PS/PSN 25-66KV 3-12.5KN Thumela uhlobo lweporcelain insulator yombane wangaphandle Umgca wamandla aphezulu

I-porcelain post insulators kwi-high-voltage imigca I-insulator ye-line post insulator yintsimbi ye-insulator equkethe enye okanye i-insulators edibeneyo ngokusisigxina kwisiseko sesinyithi, ngamanye amaxesha i-cap, kwaye inokuphinda ifakwe kwisiseko sesinyithi.Intloko yentloko okanye enye okanye iibholiti ezininzi zifakwe ngokungqongqo kwisakhiwo esixhasayo.Isetyenziselwa i-insulating kunye nokuxhasa iingcingo kwiintambo zamandla ze-AC ezine-voltage yegama ephezulu kune-1000V, i-frequency engekho ngaphezulu kwe-100Hz, kunye nobude obungekho phezulu kune-1000m.phakathi kwama-40°C.Ii-insulators ze-line (eziqinileyo) zinokuthatha indawo ye-pin insulators.I-pin insulators zi-insulators zohlobo lwe-B, ezivame ukuphuka kunye nomonakalo ngexesha lokusebenza.Ii-insulators zeglasi eziqinileyo ziya kuzitshabalalisa ngeli xesha, ngelixa i-porcelain insulators ayiyi.Ke ngoko, isebe leshishini lombane liya kuchitha uninzi lwabasebenzi kunye nezixhobo zokusebenza ukwenza uvavanyo lombane kunye neemvavanyo zokuthintela kwi-porcelain insulators, eneziphene ezithile ngokubhekiselele kuqoqosho kunye nonikezelo lwamandla olukhuselekileyo.Ngoko ke, ngokuphuhliswa kobugcisa bokuvelisa, i-insulators ye-post line (eqinile) ibonakala.Esi sigqubuthelo sinesigqubuthelo esiqinileyo kwaye luhlobo A lwe-insulator, ngoko ke akukho mfuneko yakuba nexhala malunga nokuqhekeka ngaphakathi kwendawo ekhuselayo ngexesha lokusebenza, eyona nto iluncedo kuyo.
Ii-insulators ze-porcelain ze-line zahlulwe zaba ngamabakala asibhozo angama-95, 105, 125, 150, 170, 200, 250 kunye ne-325kV ngokwemilinganiselo yombane yokumelana nexabiso lombane;ngokwexabiso lomthwalo wokungaphumeleli ukugoba, zahlulwe zibe yi-3, 5, 8 kunye ne-12.5kN Amabanga amane;ngokwendlela yokufakela, ihlulwe ibe ziindidi ezimbini: ukufakwa ngokuthe nkqo kunye nokufakwa okuthe tye;ngokwendlela yokudibanisa kunye neengcingo eziphezulu ze-voltage, zihlulwe zibe ziindidi ezimbini: uhlobo olubophezelayo oluphezulu kunye nohlobo oluphezulu lwe-clamp;ngokwendlela yokudibanisa phakathi kweenyawo zensimbi kunye nesiseko, ihlulwe ibe yiNdidi edibeneyo (uxhulumaniso lwemisonto) kunye nohlobo olungenakuhlukaniswa.
Inkcazo yomzekelo:
I-PS——i-porcelain type ye-porcelain insulator;
J——uhlobo lokubamba, uhlobo lokubopha aluboniswa;
N-umgama omde we-creepage (umgama oqhelekileyo we-creepage awuboniswanga);
inani elisemva "—" lithetha umbane wamaza ombane apheleleyo I- Impulse imelana nexabiso lamandla ombane, kV;
Inani elisemva kwe "/" lixabiso lomthwalo wokusilela ukugoba, kN;
U-Z-ufakelo oluthe tye, ufakelo oluthe tye aluboniswa;
S-uqhagamshelwano ngomsonto.
Umgangatho we-GB/T 21206-2007 umisela:
R——isigqubuthelo sokuxhoma;
Inani elisemva kwe-R libonisa ixabiso lomthwalo wokusilela ukugoba, i-kN;
unobumba olandelayo u-E okanye u-J ubonisa ukufakwa kweplastiki yangaphandle okanye yangaphakathi yesixhobo sentsimbi;elandelayo
oonobumba u-T, u-C, no-H babonisa uhlobo oluphezulu lokubopha kunye nesibambiso esiphezulu esifakwe ngokuthe nkqo ngokulandelelanayo chwetheza okanye uhlobo lwesibambiso esiphezulu esifakwe ngokuthe tye;
inombolo yesimamva ibonisa impembelelo yombane echaziweyo ukumelana nexabiso lamandla ombane, incopho ye-kV.
