Kev hloov pauv hauv av yog ib hom kev faib hluav taws xob lossis kev sib xyaw ua ke uas tuaj yeem ntsia tau rau hauv lub silo; nws yog qhov sib xyaw ua ke sib xyaw ua ke qhov chaw hloov pauv, hloov pauv hluav taws xob siab thiab tiv thaiv fuse thiab lwm yam, tuaj yeem ntsia tau rau hauv cov roj tank.Qauv: JB/T 10544-2006,
Lub tshuab hluav taws xob hauv av tuaj yeem siv tau rau kev siv hluav taws xob siab hluav taws xob nrog kev ncua deb, me me-load yam ntxwv hauv cov haujlwm xws li txoj kev, choj, qhov tunnels, thiab lwm yam, thiab siv los ua kev sib xyaw ua ke rau cov haujlwm uas cov kab nyiaj siv hluav taws xob txuas hauv qab lub ntiaj teb. nrog rau cov khoom siv hluav taws xob hauv zej zog.
Nws yog dav siv rau cov khoom siv hluav taws xob nrog kev ntseeg siab thiab tsis muaj kev cuam tshuam rau ib puag ncig ib puag ncig.Peb txheej ntawm 50Hz underground power supply thiab tis network nrog voltage chav kawm 10kV thiab hauv qab no tuaj yeem siv rau kev faib hluav taws xob thiab teeb pom kev zoo nyob rau hauv qhov chaw ntawm txoj kev hauv nroog, tshav dav hlau, cov choj loj, qhov, qhov loj hauv Greenland lossis chaw ua si, thiab lwm yam.
Lub prefabricated underground transformer box-hom substation yog ib tug ua tiav txheej ntawm cov cuab yeej ua ke nrog lub teeb lub thawv style hloov txee thiab prefabricated silo, uas yog preinstalled thiab tau dhau mus kuaj nyob rau hauv lub Hoobkas.Cov khoom yog tsim los ntawm ob feem ntawm cov khoom siv ob qho tib si hauv qab thiab saum av.Cov hauv qab hauv av muaj xws li prefabricated (los yog pob zeb casting ntawm qhov chaw) silo thiab underground transformer.Qhov saum toj no hauv av muaj xws li lub teeb lub thawv style (los yog ib txwm siv) sab nraum zoov swith facility thiab qhov cua nkag.Cov khoom tsim nyog rau ntau yam kev faib hluav taws xob hauv nroog, tshwj xeeb tshaj yog kev tsim hluav taws xob tsim hluav taws xob pab cuam xws li underground cable remolding.
Landscape Underground Box-type Transformer yog cov khoom tsim thiab tsim los ntawm peb lub tuam txhab.Nws yog ib tug tshiab transformer ua los ntawm underground ua ke transformer, sab nraum zoov high-low voltage txee, lub teeb-box style tiv thaiv rooj plaub thiab prefabricated underground transformer.Qhov kev hloov pauv no tuaj yeem tsim kho raws li ib puag ncig cov yam ntxwv kom ua tiav qhov sib xyaw zoo rau ib puag ncig thiab ua kom zoo nkauj ib puag ncig.
♦ Kev ua haujlwm hauv av tsawg dua yam tsis muaj qhov chaw nyob, thaj chaw zoo thiab kev teeb tsa yooj yim.
♦ Kev paub txog txoj hauv kev ntawm kev teeb tsa ze ntawm qhov nruab nrab ntawm kev thauj khoom thiab kev faib tawm hluav taws xob, txuag cov xov tooj hluav taws xob qis thiab kev nqis peev, txo qis ntawm cov xov hlau los xyuas kom muaj kev lag luam khiav lag luam.
♦ Kev tiv thaiv qib IP68, tiv thaiv kev tawg, muaj peev xwm khiav tau tag nrho rau hauv dej rau ib lub sijhawm thiab ua haujlwm zoo txhim kho kev ntseeg tau ntawm cov khoom siv hluav taws xob.
♦ Cov roj tank siv cov khoom siv hluav taws xob tag nrho, kaw tag nrho thiab cov qauv welded, ua siab ntev rau 70kPa siab yam tsis muaj dej los yog deformation los txhim kho cov kev ua haujlwm zoo ntawm cov roj tank;tsis xav tau kev rwb thaiv tsev nyob deb thiab muaj peev xwm ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm;ntiav tshwj xeeb radiator los xyuas kom meej lub zog txhua yam thiab lub peev xwm txias ntawm lub radiator.
♦ Kev sib txuas siab / qis cable tuaj yeem siv cov qauv hauv qab no:
1.Insert peb theem ib txhij mus rau peb theem cable connector nyob rau hauv lub transformer thiab mus rau lub tshwj xeeb-hom cable pob qij txha (muaj feem xyuam rau peb-theem underground transformer nrog voltage chav kawm ntawv li 10kV thiab hauv qab no, muaj peev xwm li 400kVA thiab hauv qab no)
2.Employ ib-theem cable connector thiab luj tshib-hom pluggable davhlau ya nyob twg thaiv (muaj feem xyuam rau peb-theem underground transformer nrog voltage chav kawm ntawv li 10kV thiab hauv qab no, muaj peev xwm li 1600kVA thiab hauv qab).
3.Ib hom patent insulating kua yog ntim rau hauv lub connector cais cov insulating kua los ntawm lub transformer thiab xyuas kom meej ib txwm khiav nyob rau hauv cov ntaub ntawv ntawm dej seepage vim lub capillary phenomenon.
♦ Muaj peev xwm nruab nrog roj-immersed load hloov kom paub qhov qhib thiab kaw kev ua haujlwm ntawm kev thauj khoom thiab kom paub txog lub nplhaib sib txuas thiab cov khoom siv hluav taws xob, yooj yim hloov ntawm ob txoj hauv kev uas txhim kho kev ntseeg tau ntawm lub zog hluav taws xob.
♦ Lub teeb lub thawv style hloov txee ntawm prefabricated underground transformer yog ib qho yooj yim rau nruab thiab txaus siab rau cov neeg saib rau nws cov sab nrauv siab heev, ntxiv rau, lub dav hlau tshaj tawm ntawm lub teeb lub thawv kuj tau txais txiaj ntsig zoo ntawm kev lag luam.
♦ Cov ntaub ntawv prefabricated faus transformer siv lub qhov cua;Ib qho kev sib xyaw ua ke ntawm qhov kub thiab txias tsim yog ua los ntawm kev txiav txim siab ntawm transformer, silo thiab lub teeb lub thawv.Qhov kub nce tus nqi rau lub transformer khiav ntawm rated load nyob rau hauv lub silo raws li qhov yuav tsum tau ntawm tus qauv GB 1094.2.
♦ Ib qho kev tso dej tsis siv neeg tuaj yeem ntsia tau rau hauv lub silo, tshwj xeeb ntawm dej nyab, thiab lwm yam, nws yuav cia li pib cov twj tso kua dej.
