitor kupitiriza kugwira ntchito.Ma capacitor a magawo atatu amalumikizidwa ndi nyenyezi.Sing'anga yamadzi mu capacitor imagwiritsidwa ntchito kuyika sing'anga yolimba ndikudzaza ma voids mkati mwa capacitor.Ili ndi mphamvu zabwino kwambiri zamagetsi ndi thupi ndipo imagwirizana bwino ndi zida zina mu capacitor.

Nthawi zogwirira ntchito:

Kutalika sikudutsa 1000m, kutentha kozungulira ndi -40/B, ndipo kutentha kwakukulu kwa Gulu B ndi +45 ℃.Malo oyika alibe kugwedezeka kwakukulu kwamakina, palibe mpweya woyipa ndi nthunzi, palibe fumbi loyendetsa kapena lophulika.Ma capacitors ayenera kutsimikiziridwa kuti akugwira ntchito pansi pa mpweya wabwino, ndipo saloledwa kugwira ntchito pansi pa malo otsekedwa komanso opanda mpweya.Ma waya a ma capacitor ayenera kukhala ma conductor osinthika, ndipo dera lonselo liyenera kulumikizana bwino.

Kuyitanitsa zambiri

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.
