Cov kab hluav taws xob nruab nrab muaj qhov voltage ntawm 6 kV thiab 33kV.Lawv feem ntau yog tsim los ua ib feem ntawm kev tsim hluav taws xob thiab kev faib khoom siv rau ntau yam kev siv xws li kev siv hluav taws xob, petrochemical, kev thauj mus los, kev kho dej khib nyiab, kev ua zaub mov, kev lag luam thiab kev lag luam.
Feem ntau, lawv tsuas yog siv rau hauv cov tshuab uas muaj qhov hluav taws xob ntau txog 36kV thiab ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob thiab kev faib khoom sib txuas.
01.Standard
Nrog rau kev loj hlob thoob ntiaj teb kev thov rau nruab nrab voltage cables, kev ua raws li cov qauv kev lag luam tau dhau los ua qhov tseem ceeb.
Cov qauv tseem ceeb tshaj plaws rau nruab nrab voltage cables yog:
- IEC 60502-2: Qhov feem ntau siv nruab nrab-voltage cables nyob hauv lub ntiaj teb, nrog rau qhov ntsuas hluav taws xob mus txog 36 kV, ntau qhov kev tsim thiab kev sim, suav nrog ib leeg-tub ntxhais cables thiab ntau cov tub ntxhais cables;armored cables thiab unarmored cables, ob hom Armor "siv thiab hlau armor" yog suav nrog.
IEC / EN 60754: tsim los soj ntsuam cov ntsiab lus ntawm halogen acid gases, thiab lub hom phiaj los txiav txim siab cov kua qaub tso tawm thaum rwb thaiv tsev, sheathing, thiab lwm yam khoom siv hluav taws kub.
IEC / EN 60332 Kev ntsuas cov nplaim hluav taws xob thoob plaws hauv cov kab ntev thaum muaj hluav taws kub.
IEC / EN 61034 Kev ntsuas ntsuas ntsuas qhov ntsuas pa taws ntawm cov hluav taws xob hluav taws xob raws li cov xwm txheej tau teev tseg.
BS 6622: Npog cables rau cov ntsuas hluav taws xob txog li 36 kV.Nws npog cov qauv tsim thiab kev sim, suav nrog ib leeg tub ntxhais thiab ntau cov tub ntxhais cables;armored tsuas yog cables, hlau armored hom nkaus xwb thiab PVC sheathed cables.
BS 7835: Npog cables rau cov ntsuas hluav taws xob txog li 36 kV.Nws suav nrog cov qauv tsim thiab kev sim, suav nrog ib leeg-ntxhais, ntau cov tub ntxhais cables, armored cables nkaus xwb, armored nkaus xwb, tsis muaj pa taws halogen-free cables.
- BS 7870: yog cov qauv tseem ceeb heev rau cov hluav taws xob qis thiab nruab nrab hluav taws xob polymer insulated cables rau kev siv hluav taws xob tsim hluav taws xob thiab cov tuam txhab faib khoom.
02.Cov qauv thiab cov khoom siv
Nruab nrab voltage cablecov qauv tsim tuaj yeem muaj ntau qhov sib txawv thiab ntau hom.Cov qauv yog qhov nyuaj ntau dua li cov kab hluav taws xob tsawg.
Qhov sib txawv ntawm nruab nrab voltage cables thiab low voltage cables tsis tsuas yog yuav ua li cas cov cables yog tsim, tab sis kuj los ntawm cov txheej txheem tsim thiab raw khoom.
Nyob rau hauv nruab nrab voltage cables, cov txheej txheem rwb thaiv tsev yog txawv heev los ntawm cov uas tsis muaj voltage cables, qhov tseeb:
- Lub nruab nrab voltage cable muaj peb txheej es tsis txhob ntawm ib txheej: conductor shielding txheej, insulating khoom, insulating shielding txheej.
- Cov txheej txheem rwb thaiv tsev rau nruab nrab voltages yog ua tiav los ntawm kev siv CCV kab es tsis txhob siv cov kab rov tav extruders, ib yam li cov khoom siv hluav taws xob tsawg.
- Txawm hais tias lub rwb thaiv tsev muaj tib lub npe raws li cov hluav taws xob tsis tshua muaj hluav taws xob (xws li XLPE), cov khoom siv raw nws tus kheej txawv los xyuas kom meej cov rwb thaiv tsev purer.Xim masterbatches rau cov kab hluav taws xob qis tsis raug tso cai rau kev txheeb xyuas qhov tseem ceeb.
- Cov ntxaij vab tshaus hlau feem ntau yog siv rau hauv kev tsim kho cov kab hluav taws xob nruab nrab rau cov kab hluav taws xob tsis tshua muaj siab rau cov ntawv thov tshwj xeeb.
03.Test
Cov khoom siv hluav taws xob nruab nrab ntawm cov khoom siv hluav taws xob xav tau qhov kev ntsuas qhov tob los ntsuas tus kheej cov khoom thiab tag nrho cov cable raws li tag nrho cov qauv kev pom zoo rau cov khoom siv cable.Nruab nrab voltage cables raug kuaj rau lawvhluav taws xob, mechanical, khoom siv, tshuaj lom neeg thiab kev tiv thaiv hluav taws.
