IZINHLOBO ZEZISHINTSHO ZOKUPHULWA KOMTHWALO

Iswishi yomthwalo ene-voltage ephezulu isetshenziselwa ukuphula ugesi womthwalo (kufaka phakathi ugesi wokulayisha ojwayelekile) osebenza, futhi inekhono elithile lokulungisa ugesi we-short-circuit we-photosynthesis kanye nokuqina kokushisa. Ivame ukusetshenziswa kanye nama-fuse ohlelweni lwamandla. Iswishi yomthwalo isetshenziselwa ukulawula nokuvikela ugesi wokulayisha, kanti i-fuse isetshenziselwa ukuvikela ugesi wokulayisha wodwa.
Ngenxa yokuthi iswishi yomthwalo idinga kuphela ukuphula ugesi omncane womthwalo, imishini yayo yokucisha i-arc ilula kakhulu kuneye-circuit breaker. Ngokwesimiso sokucisha i-arc kanye nemidiya ehlukene, iziswishi zomthwalo zingahlukaniswa ngezigaba ezilandelayo:
1. Sebenzisa amandla e-arc ukwenza izinto zokukhiqiza igesi eqinile zikhiqize igesi, bese ushaya i-arc ukuze imise inkinobho yokulayisha igesi eqinile.
2. Iswishi yomthwalo womoya ocindezelwe esebenzisa umoya wokucindezela we-piston ukukhiqiza umphumela wokushaya komoya ukwenza i-arc imiswe, igesi ingaba umoya noma igesi ye-hexafluoride yesulfure.
3. Iswishi yomthwalo ecwiliswe ku-oyela iyiswishi yomthwalo ecwiliswe ku-oyela esebenzisa amandla e-arc ku-oyela ukwenza uwoyela uphele futhi ubole ukuze kukhiqizwe igesi, ukuze i-arc iphole futhi imiswe.
4. Iswishi yomthwalo we-vacuum elenga i-arc ku-vacuum ifana ngesakhiwo ne-vacuum circuit breaker, kodwa izinto zokuxhumana zihlukile.
5. Iswishi yomthwalo we-hexafluoride yesulfure ecima i-arc kugesi ye-hexafluoride yesulfure.
