Inductance gabatarwa

1. Reactance na nada na DC gudun ba da sanda yana da girma kuma na yanzu yana ƙarami. Idan aka ce ba zai lalace ba lokacin da aka haɗa shi da alternating current, za a sake shi lokacin da ya dace. Duk da haka, reactance na nada na AC relay kadan ne, kuma na yanzu yana da girma. Haɗin DC zai lalata nada.

2. Za a yi wani gajeren kewaye zobe a kan baƙin ƙarfe core na AC contactor, amma ba DC contactor. Diamita na waya na nada DC siriri ne, saboda halin yanzu yana daidai da U/R, kuma baya canzawa. Diamita na waya na coil AC yana da kauri, saboda coil ɗin yana da inductance, kuma halin yanzu yana canzawa sosai kafin da bayan an jawo hannun armature. Idan armature ya makale kuma bai ja hankali ba, zai ƙone nada. Bakin ƙarfe na AC nada dole ne ya yi amfani da takardar ƙarfe na silicon, kuma ɗigon ƙarfe na DC na iya amfani da katangar ƙarfe gabaɗaya.

3. Jan hankali da halin yanzu na AC electromagnet suna canzawa, duka biyun sun fi girma a farkon abin jan hankali, amma ƙarami bayan jan hankali. Koyaya, jan hankali da halin yanzu na electromagnet na DC ya kasance baya canzawa yayin duk aikin jawowa da riƙewa.

4. AC coils ba a daraja, yayin da DC coils yawanci polarized. Ka'idodin aikin su iri ɗaya ne. Duk suna haifar da filin maganadisu a cikin nada don haifar da aiki na gaba. Bambanci shi ne cewa coils AC suna haifar da filin maganadisu mai canzawa, wanda ƙarfin lantarki da na yanzu ke tasiri sosai, yayin da DC coils sun fi kwanciyar hankali kuma suna da babban yanayin tsaro, wanda ya fi dacewa da yanayin aiki nan take.

A zahiri, na'urar caji mara igiyar waya tana da inductance mafi girma da ƙarami inductance yoyo, kuma rayuwar sabis ɗin ta ya fi ƙarfin inductance na gaba ɗaya. Na yi imani kowa ya san cewa watanni shida shine lokacin inductance, amma cajin caji mara waya ya dogara da tsarin masana'antu da yanayin ajiya. Cajin caji mara waya ta wuce gwajin maganin oxidation da gwajin feshin gishiri kafin barin masana'anta don tabbatar da ingantaccen weldability na samfurin. Ana rufe kowace ƙaramar jakar marufi da akwati na ciki kuma an sanya su tare da na'urar bushewa, don haka za'a iya tsawaita lokacin ajiyar zuwa watanni takwas. Bugu da ƙari, an yi amfani da kayan ferrite a babban zafin jiki fiye da digiri 1000, don haka yana da ƙarfin gaske kuma ana iya tabbatar da shi har abada.
