Izinga le-insulation ye-transformer

Njengemishini ebalulekile kagesi ohlelweni lwamandla, izinga lokufakelwa kwe-transformer lihlobene ngokuqondile nokusebenza okuphephile nokuzinzile kwesistimu yamandla. Izinga le-insulation liyikhono le-transformer lokumelana nama-overvoltages ahlukahlukene kanye ne-voltage ephezulu yokusebenza yesikhathi eside ngesikhathi sokusebenza, futhi iyisici esiyinhloko esingenakunakwa ekuklanyeni, ekukhiqizeni, ekusebenzeni nasekugcinweni kwe-transformer.

1. Incazelo yezinga le-insulation ye-transformer Izinga lokufakelwa libhekisela ekhonweni le-insulation structure ye-transformer ukugcina ubuqotho nokuphepha lapho imelana no-overvoltage ehlukahlukene kanye ne-voltage yokusebenza yesikhathi eside. Lokhu kufaka phakathi izinga le-voltage elingabekezelelwa ngokuhambisana nesibambisi sombani esivikelayo futhi kuncike ngokuqondile ku-voltage enkulu Um wezinto zokusebenza.

2. Isakhiwo se-insulation se-transformer Ngokusho kokuthi izinga lokufakwa kwe-insulation line ekupheleni komugqa ovunguzayo kanye nephuzu elingathathi hlangothi liyafana, i-transformer ingahlukaniswa ibe yizakhiwo ezimbili zokufakelwa: ukufakwa okugcwele kanye nokufakwa okulinganiselwe. I-transformer ene-insulation structure egcwele inezinga elifanayo lokufakwa kwe-insulation lokuphela komugqa ojikajikayo kanye nephuzu elingathathi hlangothi, inomkhawulo ophezulu wokufakwa kwe-insulation, futhi ifanele ama-transformer anamazinga aphezulu kagesi kanye nezindawo zokusebenza eziyinkimbinkimbi. I-transformer enesakhiwo sokufaka ungqimba esilinganiselwe isetha amazinga ahlukene wokuhlukanisa phakathi komugqa osongayo kanye nephoyinti elingathathi hlangothi ngokwezidingo zangempela zokuthuthukisa umklamo wokuhlukanisa nokunciphisa izindleko.

3. Ukuhlolwa kwezinga le-insulation ye-transformer Ukuqinisekisa ukuthi izinga lokufakelwa kwe-transformer lihlangabezana nezidingo zokuklama, uchungechunge lwezivivinyo zokuhlola luyadingeka. Kuma-transformer anezinga le-voltage engu-220kV nangaphansi, imvamisa yamandla eyiminithi elingu-1 imelana nokuhlolwa kwe-voltage kanye nokuhlolwa kwe-voltage ye-impulse voltage ngokuvamile kuyenziwa ukuze kuhlolwe amandla awo okushisa. Kuma-transformer anamazinga aphezulu kagesi, ukuhlolwa kwe-impulse okuyinkimbinkimbi kakhulu kuyadingeka. Ezivivinyweni zasefekthri, ukuhlolwa kokumelana ne-voltage kuvame ukwenziwa ngaphezu kokuphindwe kabili kwe-voltage elinganiselwe ukuze kuhlolwe ngasikhathi sinye ukusebenza kwe-insulation ye-insulation eyinhloko kanye nokufakwa kwe-longitudinal.

Ukwengeza, ukulinganisa ukumelana nokufakwa kwe-insulation, isilinganiso sokumunca kanye nenkomba ye-polarization ye-winding kanye ne-bushing futhi kuyindlela ebalulekile yokuhlola isimo sokushisa sonke se-transformer. Lezi zilinganiso zingakwazi ukubona ngokuphumelelayo umswakama jikelele we-insulation ye-transformer, umswakama noma ukungcola ebusweni bezingxenye, kanye nokukhubazeka okugxilile kokungena.

4. Izici ezithinta izinga lokufakelwa kwe-transformer Ngesikhathi sokusebenza kwe-transformer, izici ezithinta izinga lokufaka ngokuyinhloko zihlanganisa izinga lokushisa, umswakama, indlela yokuvikela uwoyela kanye nomphumela wokugcwala ngokweqile. I-1) Izinga lokushisa: Izinga lokushisa liyisici esibalulekile esithinta ukusebenza kwe-insulation ye-transformer. Ukusebenza kwe-insulation ye-insulating material kuncipha ngokunyuka kwezinga lokushisa, futhi ukuba khona komswakama emafutheni nakho kuzosheshisa ukuguga kwe-insulation. Ngakho-ke, ukulawula izinga lokushisa lokusebenza kwe-transformer nokugcina isimo esihle se-insulating material yizinyathelo ezibalulekile zokuthuthukisa izinga lokufakelwa.

2) Umswakama: Ukuba khona komswakama kuzosheshisa ukuguga kwezinto zokuvikela futhi kunciphise ukusebenza kwayo kokufakwa. Ngakho-ke, ngesikhathi sokusebenza kwe-transformer, umswakama we-ambient kufanele ulawulwe ngokuqinile ukuze kuvinjwe izinto zokuvikela ukuthi zingabi manzi.

3) Indlela yokuvikela uwoyela: Izindlela ezihlukene zokuvikela uwoyela zinemiphumela ehlukile ekusebenzeni kokufakwa. Njengoba indawo yamafutha ye-transformer evaliwe ifakwe emoyeni, ingavimbela ngokuphumelelayo ukuguquguquka nokusabalalisa kwe-CO ne-CO2 emafutheni, ngaleyo ndlela igcine ukusebenza kahle kwamafutha okuvikela.

I-4) Umphumela we-Overvoltage: Umphumela we-Overvoltage ungenye into ebalulekile ethinta izinga lokufakwa kwe-transformer. Kokubili i-overvoltage yombani nokusebenza ngokweqile kungase kubangele ukulimala kwesakhiwo sokufakelwa kwe-transformer. Ngakho-ke, lapho uklama futhi usebenzisa i-transformer, umthelela we-overvoltage kufanele ucatshangelwe ngokugcwele futhi izinyathelo zokuvikela ezihambisanayo kufanele zithathwe.
