Hauv10 kVrau35kv ua nruab nrab -voltagecov phiaj xwm kev faib hluav taws xob,huab cua-insulated switchgear (AIS) thiabgas-insulated switchgear (GIS) yog ob yam khoom tseem ceeb hauv kev lag luam no. Lawv kuj yog cov khoom siv feem ntau sib piv rau cov khoom siv hluav taws xob hauv tsev thiab txawv teb chaws & lub Hoobkas hluav taws xob xa khoom.
Ntau tus neeg yuav khoom tsuas xav tias ib hom zoo dua li lwm yam. Tab sis tom qab xa mus rau IEC cov qauv, cov kev qhia tshwj xeeb hauv lub tebchaws thiab ntau pua qhov haujlwm tiav, tsis yog AIS lossis GIS muaj qhov zoo. Txhawm rau ua qhov kev xaiv kom raug, koj yuav tsum ntsuas qhov chaw ntawm qhov chaw, ib puag ncig kev ua haujlwm, kev siv nyiaj txiag thiab qhov ntev - cov phiaj xwm nthuav dav. Kab lus no txheeb xyuas lawv qhov sib txawv tseem ceeb thiab qhia ncaj nraim, cov lus qhia xaiv cov tswv yim.
Lub hauv paus ntsiab lus ntawm AIS thiab GIS
AIS Air -Insulated Switchgear
AIS siv cov huab cua nyob ib puag ncig raws li kev rwb thaiv tsev sab hauv. Peb cov qauv tseem ceeb suav nrogKYN 28thiabXGN 15switchgears. Circuit Court breakers, busbars thiab tag nrho cov khoom nyob rau hauv lub txee, thiab kev nyab xeeb nyob rau hauv tiv thaiv siab -voltage txaus ntshai.
Nws qhov qhib layout cia cov neeg ua haujlwm pom txhua qhov sab hauv kom meej. Kev tu txhua hnub thiab ntxiv cov voj voog tshiab ntawm - qhov chaw tuaj yeem ua tiav yooj yim.
GIS Gas Insulated Switchgear
Peb tus qauv 12kV roj-insulated compact switchgear (C-GIS) poob hauv nruab nrab-voltage gas-insulated switchgear. Tag nrho cov khoom nyob tau raug kaw hauv airtight hlau chambers uas muaj SF₆ roj, uas ua haujlwm rwb thaiv tsev thiab arc extinction ua haujlwm.
Tag nrho cov khoom GIS ua tiav tag nrho cov kev sib khi thiab cov dej xau hauv peb lub hoobkas. Tsuas yog kev sib dhos yooj yim tsuas yog xav tau tom qab xa mus rau qhov chaw, thiab nws nyob hauv pem teb tsawg dua li AIS.

Pros, Cons & Applicable Scenarios rau Ob Hom Switchgear
AIS
AIS sawv tawm rau tus nqi pib qis thiab hloov pauv hloov pauv tom qab. Nws ua haujlwm zoo rau cov chaw ua haujlwm qhuav hauv av, cov chaw nyob deb nroog, thiab cov chaw tsim khoom lag luam uas npaj lub zog txuas ntxiv mus.
Txawm li cas los xij, nws muaj qhov pom tseeb tsis zoo. Nws xav tau chav faib hluav taws xob loj. Yog tias xa mus rau thaj chaw ntug dej hiav txwv lossis cov mines plua plav, cov insulators yuav sai sai cov av thiab hnub nyoog. Kev tu txhua xyoo yog qhov yuav tsum tau ua, uas nce mus ntev - cov nqi kho mob. Ntxiv dehumidifiers kuj tseem tsim nyog rau qhov chaw ntub dej.
GIS
Cov qauv kev cog lus thiab kev tiv thaiv zoo heev ua rau GIS yog qhov kev xaiv sab saum toj rau cov chaw ua haujlwm tsawg thiab hnyav, xws li cov chav hauv nroog hauv av, chaw nres tsheb photovoltaic ntawm ntug dej hiav txwv, kev tsheb ciav hlau thauj mus los thiab cov haujlwm hauv Middle East.
Nws cov qauv kaw tag nrho feem ntau txo qis tus nqi tsis ua haujlwm, ua kom ntev ntev -kev txij nkawm- ua haujlwm dawb. Cov qauv tsim qauv luv luv ntawm - lub sijhawm tsim kho qhov chaw thiab txuag nqi zog rau cov haujlwm txawv teb chaws.
Lub downside yog lub siab upfront peev. Yog tias koj xav tau ntxiv cov hluav taws xob tawm tshiab tom qab, cov kws tshaj lij yuav tsum tso cov pa tawm ntawm lub chamber, refill SF₆ thiab ua cov kev ntsuas siab dua. Tag nrho cov txheej txheem yog lub sij hawm -siv thiab complex. GIS suits tej yaam num nrog tas zog loads thiab tsis muaj loj reconstruction xav tau.
