Kuyambitsa kwa Vacuum circuit breaker

"Vacuum Circuit Breaker" imatchedwa dzina lake chifukwa chozimitsira moto komanso chotchingira cholumikizirana pambuyo pa kuzimitsa kwa arc ndi vacuum yayikulu;ili ndi ubwino waung'ono, kulemera kochepa, koyenera kugwira ntchito pafupipafupi, ndipo palibe kukonza kwa arc kuzimitsa.Ntchito mu gridi yamagetsi ndizofala kwambiri.High voltage vacuum circuit breaker ndi chipangizo chogawa magetsi m'nyumba mu 3 ～ 10kV, 50Hz magawo atatu a AC system.Itha kugwiritsidwa ntchito poteteza ndi kuwongolera zida zamagetsi m'mabizinesi am'mafakitale ndi migodi, mafakitale amagetsi, ndi malo ocheperako.Pofuna kukonza komanso kugwiritsidwa ntchito pafupipafupi, chophwanyira dera chimatha kukhazikitsidwa pakati pa kabati, kabati yokhala ndi magawo awiri ndi kabati yokhazikika yowongolera ndi kuteteza zida zamagetsi zamagetsi.

Mbiri ya Vacuum circuit breaker

Mu 1893, a Rittenhouse ku United States anakonza zoti pakhale chosokoneza chotchinga ndi chotchinga chosavuta ndikupeza chilolezo chopanga mapangidwe.Mu 1920, Swedish Foga Company inapanga chosinthira choyamba cha vacuum.Zotsatira zafukufuku zomwe zidasindikizidwa mu 1926 ndi ena zikuwonetsanso kuthekera kothyola pompopompo mu vacuum.Komabe, chifukwa cha kuchepa kwazing'ono komanso kuchepa kwa chitukuko cha teknoloji ya vacuum ndi zipangizo za vacuum, sizinagwiritsidwe ntchito.Ndi chitukuko cha ukadaulo wa vacuum, m'zaka za m'ma 1950, United States idangopanga gulu loyamba la ma switch a vacuum oyenera kudula mabanki a capacitor ndi zofunika zina zapadera.Kusweka kwapano kukadali pamlingo wa 4 ma amps.Chifukwa cha kupita patsogolo kwaukadaulo wosungunula zinthu za vacuum komanso kupita patsogolo kwa kafukufuku wa ma switch a vacuum, mu 1961, kupanga ma vacuum circuit breakers okhala ndi voteji ya 15 kV komanso kuphulika kwa 12.5 kA kunayamba.Mu 1966, 15 kV, 26 kA, ndi 31.5 kA zowonongeka zowonongeka zinapangidwa moyesera, kotero kuti chopukutira chamagetsi chinalowa m'dongosolo lamagetsi, lamphamvu kwambiri.M'katikati mwa zaka za m'ma 1980, mphamvu zowonongeka za zowonongeka zowonongeka zinafika 100 kA.China idayamba kupanga masiwichi a vacuum mu 1958. Mu 1960, Xi'an Jiaotong University ndi Xi'an Switch Rectifier Factory pamodzi zinapanga gulu loyamba la ma switch a vacuum 6.7 kV omwe amatha kusweka 600 A. Kenako, adapangidwa kukhala 10 kV ndi kusweka mphamvu 1.5.Qian'an magawo atatu vacuum switch.Mu 1969, Huaguang Electron Tube Factory ndi Xi'an High Voltage Apparatus Research Institute inapanga 10 kV, 2 kA single-phase fast vacuum switch.Kuyambira zaka za m'ma 1970, China yatha kudzipanga yokha ndikupanga ma switch a vacuum amitundu yosiyanasiyana.

Mafotokozedwe a Vacuum circuit breaker

Vacuum circuit breakers nthawi zambiri amagawidwa m'magulu angapo amagetsi.Mtundu wamagetsi otsika nthawi zambiri umagwiritsidwa ntchito pamagetsi osaphulika.Monga migodi ya malasha ndi zina zotero.

Zomwe zidavotera pano zimafika pa 5000A, kusweka kumafika pamlingo wabwinoko wa 50kA, ndipo zakula mpaka voteji ya 35kV.

Zaka za m'ma 1980 zisanafike, oyendetsa magetsi anali mu gawo loyamba la chitukuko, ndipo nthawi zonse ankafufuza zamakono.Sizinali zotheka kupanga miyezo yaukadaulo.Sizinali mpaka 1985 pomwe miyezo yoyenera yazinthu idapangidwa.
