Hluav taws xob rau lub "dummies". Tsev kawm ntawv rau lub electrician

Peb muaj me ntsis khoom nyob rau hauv lub ntsiab lus: "Hluav taws xob rau Beginners." Nws yuav muab ib tug thawj zaug kev nkag siab ntawm cov lus thiab phenomena txog rau lub zog ntawm electrons nyob rau hauv cov hlau.

Nta ntawm lub sij hawm

Hluav taws xob yog lub zog ntawm me me them hais tsiv nyob rau hauv conductors nyob rau hauv ib tug tej yam kev taw qhia.

Yog hais tias DC yog tsis cai hloov nyob rau hauv nws cov magnitude thiab kev coj ntawm lub zog rau ib tug tej lub sij hawm ntawm lub sij hawm. Yog hais tias lub tam sim no qhov chaw electrochemical cell (roj teeb) yog xaiv, nyob rau hauv uas cov ntaub ntawv tus nqi tsiv orderly los ntawm qhov tsis zoo ncej mus rau lub zoo kawg. Tus txheej txheem ntxiv raws li ntev raws li nws tsis tau kiag li ploj.

Alternating tam sim no tseg hloov qhov ntau thiab cov kev taw qhia ntawm lub zog.

Scheme AC kis tau tus mob

Wb sim kom to taub dab tsi theem hluav taws xob. Lo lus no yog hnov los ntawm tag nrho cov, tab sis tsis yog txhua tus to taub nws cov ntsiab lus tseeb. Peb yuav tsis delve rau hauv cov lus thiab lub ntsiab lus, tsuas xaiv cov ntaub ntawv uas yuav tsum tau handyman. Ib tug peb-theem network yog ib txoj kev ntawm kis hluav taws xob tam sim no, nyob rau lub peb sib txawv nyob ntawm tej, tam sim no tsev, thiab ib tug yog nws rov qab. Piv txwv li, muaj ob nyob ntawm tej nyob rau hauv ib tug hluav taws xob Circuit Court.

Nyob rau hauv thawj hlau rau tus neeg, xws li lub hwj kais, yog tam sim no. Qhov thib ob hlau yog siv rau cov rov qab. Thaum qhib, xws li ib tug Circuit Court, lub khiav ntawm hluav taws xob xwb nyob rau hauv lub neeg xyuas pib yuav tsis tau. Qhov no daim ntawv qhia txog ib tug ib leeg-theem Circuit Court. Yuav ua li cas yog lub sij hawm ntawm hluav taws xob? Theem hlau ntseeg hais tias, los ntawm cov uas ib tug hluav taws xob tam sim no ntws. Hu ua pes tsawg hlau, los ntawm cov uas rov qab los. Nyob rau hauv lub peb-theem Circuit Court yog tam sim no ib zaug peb theem nyob ntawm tej.

Hluav taws xob cov ntaub thaiv npog nyob rau hauv lub tiaj yog yuav tsum tau rau cov ceevxwm uas hluav taws xob tam sim no nyob rau hauv tag nrho cov chav. Lub peb-theem network yog suav tias yog nqi-zoo, vim hais tias nws tsis yuav tsum tau ob nyob ntawm tej xoom rau lawv. Thaum nce cov neeg tam sim no yog phua rau hauv peb theem, thiab nyob rau hauv txhua muaj yog pes tsawg. Earthing, uas yog siv nyob rau hauv ib-theem network, tsis dais lub workload. Nws yog ib tug fuse.

Piv txwv li, yog cov kev hem thawj strike poob siab, hluav taws kub, thaum ib tug luv luv Circuit Court tshwm sim. Yuav kom tiv thaiv xws li ib tug teeb meem no, tam sim no tus nqi yuav tsum tsis txhob ntau tshaj ib tug muaj kev ruaj ntseg theem, qhov tshaj tawm rau hauv av.

Cov phau ntawv "Lub tsev kawm ntawv rau lub electrician," yuav pab tau beginners rau masters rau nrog ib co breakdowns ntawm cov khoom siv. Piv txwv li, yog hais tias muaj teeb meem nyob rau hauv lub lag luam los ntawm cov hluav taws xob lub cev muaj zog ntawm lub tshuab ntxhua khaub ncaws, qhov tam sim no yuav poob rau hauv txheej hlau casing.

Nyob rau hauv lub qhaj ntawv ntawm grounding tus nqi yuav muab faib mus rau lub tshuab. Thaum koj kov nws ob txhais tes, raws li earthing ua neeg uas tau txais ib tug hluav taws xob poob siab. Nyob rau hauv lub xub ntiag ntawm lub hauv av nyob ntawm tej xws li ib tug teeb meem no yuav tsis tshwm sim.

hluav taws xob nta

Phau ntawv "Hluav taws xob rau Dummies" yog nrov nrog cov neeg uas nyob deb ntawm physics, tab sis npaj rau kev mus siv txoj kev paub no rau tswv yim lub hom phiaj.

