Ntawm no yog ntau hom cables, tab sis qhov yooj yim tshaj plaws yuav muab faib ua cov kab hluav taws xob tsawg thiab cov hluav taws xob siab, tab sis yuav ua li cas kom paub qhov txawv ntawm ob?Qee tus hais tias nws yog 250V, thiab qee tus hais tias nws yog 1000V.Koj paub qhov txawv ntawm high voltage thiab tsis tshua muaj siab?
Raws li Tuam Tshoj tus qauv kev lag luam, cov khoom siv hluav taws xob tau muab faib ua cov hluav taws xob siab thiab tsis tshua muaj hluav taws xob: high voltage: khoom siv hluav taws xob siab tshaj 250V rau hauv av;tsis tshua muaj hluav taws xob: khoom siv nrog voltage siab tshaj 250V rau hauv av.Raws li 2009 fais fab kab kev ruaj ntseg txoj cai, hluav taws xob ua hauj lwm yog muab faib ua high voltage thiab tsawg voltage
Cov khoom siv hluav taws xob hluav taws xob siab: qib voltage yog 1000V thiab siab dua;Cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob: qib voltage qis dua 1000V;
Feem ntau, high voltage kab hais txog 3 ~ 10kV kab;low voltage kab hais txog 220 / 380 V kab.
Cov txheej txheem kom paub qhov txawv qhov voltage ntawm high voltage hlau los ntawm liab qab qhov muag yog raws li nram no:
1. Paub qhov voltage.
Nyob rau hauv Tuam Tshoj txoj kev lag luam fais fab, cov theem voltage yog 220 V, 380 V, 1000 V, 10000 V, 35 000 V, 110 000 V, 220 000 V, 500 000 V, thiab lwm yam. Feem ntau hais lus, 220 V thiab 380 V yog xam. raws li qhov tsis tshua muaj hluav taws xob, feem ntau yog siv hluav taws xob hauv tsev;thiab saum toj no 35000 V yog cov hluav taws xob siab, feem ntau yog siv rau kev xa hluav taws xob.Nruab nrab ntawm ob yog nruab nrab siab.Nws yuav tsum tau taw qhia tias kev kov cov xaim hluav taws xob siab lossis ua haujlwm nyob hauv kab muaj kev phom sij loj.
2. txheeb xyuas cov kab hluav taws xob tsawg.
Sab nraum zoov tsis tshua muaj hluav taws xob kab muaj ntau yam ntxwv pom tseeb
1) Feem ntau, cov cement ncej tsis ntau tshaj 5 meters.
2) Lub thickness ntawm cov xov hlau yog tib yam, thiab cov xov tooj ntawm cov xov hlau muaj ntau yam ntawm 4. Qhov no yog vim cov xov hlau tsis tshua muaj hluav taws xob feem ntau siv peb theem plaub hlau.Yog tias cov yam ntxwv no muaj, nws tuaj yeem txiav txim siab tias kab hluav taws xob ntawm cov xaim yog 380 V thiab theem voltage yog 220 v. (theem voltage yog kab rau hauv av voltage, kab voltage yog voltage ntawm ob kab)
3. Txheeb xyuas cov kab nruab nrab thiab siab voltage.
Cov kab nruab nrab thiab siab voltage kuj muaj cov yam ntxwv pom tseeb
1) Yog hais tias lub thickness ntawm cov xov hlau yog tib yam, cov xov tooj ntawm cov xov hlau yog ib tug ntau yam ntawm 3. Qhov no yog vim hais tias cov kab sib kis feem ntau siv peb-theem kis tau tus mob.Yog tias cov yam ntxwv no muaj, nws tuaj yeem txiav txim siab tias cov xaim yog 10000 volts.
2) Yog hais tias lub thickness ntawm cov hlau sib txawv, cov xov tooj ntawm cov kab tuab yog ntau yam ntawm 3, thiab tsuas muaj ob lub xov hlau nyias nyias, uas yog xam tau tias yog nyob rau ntawm qhov chaw siab tshaj.Qhov no yog vim hais tias nyias hlau tsis yog siv rau kev xa hluav taws xob, tab sis rau kev tiv thaiv xob laim, tseem hu ua xob laim.Yog tias cov yam ntxwv no muaj, nws tuaj yeem txiav txim siab tias cov xaim yog cov kab hluav taws xob siab.
4. Txuas ntxiv txheeb xyuas cov kab hluav taws xob siab.
Txhawm rau txhim kho lub peev xwm kis tau tus mob, cov xaim hluav taws xob siab feem ntau siv cov khoom sib cais.Feem ntau hais lus, ib lub xaim yog siv rau ib theem.Tam sim no ob peb cov hlua hlau tau siv los hloov qhov qub.Paub qhov no, nws yog ib qho yooj yim los txiav txim qhov voltage theem ntawm cov hlau.1) Ib theem nrog ib lub xaim yog 110000 volts;2) ib theem nrog ob lub xov hlau yog 220000 volts;3) ib theem nrog plaub xaim yog 500000 volts.
Nyob rau hauv peb niaj hnub kev sib cuag nrog high-voltage kab, tab sis nyob rau hauv lub ntsej muag ntawm nruab nrab thiab tsawg-voltage kab, peb tseem yuav tsum tau ceev faj.Txhua xyoo, suav tsis txheeb cov neeg tuag los ntawm hluav taws xob poob siab, yog li tsis muaj teeb meem dab tsi ntawm cable siv, peb yuav tsum siv lub teb chaws tus qauv cable nrog kev ruaj ntseg zoo.Txhawm rau txhim kho cov khoom lag luam zoo, cov khoom lag luam raug tsim raws li nruj raws li lub teb chaws tus qauv (GB / JB) thiab International Electrotechnical Commission (IEC).Lub tuam txhab tau dhau daim ntawv pov thawj ISO9001: 2008 thoob ntiaj teb, tau txais daim ntawv tso cai tsim khoom lag luam hauv tebchaws thiab Tuam Tshoj National Compulsory Product Certification (CCC daim ntawv pov thawj).Ntawm lawv, cov thev naus laus zis ntawm XLPE cable yog nyob rau hauv lub hauv ntej ntawm kev lag luam, Yuav kom ua raws li kev tsim kho ntawm State Grid, lub tuam txhab kuj tau yuav advanced 35kV cross-linked cable ntau lawm kab, ib-kauj ruam silane cross-linked ntau lawm kab thiab lwm yam siab heev hlau thiab cable ntau lawm kab.Tsis muaj teeb meem dab tsi ntawm cable, Zhujiang cable yuav ib txwm muab rau koj qhov zoo tshaj plaws!
