Dab tsi yog qhov txawv ntawm kaw thiab qhib chains?

Hluav taws xob ntws los ntawm ib lub voj voog thiab lub voj voog tuaj yeem tswj tau qhib thiab kaw raws li xav tau.

Tab sis qee zaum qhov tam sim no tuaj yeem cuam tshuam lossis luv luv tuaj yeem tshwm sim. Tsis tas li ntawd, muaj txoj hauv kev uas peb tuaj yeem txhob txwm tshaj tawm cov saw hlau kom qhib lossis kaw. Yuav kom nkag siab tag nrho cov no, peb yuav tsum paub qhov txawv ntawm qhov qhib thiab kaw lub voj.

Qhov txawv ntawmn qhib thiab kaw ib lub voj voog yog tias lub voj voog qhib thaum muaj qhov tawg ntawm qhov chaw ntawm nws txoj kev uas tiv thaiv kev ntws ntawm hluav taws xob. Nws ntws tsuas yog thaum tsis muaj qhov tawg, piv txwv li thaum lub voj voog kaw tag. Peb tuaj yeem qhib lossis kaw ib lub voj voog nrog lub qhov hloov lossis cov cuab yeej tiv thaiv xws li fuse lossis Circuit Court breaker.

Kuv yuav piav qhia qhov sib txawv no kom ntxaws nrog cov piv txwv thiab cov duab kos, thiab tom qab ntawd taw qhia lwm qhov sib txawv kom nkag siab zoo dua.

Lub voj voog qhib thiab kaw yog dab tsi?

qhib lub voj voog

Hauv ib lub voj voog qhib, tsis muaj hluav taws xob tuaj yeem ntws los ntawm nws.

Tsis zoo li lub voj voog kaw, hom Circuit Court no muaj txoj hauv kev tsis tiav uas cuam tshuam lossis tawg. Discontinuity ua rau cov tam sim no ntws tsis tau.

kaw Circuit Court

Nyob rau hauv ib lub voj voog kaw, hluav taws xob tam sim no tuaj yeem ntws los ntawm nws.

Tsis zoo li qhov qhib Circuit Court, hom Circuit Court no muaj tag nrho txoj hauv kev tsis muaj kev cuam tshuam lossis tawg. Kev txuas ntxiv tso cai rau tam sim no ntws.

Piv txwv

Hauv daim duab hluav taws xob hluav taws xob, peb feem ntau qhia txog qhov qhib thiab kaw ntawm lub voj voog nrog cov nkhaus nkhaus thiab ib qho tuab, raws li pom hauv daim duab hauv qab no.

Yuav ua li cas qhib lub kaw Circuit Court thiab vice versa

Lub kaw lus kaw tuaj yeem qhib, lossis rov ua dua, qhov qhib Circuit Court tuaj yeem raug kaw.

Yuav ua li cas qhib lub voj kaw?

Yog tias qhov tam sim no ntws los ntawm lub kaw lus kaw raug cuam tshuam, nws qhib.

Ib lub voj voog kaw tuaj yeem qhib tau yog tias, piv txwv li, qhov qhib tau tshwm sim nyob rau hauv ib qho chaw hauv Circuit Court vim yog cov hlau tawg. Tab sis qhov qhib ntawm lub kaw lus kaw kuj tuaj yeem tswj tau txhob txwm los yog lub hom phiaj los ntawm cov keyboards, fuses, thiab Circuit Court breakers.

Yog li, qhov pib kaw Circuit Court tuaj yeem qhib tau los ntawm cov xaim tawg los ntawm kev kaw lub Circuit Court breaker yog tias lub fuse raug tshuab lossis lub Circuit Court breaker tripped.

Yuav ua li cas qhib Circuit Court dhau los ua lub kaw lus kaw?

Yog tias tam sim no pib ntws los ntawm qhov qhib Circuit Court, nws yuav tsum raug kaw.

Ib qho kev qhib Circuit Court tuaj yeem raug kaw yog tias, piv txwv li, kev sib txuas tshwm sim nyob rau hauv ib qho chaw hauv Circuit Court vim tsis raug xaim lossis luv Circuit Court. Tab sis qhib Circuit Court kaw kuj tuaj yeem tswj tau txhob txwm los yog lub hom phiaj los ntawm cov keyboards, fuses, thiab circuit breakers.

Yog li, qhov pib qhib hluav taws xob tuaj yeem raug kaw vim tsis raug xaim, luv luv Circuit Court, hloov tau qhib, lub fuse tshiab raug teeb tsa, lossis lub tshuab hluav taws xob tau qhib.

Yuav ua li cas thaum lub Circuit Court qhib los yog kaw

Kuv yuav qhia koj tias yuav ua li cas tshwm sim nyob rau hauv rooj plaub ntawm lub teeb pom kev zoo nrog ib lossis ob lub keyboards.

Ib leeg Derailleur Chain

Ib qho yooj yim Circuit Court nrog ib qho kev hloov pauv tsuas yog txuas nrog hauv cov khoom siv nrog lub nra, xws li lub teeb pom kev zoo.

Nyob rau hauv cov ntaub ntawv no, lub lag luam ntawm lub teeb lub teeb yog kiag li nyob ntawm no mus. Yog tias nws kaw (on), ces lub teeb yuav qhib, thiab yog tias nws qhib (tawm), lub teeb kuj yuav raug kaw.

