Inqanaba le-insulation ye-transformer

Njengesixhobo esibalulekileyo sombane kwinkqubo yamandla, inqanaba lokufakelwa kwe-transformer lihambelana ngokuthe ngqo nokusebenza okukhuselekileyo kunye nokuzinza kwenkqubo yamandla. Inqanaba lokufakelwa kwe-insulation yikhono le-transformer yokumelana ne-overvoltages eyahlukeneyo kunye ne-voltage ephezulu yokusebenza kwexesha elide ngexesha lokusebenza, kwaye yinto ephambili engenakukuhoywa ekuyilweni, ekwenzeni, ekusebenzeni nasekugcinweni kwe-transformer.

1. Inkcazo yenqanaba lokufakelwa kwe-insulation level ye-insulation level ibhekisela kwikhono le-insulation structure ye-transformer yokugcina ingqibelelo kunye nokhuseleko xa imelana ne-overvoltages eyahlukeneyo kunye ne-voltages yokusebenza kwexesha elide. Oku kubandakanya inqanaba le-voltage elinokunyamezela ngokubambisana nesibambisi sombane esikhuselayo kwaye ngokuthe ngqo kuxhomekeke kumbane ophezulu we-Um wesixhobo.

2. Ubume be-insulation ye-transformer Ngokubhekiselele ekubeni inqanaba le-insulation yesiphelo somgca we-winding kunye nenqaku elingathathi hlangothi lifanayo, i-transformer inokwahlulwa ibe yimigangatho emibini yokugquma: i-insulation epheleleyo kunye ne-graded insulation. I-transformer ene-insulation structure ine-insulation level efanayo yesiphelo somgca we-winding kunye nendawo engathathi hlangothi, inomda ophezulu we-insulation, kwaye ifanelekile kubaguquli abanamanqanaba aphezulu ombane kunye neendawo zokusebenza ezinzima. I-transformer ene-graded insulation structure ibeka amanqanaba ahlukeneyo e-insulation phakathi kwesiphelo somgca wokuvala kunye nenqaku elingathathi hlangothi ngokweemfuno zangempela zokwandisa uyilo lokufakelwa kunye nokunciphisa iindleko.

3. Uvavanyo lwenqanaba lokufakelwa kwe-insulation ye-transformer Ukuqinisekisa ukuba inqanaba lokufakelwa kwe-transformer lihlangabezana neemfuno zokuyila, uchungechunge lweemvavanyo zokufakelwa luyafuneka. Kwiziguquli ezinomgangatho wombane wama-220kV nangaphantsi, i-1-minute-frequency yamandla ombane imelana novavanyo lombane kunye novavanyo lwe-voltage ye-impulse idla ngokuqhutywa ukuvavanya amandla abo okugquma. Kwiziguquli ezinamazinga aphezulu ombane, iimvavanyo ezintsonkothileyo zempembelelo nazo ziyafuneka. Kuvavanyo lwefektri, uvavanyo lokumelana nombane luhlala luqhutywa ngaphezulu kwe-voltage ephindwe kabini ukulinganisa ngaxeshanye ukuvavanya ukusebenza kwe-insulation ye-insulation ephambili kunye nokufakwa kwe-longitudinal.

Ukongezelela, ukulinganisa ukunyanzeliswa kwe-insulation, umlinganiselo we-absorption kunye ne-polarization index of the winding kunye ne-bushing kwakhona yindlela ebalulekileyo yokuvavanya imeko yonke yokugquma kwe-transformer. Le milinganiselo inokubona ngokufanelekileyo ukufuma okupheleleyo kwe-insulation transformer, ukufuma okanye ukungcola kumphezulu wamacandelo, kunye neziphene ezigxininisiweyo zokungena.

4. Izinto ezichaphazela inqanaba le-insulation ye-transformer Ngexesha lokusebenza kwe-transformer, izinto ezichaphazela inqanaba le-insulation ikakhulu ziquka ukushisa, umswakama, indlela yokukhusela ioli kunye nomphumo wokugqithisa. I-1) Ubushushu: Ubushushu buyinto ephambili echaphazela ukusebenza kwe-insulation ye-transformer. Ukusebenza kwe-insulation ye-insulating material iyancipha ngokunyuka kweqondo lokushisa, kwaye ubukho bomswakama kwioli buya kukhawuleza ukuguga kwe-insulation. Ngoko ke, ukulawula ubushushu bokusebenza kwe-transformer kunye nokugcina imeko efanelekileyo yezinto ezikhuselayo ziyimilinganiselo ebalulekileyo yokuphucula umgangatho wokufakelwa.

2) Umswakama: Ubukho bomswakama buya kukhawulezisa ukuguga kwezinto zokukhusela kunye nokunciphisa ukusebenza kwayo. Ngoko ke, ngexesha lokusebenza kwe-transformer, umswakama wendawo kufuneka ulawulwe ngokungqongqo ukukhusela izinto ezikhuselayo ukuba zingabi namanzi.

I-3) Indlela yokukhusela i-oyile: Iindlela ezahlukeneyo zokukhusela ioli zineempembelelo ezahlukeneyo ekusebenzeni kwe-insulation. Ekubeni i-oyile ye-oyile ye-transformer etywiniweyo ifakwe emoyeni, inokuthintela ngokufanelekileyo i-volatilization kunye nokusabalalisa kwe-CO kunye ne-CO2 kwioli, ngaloo ndlela igcina ukusebenza kakuhle kweoli ye-insulating.

I-4) Umphumo wokugqithiswa kwe-overvoltage: Umphumo wokugqithiswa kwe-overvoltage yenye into ebalulekileyo echaphazela inqanaba le-insulation ye-transformer. Zomibini i-overvoltage yombane kunye ne-overvoltage yokusebenza inokubangela umonakalo kwi-insulation structure ye-transformer. Ngoko ke, xa uyila kunye nokusebenza kwe-transformer, impembelelo yokugqithisa i-overvoltage kufuneka iqwalaselwe ngokupheleleyo kwaye amanyathelo okukhusela ahambelanayo kufuneka athathwe.
