Ka'idoji na asali:
Sauyawa da kayan sarrafawa shine lokaci na asali, wanda ya haɗa da sauyawa da haɗuwa tare da kulawar taimako, ganowa, kariya da na'urorin daidaitawa.Hakanan ya haɗa da haɗin kayan lantarki da na'urori tare da wayoyi na ciki, na'urori masu taimako, gidaje da sassa masu goyan baya.Ana amfani da Switchgear don samar da wutar lantarki, watsawa, rarrabawa da ayyukan canza wutar lantarki.Ana amfani da kayan sarrafawa don aikin sarrafawa na na'urar amfani da wutar lantarki.
Sauyawa da kayan sarrafawa sun haɗa da mahimman ra'ayoyi guda uku:
• kaɗaici
Don aminci, yanke wutar lantarki ko raba na'urar ko sashin bas daga kowace wutar lantarki don samar da keɓantaccen sashe na na'urar (misali, lokacin da ya zama dole don yin aiki akan na'urar kai tsaye).Kamar maɓalli na kaya, mai cire haɗin, mai watsewar kewayawa tare da aikin keɓewa, da sauransu.
sarrafawa (a kashe)
Don manufar aiki da kiyayewa, haɗi ko cire haɗin ƙarƙashin yanayin aiki na yau da kullun.Irin su contactor da mai kunna mota, sauyawa, sauyawar gaggawa, da sauransu.
• kariya
Don hana mummunan yanayi na igiyoyi, kayan aiki da ma'aikata, kamar nauyi mai yawa, gajeriyar kewayawa da kuskuren ƙasa, ana amfani da hanyar cire haɗin kuskuren halin yanzu don ware laifin.Kamar su: mai watsewar kewayawa, rukunin fuse, relay mai kariya da haɗin kayan sarrafawa, da sauransu.
Sauya kayan aiki
1. Fushi:
An fi amfani dashi azaman kariyar gajeriyar kewayawa.Lokacin da da'irar ta yi gajeriyar kewayawa ko kuma tayi nauyi sosai, za ta haɗa kai tsaye ta yanke da'irar don kariya.An kasu kashi na gaba ɗaya da nau'in na musamman na semiconductor.
2. Load switch/ fuse switch (switch fuse group):
Na'urori masu sauyawa na injina waɗanda zasu iya haɗawa, ɗauka da cire haɗin na yau da kullun na yau da kullun da ɗaukar halin yanzu a ƙarƙashin yanayi mara kyau (waɗannan maɓalli ba za su iya cire haɗin gajeriyar kewayawar halin yanzu ba)
3. Firam ɗin kewayawa (ACB):
Ƙididdigar halin yanzu shine 6300A;Ƙimar wutar lantarki zuwa 1000V;Ƙarfafa ƙarfin har zuwa 150ka;Sakin kariya tare da fasahar microprocessor.
4. Molded case circuit breaker (MCCB):
Ƙididdigar halin yanzu shine 3200A;Ƙimar ƙarfin lantarki zuwa 690V;Karɓar ƙarfin har zuwa 200kA;Sakin kariyar yana ɗaukar fasahar wutar lantarki ta thermal ko fasahar microprocessor.
5. Karamin na'ura mai karyawa (MCB)
Ƙididdigar halin yanzu bai wuce 125A ba;Ƙimar ƙarfin lantarki zuwa 690V;Karya iya aiki har zuwa 50kA
6. Thermal electromagnetic kariya saki da aka soma
Ragowar halin yanzu (leakage) mai watsewar kewayawa (rccb/rcbo) RCBO gabaɗaya ya ƙunshi MCB da sauran na'urorin haɗi na yanzu.Karamar mai watsewar da'ira mai saura kariya ta halin yanzu ana kiranta RCCB, sauran na'urar kariya ta yanzu ana kiranta RCD.
