Halayen inductor core hasãrar (yafi ciki har da hysteresis asarar da eddy halin yanzu asarar) yana daya daga cikin mafi muhimmanci Manuniya na ikon kayan, wanda rinjayar kuma ko da kayyade aiki yadda ya dace, zafin jiki tashi da amincin dukan inji.

Inductor core asarar

1. Rashin hawan jini

Lokacin da ainihin abin da ke cikin magnetized, akwai sassa biyu na makamashin da aka aika zuwa filin maganadisu, ɗaya daga cikinsu yana canzawa zuwa makamashi mai yuwuwa, wato, lokacin da aka cire magnetization na waje, za a iya mayar da wutar lantarki zuwa kewaye. , yayin da ɗayan ɓangaren yana cinyewa ta hanyar shawo kan rikici, wanda ake kira asarar hysteresis.

Yankin ɓangaren inuwa na madaidaicin maganadisu yana wakiltar asarar kuzari ta hanyar hysteresis a cikin aikin maganadisu na ainihin maganadisu a cikin sake zagayowar aiki. Ma'aunin da ke shafar yankin asara shine matsakaicin aikin magnetic flux density B, matsakaicin ƙarfin filin magnetic H, remanence Br da ƙarfin tilastawa Hc, wanda a cikin abin da ƙarfin magnetic da ƙarfin filin magnetic ya dogara da yanayin filin lantarki na waje da Mahimman girman girman ainihin, yayin da Br da Hc suka dogara da kaddarorin kayan. Ga kowane lokaci na magnetization na inductor core, wajibi ne a rasa makamashi daidai da yankin da ke kewaye da madauki na hysteresis. mafi girman mitar shine, mafi girman ƙarfin asarar shine, mafi girman girman induction na maganadisu shine, girman wurin da aka rufe shine, mafi girman asarar hysteresis shine.

2. Eddy halin yanzu hasara

Lokacin da aka ƙara ƙarfin wutar lantarki na AC zuwa na'urar maganadisu na maganadisu, motsin motsi yana gudana ta cikin na'urar, kuma duk motsin maganadisu da ke haifar da zumudi na ampere mai zumudi yana wucewa ta cikin ma'aunin maganadisu. Magnetic core kanta madugu ne, kuma duk wani motsin maganadisu da ke kewaye da sashin giciye na maganadisu yana da alaƙa da samar da coil na biyu na juyi guda. Domin juriya na ma'aunin maganadisu ba shi da iyaka, akwai wani juriya a kewayen core, kuma wutar lantarkin da aka haifar yana haifar da halin yanzu, wato eddy current, wanda ke ratsawa ta wannan juriya, yana haifar da hasara, wato asara a halin yanzu.

3. Rarara asara

Ragowar asarar yana faruwa ne ta hanyar tasirin shakatawa na maganadisu ko tasirin maganadisu. Abin da ake kira shakatawa yana nufin cewa a cikin aikin magnetization ko anti-magnetization, yanayin magnetization ba ya canzawa nan da nan zuwa matsayinsa na ƙarshe tare da canjin ƙarfin magnetization, amma yana buƙatar tsari, kuma wannan "sakamakon lokaci" shine dalilin ragowar asarar. Yafi girma a cikin babban mitar 1MHz sama da wasu asarar shakatawa da jujjuyawar maganadisu da sauransu, a cikin canjin wutar lantarki ɗaruruwan KHz na lantarki, adadin asarar saura yayi ƙasa sosai, ana iya yin watsi da shi kusan.

Lokacin zabar ainihin mahimmancin maganadisu mai dacewa, ya kamata a yi la'akari da nau'ikan lanƙwasa daban-daban da halaye na mitar, saboda ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun asarar mitar, juzu'in jikewa da inductance na inductor. Domin a gefe guda halin da ake ciki yana haifar da asarar juriya, yana sa kayan maganadisu suyi zafi, kuma yana haifar da tashin hankali ya karu, a daya bangaren kuma yana rage tasirin maganadisu mai inganci na Magnetic core. Don haka, gwada zaɓar kayan maganadisu tare da babban juriya ko a cikin nau'in tsiri na birgima don rage hasara na yanzu. Sabili da haka, sabon kayan platinum NPH-L ya dace da ƙananan ƙananan ƙarfe foda na ƙananan ƙananan ƙananan mita da na'urori masu ƙarfi.

Asarar ainihin tana faruwa ne ta hanyar canjin yanayin maganadisu a cikin ainihin abu. Asarar da wani abu ke haifarwa shine aikin mitar aiki da jimillar motsi, don haka rage ingantaccen asarar gudanarwa. Asarar ainihin ta samo asali ne ta hanyar hysteresis, eddy current da ragowar asarar ainihin kayan. Don haka, ainihin asarar ita ce jimlar asarar hysteresis, hasara na yanzu da kuma asarar ci gaba. Asarar hysteresis ita ce asarar wutar lantarki da ke haifar da hysteresis, wanda yayi daidai da yankin da ke kewaye da madaukai na hysteresis. Lokacin da filin maganadisu da ke wucewa ta cikin ainihin ya canza, eddy current yana faruwa a cikin ainihin, kuma asarar da eddy current ke haifarwa ana kiransa hasara na yanzu. Ragowar asarar duk hasara ce ban da asarar hysteresis da asarar halin yanzu.
