Isiphazamisi sevacuum kwisaphuli sesekethe yombane ophantsi (604)

Kwizikhewu zesekethe, izixhobo zokunxibelelana ne-vacuum-interrupter ngokuyintloko ziyi-50-50 ye-copper-chromium alloy.Zisenokwenziwa ngokuwelda icwecwe le-copper-chrome alloy kwindawo ephezulu kunye nesezantsi yokudibanisa phezu kwesihlalo soqhagamshelwano esenziwe ngobhedu olungenayo i-oksijini.Ezinye izinto, ezifana nesilivere, i-tungsten kunye neekhompawundi ze-tungsten, zisetyenziswa kwezinye iziphazamisi zoyilo.Isakhiwo soqhagamshelwano lwesiphazamisi se-vacuum sinempembelelo enkulu ekuqhekezeni kwayo, ukuqina kombane kunye nenqanaba lokunqunyulwa kwangoku.
Ivacuum interrupter bellows ivumela uqhagamshelwano olushukumayo ukuba luqhutywe ngaphandle kwendawo ebiyelweyo yesiphazamisi, kwaye kufuneka igcine ivacuum yexesha elide ngaphezulu kobomi obulindelekileyo bokusebenza kwesiphazamisi.Imibhobho yenziwe ngensimbi engenasici kunye nobukhulu be-0.1 ukuya kwi-0.2 mm.Ubomi bayo bokudinwa buchatshazelwa bubushushu obuqhutywa kwi-arc.

Ukuze bakwazi ukuhlangabezana neemfuno zonyamezelo oluphezulu kuqheliselo lokwenyani, iimboli zihlala ziphantsi kovavanyo lokunyamezela rhoqo emva kweenyanga ezintathu.Uvavanyo lwenziwa kwi-cabin yovavanyo oluzenzekelayo ngokupheleleyo kunye nohambo oluhlengahlengisiweyo kuhlobo olufanelekileyo.
Iiassemblyna ze-vacuum interrupts ekuqaleni zadityaniswa zaza zadityaniswa kunye kwiziko le-hydrogen-atmosphere.Ityhubhu eqhagamshelwe ngaphakathi kwesiphazamisi yayisetyenziselwa ukukhupha isiphazamisi ngempompo yokufunxa yangaphandle ngelixa isiphazamisi sigcinwe malunga ne-400 °C (752 °F).
Ngaphantsi kweemeko ezithile, i-vacuum circuit breaker inokunyanzela i-current in circuit ukuya kwi-zero phambi kwe-zero yendalo (kunye nokuguqulwa kwangoku) kwisiphaluka esitshintshisayo.Ukuba ixesha lokusebenza kwesiphazamiso alilunganga ngokubhekiselele kwi-AC-voltage waveform (xa i-arc icinyiwe kodwa abafowunelwa basahamba kwaye i-ionization ayikachithwa kwisiphazamisi), i-voltage inokugqithisa i-gap's withstand voltage. ukutshisa i-arc, kubangele imisinga edlulayo ngokukhawuleza.Kuyo nayiphi na imeko, i-oscillation yaziswa kwisistim enokuthi ibangele ukubaluleka kombane ongaphezulu.Abavelisi be-vacuum-interrupter bajongana nale nkxalabo ngokukhetha izixhobo zoqhagamshelwano kunye noyilo lokunciphisa ukunqunyulwa kwangoku.Ukukhusela izixhobo ukusuka kumbane ongaphezulu, iigiya zokutshitsha zevacuum zihlala zibandakanya izibambi zotyando.
