Isiphazamisi seVacuum ye-40.5kV TD-40.5/2500-31.5 (160)

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.I-vacuum interrupter ihlukaniswe ngokusetyenziswa kwesiphazamisi kunye nokutshintsha komthwalo.I-interrupter ye-circuit breaker isetyenziswa kakhulu kwi-substation kunye nezibonelelo zegridi yamandla kwisebe lamandla ombane.

Isiphazamisi sevacuum sisixhobo sokufunxa sombane esisebenzisa ivacuum ephezulu ekhuselayo yokucima i-arc kwaye siqonde umsebenzi wokucima wesekethe yamandla ngabafowunelwa ababini abatywinwe kwivacuum.Xa uqhawula umlinganiselo othile wangoku, ngexesha lokwahlulwa koqhagamshelwano oluguquguqukayo kunye noluzinzileyo, lwangoku luyancipha ukuya kwindawo apho abafowunelwa bahlukana nje, okukhokelela ekunyukeni okubukhali kokuchasana phakathi kwee-electrodes kunye nokunyuka ngokukhawuleza kweqondo lokushisa, de Ukukhutshwa kwesinyithi se-electrode evaporation kwenzeka, kwaye kwangaxeshanye, ukuqina kombane okuphezulu kakhulu kuyenziwa, okukhokelela ekuphumeni okunamandla kakhulu kunye nokuqhekeka kwe-gap, okukhokelela kwi-vacuum arc.Xa i-voltage ye-frequency yamandla isondele kwi-zero, kwaye kwangaxeshanye, ngenxa yokunyuka komgama wokuvula uqhagamshelwano, iplasma ye-arc vacuum isasazeka ngokukhawuleza.
