Dab tsi yog qhov txiaj ntsig tiag tiag ntawm kev ua qias tuaj ntawm cov insulators sib xyaw? Txhawm rau ua kom tiav cov txiaj ntsig ntawm kev ua qias tuaj, nws yog ib qho tsim nyog yuav tsum nkag siab txog tag nrho cov qauv ntawm cov khoom siv insulator.
Tag nrho cov pas nrig hom tsim lub tswv yim ntawm kev sib xyaw insulator muaj cov qauv tsim, zoo thiab qhov hnyav tag nrho, uas yog 1 / 10 ntawm cov qib tiaj tus porcelain thiab iav insulator. Kev thauj mus los thiab kev teeb tsa tau nrawm heev. Haum rau thaj chaw av nkos, cov cuab yeej siv tshuab siab, lashen load, txoj kev ntev thiab kev cog lus. Lub flashover ua haujlwm voltage yog 30 feem pua - 50 feem pua siab dua ntawm cov qib tiaj tus porcelain thiab iav insulators. Nws muaj cov yam ntxwv ruaj khov nyob rau hauv kev ua haujlwm kub ntawm - 60 degree - ntxiv rau 200 degree ; Kev xaiv tsim lub tswv yim ntawm hom tsis thermal tawg tsis tas yuav ntsuas xoom tus nqi hauv kev ua haujlwm.
(1) Cov yam ntxwv zoo turbidity. Cov txheej txheej ntawm cov khoom siv raw ntawm silicone kaus npog tsis yog tsuas yog hydrophobic thaum lub sijhawm ntawd, tab sis kuj tuaj yeem kho tau thaum lub hydrophobicity poob ib ntus raws li kev ua haujlwm ntawm txoj kev. Cov dej tee tshwm sim nyob rau saum npoo ntawm cov khoom siv raw, thiab feem ntau ntawm daim nyias nyias ntawm cov silica gel kua nqos cov turbidity, yog li inhibiting lub melting ntawm zoo ionic tshuaj nyob rau hauv cov dej, txo cov leakage tam sim no thiab txhim kho cov turbidity flashover ua hauj lwm voltage. Cov khoom no tau khaws cia txawm tias thaum cov khoom siv silica gel yog embrittled. Yog li ntawd, kev ntseeg siab ntawm kev thauj mus los ntawm electromagnetic zog yog txhim kho, thiab kev tu thiab kev tiv thaiv cov nqi ntawm cov insulators raug txo kom tsawg.
(2) Zoo heev UV tsis kam, corrosion kuj,
(3) Qhov hnyav tag nrho ntawm 110kV / 100kN sib xyaw cov pas nrig ntev nrog cov lus qhia me me thiab lub teeb tsuas yog 12 feem pua ntawm 70kN ceramic insulator. Lub teeb tag nrho hnyav heev txuag tus nqi ntawm kev teeb tsa thiab kev thauj mus los. Nws zoo li tsis xav tau cov cuab yeej nqa nqa, thiab yog qhov tsim nyog rau kev saib xyuas kev kub ceev thiab kev tsim kho, kev tiv thaiv thiab kev saib xyuas ntawm txoj kev hauv cov chaw tsis zoo uas cov tsheb tsis siv tau; Nws tuaj yeem ua kom yooj yim rau cov qauv ntauwd thiab tso cai rau lub sijhawm loj (txo tag nrho cov yees); Nws kuj qhia tau hais tias cov qauv rau txoj kev loj hlob ntawm txoj kev compact.
(4) Lub sijhawm tsim khoom thiab khoom siv yog luv dua li ntawm cov insulators ceramic
(5) Nws yog ib qho tseem ceeb los xyuas qhov pes tsawg tus nqi ntawm grounding resistance.
(6) Tsis muaj qhov tsis xws luag, cov yam ntxwv zoo li no tsis yog tsuas yog muaj txiaj ntsig zoo rau kev teeb tsa thiab kev thauj mus los, tab sis kuj txhawb nws txoj kev tiv thaiv hluav taws xob sib cais, thiab nws lub peev xwm ua haujlwm ntau dua li ntawm ceramic insulator ntxhua khaub ncaws.
