kungani i-VPD ibaluleke kangaka ekukhiqizweni kwe-power transformer nokuthi obani abahlinzeki abakhulu eShayina

Ukomisa i-Vapor Phase (VPD) kungenye yezinqubo ezibaluleke kakhulu ekukhiqizweni kwe-power transformer ngoba kuqinisekisa ukususwa okuphelele komswakama ohlelweni lokuvikela (ikakhulukazi iphepha le-cellulose kanye nebhodi lokucindezela). Umswakama ungenye yezitha ezinkulu zokuthembeka kwe-transformer.

Nazi izizathu ezibalulekile zokuthi kungani i-VPD ibaluleke kangaka:

1. Umswakama Unciphisa Kakhulu Amandla Okuvimbela Ukushisa

Izinhlelo zokushisa ze-transformer zakhiwe kakhulu ngezinto ze-cellulose (iphepha, ibhodi lokunyathelisa) ezihlanganiswe namafutha e-transformer.

• Ngisho nomswakama ongu-1-2% ku-cellulose unganciphisa kakhulu amandla e-dielectric.
• Amanzi angabangela ukukhishwa kwengxenye, ukwehluleka kokufakwa kokushisa, kanye namaphutha angaphakathi.

I-VPD yehlisa okuqukethwe komswakama ekushiseni ngokuvamile kube ngaphansi kuka-0.5%, okudingekayo kuma-transformer ane-voltage ephezulu kanye ne-extra-high-voltage.

2. Yandisa Isikhathi Sokuphila Sokuguqulwa

Umswakama usheshisa ukuguga kwe-cellulose nge-hydrolysis.

Imiphumela yomswakama:

• Ukuwohloka kweketanga le-polymer okusheshayo
• Izinga elincishisiwe le-polymerization (DP)
• Isikhathi sokuphila esifushane se-transformer

Ukomisa kahle nge-VPD kungandisa impilo ye-transformer kusukela eminyakeni engama-20 kuya eminyakeni engama-40+ ezimweni eziningi.

3. Kushesha Kakhulu Kunokomisa Nge-Vacuum Okuvamile

Umoya oshisayo wendabuko noma ukomisa nge-vacuum kuhamba kancane ngoba ukudluliselwa kokushisa ngaphakathi kokugoqa akusebenzanga kahle.

I-VPD isebenzisa i-solvent ephefumulayo (ngokuvamile i-parafini) oku:

• Iyancipha ebusweni bokufudumeza obubandayo
• Ikhipha ukushisa okukhulu okucashile
• Ingena ijule ekugoqeni

Umphumela:

• Ukushisa okufanayo
• Ukomisa okusheshayo kakhulu

Ukuqhathaniswa kwesikhathi okuvamile:

Indlela Yokomisa Isikhathi Esijwayelekile

Ukomisa umoya oshisayo izinsuku eziyi-10--20

Ukomisa nge-vacuum izinsuku ezi-5--10

I-VPD izinsuku ezingu-2--5

4. Ukomisa Okujulile Kwezakhiwo Zokufaka Ukushisa Okujiyile

Ama-transformer amakhulu anezakhiwo zokushisa ezijiyile kakhulu:

• Amasilinda ebhodi lokunyathelisa aminyene
• Amawindidi anezingqimba eziningi
• Izinhlangano ezinkulu ze-core-coil

I-VPD inikeza ukushisa okujulile, okuvumela umswakama ukuthi uphume ezingqimbeni zokuvikela zangaphakathi, okunzima ngezinye izindlela zokomisa.

5. Kubalulekile kuma-Transformers e-High Voltage

Kuma-transformer angu-≥220 kV, ikakhulukazi angu-400 kV / 500 kV / 765 kV, i-VPD ibhekwa njengemishini ejwayelekile embonini.

Abakhiqizi abaningi abakhulu bayayisebenzisa, njenge:

• Amandla e-Siemens
• I-Hitachi Energy
• GE Vernova
• I-TBEA

Ngaphandle kokomiswa kahle, i-transformer ayikwazi ukudlula ekushukumeni futhi i-AC imelane nokuhlolwa.

6. Kuthuthukisa Ukusebenza Kahle Kokukhiqiza

Izinhlelo ze-VPD zithuthukisa nokusebenza kahle kokukhiqiza:

• Umjikelezo wokukhiqiza omfushane
• Ikhwalithi yokuvikela ehambisanayo
• Ingozi ephansi yokwehluleka kokuhlolwa kwefektri

Emafektri akhiqiza ama-transformer amakhulu kagesi, i-VPD ivame ukuba yisithiyo sokukhiqiza, ngakho-ke ukuthembeka kwayo kanye nomthamo wayo kubalulekile.

Ngamagama alula:

Uma ukugoqa “kuyinhliziyo” ye-transformer, ukoma kokushisa “kuyimpilo” yayo.

I-VPD iyindlela ephumelela kakhulu yokuqinisekisa lokho kuphila.

Njengoba ushilo ngaphambilini ukuthi usebenza kumathenda emishini ye-transformer yamaphrojekthi e-Siemens, imishini ye-VPD ivame ukuba ngomunye wemishini enenani eliphezulu kakhulu futhi ehlolwa kakhulu ngobuchwepheshe ekutshalweni kwezimali kwefektri ye-transformer.

Uma ungathanda, ngingachaza futhi:

• Kungani izimboni eziningi ze-transformer zikhetha i-VPD kune-Hot Oil Spray (HOS)
• Amapharamitha abalulekile obuchwepheshe amakhasimende ahlola lapho ebhida izinhlelo ze-VPD
• Yiziphi izinkampani ezilawula imakethe yemishini ye-VPD emhlabeni jikelele

La maphuzu avame ukuba abaluleke kakhulu kumathenda emishini ye-transformer.

Embonini yokuguqula amandla, imakethe yemishini ye-Vapor Phase Drying (VPD) incane kakhulu futhi ikhethekile, ngenani elilinganiselwe labahlinzeki abanolwazi emhlabeni jikelele. Abakhiqizi be-transformer bavame ukukhetha abahlinzeki abanezinkomba ezinde kanye nobuchwepheshe bokomisa obuqinisekisiwe, ngoba i-VPD ibalulekile kwikhwalithi yokushisa.

Ngezansi umbono osebenzayo wemboni ngabaphakeli abakhulu.

1. Abaphakeli Abakhulu Bomhlaba Wonke Bemishini ye-VPD
