Box Type Substation
Lub thawv hom substation integrates high thiab low voltage thawj cov khoom, transformer thiab lwm yam khoom siv rau hauv ob txheej, kaw, corrosion-resistant thiab movable sab nraum lub thawv hauv lub hoobkas.
Lub thawv hom substation, tseem hu ua prefabricated substation lossis prefabricated substation.Nws yog lub Hoobkas prefabricated sab hauv tsev thiab sab nraum zoov cov khoom siv hluav taws xob sib xyaw ua ke ntawm cov khoom siv hluav taws xob high-voltage switchgear, tis transformers thiab cov khoom siv hluav taws xob tsawg hluav taws xob, uas tau teeb tsa raws li qee yam kev xaim hluav taws xob.Ntawd yog, kev ua haujlwm ntawm kev hloov hluav taws xob txo qis thiab qis hluav taws xob faib hluav taws xob yog cov organically ua ke thiab nruab rau hauv cov ntaub ntawv noo noo, xeb pov thawj, plua plav pov thawj, pov thawj nas, hluav taws kub, tiv thaiv tub sab, tshav kub-insulating, tag nrho ntim. thiab movable steel qauv lub thawv, tshwj xeeb tshaj yog tsim rau hauv nroog daim phiaj kev tsim kho thiab kev hloov pauv.Nws yog lub chaw tsim khoom lag luam tshiab tom qab lub chaw nres tsheb pej xeem.Box hom substation muaj feem xyuam rau cov mines, factories, roj thiab roj teb thiab chaw nres tsheb cua.Nws hloov lub qub pej xeem fais fab faib chav tsev thiab chaw nres tsheb tis thiab dhau los ua ib qho tshiab ua tiav ntawm lub zog hloov pauv thiab cov khoom siv faib khoom.
Cov qauv ntawm lub thawv hom substation
Tag nrho cov qauv ntawm lub thawv transformer feem ntau muab faib ua peb ntu: high-voltage switchgear, transformer thiab low-voltage power distribution device.
Raws li qhov xav tau ntawm lub kaw lus, sulfur hexafluoride lossis lub tshuab nqus tsev vacuum breaker, lub nplhaib network hloov, hloov pauv thiab fuse tuaj yeem xaiv rau qhov hloov hluav taws xob siab.
Lub metering ntaus ntawv kuj tuaj yeem ntsia tau rau ntawm qhov siab-siab.Lub ntsiab hloov thiab shunt feeder hloov yog feem ntau ntsia rau ntawm qhov qis-voltage sab, thiab qee qhov tsuas yog nruab feeder keyboards ncaj qha pub rau cov neeg siv hluav taws xob tsawg-voltage terminal.Compensation capacitors thiab metering li kuj tuaj yeem ntsia tau.Kev faib tawm transformer feem ntau yog cov roj immersed lossis qhuav-hom.
Chav tsev high-voltage ntawm European lub thawv hom substation feem ntau yog tsim los ntawm high-voltage load hloov, high-voltage fuse thiab xob laim ntes, uas tuaj yeem nres thiab xa hluav taws xob thiab muaj overload thiab tiv thaiv luv luv.The low-voltage room yog tsim. Transformers feem ntau yog roj raus los yog qhuav-hom..
Muaj ob hom ntawm lub thawv, uas yog "mu" thiab "pin".Cov chav siab thiab tsis tshua muaj hluav taws xob tau teeb tsa hauv cov duab ntawm "mu" yog qhov dav, uas yog qhov yooj yim rau kev paub txog lub nplhaib network fais fab mov ntawm lub nplhaib network lossis ob chav fais fab txuas.
