TRANSFORMER

Cov ntsiab lus

220kV peb-theem roj immersed on-load voltage regulating transformer coj ib tug series ntawm loj transformations nyob rau hauv cov nqe lus ntawm cov khoom, txheej txheem, thiab kev tsim kho.Nws yog tus yam ntxwv ntawm kev tsim kho compact,
tsis muaj zog, ua haujlwm siab, poob qis, tsis muaj suab nrov, thiab kev ntseeg siab ntawm kev ua haujlwm.Cov khoom lag luam tuaj yeem txo qis kev poob qis ntawm daim phiaj thiab cov nqi ua haujlwm thiab txuas ntxiv cov txiaj ntsig kev lag luam.
Cov khoom ua tau raws li cov qauv hauv tebchaws: GB1094.1-2013 Fais fab transformers Part 1: General;GB1094.2-2013
Fais fab transformers Part 2: Kub nce;GB1094.3-2003 Fais fab transformers Part 3: Rwb thaiv tsev theem, dielectric xeem thiab lwm clearances nyob rau hauv huab cua;GB1094.5-2003 Fais fab transformers Part 5: Muaj peev xwm tiv taus luv luv;
GB / T6451-2015 Specification thiab technical specifications rau peb theem roj immerse fais fab transformers.

Nco ntsoov 1Transformers nrog ntsuas muaj peev xwm tsawg dua 31500 kVA thiab lwm yam kev sib txuas hluav taws xob kuj tuaj yeem muab tau raws li qhov xav tau.
Nco ntsoov 2 Transformers nrog tsawg voltage ntawm 35 kV lossis 38.5 kV kuj tuaj yeem muab tau raws li qhov xav tau.
Nco ntsoov 3 Cov qauv tsis sib cais yog nyiam.Yog tias muaj qee qhov kev xav tau rau kev ua haujlwm, sub-connectors tuaj yeem teeb tsa.
Nco ntsoov 4 Thaum qhov nruab nrab txhua xyoo load tus nqi ntawm transformer yog nyob nruab nrab ntawm 45% thiab 50%, qhov siab tshaj plaws kev khiav hauj lwm efficiency yuav tau los ntawm kev siv tus nqi poob nyob rau hauv lub rooj.

Lus Cim 1: Lub peev xwm faib khoom poob hauv lub rooj yog (100/100/100)%.Lub peev xwm faib ntawm boost qauv tuaj yeem ua tau
(100/50/100).Lub peev xwm faib ntawm Buck qauv tuaj yeem yog (100/50/100)% lossis (100/50/100)%.
Lus Cim 2: Transformers uas muaj peev xwm tsawg dua 31500 KA thiab lwm yam kev sib txuas hluav taws xob kuj tuaj yeem muab tau raws li qhov xav tau.
Lus Cim 3: Transformers uas tsis tshua muaj hluav taws xob ntawm 35 kV tuaj yeem muab tau raws li qhov xav tau.
Lus Cim 4: Qhov tseem ceeb yuav tsum tau muab rau cov qauv tsis sib cais.Yog tias qhov kev ua haujlwm xav tau, kev sib cais tuaj yeem teeb tsa.
Faj seeb 5: Thaum qhov nruab nrab txhua xyoo load tus nqi ntawm transformer yog nyob nruab nrab ntawm 45%, lub siab tshaj plaws kev khiav hauj lwm efficiency yuav tau los ntawm kev siv tus nqi poob nyob rau hauv lub rooj.

Nco tseg 1 Cov ntaub ntawv teev nyob rau hauv lub rooj yog siv rau depressurized structural khoom, thiab boost structural khoom kuj muab raws li qhov yuav tsum tau.
Nco ntsoov 2 Transformers nrog tsawg voltage ntawm 35 kV tuaj yeem muab tau raws li qhov xav tau.
Lus Cim 3 Thaum qhov nruab nrab txhua xyoo load tus nqi ntawm transformer yog nyob nruab nrab ntawm 45% thiab 50%, lub siab tshaj plaws kev khiav hauj lwm efficiency yuav tau los ntawm kev siv tus nqi poob nyob rau hauv lub rooj.

Nco tseg 1 Cov ntaub ntawv teev nyob rau hauv lub rooj yog siv rau depressurized structural khoom, thiab boost structural khoom kuj muab raws li qhov yuav tsum tau.
Nco ntsoov 2 Transformers uas tsis tshua muaj hluav taws xob ntawm 35 kV tuaj yeem muab tau raws li qhov xav tau.
Lus Cim 3 Thaum qhov nruab nrab txhua xyoo load tus nqi ntawm transformer yog nyob nruab nrab ntawm 45% thiab 50%, lub siab tshaj plaws kev khiav hauj lwm efficiency yuav tau los ntawm kev siv tus nqi poob nyob rau hauv lub rooj.

1.Cov khoom tshwj xeeb hauv cov npe khoom kuj tseem tuaj yeem muab raws li cov neeg siv khoom xav tau.Kev ua tau zoo ntawm cov khoom yuav raug kho.
2. Cov khoom siv hluav taws xob nruab nrab tuaj yeem xaiv tus nqi hluav taws xob lossis coj mus rhaub lwm yam tshaj li cov teev hauv lub rooj raws li tus neeg siv yuav tsum tau ua.High voltage tapping yuav xaiv asymmetrical regulating tapping.
3.Short circuit impedance tuaj yeem xaiv tus nqi uas tsis yog cov lus teev tseg.
4.Qhov kawg loj yog raws li cov duab kos ntawm daim ntawv cog lus.
