Mafotokozedwe Akatundu

Capacitor yoteteza imalumikizidwa molumikizana ndi chosinthira cha vacuum.Pamene vacuum lophimba chikugwirizana ndi inductive katundu, izo sizingakhoze kokha kuchepetsa ntchito overvoltage kwa osiyanasiyana osiyanasiyana, komanso kuchedwetsa kuwuka nthawi ya odulidwa-odulidwa overvoltage ndi kukonzanso poyatsira overvoltage yoweyula mutu ndi kuchepetsa steepness, potero. Kuteteza Zida zamagetsi zimatetezedwa ku mphepo yamkuntho yakutsogolo.
Amagwiritsidwa ntchito mumagetsi a 50Hz, 3kV, 6kV, 10kV, 35kV kuti apange chomangira champhamvu chokhala ndi resistor.Zimagwiritsa ntchito mphamvu zomwe zimatengedwa ndi capacitor kuti zichepetse matalikidwe amagetsi komanso mphamvu yochepetsera ya resistor kuti ichepetse kutsika komanso kupewa kuchulukirachulukira.Njira yokhazikitsira malo osalowerera ndale ndi yochepa kuti iwonetsetse kuti ikugwirizana ndi mulingo wotsekera wa mota ndikuwongolera mphamvu yamagetsi ya gridi yamagetsi.
Nthawi zina, itha kugwiritsidwanso ntchito ngati capacitor yamphamvu kwambiri.Ikalumikizidwa pakati pa mizere ndi pansi, imatha kuchepetsa kuchulukitsitsa kwa mumlengalenga, kutsetsereka kwa mafunde ndi nsonga-mpaka.
Itha kuteteza zida zamagetsi zikagwiritsidwa ntchito ndi zomangira;ndi capacitor yofananira ya RC overvoltage mayamwidwe kachipangizo ka vacuum circuit breaker system.

Magawo aukadaulo ndi kukula kwake

■Kuchita mwaukadaulo
● Kupatuka kwa mphamvu: -5%~+10%.
●Kutayika kwa dielectric tangent value tanδ
Pansi pa voliyumu yovotera Un, pa 20 ℃:
A. Kwa makanema apakanema amapepala: tanδ≤0.002.
B. Kwa sing'anga yonse ya kanema: tanδ≤0.0005.
● Mafupipafupi: fn=50Hz.
● The capacitor akhoza kuthamanga kwa nthawi yaitali pansi pa 1.1Un, ndipo akhoza kupirira overvoltage opareshoni chifukwa cha kutsegula ndi kutseka kwa dera breaker ndi nsonga woyamba mtengo ≤2.5 2Un.
● Capacitor imatha kuthamanga kwa nthawi yayitali pansi pa 1.5In, pakali pano ikuphatikizapo zomwe zikuchitika chifukwa cha kuwonjezereka kwamphamvu, kumaphatikizapo zomwe zimayambitsidwa ndi ma harmonics, komanso zimaphatikizansopo zomwe zikuwonjezeka chifukwa cha kupatuka kwa capacitance.
● Njira yozizirira: kutengera kwachilengedwe kwa mpweya pamwamba pa chipolopolo cha capacitor.
● Kutalika kwa malo oyika ndi ntchito sikuyenera kupitirira 1000m;yozungulira mpweya kutentha osiyanasiyana unsembe ndi ntchito m'dera: m'nyumba -40+45 ℃;mpweya wachibale chinyezi ≤95%.
● Malo oikapo ndi opangira ntchito asakhale opanda mpweya wowononga ndi nthunzi;palibe fumbi la conductive kapena kuphulika komanso kugwedezeka kwakukulu kwamakina.
● Pasakhale fumbi ndi dothi lambiri pamwamba pa manja a ceramic a capacitor.Ngati mafuta akutuluka, ntchitoyo iyenera kuyimitsidwa.

Zogulitsa ndi kuchuluka kwa ntchito

Capacitor imapangidwa makamaka ndi chipolopolo ndi pachimake.Chigobacho chimawotchedwa ndi mbale yopyapyala yachitsulo, chivundikirocho chimakhala ndi manja adothi, ndipo mbali zonse zakhoma zimalumikizidwa ndi mbale za Angle kuti zikhazikike.Pachimake amasonkhanitsidwa lonse ndi chigawo chimodzi, ndi insulating mbali ndi hoop zolimba, ndi sing'anga sing'anga ndi wophimbidwa ndi electrode olekanitsidwa ndi izo.
Zida zotetezera zapamwamba komanso zogwira ntchito kwambiri zimasankhidwa ngati zofalitsa zolimba, ndipo njira yapadera yotulutsa mpweya wa vacuum imagwiritsidwa ntchito kuti isungunuke zitsulo kuti zipange galimoto inayake.Zimapangidwa kukhala gawo la capacitor pamakina odzigudubuza okha, kenako amapangidwa kukhala capacitor yokhala ndi ukadaulo wovomerezeka, kenako amagwiritsidwa ntchito motsatizana ndi chopinga chapadera chopanda inductive.

Nthawi zogwirira ntchito:

1. Kutentha kwa mpweya wozungulira: -40°+45℃, chinyezi wachibale osapitirira 95%.
2. Palibe mpweya wowononga ndi nthunzi pamalo oyikapo, palibe fumbi loyendetsa kapena lophulika komanso kugwedezeka kwakukulu kwamakina.
3. Njira yoyika: unsembe wowongoka.

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.
