hore na ke hobane'ng ha VPD e le ea bohlokoa hakaale bakeng sa tlhahiso ea li-transformer tsa motlakase le hore na ke bo-mang bafepedi ba ka sehloohong Chaena

Ho omisa Mokhahlelo oa Mouoane (VPD) ke e 'ngoe ea lits'ebetso tsa bohlokoa ka ho fetisisa tlhahisong ea li-transformer tsa motlakase hobane e netefatsa hore mongobo o tlosoa ka botlalo tsamaisong ea ho futhumatsa (haholo-holo pampiri ea cellulose le boto ea khatiso). Mongobo ke e 'ngoe ea lira tse kholo tsa ts'epo ea li-transformer.

Ka tlase ke mabaka a bohlokoa a hore na ke hobane'ng ha VPD e le ea bohlokoa hakaale:

1. Mongobo o Fokotsa Matla a ho Thibela ho Kena Haholo

Mekhoa ea ho thibela ho tjheseletsa ea transformer e entsoe haholo-holo ka thepa ea cellulose (pampiri, boto ea khatiso) e kopantsoeng le oli ea transformer.

• Esita le mongobo oa 1-2% ka har'a cellulose o ka fokotsa matla a dielectric haholo.
• Metsi a ka baka ho ntšoa ha metsi ka karolo e itseng, ho hloleha ha ho kenya mocheso le liphoso tsa ka hare.

VPD e fokotsa mongobo o kenang mochesong hangata ho ba ka tlase ho 0.5%, e leng se hlokahalang bakeng sa di-transformer tse nang le motlakase o phahameng le tse nang le motlakase o mongata.

2. E Atolosa Bophelo ba Transformer

Mongobo o potlakisa botsofali ba cellulose ka hydrolysis.

Litlamorao tsa mongobo:

• Ho senyeha ha ketane ea polymer ka potlako
• Tekanyo e fokotsehileng ea polymerization (DP)
• Nako e khutšoanyane ea bophelo ba transformer

Ho omisa hantle ka VPD ho ka eketsa bophelo ba transformer ho tloha lilemong tse 20 ho isa ho tse 40+ maemong a mangata.

3. E Potlakile Haholo ho Feta ho Omisa ka Vacuum e Tloaelehileng

Ho omisa moea o chesang kapa vacuum ho tloaelehile hobane phetiso ea mocheso ka hare ho ho kobeha ha e sebetse hantle.

VPD e sebelisa solvent e nang le mouoane (hangata parafini) e leng:

• E kobeha holim'a sehatsetsi se batang
• E lokolla mocheso o moholo o patehileng
• E kenella ka botebo ka har'a lebili

Sephetho:

• Ho futhumatsa ka mokhoa o ts'oanang
• Ho omisa ka potlako haholo

Papiso e tloaelehileng ea nako:

Mokhoa oa ho omisa Nako e Tloaelehileng

Ho omisa moea o chesang matsatsi a 10--20

Ho omisa ka vacuum matsatsi a 5--10

VPD matsatsi a 2--5

4. Ho omisa ka botebo ha Meaho e Metenya ea ho Sireletsa

Li-transformer tse kholo tsa motlakase li na le meaho e teteaneng haholo ea ho thibela mocheso:

• Lisilindara tse teteaneng tsa boto ea khatiso
• Li-winding tse nang le mekhahlelo e mengata
• Likopano tse kholo tsa mantlha-khoele

VPD e fana ka ho futhumatsa ho tebileng, e leng se lumellang mongobo ho tsoa likarolong tse ka hare tsa ho thibela mocheso, e leng ntho e thata ka mekhoa e meng ea ho omisa.

5. Bohlokoa bakeng sa Li-Transformer tsa Voltage e Phahameng

Bakeng sa di-transformer tsa ≥220 kV, haholo-holo 400 kV / 500 kV / 765 kV, VPD e nkuwa e le disebediswa tse tloaelehileng tsa indasteri.

Bahlahisi ba bangata ba ka sehloohong ba e sebelisa, joalo ka:

• Siemens Energy
• Matla a Hitachi
• GE Vernova
• TBEA

Ntle le ho oma hantle, transformer e ke ke ea feta tšusumetso 'me AC e mamella liteko.

