I-PS/PSN 25-66KV 3-12.5KN I-Porcelain insulator yohlobo lokuthunyelwe yolayini wamandla aphezulu wangaphandle

Ama-porcelain post insulators emigqa yamandla kagesi aphezulu I-insulator yeposi yomugqa iyisivikeli sensimbi esihlanganisa isivikeli esisodwa noma ngaphezulu esinamathiselwe unomphela esisekelweni sensimbi, ngezinye izikhathi sibe nekepisi, futhi singafakwa kabili esisekelweni sensimbi.I-head bolt noma eyodwa noma ama-bolts amaningana afakwe ngokuqinile esakhiweni esisekelayo.Isetshenziselwa izintambo ezivikelayo nezizisekelayo emigqeni yamandla kagesi e-AC ene-voltage yegama ephakeme kuno-1000V, imvamisa engekho ngaphezu kuka-100Hz, kanye nokuphakama okungengaphezu kuka-1000m.phakathi kuka-40°C.Izivikeli zeposi ezilayini (eziqinile) zingangena esikhundleni sezivikeli zamaphini.Ama-pin insulators ama-insulators ohlobo lwe-B, ajwayele ukuwohloka nokulimala ngesikhathi sokusebenza.Ama-insulators engilazi aqinile azozibhubhisa ngokwawo ngalesi sikhathi, kuyilapho izivikeli ze-porcelain ngeke.Ngakho-ke, umnyango wezimboni zikagesi uzosebenzisa inqwaba yabasebenzi kanye nezinsizakusebenza ukwenza ukuhlolwa kukagesi kanye nokuhlolwa kokuvimbela kuma-insulators e-porcelain, anokwehluleka okuthile ngokomnotho kanye nokunikezwa kwamandla aphephile.Ngakho-ke, ngokuthuthukiswa kobuchwepheshe bokukhiqiza, ama-insulators we-post line (oqinile) avele.Lesi sivikelo sine-insulator eqinile futhi siwuhlobo lwe-A, ngakho-ke asikho isidingo sokukhathazeka ngokuwohloka kwendawo yangaphakathi yesivikeli ngesikhathi sokusebenza, okuyinzuzo enkulu kuso.
Ama-insulators e-porcelain pillar ahlukaniswe ngamabanga ayisishiyagalombili angu-95, 105, 125, 150, 170, 200, 250 kanye nama-325kV ngokuvumelana nomfutho wombani olinganiselwe ukumelana nevelu ye-voltage;ngokwenani lomthwalo wokuhluleka ukugoba okulinganiselwe, ahlukaniswe abe ngu-3, ​​5, 8 kanye no-12.5kN Amabanga amane;ngokwendlela yokufaka, ihlukaniswe yaba izinhlobo ezimbili: ukufakwa okuqondile nokufakwa okuvundlile;ngokwendlela yokuxhuma enezintambo eziphezulu ze-voltage, ihlukaniswe yaba izinhlobo ezimbili: uhlobo olubophayo oluphezulu kanye nohlobo lwe-clamp top;ngokwendlela yokuxhuma phakathi konyawo lwensimbi nesisekelo, ihlukaniswe yaba Uhlobo olutholakalayo (uxhumano olunezintambo) kanye nohlobo olungenakuhlukaniswa lwesibili.
Incazelo yemodeli:
PS——isivikelo sobumba sohlobo lweposi;
J——uhlobo lwe-clamp, uhlobo lokubopha aluboniswa;
Ibanga elingu-N—elide le-creepage (ibanga elivamile le-creepage alibonisiwe);
inombolo engemva kokuthi "—" isho umbani ogcwele igagasi Impulse ukumelana nevelu kagesi, kV;
Inombolo engemva kuka-"/" inani lomthwalo wokuhluleka ukugoba, i-kN;
Z—ukufakwa okuqondile, ukufakwa okuvundlile akuboniswa;
S - uxhumano lwentambo.
I-GB/T 21206-2007 ejwayelekile ibeka:
R——umvikeli weposi womugqa;
Inombolo engemva kuka-R ibonisa inani lomthwalo wokuhluleka ukugoba, i-kN;
uhlamvu olulandelayo u-E noma u-J lubonisa ukufakwa kwepulasitiki yangaphandle noma yangaphakathi yesisekeli sensimbi;okulandelayo
izinhlamvu T, C, kanye no-H zibonisa uhlobo olubophayo oluphezulu kanye ne-top clamp efakwe mpo ngokulandelana noma uhlobo lwe-clamp yangaphezulu efakwe ngokuvundlile;
inombolo yesijobelelo ikhombisa umfutho wombani oshiwo wokumelana nevelu ye-voltage, i-kV ephezulu.
