Cov yam ntxwv ntawm cov hlua hluav taws xob
Feem ntau,AC fais fab qaum nrog UL ntawv pov thawjyog tsim los nqa tam sim no los ntawm ib qho chaw hauv qhov chaw siv hluav taws xob lossis hluav taws xob hluav taws xob rau nws cov neeg siv khoom. Lawv muaj cov qauv tsim zoo, raws li txoj cai, rau kev hloov tam sim no hauv 10-35 kV, tab sis muaj ntau yam uas feem ntau hloov tam sim no hauv 220-330 kV. Cov xov hlau zoo li no txuas nrog rau kev teeb tsa nyob ruaj ruaj lossis txawb.
Peb siv AC fais fab qaum qhov twg nrog UL ntawv pov thawj?
Cov txheej txheem ntawm cov tooj liab lossis txhuas lub zog qaum yuav sib txawv heev nyob ntawm seb cov hlau zoo li cas rau. Txawm li cas los xij, muaj cov khoom zoo li no uas tsis muaj khoom tuaj yeem ua yam tsis muaj:
conductors;
core rwb thaiv tsev;
plhaub;
sab nrauv npog, uas tau tso siab rau kev tiv thaiv kev ua haujlwm.
TxhuaAC fais fab qaum nrog UL ntawv pov thawjmuaj ib qho kev rwb thaiv tsev. Ib yam li ntawd, peb hu nws txoj siv rwb thaiv tsev. Kev tsim cov hlua hluav taws xob xav tau los ntawm ib mus rau tsib tus neeg xyuas pib. Cov hlab ntsha lawv tus kheej tuaj yeem yog puag ncig lossis daim duab peb sab hauv cov duab, lawv tuaj yeem ua haujlwm. Muaj cov qauv nrog ib lub xaim lossis nrog ntau cov xov hlau uas tsim cov tub ntxhais.
Koj puas tuaj yeem tau txais AC fais fab qaum nrog UL ntawv pov thawj?
Nyob rau hauv lub qaum, peb hloov lawv nyob rau hauv parallel los yog twisted. Cov chav kawm tseem ceeb tuaj yeem yog los ntawm 1st mus rau 6th. Peb lub tuam txhab yuav muab koj cov khoom siv hluav taws xob peb-core lossis plaub-core qaum (tooj liab, txhuas) ntawm tus nqi qis thiab hauv lub sijhawm luv luv.
Feem ntau muaj ib tug xoom core nyob rau hauv lub qaum, uas yuav siv sij hawm nyob rau hauv lub luag hauj lwm ntawm lub nruab nrab conductor, raws li zoo raws li lub grounding cord, uas ua hauj lwm raws li kev tiv thaiv tiv thaiv hluav taws xob xau.
Dab tsi nta AC fais fab qaum nrog UL ntawv pov thawj nqa?
Ob-coreAC fais fab qaum nrog UL ntawv pov thawjtuaj yeem tuaj nrog ib daim ntaub thaiv uas txo cov kev cuam tshuam ntawm electromagnetic teb, thiab kuj ua rau thaj tsam ib ncig ntawm tus neeg xyuas pib tam sim no sib npaug. Ntawm lwm yam, xws li ib qho screen yuav ua rau cov hlau resistant rau sab nraud influences thiab ntxiv dag zog rau nws cov rwb thaiv tsev.
Yog tias muaj kev pheej hmoo tias txoj hlua yuav raug puas vim muaj kev cuam tshuam sab nraud, nws ua rau kev txiav txim siab siv cov khoom siv armored. Niaj hnub nimno armored fais fab qaum yuav ua tiav nrog:
raug kab kab, ntsaum, nas thiab lwm yam kab tsuag;
Ntxiv mus, kev tsoo tsoo nrog lub cuab yeej thaum kho thiab lwm yam haujlwm;
pinching, pinching, thiab lwm yam.