Cov qauv ntawm American box hom transformer yog muab faib ua pem hauv ntej thiab nram qab.Lub pem hauv ntej yog ib tug junction txee.Cov khoom siv hluav taws xob muaj xws li cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, cov khoom siv hluav taws xob siab, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob hloov hluav taws xob, roj qib ntsuas, roj ntsuas ntsuas, thiab lwm yam;Sab nraub qaum yog cov roj tank lub cev thiab lub dab dej kub.Lub transformer winding, hlau core, high-voltage load hloov thiab plug-in fuse yog tag nrho cov nyob rau hauv cov roj tank.Lub thawv txais ib tug tag nrho cov qauv kaw.Kev sib xyaw lub thawv hom substation yog tsis ntev los no tsim los ntawm domestic manufacturers thiab tsis tau siv dav.Nws yog ob txheej txheej txheej nrog cov chav siab thiab tsis tshua muaj hluav taws xob tso rau ntawm chav tsev transformer.
European hom, American hom thiab integrated box transformer muaj lawv tus kheej zoo thiab tsis zoo.European hom thawv transformer muaj lub ntim loj.Cov high-voltage thiab low-voltage keyboards thiab transformers yog tag nrho nyob rau hauv lub plhaub loj.Cov cua kub dissipation tej yam kev mob tsis zoo, thiab txhua yam khoom siv hluav taws xob yuav tsum tau nruab.Vim hais tias cov cua txias ntawm lub transformer ncaj qha dissipate tshav kub mus rau sab nraud, qhov txias txias ntawm American hom lub thawv transformer yog qhov zoo, tab sis nws cov duab yog phem dua li ntawm cov European hom, thiab nws cov tsos yog nyuaj rau phim nrog greening ib puag ncig. ntawm thaj chaw nyob.Lub thawv hloov pauv sib xyaw ua ke nyob hauv av tsawg dua, thiab nws qhov zoo thiab qhov tsis zoo yog zoo ib yam li American box transformer.Tsis tas li ntawd, American thiab integrated box transformers tsuas yog tsim nyob rau hauv Tuam Tshoj nrog lub peev xwm ntawm tsawg dua 630kVA, thaum European lub thawv hom transformers tuaj yeem ncav cuag 1250kva.
Ordinary box type substation qauv muab faib ua peb pawg:
(1) High voltage switchgear qauv;
(2) Qhuav hom transformer txee qauv;
(3) Tsawg voltage switchgear qauv.
Lub ntsiab lus ntawm thawj peb tsab ntawv cim yog:
Z-ua ke hom;B-substation;N (W) - sab hauv (sab nraum zoov, xaiv tau);X-box hom;Y-mobile.
Kev ua haujlwm thiab kev saib xyuas lub thawv hom substation
（一） Cov kev cai yooj yim rau kev ua haujlwm ntawm lub thawv hom substation
1, Hauv pem teb uas cov khoom siv hauv lub thawv tau muab tso rau ntawm qhov chaw siab dua li ntawm qhov chaw qis dua, txhawm rau tiv thaiv cov dej nag los ntawm lub thawv thiab cuam tshuam rau kev ua haujlwm.Thaum nrum lub pob zeb platform, qhov sib txawv yuav tsum tau tshwj tseg kom yooj yim rau kev tso cov cables.
2 、 Yuav tsum muaj ob qhov kev sib txuas txhim khu kev qha ntawm lub thawv thiab daim phiaj hauv av.Kev sib txuas hauv av thiab nruab nrab ntawm lub thawv transformer tuaj yeem sib koom tib daim phiaj hauv av.Cov kab sib chaws hauv av feem ntau txuas nrog hauv av pawg ntawm plaub fab ntawm lub hauv paus.
3 、 Cov khoom siv yuav tsum tsis txhob muab tso rau ib puag ncig cov khoom siv hauv lub thawv ua txhaum txoj cai kom ntseeg tau tias qhov cua ntawm cov khoom siv hluav taws xob thiab cov kev xav tau ntawm kev kuaj xyuas haujlwm.Lub thawv hom transformer yuav tsum tau txias los ntawm huab cua ncig, thiab lub qhov rooj ntawm chav tsev transformer yuav tsum tsis txhob thaiv.
