Misalai shi ne Vacuum Switchgear?
Me kuke so kuwa Vacuum Switchgear?
Ta harsuna Vacuum Switchgear
Vacuum switchgear ta harsuna wata na'urar da ake amfani da vacuum a matsayin yanayi da ake yi a kan tashar mutane don bayyana masu sauki, wanda yake ba da inganci da kuma babban gaba-gaba.
Koziyar Inganci
A kan tushen tashar mutanen da ke faruwa, vacuum ya ba da koziyar inganci mai tsawon da takwas. A kan tushen tashar mutanen da ke faruwa, vacuum ya ba da koziyar inganci mai tsawon da takwas. Idan a haɗa shi da air, vacuum ya ba da koziyar inganci mai tsawon da takwas. Idan a haɗa shi da SF6 gas a bar, vacuum ya ba da koziyar inganci mai tsawon da takwas. Saboda haka, tushen tashar mutanen da ke faruwa a cikin vacuum circuit breaker ya zama da kyau saboda koziyar inganci mai tsawon da takwas. A cikin wannan tushen tashar mutanen da ke faruwa, ana iya bayyana masu sauki da dalilai koziyar inganci mai tsawon da takwas. Tushen tashar mutanen da ke faruwa a cikin vacuum circuit breaker yana da kyau saboda koziyar inganci mai tsawon da takwas. Wannan yana ba da damar aiki da ke faruwa ga vacuum switchgear don bayyana masu sauki.
Yawan Inganci Mai Tsawon Da Takwas
Yawan inganci mai tsawon da takwas da ake samu a kan tashar mutanen da ke faruwa a cikin vacuum yana da tsawon da takwas mai tsawon da takwas idan a haɗa shi da oil da kuma SF6 gas. Wannan yawan inganci mai tsawon da takwas yana da damar aiki da ke faruwa saboda lokacin da ake koyar tashar mutanen da ke faruwa da kuma tushen tashar mutanen da ke faruwa. Wannan yana ba da damar aiki da ke faruwa saboda lokacin da ake koyar tashar mutanen da ke faruwa da kuma tushen tashar mutanen da ke faruwa. Saboda haka, vacuum switchgear yana da muhimmanci saboda abin da ake buƙaci da tashar mutanen da ke faruwa. Duk da haka, a cikin vacuum circuit breaker, yawan inganci mai tsawon da takwas da ake buƙaci da tashar mutanen da ke faruwa yana da tsawon da takwas idan a haɗa shi da air circuit breaker da kuma oil circuit breaker.
Muhimmanci Mechanism Na Koyar Tashar Mutanen Da Ke Faruwa
A cikin SF6, oil da air circuit breaker, har zuwa tashar mutanen da ke faruwa yana da nasara mai tsawon da takwas saboda medium mai tsawon da takwas. Amma a cikin vacuum switchgear, ba a nan medium, kuma har zuwa tashar mutanen da ke faruwa yana da tsawon da takwas saboda tushen tashar mutanen da ke faruwa. Saboda haka, energy da ake buƙaci don koyar tashar mutanen da ke faruwa yana da tsawon da takwas. Wannan yana ba da damar aiki da ke faruwa saboda mechanism na spring-spring mai tsawon da takwas. Ba a nan hydraulic da pneumatic mechanism. Mechanism mai tsawon da takwas yana ba da damar aiki da ke faruwa saboda mechanical life mai tsawon da takwas.
Rapid Arc Quenching
Idan ake koyar tashar mutanen da ke faruwa a cikin tushen tashar mutanen da ke faruwa, metal vapour yana faruwa a kan tashar mutanen da ke faruwa, kuma wannan metal vapour yana ba da hanyar da electric current yana ci gaba har zuwa current zero. Wannan al'amari ta harsuna vacuum arc. Wannan arc yana rasa ne a cikin lokacin da current zero, kuma conductive metal vapor yana zama da kyau a cikin microseconds. Ana sani cewa faɗa 1% daga vapor yana zama da kyau a kan side wall na arc chamber, kuma 99% daga vapor yana zama da kyau a kan contact surface inda yake faruwa.
Daga cikin al'amuran da aka bincike, ita ce da ake sani cewa koziyar inganci na vacuum switchgear yana zama da kyau kuma abin da ake buƙaci da tashar mutanen da ke faruwa yana da tsawon da takwas.
Idan current yana da 10 KA, arc a cikin vacuum switchgear yana zama diffused, yana zama da kyau a cikin contact surface. Idan current yana da 10 KA, arc yana zama da kyau a kan center na contact surface saboda magnetic field, wanda yake buƙaci da overheat. Wannan matsala yana iya zaɓe ta hanyar designing contact surfaces don bayyana arc don zo a cikin surface area. Manufactures suna amfani da designs mai tsawon da takwas don zaɓe wannan, domin bayyana minimal da kuma uniform contact erosion.
