High voltage cables thiab qhov hluav taws xob tsis tshua muaj zog muaj cov qauv sib txawv, cuam tshuam lawv cov kev ua tau zoo thiab kev siv. Cov muaj kev sib xyaw nyob sab hauv cov cables qhia cov ntsiab lus tseem ceeb:
High voltage Cable qauv:
1. Tus neeg saib xyuas
2. Sab hauv semicondering txheej
3. Rwb Thaiv Tsev Txheej
4. Cov txheej txheej txheem semiconduction txheej
5. Hlau Armor
6. Sheath Txheej
Tsawg cov hluav taws xob cable qis:
1. Tus neeg saib xyuas
2. Rwb thaiv tsev txheej
3. Hlau txhab (tsis muaj nyob rau hauv ntau lub zog voltage tsawg)
4. Sheath Txheej
Thawj qhov kev sib cais ntawm cov hluav taws xob siab thiab cov xaim hluav taws xob tsis muaj zog nyob rau hauv lub xub ntiag ntawm txheej txheem semiconduction thiab cov phuam qhwv hauv cov hluav taws xob ntau. Thiaj li, siab voltage cables zoo li muaj tuab tuab tuab tuab tuab rwb thaiv tsev txheej txheej, ua rau muaj cov qauv kev tsim qauv ntxiv thiab xav tau cov txheej txheem tsim kev tsim khoom.
Semiconding txheej:
Sab hauv semiconducting txheej ua haujlwm los txhim kho hluav taws xob hluav taws xob nyhuv. Nyob rau hauv high voltage cables, qhov sib thooj ntawm tus thawj coj thiab txheej txheem rwb thaiv tsev tuaj yeem tsim cov khoob, ua rau ib nrab rho tawm uas rwb thaiv tsev. Txhawm rau txo qhov no, txheej demiconduction kev ua raws li kev hloov pauv ntawm cov hlau coj ua thiab txheej txheem rwb thaiv tsev. Ib yam li ntawd, cov txheej txheej sab nraud tiv thaiv txheej txheem tiv thaiv kev tawm tsam hauv zos ntawm cov txheej txheem rwb thaiv tsev thiab cov hlau sheath.
Kev thaiv npog txheej:
Cov hlau thaiv cov txheej hauv cov high voltage clesles serves peb lub hom phiaj tseem ceeb:
1. Fais Shielding: Tiv thaiv kev cuam tshuam sab nraud sab nraud los ntawm kev thaiv hluav taws xob ua rau muaj hluav taws xob hauv hluav taws xob.
2. Conduction ntawm Capitalitive tam sim no thaum ua haujlwm: Ua raws li txoj kev muaj peev xwm ntawm kev ua haujlwm ntws tam sim no.
3. Luv Circuit Court tam sim no txoj kev: Qhov xwm txheej ntawm kev tsis ua tiav ntawm txheej, txheej txheem kev tiv thaiv txheej muab txoj hauv kev to taub hau, txhim kho kev nyab xeeb.
Paub qhov txawv ntawm qhov hluav taws xob siab thiab cov cab tsawg heev:
1. Kev Ntsuam Xyuas Cov Qauv: Cov Khoom Siv Loj Muaj Ntau Txheej, tshwm sim thaum Txheej Ntawm Outer, Kev Tiv Thaiv, Rwb thaiv tsev, thiab tus saib xyuas. Hauv kev sib piv, cov hluavtaws tsawg feem ntau yog nthuav tawm rwb thaiv tsev lossis coj raws li kev tshem tawm ntawm txheej sab nraud.
2. Rwb thaiv cov tuab: Rwb thaiv hluav taws xob ntau tshaj, feem ntau tshaj 5 millimeters, thaum tsis tshua muaj hluav taws xob cable yog feem ntau tsis pub dhau 3 millimeters.
3. CABLE CARDINGS: Cov txheej txheej Outers ntawm cov cable feem ntau muaj cov cim qhia tshwj xeeb cable, hla kev voltage, ntev, thiab lwm yam tsis muaj tseeb.
Nkag siab cov qauv no thiab kev ua haujlwm tsis sib xws yog qhov tseem ceeb rau kev xaiv cov cable tsim nyog rau cov kev siv, kom ua tau zoo thiab kev nyab xeeb.
