Isiphazamisi sevacuum, ekwaziwa ngokuba yityhubhu yokutshintsha ivacuum, lelona candelo lingundoqo lokutshintsha kwamandla ombane aphezulu.Umsebenzi ophambili we-vacuum interrupter kukwenza isekethe ephakathi kunye nephezulu yombane inqumle unikezelo lwamandla egumbi lokucima i-arc ye-arc yokucima iqokobhe le-ceramic ngokusebenzisa i-insulation egqwesileyo ye-vacuum ngaphakathi kwityhubhu, enokucima ngokukhawuleza i-arc kunye nokucinezela okwangoku. , ukwenzela ukuba ugweme iingozi kunye neengozi.Isiphazamisi se-vacuum sahlulwe kusetyenziso lwesiphazamisi kunye nokutshintsha komthwalo.I-interrupter ye-circuit breaker isetyenziswa kakhulu kwi-substation kunye nezibonelelo zegridi yamandla kwisebe lamandla ombane.Ukutshintsha komthwalo kusetyenziselwa ikakhulu abasebenzisi beterminal begridi yamandla.
Ukusetyenziswa kwe-vacuum yokutshintsha imisinga yombane kwakhuthazwa kukuqwalasela ukuba isithuba sesentimitha enye kwi-tube ye-X-ray inokumelana namashumi amawaka e-volts.Nangona ezinye izixhobo zokutshintsha ivacuum zazinelungelo elilodwa lomenzi ngenkulungwane ye-19, zazingekho kurhwebo.Kwi-1926, iqela elikhokelwa yiRoyal Sorensen kwi-California Institute of Technology liphanda ukutshintshwa kwe-vacuum kunye nokuvavanya izixhobo ezininzi;Imiba engundoqo yophazamiseko lwe-arc kwindawo engenanto iphandwe.USorenson ubonise iziphumo kwintlanganiso ye-AIEE ngaloo nyaka, kwaye waxela kwangaphambili ukusetyenziswa korhwebo.Ngomnyaka we-1927, uGeneral Electric wathenga amalungelo obunikazi kwaye waqala uphuhliso lwezorhwebo.I-Great Depression kunye nophuhliso lwe-oyile-ezaliswe yi-switchgear yabangela ukuba inkampani inciphise umsebenzi wophuhliso, kwaye umsebenzi omncinci obalulekileyo wezorhwebo wenziwa kwi-vacuum power switchgear de kwaba ngo-1950.
1. Indlela yokusebenza incinci, umthamo wonke uncinci, kwaye ubunzima bulula.
2. Amandla okulawula amancinci, kwaye ingxolo yesenzo incinci ngexesha lokusebenza kokutshintsha.
3. Indawo yokucima i-arc okanye i-insulating medium ayisebenzisi ioli, ngoko akukho ngozi yomlilo kunye nokuqhuma.
4. Inxalenye yoqhagamshelwano yisakhiwo esitywinwe ngokupheleleyo, esingayi kunciphisa ukusebenza kwayo ngenxa yempembelelo yomswakama, uthuli, iigesi eziyingozi, njl., kwaye isebenza ngokuthembekileyo ngokuzinza kokusebenza.
5. Emva kokuba i-vacuum circuit breaker ivuliwe kwaye iphukile, i-medium phakathi kwe-fractures ibuyisela ngokukhawuleza, kwaye i-medium ayifuni ukutshintshwa.
