Makasitomala ambiri omwe amagula ma capacitors amagetsi mumakampani tsopano amasankha ma capacitor owuma.Chifukwa cha chikhalidwe choterocho sichingasiyanitsidwe ndi ubwino wa capacitors owuma okha.Poyerekeza ndi ma capacitor amafuta, ali ndi zabwino zambiri potengera magwiridwe antchito, kuteteza chilengedwe komanso chitetezo.Ma capacitor owuma tsopano pang'onopang'ono akhala msika waukulu kwambiri.Chifukwa chiyani tikulimbikitsidwa kugwiritsa ntchito capacitor youma?Bwerani ku nkhani ya sabata ino kuti mudziwe zambiri za izo.

Ma capacitor odzichiritsa okha amagawidwa m'mitundu iwiri yomanga: ma capacitors amafuta ndi owuma.Dry capacitor, monga dzina limatanthawuza kuti chodzaza chake chosankhidwa ndi mtundu wosakhala wamadzimadzi wotsekemera.Zodzaza ma capacitor owuma m'makampani masiku ano ndi mpweya wochepa kwambiri (monga sulfur hexafluoride, nitrogen), parafini ya microcrystalline ndi epoxy resin.Ambiri mwa ma capacitor omizidwa ndi mafuta amagwiritsa ntchito mafuta a masamba ngati njira yopangira mimba.Dry capacitor sagwiritsa ntchito mankhwala owononga chilengedwe monga ma inpregnants ndi penti popanga.Poganizira zopangira, kupanga, kugwiritsa ntchito mphamvu, magwiridwe antchito pamayendedwe amoyo ndi mayendedwe komanso kutaya komaliza, zisonyezo zonse zowunikira zachilengedwe zimachitika chifukwa cha ma capacitor amafuta, omwe angatchulidwe kuti ndi ochezeka ndi chilengedwe.

Pali mitundu yosiyanasiyana ya ma capacitor amagetsi pamsika pano, koma makampani ochepa kwambiri amagwiritsa ntchito ma capacitor amafuta.Pali zifukwa ziwiri zazikulu zomwe zimasiyidwa ma capacitor amafuta.

1. Chitetezo mbali

Pamene ma capacitors a mafuta akugwira ntchito, kumbali imodzi, kutulutsa mafuta ndi kutuluka kudzatsogolera kuwonongeka kwa zigawo zamkati;Kumbali inayi, chipolopolocho chidzapangitsa kuti mafuta ayambe kutuluka ndi kutuluka kwa capacitors chifukwa cha dzimbiri.

1. Kukalamba kwa insulation kumapangitsa kuti mphamvu zama capacitor zigwe

Mafuta otsekemera a mafuta a capacitor adzawonjezera mtengo wa asidi pamene digiri ya ukalamba ikuwonjezeka, ndipo mtengo wa asidi ukuwonjezeka mofulumira pamene kutentha kumakwera;mafuta oteteza mafuta a capacitor amatulutsanso asidi ndi madzi akamakalamba, ndipo madziwo amawononga filimu yazitsulo, zomwe zimapangitsa kuti mphamvu ya capacitor ichepe ndikuwonongeka.Kaya ndi kuchepa kwa mphamvu ya capacitor kapena vuto lachitetezo chachitetezo, mavuto ambiri amayamba chifukwa cha kutsekereza mafuta.Ngati gasi amagwiritsidwa ntchito ngati malo odzaza, sangangolepheretsa mphamvu ya capacitor kuti ichepe chifukwa cha ukalamba, komanso kuthetsa vuto la kutulutsa mafuta komanso kutulutsa mafuta.

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

Mafuta capacitor: Amadziwika ndi kutentha kwabwino komanso ntchito yabwino yotchinjiriza.Komabe, chifukwa cha chigawo cha mafuta oteteza mkati, chikakumana ndi moto wotseguka, chingathandize kuyatsa ndi kuyambitsa moto.Komanso, pamene ma capacitor amafuta amanyamulidwa kapena kukhala ndi zikhalidwe zina, zimabweretsa kuwonongeka kwa capacitor ndi kutulutsa kwamafuta ndi kutayikira komwe kwatchulidwa koyambirira kwa nkhaniyi kudzachitika.

Dry capacitor: Ili ndi ntchito yoyipa yochotsa kutentha ndipo imafuna makulidwe apamwamba a filimu ya polypropylene metallization.Komabe, chifukwa kudzazidwa kwamkati ndikuyika gasi kapena epoxy resin, kumatha kuletsa kuyaka pakakhala lawi lotseguka.Kuphatikiza apo, ma capacitor owuma samavutika ndi kutulutsa kwamafuta kapena kutayikira.Poyerekeza ndi mafuta capacitors, youma capacitor adzakhala otetezeka.

Pankhani ya mayendedwe, poyerekeza ndi ma capacitor amafuta, ma capacitor owuma amakhala opepuka muunyinji ndi gasi wodzaza mkati ndi epoxy resin, kotero mayendedwe, kasamalidwe ndi kuyika kumakhala kopepuka, komwe kumatha kuchepetsa zovuta zoyika ndi kukonza mpaka pamlingo wina ndikuthandizira kugwiritsa ntchito. .

Kuphatikiza apo, ndikukula kosalekeza kwaukadaulo wopanga ma capacitor ndi kugwiritsa ntchito zinthu, kugwiritsa ntchito mawonekedwe owuma kumachulukirachulukira ndipo pang'onopang'ono kudzalowa m'malo mwa mafuta.Wouma capacitor wopanda mafuta ndiye njira yamtsogolo yachitukuko.