Hluav taws xob
Kev Ntsuas Ib Feem - Tsim los txiav txim qhov muaj nyob, qhov loj me, thiab xyuas seb qhov loj ntawm qhov tso tawm ntau tshaj li tus nqi teev rau qhov tshwj xeeb voltage.
Thermal Cycling Test – Tsim los soj ntsuam seb cov khoom siv cable teb li cas rau qhov kev hloov pauv ntawm qhov kub thiab txias.
Impulse Voltage Test - tsim los soj ntsuam seb cov khoom siv cable puas tuaj yeem tiv taus qhov hluav taws xob tawm tsam.
Voltage Test 4 Teev - Ua raws li cov kev sim ua ntu zus saum toj no kom paub meej tias qhov hluav taws xob ncaj ncees ntawm cable.
Neeg kho tshuab
Shrinkage testing - tsim los kom nkag siab txog cov khoom siv ua haujlwm, lossis cuam tshuam rau lwm yam hauv kev tsim kho cable.
Abrasion Test - Cov hlau horns me me yog quab yuam loaded raws li tus qauv thiab ces dragged horizontally raws cable nyob rau hauv ob opposite txoj kev mus rau ib tug deb ntawm 600mm.
Kev Ntsuas Kub Kub - Tsim los ntsuas seb puas muaj kev sib txuas txaus hauv cov khoom siv.
Tshuaj
Corrosive thiab Acid Gases - Tsim los ntsuas cov pa roj tso tawm raws li cov qauv kab hluav taws xob hlawv, simulate hluav taws kub, thiab ntsuas tag nrho cov khoom tsis yog hlau.
Qhov hluav taws kub
Flame Spread Test - Tsim los ntsuas thiab nkag siab txog kev ua haujlwm ntawm cable los ntawm kev ntsuas qhov sib kis ntawm cov nplaim taws los ntawm qhov ntev ntawm lub cable.
Kev Ntsuas Hluav Taws Xob - Tsim los xyuas kom meej tias cov pa luam yeeb uas tsim tawm tsis ua rau qis qis qis dua qhov ntsuas qhov tseem ceeb.
04.Kev ua haujlwm tsis zoo
Cov kab hluav taws xob tsis zoo ua rau muaj qhov tsis ua haujlwm thiab ua rau cov neeg siv khoom siv hluav taws xob kawg muaj kev pheej hmoo.
Lub ntsiab yog vim li cas rau qhov no yog ntxov ntxov laus ntawm cov cable infrastructure, tsis zoo lub hauv paus ntawm cov pob qij txha los yog cable termination systems, ua rau txo kev cia siab los yog ua hauj lwm efficiency.
Piv txwv li, kev tso tawm ib feem ntawm lub zog tso tawm yog qhov ua ntej ntawm kev ua tsis tiav, vim nws muab pov thawj tias lub cable pib deteriorate, uas yuav ua rau tsis ua hauj lwm thiab tsis ua hauj lwm, tom qab ntawd los ntawm hluav taws xob.
Cable aging feem ntau pib los ntawm kev cuam tshuam rau cable rwb thaiv tsev los ntawm kev txo cov hluav taws xob tiv thaiv, uas yog ib qho tseem ceeb qhia txog kev tsis xws luag xws li ya raws los yog huab cua hnab ris, dej ntoo, ntoo hluav taws xob, thiab lwm yam teeb meem.Tsis tas li ntawd, cais sheaths tuaj yeem cuam tshuam los ntawm kev laus, ua rau muaj kev pheej hmoo ntawm cov tshuaj tiv thaiv lossis corrosion, uas tuaj yeem ua rau muaj teeb meem tom qab kev pabcuam.
Xaiv cov kab hluav taws xob zoo uas tau sim ua kom tiav nws lub neej, kwv yees txij nkawm lossis hloov lub sijhawm, thiab zam kev cuam tshuam tsis tsim nyog.
05.Hom kuaj thiab pom zoo cov khoom
Kev xeem daim ntawv yog qhov tseem ceeb vim nws paub meej tias ib qho qauv ntawm cable ua raws li tus qauv tshwj xeeb ntawm lub sijhawm.
BASEC pom zoo cov khoom lag luam suav nrog kev saib xyuas kev tswj hwm nruj dua los ntawm kev tshuaj xyuas cov txheej txheem ntau lawm, kev tswj hwm kev tswj hwm thiab kev kuaj kab mob nruj.
Hauv cov txheej txheem kev pom zoo ntawm cov khoom, ntau cov qauv raug sim nyob ntawm seb cov kab hluav taws xob lossis ntau yam raug ntsuas.
Cov txheej txheem ntawv pov thawj BASEC nruj heev ua rau cov neeg siv kawg tias cov cables raug tsim los rau cov qauv kev lag luam uas tau lees paub, yog tsim los rau qib siab tshaj plaws thiab ua haujlwm tsis tu ncua, txo qhov kev pheej hmoo ntawm kev ua tsis tiav.
