Ukugcina Ukusebenza Okuhle Kwama-Wet Type Transformers: Amasu Okuxilonga

Ukugcina Ukusebenza Okuhle Kwama-Wet Type Transformers: Amasu Okuxilonga

Isingeniso

Ama-transformer ohlobo olumanzi ayizingxenye ezibalulekile ezinhlelweni zamandla kagesi, aguqula ugesi usuka kwelinye izinga le-voltage uye kwelinye. Ukuqinisekisa ukusebenza kwawo okuhle, amasu okuxilonga avamile abalulekile. Lesi sihloko sigxila ekubalulekeni kokuxilonga ama-transformer ohlobo olumanzi, sihlola amasu ahlukahlukene okuxilonga, futhi siqokomisa ukubaluleka kokugcinwa kwawo ekulondolozweni kokusebenza kwawo kanye nokusebenza kahle kwawo.

Ukuqonda Ama-Wet Type Transformers

Ama-transformer ohlobo olumanzi agqunywa ngezinto eziwuketshezi ze-dielectric, ngokuvamile uwoyela wamaminerali noma uketshezi olungashisi kakhulu. Lawa ma-transformer asetshenziswa kabanzi ngenxa yokusebenza kahle kwezindleko, ukuthembeka, kanye namakhono awo amahle kakhulu okushabalalisa ukushisa. Kodwa-ke, ngokuhamba kwesikhathi, izici zangaphakathi nezangaphandle zingathinta ukusebenza kwawo, okuholela ekwahlulekeni okungenzeka uma kungaxazululwa ngesikhathi.

Kungani Izindlela Zokuxilonga Zibalulekile

Amasu okuxilonga asebenza njengesinyathelo sokuvimbela ukuthola nokuhlonza noma yikuphi ukungahambi kahle kuma-transformer ohlobo olumanzi ngaphambi kokuba akhule abe yizinkinga ezinkulu. Ukuhlonza izinkinga kusenesikhathi kuvumela ukulungiswa okusheshayo, ukunciphisa isikhathi sokungasebenzi kanye nokunciphisa izindleko ezihambisanayo. Ukuhlonza njalo nakho kunegalelo ekwandiseni isikhathi sokuphila sama-transformer, kuthuthukisa ukusebenza kwawo kanye nokuthembeka.

I-Thermography Engaphansi Komoya Ecwiliswe Emanzini

I-Summerged Winding Thermography iyindlela yokuxilonga ethandwayo esetshenziswa ukuhlola isimo sangaphakathi sama-transformer ohlobo olumanzi. Ngokuthwebula izithombe zokushisa, izindawo ezishisayo ezingaba khona kanye nokuphambuka kokushisa kungatholakala. Amazinga okushisa aphezulu ezindaweni ezithile angabonisa iphutha, njengokuncipha kwesekethe esifushane noma ukwehla kokufakwa kokushisa. I-Summerged Winding Thermography ihlonza lezi zimo ezingavamile ngaphandle kwesidingo sezinqubo zokudiliza ezithatha isikhathi, zonga isikhathi kanye nomzamo.

Ukuhlaziywa Kwegesi Encibilikisiwe

Ukuhlaziywa Kwegesi Encibilikisiwe (i-DGA) kuyindlela ebalulekile ehlola amagesi ancibilikisiwe ku-oyela we-transformer. Njengoba amaphutha angaphakathi evelela ngaphakathi kwe-transformer, njengokushisa ngokweqile, ukugoba, noma ukukhishwa okuyingxenye, amagesi ahlukahlukene ayakhiqizwa futhi ancibilikisiwe ku-oyela. Ngokuhlaziya izinhlobo nobuningi bala magesi, amaphutha angaba khona angatholakala, kuhlinzekwe ukuqonda ngobucayi benkinga. Ukuchazwa okufanele kwemiphumela ye-DGA kwenza kube lula ukuhlonza izinkinga ezingaba khona futhi kusize ukungenelela ngesikhathi esifanele, kuvimbele ukuwohloka okubizayo.

