Bambanci tsakanin MCB da RCCB

Mai watsewar kewayawa: na iya kunnawa, ɗauka da karya na yanzu a ƙarƙashin yanayin kewaye na yau da kullun, Hakanan ana iya kunna shi a ƙarƙashin ƙayyadaddun yanayin da'irar da ba na al'ada ba, ɗaukar wani takamaiman lokaci kuma ya karya halin yanzu na injin injin.

Micro Circuit Breaker, wanda ake magana da shi a matsayin MCB (Micro Circuit Breaker), shine mafi yawan amfani da na'urorin lantarki na kariya ta ƙarshe wajen gina na'urorin rarraba tasha.Ana amfani da shi don gajeren zangon lokaci-ɗaya da matakai uku, nauyi mai yawa da kariya ta wuce gona da iri a ƙasa 125A, gami da nau'ikan nau'ikan 1P guda-pole guda huɗu, igiya biyu 2P, 3P mai ƙarfi uku da 4P mai ƙarfi huɗu.

Na'ura mai kashewa ta ƙunshi tsarin aiki, lambar sadarwa, na'urar kariya (na'urorin saki iri-iri), tsarin kashe baka, da sauransu. Ana sarrafa babbar hanyar sadarwa da hannu ko kuma an rufe ta ta hanyar lantarki.Bayan an rufe babban lamba, tsarin tafiya kyauta yana kulle babban lamba a wurin rufewa.Nada na overcurrent saki da thermal kashi na thermal saki suna da alaka da babban da'irar a jere, da kuma nada na undervoltage saki yana da alaka da wutar lantarki a layi daya.Lokacin da da'irar ta auku gajeriyar kewayawa ko nauyi mai tsanani, armmature na na'urar balaguron balaguro yana zana, yana sa tsarin tafiya kyauta yayi aiki, kuma babban lamba yana cire haɗin babban da'irar.Lokacin da da'irar ta yi yawa, ɓangaren zafin na'urar tafiya ta thermal yana zafi sama don lanƙwasa takardar bimetal da tura hanyar tafiya kyauta don aiki.Lokacin da kewayawa ke ƙarƙashin ƙarfin lantarki, ana sakin ƙwanƙwasa na mai sakin wutar lantarki.Hakanan yana ba da damar tsarin tafiya kyauta yayi aiki.

Ragowar da'ira na yanzu: Maɓalli wanda ke aiki ta atomatik lokacin da ragowar halin yanzu a kewayen ya wuce ƙimar da aka saita.Nau'in da aka saba amfani da shi na leakage da'ira ya kasu kashi biyu: Nau'in wutar lantarki da na yanzu, kuma nau'in na yanzu ya kasu zuwa nau'in lantarki da nau'in lantarki.Ana amfani da magudanar da'ira don hana girgiza kai, kuma yakamata a zaɓa bisa ga buƙatun daban-daban na lamba kai tsaye da kariya ta kai tsaye.

Zaɓi bisa ga manufar amfani da wurin da kayan lantarki yake

1) Kariya daga hulɗar kai tsaye tare da girgiza wutar lantarki

Saboda cutar da kai tsaye girgiza lantarki girgiza ne in mun gwada da girma, sakamakon yana da tsanani, don haka za a zabi wani yayyo circuit breaker tare da babban ji na ƙwarai, don wutar lantarki kayan aikin, mobile lantarki kayan aiki da kuma wucin gadi Lines, ya kamata a shigar a cikin madauki aiki halin yanzu na 30mA. lokacin aiki tsakanin 0.1s leakage circuit breaker.Don gidajen zama tare da ƙarin kayan aikin gida, yana da kyau a shigar da shi bayan shigar da mitar makamashi na gida.

Idan da zarar girgiza wutar lantarki ta yi sauƙi don haifar da lahani na biyu (kamar aiki a tsayi), ya kamata a shigar da na'urar kashe wutar lantarki mai ƙarfin aiki na 15mA da lokacin aiki a cikin Amurka a cikin madauki.Don kayan aikin likitancin lantarki a asibitoci, ya kamata a shigar da na'urorin da'ira mai ɗigo tare da aiki na yanzu na 6mA da lokacin aiki a cikin Amurka.

2) Kariyar lamba ta kai tsaye

Mutuwar wutar lantarki kai tsaye a wurare daban-daban na iya haifar da lahani daban-daban ga mutum, don haka ya kamata a shigar da na'urorin da'ira daban-daban a wurare daban-daban.Ana buƙatar yin amfani da na'urorin da'ira mai ɗigo tare da ingantacciyar hankali don wuraren da girgizar lantarki ta fi cutarwa.A wuraren da aka jika fiye da busassun wuraren haɗarin wutar lantarki ya fi girma, gabaɗaya yakamata a shigar da halin yanzu mai aiki na 15-30mA, lokacin aiki a cikin 0.1s yayyo kewayawa.Don kayan lantarki a cikin ruwa, ya kamata a shigar da aikin.Leakage circuit breaker tare da na yanzu na 6-l0mA da lokacin aiki a cikin Amurka.Don kayan aikin lantarki inda mai aiki dole ne ya tsaya akan wani ƙarfe ko a cikin kwandon ƙarfe, muddin ƙarfin lantarki ya fi 24V, ya kamata a shigar da na'urar da'ira mai ƙyalli mai aiki ƙasa da 15mA da lokacin aiki a cikin Amurka.Don ƙayyadaddun kayan aikin lantarki tare da ƙarfin lantarki na 220V ko 380V, lokacin da juriya na ƙasa na gidaje ya kasance ƙasa da 500fZ, injin guda ɗaya na iya shigar da mai jujjuyawar kewayawa tare da halin yanzu na 30mA da lokacin aiki na 0.19.Don manyan kayan lantarki tare da ƙimar halin yanzu fiye da 100A ko da'ira mai samar da wutar lantarki tare da na'urorin lantarki da yawa, ana iya shigar da na'urar tashe-tashen hankula mai aiki na 50-100mA.Lokacin da juriya na ƙasa na kayan lantarki ya kasance ƙasa da 1000, ana iya shigar da na'urar keɓaɓɓiyar kewayawa tare da aiki na yanzu na 200-500mA.