Hom kab hluav taws xob
Hauv peb lub tuam txhab, koj tuaj yeem yuav cov khoom siv hluav taws xob sib txawv ntawm cov hlua hluav taws xob (yooj yim, nrog cov tooj liab sib txawv, nrog PVC rwb thaiv tsev, thiab lwm yam) ntawm tus nqi pheej yig. Peb muaj cov kev xaiv hauv assortment:
hluav taws-resistant - tsis raug qhib hluav taws;
Ntxiv mus, shielded - ib daim ntaub thaiv ntxiv yog muab;
roj hmab - nrog kev tiv thaiv rubberized ntxiv;
Ib yam li ntawd, armored - nrog lub plhaub ruaj khov;
nrog PVC rwb thaiv tsev - haum rau faus av;
Ib yam li ntawd, nrog cov yas rwb thaiv tsev - nyob ntawm qhov kub ntawm ib puag ncig thiab qhov yuav tsum tau muaj qhov voltage;
nrog XLPE rwb thaiv tsev.
Koj tuaj yeem yuav cov qauv tsim los ntawm peb. Koj tuaj yeem yuav saj zawg zog, acoustic, kauv, hluav taws-resistant, armoredAC fais fab qaum nrog UL ntawv pov thawj. Cov khoom tuaj yeem ua rau hauv qab dej, faus lossis kev txhawb nqa tus kheej, thiab tus nqi yuav yog ib qho txiaj ntsig zoo tshaj plaws ntawm kev ua lag luam.
Cov khoom siv thiab ntu ntu ntawm AC fais fab qaum nrog UL ntawv pov thawj
Muaj ob hom khoom siv los ntawm cov conductors tuaj yeem ua tau - aluminium thiab tooj liab. Cov ntu ntu ntawm aluminium conductors yog ncaj qha ntsig txog cov xov hlau uas yuav tsim cov tub ntxhais. Dependency yog raws li nram no:
nrog rau ib qho kev hla mus txog 35mm2(included), lub tub ntxhais los ntawm tsuas yog ib tug hlau;
Tsis tas li ntawd, nrog ib qho kev hla mus txog 300mm2, ib los yog ntau cov xov hlau muaj ntau;
Nrog rau ntu ntu ntawm 300-800mm2, ob peb cov xov hlau yuav tsum muaj ntau.
Yog tias koj yuav tsum yuav cov hluav taws xob xaim hluav taws xob rau lub roj teeb lossis rau sab nraum zoov nteg nrog tooj liab conductors ntawm tus nqi tsim khoom, nws yog ib qho tseem ceeb kom paub tias qhov xwm txheej no txawv ntawm txhuas.
Ib leeg-xaim conductors tuaj yeem nrog thaj tsam txiav mus txog 16mm2, thiab ntau cov hlau - 120-180mm2. Nrog rau qhov chaw hla ntawm 25-90mm2, ob qho tib si ib thiab ob peb xaim tuaj yeem ua tau ntau.
Nws yog ib qho tsim nyog yuav tsum paub tias cov tub ntxhais xoom muaj qhov chaw me me hla ntu. Xws li ib tug tub ntxhais nyob nruab nrab ntawm lwm tus thiab yog cim nyob rau hauv xiav nyob rau hauv cov xwm txheej ntawm peb-theem tam sim no.
Qhov zoo ntawm tooj liab fais fab qaum
Aluminium xov hlau muaj ib qho tsis tuaj yeem ntxiv - lawv muaj. Tsis tas li ntawd, aluminium nws tus kheej yog cov khoom zoo thiab pheej yig tus neeg xyuas pib uas ua haujlwm zoo ntawm txhua txoj haujlwm uas tau muab rau nws. AluminiumAC fais fab qaum nrog UL ntawv pov thawj, raws li txoj cai, yog ib qho kev tsim cov kab hluav taws xob ntev.
Txawm li cas los xij, muaj ntau qhov laj thawj uas qhia tias cov xov tooj tooj liab yog qhov zoo tshaj plaws rau kev sib txuas hauv tsev.
