Vim li cas VPD thiaj li tseem ceeb rau kev tsim hluav taws xob transformer thiab leej twg yog cov neeg muag khoom loj hauv Suav teb

Kev ziab kom qhuav ntawm lub tshuab hluav taws xob (VPD) yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv kev tsim cov khoom siv hluav taws xob vim nws ua kom cov dej noo tawm ntawm lub tshuab rwb thaiv tsev (feem ntau yog cov ntawv cellulose thiab cov ntawv xovxwm). Cov dej noo yog ib qho ntawm cov yeeb ncuab loj tshaj plaws ntawm kev ntseeg tau ntawm lub tshuab hluav taws xob.

Hauv qab no yog cov laj thawj tseem ceeb uas ua rau VPD tseem ceeb heev:

1. Cov dej noo ua rau lub zog rwb thaiv tsev tsawg zuj zus

Cov txheej txheem rwb thaiv tsev transformer feem ntau yog tsim los ntawm cov ntaub ntawv cellulose (ntawv, ntawv xovxwm) ua ke nrog roj transformer.

• Txawm tias 1-2% dej noo hauv cellulose tuaj yeem txo qhov dielectric zog.
• Dej tuaj yeem ua rau muaj kev tso tawm ib feem, kev ua tsis tiav ntawm kev rwb thaiv tsev, thiab kev ua haujlwm sab hauv.

VPD txo cov dej noo hauv cov rwb thaiv tsev feem ntau kom qis dua 0.5%, uas yog qhov xav tau rau cov transformers high-voltage thiab extra-high-voltage.

2. Ntev lub neej ntawm Transformer

Cov dej noo ua rau cellulose laus sai dua los ntawm kev hydrolysis.

Cov teebmeem ntawm cov dej noo:

• Kev puas tsuaj ntawm cov saw polymer sai dua
• Txo qib ntawm polymerization (DP)
• Lub neej transformer luv dua

Kev ziab kom zoo los ntawm VPD tuaj yeem ua rau lub neej ntawm lub transformer ntev dua los ntawm 20 xyoo mus rau 40+ xyoo hauv ntau kis.

3. Sai dua li Kev Siv Lub Tshuab Nqus Tsev Qhuav

Cov cua kub ib txwm muaj los yog lub tshuab nqus tsev ziab qeeb vim tias kev hloov pauv cua sov hauv lub winding tsis zoo.

VPD siv cov tshuaj ua kom vaporized (feem ntau yog kerosene) uas:

• Nqus dej rau ntawm qhov chaw txias rwb thaiv tsev
• Tso tawm cov cua sov loj loj
• Nkag mus tob rau hauv qhov winding

Qhov Tshwm Sim:

• Kev ua kom sov sib xws
• Qhuav sai dua

Kev sib piv lub sijhawm ib txwm muaj:

Txoj Kev Qhuav Lub Sijhawm Ib Txwm

Cua kub ziab 10--20 hnub

Tshuab nqus tsev kom qhuav 5--10 hnub

VPD 2--5 hnub

4. Kev Qhuav Sib Sib Zog ntawm Cov Qauv Rwb Thaiv Kub Tuab

Cov transformers loj muaj cov qauv rwb thaiv tsev tuab heev:

• Cov thooj voos kheej kheej tuab
• Cov xov hlau ntau txheej
• Cov khoom sib dhos loj loj

VPD muab cua sov nkag mus tob, tso cai rau cov dej noo tawm ntawm cov txheej rwb thaiv tsev sab hauv, uas nyuaj rau lwm txoj kev ziab.

5. Qhov tseem ceeb rau High Voltage Transformers

Rau cov transformers ≥220 kV, thiab tshwj xeeb tshaj yog 400 kV / 500 kV / 765 kV, VPD raug suav hais tias yog cov khoom siv txheem kev lag luam.

Feem ntau cov chaw tsim khoom loj siv nws, xws li:

• Siemens Zog
• Hitachi Zog
• GE Vernova
• TBEA

Yog tsis muaj kev ziab kom zoo, lub transformer yuav tsis dhau qhov kev sim impulse thiab AC withstand.

6. Txhim kho Kev Ua Haujlwm Zoo

Cov txheej txheem VPD kuj tseem txhim kho kev ua haujlwm ntawm kev tsim khoom:

• Lub voj voog tsim khoom luv dua
• Kev rwb thaiv tsev zoo dua qub
• Kev pheej hmoo tsawg dua ntawm kev ua tsis tiav ntawm kev sim hauv Hoobkas

Rau cov chaw tsim cov tshuab hluav taws xob loj, VPD feem ntau dhau los ua qhov tsis zoo ntawm kev tsim khoom, yog li nws qhov kev ntseeg tau thiab lub peev xwm tseem ceeb heev.

Hauv cov lus yooj yim:

Yog tias winding yog "lub plawv" ntawm lub transformer, qhov qhuav ntawm rwb thaiv tsev yog nws "lub neej".

VPD yog txoj hauv kev zoo tshaj plaws los lav lub neej ntawd.

Vim koj tau hais ua ntej lawm tias koj tab tom ua haujlwm rau cov khoom siv transformer rau Siemens cov haujlwm, cov khoom siv VPD feem ntau yog ib qho ntawm cov tshuab muaj nqis tshaj plaws thiab ntsuas tau zoo tshaj plaws hauv kev nqis peev hauv lub Hoobkas transformer.

Yog koj xav tau, kuv kuj piav qhia tau:

• Vim li cas ntau lub Hoobkas transformer nyiam VPD dua li Cov Roj Kub Tsuag (HOS)
• Cov kev ntsuas tseem ceeb uas cov neeg siv khoom ntsuas thaum twv VPD systems
• Cov tuam txhab twg tswj hwm kev lag luam khoom siv VPD thoob ntiaj teb

Cov ntsiab lus no feem ntau tseem ceeb heev hauv kev sib tw khoom siv transformer.

Hauv kev lag luam fais fab transformer, kev lag luam khoom siv Vapor Phase Drying (VPD) yog qhov me me thiab tshwj xeeb, tsuas muaj tsawg tus neeg muag khoom uas muaj kev paub thoob ntiaj teb xwb. Cov chaw tsim khoom siv transformer feem ntau xaiv cov neeg muag khoom uas muaj cov ntaub ntawv ntev thiab cov thev naus laus zis ziab uas tau lees paub, vim tias VPD yog qhov tseem ceeb rau qhov zoo ntawm kev rwb thaiv tsev.

Hauv qab no yog kev pom tseeb ntawm kev lag luam ntawm cov neeg muab khoom loj.
