Uninzi lwabathengi abathenga ii-capacitors zamandla kwishishini ngoku bakhetha i-capacitors ezomileyo.Isizathu saloo meko ayinakuhlukaniswa kwiinzuzo ze-capacitors ezomileyo ngokwabo.Xa kuthelekiswa ne-oil capacitors, zineenzuzo ezininzi malunga nokusebenza kwemveliso, ukukhuselwa kwendalo kunye nokhuseleko.I-Dry capacitors ngoku ngokuthe ngcembe ibe yeyona nto iphambili kwimarike.Kutheni kucetyiswa ukusebenzisa i-capacitors eyomileyo?Yiza kwinqaku lale veki ukuze ufunde ngakumbi ngalo.

Ii-capacitors zokuziphilisa zihlulwe zibe ziintlobo ezimbini zokwakha: i-oil capacitors kunye ne-capacitors ezomileyo.Ii-capacitors ezomileyo, njengoko igama lithetha ukuba isigcwalisi esikhethiweyo luhlobo olungelulo ulwelo lokugquma.Izigcwalisi zeecapacitors ezomileyo kushishino namhlanje ikakhulu ziigesi ezingenaziphethi (umz. i-sulphur hexafluoride, initrogen), iparafini eyi-microcrystalline kunye ne-epoxy resin.Uninzi lwee-capacitors ezifakwe kwioli zisebenzisa i-oyile yemifuno njenge-ejenti yokukhulelwa.Ii-capacitors ezomileyo azisebenzisi iikhemikhali ezinobungozi bokusingqongileyo ezifana ne-impregnants kunye nepeyinti kwinkqubo yokuvelisa.Ukuqwalasela izinto eziphathekayo, inkqubo yokuvelisa, ukusetyenziswa kwamandla, ukusebenza kumjikelezo wobomi kunye nokuthutha kunye nokulahlwa kokugqibela, zonke izalathisi zokuvavanya impembelelo yokusingqongileyo zibangelwa yi-oil capacitors, enokuthiwa yimveliso ye-capacitor enobume bendalo.

Kukho iintlobo ezahlukeneyo ze-capacitors zamandla kwimarike ngoku, kodwa iinkampani ezimbalwa kakhulu zisebenzisa i-oyile capacitors.Kukho izizathu ezibini eziphambili zokulahlwa kwe-oyile capacitors.

1. Imiba yokhuseleko

Xa i-oil capacitors isebenza, ngakwesinye icala, i-oil seepage kunye nokuvuza kuya kukhokelela ekuqhekekeni kwamacandelo angaphakathi;kwelinye icala, iqokobhe liya kukhokelela ekuboneni kweoyile kunye nokuvuza kwee-capacitors ngenxa yokubola.

1. Ukuguga kwe-insulation kuya kubangela ukuba amandla e-capacitors ayeke

Ioli ye-insulation ye-oil capacitor iya kwandisa ixabiso le-asidi njengoko iqondo lokuguga likhula, kwaye ixabiso le-asidi landa ngokukhawuleza njengoko ukushisa kuphakama;i-oyile ekhuselayo ye-oyile capacitor iphinda ivelise i-asidi kunye namanzi ekwaluphaleni, kwaye amanzi anefuthe elibi kwifilimu enesinyithi, ekhokelela ekunciphiseni kwamandla e-capacitor kunye nelahleko eyandayo.Nokuba kukuhla kwamandla e-capacitor okanye ingxaki yengozi yokhuseleko, uninzi lweengxaki zibangelwa yi-oyile yokugquma.Ukuba igesi isetyenziswe njengendawo yokuzalisa, ayinakunqanda kuphela umthamo we-capacitor ekunciphiseni ngenxa yokuguga, kodwa kwakhona ukusombulula ingxaki ye-oil seepage kunye nokuvuza kweoli.

Ngaphandle koko, ukusebenza kokhuseleko lwee-capacitors ezomileyo kunye ne-oyile capacitors zahlukile,

I-oyile capacitor: Ibonakaliswe ngokuchithwa kakuhle kobushushu kunye nokusebenza kakuhle kwe-insulation.Nangona kunjalo, ngenxa yecandelo le-oyile ekhuselayo ngaphakathi, xa idibana nomlilo ovulekileyo, inokunceda ukuvutha kwaye ibangele umlilo.Ngaphezu koko, xa i-oil capacitors ithuthwa okanye inezinye iimeko, iya kubangela umonakalo kwi-capacitor kunye ne-oil seepage kunye nokuvuza okukhankanywe ngaphambili kwinqaku kuya kwenzeka.

I-Dry capacitor: Inokusebenza kakubi kokutshatyalaliswa kobushushu kwaye ifuna ubukhulu obuphezulu befilimu ye-polypropylene metallization.Nangona kunjalo, ngenxa yokuba ukuzaliswa kwangaphakathi kukufaka igesi okanye i-epoxy resin, inokuthintela ukutsha xa kukho ilangatye elivulekileyo.Ngaphezu koko, ii-capacitors ezomileyo azikhathazwa yi-oil seepage okanye ukuvuza.Xa kuthelekiswa ne-oil capacitors, ii-capacitors ezomileyo ziya kukhuseleka ngakumbi.

Ngokubhekiselele kwezothutho, xa kuthelekiswa ne-oyile capacitors, i-capacitors eyomileyo ilula ngobunzima kunye negesi yokuzalisa yangaphakathi kunye ne-epoxy resin, ngoko ke ukuthutha, ukuphatha kunye nokufakwa kukhaphukhaphu, okunokunciphisa ubunzima bofakelo kunye nokugcinwa kwinqanaba elithile kunye nokuququzelela ukusetyenziswa. .

Ukongeza, ngophuhliso oluqhubekayo lwetekhnoloji yokuvelisa i-capacitor kunye nokusetyenziswa kwemveliso, ukusetyenziswa kwesakhiwo esomileyo kuya kuba kubanzi ngakumbi kwaye kuya kuthatha indawo yesakhiwo seoli ngokuthe ngcembe.I-oyile-free capacitor eyomileyo yindlela yophuhliso yexesha elizayo.
