Inhloso kanye nendlela yokuhlola ye-AC ukumelana nokuhlolwa kwe-voltage ye-transformer

I-transformer AC ukumelana nokuhlolwa kwe-voltage isivivinyo lapho i-voltage yokuhlola amandla e-sinusoidal imvamisa ye-AC eyedlula ukuphindaphinda okuthile kwe-voltage elinganisiwe isetshenziswa kuma-windings we-transformer ehloliwe kanye ne-bushing, futhi ubude besikhathi buyi-1 min.Inhloso yaso ukusebenzisa i-voltage yokuhlola ephakeme kune-multiple ethize ye-voltage elinganiselwe ukuze ithathele indawo ye-overvoltage yomoya kanye nokweqile kwangaphakathi ukuze kuhlolwe ukusebenza kokufakwa kwe-transformer.Kuyindlela ephumelelayo yokuhlonza amandla okufaka ama-transformer, futhi kuphinde kube yinto ebalulekile yokuhlola ukuqinisekisa ukusebenza okuphephile kwama-transformer nokugwema izingozi zokufakelwa.Ukuqhuba ukuhlolwa kwe-AC ukumelana ne-voltage kungathola umswakama kanye nokukhubazeka okugxilile ku-insulation eyinhloko ye-transformer, njengemifantu ebambayo yokufaka ama-insulator, ukuxega okumazombezombe kanye nokugudluzwa , Ibanga le-lead insulation alanele, futhi ukufakwa kwe-insulation kunamathela ezimeni ezinjengokungcola.

Ukuhlolwa kwe-AC ukumelana ne-voltage kuwukuhlola okulimazayo ekuhlolweni kokufakwa ngaphakathi.Kumelwe ihlolwe ngemva kokuba ezinye izivivinyo ezingabhubhisi (ezifana nokumelana nokufakwa kwe-insulation kanye nokuhlolwa kwesilinganiso sokumuncwa, ukuhlolwa kokuvuza kwe-DC, ukusika ukulungiswa kokulahlekelwa kwe-dielectric kanye nokuhlolwa kukawoyela wokufaka insulating) sekufanelekile..Ngemuva kokuthi lokhu kuhlolwa sekufanelekile, i-transformer ingafakwa ekusebenzeni.Ukuhlolwa kwe-AC ukumelana ne-voltage kuwukuhlola okubalulekile.Ngakho-ke, imithetho yokuhlola yokuvimbela ibeka ukuthi i-transformer ene-10kV nangaphansi, eminyakeni engu-1 ~ 5, 66kV nangaphansi, kufanele ibhekane ne-AC ukumelana nogesi ngemva kokulungiswa kabusha, ngemva kokushintshwa kwama-windings nalapho kudingeka ukuhlolwa.

Indlela yokuhlola

(1) Izintambo zokuhlola Iziguquli zamandla amancane namaphakathi angaphansi kuka-35kV zisetshenziswa nge-AC ukumelana nezintambo zokuhlola amandla kagesi.Wonke ama-windings kufanele ahlolwe.Ngesikhathi sokuhlolwa, izintambo eziholayo zesigaba ngasinye kufanele zifinyezwe ndawonye.Uma iphoyinti elingathathi hlangothi linezintambo zomthofu, izintambo eziholayo kufanele futhi zibe mfushane-zijikeleze ngezigaba ezintathu.

(2) I-voltage yokuhlola Izinga lokuhlola i-handover libeka ukuthi ama-transformer anesisindo esingaphansi kuka-8000kV kanye ne-voltage elinganiselwe ephendukayo engaphansi kuka-110kV azohlolwa i-AC ukumelana ne-voltage ngokuvumelana nezindinganiso zokuhlola amandla kagesi ezisohlwini Lwesithasiselo 1 sezinga.Imithetho yokuhlola yokuvimbela iyacacisa: Inani le-voltage yokuhlola ye-transformer ecwiliswe uwoyela ichazwe kuthebula lokulawula (ukuhlola okuvamile kuthatha indawo yevelu ye-voltage ejikayo ngengxenye).Kuma-transformer ohlobo olomile, lapho wonke ama-winding eshintshwa, landela inani le-voltage yokuhlolwa kwemboni;ukuze kushintshwe ingxenye yama-windings nokuhlola okuvamile, cindezela izikhathi ezingu-0.85 inani le-voltage yokuhlolwa kwasembonini.

(3) Izinyathelo zokuqapha Ngaphezu kwezinyathelo ezijwayelekile ze-AC ukumelana nokuhlolwa kwe-voltage, amaphuzu alandelayo kufanele aqashelwe ngokuya nezici ze-transformer:

1) I-transformer yokuhlola kufanele ifakwe idivayisi yohambo lokuvikela i-overcurrent.

2) I-AC ukumelana nokuhlolwa kwe-voltage ye-transformer yezigaba ezintathu ayidingi ukwenziwa ngezigaba.Kodwa-ke, zonke izintambo eziholayo zezigaba ezintathu zokuvuthwa okuhlanganisiwe kufanele zibe mfushane ngaphambi kokuhlolwa, ngaphandle kwalokho ngeke kuthinte kuphela ukunemba kwe-voltage yokuhlola, kodwa kungase kufake engozini ukufakwa okuyinhloko kwe-transformer.

I-3) Imithetho yokuhlola yokuvimbela ikhomba ukuthi kuma-transformer afakwe wonke angaphansi kuka-66kV, lapho izimo zesayithi zingatholakali, imvamisa yokwakhiwa kwangaphandle kuphela yokumelana nokuhlolwa kwe-voltage engenziwa.

4) Kuma-transformer kagesi amaphoyinti azo aphakathi nendawo abuthakathaka kunezinye izingxenye noma ukufakwa kwezigaba, isivivinyo se-AC sangaphandle esimelana ne-voltage esingenhla asinakusetshenziswa, kodwa isingeniso sokumelana nokuhlolwa kwamandla kagesi izikhathi ezingu-1.3 kufanele sisetshenziswe.

I-5) Kumelwe ihlolwe ngemva kokugcwaliswa ngamafutha afanelekayo nokuphumula isikhathi esithile.

6) Kuma-medium-and-capacity-transformer amancane anezinga le-voltage engu-35kV, i-voltage yokuhlola ivunyelwe ukulinganiswa ohlangothini lwe-low-voltage ye-transformer yokuhlola.Kuma-transformer amandla anamandla amakhulu, ukuze ukulinganisa kunembile futhi kuthembekile, i-voltage transformer noma i-electrostatic voltmeter kufanele isetshenziswe.I-voltage yokuhlola ikalwa ngokuqondile ohlangothini lwe-voltage ephezulu.

7) Uma ukukhishwa noma ukuwohloka kwenzeka ngesikhathi sokuhlolwa, yehlisa ngokushesha i-voltage futhi unqamule ukunikezwa kwamandla ukuze ugweme ukwehluleka okukhulisiwe.