Qhov kev npaj ntawm circuits no muaj ntau nyob rau hauv high-power circuits thaum peb yuav tsum tau kom paub tseeb tias ib tug ntaus ntawv xws li ib tug twj tso kua mis lub cev muaj zog yog tswj los ntawm ib tug tib hloov.

Circuit Court nrog ob lub keyboards

Cov txheej txheem ob-tus yuam sij kuj muaj cov kev siv tswv yim.

Yuav ua li cas thaum lub Circuit Court qhib los yog kaw nyob ntawm seb lub Circuit Court puas tiav los yog tsis tiav thiab seb nws yog ib tug series los yog parallel circuit.

Xav txog ib lub voj voog nrog ob lub keyboards nyob rau sab saum toj thiab hauv qab ntawm cov ntaiv kom tswj tau ib lub teeb. Cov lus hauv qab no tham txog tag nrho plaub txoj hauv kev rau txhua hom schema.

Raws li koj tuaj yeem pom los ntawm cov lus saum toj no, ob lub keyboards yuav tsum tau qhib (lossis kaw) hauv series kom lub teeb tuaj. Yog tias ib qho ntawm lawv raug kaw lossis ob qho tib si tawm, lub teeb yuav raug kaw vim nws yuav qhib lub voj voog.

Nyob rau hauv ib qho kev sib txuas, tsuas yog ib qho ntawm cov keyboards yuav tsum nyob rau (lossis kaw) kom lub teeb tuaj. Lub teeb yuav tsuas tua yog tias ob lub qhov hluav taws xob raug kaw, uas yuav qhib lub voj voog tag nrho.

Rau cov ntaiv, koj yuav tsum tuaj yeem tua lub teeb nrog rau sab saum toj lossis hauv qab hloov, yog li koj tuaj yeem pom tias qhov kev sib txuas yog qhov tsim nyog tshaj plaws.

hluav taws xob txoj kev xav

Peb tuaj yeem saib qhov sib txawv kom nkag siab qhov sib txawv ntawm lub kaw lus kaw thiab qhib Circuit Court kom ntxaws ntxiv. Cov kev sib txawv no muaj nyob rau hauv cov lus hauv qab no.

Qhov qhib Circuit Court yog nyob rau hauv lub xeev off vim hais tias lub Circuit Court yog qhib los yog tsis tiav, thaum lub kaw Circuit Court yog nyob rau hauv lub off state vim hais tias lub Circuit Court yog tas mus li los yog kaw. Ib qho qhib Circuit Court tsis tso cai rau tam sim no ntws, thiab tsis muaj kev hloov hluav taws xob lossis hloov hluav taws xob hluav taws xob. Nyob rau hauv sib piv, ib tug qhib Circuit Court cia tam sim no ntws. Yog li ntawd, electrons thiab hluav taws xob hluav taws xob kuj raug xa mus.

Qhov voltage (los yog muaj peev xwm sib txawv) ntawm qhov tawg hauv qhov qhib Circuit Court yuav sib npaug rau cov khoom siv hluav taws xob thiab suav tias tsis yog xoom, tab sis nyob rau hauv lub kaw lus kaw nws yuav luag xoom.

Peb kuj tuaj yeem qhia lwm qhov sib txawv ntawm kev tawm tsam siv Ohm Txoj Cai (V = IR). Qhov qhib Circuit Court yuav tsis kawg vim xoom tam sim no (I = 0), tab sis nyob rau hauv lub kaw Circuit Court nws yuav nyob ntawm tus nqi tam sim no (R = V / I).

Yam	Qhib Circuit Court	kaw Circuit Court
cheeb tsam	Qhib los yog OFF	Kaw lossis tawm
chain txoj	tawg, cuam tshuam los yog tsis tiav	txuas ntxiv lossis ua tiav
Tam sim no	Tsis muaj xov tam sim no	Cov xov tam sim no
xwm	Tsis muaj electron hloov	hloov hluav taws xob
Zog	Hluav taws xob tsis kis	Hluav taws xob hluav taws xob kis tau
Voltage (PD) ntawm breaker/switch	Sib npaug rau cov khoom siv hluav taws xob (tsis yog xoom)	Yuav luag xoom
Txoj hauj lwm	Tsis kawg	Sib npaug V/I
Cim

Yog li, ib lub voj voog ua tiav lossis ua haujlwm tsuas yog kaw, tsis qhib.

Ntxiv rau txoj kev ua tiav thiab tsis muaj kev cuam tshuam tam sim no, lub kaw lus kaw yuav tsum muaj cov hauv qab no:

• Ib qho khoom siv hluav taws xob, xws li roj teeb.
• Txoj kev yog ua los ntawm ib tug neeg xyuas pib xws li tooj liab hlau.
• Ib qho load hauv ib lub voj voog, xws li lub teeb.

Yog tias tag nrho cov xwm txheej no tau ua tiav, cov khoom siv hluav taws xob yuav ntws ywj pheej thoob plaws hauv Circuit Court.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.

• Yuav ua li cas ntxiv ib qho nruab nrab xaim rau lub teeb hloov uas twb muaj lawm
• Yuav ua li cas txuas lub teeb lub teeb
• Yuav ua li cas kuaj lub Circuit Court breaker nrog multimeter
