ʻO ke ʻano hoʻohui thermosetting electromagnetic coil SB1034/AB310-B

Nā papa kuhikuhi hana nui o ka coil inductance

1.inductive reactance

ʻO ka nui o ke kūpaʻa o ka inductance coil i ka AC i kēia manawa ua kapa ʻia ʻo inductance XL, me ka ohm ka ʻāpana a me ka ω ka hōʻailona.ʻO kona pilina me ka inductance L a me ka pinepine AC F he XL=2πfL.

2.quality kumu

ʻO ke kumu maikaʻi Q ka nui kino e hōʻike ana i ka maikaʻi o ka coil, a ʻo Q ka ratio o ka inductance XL i kona kūpaʻa like, ʻo ia hoʻi, Q = XL/R. Ke hana nei ka inductor ma lalo o kekahi alapine AC.ʻO ke kiʻekiʻe o ka waiwai Q o ka inductor, ʻoi aku ka liʻiliʻi o ka nalowale a ʻoi aku ka kiʻekiʻe o ka pono.ʻO ka waiwai q o ka coil e pili ana i ke kū'ē DC o ka conductor, ka poho dielectric o ka iwi iwi, ka poho i hanaʻia e ka pale a iʻole ka hao hao, ka hopena o ka hopena o kaʻili kiʻekiʻe a me nā mea'ē aʻe.ʻO ka waiwai q o ka pōʻai he ʻumi a hiki i nā haneli.ʻO ke kumu maikaʻi o ka inductor e pili ana i ke kūpaʻa DC o ka uea coil, ka nalowale o ka dielectric o ka pahu coil a me ka nalowale i kumu a me ka pale.

3.distributed capacitance

Kekahi inductance coil i kekahi capacitance ma waena o huli, ma waena o nā papa, ma waena o ka wili a me ka kuhikuhi kahua, ma waena o ka wili a me ka magnetic pale, etc. Ua kapaia keia mau capacitances ka puana puana o ka inductance coil.Inā hoʻohui pū ʻia kēia mau capacitors i puʻunaue ʻia, e lilo ia i capacitor c like i hoʻohui ʻia me ka coil inductance.ʻO ka loaʻa ʻana o ka capacitance puʻupuʻu e hōʻemi i ka waiwai Q o ka coil a hoʻohaʻahaʻa i kona kūpaʻa, no laila ʻoi aku ka liʻiliʻi o ka capacitance puʻupuʻu o ka coil, ʻoi aku ka maikaʻi.

4.heluhelu i kēia manawa

ʻO ka helu i kēia manawa e pili ana i ka waiwai o kēia manawa ʻaʻole ʻae ʻia ka inductor e hala ke hana maʻamau.Inā ʻoi aku ka hana o kēia manawa ma mua o ka manawa i helu ʻia, e loli nā ʻāpana hana o ka inductor ma muli o ka hoʻomehana ʻana, a e puhi ʻia nō hoʻi ma muli o ka overcurrent.

5.allowable hoʻololi

ʻO ka ʻae ʻia ʻana e pili ana i ka hewa i ʻae ʻia ma waena o ka inductance nominal a me ka inductance maoli o ka inductor.

Pono nā inductors maʻamau i ka oscillation a i ʻole kānana kaapuni i ka pololei kiʻekiʻe, a ʻo ka ʻae ʻia ʻana he 0.2 [%] ~ 0.5 [%];Eia naʻe, ʻaʻole kiʻekiʻe ka pololei o nā coils i hoʻohana ʻia no ka hoʻopili ʻana, kiʻekiʻe-frequency choke a pēlā aku;ʻO ka haʻalele ʻae ʻia ʻo 10 [%] ~ 15 [%].
