Umkhiqizo
Isiphazamisi se-Vacuum se-VXG (150)
Incazelo emfushane yomkhiqizo:
Isiphazamisi se-vacuum, esaziwa nangokuthi i-vacuum switch tube, siyingxenye eyinhloko yeswishi yamandla kagesi aphezulu aphakathi nendawo.Umsebenzi oyinhloko wesiphazamisi se-vacuum ukwenza isekethe ye-voltage ephakathi nendawo nephezulu inqamule ukunikezwa kwamandla kwegumbi lokucisha i-arc ye-vacuum yegobolondo le-ceramic ngokusebenzisa ukufakwa okuhle kakhulu kwe-vacuum ngaphakathi kweshubhu, engacisha ngokushesha i-arc futhi icindezele amandla amanje. , ukuze kugwenywe izingozi nezingozi.
Kuma-circuit breaker, izinto zokuxhumana ze-vacuum-interrupter ngokuyinhloko ziyingxubevange ye-copper-chromium engu-50-50.Angase enziwe ngokushisela ishidi lengxubevange ye-copper-chrome endaweni engaphezulu nephansi yokuxhumana phezu kwesihlalo sokuxhumana esenziwe ngethusi elingenawo umoya-mpilo.Ezinye izinto, njengesiliva, i-tungsten ne-tungsten compounds, zisetshenziswa kweminye imiklamo yeziphazamisi.Isakhiwo sokuthinta isiphazamisi se-vacuum sinomthelela omkhulu kumthamo waso wokuphuka, ukuqina kukagesi kanye nezinga lokunqunywa kwamanje.
Izingxenye zesiphazamisi se-vacuum kufanele zihlanzwe kahle ngaphambi kokuhlanganiswa, njengoba ukungcola kungase kukhiphele igesi emvilophini yevacuum.Ukuqinisekisa i-voltage ephezulu yokuphuka, izingxenye zihlanganiswa endaweni ehlanzekile lapho uthuli lulawulwa ngokuqinile.
Ngemva kokuba izindawo ezingaphezulu seziqediwe futhi zahlanzwa nge-electroplating kanye nokuhlolwa kokubona kokuvumelana kwendawo yazo zonke izingxenye eyodwa sekwenziwe, isiphazamisi siyahlanganiswa.I-solder ye-vacuum ephezulu isetshenziswa ekuhlanganiseni kwezingxenye, izingxenye zihambisana, futhi iziphazamisi zilungiswa.Njengoba ukuhlanzeka ngesikhathi sokuhlanganiswa kubaluleke kakhulu, yonke imisebenzi yenziwa ngaphansi kwezimo zegumbi elihlanzekile elinesiphephetha-moya.
Abakhiqizi be-vacuum-interrupter babhekana nalokhu kukhathazeka ngokukhetha izinto zokuxhumana kanye nemiklamo ukuze banciphise ukusika kwamanje.Ukuze kuvikelwe okokusebenza ekuqineni ngokweqile, ama-switchgear e-vacuum ngokuvamile ahlanganisa izibambisi zokuhlinzwa.
Igumbi lokucisha i-arc le-vacuum lihlukaniswe laba yigumbi lokucisha i-arc le-breaker circuit, switch switch kanye ne-vacuum contactor.Igumbi lokucisha i-arc le-circuit breaker lisetshenziselwa ikakhulukazi iziteshi ezingaphansi kanye nezinsiza zegridi yamandla emkhakheni wamandla, futhi igumbi lokucisha i-arc lokushintsha komthwalo kanye ne-vacuum contactor lisetshenziselwa ikakhulukazi abasebenzisi bokugcina begridi yamandla.
