Gano coil

(1) Lokacin zabar da amfani da coil inductance

da farko ya kamata mu yi tunani game da dubawa da aunawa na coil, sannan mu yi la'akari da ingancin coil. Domin gano daidai inductance da ingancin factor Q na inductance coil, ana buƙatar kayan aiki na musamman gabaɗaya, kuma hanyar gwaji ta fi rikitarwa. A cikin aiki mai amfani, wannan nau'in ganowa gabaɗaya ba a aiwatar da shi ba, amma kawai binciken kashewa na coil da hukuncin ƙimar Q. Da farko, ana iya auna juriyar DC na nada ta amfani da fayil ɗin juriya na multimeter, sannan idan aka kwatanta da ainihin ƙimar juriya ta asali ko ƙimar juriya na ƙima. Idan ƙimar juriya da aka auna ta fi ainihin ƙayyadaddun ƙimar juriya ko ƙimar juriya na ƙima, ko da ma'anar ba ta motsa ba (ƙimar juriya tana nufin infinity X), ana iya yanke hukunci cewa nada ya karye. Idan juriyar da aka auna ta yi ƙanƙanta, yana da wuya a kwatanta ko gajeriyar da'ira ce mai tsanani ko gajeriyar da'ira. Lokacin da waɗannan yanayi biyu suka faru, ana iya yanke hukunci cewa nada mara kyau kuma ba za a iya amfani da ita ba. Idan juriyar ganowa ba ta da bambanci da ainihin ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙididdiga ko juriya na ƙididdigewa da ƙima, ana iya yanke hukuncin cewa nada yana da kyau. A wannan yanayin, zamu iya yin hukunci akan ingancin coil, wato, ƙimar Q, bisa ga yanayi masu zuwa. Lokacin da inductance na nada ya kasance iri ɗaya, ƙaramin juriya na DC shine mafi girman ƙimar Q. Mafi girman diamita na waya da aka yi amfani da shi, mafi girman ƙimar Q; Idan an yi amfani da iska mai yawa, yawancin igiyoyin waya, mafi girman ƙimar Q; Ƙananan asarar kayan da aka yi amfani da su a cikin coil bobbin (ko baƙin ƙarfe), haɓaka ƙimar Q. Misali, lokacin da aka yi amfani da takardar siliki ta siliki mai ƙarfi azaman tushen ƙarfe, ƙimarta ta Q ta fi wancan lokacin da aka yi amfani da takardar ƙarfe na silicon na yau da kullun azaman ƙarfe; Karamin ƙarfin da aka rarraba da kuma ɗigon maganadisu na coil, yana haɓaka ƙimar Q. Misali, ƙimar q ɗin murɗar daɗaɗɗen saƙar zuma ta fi ta lallausan iska kuma tana sama da ta bazuwar iska; Lokacin da nada ba shi da garkuwa kuma babu wasu abubuwan ƙarfe a kusa da wurin shigarwa, ƙimar Q ɗin sa ya fi girma, akasin haka, ƙimar Q yana ƙasa. Mafi kusancin garkuwa ko ɓangaren ƙarfe shine ga nada, mafi girman ƙimar Q yana raguwa. Matsayin da ke da mahimmancin maganadisu ya kamata a tsara shi da kyau kuma ya dace; Gilashin eriya da murɗaɗɗen murɗa ya kamata su kasance daidai da juna, wanda ke guje wa tasirin haɗin gwiwar juna.

(2) Za a duba na'urar ta gani kafin shigarwa.

Kafin amfani, duba ko tsarin nada ya tsaya tsayin daka, ko jujjuyawar suna kwance da sako-sako, ko lambobin gubar sako-sako ne, ko Magnetic core yana jujjuyawa, da kuma ko akwai maɓallan zamiya. Waɗannan abubuwan sun cancanci kafin shigarwa.
