Yuav ua li cas yog alternating tam sim no?

Hais txog ntawm ntau yam hluav taws xob tam sim no tag nrho cov tham txawm nyob rau hauv physics qhia hauv tsev kawm ntawv. Rau ib co, cov no yog cov tsuas theoretical paub, los txhawb kev nkag siab ntawm lub ntiaj teb no kev txiav txim, thaum lwm tus yuav xaiv ib tug tshwj xeeb, ncaj qha mus txog rau lub zog. Txawm li cas los ntawm qhov no, txhua leej txhua tus paub hais tias muaj yog ib tug ncaj thiab alternating tam sim no. Qhov thib ob lug siv hluav taws xob nws variant tau yooj yim mus transformation thiab motors rau nws cov hauv paus yog ntau yooj yim thiab txhim khu kev qha.

Alternating tam sim no - ib tug muaj zog ntawm them hais los ntawm tus neeg xyuas pib, uas nyob rau tej lub sij hawm Team sib (sij hawm) yuav hloov nyob rau hauv cov kev taw qhia thiab qhov ntau. Lub npe nrov sine yoj cia li qhia tau hais tias nws tus cwj pwm. Yuav kom nkag siab txog cov keeb kwm ntawm lub alternating tam sim no, xav txog lub hauv paus ntsiab lus ntawm qhov nyuaj generating ntaus ntawv. Nws yog raws li nyob rau tshwm sim ntawm electromagnetic induction, uas muaj nyob rau hauv cov tsos ntawm tam sim no nyob rau hauv lub kaw conductive voj uas tshuam kab ntawm magnetic quab yuam.

Nyob rau axis, nruab nrab ntawm ob magnet ncej (sab qaum teb thiab sab qab teb) yog muab tso rau ncej ntawm conductive khoom (tooj liab hlau). Nws xaus los ntawm txoj kev zawv zawg cov neeg uas tus txhuam mechanism yog kev cob cog rua rau lub load Circuit Court los yog voltage measuring dais. Lub thav duab yuav tig ib ncig ntawm ib tug axis, uas yog muaj nyob rau. Nruab nrab ntawm lub magnet tug muaj yog invisible magnetic teb kab. Thaum tus ncej yog rotated, nws ob sab hla txoj kab, uas ua rau ib tug alternating tam sim no. Yog vim li cas rau nws tshwm sim yog tshwm sim los ntawm "knocking tawm" cov magnetic teb ntawm lub electron orbits nyob deb ntawm lub nucleus. Txawm tias cov kev taw qhia ntawm cov EMF (electromotive quab yuam) nyob rau hauv ob tus ntoo khaub lig seem ntawm tus ncej yeej ib txwm rov qab, yog tias koj saib nyob rau ntawm qhov saw raws li ib tug tag nrho, nws yuav tseeb hais tias lawv yog unidirectional. EMF nce mus txog ib tug tshaj plaws thaum lub caij ntawm kev tshuam ntawm txoj kab ntawm kev quab yuam thiab kis tau los ntawm xoom ntawm ib tug kab rov tav qhov chaw qhov chaw ntas (txheejtxheem sinusoid, nws yog tseem tsis tseg crosses pes tsawg tus nqi). Qhov ntawd yog li ntawd, tej yam yooj yim.

Ntawm cov hoob kawm, tus tiag tiag generators, generating ib tug alternating tam sim no, yog xav paub ntau tham tshaj lub thav duab ntawm cov hlau, tab sis lub hauv paus ntsiab lus ntawm lawv lub lag luam yog tib yam. Thauj tog rau nkoj nrog windings (ua tau - ib tug plurality ntawm ntas ntawm reference) rotates nyob rau hauv lub magnetic teb ntawm lub stator lwm quab yuam: qhov no tej zaum yuav lub zog ntawm kev ntog dej; zog chav generated thaum tshav kub kub ntawm lub nuclear reactor; cua siab, thiab li ntawd. Cov uas ua voltage zoo nkaus li nyob rau winding terminals. Nws tseem mus cuag cov load thiab cov AC tsis ntev ntev. Feem ntau generated tsis tau ib tug, tab sis peb theem.

Raws li twb tau hais, nyob rau hauv tas li ntawd mus nce mus nce los, thiab muaj ib tug tsis tu ncua tam sim no. Nws lub npe hais lus rau nws tus kheej: tsis muaj kev hloov nyob rau hauv cov kev taw qhia ntawm lub zog tsis tshwm sim. Qhov no tam sim no yog ib txwm qhia los ntawm ntxiv mus rho tawm. Cov theem nrab zog qhov chaw, xws li cov roj teeb, los ntawm txoj kev tshuaj tshua noog nyob rau hauv nws tus kheej yog xws li ib tug tam sim no, li no cov cim "+" thiab "-". Raws li tus piv nrog ib tug kuj tsis paub meej, nws muaj ib tug xov tooj ntawm cov nta. Kuv xav hais tias "kev txawj thiab weaknesses", tab sis nws tsis yog - nws yog tus "peculiarities". Piv txwv li, lub DC tsav ua rau nws ua tau rau ntseeg nkaws kho cov kev ceev ntawm kev sib hloov ntawm lub armature, thiab tsis stepwise, tshwj xeeb tshaj yog zaus converters ntiav complex tsis tas. Ntxiv mus, yuav luag tag nrho cov hluav taws xob circuits no yog tsim los ua hauj lwm nrog no zoo ntawm lub hwj chim, raws li lawv yog yooj yim rau kev tswj. Tau ib tug ncaj qha tam sim no los ntawm lub AC yog heev yooj yim - nws yog tsim nyog los "ncaj" tshwj xeeb semiconductor Cheebtsam (diodes thiab diode choj). Nws tshwm sim hlais sinusoid peaks nyob rau hauv ob ib nrab sij hawm. Qhov seem pulsating xwm ntawm lub resulting tam sim no muaj peev xwm kuj yuav tus.
