Thermosetting kev twb kev txuas hom electromagnetic coil SB1034 / AB310-B

Main Performance indexes ntawm inductance kauj

1.inductive reactance

Qhov loj ntawm qhov tsis kam ntawm inductance coil rau AC tam sim no yog hu ua inductance XL, nrog ohm ua chav tsev thiab ω ua lub cim. Nws kev sib raug zoo nrog inductance L thiab AC zaus F yog XL = 2πfL.

2. zoo yam

Qhov zoo tshaj plaws Q yog lub cev muaj nuj nqis sawv cev rau lub kauj zoo, thiab Q yog qhov piv ntawm inductance XL rau nws qhov sib npaug, uas yog, Q = XL / R.. inductor ua haujlwm nyob rau hauv qee zaus AC voltage. Qhov siab dua Q tus nqi ntawm inductor, qhov tsawg dua qhov poob thiab qhov ua tau zoo dua. Q tus nqi ntawm cov kauj yog cuam tshuam nrog DC tsis kam ntawm tus neeg xyuas pib, qhov dielectric poob ntawm lub cev pob txha, qhov poob los ntawm cov ntaub thaiv npog lossis cov tub ntxhais hlau, kev cuam tshuam ntawm cov tawv nqaij ntau zaus thiab lwm yam. Q tus nqi ntawm lub kauj yog feem ntau kaum mus rau pua pua. Qhov zoo tshaj plaws ntawm cov inductor muaj feem xyuam rau DC tsis kam ntawm cov coil hlau, qhov dielectric poob ntawm lub kauj ncej thiab qhov poob los ntawm cov tub ntxhais thiab cov ntaub thaiv npog.

3.distributed capacitance

Txhua qhov inductance coil muaj qee qhov kev hloov pauv, nruab nrab ntawm cov txheej, nruab nrab ntawm lub kauj thiab hauv av, nruab nrab ntawm lub kauj thiab cov hlau nplaum, thiab lwm yam. Yog tias cov capacitors faib ua ke ua ke, nws dhau los ua qhov sib npaug ntawm cov capacitor c txuas nrog rau qhov sib npaug nrog lub inductance coil. Lub hav zoov ntawm kev faib capacitance txo qis Q tus nqi ntawm lub kauj thiab ua rau nws ruaj khov, yog li qhov me me ntawm cov khoom faib tawm ntawm lub kauj, qhov zoo dua.

4.rated tam sim no

Rated tam sim no hais txog tus nqi tam sim no uas tus inductor tsis pub dhau thaum nws ua haujlwm ib txwm. Yog tias qhov ua haujlwm tam sim no tshaj qhov ntsuas tam sim no, qhov kev ua haujlwm tsis zoo ntawm cov inductor yuav hloov pauv vim cua sov, thiab txawm tias nws yuav raug hlawv vim overcurrent.

5. tso cai variation

Tso cai sib txawv yog hais txog qhov ua yuam kev ntawm qhov nominal inductance thiab qhov tseeb inductance ntawm inductor.

Inductors feem ntau siv hauv oscillation lossis filtering circuits xav tau qhov tseeb siab, thiab qhov tso cai sib txawv yog 0.2 [%] ~ 0.5 [%]; Txawm li cas los xij, qhov tseeb ntawm cov coils siv rau kev sib txuas, lub tshuab choke siab thiab lwm yam tsis siab; Qhov tso cai sib txawv yog 10 [%] ~ 15 [%].
