I-13KN PW-33-Y Uhlobo lwePin yeVoltage ePhakamileyo ye-Porcelain Insulator

Inkcazo yeMveliso

I-insulator ye-pin licandelo elisetyenziselwa ukuxhasa okanye ukuxhoma ucingo kunye nokwenza isigqubuthelo sombane phakathi kwenqaba kunye nocingo [1].Uhlobo lwepini ye-ceramic ye-ceramic eqhelekileyo i-porcelain iinxalenye ze-porcelain kunye nentsimbi etyhidiweyo idityaniswe kunye ne-adhesive ye-samente, kwaye umphezulu weendawo ze-porcelain zigqunywe ngoluhlu lwe-glaze ukuphucula ukusebenza kwe-insulator.
Ii-insulators ziya kuba namandla okwaneleyo okugquma kunye namandla omatshini.Ngexesha lokusebenza, ii-insulators aziyi kumelana kuphela nesenzo sombane osebenzayo kunye ne-voltage engaphezulu, kodwa zikwanokumelana okwaneleyo nokhukuliseko lokungcola kweekhemikhali, kwaye zinokuqhelana nefuthe lokutshintsha kobushushu kunye nokusingqongileyo.

Ukusebenza kwemveliso

Iimpawu ezisisiseko ze-pin insulators ziquka umbane, oomatshini kunye neempawu ze-thermal.Ukongezelela, kukho ukuchasana nokusingqongileyo kunye nokuchasana nokuguga kunye nezinye iimpawu.

(1) Ukusebenza kombane: Ukukhutshwa okutshabalalisayo ecaleni kwendawo yokugquma kubizwa ngokuba yi-flashover, kwaye uphawu lwe-flashover luyinto ephambili yokusebenza kombane kwizithinteli.Kumanqanaba ombane ahlukeneyo, ii-insulators zineemfuno ezahlukeneyo zokunyamezela i-voltage, kubandakanya ukunyamezela amandla ombane owomileyo kunye nokunyamezela kwamandla ombane, ukunyamezela umbane wempembelelo yombane, ukunyamezelwa kombane wempembelelo yamaza ombane, kunye nokunyamezela amandla ombane.Ukuze ugweme ukuphuka ngexesha lokusebenza, i-voltage yokuchithwa kwe-insulator iphezulu kune-flashover voltage.Kuvavanyo lwasefektri, uhlobo lokwaphuka kwe-porcelain insulator ludla ngokudlula kuvavanyo lwentlantsi, oko kukuthi, amandla ombane aphezulu anyuswe ukuze kwenzeke iintlantsi rhoqo kumphezulu wokugquma, kwaye ugcine ixesha elithile ukuze ubone ukuba yaphukile.Ezinye ii-insulators kufuneka ziye kuvavanyo lwe-corona, uvavanyo lophazamiseko lukanomathotholo, uvavanyo lokukhutshwa kancinci kunye novavanyo lwelahleko ye-dielectric.Amandla ombane we-insulators kwiindawo eziphakamileyo eziphakamileyo ayancipha ngenxa yokunciphisa ubuninzi bomoya, ngoko ke amandla abo okumelana nawo kufuneka anyuswe xa aguqulelwa kwiimeko eziqhelekileyo zomoya.I-voltage ye-flashover ye-insulators engcolileyo xa ichaphazeleka ngokufuma iphantsi kakhulu kune-voltage yabo eyomileyo nemanzi.Ke ngoko, ukugqunyelelwa kufuneka kuqiniswe okanye izithinteli ezimelana nongcoliseko kufuneka zisetyenziswe kwiindawo ezingcolisekileyo, kwaye umgama we-creepage (umlinganiselo womgama we-creepage ukuya kwi-voltage elinganisiweyo) kufuneka ube phezulu kune-insulators eziqhelekileyo.Xa kuthelekiswa ne-AC insulators, i-DC insulators inokusasazwa kakubi kombane, i-adsorption yamasuntswana ongcoliseko kunye ne-electrolysis, i-voltage ephantsi ye-flashover, kwaye ngokubanzi ifuna uyilo olukhethekileyo lwesakhiwo kunye nomgama omkhulu we-creepage.
