Ua rau lub hwj chim cable rwb thaiv tsev tsis ua hauj lwm

1. Rwb thaiv tsev thaiv. Qhov kev laus ntawm cov hluav taws xob hluav taws xob feem ntau tshwm sim nyob rau tom qab lub sijhawm ua haujlwm, thiab feem ntau tshwm sim hauv cov kab hluav taws xob uas tau ua haujlwm rau ntau tshaj 15 xyoo, uas ua rau muaj kev cuam tshuam loj ntawm cov kab hluav taws xob. Rwb thaiv tsev laus feem ntau muab faib ua dendritic aging, electrothermal aging thiab rwb thaiv tsev cov ntaub ntawv aging. Nyob rau hauv cov nyhuv ntawm cov hluav taws xob teb, cov huab cua sib txawv nyob rau hauv lub cable rwb thaiv tsev nruab nrab dissociates, ua rau lub rwb thaiv tsev poob. Thaum lub nruab nrab insulating yog ionized, tshuaj lom neeg xws li ozone thiab nitrate nruas yog tsim nyob rau hauv cov huab cua sib txawv, uas corrode lub insulating txheej. Nyob rau tib lub sijhawm, cov dej noo hauv cov txheej txheej rwb thaiv tsev ua rau cov rwb thaiv tsev fiber ntau sib txawv, ua rau txo qis ntawm cov rwb thaiv tsev. Overheating yuav ua rau kom lub deterioration ntawm rwb thaiv tsev. Lub ionization tshwm sim los ntawm huab cua sib txawv ntawm cov kab hluav taws xob rwb thaiv tsev txheej yuav ua rau ib nrab overheating, carbonizing cov ntaub ntawv rwb thaiv tsev thiab txo cov rwb thaiv tsev lub zog. Cable overload yog ib qho tseem ceeb ntawm cable overheating. Kev teeb tsa cable yog nyob rau hauv qhov chaw tsis zoo xws li cov chaw siv hluav taws xob siv hluav taws xob, cable tunnels, thiab cable tunnels. Tsis muaj kev siv hluav taws xob zoo rau kev sib txuas lossis hla txoj hauv kev ntawm cov cables thiab cov kav dej cua sov. Nws yuav overheat lub cable thiab ceev qhov kev puas tsuaj ntawm lub rwb thaiv tsev txheej.

2. Cov teeb meem txuas. Qhov chaw sib koom ua ke thiab lub taub hau ntawm lub davhlau ya nyob twg feem ntau ua tiav los ntawm cov neeg ua haujlwm installation ntawm qhov chaw tso. Yog tias tsis saib xyuas, nws yooj yim heev kom ua yuam kev. Cable accessory obstruction yog qhov tseem ceeb tshaj plaws ntawm cable kab thaiv, thiab nws macroscopic kev ua tau zoo yog compound interface tawm thiab accessory cov ntaub ntawv aging. Obstacles rau cable accessories feem ntau tshwm sim los ntawm kev tsim khoom tsis zoo thiab kev ua haujlwm tsis zoo ntawm cov neeg ua haujlwm. Thaum lub sij hawm tsim cov txheej txheem, tsis xws luag xws li npuas, ya raws, impurities, thiab lwm yam tshwm sim nyob rau hauv lub accessories, ua rau ib nrab paug thiab rwb thaiv tsev puas.

3. Cov teeb meem sab nrauv. Daim ntawv thov ntawm cables nyob rau hauv nruab nrab thiab high voltage hwj chim daim phiaj yog ntau thiab dav. Lub sab nrauv ntawm lub hwj chim cable yog thawj kab ntawm kev tiv thaiv los tiv thaiv cable, thiab nws txoj kev ncaj ncees yog ncaj qha cuam tshuam rau kev nyab xeeb ntawm cov qauv sab hauv thiab kev pab cuam lub neej ntawm cable.
