1: Kev ua tau zoo thiab zoo ntawm XHHW hlau
1.1 Cov Nta Tseem Ceeb ntawm XHHW Hlau
Kub tiv thaiv: Rated txog 90 degree nyob rau hauv cov xwm txheej qhuav thiab 75 degree nyob rau hauv cov chaw ntub dej, XHHW hlau outperforms tso cai thhn / thwn xaim.
Tshuaj thiab noo noo tsis kam: Tus ntoo khaub lig-txuas Polyethylene (XLPE) Rwb thaiv tsev muab kev tiv thaiv zoo, thiab noo noo, qhov chaw ntub dej (XHHW hlau nyob hauv av).
Kev Ntsuas Hluav Taws Xob: Feem ntau ntsuas rau 600V, XHhw xaim yog haum rau fais fab xa thiab tswj cov voj voog.
1.2 XHHW cov xim sib txawv: TC-er thiab xhhw -2
TC-ER XHHW HLAU: Tsim los rau tais Cable Cable, qhov sib txawv no suav nrog cov qauv siv hluav taws xob hauv cov cuab yeej thiab ua raws txoj hlua daws teeb meem rau cov kev sau.
Xhhw -2: Ib qho kev hloov kho tshiab hloov rau 90 degree hauv ob qho xwm txheej ntub thiab qhuav, ua raws li cov Nec yuav tsum ua raws li.
1.3 tus nqi txiav txim siab (XHHW hlau nqe)
Tus nqi ntawm XHHW cov hlau sib txawv raws cov ntsuas cua, rwb thaiv tsev hom, thiab ntau. Cov khoom lag luam wholesale rau cov platforms zoo li yog ua rau-In-China.com muaj kev sib tw sib tw (piv txwv li cas}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.}}. Hwm ntau yam sib xws li TC-ER lossis XHHW {{}}}}} yuav raug nqi 10-20% ntau dua vim yog txhim kho durability thiab ntawv pov thawj.
2: Rwb thaiv tsev tsis kam kuaj rau XHHW hlau
Rwb thaiv tsev tiv thaiv kom muaj kev ncaj ncees ntawm XLPE rwb thaiv tsev, tiv thaiv kev phom sij hluav taws xob thiab kev phom sij. Hauv qab no yog cov lus qhia ib kauj ruam-theem:
2.1 Xaiv Cov Khoom Siv
Siv lub high-voltage rwb thaiv tsev rwb thaiv tsev tsis kam tester, xws li lubFluke 1555 Fc(10 kv) lossisMegger mit series(5-15 kV), uas yog tsim los rau kev lag luam kev lag luam. Cov yam ntxwv tseem ceeb kom ua ntej:
Muaj ntau ntau: Phim tus tester cov zis tawm rau cov xaim hluav taws xob (piv txwv li, 500v-1, {v rau 600v xhhw xaim).
Cov ntaub ntawv nkag: Cov Cuab Yeej Zoo li Fluke txuas txuas ntxiv pab keeb kwm kev taug kev ntawm kev ua haujlwm rwb thaiv tsev.
2.2 Cov Txheej Txheem Kuaj Xyuas
De-energize ntawm Circuit Court: Xyuas kom cov hlau raug txiav tawm los ntawm txhua qhov chaw siv hluav taws xob.
Ntxuav lub nplaim: Tshem cov av lossis noo noo uas yuav chrew nyeem.
Txuas tus tester: Txuas tus tes ntsuas cov coj ua rau tus neeg saib xyuas thiab rwb thaiv tsev.
Thov voltage: Rau xhhw xaim, {1- feeb feeb xeem ntawm 500v dc yog qauv. Ntau dua volfages (piv txwv li, 1, 000 v) yuav siv tau rau cov hnub nyoog lossis kev sib sau hauv av.
Sau cov txiaj ntsig tau: Kev ntsuas tsis kam nyob hauv MoGohms (Mω). IEEE 43 pom zoo kom tsawg kawg 100 mω rau cov motors; Ib yam li ntawd, XHHW cov xov hlau yuav tsum tau ntau dua qhov kev ntsuas no.
2.3 Kev kho kom haum ib puag ncig
Qhov kub cuam tshuam cuam tshuam kev nyeem ntawv. Rau txhua 10 degree nce, rwb thaiv tsev tsis kam. Kev ntsuas yog rau ib lub hauv paus ntawm 40 degree (104 degree f) siv cov qauv:
Rcorcted =} rmeasured × 2 (tbaseline-tambient) / 10rcorected {} rmeelured × 2 (tbaseline -tambient -tambient) / 10
Qhov no ua kom muaj kev sib piv muaj tseeb thaum lub sijhawm.
3: Cov ntawv thov thiab kev coj ua zoo tshaj plaws
3.1 Kev Txhim Kho Av (XHHW YAJ NYOB RAU HAUV)
Xhhw noo noo kev ua rau nws zoo tagnrho rau kev ncaj qha faus. Cov lus qhia tseem ceeb:
Siv conduit hauv corrosive xau.
Ntsuam xyuas rwb thaiv tsev rwb thaiv tsev tsis kam tshaj tawm cov txheej txheem thiab txhua xyoo los kuaj xyuas qhov tsis zoo los ntawm cov av lossis av acidity.
3.2 Kev lag luam thiab qhov chaw kub
Hauv cov chaw nrog cov twj, compressors, lossis hvac systems, tc-er xhhw hlau txo qis kev tawg.
3.3 Tus Nqi Them Nyiaj
Thaum lub Uppront XHhhW hlau nqe siab dua PVC-insulated xaiv, nws ncua lub neej ({}}}} xyoo ua pov thawj kev nqis peev.
4: Cov kev cov nyom thiab cov kev daws teeb meem
4.1 hluav taws xob zoo li qub hauv thaj chaw muaj kev puas tsuaj
Rau ib puag ncig nrog electrostatic txaus ntshai (piv txwv li cov nroj tsuag tshuaj), cov cuab yeej zoo li tusAOIP CRIME 100Schater txheeb xyuas cov rwb thaiv tsev tsis kam ntawm cov neeg ua haujlwm thiab khoom siv, kom muaj kev phom sij nyab xeeb.
4.2 PID cuam tshuam hauv Hnub Ci Kev Siv
Txawm tias XHHW tsis yog feem ntau siv hauv PV lub tshuab, cov lus qhia los ntawm covKikusui Tos7210STester hais txog qhov tseem ceeb ntawm kev kuaj qib siab (2, {2}} v) kom tiv thaiv kev ua tsis taus cov peev txheej hauv insulators.