Qhov tseeb yog lawv:
- yas ntau dua thiab tsis tawg thaum khoov, zoo li txhuas;
- Ib yam li ntawd, lawv tsis yaj thiab tsis qaug zog, zoo li txhuas, nrog rau kev tiv thaiv kev tiv thaiv, muaj kev ntseeg ntau dua;
- ib armored fais fab qaum ua los ntawm tooj liab yuav tiv taus loads ntau dua li ib tug txhuas, txij li thaum nyob rau hauv tib tug ntoo khaub lig-section nws yuav muaj ib tug qis resistivity thiab, yog li ntawd, ib tug ntau dua hluav taws xob conductivity.
Yog li ntawd, nws yog qhov zoo tshaj plaws los yuav lub hwj chim hauv av lossis hauv av tooj liab hlau nrog txhuas uas twb muaj lawmAC fais fab qaum nrog UL ntawv pov thawjnrog rau ntu ntu ntawm 16mm2 thiab hloov cov hlua qub. Nws raug nquahu kom hloov cov khoom lag luam nrog cov ntu loj dua rau cov xaim tooj liab, tab sis nws yuav tsum nco ntsoov tias tooj liab yog kim dua li txhuas.
AC fais fab qaum nrog UL ntawv pov thawj Specifications
Lub hom phiaj ntawm cov xov hlau thiab cov peculiarities ntawm lawv cov khoom yuav cuam tshuam rau cov yam ntxwv ntawm cov khoom. Fais fab kev teeb tsa hlau tuaj yeem sib txawv ntawm ntau qhov tsis sib xws:
- cov hlab ntsha tuaj yeem yog los ntawm ib mus rau tsib;
- cov khoom tseem ceeb - aluminium los yog tooj liab;
- cross-sectional cheeb tsam ntawm lub hauv paus;
- hom hlau rwb thaiv tsev.
Nyob ntawm cov yam ntxwv no, qhov hluav taws xob uas cov hlau tiv taus, qhov kub ntawm qhov uas nws khaws nws cov kev ua tau zoo, thiab kev pabcuam lub neej yuav nyob ntawm seb.
Yuav ua li cas xaiv high voltage AC fais fab qaum nrog UL ntawv pov thawj?
Peb yuav tuaj yeem muab cov lus qhia ntxaws ntxaws txog yuav ua li cas xaiv lub zog hluav taws xob hluav taws xob hluav taws xob (nrog lossis tsis muaj hlua hauv), qhov twg cov khoom muaj ntau, tus nqi ntau npaum li cas thiab nws lub neej kev pabcuam yog dab tsi. Nws txaus los hu rau peb thiab tham nrog tus kws tshaj lij uas tsim nyog.
Ib tug kws tshaj lij yuav tuaj yeem muab cov ntaub ntawv hais txog qhov ntawdAC fais fab qaum nrog UL ntawv pov thawjua haujlwm ntawm qhov kub ntawm +50 txog -50 degrees, thiab kev pabcuam lub neej, yog tias muaj tseeb, tuaj yeem ncav cuag 30 xyoo.
Qhov siab tshaj plaws fais fab qaum tiaj tus lossis lwm yam tuaj yeem tiv taus txog li 330 kV voltages. Muaj ntau hom hlua rau rwb thaiv tsev uas yuav nyob ntawm seb hom rwb thaiv tsev. Xws li:
- ntawv - mus txog 35kV;
- roj hmab - mus txog 10kV;
- PVC - mus txog 6kV.
Xaus AC fais fab qaum nrog UL ntawv pov thawj
Nyob ntawm lub hom phiaj, hauv peb phau ntawv teev npe koj tuaj yeem nrhiav cov hom hloov pauv hloov tau ntau yamAC fais fab qaum nrog UL ntawv pov thawjrau tso rau hauv av, nplaim hluav taws (hluav taws kub-resistant), hauv armor thiab lwm yam.
Nws yog tsim nyog xaiv ib yam khoom nyob ntawm seb lub luag haujlwm yuav muab rau nws. Txhawm rau kom cov hlau ua haujlwm tau ntev, koj yuav tsum tau ua tib zoo saib xyuas cov khoom uas yuav tsim nyog rau kev ua haujlwm.
