Thermosetting Connection mode electromagnetic koyilo SB1034/AB310-B

Main performance indexes of inductance coil

1.inductive reactance

Kukula kwa kukana kwa koyilo ya inductance ku AC pano kumatchedwa inductance XL, ndi ohm ngati unit ndi ω ngati chizindikiro. Ubale wake ndi inductance L ndi AC pafupipafupi F ndi XL = 2πfL.

2.quality factor

Mtundu wa Q ndi kuchuluka kwa thupi komwe kumayimira mtundu wa koyilo, ndipo Q ndi chiŵerengero cha inductance XL kukana kwake kofanana, ndiye kuti, Q = XL/R. inductor imagwira ntchito pamagetsi ena afupipafupi a AC. Kukwera kwa mtengo wa Q kwa inductor, kumachepetsa kutayika komanso kumapangitsanso magwiridwe antchito. Mtengo wa q wa koyilo umagwirizana ndi kukana kwa DC kwa woyendetsa, kutayika kwa dielectric kwa chigoba, kutayika komwe kumachitika chifukwa cha chishango kapena pachimake chachitsulo, chikoka champhamvu kwambiri pakhungu ndi zinthu zina. Mtengo wa q wa koyilo nthawi zambiri umakhala khumi mpaka mazana. Ubwino wa inductor umagwirizana ndi kukana kwa DC kwa waya wa coil, kutayika kwa dielectric kwa chimango cha koyilo komanso kutayika komwe kumachitika chifukwa cha pachimake ndi chishango.

3.kugawa mphamvu

Koyilo iliyonse ya inductance imakhala ndi mphamvu pakati pa kutembenuka, pakati pa zigawo, pakati pa koyilo ndi malo ofotokozera, pakati pa koyilo ndi chishango cha maginito, ndi zina zotero. Ngati ma capacitor ogawidwawa aphatikizidwa palimodzi, amakhala capacitor wofanana c wolumikizidwa molingana ndi inductance coil. Kukhalapo kwa capacitance yogawidwa kumachepetsa mtengo wa Q wa koyilo ndikuwononga kukhazikika kwake, kotero kucheperako komwe kumagawidwa kwa koyilo kumakhala bwino.

4.voteredwa panopa

Zovoteledwa panopa zimatanthawuza mtengo wamakono umene inductor saloledwa kudutsa pamene ikugwira ntchito bwino. Ngati mphamvu yogwira ntchito ipitilira pakali pano, magawo a magwiridwe antchito a inductor adzasintha chifukwa cha kutentha, ndipo ngakhale adzawotchedwa chifukwa cha kuchuluka.

5.kusiyana kovomerezeka

Kupatuka kovomerezeka kumatanthauza cholakwika chovomerezeka pakati pa inductance mwadzina ndi inductance yeniyeni ya inductance.

Ma inductors omwe amagwiritsidwa ntchito kwambiri pozungulira kapena kusefa amafunikira kulondola kwambiri, ndipo kupatuka kovomerezeka ndi 0.2 [%] ~ 0.5 [%]; Komabe, kulondola kwa ma coil omwe amagwiritsidwa ntchito polumikizana, kutsamwitsa kwafupipafupi ndi zina zotero sizokwera; Kupatuka kovomerezeka ndi 10 [%] ~ 15 [%].
