Izidingo Zokusebenza kanye Nokubunjwa Kwe-Transformer Core Laminations

Ngesikhathi sokusebenza okuvamile kwe-transformer, kunenkambu kagesi ekhona phakathi kwama-winding anamandla kanye nethangi, enomongo nezinye izakhi zensimbi ezitholakala ngaphakathi kwalo mkhakha. Ngenxa yokungalingani kokusabalalisa amandla namandla enkambu ahlukahlukene, uma ingqikithi ingasekelwenga ngokuthembekile, izenzakalo zokushaja nokukhipha zizokwenzeka. Lokhu kungonakalisa ukufakwa okuqinile futhi kunciphise amandla e-dielectric kawoyela; ngakho-ke, umgogodla kufanele ube nesisekelo esithembekile sephuzu elilodwa.

I-transformer core laminations yenziwe ngamashidi ensimbi ye-silicon. Ukuze unciphise ama-eddy currents, kunezinga elithile lokumelana nokufakwa phakathi kwamashidi (ngokuvamile ukusuka kuma-ohm ambalwa kuya kumashumi ambalwa ama-ohms). Ngenxa yokuthi i-inter-sheet capacitance inkulu ngokwedlulele, ingabhekwa njengendlela yokuqondisa endaweni kagesi eshintshanayo. Ngakho-ke, ukugxilisa umgogodla endaweni eyodwa kwanele ukubopha amandla awo wonke ama-laminations ayisitaki ukuze kube namandla angaphansi.

Uma i-transformer core noma izingxenye zayo zensimbi zisekelwe kumaphuzu amabili noma ngaphezulu, i-loop evaliwe izokwakhiwa phakathi kwamaphoyinti aphansi. Le loop ixhumanisa ingxenye ye-flux kazibuthe, idala amandla e-electromotive (EMF) futhi idale umsinga ojikelezayo. Lokhu kuholela ekushiseni okweqile kwendawo futhi kungashisa ngisho nomnyombo.

Umhlabathi onephuzu elilodwa ukuphela kwesimo sosisekelo esamukelekayo nesivamile somgogodla we-transformer. Ngamanye amazwi, ingqikithi kufanele isekelwe phansi, futhi kufanele isekelwe endaweni eyodwa ncamashi.

Kumelwe kufakwe umthofu ohlukile wesisekelo esakhiweni sokubopha ijoka. Uma ingqikithi ithinta ngephutha isakhiwo sokubopha esingaphezulu, okubangela iphutha lokusekela lamaphuzu amaningi, iphutha lamanje lizozungeza kuphela ngaphakathi kwesakhiwo sokubopha. Awekho amandla azogeleza emthonjeni oyisisekelo oyisisekelo, ongadukisa abasebenzi ukuthi bakholelwe ukuthi alikho iphutha. Ngokufaka lo mthofu ohlukile, iluphu evaliwe yenziwa ngemikhondo emibili yangaphandle yangaphandle kungakhathaliseki ukuthi ingqikithi ithintanaphi nesakhiwo sokubopha, okuvumela amandla aphansi ukuthi atholwe ngokunembile ngaphandle.
