Composite insulator pollution flashover kuj muaj peev xwm muaj zog, feem ntau yog vim nws qhov tshwj xeeb hydrophobic thiab hydrophobic kev txav mus los, ntau tus kws tshawb fawb hauv tsev thiab txawv teb chaws hauv kev tshawb fawb ntawm kev sib xyaw insulator hydrophobic thiab kev tsiv teb tsaws ntawm hydrophobic zog, tshwj xeeb tshaj yog nws cov hydrophobic hloov mus, sib piv muaj ntau ntau. kev txhais lus, thoob ntiaj teb me me molecules dav txhawb kev tsiv teb tsaws txoj kev xav, nws cav hais tias: qhov chaw ntawm lub insulator muaj kuab paug flashover, me me molecules tsis intersecting chains nrog rau lwm cov molecules diffuse los ntawm lub sab hauv ntawm lub insulating khoom mus rau lub insulating nto;
Los yog cov molecules me me uas sib cais los ntawm cov molecules loj tsiv mus rau qhov chaw qias neeg thiab qhwv cov qias neeg, uas muaj hydrophobicity; Nws kuj tau sib cav hais tias qhov hydrophobic txav ntawm hluavtaws insulators yog tsim los ntawm wrapping qhov kawg thiab saw ntu ntawm macromolecules nrog filth. Tsis tas li ntawd, muaj ntau qhov kev xav, kev xav sib txawv. Yog li ntawd, ua ntej kev txhim kho cov insulators nrog kev ua tau zoo dua, kev tshawb pom ntawm hydrophobicity ntawm hluavtaws insulators yog qhov tseem ceeb heev los xyuas kom meej tias kev ua haujlwm ruaj khov ntawm lub cev.
Qhov zoo tshaj plaws antifouling thiab flashover kev ua tau zoo ntawm silicone roj hmab composite insulator los ntawm qhov zoo hydrophobicity thiab cim hydrophobicity ntawm nws cov khoom insulating txheej silicone roj hmab. Lub npe hu ua hydrophobicity yog hais txog qhov saum npoo ntawm lub insulator tsis yooj yim rau kev cuam tshuam los ntawm cov dej noo, thiab cov dej nqus tau muaj nyob rau hauv daim ntawv ntawm cov hlaws dej me me uas tsis tu ncua, uas tsis tsim cov yeeb yaj kiab dej tsis tu ncua, txhawm rau txwv. tus nto to tam sim no thiab txhim kho lub flashover voltage. Lub thiaj li hu ua hydrophobic mobility yog hais txog qhov qias neeg ntawm silicone roj hmab, silicone roj hmab tuaj yeem hloov nws cov hydrophobicity mus rau qhov chaw qias neeg, yog li ntawd cov av qias neeg kuj muaj hydrophobicity.
Kev xyaum tau ua pov thawj tias hydrophobicity ntawm composite insulators hauv kev ua haujlwm yuav txo qis lossis txawm tias poob vim muaj kuab paug, av noo, tso tawm, qhov kub thiab lwm yam, uas yuav cuam tshuam ncaj qha rau kev tiv thaiv cov pa phem flashover kev ua tau zoo ntawm cov khoom siv hluav taws xob xa mus thiab kev hloov pauv thiab txawm hem lub kev nyab xeeb kev ua haujlwm ntawm qhov system. Yog li ntawd, nws yog ib qho tsim nyog los ntsuas qhov hydrophobicity ntawm cov insulators sib xyaw ua haujlwm.
Muaj peb hom kev sim hydrophobicity:
1. Hu rau Angle txoj kev:
Txoj kev ua tus cwj pwm hydrophobicity no yog los qhia txog lub xeev hydrophobicity ntawm cov insulators sib xyaw los ntawm kev sib cuag lub kaum sab xis tsim ntawm ntug dej hlaws dai rau ntawm qhov chaw insulator thiab cov khoom nto.
2. Nto nro txoj kev:
Txoj kev no qhia ncaj qha txog qhov hydrophobicity ntawm cov khoom siv hluav taws xob los ntawm kev nro ntawm cov kua sib xyaw ua ke.
3, Kev faib cov dej tsuag dej:
Kev ua haujlwm yooj yim, txoj kev no yog los ntawm kev tshawb pom cov tshuaj tsuag zoo tib yam tuaj yeem txau cov tshuaj tsuag dej rau ntawm qhov chaw insulator, yog thawj zaug tau thov los ntawm Swedish lub zog xa mus rau Kev Tshawb Fawb Lub Tsev Haujlwm. Peb tuaj yeem pom los ntawm kev soj ntsuam lub xeev ntub dej ntawm cov dej hauv qhov chaw insulator thiab sib piv cov txheej txheem kev faib tawm thiab cov duab siv, thiaj li tau txais lub xeev hydrophobicity ntawm cov khoom insulator.
Tam sim no, nyob rau hauv domestic fais fab tuam txhab uas muag, fais fab nroj tsuag thiab lwm yam insulator daim ntawv thov scenario, nrhiav kom tau ntawm insulator hydrophobic, hydraulic classification txoj kev siv ntau dav, siv ntau hydrophobic detector ntaus ntawv rau insulator cov khoom, thaum siv cov khoom, ib tug neeg teb xov tooj siv. insulating pas nrig, pas nrig los yog nyob rau hauv lub pej thuam, Los ntawm manipulating lub rwb thaiv tsev lever tej thaj chaw deb tswj ntaus ntawv yuav tsum tau ntsuas quantitatively thiab tshuaj tsuag lub nto ntawm lub insulator, tom qab lub overburden dej nto ntawm lub insulator, thiab coj cov duab no yuav raug xa mus rau ib tug tiav set. los ntawm kev tuav ib qho khoom siv tau txais, lwm tus neeg teb xov tooj los ntawm kev txheeb xyuas ntawm cov insulator hydrophobic tuav ib qho khoom siv uas tau txais hauv software tuaj yeem txiav txim siab txog qib hydrophobic insulator hauv kev sim.
