Fais fab Transformers: Lub Quiet Heroes khaws koj lub teeb rau
Tej zaum koj tau taug kev los ntawm cov thawv hlau ntsuab loj hauv ib tus neeg lub vaj ib puas zaug thiab tsis tshua pom lawv. Lawv tsuas zaum nyob ntawd, tej zaum muab lub suab qis tam sim no thiab tom qab ntawd, saib zoo li ib feem ntawm qhov chaw. Tab sis ua ncaj ncees, tsis muaj cov khoom tsis txaus ntseeg, hluav taws xob los ntawm lub zog cog mais (lossis ntau pua mais) deb yuav tuaj txog tsis muaj zog lossis muaj kev phom sij heev rau ntsaws txhua yam rau hauv.
Xav txog seb hluav taws xob tau txais mus rau koj lub tsev li cas. Cov chaw tsim hluav taws xob feem ntau tsis muaj nyob ze cov nroog -xav tias tej thaj chaw deb nrog hydro dams, cua ua liaj ua teb, thee, gas, txawm li cas los xij. Kev xa hluav taws xob nyob deb yog qhov nyuaj vim tias hluav taws xob poob lub zog dhau mus ntev, zoo li dej siab poob rau hauv lub hose ntev heev.
Voltage yog lub hauv paus "siab" uas thawb hluav taws xob nrog. Txhawm rau kom nws mus txog ntau pua mais yam tsis tau ploj mus yuav luag tsis muaj dab tsi, cov khoom siv hluav taws xob crank nws txoj kev nce -feem ntau mus txog ntau pua txhiab volts. High voltage=tsawg poob, yooj yim li ntawd.
Tab sis tom qab ntawd nws tshwm sim nyob ze koj lub zej zog ... thiab tam sim ntawd qhov kev npau taws siab yog qhov kawg uas koj xav ntaus koj cov chav ua noj. Koj lub khob cij, lub xov tooj charger, tub yees -lawv yuav tau kib tam sim ntawd, lossis phem dua.
Qhov ntawd yog qhov chaw transformer tuaj thiab txuag lub hnub. Nws nce qib voltage mus rau tej yam muaj kev nyab xeeb thiab siv tau -zoo li 120V lossis 240V nyob ntawm seb koj nyob qhov twg. Nws yog daim phiaj tswj lub siab, ua kom lub zog muaj zog txaus los khiav koj lub tshuab ziab khaub ncaws tab sis tame txaus kom tsis txhob tshuab koj lub laptop.
Vim li cas peb tsis tuaj yeem xa cov hluav taws xob hauv tsev ib txwm muaj thoob plaws lub tebchaws
Yog tias cov khoom siv hluav taws xob sim thawb 120 volts los ntawm qhov chaw fais fab nyob deb mus rau hauv koj lub nroog, feem ntau nws yuav tau noj nyob rau hauv txoj kev. Cov xov hlau lawv tus kheej tsim kev tiv thaiv (xav kev sib txhuam hauv cov yeeb nkab), tig lub zog mus rau qhov tsis muaj cua sov. Ntxiv rau qhov voltage yuav poob ntau heev tom qab tsuas yog ob peb mais uas koj nyuam qhuav tau txais lub flicker thaum kawg.
Yog li txoj cai ntawm lub tshuab hluav taws xob lawv siv "step- nce" transformers los txhawb lub zog hluav taws xob saum ntuj - siab- qee zaum 300 kV, 500 kV lossis ntau dua. Nws zoo li muab lub zog tso rau hauv overdrive yog li nws tuaj yeem caij nkoj mus ntev nrog kev poob qis. Engineers hu qhov ntev -haul ib feem " kis tau tus mob." Cov hlau loj loj no hla lub teb chaws? Qhov ntawd yog txoj kev loj hauv xeev hluav taws xob.
Los ze rau tsev nws yog ib zaj dab neeg sib txawv- uas yog theem "kev faib tawm". Lub hwj chim yuav tsum tau tamed dua ua ntej nws mus txog koj txoj kev.
