Ii-Wet type transformers zizinto ezibalulekileyo kwiinkqubo zamandla ombane, ziguqula umbane ukusuka kwinqanaba elinye le-voltage ukuya kwelinye. Ukuqinisekisa ukusebenza kwazo kakuhle, iindlela zokuxilonga rhoqo zibalulekile. Eli nqaku ligxila ekubalulekeni kokuxilonga ii-wet type transformers, liphonononga iindlela ezahlukeneyo zokuxilonga, kwaye ligxininisa ukubaluleka kokugcinwa kolondolozo ekusebenzeni kwazo kunye nokusebenza kwazo kakuhle.

Ukuqonda ii-Wet Type Transformers

Ii-transformer ezimanzi zigqunywe ngezinto ezisebenzisa ulwelo lwe-dielectric, ngesiqhelo ioyile yeminerali okanye ulwelo olungatshiyo kakhulu. Ezi transformer zisetyenziswa kakhulu ngenxa yokuba zisebenza kakuhle ngexabiso, ukuthembeka, kunye nokukwazi kwazo ukusasaza ubushushu ngendlela egqwesileyo. Nangona kunjalo, ngokuhamba kwexesha, izinto zangaphakathi nezangaphandle zinokuchaphazela ukusebenza kwazo, nto leyo ekhokelela kwiingxaki ezinokwenzeka ukuba azilungiswanga ngexesha elifanelekileyo.

Kutheni Iindlela Zokuxilonga Zibalulekile

Iindlela zokuxilonga zisebenza njengendlela yokuthintela ukufumanisa nokuchonga naziphi na izinto ezingaqhelekanga kwii-transformers zohlobo olumanzi ngaphambi kokuba zikhule zibe yingxaki ebalulekileyo. Ukuchongwa kwangethuba kweengxaki kuvumela ukulungiswa ngokukhawuleza, ukunciphisa ixesha lokungasebenzi kunye nokunciphisa iindleko ezinxulumene noko. Ukuxilongwa rhoqo kukwanegalelo ekwandiseni ubomi be-transformers, kuphucula ukusebenza kwazo ngokubanzi kunye nokuthembeka.

I-Thermography Ejijekileyo Engaphantsi Kwehlabathi

I-Summerged Winding Thermography yindlela edumileyo yokuxilonga esetyenziselwa ukuvavanya imeko yangaphakathi yee-transformers zohlobo olumanzi. Ngokuthatha imifanekiso yobushushu, iindawo ezishushu ezinokubakho kunye nokuphambuka kobushushu kunokubonwa. Amaqondo obushushu aphezulu kwiindawo ezithile anokubonisa isiphene, esifana ne-short circuit okanye i-winding insulation degradation. I-Summerged Winding Thermography ichonga ezi anomalies ngaphandle kwesidingo seenkqubo zokudiliza ezithatha ixesha, oko konga ixesha kunye nomgudu.

Uhlalutyo lweGesi enyibilikisiweyo

Uhlalutyo lweGesi eDissolved (DGA) yindlela ebalulekileyo ehlola iigesi ezinyibilikisiweyo kwioyile yetransformer. Njengoko iimpazamo zangaphakathi zenzeka ngaphakathi kwitransformer, ezinje ngokushisa kakhulu, ukurhangqa, okanye ukukhupha okungaphelelanga, iigesi ezahlukeneyo ziyaveliswa kwaye zinyibilikiswe kwioyile. Ngokuhlalutya iintlobo kunye nobungakanani bezi gesi, iimpazamo ezinokubakho zinokufunyanwa, zibonelele ngobunzulu bengxaki. Ukutolikwa ngokuchanekileyo kweziphumo zeDGA kwenza ukuba kuchongwe iingxaki ezinokubakho kwaye kuququzelele ukungenelela ngexesha elifanelekileyo, kuthintelwe ukonakala okubiza kakhulu.

Ukubeka iliso ekukhutshweni kwenkunkuma ngokungaphelelanga

Ukubeka iliso kwi-Partial Discharge (PD) yenye indlela ebalulekileyo yokuxilonga ii-transformers zohlobo olumanzi. I-PD yenzeka xa ukukhutshwa kombane kwindawo ethile ngaphakathi kwi-transformer insulation kuphumela ekuvelisweni kwemiqondiso ye-high-frequency. Ukubeka iliso kwi-PD rhoqo kunceda ekuvavanyeni imeko ye-insulation ngexesha langempela, okuvumela ukubonwa kwangoko kweengxaki ezikhulayo. Ngokusebenzisa izixhobo zokulinganisa ze-high-frequency kunye nee-algorithms eziphambili, imithombo ye-PD inokufumaneka ngokuchanekileyo, nto leyo ekhokelela kwizenzo zokulungisa nokulungisa ezijoliswe kuzo.

Uhlalutyo loMxholo woBumanzi kunye noManzi

Uhlalutyo lomswakama kunye nomthamo wamanzi kwiitransformer ezimanzi lubalulekile njengoko ukufuma okugqithisileyo kunokukhokelela ekonakaleni kobushushu, kunciphisa ukusebenza kwetransformer. Ukugcwala komswakama kunokwenzeka ngenxa yezizathu ezahlukeneyo, ezinje ngeegaskets ezonakeleyo okanye ii-breathing ezingasebenzi kakuhle. Uhlalutyo oluqhelekileyo lomthamo womswakama kwioyile kunye nezixhobo zobushushu lunceda ekuchongeni iingxaki ezinokubakho, okuvumela amanyathelo okuthintela njengokomisa itransformer okanye ukulungisa ubushushu. Ngokunciphisa iingxaki ezinxulumene nomswakama ngokukhawuleza, ukusebenza kwetransformer kunokugcinwa, kuqinisekisa ukuba ihlala ixesha elide.

Uhlalutyo loMgangatho weOyile

Imeko yeoyile yokukhusela kwiitransformer ezimanzi idlala indima ebalulekileyo ekugcineni ukusebenza kakuhle. Uhlalutyo lomgangatho weoyile oluqhelekileyo lunceda ukuvavanya amandla e-dielectric eoyile, ubungakanani bokungcola, kunye nokuba khona kwazo naziphi na izinto ezibangela ukubola okanye amasuntswana. Ngokujonga ezi zinto, iingxaki ezinokubakho ezinxulumene nokuqhekeka kweoyile, ukonakala kobushushu, okanye ukungcola okuyingozi zinokuchongwa kwangethuba. Ukutshintshwa okanye ukucocwa kweoyile ngexesha elifanelekileyo kunokuthintela umonakalo kwiinxalenye zetransformer kwaye kugcinwe ukusebenza kwayo kakuhle.

Isiphelo

Ukugcina ukusebenza kakuhle kwee-wet type transformers yinto ebalulekileyo ekulawulweni kwenkqubo yamandla ombane. Iindlela zokuxilonga ezifana ne-Summerged Winding Thermography, i-Dissolved Gas Analysis, i-Partial Discharge monitoring, i-Moisture and Water Content Analysis, kunye ne-Oil Quality Analysis zinegalelo ekufumaneni iimpazamo kwangethuba, ukuqinisekisa ukungenelela ngexesha elifanelekileyo nangokujoliswe kuko. Ukuxilongwa rhoqo kunye nemisebenzi yokulungisa elandelayo kunciphisa umngcipheko wokungaphumeleli okukhulu, kunciphisa ixesha lokungasebenzi, kwaye kwandise ubomi bee-wet type transformers. Ngokusebenzisa ezi ndlela ngenkuthalo, amashishini anokwandisa ukusebenza kakuhle kunye nokuthembeka kweenkqubo zawo zamandla ombane.
