Hauv kev faib hluav taws xob, xaiv txoj cainruab nrab voltage switchgeartseem ceeb heev. Nws ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab txuag nyiaj dhau sijhawm. Muaj ntau hom kev xaiv. Paub txog cov yam ntxwv tseem ceeb ntawm hom tseem ceeb-zoo li Gas Insulated Switchgear (GIS), Ring Main Unit (RMU) Switchgear (feem ntau hu uanplhaib network txee), thiab KYN Hlau -Clad Switchgear- yuav pab koj nrhiav cov cuab yeej tsim nyog rau koj qhov project. Hauv qab no yog cov lus qhia yooj yim los pab koj xaiv qhov no.
Pib nrog Cov Qauv Tseem Ceeb rau Kev Xaiv Nruab Nrab Voltage Switchgear
Ua ntej saib cov kev hloov pauv tshwj xeeb, tshem tawm plaub qhov kev xav tau yooj yim kom nqaim koj cov kev xaiv:
1. Voltage Level thiab System Settings
Ua ntej, paub meej tias koj lub cev qhov ntsuas hluav taws xob (piv txwv li, 10kV, 35kV) thiab luv luv - lub peev xwm tam sim no. Piv txwv li, 35kV systems feem ntau xav tau cov khoom siv nrog kev rwb thaiv tsev zoo dua thiab muaj peev xwm tawg, thaum lub tshuab 10kV muaj ntau txoj kev xaiv. Kojnruab nrab voltage switchgearyuav tsum phim cov chaw no kom tsis txhob overloads los yog rwb thaiv tsev teeb meem.
2. Cov xwm txheej ib puag ncig
Sab nraum zoov lossis tawv ib puag ncig (qhov siab siab, qhov chaw ntub dej ntawm ntug dej hiav txwv, muaj kuab paug) xav tau kev tiv thaiv zoo. Cov qauv ntim ntim ua haujlwm zoo dua ntawm no. Hauv tsev, qhov chaw huv si tuaj yeem siv cov qauv qhib ntau dua.
3. Kev txwv qhov chaw thiab kev teeb tsa
Cov chaw hauv nroog lossis cov chaw hauv av feem ntau muaj qhov chaw me me, yog li kev cog lus yog qhov tseem ceeb. Ntawm qhov tod tes, kev cob qhia kev lag luam nrog ntau chav yuav mob siab rau kev saib xyuas yooj yim dua li qhov loj.
4. Kev tu thiab lub neej xav tau
Cov chaw tseem ceeb xws li tsev kho mob lossis cov chaw khaws ntaub ntawv xav tau cov cuab yeej siv uas xav tau kev saib xyuas me ntsis thiab ntseeg siab heev - qhov no txo qis sijhawm poob. Cov phiaj xwm ntawm cov peev nyiaj yuav sib npaug cov nqi pib nrog ntev - cov nuj nqis tu ncua sij hawm.
Match Scenarios rau Switchgear Hom: GIS, Nplhaib Network Txee, thiab KYN
1. Gas Insulated Switchgear (GIS): Kom txuag chaw thiab ib puag ncig nyuaj
Gas Insulated Switchgearyog paub rau nws heev compact tsim. Nws kaw cov busbars, Circuit Court breakers, thiab disconnectors nyob rau hauv ib lub thawv hlau kaw uas muaj SF₆ roj. Cov pa roj no yog 100 npaug ntau dua li cov rwb thaiv tsev tshaj huab cua. Cov qauv kaw tag nrho txhais tau tias Gas Insulated Switchgear tsis cuam tshuam los ntawm plua plav, ya raws, lossis muaj kuab paug. Nws yog qhov zoo tshaj plaws rau qhov siab - thaj chaw siab, thaj chaw ntug dej hiav txwv, lossis cov nroog uas tsis tshua muaj av (nws qhov loj me tsuas yog 10-30% ntawm cov huab cua ib txwm muaj- cov khoom siv insulated).
Thaum tus nqi pib yog siab dua, nws xav tau kev saib xyuas me ntsis. Nws yog qhov zoo raunruab nrab voltage switchgearsiv qhov kev ntseeg siab thiab txuag chaw yog qhov yuav tsum tau-zoo li subway substations lossis hauv plawv nroog cov tsev lag luam.
2. Nplhaib Network Txee (RMU Switchgear): Rau Kev Sib Txuas Sib Txuas Sib Txuas
A nplhaib network txee(RMU) yog tsim rau lub nplhaib - zoo li lub zog faib tshuab. Nws muaj ob - txoj kev fais fab mov thiab kho qhov yuam kev ceev. Feem ntau compact thiab haum nrog SF₆ load switches los yog lub tshuab nqus tsev vacuum breakers, nws ua hauj lwm zoo nyob rau hauv lwm yam kev faib cov xwm txheej-xws li cov chaw nyob, industrial parks, los yog lub thawv- hom substations.
Lub nplhaib network txee sib npaug tus nqi thiab kev ua haujlwm: nws cov qauv tsim tso cai rau kev sib xyaw ua ke kom tau raws li cov ceg sib txawv xav tau, thiab nws qhov me me haum yooj yim hauv qhov chaw nruj. Rau nruab nrab voltage switchgear siv uas tsom rau kev faib yooj yooj yim thiab kev tswj tus nqi-xws li txuas ntau tus neeg siv kawg- nws yog qhov kev xaiv zoo tshaj plaws.
3. KYN Hlau-Clad Switchgear: Rau Kev Kho Kom Yooj Yim thiab Kev Ntseeg Siab
KYN Hlau-Clad Switchgear yog qhov kev xaiv txhim khu kev qha rau nruab nrab voltage switchgear siv. Nws muaj tag nrho cov txheej txheem hlau sib cais rau hauv cov khoom sib cais (busbar, Circuit Court breaker, cable, thiab chav tswj). Nws tshem tawm Circuit Court breaker tsim tso cai rau koj ua kev saib xyuas yam tsis tau kaw tag nrho lub cev - qhov no yog qhov zoo dua rau cov chaw xws li cov chaw tsim khoom lossis cov chaw tsim hluav taws xob uas cov nqi poob qis heev.
Nrog rau cov khoom siv dag zog muaj zog thiab ua raws li "tsib-kev tiv thaiv" cov qauv kev nyab xeeb, KYN switchgear ua haujlwm tsis tu ncua hauv ib puag ncig sab hauv. Nws txhawb ntau yam kev tiv thaiv kev teeb tsa (overcurrent, ceev- tawg, qis-voltage tiv thaiv) thiab yooj yim los nthuav. Qhov no ua rau nws tsim nyog rau kev faib khoom nruab nrab lossis theem nrab uas xav tau lub sijhawm ntev - kev ntseeg siab thiab kev pabcuam yooj yim.