Lub hnub ntawm cov tsos ntawm cov hluav taws xob engineering yog suav hais tias yog thaum pib ntawm lub puas tawm xyoo dhau. Nws yog nyob rau ntawm lub sij hawm no, tus thawj tam sim no qhov chaw tau raug tsim. Lub discoveries ua nyob rau hauv lub teb ntawm magnetism thiab hluav taws xob, muaj kev tswj los qhia txhawb kev kawm nrog lub ntsiab tshiab thiab tseeb, muaj ib qho tseem ceeb cov tswv yim tseem ceeb.

Phau ntawv "Lub tsev kawm ntawv rau lub electrician" assumes paub nrog yooj yim cov ntsiab lus uas muaj feem xyuam rau hluav taws xob.

Lub tswv yim rau beginners

Nyob rau hauv muaj ntau yam collections nyob rau hauv physics muaj complex hluav taws xob Circuit Court, raws li zoo raws li ib tug ntau yam ntawm coj txawv txawv cov ntsiab lus uas. Yuav kom beginners yuav to taub tag nrho cov intricacies ntawm no ceg ntawm physics, tshwj xeeb nyiaj "Hluav taws xob rau Dummies" yog tsim. A ncig ntawm lub ntiaj teb no ntawm lub electron yuav tsum pib nrog ib tug saib xyuas ntawm lub theoretical tswv yim thiab tej kev cai. Piv txwv piv txwv ntawm cov keeb kwm tseeb siv nyob rau hauv phau ntawv "Hluav taws xob rau Dummies" los pab novice electrician tau paub. Mus xyuas kev kawm, koj yuav tau siv ntawv, kev xeem, ce muaj feem xyuam rau hluav taws xob.

Yog hais tias koj twb paub lawm hais tias koj muaj txaus theoretical paub nyob rau hauv thiaj li yuav tiv nrog txuas hluav taws xob thaiv, xa mus rau phau ntawv no rau lub "Dummies".

Kev nyab xeeb thiab kev xyaum

Ua ntej koj yuav tau ua tib zoo saib xyuas tus seem kev soj ntsuam txog nrog kev ruaj ntseg. Nyob rau hauv cov ntaub ntawv no, thaum lub sij hawm ua hauj lwm muaj feem xyuam rau hluav taws xob, yuav tsis tshwm sim muaj xwm txheej ceev, tej rau kev kho mob.

Nyob rau hauv thiaj li yuav paub nyob rau hauv kev xyaum lub theoretical paub mas yuav kis tau tom qab nws tus kheej-kev kawm cov kev qhia tswj ntawm hluav taws xob engineering, koj yuav pib nrog lub cuab yeej siv qub. Ua ntej yuav pib kho nco ntsoov nyeem cov lus qhia uas tuaj nrog cov ntaus ntawv. Tsis txhob hnov qab los dag hais tias cov hluav taws xob tsis yog yuav tsum tau.

Electric tam sim no yog txuam nrog lub zog ntawm electrons nyob rau hauv conductors. Yog hais tias lub yam khoom uas yog tsis muaj cai tam sim no, nws yog hu ua ib tug dielectric (insulator).

Rau kev tshem ntawm free electrons los ntawm ib tug ncej mus rau lwm therebetween yuav tsum muaj ib tug tej yam tej zaum txawv.

Cov kev siv ntawm lub tam sim no ntws los ntawm tus neeg xyuas pib nrog cov xov tooj ntawm electrons dua los ntawm tus ntoo khaub lig seem ntawm tus neeg xyuas pib.

Tus nqi ntawm tso cai ntawm lub tam sim no muaj feem xyuam rau cov khoom, ntev, tus ntoo khaub lig seem cheeb tsam ntawm tus neeg xyuas pib. Los ua qhov ntev ntawm lub hlau, cov kuj tsub kom.

xaus

Hluav taws xob yog ib qho tseem ceeb thiab complex ib feem ntawm physics. Phau ntawv "Hluav taws xob rau dummies" tham txog qhov siv ntau characterizing lub efficiency ntawm electric motors. Voltage ntsuas units yog volts, tam sim no yog muab nyob rau hauv amperes.

Tej qhov chaw ntawm hluav taws xob lub zog muaj ib tug tej yam hwj huam. Nws txhais tau tias tus nqi ntawm cov hluav taws xob generated los ntawm cov ntaus ntawv rau ib tug tej lub sij hawm ntawm lub sij hawm. zog tau txais kev pab (tub yees, ntxuav machines, kettles, irons) yog tseem hwj chim siv hluav taws xob thaum lub sij hawm lub lag luam. Yog hais tias qhov kev kawm, muaj peev xwm yuav nqa tawm zauv, txiav txim approximate nqi them rau ib lub tshuab.
