Indima Ebalulekile Yokushisa Okugoqekayo Ekunakekelweni Kwe-Transformer

Indima Ebalulekile Yokushisa Okugoqekayo Ekunakekelweni Kwe-Transformer

Isingeniso:

Ama-transformer adlala indima ebalulekile ekusebenzeni kahle kwezinhlelo zamandla kagesi. Ukuthembeka kwawo kanye nokusebenza kahle kuncike ezintweni eziningi, esinye sazo izinga lokushisa lama-windings awo. Izinga lokushisa lama-windings lithinta ngqo ukusebenza kanye nesikhathi sokuphila kwama-transformer, okwenza kube yisici esibalulekile sokugcinwa kwawo. Lesi sihloko sigxila ekubalulekeni kwezinga lokushisa lama-windings ekunakekelweni kwama-transformer futhi sihlola amasu ahlukahlukene ukuqinisekisa izimo zokusebenza ezifanele.

Ukuqonda Izinga Lokushisa Eligobile:

1. Amasu Okulinganisa

Ukulinganisa okunembile kwezinga lokushisa eligoqekayo kubaluleke kakhulu ekugcinweni okuphumelelayo. Kusetshenziswa amasu amaningana ukuqapha le pharamitha ebalulekile. Enye indlela evamile ihilela ukusetshenziswa kwezitholi zokushisa ezimelana nokumelana (ama-RTD) ezifakwe ngaphakathi kwama-windings. Ama-RTD ahlinzeka ngezilinganiso ezinembile njengoba eguqula ukushintsha kwezinga lokushisa kube izinguquko ezihambisanayo zokumelana nogesi. Enye indlela ihilela i-infrared thermography, lapho kusetshenziswa khona amakhamera okuthatha izithombe ezishisayo angathintani ukuhlola ukusatshalaliswa kwezinga lokushisa eligoqekayo.

2. Ukulingana Kokushisa

Ukugcina ukulingana kokushisa kubalulekile ukuvimbela ukwenyuka okukhulu kokushisa, okungaholela ekuwohlokeni kokushisa kanye nokuncipha kwesikhathi sokuphila kwe-transformer. Ama-transformer athembele ezindleleni ezifanele zokupholisa, njengokushintshashintsha kwemvelo noma ukupholisa komoya/amanzi okuphoqelelwe, ukuze kususwe ukushisa okukhiqizwa ngesikhathi sokusebenza. Ukuhlolwa njalo kanye nokuhlaziywa kokushintshashintsha kokushisa okuguqukayo kusiza ekuboneni noma yikuphi ukuphambuka ekulinganeni kokushisa, okuvumela ukungenelela kokulungisa okusheshayo.

Umthelela Wokushisa Okugoqekayo Empilweni Ye-Transformer:

1. Ukuguga Kokuvikela Ukushisa

Ukushisa okujiyile okujiyile kusheshisa inqubo yokuguga kwe-transformer insulation. Izinto zokufaka insulation, ezivame ukwakhiwa ngephepha, ibhodi lokunyathelisa, noma ama-polymer, zenza izinguquko zomzimba nezamakhemikhali lapho zibhekene nokushisa okuphezulu. Ngokuhamba kwesikhathi, lokhu kungabangela ukuwohloka kwe-insulation, ukwehla kwamandla e-dielectric, kanye nokwanda kobuthakathaka bamaphutha kagesi.

2. Ukulahlekelwa Nokusebenza Kahle

Ukusebenza kahle kwama-transformer kuthonywa kakhulu izinga lokushisa eligoqekayo. Njengoba izinga lokushisa likhuphuka, kanjalo nokulahlekelwa yithusi kanye ne-core. Ukulahlekelwa yithusi kwenzeka kuma-winding conductors ngenxa yokushisa okumelana nokushisa, kuyilapho ukulahlekelwa yi-core kubangelwa yi-magnetization hysteresis kanye ne-eddy currents. Ukwanda kokulahlekelwa kunciphisa ukusebenza kahle kwamandla futhi kukhiqiza nokushisa okwengeziwe, okudala umjikelezo oziqinisayo okhulisa izinga lokushisa eligoqekayo.

