Uninzi lwabathengi abathenga ii-capacitor zamandla kushishino ngoku bakhetha ii-capacitor ezomileyo. Isizathu semeko enjalo asinakwahlulwa kwiingenelo zee-capacitor ezomileyo ngokwazo. Xa kuthelekiswa nee-capacitor zeoyile, zineengenelo ezininzi ngokubhekiselele ekusebenzeni kwemveliso, ukhuseleko lokusingqongileyo kunye nokhuseleko. Ii-capacitor ezomileyo ngoku ziye zaba yinto ephambili kwimarike. Kutheni kucetyiswa ukusebenzisa ii-capacitor ezomileyo? Yiza kwinqaku lale veki ukuze ufunde okungakumbi ngalo.

Ii-capacitor eziziphilisayo zahlulwe zibe ziintlobo ezimbini zokwakha: ii-capacitor zeoyile kunye nee-capacitor ezomileyo. Ii-capacitor ezomileyo, njengoko igama lisitsho, i-filler ekhethiweyo luhlobo lwe-insulation olungelulo ulwelo. Ii-fillers ze-capacitor ezomileyo kushishino namhlanje ziigesi ezingasebenziyo (umz. i-sulfur hexafluoride, i-nitrogen), i-microcrystalline paraffin kunye ne-epoxy resin. Uninzi lwee-capacitor ezintywilisiweyo kwioyile zisebenzisa ioyile yemifuno njenge-arhente yokufunxa. Ii-capacitor ezomileyo azisebenzisi iikhemikhali ezinobungozi kokusingqongileyo ezifana nee-impregnants kunye neepeyinti kwinkqubo yemveliso. Xa kujongwa izinto eziluhlaza, inkqubo yemveliso, ukusetyenziswa kwamandla, ukusebenza kumjikelo wobomi kunye nokuthuthwa kunye nokulahla kokugqibela, zonke izalathiso zovavanyo lwempembelelo kokusingqongileyo zibangelwa zii-capacitor zeoyile, ezinokubizwa ngokuba yimveliso ye-capacitor enobuhlobo kokusingqongileyo.

Kukho iintlobo ezahlukeneyo zee-power capacitors kwimarike ngoku, kodwa zimbalwa kakhulu iinkampani ezisebenzisa ii-oil capacitors. Zimbini izizathu eziphambili zokuyekiswa kwee-oil capacitors.

1. Imiba yokhuseleko

Xa ii-capacitors zeoyile zisebenza, kwelinye icala, ukuvuza kweoyile kunye nokuvuza kuya kukhokelela ekuqhekekeni kwezixhobo zangaphakathi; kwelinye icala, iqokobhe liya kukhokelela ekuphumeni kweoyile kunye nokuvuza kwee-capacitors ngenxa yokubola.

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

Ioyile yokukhusela i-oyile capacitor iya kwandisa ixabiso le-asidi njengoko izinga lokwaluphala lisanda, kwaye ixabiso le-asidi liyanda ngokukhawuleza njengoko ubushushu bunyuka; ioyile yokukhusela i-oyile capacitor ikwavelisa i-asidi namanzi xa ikhula, kwaye amanzi anefuthe lokubola kwifilimu eyenziwe ngesinyithi, nto leyo ekhokelela ekubeni amandla e-capacitor yamandla anciphe kwaye ilahleko iyanda.Nokuba kukwehla komthamo we-capacitor okanye yingxaki yomngcipheko wokhuseleko, uninzi lweengxaki lubangelwa yi-insulation yeoyile. Ukuba igesi isetyenziswa njengendawo yokuzalisa, ayinakuthintela kuphela ukuncipha komthamo we-capacitor ngenxa yokwaluphala, kodwa ikwasombulula ingxaki yokuvuza kweoyile kunye nokuvuza kweoyile.

Ngaphandle koko, ukusebenza kokhuseleko kwee-capacitors ezomileyo kunye nee-oyile capacitors kwahlukile,

I-oyile capacitor: Ibonakala ngokuchithwa kakuhle kobushushu kunye nokusebenza kakuhle kobushushu. Nangona kunjalo, ngenxa yecandelo leoyile yokukhusela ngaphakathi, xa idibana nelangatye elivulekileyo, inokunceda ekutshiseni nasekubangeleni umlilo. Ngaphezu koko, xa ii-oyile capacitors zithuthwa okanye zinezinye iimeko, iya kubangela umonakalo kwi-capacitor kwaye ukuphuma kweoyile kunye nokuvuza okukhankanywe ngaphambili kwinqaku kuya kwenzeka.

I-capacitor eyomileyo: Ayisebenzi kakuhle ekuchitheni ubushushu kwaye ifuna ifilimu yokwenza i-polypropylene metallization enobukhulu obuphezulu. Nangona kunjalo, ngenxa yokuba ukuzaliswa kwangaphakathi yi-insert gas okanye i-epoxy resin, inokuthintela ukutsha xa kukho ilangabi elivulekileyo. Ngaphezu koko, ii-capacitors ezomileyo azinangxaki yokuvuza okanye ukuvuza kweoyile. Xa kuthelekiswa nee-capacitors zeoyile, ii-capacitors ezomileyo ziya kuba zikhuselekile.

Ngokuphathelele ezothutho, xa kuthelekiswa nee-oyile capacitors, ii-dry capacitors zikhaphukhaphu ngobunzima obunegesi yokuzalisa yangaphakathi kunye ne-epoxy resin, ngoko ke ukuthuthwa, ukuphathwa kunye nokufakwa kukhaphukhaphu, okunokunciphisa ubunzima bokufakelwa nokugcinwa kwinqanaba elithile kwaye kube lula ukusetyenziswa.

Ukongeza, ngophuhliso oluqhubekayo lwetekhnoloji yokuvelisa ii-capacitor kunye nokusetyenziswa kweemveliso, ukusetyenziswa kwesakhiwo esomileyo kuya kuba kuninzi ngakumbi kwaye kuya kuthatha indawo yesakhiwo seoyile kancinci kancinci. I-capacitor eyomileyo engenaoyile yindlela yophuhliso yexesha elizayo.
