Prefabricated substations yuav muab faib ua ob hom: Standard thiab compact. Standard prefabricated substations muaj xws li qauv ZBW thiab XWB, thaum compact prefabricated substations muaj xws li qauv ZB1-336 thiab GE. 10kV khoom faib khoom nyob rau hauv prefabricated substations tsis siv circuit breakers; Cov qauv siv feem ntau suav nrog FN5-10 lossis FN7-10 qhov hloov pauv hloov nrog fuses thiab lub nplhaib network fais fab mov, txuas nrog lub siab-voltage kawg ntawm transformer los ntawm kab nyob ze. Raws li cov khoom sib txawv thiab cov khoom sib txawv, lawv feem ntau muab faib ua European-style thiab American-style prefabricated substations.
ZBW-hom Prefabricated Substation: ZBW-10/0.4kV sab nraum zoov ua ke substation yog prefabricated ua tiav cov khoom siv hluav taws xob faib hluav taws xob uas muaj lub siab -voltage compartment, transformer compartment, thiab low-voltage compartment. Nws yog tsim rau lub nplhaib network, ob npaug - kab, thiab lub davhlau ya nyob twg fais fab mov txoj kev, thiab peb txoj kev yog heev interchangeable. Cov kab nkag los siv cov kab. Lub siab-voltage compartment nta ib qho kev txhim khu kev qha, compact tsim nrog kev tiv thaiv zoo{14}} ua haujlwm tsis raug cuam tshuam, ua kom muaj kev ntseeg siab thiab ua haujlwm yooj yim thiab tu. Nws yog sib xws nrog lub davhlau ya nyob twg load keyboards, cua nplhaib lub ntsiab units, thiab SF6 nplhaib lub ntsiab units. Satons transformers tuaj yeem yog roj-immersed lossis qhuav{17}} hom. Chav tsev transformer yog qhov kub thiab txias - tswj tau thiab tuaj yeem siv cov cua cua los yog yuam cua los ntawm sab saum toj. Qhov qis-voltage compartment yog nruab nrog metering thiab reactive fais fab nyiaj them, thiab lwm yam circuits thiab tus naj npawb ntawm cov kab tawm tuaj yeem tsim raws li cov neeg siv khoom xav tau kom tau raws li cov kev xav tau sib txawv.
GE Prefabricated Substations
Qhov txawv ntawm GE prefabricated substations thiab domestic modular prefabricated substations nyob rau hauv lawv txoj kev loj hlob raws li transformers. GE prefabricated substations ua kom yooj yim rau cov qauv ntawm cov tub ntxhais transformer, siab -voltage load switch, fuses, thiab lwm yam khoom siv, muab lawv tag nrho rau hauv ib qho roj - puv lub thawv. Lawv yog cov me me, compact nyob rau hauv cov qauv, thiab nyob tsuas yog nyob ib ncig ntawm ib tug -peb qhov chaw ntawm domestic prefabricated substations ntawm tib lub peev xwm. Lub kaw ntom nti, tag nrho cov txheej txheem insulated tshem tawm qhov xav tau ntawm kev rwb thaiv tsev nyob deb, ntseeg tau tias kev nyab xeeb ntawm tus kheej. High-voltage cables txuas nrog bushings nrog zoo rwb thaiv tsev kev ua tau zoo, thiab cov bushings txuas nrog lub luj tshib- hom cable plugs, sealing cov khoom nyob rau hauv lub rwb thaiv tsev. Lub luj tshib- hom cable plugs tuaj yeem ntsaws thiab tshem tawm hauv qab lub tshuab hluav taws xob tag nrho, ua raws li kev hloov pauv. Muaj ntau hom muaj, thiab kev xaiv ceev faj yog tsim nyog rau cov ntawv thov tshwj xeeb. Phab ntsa mounts yog welded rau lub enclosure kom ruaj ntseg kev txhawb nqa - hom insulating bushing pob qij txha. Thaum lub luj tshib- hom cable ntsaws yog unplugged, nws tuaj yeem muab tso rau hauv kev txhawb nqa - hom bushing sib koom.
Kev faib tawm ntawm European thiab Asmeskas Prefabricated Substations:
Modular Substation: Modular substations tsev siab - thiab qis -voltage switchgear thiab transformers nyob rau hauv ib lub thawv hlau, nrog rau kev khiav hauj lwm txoj kev hauv nruab nrab ntawm qhov siab - thiab qis -voltage faib units. Hom prefabricated substation no kuj loj thiab tsis tshua siv tam sim no.
Combined Unit Substation: Combined unit substations tsis siv switchgear uas twb muaj lawm; Hloov chaw, qhov siab- thiab qis-voltage tswj thiab tiv thaiv cov khoom siv hluav taws xob tau ncaj qha rau hauv qhov chaw kaw, ua rau nws ib chav. Vim tias tag nrho cov qauv tsim yog kev saib xyuas -dawb, kev khiav hauj lwm txoj kev hauv tsev tsis tas yuav tsum muaj nyob rau hauv lub thawv. Qhov no txo qhov loj ntawm prefabricated substation. Hom no yog European-style prefabricated substation thiab yog dav siv.
Integrated Substation: Integrated substations tseem hu ua American -style box-hom substations. Lawv tau tsim los ntawm kev ua kom yooj yim rau cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob thiab kev tiv thaiv, kev sib koom ua ke cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob nrog lub cev hloov pauv mus rau hauv ib chav tsev hauv lub tank transformer. Hom lub thawv no- hom substation yog me dua, nrog ib lub ntim kwv yees li tib yam li cov qauv roj-immersed transformer ntawm tib lub peev xwm. Nws tsuas yog hais txog 1/3 qhov loj ntawm European -style box- hom substation ntawm tib lub peev xwm.
Ua ke, Box -hom Substations
6⁻¹/0.4(0.7)kV Prefabricated (Combined, Box{3}}type) Substation
Mining Combined (Lub thawv-hom) Substation
6⁻¹/0.4kV Prefabricated (Combined, Box{2}}hom) Substation
35/6⁻¹kV Ua ke (Box{2}}type) Substation
Cov kab tuaj yeem yog ib qho cable lossis ib qho nyiaj siv ua haujlwm insulated hlau, xaiv arbitrarily raws li kev siv ib puag ncig thiab ntau lub hom phiaj. Thaum siv los ua lub thawv rau pej xeem- hom substation, tus naj npawb ntawm cov kab qis -voltage outgoing kab nyob ntawm qhov muaj peev xwm ntawm transformer, feem ntau tsis tshaj 4 kab, thiab feem ntau 6 kab. Xwb, ib txoj kab tseem ceeb tshaj tawm tuaj yeem siv los muab lub zog rau chav faib khoom nyob ze. Thaum lub prefabricated substation yog siv los ua tus neeg siv ywj pheej, ib qho hluav taws xob hluav taws xob tuaj yeem siv tau.
