Dulmar guud-mariyaha Vacuum circuit breaker

Horudhaca wareegga wareegga Vacuum

"Vacuum Circuit Breaker" ayaa magaceeda loo helay sababtoo ah bakhtiyaasheeda dhexdhexaadka ah iyo dhexdhexaadiyaha dahaarka ee farqiga xiriirka ka dib daminta arc labaduba waa faaruq sare;waxay leedahay faa'iidooyinka cabbirka yar yar, miisaanka fudud, ku habboon qalliinka soo noqnoqda, iyo dayactir la'aan bakhtiinta arc.Codsiyada ku jira shabakada korontadu waa kuwo baahsan.Xadhkaha goosha sare ee vacuum circuit waa qalab qaybinta korantada gudaha gudaha 3 ～ 10kV, 50Hz 3-waji AC ah.Waxaa loo isticmaali karaa ilaalinta iyo xakamaynta qalabka korontada ee warshadaha iyo shirkadaha macdanta, warshadaha korontada, iyo substations.Si loo dayactiro iyo isticmaalka joogtada ah, wareegtada wareegga waxaa lagu habeyn karaa golaha dhexe, golaha laba-lakabka ah iyo golaha go'an ee xakamaynta iyo ilaalinta qalabka korantada ee sare.

Taariikhda Vacuum circuit breaker

Sannadkii 1893-kii, Rittenhouse oo ku taal Maraykanka ayaa soo jeedisay vacuum dhex-geliye leh qaab-dhismeed fudud oo ay heshay rukhsad naqshadaysan.Sannadkii 1920kii, Shirkadda Foga ee Iswiidhishka ayaa samaysay beddelkii ugu horreeyay ee faakuumka.Natiijooyinka cilmi-baarista ee la daabacay 1926 iyo kuwo kale ayaa sidoo kale muujinaya suurtagalnimada in hadda la jebiyo meel bannaan.Si kastaba ha ahaatee, iyada oo ay ugu wacan tahay awoodda jebinta yar iyo xaddidaadda heerka horumarinta tignoolajiyada faakuumka iyo walxaha faakuumka, looma adeegsan isticmaalka dhabta ah.Horumarinta tignoolajiyada faakuumka, 1950-meeyadii, Maraykanku waxa uu sameeyay dufcaddii ugu horreysay ee furayaasha vacuum ku habboon in la gooyo bangiyada capacitor-ka iyo shuruudaha kale ee gaarka ah.Xakamaynta jebinta ayaa weli ku jirta heerka 4 kun oo amps.Horumarka laga sameeyay tignoolajiyada dhalada walxaha faakuumka iyo horumarka laga gaadhay cilmi baadhista qaab dhismeedka xidhiidhka furaha furaha, 1961kii, waxa bilaabmay soo saarida jejebiyayaasha wareegyada faakuumka oo leh danab dhan 15 kV iyo wakhtiga jaban ee 12.5kA.Sannadkii 1966-kii, 15 kV, 26 kA, iyo 31.5 kA vacuum circuit breakers ayaa tijaabo la soo saaray, sidaas darteed fakuumka wareegga wareegga wuxuu galay nidaam koronto oo sarreeya, awood weyn leh.Bartamihii 1980-aadkii, awoodda jebinta wareegyada wareegyada faakuumku waxay gaadhay 100 kA.Shiinuhu waxa uu bilaabay in uu samaysto furayaasha faakuumka sanadii 1958kii iyo jabinta awoodda 1.5.Qian'an saddex-waji furaha furaha1969kii, Huaguang Electron Tube Factory iyo Xi'an High Voltage Apparatus Research Institute waxay soo saareen 10 kV, 2 kA hal waji oo degdeg ah.Tan iyo 1970-meeyadii, Shiinuhu waxa uu awooday in uu si madax-bannaan u horumariyo oo uu u soo saaro furayaasha faakuumka ee tilmaamo kala duwan.

Qeexida jebinta wareegga Vacuum

Xakamaynta wareegyada vacuum waxay badanaa u qaybsamaan heerar koronto oo badan.Nooca danab yar ayaa guud ahaan loo isticmaalaa isticmaalka koronto ee aan qarxin.Sida dhuxusha iyo wixii la mid ah.

Hadda la qiimeeyay waxa uu gaadhay 5000A, hadda jabay waxa uu gaadhay heer ka wanaagsan 50kA, waxana uu gaadhay danab dhan 35kV.

Kahor 1980-meeyadii, vacuum circuit breakers waxay ku jireen marxaladii hore ee horumarka, waxayna si joogto ah u sahamiyeen farsamada.Suurtagal ma ahayn in la sameeyo heerar farsamo.Ma ahayn ilaa 1985 in heerarka wax soo saarka la sameeyay.
