Xa i-transformer isebenza kwigridi yamandla, akufuneki nje ukuba ithwale isenzo se-voltage kunye nekhoyo ngoku ekusebenzeni okuqhelekileyo, kodwa iphinde ithwale isenzo seendlela ezahlukeneyo zombane ezingaqhelekanga kunye nezangoku.Ngoko ke, i-transformer kufuneka iyilwe kwaye yenziwe ukuba ibe nokhuseleko olwaneleyo kunye nokuthembeka.Ukhuseleko kunye nokuthembeka kufuneka kubandakanye iinkalo ezininzi ezifana namandla okufakelwa kombane, ukusebenza kwe-thermal kunye namandla omatshini.
Amandla okufakelwa kombane we-transformer yenye yeemeko ezisisiseko zokusebenza okuthembekileyo kwe-transformer.Imiba ekufuneka iqwalaselwe kumandla ombane wokugquma umbane weziguquli zezi: ukuqonda ukuba zeziphi na iintlobo zombane eziguquguqukayo kwigridi yamandla eziya kubonakaliswa kuzo, kwaye zeziphi iindlela zokuvavanya ezisetyenziselwa ukuvavanya ukuba ngaba iinguqu ziyakwazi ukumelana nemiphumo yale mibhobho;ukuqonda iindawo ezahlukeneyo ze-windings Ikhono lokumelana nale mibhobho kunye neempawu zokukhusela izinto ezahlukeneyo zokukhusela kunye nezakhiwo ezisetyenziswa kwicandelo ngalinye.
Ukuze kuqinisekiswe ukuba i-transformers ekhutshwe kwifektri ihlangabezana neemfuno zokusebenza okukhuselekileyo kunye nokuthembekileyo, ngaphezu kokusebenza kwe-insulation kunye nokusebenza kombane we-transformers ukuhlangabezana nemigangatho yelizwe, amandla ombane we-insulation of transformers kufuneka ahlangabezane neemfuno. .Amandla ombane we-transformer yimeko efunekayo yokuvavanya ukusebenza okukhuselekileyo nokuthembekileyo kwe-transformer phantsi kombane osebenzayo oqhelekileyo kunye neemeko ezingaqhelekanga (ezifana nombane wombane, ukugqithisa kombane, njl.).Kuphela ngovavanyo lwala ma-voltages asetyenzisiweyo kunye nokukhutshwa okuyingxenye, kunokutshiwo ukuba i-transformer ineemeko ezisisiseko zokusebenza kwigridi.
Ke ngoko, i-transformer nganye kufuneka ibekwe phantsi kovavanyo olunje ngesantya esifutshane samandla okumelana nombane, i-impulse ukumelana ne-voltage kunye ne-partial discharge measurement.
HV HIPOTGDYD-Uthotho lweseti yovavanyo lweHipot oluzenzekelayo
GDYD-A seriesAutomatic hipot test setluhlobo olutsha olukrelekrele lokumelana nezixhobo zovavanyo lombane olunentsebenzo ephezulu eyilwe yi-HV Hipot ngokwesiseko sohlobo lwe-GDYD-D kwaye ngokwemigangatho yamva nje yoshishino lwamandla esizwe.Indlela engqongqo, esebenzayo kunye nethe ngqo yokuchonga amandla e-dielectric yezixhobo zombane.Iyakwazi ukukhangela ezo ziphene ezigxininisiweyo eziyingozi kakhulu, kwaye zinendima ecacileyo ekugwebeni ukuba izixhobo zamandla zinokuqhubeka nokuthatha inxaxheba ekusebenzeni.Yindlela ebalulekileyo yokuqinisekisa umgangatho wokufakelwa kwesixhobo kunye nokuphepha ukwenzeka kweengozi ze-insulation.Isetyenziselwa ukwenza uvavanyo lwamandla e-dielectric phantsi kombane ochaziweyo kwiimveliso zombane ezahlukeneyo, izinto zombane, izinto zokugquma, njl.njl., ukuvavanya inqanaba lokugquma kwemveliso, ukufumana isiphene sokufakelwa kwemveliso evavanyiweyo, kunye nokulinganisa amandla overvoltage.Isetyenziswa kakhulu kumasebe okuvelisa umbane, amasebe okusebenza kwamandla, iiyunithi zophando lwezenzululwazi kunye namaziko emfundo ephakamileyo.