Amasu Okulungisa:

1. Ukuqapha Izinga Lokushisa Okuvamile

Ukuqapha izinga lokushisa okuqhubekayo kubalulekile ekutholeni ukushintshashintsha kwezinga lokushisa okungavamile. Ukulinganisa okuvamile, kuhlanganiswe nokuhlaziywa kwedatha yomlando, kuvumela ukuhlonza izitayela kanye nezimpawu zokuxwayisa zakuqala zezinkinga ezingaba khona. Ngokungenela ngaphambi kokuba kufinyelelwe imingcele ebalulekile yokushisa, abasebenzi bokulungisa bangavimbela umonakalo omkhulu kanye nesikhathi esibizayo sokuphumula.

2. Ukuhlolwa Kokuguga Okushisayo

Ukuhlolwa kokuguga okushisa kuhilela ukufaka ama-transformer windings emazingeni okushisa aphezulu isikhathi eside. Le nqubo yokuguga esheshisiwe ilingisa imiphumela yesikhathi eside yamazinga okushisa aphezulu, okuvumela ukuhlolwa kokuwohloka kokushisa noma ubuthakathaka obungaba khona. Ngokusebenzisa izinyathelo zokuvimbela ngokusekelwe emiphumeleni etholakele, isikhathi sokuphila se-transformer singandiswa kakhulu.

3. Imithetho Yokulungisa

Ukusebenzisa uhlelo lokulungisa oluchazwe kahle kusiza ukuqinisekisa ukusebenza kahle kwe-transformer. Lokhu kuhlanganisa ukuhlolwa okuvamile, ukuhlanzwa kwezinhlelo zokupholisa, kanye nokufakwa kwezingxenye ezigugile ngesikhathi esifanele. Izikhawu zokulungisa kufanele zivumelane nezimo zokulayisha ze-transformer, izici zemvelo, kanye nezincomo ezithile zomkhiqizi.

4. Ukuthuthukiswa Kokupholisa

Ukuthuthukisa izindlela zokupholisa ze-transformer kunganciphisa ngempumelelo ukwenyuka kwezinga lokushisa okujiyile. Ukuthuthukiswa okufana nokwengeza amafeni okupholisa engeziwe noma ukuthuthukisa amapayipi omoya kungathuthukisa ukushabalaliswa kokushisa. Izindlela zokupholisa ezisebenzayo, njengezinhlelo zokupholisa uwoyela noma uketshezi, nazo zingasetshenziswa, ikakhulukazi kuma-transformer anomthamo ophezulu asebenza ezimweni ezinzima.

5. Ukuxilongwa Nokulungiswa Kwephutha

Ukuhlolwa okuvamile kanye nezinqubo zokuxilonga zidlala indima ebalulekile ekuqinisekiseni impilo ye-transformer. Ukuhlaziywa kwegesi encibilikisiwe (i-DGA) kungabona amaphutha angaba khona ngokuhlola ukugcwala kwamagesi ancibilikisiwe ku-oyela we-transformer. Ama-windings angalungile, njenge-shorted noma i-open circuits, angatholakala ngokuhlolwa kukagesi. Ukulungiswa nokufakwa esikhundleni kwawo kufanele kwenziwe ngokushesha ukuze kuvinjelwe umonakalo owengeziwe futhi kugcinwe ukusebenza okuthembekile.

Isiphetho:

Ukugcinwa kahle kwama-transformer kubalulekile ukuqinisekisa ukusatshalaliswa okuqhubekayo nokusebenza kahle kwamandla kagesi. Indima yokushisa okugoqekayo ayinakweqiswa kulokhu. Ukuqapha izinga lokushisa okugoqekayo, ukugcina ukulingana kokushisa, ukuvimbela ukuguga kokushisa, kanye nokusebenzisa amasu okulungisa asebenzayo kubalulekile ekwandiseni impilo ye-transformer, ukunciphisa isikhathi sokungasebenzi, kanye nokuqinisekisa ukuhlinzekwa kwamandla okuphephile nokuthembekile.