Lub Invisible Khawv koob: Yuav ua li cas hloov pauv ua haujlwm tiag tiag (tsis muaj qhov txav!)
Muab koj lub pob ntseg mus rau lub tshuab hloov pauv thiab koj yuav hnov cov suab nrov tsis tu ncua, tab sis tsis muaj dab tsi tig los yog tso rau hauv. Tsis muaj zog, tsis muaj pistons. Txawm li cas los xij nws txav ntau lub zog hla qhov sib txawv me me uas siv ... qhov tseem ceeb ntawm cov hlau nplaum.
Nws yog tib lub tswv yim tom qab wireless xov tooj chargers. Sab hauv muaj ib lub kauj tseem ceeb uas tau txais cov khoom siv hluav taws xob siab -voltage. Qhov tam sim no tsim ib qho chaw sib nqus hloov pauv - nthuav dav thiab sib tsoo 60 zaug ib pliag (lossis 50, nyob ntawm koj lub tebchaws). Qhov chaw pulsing hla mus rau lub kauj thib ob nyob ze (lawv yeej tsis kov), thiab boom- cov electrons nyob rau hauv lub kauj thib ob pib txav ib yam nkaus. Hluav taws xob dhia qhov sib txawv yam tsis muaj cov xov hlau txuas rau lawv.
Qhov kev dag no yog ua tsaug rau Faraday txoj cai ntawm electromagnetic induction, pom rov qab rau xyoo 1830. Ib coil "hais lus" rau lwm tus los ntawm kev sib nqus. Zoo nkauj heev thaum koj xav txog nws.
Tau kawg nws tsis yog 100% zoo tag nrho -qee qhov chaw sib nqus nqus tawm, tig mus rau hauv qhov hluav taws kub khib nyiab. Tias yog vim li cas engineers obsess txog kev txo qis "flux to."
Dab tsi hauv lub thawv: Hlau, tooj liab (lossis Aluminium), thiab Kev Tsim Kho Ntse
Txhawm rau ua kom qhov chaw sib nqus tsom thiab ua haujlwm tau zoo, cov tub ntxhais tsis yog cov khoom siv hlau. Nws yog ua los ntawm ntau txhiab tus super-cov ntawv nyias nyias ua ke ua ke-zoo li nplooj ntawv hauv phau ntawv. Vim li cas? Ib qho khoom tseem ceeb yuav tsim cov eddy tam sim no uas nkim lub zog raws li cua sov. Cov laminations tawg cov loops, yog li cov hlau nplaum mus qhov twg nws yuav tsum tsis txhob ua noj lub transformer.
Qhwv ib ncig ntawm cov tub ntxhais yog cov windings -coils ntawm hlau. Feem ntau tooj liab vim tias nws yog tus neeg xyuas pib zoo tshaj plaws, khaws cov khoom sib txuas, thiab ua haujlwm txias dua ... tab sis nws kim thiab hnyav. Rau qhov loj dua, hauv av-mounted units, aluminium yog ntau- pheej yig dua, sib dua, txawm tias koj xav tau ntau dua los ua tib yam tam sim no.
Qhov kev hloov voltage yog tag nrho hais txog tus naj npawb ntawm cov lem hauv txhua lub kauj. Ntau dua nyob rau sab siab-voltage, tsawg dua ntawm qhov qis-voltage sab=kauj ruam- nqis. Nws yog qhov yooj yim lej: hloov piv=voltage piv.
Khaws Cia Cia: Roj vs. Cua
Txhua qhov kev hloov hluav taws xob no ua rau muaj cua sov loj. Cov transformers loj feem ntau zaum hauv lub tank ntawm cov roj ntxhia tshwj xeeb uas nqus cov cua sov los ntawm cov coils thiab cov tub ntxhais, tom qab ntawd dhau mus rau qhov txias fins sab nraud. Cov roj tsis yog tsuas yog ua kom txias xwb- nws kuj yog ib qho hluav taws xob zoo insulator, tiv thaiv sparks thiab arcs sab hauv.