6. E ntlafatsa Bokgoni ba Tlhahiso

Mekhoa ea VPD e boetse e ntlafatsa katleho ea tlhahiso:

• Potoloho e kgutshwane ya tlhahiso
• Boleng bo tsitsitseng haholoanyane ba ho thibela ho ruruha
• Kotsi e tlase ea ho hloleha ha teko ea fektheri

Bakeng sa lifeme tse hlahisang li-transformer tse kholo tsa motlakase, VPD hangata e ba bothata ba tlhahiso, kahoo ts'epo ea eona le bokhoni ba eona li bohlokoa haholo.

Ka mantsoe a bonolo:

Haeba ho kobeha e le "pelo" ea transformer, ho oma ha insulation ke "bophelo" ba eona.

VPD ke tsela e sebetsang ka ho fetisisa ea ho netefatsa bophelo boo.

Kaha o boletse pejana hore o sebetsa ho ditheko tsa disebediswa tsa transformer bakeng sa merero ya Siemens, disebediswa tsa VPD hangata ke e nngwe ya dimetjhini tsa boleng bo hodimo le tse hlahlojwang ka botekgeniki haholo matseteng a feme ya transformer.

Haeba o rata, nka boela ka hlalosa:

• Hobaneng lifeme tse ngata tsa transformer li khetha VPD ho feta Hot Oil Spray (HOS)
• Litekanyetso tsa bohlokoa tsa tekheniki tseo bareki ba li hlahlobang ha ba etsa likopo tsa litsamaiso tsa VPD
• Ke lik'hamphani life tse busang 'maraka oa lisebelisoa tsa VPD lefatšeng ka bophara

Lintlha tsena hangata li bohlokoa haholo ho li-tender tsa lisebelisoa tsa transformer.

Indastering ea motlakase oa transformer, 'maraka oa lisebelisoa tsa Vapor Phase Drying (VPD) o monyane haholo ebile o ikhethile, ka palo e fokolang feela ea bafepedi ba nang le boiphihlelo lefatšeng ka bophara. Bahlahisi ba li-transformer hangata ba khetha bafepedi ba nang le litšupiso tse telele le theknoloji e pakiloeng ea ho omisa, hobane VPD e bohlokoa bakeng sa boleng ba ho kenya mocheso.

Ka tlase ke pono e sebetsang ea indasteri ea bafepedi ba ka sehloohong.

1. Bafepedi ba ka Sehloohong ba Lefatše ba Lisebelisoa tsa VPD

Likhamphani tsena ke bafepedi ba tsebahalang haholo lifekthering tse kholo tsa transformer lefatšeng ka bophara.

Baetapele ba Theknoloji ea Europe

• Micavac (Jeremane)
• E mong oa bahlahisi ba pele ba theknoloji ea VPD
• E tsebahala ka theknoloji ea JET e nang le patente ea evaporator
• Mehaho e mengata Europe le Asia
• Hangata e nkoa e le theknoloji e phahameng ka ho fetisisa
• Li-Piller Blower le Compressor (Jeremane)
• E fana ka litsamaiso tsa vacuum le litharollo tsa ho omisa bakeng sa limela tse kholo tsa transformer
• Hangata e kopantsoe le mela e meholo ea tlhahiso ea transformer.

2. Bafepedi ba ka Sehloohong ba Lisebelisoa tsa VPD tsa China

Chaena jwale e na le bafepedi ba mmalwa ba matla, haholoholo ba sebeletsang difeme tsa transformer tsa China le merero ya ho romela thepa kantle ho naha.

Bafepedi ba ka Sehloohong ba Machaena

Le Shanghai Trihope

• Mofani oa lifeme tsa transformer
• E fana ka litsamaiso tsa VPD, mela ea ho seha ea mantlha, mechini ea ho phunya foil, jj.
• Lisebelisoa li kentsoe lifekthering tse ngata lefatšeng ka bophara.

B Zhongshan Kaixuan Vacuum Technology

• E fana ka lifeme tsa VPD tse sebelisoang ke lik'hamphani tse kholo tsa transformer le lits'ebeletso tsa motlakase.

Bafepedi bana ba Chaena ba qothisana lehlokoa haholo ka theko mme ba sebediswa haholo ho:

• Asia Boroa-bochabela
• Bochabela bohareng
• amerika boroa
• Afrika

Mohlala, Shanghai Trihope e fane ka sete e le 'ngoe ea VPD ho PEL Pakistan, moetsi ea ka sehloohong oa transformer ea motlakase Asia Boroa. Lisebelisoa li ntse li sebetsa hantle 'me moreki o fane ka lengolo la teboho.
