Dab tsi yog qhov kev ua txhaum ntawm cable thiab yuav daws lawv li cas

Cables yog ib feem tseem ceeb ntawm kev xa hluav taws xob thiab kev xa tawm, txawm li cas los xij, cable faults yog ib qho teeb meem tshwm sim hauv cov tshuab hluav taws xob.

 

Cable tsis ua hauj lwm yog hais txog qhov teeb meem txawv txav uas tshwm sim thaum siv lub cable, ua rau lub zog xa hluav taws xob raug thaiv lossis cuam tshuam. Cov kev ua tsis tiav no yuav tshwm sim los ntawm ntau yam, xws li kev laus cable, kev puas tsuaj sab nraud, thiab lwm yam.

 

Qhov zoo tshaj plaws cable txhaum-nrhiav yuav ua rau cov neeg ua haujlwm hauv thaj chaw xis nyob thiab tseem yuav txhim kho koj txoj kev ntseeg siab hauv kev kuaj xyuas kev ua haujlwm cable. Wrindu RDCD-ⅡCable Fault Locator SystemTrolley Hom, qhov tseem ceeb ntawm kev tsim kho tshiab, siv cov khoom siv hluav taws xob niaj hnub rau kev kuaj kab hluav taws xob. Zoo tagnrho rau qib voltage txog 35kV, nws precisely ntsuas ntau yam cable faults.

 

 

Feem ntau ua rau cable tsis ua hauj lwm xws li cable rwb thaiv tsev laus, rwb thaiv tsev puas, rwb thaiv tsev tawg, xoob pob qij txha, sib koom ua ke kub nce, txawv txav impedance, kab luv Circuit Court, kab qhib circuits, thiab kab tripping, thiab lwm yam.

 

Common cable txhaum hom thiab cov yam ntxwv

 

1. Cable rwb thaiv tsev tsis ua hauj lwm

 

-Insulation kev laus:

Rwb thaiv tsev laus yog ib qho teeb meem tshwm sim hauv cable tsis ua haujlwm. Kev siv lub sij hawm ntev thiab ib puag ncig tej yam yuav ua rau cable rwb thaiv tsev rau lub hnub nyoog, yog li cuam tshuam rau cov nyhuv ntawm lub zog xa mus.

 

- Rwb thaiv tsev puas:

Kev puas tsuaj rwb thaiv tsev txhais tau hais tias cov kab hluav taws xob rwb thaiv tsev yog puas los yog corroded los ntawm sab nraud quab yuam, ua rau lub hwj chim to los yog cuam tshuam.

 

- Kev puas tsuaj ntawm rwb thaiv tsev:

Kev puas tsuaj rwb thaiv tsev txhais tau hais tias cov txheej thaiv kab hluav taws xob tsis tuaj yeem tiv taus qhov dhau ntawm qhov hluav taws xob thiab tam sim no, ua rau lub zog xa hluav taws xob cuam tshuam lossis khoom siv puas tsuaj.

 

2. Cable txuas tsis ua hauj lwm

 

-Loob connectors:

Cov kab txuas xoob xoob tuaj yeem ua rau kev sib cuag tsis zoo lossis tam sim no overload, ua rau cuam tshuam hauv kev xa hluav taws xob lossis khoom siv puas tsuaj.

 

- Sib koom kub nce:

Qhov kub ntawm qhov sib txuas ntawm cable tuaj yeem tshwm sim los ntawm kev sib koom ua ke tsis zoo lossis cov khoom siv tam sim no, uas yuav tsum tau kuaj xyuas thiab kho lub sijhawm kom tsis txhob muaj hluav taws kub thiab lwm yam kev phom sij.

 

-Txoj kev sib koom ua ke impedance:

Kev sib koom ua ke impedance tsis zoo yuav ua rau tsis zoo tam sim no kis tau tus mob, yog li cuam tshuam rau kev ruaj ntseg thiab kev nyab xeeb ntawm kev xa hluav taws xob.