Qee qhov chaw tsis tuaj yeem muaj cov roj tank loj (xav tias qhov chaw sab hauv tsev, siab -nce, tsev kawm ntawv, khw, lossis thaj chaw muaj kev cuam tshuam ib puag ncig). Cov no siv qhuav-hom transformers- huab cua-cooled nrog tshwj xeeb resins thiab vents. Lawv feem ntau loj dua, kub dua, tab sis txoj kev nyab xeeb dua thaum hluav taws kub los yog xau yog qhov kev txhawj xeeb tiag tiag.
Ntawd Classic Hum - Nws tsis yog qhov teeb meem (feem ntau)
Lub suab nrov qis uas koj hnov yog magnetostriction- cov tub ntxhais hlau tau nthuav dav thiab sib cog lus me me raws li cov hlau nplaum sib nqus tig rov qab. Nws vibrates tag nrho lub tank zoo li lub khob loj loj hais lus. Ib txwm, khov kho hum=noj qab nyob zoo. Sudden nrov rattling, clanking, los yog irregular buzzing? Qhov ntawd tuaj yeem txhais tau tias muaj qhov xoob xoob, teeb meem rwb thaiv tsev, lossis dhau sijhawm - lub sijhawm rau cov neeg siv hluav taws xob los xyuas nws.
Kais Changers: Ua kom koj qhov hluav taws xob ruaj khov
Lub zog xav tau hloov txhua hnub- thaum sawv ntxov kas fes maj, yav tsaus ntuj AC moj tej tawg, lub Hoobkas pib. Voltage sags lossis spikes tuaj yeem rhuav tshem cov khoom siv. Yog li ntau lub tshuab hloov pauv muaj cov kais hloov pauv uas tau txais (lossis qee zaum manually) kho tus lej hloov pauv hauv lub kauj kom tso zis voltage pob zeb- khov kho.
Thaum Tej Yam Tsis Zoo: Bushings thiab Kev Nyab Xeeb
Cov ribbed grey insulators lo tawm sab saum toj? Bushings. Lawv yog qhov siab -voltage nkag / tawm cov ntsiab lus thiab hmoov tsis zoo yog ib qho ntawm feem ntau tsis ua hauj lwm tej qhov chaw - tawg los ntawm hnub nyoog, xob laim, muaj kuab paug buildup, thiab lwm yam. Thaum lawv ua tsis tau tejyam, koj muaj peev xwm tau txais arcing, roj leaks, los yog txawm ib tug blown transformer.
Yog tias koj puas tau pom cov roj ntws mus rau sab, haus luam yeeb, qhib qhov rooj, lossis suab nrov txawv, nyob hauv txoj kev rov qab -tsawg kawg 30–40 ko taw-thiab hu rau lub chaw siv hluav taws xob lossis kev pabcuam xwm txheej ceev tam sim ntawd.
Kab hauv qab
Lwm zaus koj hla ib qho ntawm cov thawv ntsuab los yog hnov cov suab nrov ntawm tus ncej-mounted unit, koj yuav paub tias muaj dab tsi tshwm sim hauv: ob lub coils ntsiag to ua lag luam lub zog los ntawm tus choj hlau nplaum tsis pom, taming qus siab - lub zog hluav taws xob kom koj lub xov tooj them, koj lub tub yees khiav, thiab koj lub teeb nyob twj ywm.
Lawv yog cov tawv, txhim khu kev qha cov khoom siv ... tab sis lawv tuav lub zog txaus ntshai heev. Ua tib zoo saib xyuas lawv-tsis txhob nce toj, tsis txhob khawb ze, khaws cov nroj tsuag kom nkag tau yooj yim-thiab yog tias muaj qee yam tsis zoo, cia cov neeg ua haujlwm tau zoo.
Qhov ntawd yog zaj dab neeg transformer nyob rau hauv ib tug nutshell. Zoo nkauj npaum li cas ib yam dab tsi zoo tib yam ua rau lub neej niaj hnub ua haujlwm zoo, txoj cai?
