XP/XWP 10-35KV 20-150KN Sab nraum zoov High voltage suspended porcelain insulator rau fais fab overhead kab

High-voltage kab disk-shaped ncua kev kawm ntawv porcelain insulators yog siv rau insulating thiab kho cov xov hlau nyob rau hauv high-voltage overhead kis tau tus mob thiab tis kab, thiab feem ntau sib sau ua ke rau hauv cov hlua insulator rau cov kab sib txawv voltage.
Ordinary insulators yog haum rau cov cheeb tsam dav dav, thiab yog tias muaj pes tsawg tus insulators tsim nyog nce, cov pa phem flashover kev ua tau zoo kuj tuaj yeem txhim kho.
Insulators muab faib ua ob hom: pob hom thiab zawj hom raws li txoj kev sib txuas.Hom zoo tib yam thiab cov tshuaj tiv thaiv kev ua qias tuaj ntawm tib lub zog hauv chav kawm txais tib lub pob thiab qhov sib txuas qhov loj, uas tuaj yeem lav tau los hloov pauv.
Qauv piav qhia:
XP —— Ordinary disk-puab zoo li ncua kev kawm porcelain insulator;
XWP —— Cov pa phem-resistant disk-zoo li raug tshem tawm porcelain insulator;
XHP —— Tswb lub kaus muaj kuab paug-resistant disk-puab ncua kev kawm porcelain insulator;
XMP — Straw kaus mom hom muaj kuab paug-resistant disk Zoo li raug tshem tawm porcelain insulators;
tus lej 1, 2, 3... yog tus lej tsim qauv;
tus lej tom qab "-" yog ntsuas qhov ntsuas hluav taws xob puas tsuaj, kN;
C tom qab tus nqi kN yog ib qho kev sib txuas qauv, thiab T yog lub pob qhov (socket cap-flat) Ko taw kev sib txuas qauv, pob thiab lub qhov (socket) txuas qauv tsis qhia.
GB / T 7253-2005 tus qauv stipulates (tus qauv tshiab):
U-Ncua tseg insulator;
Tus lej tom qab U qhia txog qhov teev electromechanical lossis mechanical puas load tus nqi, kN;
B lossis C qhia lub pob qhov (socket) lossis qhov sib txuas;
S lossis L qhia qhov luv lossis ntev qauv qhov siab, M txhais tau hais tias nruab nrab ntev, EL txhais tau tias ntev ntxiv;
P txhais tau hais tias loj creepage nrug.
