impamvu VPD ari ingenzi cyane mu gukora transformateur z'amashanyarazi kandi ni bande batanga serivisi zikomeye mu Bushinwa

Kumisha umwuka mu buryo bwa Vapor Phase (VPD) ni imwe mu nzira z'ingenzi cyane mu gukora transformer zikoresha ingufu kuko zituma amazi akurwa burundu mu buryo bwo gushyushya (cyane cyane impapuro za cellulose n'ikibaho cyo gukanda). Ubushuhe ni kimwe mu byanga bikomeye transformer ikora neza.

Dore impamvu z'ingenzi zituma VPD ari ingenzi cyane:

1. Ubushuhe bugabanya cyane imbaraga zo gukingira

Sisitemu zo gukingira transformer zigizwe ahanini n'ibikoresho bya selulose (impapuro, ikibaho cyo gukanda) bivanze n'amavuta ya transformer.

• Ndetse n'ubushuhe buri hagati ya 1–2% muri selulose bushobora kugabanya cyane imbaraga za dielectric.
• Amazi ashobora gutera gusohora igice cy'amazi, kwangirika k'ubushyuhe, ndetse n'ikosa ry'imbere mu mubiri.

VPD igabanya ubushuhe mu byuma bikingira ubushyuhe kugeza munsi ya 0.5%, ibi bikaba bikenewe ku byuma bihindura amashanyarazi bifite ingufu nyinshi n'amashanyarazi menshi cyane.

2. Yongera igihe cy'ubuzima bwa Transformer

Ubushuhe bwihutisha gusaza kwa selulose binyuze mu guhidilisha.

Ingaruka z'ubushuhe:

• Kwangirika kw'uruhererekane rwa polymeri vuba
• Kugabanuka k'urwego rwa polimeri (DP)
• Igihe cy'ubuzima bugufi bwa transformer

Kumisha neza hakoreshejwe VPD bishobora kongera ubuzima bwa transformer kuva ku myaka 20 kugeza ku myaka 40+ mu bihe byinshi.

3. Yihuta cyane kurusha imashini isanzwe yo kumisha imashini

Umuyaga ushyushye cyangwa icyuma gishyushya gisanzwe bitinda kuko uburyo bwo kohereza ubushyuhe mu gikoresho cyo kuzunguruka budakora neza.

VPD ikoresha umuti uva mu mwuka (ubusanzwe peteroli) utuma:

• Ifunze ku buso bukonje bw'ubushyuhe
• Irekura ubushyuhe bwinshi buhishe
• Yinjira cyane mu muyaga uzunguruka

Ibisubizo:

• Gushyushya bingana
• Kumisha vuba cyane

Igereranya ry'igihe risanzwe:

Uburyo bwo Kumisha Igihe gisanzwe

Kumisha umwuka ushyushye iminsi 10--20

Kumisha imashini mu cyuma mu minsi 5--10

VPD iminsi 2--5

4. Kumisha cyane ibikoresho binini byo gukingira

Transformateur nini zifite imiterere ikomeye cyane yo gukingira:

• Silinda nini zo gukanda
• Ingufu zo kuzunguruka zifite ibyiciro byinshi
• Amateraniro manini y'inkingi z'imbere

VPD itanga ubushyuhe bwimbitse, bigatuma ubushuhe busohoka buva mu bice by'imbere by'ubushyuhe, ibyo bikaba bigoye mu bundi buryo bwo kumisha.

5. Ni ngombwa ku bahindura amashanyarazi bafite ingufu nyinshi

Ku byuma bihindura amashanyarazi ≥220 kV, cyane cyane 400 kV / 500 kV / 765 kV, VPD ifatwa nk'ibikoresho bisanzwe mu nganda.

Inganda nyinshi zikomeye zirayikoresha, nka:

• Siemens Energy
• Hitachi Energy
• GE Vernova
• TBEA

Iyo transformateur idafunguye neza, ntishobora kwihanganira ibizamini bya AC.

6. Binoza imikorere myiza y'umusaruro

Sisitemu za VPD nazo zinoza imikorere myiza mu nganda:

• Igihe gito cyo gukora
• Ubwiza buhamye bwo gukingira
• Ingaruka nke zo gutsindwa kw'igeragezwa ry'uruganda

Ku nganda zikora transformateur nini zitanga ingufu, VPD ikunze kuba inzitizi ku musaruro, bityo icyizere n'ubushobozi byayo ni ingenzi cyane.

