Nkag siab txog Cable Test: Cov ntaub ntawv tseem ceeb

Kev kuaj kab hluav taws xob yog qhov tseem ceeb ntawm kev ua kom ntseeg tau thiab kev ua haujlwm ntawm cov cables hauv ntau yam kev siv. Cov kev ntsuam xyuas no yog ua los ntsuas qhov kev ncaj ncees thiab kev ua haujlwm ntawm cov cables, kom ntseeg tau tias lawv ua tau raws li cov qauv tshwj xeeb thiab tuaj yeem ua tiav lawv cov haujlwm xav tau.

 

Hom Kev Ntsuas Cable

Kev sim txuas ntxiv

Ib qho ntawm cov kev ntsuam xyuas tseem ceeb koom nrog hauv kev kuaj kab hluav taws xob yog kev sim txuas ntxiv. Qhov kev ntsuam xyuas no yog tsim los xyuas kom meej tias cov conductors nyob rau hauv lub cable yog tas mus li thiab tsis muaj kev cuam tshuam los yog tawg nyob rau hauv txoj kev hluav taws xob. Nws pab txheeb xyuas qhov tsis raug ntawm lub cable uas tuaj yeem cuam tshuam nws txoj haujlwm kom raug.

Rwb thaiv tsev Resistance Test

Kev ntsuas hluav taws xob tiv thaiv hluav taws xob yog lwm qhov tseem ceeb ntawm kev kuaj kab hluav taws xob. Qhov kev ntsuas no ntsuas qhov hluav taws xob tsis kam ntawm cov conductors thiab cov rwb thaiv tsev nyob ib puag ncig lawv. Nws pab txiav txim siab qhov ua tau zoo ntawm cov rwb thaiv tsev tiv thaiv tam sim no los yog luv luv Circuit Court.

Kev ntsuas hluav taws xob siab

Kev ntsuas hluav taws xob siab yog ua los ntsuas lub peev xwm ntawm cov kab hluav taws xob tiv thaiv hluav taws xob siab yam tsis muaj kev puas tsuaj. Qhov kev sim no yog qhov tseem ceeb rau kev kuaj xyuas qhov tsis muaj zog ntawm cov rwb thaiv tsev uas tuaj yeem ua rau hluav taws xob tsis zoo lossis muaj kev nyab xeeb.

Polarization Index Test

Polarization Performance index kuaj yog siv los ntsuas qhov rwb thaiv tsev ntawm cov kab hluav taws xob los ntawm kev sib piv cov rwb thaiv tsev tiv thaiv ntawm qhov sib txawv voltage. Nws muab kev nkag siab zoo rau kev noj qab haus huv tag nrho ntawm cov kab hluav taws xob rwb thaiv tsev.

Time Domain Reflectometry (TDR) Kev Xeem

TDR kuaj yog ib qho txheej txheem siv los txheeb xyuas thiab nrhiav qhov tsis raug hauv cov kab hluav taws xob, xws li kev tawg lossis impedance variations, los ntawm kev txheeb xyuas cov teeb liab tshwm sim. Txoj kev no tso cai rau kom meej meej hauv cheeb tsam ntawm cable faults, ua kom yooj yim rau kev kho lossis hloov.

Optical Time Domain Reflectometry (OTDR) Kev Xeem

Hauv fiber ntau optical cables, OTDR kuaj yog ua hauj lwm los ntsuam xyuas qhov muag tsis pom thiab pom tej yam tsis xws luag los yog discontinuities raws qhov ntev ntawm cov fiber. Qhov kev sim no yog qhov tseem ceeb rau kev ua haujlwm kom zoo ntawm cov fiber ntau optical hauv cov ntaub ntawv xa mus thiab kev sib txuas lus sib txuas lus.

 

Qhov tseem ceeb ntawmKabKev sim

Kev kuaj kab hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm ntawm cov cables thoob plaws ntau yam kev lag luam thiab kev siv. Los ntawm kev ua kom tiav thiab kev ntsuam xyuas, cov kev pheej hmoo, kev ua yuam kev, thiab cov teeb meem kev ua haujlwm tuaj yeem txheeb xyuas thiab daws cov teeb meem, txo qis qis thiab ua kom pom kev ua haujlwm zoo.

 

Xaus

Hauv kev xaus, kev ntsuam xyuas cable suav nrog ntau yam kev ntsuas tseem ceeb txhawm rau ntsuas kev ncaj ncees, kev ua tau zoo, thiab kev nyab xeeb ntawm cables. Los ntawm kev siv cov kev ntsuam xyuas no, qhov muaj peev xwm tsis zoo thiab qhov tsis zoo hauv cov kab hluav taws xob tuaj yeem txheeb xyuas thiab kho, ua rau muaj kev ntseeg siab thiab ua haujlwm ntawm cable systems.
