Overview Vacuum circuit breaker

Nhanganyaya yeVacuum circuit breaker

"Vacuum Circuit Breaker" inowana zita rayo nekuti iyo arc yekudzima svikiro uye yepakati yekudzimisa yegeji rekusangana mushure mekudzima arc ese ari akakwira vacuum;ine mabhenefiti ehukuru hudiki, huremu huremu, hwakakodzera kushanda kazhinji, uye hapana kuchengetedza kwekudzima arc.Zvishandiso mumagetsi emagetsi zvakapararira.High voltage vacuum circuit breaker mudziyo wekugovera simba remukati mune 3 ～ 10kV, 50Hz matatu-phase AC system.Inogona kushandiswa kudzivirira uye kutonga kwemidziyo yemagetsi mumaindasitiri uye emigodhi mabhizinesi, zvidyarwa zvemagetsi, uye zviteshi.Nekuchengetedza uye kushandiswa nguva dzose, dunhu rinotyora rinogona kugadziridzwa mukati mekati kabati, kaviri-layer cabinet uye fixed cabinet yekudzora nekudzivirira yakakwirira-voltage magetsi emagetsi.

Nhoroondo yeVacuum circuit breaker

Muna 1893, Rittenhouse muUnited States yakaronga chivhariso chevacuum ine chimiro chakareruka uye yakawana patent yekugadzira.Muna 1920, iyo Swedish Foga Kambani yakaita yekutanga vacuum switch.Mhedzisiro yekutsvagisa yakaburitswa muna 1926 uye vamwe vanoratidzawo mukana wekupwanya ikozvino muvacuum.Nekudaro, nekuda kweiyo diki yekutyora simba uye kudzikiswa kwedanho rekusimudzira tekinoroji yevacuum uye vacuum zvinhu, haina kuiswa mukushandisa.Nekuvandudza tekinoroji yevacuum, muma1950s, United States yakangoita batch yekutanga yevacuum switch yakakodzera kucheka capacitor mabhangi uye zvimwe zvakakosha zvinodiwa.Iko kuputsa ikozvino kuchiri pamwero we4 zviuru amps.Nekuda kwekufambira mberi muvacuum material yekunyungudutsa tekinoroji uye kubudirira mukutsvagisa kwevacuum switch yekubata zvimiro, muna 1961, kugadzirwa kwevacuum circuit breaker ine voltage ye15 kV uye kubuda kwe12.5 kA kwakatanga.Muna 1966, 15 kV, 26 kA, uye 31.5 kA vacuum circuit breakers dzakaedzwa-dzakagadzirwa, kuitira kuti vacuum circuit breaker yakapinda mu-high-voltage, guru-capacity power system.Pakati pemakore ekuma1980, simba rekuputsa kwevacuum circuit breakers rakasvika 100 kA.China yakatanga kugadzira ma switch evacuum muna 1958. Muna 1960, Xi'an Jiaotong University neXi'an Switch Rectifier Factory vakabatana vakagadzira bhechi rekutanga re6.7 kV vacuum switch rine simba rekutyora 600 A. Zvadaro, dzakaitwa 10 kV uye kutyora kugona kwe1.5.Qian'an matatu-phase vacuum switch.Muna 1969, Huaguang Electron Tube Factory uye Xi'an High Voltage Apparatus Research Institute yakagadzira 10 kV, 2 kA single-phase fast vacuum switch.Kubva kuma1970s, China yakakwanisa kuzvimiririra kugadzira uye kugadzira vacuum switch yeakasiyana siyana.

Iyo yakatarwa yeVacuum circuit breaker

Vacuum circuit breakers inowanzo patsanurwa kuita akawanda voltage mazinga.Low voltage mhando inowanzo shandiswa pakuputika-kusapupudza kushandiswa kwemagetsi.Semigodhi yemarasha nezvimwe zvakadaro.

Iyo yakayerwa ikozvino inosvika 5000A, iyo yekutyora inosvika padanho ririnani re50kA, uye yakagadziridzwa kusvika kumagetsi e35kV.

Pamberi pema1980, vacuum circuit breakers vaive muchikamu chekutanga chekusimudzira, uye vaigara vachiongorora tekinoroji.Zvakanga zvisingabviri kugadzira zviyero zvehunyanzvi.Yakanga isiri kutozosvikira 1985 iyo yakakodzera zvigadzirwa zviyero zvakagadzirwa.
