Tarihin Vacuum circuit breaker
A cikin 1893, Rittenhouse a Amurka ya ba da shawarar mai katsewa tare da tsari mai sauƙi kuma ya sami takardar izinin ƙira.A cikin 1920, Kamfanin Foga na Yaren mutanen Sweden ya yi canji na farko.Sakamakon bincike da aka buga a 1926 da wasu kuma sun nuna yuwuwar karya halin yanzu a cikin sarari.Duk da haka, saboda ƙananan ƙarfin karyewa da ƙayyadaddun matakan haɓaka fasahar fasaha da kayan injin, ba a yi amfani da shi a aikace ba.Tare da haɓaka fasahar vacuum, a cikin 1950s, Amurka kawai ta yi kashin farko na vacuum switches wanda ya dace da yanke bankunan capacitor da sauran buƙatu na musamman.Karɓar halin yanzu yana kan matakin 4 dubu amps.Saboda ci gaban fasahar goge kayan injin da kuma ci gaba a cikin binciken tsarin tuntuɓar injin, a cikin 1961, an fara samar da injin da'ira mai ƙarfin lantarki na 15 kV da 12.5 kA mai karye.A cikin 1966, 15 kV, 26 kA, da 31.5 kA vacuum circuit breaks an yi gwaji-sarrafa, ta yadda injin da'irar ya shiga cikin tsarin wutar lantarki mai girma mai girma.A tsakiyar shekarun 1980, karfin karyawar injin da'ira ya kai 100 kA.A shekarar 1958, kasar Sin ta fara kera na'urorin maye gurbi a shekarar 1960. A shekarar 1960, jami'ar Xi'an Jiaotong da masana'antar gyaran fuska ta Xi'an sun hada gwiwa tare da samar da kashin farko na na'ura mai karfin 6.7kV tare da karya karfin 600 A. Bayan haka, an mai da su zuwa kV10. da ƙarfin karya na 1.5.Qian'an mara motsin lokaci uku.A shekarar 1969, kamfanin Huaguang Electron Tube Factory da Xi'an High Voltage Apparatus Research Institute sun samar da saurin injin injin mai karfin kilo 10 da 2 kA.Tun daga shekarun 1970s, kasar Sin ta sami damar yin gyare-gyare da kanta bisa kanta da kuma samar da na'urorin maye na musamman.

Yawanci ana kasuwar injin da'ira zuwa matakan ƙarfin lantarki da yawa.Ana amfani da nau'in ƙarancin wutar lantarki gabaɗaya don amfani da wutar lantarki mai hana fashewa.Kamar ma'adinan kwal da sauransu.
Ƙididdigar halin yanzu ya kai 5000A, raguwar halin yanzu ya kai matsayi mafi kyau na 50kA, kuma ya haɓaka zuwa ƙarfin lantarki na 35kV.
Kafin shekarun 1980, masu ba da wutar lantarki sun kasance a matakin farko na ci gaba, kuma suna binciken fasaha akai-akai.Ba zai yiwu a tsara matakan fasaha ba.Sai a shekarar 1985 aka yi ka'idojin samfur masu dacewa.