 

3. Cable kab tsis ua hauj lwm

 

-Cov kab hluav taws xob luv luv:

Lub voj voog luv luv ntawm cov kab hluav taws xob tuaj yeem ua rau muaj kev nyab xeeb kev nyab xeeb xws li cov khoom siv tsis zoo, kev puas tsuaj rau cov khoom siv, thiab txawm tias hluav taws kub, uas yuav tsum tau kuaj xyuas thiab tu kom raws sijhawm.

 

- Kab tawg:

Ib txoj kab tawg yuav cuam tshuam kev xa hluav taws xob thiab cuam tshuam rau lub zog hluav taws xob ruaj khov, uas yuav tsum tau kho raws sijhawm.

 

-Line tripping:

Kab tripping tej zaum yuav tshwm sim los ntawm overload, luv luv Circuit Court, thiab lwm yam. Lub fault point yuav tsum tau xyuas thiab kho raws sij hawm.

 

4. Cov kab hluav taws xob txawv txav tsis zoo

 

-Insulation tsis kam yog tsawg dhau:

Cable rwb thaiv tsev tsis kam yog tsawg dhau, uas yuav ua rau tsis zoo cable rwb thaiv tsev, yog li cuam tshuam rau kev ruaj ntseg thiab kev nyab xeeb ntawm kev xa hluav taws xob.

 

- Ntau dhau rwb thaiv tsev tsis kam:

Kev tiv thaiv kab hluav taws xob ntau dhau tuaj yeem ua rau lub zog xau lossis cuam tshuam, uas yuav tsum tau kuaj xyuas thiab kho raws sijhawm.

 

-Kev hloov pauv txawv txav hauv kev rwb thaiv tsev:

Kev hloov pauv txawv txav hauv kev rwb thaiv tsev kuj tuaj yeem tshwm sim los ntawm kev laus cable lossis lwm yam, uas yuav tsum tau tshawb xyuas thiab kho raws sijhawm.

 

Yuav ua li cas tiv thaiv thiab daws teeb meem Cable

 

1. Kev teeb tsa thiab kev saib xyuas kom zoo

 

- Tsim nyog tso thiab kho:

Thaum lub sij hawm tso thiab kho cov txheej txheem, cov txheej txheem tsim nyog thiab cov lus qhia tshwj xeeb yuav tsum tau ua raws li kom muaj kev nyab xeeb thiab ruaj khov ntawm cov cable.

 

- Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua:

Ua kom muaj kev tshuaj xyuas thiab kev saib xyuas cov kab hluav taws xob tsis tu ncua txhawm rau tshawb pom thiab daws cov teeb meem tshwm sim hauv lub sijhawm los tiv thaiv kev ua tsis tiav.

 

- Tiv thaiv kev puas tsuaj sab nraud:

Txhim khu kev tiv thaiv ntawm cables kom tsis txhob muaj kev puas tsuaj rau sab nraud, xws li kev sib tsoo, tshuaj lom neeg corrosion, thiab lwm yam.

 

2 Cable txhaum nrhiav tshuab

 

- Thermal infrared nrhiav pom:

Los ntawm kev kuaj xyuas cov kab hluav taws xob nrog lub koob yees duab infrared thermal imaging, kub qhov chaw ntawm cable faults tuaj yeem tshawb pom nyob rau lub sijhawm thiab kev ntsuas tuaj yeem ua ntej los daws qhov teeb meem.

 

- Kev kuaj ultrasonic:

Siv cov thev naus laus zis tshuab kom pom cov cables, tsis muaj suab nrov thiab yuam kev hauv cov cable tuaj yeem nrhiav tau thiab kho tau nyob rau lub sijhawm.

 

-Ground resistance detection:

Tsis tu ncua xyuas cov av tiv thaiv ntawm lub cable los xyuas kom meej qhov kev ua haujlwm ntawm cov av hauv av thiab tiv thaiv qhov tshwm sim ntawm cable faults.
