Ukubaluleka koVavanyo lokukhutshelwa kwenxalenye

Yintoni ukukhupha inxalenye?Kutheni le nto izixhobo zombane zifuna uvavanyo lokukhutshwa kancinci?
Ukuqhekeka kwenxalenye yokukhutshwa kombane kwi-insulation yezixhobo zombane, ezinokuthi zenzeke kufuphi ne-conductor okanye kwenye indawo, kuthiwa yi-partial discharge.

Ngenxa yamandla amancinci kwinqanaba lokuqala lokukhutshwa kwenxalenye, ukukhutshwa kwayo akubangeli ngokukhawuleza ukuchithwa kwe-insulation, kwaye i-insulation intact phakathi kwe-electrode engekakhutshwa isenokumelana nombane osebenzayo wesixhobo.Nangona kunjalo, phantsi kwe-voltage yokusebenza kwexesha elide, umonakalo we-insulation obangelwa ukukhutshwa okuyingxenye uyaqhubeka nokuphuhliswa, ekugqibeleni kukhokelela ekuveleni kweengozi ze-insulation.Ixesha elide, izixhobo zamandla ombane aphezulu zisebenzise i-non-voltage kunye nokumelana novavanyo lombane ukujonga imeko yokugquma kunye nokuthintela ukwenzeka kweengozi zokuqhekeka kwe-insulation.Nangona ezi ndlela zovavanyo zingasentla zinokugweba ngokufutshane okanye ngokuthe ngqo ukuthembeka kokugquma, iziphene ezinokuthi zikhuphe inxenye zibaluleke kakhulu.Kunzima ukuyifumana, kwaye i-insulation iya konakala ngexesha lovavanyo lokumelana nombane, ukunciphisa ubomi benkonzo.
Ngokwezibalo zelizwe lam kumonakalo we-transformers ye-110KV nangaphantsi, i-50% ibangelwa ukuphuhliswa ngokuthe ngcembe kokukhutshwa kwenxalenye phantsi kombane osebenzayo.Ngokusebenzisa uvavanyo lokukhupha inxalenye, kunokwenzeka ukufumanisa ukuba kukho ukukhupha inxalenye, ubunzima kunye nendawo ngaphakathi kwesixhobo sokugquma ngexesha, kwaye uthathe amanyathelo afanelekileyo okuthintela iingxaki ngaphambi kokuba zenzeke.Kwiminyaka yakutshanje, i-voltage elinganisiweyo yezixhobo zamandla iye yanda.Kwizixhobo zamandla ombane we-ultra-high, kunokwenzeka ukubuyisela uvavanyo lwexesha elifutshane lokumelana ne-voltage kunye novavanyo lwexesha elide lokukhupha.
Imimiselo efanelekileyo ichaza ukuba izixhobo zombane eziphezulu kufuneka zivavanyelwe ukukhupha inxalenye xa ushiya umzi-mveliso, kwaye emva kovavanyo lwempembelelo yombane, njl. njl., uvavanyo lokukhupha inxalenye kufuneka luqhutywe kwakhona ukuqinisekisa ukuba ukukhutshwa kwenxalenye yesixhobo esishiya. umzi-mveliso ungaphakathi koluhlu olufanelekileyo.Ngexesha lokugadwa komzi-mveliso we-transformer kule venkile, ngokwenene kwakukho inani elithile leenguqu ezingakwazi ukuphuma kumzi-mveliso ngenxa yokukhutshwa okugqithisileyo.
Ukongezelela, ngexesha lokusebenza kwezixhobo, ngenxa yezizathu ezahlukahlukeneyo, ukukhutshwa kwenxalenye yokuqala kunokufaneleka, kwaye kunokuthi kuphuhliswe ngokuthe ngcembe ibe yinto engafanelekiyo, kunye namanqaku amatsha okukhutshwa angenziwa kwakhona.Ngoko ke, umlinganiselo oqhelekileyo wokukhutshwa kwenxalenye yesixhobo sokusebenza ngeyunithi yokusebenza yenye yeendlela ezibalulekileyo zokulawulwa kwe-insulation, kwaye kuyindlela engcono yokugweba ukusebenza okukhuselekileyo kwexesha elide lokugquma.Xa kukho ukungaqhelekanga kwisixhobo, esifana nohlalutyo lwechromatographic oludlula ixabiso lokuqwalaselwa, kuyimfuneko ngakumbi ukwenza uvavanyo lokukhupha inxalenye yokuchonga indawo engaqhelekanga kunye nesidanga.
