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

Ukuhlolwa kwe-AC ukumelana ne-voltage ye-transformer kuwukuhlola lapho i-voltage yokuhlola ye-AC ye-sinusoidal imvamisa ye-AC eyedlula ukuphindaphinda okuthile kwe-voltage elinganiselwe isetshenziswa ekujikeni kwe-transformer ehloliwe kanye ne-bushing, futhi ubude besikhathi ngu-1min.Inhloso iwukusebenzisa 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 ephumelela kakhulu yokuhlonza amandla okufakelwa kwe-transformer, futhi kuyiphrojekthi ebalulekile yokuhlola ukuqinisekisa ukusebenza okuphephile kwe-transformer nokugwema ukuvela kwezingozi zokufakelwa.Ukuhlolwa kwe-AC ukumelana nomthamo we-voltage kungathola ukuthi ukufakwa okuyinhloko kwe-transformer kunomswakama futhi kuneziphambeko ezigxilile, njengokuqhekeka kwe-insulation eyinhloko yama-windings, ama-winding axekethile Amaphutha afana nokufuduka, ibanga le-lead insulation alanele, futhi ukungcola kunamathiselwe ku-insulation. .Ukuhlolwa kwe-AC ukumelana ne-voltage kuwukuhlola okulimazayo ekuhlolweni kokufakwa ngaphakathi.Kumele kwenziwe ngemuva kokuthi ezinye izivivinyo ezingabhubhisi (ezifana nokumelana nokufakwa kwe-insulation kanye nokuhlolwa kwesilinganiso sokumuncwa, ukuhlolwa kokuvuza kwe-DC, ukulungiswa kokulahleka kwe-dielectric kanye nokuhlolwa kukawoyela ovikelayo) sekufanelekile..Ngemuva kokuthi lesi sivivinyo sesidlulile, i-transformer ingafakwa ekusebenzeni.Ukuhlolwa kwe-AC ukumelana nogesi kuwukuhlola okubalulekile, Ngakho-ke, imithetho yokuhlola yokuvimbela ibeka ukuthi ama-transformer ane-10kV nangaphansi kufanele ahlolelwe i-AC ukumelana nogesi ngemva kweminyaka engu-1 ~ 5, 66kV nangaphansi ngemva kokulungiswa kabusha, ngemva kokushintsha ama-winding nalapho kudingeka.

Indlela yokuhlola

(1) Izintambo

I-AC yangaphandle imelana nezintambo zokuhlola amandla kagesi kuma-transformer amancane naphakathi nendawo angaphansi kuka-35kV.Wonke ama-windings kufanele ahlolwe.Ngesikhathi sokuhlolwa, izintambo eziholayo zesigaba ngasinye kufanele zifinyezwe ndawonye.Uma kukhona intambo eholayo endaweni engathathi hlangothi, intambo eholayo kufanele futhi ibe mfushane-ijikelezwe nesigaba sesithathu.

(2) Ukuhlola Amandla Kagesi

Izinga lokuhlola ukunikezwa libeka ukuthi i-transformer amandla ayo angaphansi kuka-8000kV futhi amandla ayo ogesi alinganiselwe angaphansi kuka-110kV kufanele ahlolwe i-AC ukumelana nogesi ngokwezinga lokuhlola amandla kagesi elisohlwini Lwesithasiselo I sezinga.

Imithetho yokuhlola yokuvimbela iyacacisa: inani le-voltage yokuhlola yama-transformer acwiliswe uwoyela lichazwe kuthebula lemithetho (ukuhlolwa okuvamile kungena esikhundleni senani lamandla kagesi elijikayo ngokuya ngengxenye).Lapho wonke ama-windings we-ome-type transformer eshintshwa, inani le-voltage yokuhlolwa kwefekthri lizosetshenziswa;lapho ama-windings e-transformer yohlobo olomile eshintshwa kancane futhi ahlolwe ngezikhathi ezithile, inani le-voltage yokuhlolwa kwefekthri lizoba izikhathi ezingu-0.85.
