Indlela yokulinganisa ilahleko ye-dielectric ye-transformer

Okokuqala, sinokuqonda ukuba ilahleko ye-dielectric kukuba i-dielectric iphantsi kwesenzo sentsimi yombane.Ngenxa yokufudumeza kwangaphakathi, kuya kuguqula amandla ombane kumandla obushushu kwaye adle.Le nxalenye yamandla asetyenzisiweyo ibizwa ngokuba yi-dielectric loss.

Ilahleko ye-Dielectric ayidli kuphela amandla ombane, kodwa iphinda ifudumale izixhobo zezixhobo kwaye ichaphazele ukusebenza kwayo ngokuqhelekileyo.Ukuba ilahleko ye-dielectric inkulu, iya kubangela ukutshisa okuphakathi, okubangela umonakalo kwi-insulation, ngoko ke ilahleko encinci ye-dielectric, ingcono.Oku kukwangomnye wemigangatho ebalulekileyo yomgangatho we-dielectric kwintsimi yombane ye-AC.

Makhe sithethe malunga nendlela yokusebenzisa i-dielectric loss tester ukulinganisa ilahleko ye-dielectric ye-transformer.Emva kokuba siqale isixhobo sokulinganisa, ixabiso lokumisela umbane ophezulu lithunyelwa kunikezelo lwamandla ombane oguquguqukayo, kwaye unikezelo lwamandla ombane oluguquguqukayo lusebenzisa i-algorithm ye-PID ukulungelelanisa ngokucothayo imveliso kwixabiso eliza kusekwa, emva koko isiphaluka esilinganisiweyo siya thumela amandla ombane aphezulu alinganisiweyo kunikezelo lwamandla ombane oguquguqukayo, kwaye emva koko Ulungelelanise umbane ophantsi ukuphumeza imveliso echanekileyo yombane ophezulu.Ngale ndlela, ngokucwangcisa i-wiring elungileyo / umva, isixhobo siya kukhetha ngengqondo kwaye ngokuzenzekelayo igalelo kwaye sitshintshe uluhlu ngokuhambelana novavanyo lwangoku lwesekethe yokulinganisa.

Xa ulinganisa ilahleko ye-dielectric ye-high-voltage winding ukuya kwi-low-voltage winding kunye negobolondo ye-transformer yamandla, sisebenzisa indlela yokudibanisa umva ukulinganisa.Emva kokuba isixhobo kunye ne-transformer yamandla zixhunywe ngokuchanekileyo, sisebenzisa i-frequency eyahlukeneyo, umlinganiselo we-voltage ye-10kV, kunye nendlela yokudibanisa ebuyela umva.Le ndlela isetyenziswa xa i-terminal yokulinganisa i-low-voltage okanye i-terminal yesibini yento yokuvavanya ayikwazi ukugqunywa emhlabeni kwaye isekelwe ngokuthe ngqo.Isixhobo samkela ukuguqulwa kweFourier ukucoca ukuphazamiseka kunye nokwahlula amaza amaninzi omqondiso, ukwenzela ukuba wenze izibalo ze-vector kumgangatho wangoku kunye novavanyo lwangoku, ubale i-capacitance nge-amplitude, kwaye ubale i-tgδ ngokwahlukana kwe-engile.Emva kwemilinganiselo emininzi, isiphumo esiphakathi sikhethwa ngokuhlelwa.Emva kokuba umlinganiselo uphelile, isiphaluka sokulinganisa siya kukhupha ngokuzenzekelayo umyalelo wokuhla.Ngeli xesha, unikezelo lwamandla oluguquguqukayo luya kuhla kancinci luye ku-0.
