Ingancin factor q na inductance coil

1.The factor q shine muhimmin ma'auni don bayyana ingancin coil. Girman Q yana nuna asarar inductance coil. Girman Q, ƙarancin asarar nada. Akasin haka, mafi girman hasara.

2.The ingancin factor Q aka bayyana a matsayin rabo na inductance na coil zuwa DC juriya na coil lokacin da coil aiki a wani mitar AC ƙarfin lantarki. Ana iya bayyana shi ta hanyar dabara kamar haka:

3.Where: W-aiki angular mitar L-coil inductance R-total asarar juriya na nada

4.According to daban-daban lokatai, da bukatun ga ingancin factor Q ma daban-daban. Domin inductance coil a cikin tuning madauki, q darajar ya fi girma, saboda mafi girman darajar q, ƙananan asarar madauki kuma mafi girman ingancin madauki; Don coupling coil, ƙimar q na iya zama ƙasa; Don ƙananan mitoci ko maɗaukakiyar shaƙa, babu buƙatu.

5.A gaskiya ma, haɓaka darajar Q sau da yawa yana iyakance ta wasu dalilai, irin su juriya na DC na mai gudanarwa, asarar dielectric na bobbin, asarar da ke haifar da mahimmanci da garkuwa, da kuma tasirin fata lokacin aiki a. high mita. Saboda haka, ba shi yiwuwa a sanya darajar Q na coil ɗin ya yi girma sosai. Yawanci, ƙimar Q tana da yawa dubun zuwa ɗari, kuma mafi girma shine kawai 500.

6.Lokacin da zaɓin mahimmancin maganadisu, buƙatun mitar aiki da ƙimar Q yakamata a yi la'akari da su. Lokacin da yawan mitar aiki gabaɗaya ya kasance ƙasa da 1Mhz, yakamata a yi amfani da ɗigon maganadisu da aka yi da manganese-zinc ferrite da kyau; Lokacin da mitar aiki ya fi 1 MHz, yakamata a zaɓi ainihin abin maganadisu da aka yi da kayan Ni-Zn-Fe-O. Ƙarƙashin yanayin ƙimar Q mai girma da ƙananan mitar aiki, ya kamata a zaɓi babban girman girman maganadisu.

7.Lokacin da zaɓin mahimmancin maganadisu, buƙatun mitar aiki da ƙimar Q yakamata a yi la'akari da su. Lokacin da yawan mitar aiki gabaɗaya ya kasance ƙasa da 1Mhz, yakamata a yi amfani da ɗigon maganadisu da aka yi da manganese-zinc ferrite da kyau; Lokacin da mitar aiki ya fi 1 MHz, yakamata a zaɓi ainihin abin maganadisu da aka yi da kayan Ni-Zn-Fe-O. Ƙarƙashin yanayin ƙimar Q mai girma da ƙananan mitar aiki, girman girman girman girman ya kamata
