Vacuum interrupter ye inflatable cabinet (132A)
Tsanangudzo pfupi yechigadzirwa:
Muna 1926, boka rinotungamirirwa naRoyal Sorensen kuCalifornia Institute of Technology rakatsvaga vacuum switching uye yakaedza michina yakawanda;zvakakosha zve arc kukanganiswa mune vacuum zvakaongororwa.Sorenson akapa mhedzisiro pamusangano weAIEE gore iroro, uye akafanotaura kushandiswa kwekutengesa kwekuchinja.Muna 1927, General Electric akatenga kodzero dzepa patent ndokutanga kusimudzira kutengeserana.The Great Depression uye kuvandudzwa kwemafuta-akazadzwa switchgear kwakakonzera kambani kudzikisa basa rekusimudzira, uye basa diki rinokosha rekutengesa rakaitwa pavacuum power switchgear kusvika kuma1950s.
Muna 1956, H. Cross yakashandura high-frequency-circuit vacuum switch uye yakagadzira vacuum switch ine chiyero che 15 kV pa 200 A. Makore mashanu gare gare, Thomas H. Lee kuGeneral Electric akagadzira yekutanga vacuum circuit breakers ine yakarongwa. voltage ye 15 kV panguva pfupi-circuit breaking currents ye12.5 kA.Muna 1966, zvishandiso zvakagadziridzwa zvine rated voltage ye15 kV uye pfupi-circuit breaking currents ye25 uye 31.5 kA.Mushure memakore ekuma1970, vacuum switch dzakatanga kutsiva madiki-oiri switch mune yepakati-voltage switchgear.mukutanga kwema1980, SF6 switch uye mabreaker akatsiviwawo zvishoma nezvishoma ne vacuum tekinoroji mune yepakati-voltage application.
Kubva muna 2018, vacuum circuit breaker yakanga yasvika 145 kV uye breaking current yakanga yasvika 200 kA.

Iwo macontacts anotakura dunhu razvino kana akavharwa, achigadzira materminals earc kana akavhurwa.Iwo akagadzirwa nemhando dzakasiyana-siyana, zvichienderana nekushandiswa kwevacuum interrupter uye dhizaini yehupenyu hurefu hwekusangana, kukurumidza kudzoreredza kwevoltage inomira rating, uye kutonga kwekuwedzeredza nekuda kwekutema kwazvino.
Iyo yekunze inoshanda sisitimu inotyaira iyo inofamba inobata, iyo inovhura nekuvhara yakabatana dunhu.Iyo vacuum interrupter inosanganisira gidhi sleeve yekudzora inofamba kubata uye kudzivirira mabhero ekuvharira kubva pakumonyoroka, izvo zvaizopfupisa hupenyu hwayo zvakanyanya.
