Isiphazamisi seVacuum ye-40.5kV TD-40.5/2500-31.5(163)

Isiphazamisi sevacuum, ekwaziwa ngokuba yityhubhu yokutshintsha ivacuum, lelona candelo lingundoqo lokutshintsha kwamandla ombane aphezulu.Isetyenziswa ikakhulu kuthumelo lwamandla kunye nenkqubo yolawulo lokusasazwa, kwaye ikwasetyenziswa kwiinkqubo zokuhambisa isinyithi, umgodi, i-petroleum, iikhemikhali, uloliwe, usasazo, unxibelelwano kunye nokufudumeza okuphakamileyo kwimizi-mveliso.Isiphazamisi se-vacuum sineempawu zokulondoloza amandla, ukugcinwa kwezinto eziphathekayo, ukuthintela umlilo, ubungqina bokuqhuma, umthamo omncinci, ubomi obude, iindleko zokugcinwa okuphantsi, ukusebenza okuthembekileyo kwaye akukho ngcoliseko.Ukutshintsha komthwalo kusetyenziselwa ikakhulu kubasebenzisi be-terminal yegridi yamandla.Xa i-voltage frequency yamandla isondele kwi-zero, kwaye kwangaxeshanye, ngenxa yokunyuka komgama wokuvula umnxeba, I-plasma ye-arc vacuum isasazeka ngokukhawuleza.Emva kokuba i-arc yangoku idlula i-zero, i-medium kwi-gap yoqhagamshelwano itshintsha ngokukhawuleza ukusuka kumqhubi ukuya kwi-insulator, ngoko ke i-current iyanqunyulwa.Ngenxa yesakhiwo esikhethekileyo soqhagamshelwano, i-gap yoqhagamshelwano iya kuvelisa intsimi yamagnetic longitudinal ngexesha le-arcing.Le ntsimi yamagnetic inokwenza i-arc isasazwe ngokulinganayo kwindawo yoqhagamshelwano, igcine i-arc voltage ephantsi, kwaye yenza igumbi lokucima i-arc ye-vacuum ibe nesantya esiphezulu sokubuyisela amandla e-arc dielectric, okukhokelela kumandla amancinci e-arc kunye nesantya esincinci sokubola.Ngale ndlela, ukuphazamisa amandla akhoyo kunye nobomi benkonzo yesiphazamisi sevacuum buyaphuculwa.
