Thermosetting yekubatanidza modhi electromagnetic coil SB1034/AB310-B

Main performance indexes ye inductance coil

1.inductive reactance

Hukuru hwekupokana kweiyo inductance coil kuAC ikozvino inonzi inductance XL, ine ohm seyuniti uye ω sechiratidzo. Hukama hwayo ne inductance L uye AC frequency F ndeye XL = 2πfL.

2.quality factor

Hunhu hwemhando Q huwandu hwemuviri hunomiririra kunaka kwecoil, uye Q chiyero cheiyo inductance XL kune yakaenzana kuramba, kureva, Q = XL/R. inductor inoshanda pasi peimwe frequency AC voltage. Iyo yakakwirira iyo Q kukosha kweinductor, iyo idiki kurasikirwa uye yakakwirira kugona. Iyo q kukosha kweiyo coil ine hukama neDC kuramba kwemutyairi, iyo dielectric kurasikirwa kweskeleton, kurasikirwa kunokonzerwa nenhovo kana simbi core, pesvedzero yeakanyanya frequency ganda maitiro uye zvimwe zvinhu. Iko q kukosha kwekoiri inowanzoita makumi kusvika kumazana. Hunhu hwemhando yeinductor hunoenderana neiyo DC kuramba kweiyo coil waya, iyo dielectric kurasikirwa kweiyo coil furemu uye kurasikirwa kunokonzerwa nepakati uye nhoo.

3.distributed capacitance

Chero inductance coil ine imwe capacitance pakati pekuchinja, pakati pezvikamu, pakati pekoiri neinongedzo pasi, pakati pekoiri nemagnetic shield, nezvimwewo. Aya masimba anonzi distributed capacitance ye inductance coil. Kana aya akagovaniswa capacitor akabatanidzwa pamwechete, inova yakaenzana capacitor c yakabatana mukuenderana neiyo inductance coil. Kuvapo kwekugovera capacitance kunoderedza kukosha kweQ kwekoiri uye kunokanganisa kugadzikana kwayo, saka iyo idiki iyo yakagoverwa capacitance yecoil, zviri nani.

4.rated ikozvino

Rated current inoreva kukosha kwezvino iyo inductor haibvumirwi kudarika kana ichishanda zvakanaka. Kana iyo yekushanda ikozvino inodarika yakarongerwa ikozvino, maitiro ekuita einductor achachinja nekuda kwekupisa, uye kunyangwe ichapiswa nekuda kwekupfuura.

5.kusiyana kunobvumirwa

Kutsauka kunobvumidzwa kunoreva kukanganisa kunotenderwa pakati pezita rekuti inductance uye chaiyo inductance yeinductor.

Mainductors anowanzoshandiswa mu oscillation kana kusefa maseketi anoda kurongeka kwepamusoro, uye kutsauka kunobvumidzwa ndeye 0.2 [%] ~ 0.5 [%]; Zvisinei, kururamisa kwemakoiri anoshandiswa pakubatanidza, high-frequency choke nezvimwe zvakadaro haisi yakakwirira; Kutsauka kunobvumirwa ndeye 10 [%] ~ 15 [%].