Mu magambo yoroshye:

Niba kuzunguruka ari "umutima" wa transformateur, kumisha insulation ni "ubuzima" bwayo.

VPD ni bwo buryo bwiza bwo kwemeza ko ubuzima buzaba bwiza.

Kubera ko wavuze mbere ko urimo gukora ku masoko yo gutanga ibikoresho bya transformer ku mishinga ya Siemens, ibikoresho bya VPD akenshi ni imwe mu mashini zifite agaciro kanini kandi zisuzumwa cyane mu ishoramari ry’inganda za transformer.

Niba ubyifuza, nshobora no kubisobanura:

• Impamvu inganda nyinshi zikoresha transformer zikunda VPD kuruta Hot Oil Spray (HOS)
• Ibipimo by'ingenzi bya tekiniki abakiriya basuzuma iyo batanze amasoko kuri sisitemu ya VPD
• Ni izihe kompanyi ziganje ku isoko ry'ibikoresho bya VPD ku isi

Izi ngingo akenshi ziba ingenzi cyane mu gutanga amasoko ku bikoresho bya transformer.

Mu nganda zikora transformateur z'amashanyarazi, isoko ry'ibikoresho bya Vapor Phase Kumisha (VPD) ni rito kandi ryihariye, ifite umubare muto w’abatanga ibikoresho by’uburambe ku isi. Abakora transformer bakunze guhitamo abatanga ibikoresho bafite ikoranabuhanga rigezweho ryo kumisha, kuko VPD ari ingenzi cyane mu kugira ubuziranenge bwo gukingira.

Hasi aha hari ishusho ifatika y'abatanga ibicuruzwa bakomeye.

1. Abatanga ibikoresho bya VPD ku rwego rw'isi

Izi kompanyi zizwi cyane mu gutanga ibikoresho binini bya transformer ku isi.

Abayobozi b'ikoranabuhanga mu Burayi

• Micavac (Ubudage)
• Umwe mu ba mbere mu bateje imbere ikoranabuhanga rya VPD
• Bizwiho ikoranabuhanga rya JET evaporator rifite patenti
• Ahantu henshi hakorerwa imirimo mu Burayi no muri Aziya
• Akenshi bifatwa nk'ikoranabuhanga ryo ku rwego rwo hejuru
• Imashini zikoresha amashanyarazi n'ibikoresho byo gukamura (Ubudage)
• Itanga uburyo bwo gusukura no kumisha ibyuma binini bya transformer
• Akenshi bihuzwa n'imirongo minini ikora transformer.

2. Abatanga ibikoresho bikomeye by'Abashinwa bya VPD

Ubu Ubushinwa bufite abatanga serivisi benshi bakomeye, ahanini bakorera inganda z’Abashinwa zihindura amashanyarazi ndetse n’imishinga yo kohereza ibicuruzwa mu mahanga.

Abatanga ibicuruzwa b'Abashinwa Bakomeye

Na Shanghai Trihope

• Umucuruzi w'inganda zihindura amashanyarazi (transformers)
• Itanga sisitemu za VPD, imirongo yo gukata inkingi, imashini zizunguza amabati, nibindi.
• Ibikoresho byashyizwe mu nganda nyinshi ku isi.

B Zhongshan Kaixuan Ikoranabuhanga rya Vacuum

• Itanga inganda za VPD zikoreshwa n'ibigo binini bya transformer n'ibigo by'ubucuruzi.

Aba bacuruzi b'Abashinwa barapiganwa cyane ku giciro kandi bakunze gukoreshwa muri ibi bikurikira:

• Aziya y'Amajyepfo y'Uburasirazuba
• Uburasirazuba bwo Hagati
• Amerika y'Epfo
• Afurika

Urugero, Shanghai Trihope yahaye PEL Pakisitani, ikigo gikomeye mu ruganda rukora transformateur z'amashanyarazi muri Aziya y'Amajyepfo seti imwe ya VPD. Ibikoresho byagiye bikora neza kandi umukiriya yatanze ibaruwa yo gushimira.
