Makasitomala ambiri omwe amagula ma capacitor amphamvu mumakampani tsopano amasankha ma capacitor owuma. Chifukwa cha vutoli sichingasiyanitsidwe ndi ubwino wa ma capacitor owuma okha. Poyerekeza ndi ma capacitor amafuta, ali ndi zabwino zambiri pankhani ya magwiridwe antchito azinthu, kuteteza chilengedwe komanso chitetezo. Ma capacitor owuma tsopano pang'onopang'ono akhala otchuka pamsika. Nchifukwa chiyani tikulimbikitsidwa kugwiritsa ntchito ma capacitor owuma? Bwerani ku nkhani ya sabata ino kuti mudziwe zambiri za izi.

Ma capacitor odzichiritsa okha amagawidwa m'mitundu iwiri: ma capacitor amafuta ndi ma capacitor ouma. Ma capacitor ouma, monga dzinalo likusonyezera, omwe amasankhidwa ndi mtundu wa insulation wosakhala wamadzimadzi. Ma filler a ma capacitor ouma omwe ali mumakampani masiku ano ndi mpweya wosagwira ntchito (monga sulfure hexafluoride, nayitrogeni), microcrystalline paraffin ndi epoxy resin. Ma capacitor ambiri oviikidwa mumafuta amagwiritsa ntchito mafuta a masamba ngati chothandizira kuviika. Ma capacitor ouma sagwiritsa ntchito mankhwala owononga chilengedwe monga ma impregnants ndi utoto popanga. Poganizira zinthu zopangira, njira yopangira, kugwiritsa ntchito mphamvu, magwiridwe antchito pa moyo ndi mayendedwe komanso kutaya komaliza, ma index onse owunikira momwe chilengedwe chimakhudzira ndi ma capacitor amafuta, omwe angatchedwe kuti ndi mankhwala abwino kwa chilengedwe.

Pali mitundu yosiyanasiyana ya ma capacitor amphamvu pamsika masiku ano, koma makampani ochepa kwambiri amagwiritsa ntchito ma capacitor amafuta. Pali zifukwa ziwiri zazikulu zomwe zapangitsa kuti ma capacitor amafuta asiye kugwiritsidwa ntchito.

1. Mbali za chitetezo

Pamene ma capacitor amafuta akugwira ntchito, mbali imodzi, kutuluka kwa mafuta ndi kutuluka kwa madzi kudzapangitsa kuti zigawo zamkati ziwonongeke; mbali inanso, chipolopolocho chidzapangitsa kuti mafuta atuluke ndi kutuluka kwa ma capacitor chifukwa cha dzimbiri.

1. Kukalamba kwa insulation kudzapangitsa kuti mphamvu ya ma capacitor itsike

Mafuta oteteza ku dzuwa a capacitor yamafuta adzawonjezera asidi pamene kuchuluka kwa ukalamba kukukwera, ndipo asidi amawonjezeka mofulumira pamene kutentha kukukwera; mafuta oteteza ku dzuwa a capacitor yamafuta amapanganso asidi ndi madzi mu ukalamba, ndipo madziwo amakhala ndi mphamvu yowononga pa filimu yachitsulo, zomwe zimapangitsa kuti mphamvu ya capacitor yamphamvu ichepe komanso kutayika kukuwonjezeka.Kaya ndi kuchepa kwa mphamvu ya capacitor kapena vuto la ngozi ya chitetezo, mavuto ambiri amayamba chifukwa cha mafuta oteteza. Ngati mpweya umagwiritsidwa ntchito ngati chodzazira, sichingoletsa mphamvu ya capacitor kuchepa chifukwa cha ukalamba, komanso chimathetsa vuto la kutuluka kwa mafuta ndi kutuluka kwa mafuta.

Kupatula apo, magwiridwe antchito achitetezo a ma capacitor owuma ndi ma capacitor amafuta ndi osiyana,

Kachipangizo ka mafuta: Kachipangizo ka mafuta kamadziwika ndi kutentha bwino komanso magwiridwe antchito abwino oteteza kutentha. Komabe, chifukwa cha mafuta omwe ali mkati mwake, akakumana ndi moto wotseguka, angathandize kuyatsa ndikuyambitsa moto. Komanso, ma capacitor a mafuta akamatengedwa kapena ali ndi mavuto ena, amachititsa kuwonongeka kwa kachipangizo ndipo mafuta amatuluka ndi kutuluka kwa madzi komwe kwatchulidwa kale m'nkhaniyi kudzachitika.

Kapu youma: Ili ndi mphamvu yotaya kutentha bwino ndipo imafuna filimu yolimba kwambiri ya polypropylene metallization. Komabe, chifukwa chodzaza mkati mwake ndi gasi kapena epoxy resin, imatha kuletsa kuyaka ngati pali moto wotseguka. Komanso, ma capacitor ouma savutika ndi kutuluka kwa mafuta kapena kutuluka. Poyerekeza ndi ma capacitor ouma, ma capacitor ouma ndi otetezeka.

Ponena za mayendedwe, poyerekeza ndi ma capacitor amafuta, ma capacitor ouma ndi opepuka okhala ndi mpweya wodzaza mkati ndi epoxy resin, kotero mayendedwe, kusamalira ndi kukhazikitsa ndi opepuka, zomwe zingathandize kuchepetsa zovuta pakuyika ndi kukonza pamlingo winawake ndikuthandizira kugwiritsa ntchito.

Kuphatikiza apo, ndi chitukuko chopitilira cha ukadaulo wopanga ma capacitor ndi ntchito za zinthu, kugwiritsa ntchito kapangidwe kouma kudzakula kwambiri ndipo pang'onopang'ono kudzalowa m'malo mwa kapangidwe ka mafuta. Kapangidwe kouma kopanda mafuta ndiye njira yopititsira patsogolo chitukuko.