Yooj Yim Plaub- Daim Ntawv Qhia Kev Xaiv Qhov Loj
Koj tuaj yeem txiav txim siab lub txee tsim nyog los ntawm plaub yam tseem ceeb:
1. Chaw chaw xaiv AIS yog tias koj muaj chav fais fab loj lossis thaj chaw faib tawm sab nraud. Xaiv GIS rau compact underground los yog siab - nce hluav taws xob chav.
2. Kev ua haujlwm ib puag ncigAIS haum rau qhuav, qis- thaj tsam hauv av. GIS yog qhov kev xaiv tseem ceeb rau cov ntug dej hiav txwv ntsev pos huab thiab cov chaw mining plua plav.
3. Lub voj voog pabcuam & pob nyiaj Mus rau AIS luv luv - siv sijhawm (3–5 xyoos) nrog cov nyiaj tsawg. Yog tias koj qhov project khiav dhau 20 xyoo nrog cov av kim thiab cov nqi tsim kho vaj tse, GIS coj tau zoo dua - cov txiaj ntsig kev lag luam ntev.
4. Kev nthuav dav yav tom ntej xaiv AIS rau cov chaw tsim khoom thiab cov chaw ua haujlwm uas yuav khaws cov hluav taws xob txuas ntxiv. GIS phim cov haujlwm hauv nroog thiab kev lag luam nrog cov khoom ruaj khov thiab tsis muaj kev npaj kho dua tshiab.
Cov lus nug nquag
Q1: Qhov hloov pauv twg haum rau 11kV cov haujlwm hauv Middle East? GIS tau pom zoo rau ntug hiav txwv Dubai thiab Qatar vim muaj ntsev cua corrosion hnyav. Yog tias koj qhov project nyob hauv thaj chaw qhuav hauv av ntawm Saudi Arabia nrog qhov chaw txaus, AIS tuaj yeem tswj koj cov kev siv nyiaj yuav khoom.
Q2: Puas yog GIS muaj lub neej ua haujlwm ntev dua? Nyob rau hauv qhov chaw huv si thiab qhuav, lawv qhov kev pab cuam yuav luag zoo ib yam. Hauv cov ntsev hnyav thiab plua plav, cov qauv kaw GIS ua rau cov khoom qub, nrog rau kev pabcuam lub neej txog kaum xyoo ntev dua AIS.
Q3: Puas yog ob hom txee tuaj yeem xa tawm thoob ntiaj teb? AIS thiab GIS ua raws li IEC cov qauv kev lag luam. Tag nrho peb cov khoom dhau lub teb chaws tus qauv thiabDaim ntawv pov thawj CE, muaj feem xyuam rau cov phiaj xwm xa hluav taws xob hauv ntau lub teb chaws thoob ntiaj teb.
Cov lus kaw
Yooj yim hais, AIS yog tus nqi - zoo thiab kho tau rau feem ntau cov haujlwm. GIS yog me me - loj thiab ruaj khov, ua rau qhov chaw nqaim thiab ua haujlwm nyuaj. Tsis yog ib qho khoom lag luam tuaj yeem ua tiav txhua qhov kev xav tau engineering.
Yog tias koj tab tom tsim cov khoom siv hluav taws xob hauv tsev lossis txawv teb chaws & cov chaw ua haujlwm substation thiab tsis tuaj yeem lees paub tus qauv hloov pauv kom zoo, xa peb qhov project voltage, chav fais fab loj, huab cua hauv zos thiab cov phiaj xwm nthuav dav rau yav tom ntej. LVMA cov kws tshaj lij hluav taws xob engineers yuav tsim ib txoj kev npaj xaiv thiab cov lus hais raug raug rau koj.
Hais txog peb
Txij li thaum 2018, Zhejiang Lvma Electric Co., Ltd. ISO 9001: 2015 tau ntawv pov thawj, peb tsim cov tshuab hloov hluav taws xob ntse thiab cov roj hwm zoo- raus dej thiab qhuav- hom kev faib hluav taws xob rau cov neeg siv khoom hauv Europe, Middle East, South America, Southeast Asia, thiab Africa.
Nrog ntau tshaj 40 patents, peb lub peev xwm R & D tau hloov pauv cov kev tsim khoom ib txwm ua rau ntse, eco- cov tshuab hluav taws xob zoo. Kev ua haujlwm digital thiab kev saib xyuas kev ua neej nyob ua kom peb cov khoom ua tau raws li cov qauv kev nyab xeeb thiab kev ntseeg siab tshaj plaws.
