Kev thaiv cov cable tau thaiv ob lo lus, raws li lub npe tawm tswv yim yog qhov kis tau cable nrog hluav taws xob hluav taws xob tsim los ntawm kev thaiv txheej txheej. Qhov thiaj li hu ua "Shielding" ntawm cov qauv cable kuj yog ib qho kev ntsuas kom txhim kho kev faib khoom hluav taws xob. Tus neeg xyuas pib ntawm cov cable yog tsim los ntawm ntau cov strands ntawm cov xaim xaim, uas yog ib qho yooj yim los tsim cov txheej cua ntawm nws thiab tus neeg saib xyuas tsis du, uas yuav ua rau cov concentration ntawm hluav taws xob teb.
1. Cable Shielding Txheej
(1). Ntxiv cov ntaub thaiv npog ntawm cov khoom siv semi-conductive nyob rau saum npoo ntawm tus neeg saib xyuas, uas yog kev sib cuag nrog cov txheej txheem tso tawm ntawm tus neeg saib xyuas thiab cov txheej txheem rwb thaiv tsev. Daim txheej no ntawm daim ntaub thaiv npog yog tseem hu ua cov txheej txheem sab hauv txheej. Kuj tseem yuav kis tau rau hauv kev sib cuag ntawm cov rwb thaiv tsev nto thiab cov roj-ntawv yog yooj yim kom tawg, uas yog qhov ua rau kev tawm paug.
(2). Ntxiv cov ntaub thaiv npog ntawm cov khoom siv semi-conductive ntawm cov txheej txheem rwb thaiv tsev, uas muaj peev xwm sib cuag nrog cov hlau nplaum txheej thiab cov tshuaj rwb thaiv tsev thiab cov txaj.
Txhawm rau kom tusyees coj tus tub ntxhais thiab insulation hluav taws xob teb, 6KV thiab siab voltor txheej txheej, thiab qee qhov tsawg-voltage tsis muaj daim thaiv txheej. Nws muaj ob hom kev tiv thaiv txheej txheem: Semi-conductive shielding thiab hlau thaiv.
2. Daim hlau txiav cable
Daim thaiv npog ntawm cov cable no feem ntau yog braided rau hauv ib lub network ntawm hlau hlau lossis cov yeeb yaj kiab hlau, thiab muaj ntau txoj kev tiv thaiv thiab ntau txoj kev thaiv. Ib daim ntaub thaiv npog yog hais txog ib qho ntaub thaiv npog ib leeg los yog daim duab los ntawm daim thaiv plaub, uas tuaj yeem qhwv ib lossis ntau cov xaim. Cov Multi-shielding hom yog ib qho kev loj hlob ntawm cov tiv thaiv kev sib koom tes, thiab daim duab qhia kev tiv thaiv yog nyob rau hauv ib qho cable. Ib txhia yog siv los cais cov xov hluav taws xob hauv hluav taws xob, thiab qee qhov kev thaiv ob npaug ntawm kev thaiv kom siv los ntxiv dag zog rau cov kev thaiv kev thaiv cov ntaub ntawv. Lub tshuab kev tiv thaiv yog rau hauv av daim thaiv npog txheej kom cais cov kev cuam tshuam volfage ntawm cov hlau sab nraud.
(1) semi-tswv yim shielding
Semi-qhia cov ntaub thaiv npog txheej yog ib txwm npaj rau sab nraud ntawm cov hlau ua ke thiab cov ntaub thaiv npog txheej txheem ib txwm muaj. Daim ntaub thaiv cov ntaub thaiv ib nrab txheej yog tsim ntawm cov khoom siv semi-ua nrog cov khoom siv tsis kam muaj tsawg. Sab hauv Semi-conductive shielding txheej yog tsim los ua kom lub tsev saib xyuas thiab tsis muaj kev tawm tsam ntawm tus thawj coj thiab huab cua sib txawv los ntawm cov tub ntxhais ua si. Cov txheej txheem sab nraud-txheej txheem sib tiv thaiv txheej txheem yog qhov zoo sib xws nrog cov hlau pov tseg nrog cov hlau pov tseg nrog cov hlau pov tseg nrog cov kab nrib pleb ntawm txoj kab sib tsoo.
(2) Kev Tiv Thaiv Hlau
Rau qhov nruab nrab thiab lub zog hluav taws xob tsawg cables tsis muaj cov tsho hlau yuav tsum tau ntxiv rau cov txheej txheem SEMI-CESIDERS txheej. Cov hlau thaiv cov txheej txheej feem ntau qhwv los ntawmTooj liab Xevlossis xaim xaim xaim xaim, uas feem ntau yog lub luag haujlwm ntawm kev thaiv hluav taws xob teb.
Vim tias tam sim no los ntawm lub hwj chim cable yog tus loj, lub sib nqus daim teb yuav tsis cuam tshuam nrog cov txheej txheem tam sim no, yog li kev tiv thaiv txheej hluav taws xob tuaj yeem tiv thaiv lub pob hluav taws xob hauv cable. Tsis tas li ntawd, cov hlua ntawm daim thaiv npog txheej tuaj yeem ua si ib lub luag haujlwm hauv kev tiv thaiv av. Yog tias cov cable tseem ceeb yog puas tsuaj, cov xau dej tam sim no tuaj yeem ntws los ntawm daim thaiv Laminar ntws, xws li kev tiv thaiv kev nyab xeeb hauv kev nyab xeeb. Nws tuaj yeem pom tau tias lub luag haujlwm ntawm cov hlua thaiv hluav thaiv txheej tseem loj heev.