Ukuqapha Ukukhishwa Okungaphelele

Ukuqapha Ukukhishwa Okungaphelele (PD) kungenye indlela ebalulekile yokuxilonga yama-transformer ohlobo olumanzi. I-PD yenzeka lapho ukukhishwa kukagesi okusendaweni ngaphakathi kwe-transformer insulation kuphumela ekukhiqizweni kwezimpawu zemvamisa ephezulu. Ukuqapha okuqhubekayo kwe-PD kusiza ekuhloleni isimo se-insulation ngesikhathi sangempela, okuvumela ukutholakala kusenesikhathi kwezinkinga ezikhulayo. Ngokusebenzisa amathuluzi okulinganisa imvamisa ephezulu kanye nama-algorithms athuthukile, imithombo ye-PD ingatholakala ngokunembile, okuholela ezenzweni zokulungisa nokulungisa eziqondiwe.

Ukuhlaziywa Komswakama Nokuqukethwe Kwamanzi

Ukuhlaziywa komswakama kanye nokuqukethwe kwamanzi kuma-transformer ohlobo olumanzi kubalulekile njengoba umswakama owedlulele ungaholela ekuwohlokeni kokufakwa kokushisa, kunciphise ukusebenza kwe-transformer. Ukugeleza komswakama kungenzeka ngenxa yezici ezahlukahlukene, njengezimbobo ezonakele noma ukuphefumula okungasebenzi kahle. Ukuhlaziywa njalo kokuqukethwe komswakama ku-oyili nezinto zokufakwa kokushisa kusiza ekuboneni izinkinga ezingaba khona, okuvumela izinyathelo zokuvimbela njengokomisa i-transformer noma ukulungisa ukufakwa kokushisa. Ngokunciphisa izinkinga ezihlobene nomswakama ngokushesha, ukusebenza kwe-transformer kungagcinwa, kuqinisekiswe ukuthi ihlala isikhathi eside.

Ukuhlaziywa Kwekhwalithi Kawoyela

Isimo samafutha okuvikela ukushisa kuma-transformer ohlobo olumanzi sidlala indima ebalulekile ekugcineni ukusebenza kahle. Ukuhlaziywa kwekhwalithi yamafutha okuvamile kusiza ukuhlola amandla e-dielectric kawoyela, izinga lokungcola, kanye nokuba khona kwanoma yiziphi izinto ezilimazayo noma izinhlayiya. Ngokubheka lezi zici, izinkinga ezingaba khona ezihlobene nokuqhekeka kwamafutha, ukonakala kokushisa, noma ukungcola okuyingozi kungabonakala kusenesikhathi. Ukufakwa esikhundleni noma ukuhlanzwa kwamafutha ngesikhathi kungavimbela ukulimala kwezingxenye ze-transformer futhi kulondolozwe ukusebenza kahle kwayo.

Isiphetho

Ukugcina ukusebenza kahle kwama-transformer ohlobo olumanzi kuyisici esibalulekile sokuphathwa kwesistimu yamandla kagesi. Amasu okuxilonga afana ne-Summerged Winding Thermography, i-Dissolved Gas Analysis, i-Partial Discharge Monitoring, i-Moisture and Water Content Analysis, kanye ne-Oil Quality Analysis kunegalelo ekutholakaleni kwamaphutha kusenesikhathi, kuqinisekisa ukungenelela okufika ngesikhathi nokuqondiwe. Ukuxilongwa njalo kanye nemisebenzi yokulungisa elandelayo kunciphisa ingozi yokwehluleka okukhulu, kunciphisa isikhathi sokungasebenzi, futhi kwandise isikhathi sokuphila sama-transformer ohlobo olumanzi. Ngokusebenzisa lawa masu ngenkuthalo, izimboni zingakhulisa ukusebenza kahle nokuthembeka kwezinhlelo zazo zamandla kagesi.
