Kodi inductance mwagwirizana?

Mwagwirizana kupatsidwa ulemu chodabwitsa magwero ndi kuchuluka kwa zipangizo zamagetsi. Nthawi zambiri vuto, pamene munthu mwachindunji takumana ndi mawonetseredwe kwake pa moyo wa tsiku ndi tsiku, koma sakudziwa nkomwe za izo. Tiyeni kukumbukira zakale posachedwapa, kumene waukulu mudziwe kufala kudzera anali analogi chizindikiro. Ndipo tsopano pafupifupi onse zipangizo zamagetsi akhala kunditumiza ku mitundu digito kusinthasintha mawu. chakuti "chithunzi" amadziwika onse. Koma inu ndikudabwa, chimene chimodzimodzi? Ndithudi, nyumba akadali ndi foni basi anatumizanso lamya serviced ndi PBX analogi. Ngati mukuziyenereza amakono "matelefoni mafoni" ndi "oldies", poyerekezera ndi zosemphana mokomera otsiriza. Imvani pa maziko a mayendedwe linasokonekera wailesi kapena ngakhale "zabwino" mawu akadali kulankhulana munthu - izi n'zosadabwitsa. Izi zimachitika chifukwa chingwe telefoni, mawaya ali pafupi wina ndi mnzake, choncho pali kupatsidwa ulemu mwagwirizana mu mizere iwiri. Chitsanzo china ndi anthu kugunda kudina mu okamba TV kapena okamba kompyuta, pamene pali mobilka ndipo ndi kuyitana. Pomaliza, akale IDE-zingwe ndi ochititsa 80 ntchito theka la iwo, pamene winayo 40 Popewa zotsatira umene umabweretsa kupatsidwa ulemu mangawawo. Pali zitsanzo zambiri, zotsatira zonse sizimatanthauza. Nkofunika okha kukumbukira kuti mu nkhani iyi, aliyense "crosstalk" - ichi ndi inductance mangawawo.

Zambiri, mawu akunena za ndondomeko ya zosayembekezereka wa munthu electromotive mphamvu (EMF) mu umodzi wa ochititsa chomwe chili pafupi ndi nthawi imene kusintha zina phindu panopa alipo. Ambiri sangathe anafotokoza ndi kupatsidwa ulemu kulimbikitsana ndi thiransifoma ndi. Mu maonekedwe ake losavuta (a mlandu wapadera), ndi thiransifoma limapangidwa coils awiri chilonda pa yemweyo maginito pachimake. Pamene panopa umayenda mwa waya wa m'modzi wa iwo, pali padziko maginito ilipodi. Choncho anaonekera maginito kamwazi likulowerera chachiwiri koyilo wochititsa kupanga emf m'menemo. Anaonekera kwa panopa anachititsa, zokwanira kutseka anapeza koyilo ndi kupanga unyolo. Ndi kukula mwamphamvu ya kamwazi maginito ndi chinawonjezeka ndi inductance mangawawo. Pofuna kukwaniritsa makhalidwe anakhumba (mwachitsanzo, dzuwa) ntchito njira zosiyanasiyana: kusintha kasinthidwe wa dera maginito; mwapadera imagwiridwa ndi coils kumulowetsa ndi Ave. mwagwirizana inductance chimaonekera ndi variometer a.

bwanji akuwonetseredwa mu zitsanzo yatchulidwa m'nkhani ino? lophweka: pafupifupi milandu (kupatula matelefoni lamya) zili pafupi ochititsa angapo, mmodzi wa wakupambana ndi magetsi. Choncho, pali maginito kupoletsa maginito kamwazi. Otsiriza, ozama ochititsa pafupi induces EMF nawo, komanso unyolo Choncho, malinga ndi lamulo la kupatsidwa ulemu atomu, ndi utuluke panopa. malangizo ake anatsimikiza potsatira ulamuliro wa Lenz.

Mwagwirizana chimagwiritsidwa ntchito zomangamanga ano magetsi. Popeza ena zotsatira zake osafunika anazilemba kumayambiriro kwa nkhani ino, n'zomveka kuti apereke zitsanzo za zothandiza. Mmodzi zipangizo odziwika bwino kwambiri - banja stabilizer mains. Mkati pali thiransifoma (kawirikawiri mtundu toroid) ndi kuchuluka kwa malo, aliyense wa Chofanana mtengo ena voteji. Komanso, ena zipangizo mukhoza kupeza njira chidwi - galvanic kudzipatula. Ndipotu, izi ndi thiransifoma lomwelo (nthawi zina awiri photocoupler), koma osati ntchito yosintha koyefishienti. Chifukwa cha zimenezi, n'zotheka kuchita maginito kamwazi kudzera njira angapo kulankhulana, kupereka mlingo woyenera wa chitetezo magetsi. Yopanga Mwachitsanzo, davit.
