Ukuhlolwa kwe-no-load ye-transformer kuwukuhlola ukulinganisa ukulahlekelwa okungenamthwalo kanye nokungalayishi okwamanje kwe-transformer ngokusebenzisa i-voltage elinganiselwe ye-sine wave elinganiselwe imvamisa elinganiselwe ukusuka ekujikeni ngapha nangapha kwe-transformer, futhi amanye ama-winding avulekile-circuited.I-no-load current ichazwa njengephesenti le-No-load yamanje elinganisiwe kuya kweyamanje elinganiselwe okungukuthi, echazwa ngokuthi i-IO.
Umthamo wesiguquli sochungechunge lwe-HV HIPOT GDBR kanye nesihloli esingalayishi
Uma kunomehluko obalulekile phakathi kwevelu elinganiswe ukuhlolwa kanye nenani lokubala ledizayini, ivelu yefekthri, inani lohlobo olufanayo lwesiguquli noma inani ngaphambi kokulungiswa kabusha, isizathu kufanele sitholakale.
Ukulahlekelwa okungenamthwalo ikakhulukazi ukulahlekelwa kwensimbi, okungukuthi, ukulahlekelwa kwe-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy okudliwe ku-iron core.Uma ungalayishi, amandla ashukumisayo ageleza endaweni yokusonta okuyinhloko aphinde akhiqize ukulahlekelwa ukumelana, okunganakwa uma i-excitation current incane.Ukulahlekelwa okungenamthwalo kanye nokungalayishwa kwamanje kuncike ezintweni ezifana nomthamo we-transformer, ukwakheka kwengqikithi, ukukhiqizwa kweshidi lensimbi ye-silicon kanye nenqubo yokukhiqiza umgogodla.
Izizathu eziyinhloko zokwenyuka kokulahlekelwa okungenamthwalo kanye nokungalayishwa kwamanje yilezi: ukufakwa okungalungile phakathi kwamashidi ensimbi ye-silicon;isifunda esifushane sengxenye ethile yamashidi ensimbi ye-silicon;ukuphenduka kwe-short-circuit okwakhiwa ngokulimala kokufakwa kwamabhawodi ayisisekelo noma amapuleti okucindezela, amajoka angaphezulu nezinye izingxenye;Ishidi lensimbi ye-silicon likhululekile, futhi ngisho negebe lomoya livela, okwandisa ukumelana namagnetic (ikakhulukazi kwandisa amandla amanje angenayo);umzila kazibuthe wakhiwe ishidi lensimbi ye-silicon ejiyile (ukulahleka okungekho umthwalo kuyakhuphuka kanye nokuncipha komthwalo wamanje);insimbi ye-silicon ephansi isetshenziswa Izingcezu (ezivame kakhulu kuma-transformers amancane okusabalalisa);amaphutha ahlukahlukene asongwayo, okuhlanganisa i-inter-turn short circuit, i-parallel branch short circuit, inani elihlukile lokujika egatsheni ngalinye elihambisanayo, kanye nokutholwa kwe-ampere-turn okungalungile.Ukwengeza, ngenxa yokubekwa phansi okungalungile kwesekethe kazibuthe, njll., ukulahlekelwa okungekho umthwalo kanye nokwanda kwamanje nakho kuzobangelwa.Kuma-transformer amancane naphakathi nendawo, ubukhulu bomthungo oyinhloko bungathinta kakhulu i-no-load yamanje ngesikhathi senqubo yokukhiqiza.
Lapho wenza ukuhlola okungenamthwalo we-transformer, ukuze kube lula ukukhethwa kwamathuluzi nemishini futhi kuqinisekiswe ukuphepha kokuhlolwa, ithuluzi kanye nokunikezwa kwamandla ngokuvamile kuxhunywe ohlangothini lwe-low-voltage, kanye nohlangothi lwe-voltage ephezulu. ishiywe ivuliwe.
Ukuhlolwa kokungalayishi ukukala ukulahleka okungalayishi kanye nokungalayishi ngaphansi kwe-voltage elinganiselwe.Ngesikhathi sokuhlolwa, uhlangothi lwe-high-voltage luvulekile, futhi uhlangothi oluphansi lwe-voltage lucindezelwa.I-voltage yokuhlola i-voltage elinganiselwe yohlangothi lwe-low-voltage.I-voltage yokuhlola iphansi, futhi amandla okuhlola angamaphesenti ambalwa wamanje olinganiselwe.noma izinkulungwane.
I-voltage yokuhlola yokuhlola okungenamthwalo yi-voltage elinganiselwe yohlangothi lwe-voltage ephansi, futhi ukuhlolwa kwe-no-load ye-transformer ngokuyinhloko kulinganisa ukulahlekelwa okungekho umthwalo.Ukulahlekelwa okungenamthwalo ikakhulukazi ukulahlekelwa kwensimbi.Ubukhulu bokulahlekelwa kwensimbi bungabhekwa buzimele ngobukhulu bomthwalo, okungukuthi, ukulahlekelwa ngaphandle komthwalo kufana nokulahlekelwa kwensimbi ekulayisheni, kodwa lokhu kubhekisela esimweni ku-voltage elinganiselwe.Uma i-voltage ichezuka enanini elilinganiselwe, njengoba ukungeniswa kazibuthe kumongo we-transformer kusigaba sokugcwala kwejika lamagnetization, ukulahleka okungenamthwalo kanye nokungalayishwa kwamanje kuzoshintsha kakhulu.Ngakho-ke, ukuhlolwa kwe-no-load kufanele kwenziwe ku-voltage elinganiselwe.
