PS/PSN 25-66KV 3-12.5KN Post mtundu wa porcelain insulator kwa panja mkulu voteji Mphamvu mzere

Zopangira zadothi zadothi zamizere yamagetsi apamwamba Mzere wa post insulator ndi chitsulo chosungunula chokhala ndi zotetezera chimodzi kapena zingapo zomata pazitsulo zachitsulo, nthawi zina zimakhala ndi kapu, ndipo zimatha kuikidwa pazitsulo zachitsulo.Bawuti yamutu kapena imodzi kapena mabawuti angapo amayikidwa mwamphamvu pamapangidwe othandizira.Amagwiritsidwa ntchito popangira mawaya otsekereza ndikuthandizira mawaya amagetsi a AC okhala ndi voteji mwadzina kuposa 1000V, ma frequency osapitilira 100Hz, komanso okwera osapitilira 1000m.pakati pa 40 ° C.Ma insulators a mzere (olimba) amatha kulowa m'malo mwa ma pini.Ma pin insulators ndi ma insulators amtundu wa B, omwe amatha kuwonongeka komanso kuwonongeka panthawi yogwira ntchito.Ma insulators olimba agalasi adziwononga okha panthawiyi, pomwe zoteteza zadothi sizingatero.Chifukwa chake, dipatimenti yamagetsi yamagetsi idzawononga ndalama zambiri zogwirira ntchito ndi zinthu zakuthupi kuti ziwonetsetse magetsi ndi zoyeserera zodzitetezera pazitsulo za porcelain, zomwe zili ndi zofooka zina pazachuma komanso magetsi otetezeka.Chifukwa chake, ndikukula kwaukadaulo wopanga, ma insulators a mzere (olimba) adawonekera.Insulator iyi ili ndi insulator yolimba ndipo ndi mtundu wa A insulator, kotero palibe chifukwa chodera nkhawa za kuwonongeka kwa mkati mwa insulator panthawi yogwira ntchito, yomwe ndi mwayi waukulu.
Line mzati zadothi insulators anawagawa m'magiredi asanu ndi atatu a 95, 105, 125, 150, 170, 200, 250 ndi 325kV malinga ndi oveteredwa mphezi zisonkhezero kupirira voteji mtengo;malinga ndi oveteredwa kupinda kulephera katundu mtengo, iwo anawagawa 3, 5, 8 ndi 12.5kN Maphunziro anayi;malinga ndi njira yoyikamo, imagawidwa m'mitundu iwiri: unsembe wowongoka ndi unsembe wopingasa;malinga ndi njira yolumikizira yokhala ndi mawaya apamwamba kwambiri, imagawidwa m'mitundu iwiri: mtundu womangiriza wapamwamba ndi mtundu wamtundu wapamwamba;molingana ndi njira yolumikizirana pakati pa phazi lachitsulo ndi maziko, imagawidwa kukhala Mtundu wosasunthika (kulumikizana kwa ulusi) ndi mtundu wosalekanitsidwa wachiwiri.
Kufotokozera kwachitsanzo:
PS——mzere wa post post mtundu wa porcelain insulator;
J——mtundu wa clamp, mtundu womangirira sunasonyezedwe;
N - mtunda wautali wa creepage (mtunda wamba wamba sunasonyezedwe);
nambala pambuyo pa "—" imatanthauza mphezi yodzaza ndi mphamvu yamagetsi, kV;
Nambala pambuyo pa "/" ndi mtengo wokhotakhota wolephera, kN;
Z-kuyika kowongoka, kuyika kopingasa sikuwonetsedwa;
S - kugwirizana kwa ulusi.
GB/T 21206-2007 muyezo umanena:
R——chotsekereza positi;
Nambala pambuyo pa R ikuwonetsa mtengo wokhotakhota wolephera, kN;
chilembo chotsatira E kapena J chimasonyeza kuyika kwa pulasitiki kunja kapena mkati kwa chowonjezera chachitsulo;chotsatira
zilembo T, C, ndi H zimasonyeza mtundu womangiriza pamwamba ndi chotchinga chapamwamba chomwe chimayikidwa motsatira mtundu kapena mtundu wachitsulo chapamwamba chomwe chimayikidwa mopingasa;
nambala yokwanira imawonetsa mphamvu yamagetsi yomwe yatchulidwa, nsonga ya kV.
