Yuav ua li cas tso lub capacitor

Koj paub Yuav ua li cas tso tawm lub capacitor? Yog tsis yog, tsis txhob txhawj!

Nov yog cov lus qhia kawg rau kev tso tawm cov capacitors. Peb yuav piav qhia txog ntau txoj hauv kev uas koj tuaj yeem siv los tso tawm lub capacitor. nyab xeeb ib kauj ruam.

Lub capacitor yog dab tsi thiab nws yog dab tsi?

Lub capacitor yog ib qho khoom siv rau khaws cov hluav taws xob hluav taws xob. Nws ua qhov no los ntawm kev tsim hluav taws xob ntawm ob daim hlau. Thaum voltage yog siv, nws tsub lub capacitor.

Lub capacitance ntawm lub capacitor yog ib qho kev ntsuas ntawm tus nqi uas nws tuaj yeem khaws thiab feem ntau yog hais hauv farads.

Capacitors ua haujlwm zoo li cov roj teeb uas tuaj yeem siv tau hauv AC circuits. Lawv ua lawv txoj haujlwm ntawm kev khaws cov hluav taws xob hluav taws xob thiab xa mus rau lwm qhov hauv Circuit Court.

Vim li cas capacitors yuav tsum tau tso tawm?

Raws li peb tau hais ua ntej, capacitors khaws hluav taws xob thiab tuaj yeem ua rau koj poob siab yog tias koj kov lawv thaum lawv tseem raug them. Yog li ntawd, nws yog ib qho tseem ceeb kom tso lawv tawm ua ntej kov lawv.

Lawv tuaj yeem tuav qhov tam sim no hauv lawv tus kheej mus txog li ob peb feeb tom qab qhov tam sim no nres ntws los ntawm Circuit Court. Yog li ntawd, peb yuav tsum tso lawv tawm ua ntej ua haujlwm.

Cov capacitors twg raug suav tias muaj kev nyab xeeb?

Tsis muaj lus teb rau lo lus nug no. Txhua lub capacitor tuaj yeem ua mob rau koj ntau dua lossis tsawg dua. Tab sis cov capacitors 50 volts tsis tuaj yeem ua rau tam sim no ntws los ntawm lub cev thiab ua rau tuag taus.

Cov capacitors tsawg dua 50 volts feem ntau ua rau kub hnyiab, hluav taws xob me me, thiab qhov hnov ​​​​tsw me ntsis hauv cov ntiv tes. Peb xav tias lawv muaj kev nyab xeeb.

Nco ntsoov tias tsuas yog khoob capacitors xwb 100% kev nyab xeeb.

Kev ceev faj ua ntej tso tawm lub capacitor

1. Disconnect tus capacitor los ntawm lub hwj chim qhov chaw.

Ua ntej peb tuaj yeem piav qhia yuav ua li cas tso tawm lub capacitor, peb yuav tsum xub tshem lub hwj chim ntawm nws.

- Cov cuab yeej hauv tsev tsuas yog tshem tawm ntawm lub qhov hluav taws xob.

-Yog tias nws nyob hauv lub tsheb, ces koj yuav tsum tau txiav cov xov hlau ntawm lub tsheb roj teeb, uas txuas nrog + thiab - terminals.

- Ib qho khoom siv uas txuas nrog lub roj teeb sab nraud lossis muaj nws tus kheej lub zog yuav tsum raug muab tua thiab cov kab hluav taws xob yuav tsum raug txiav.

2. Hnav cov iav tiv thaiv

Muaj ntau qhov laj thawj vim li cas nws tseem ceeb heev kom muaj cov cuab yeej tiv thaiv thaum tso tawm cov capacitors.

Ib qho laj thawj yog vim li cas capacitors tuaj yeem khaws ntau lub zog thiab thaum lawv pib tawm lawv tuaj yeem pov tawm cov txim.

Lwm qhov laj thawj yog tias cov capacitors tuaj yeem ua rau hluav taws xob poob siab thaum lawv cov hlau sib cuag nrog cov tawv nqaij.

Cov neeg feem coob pom tias nws lom zem los hnav cov iav tiv thaiv, tab sis thaum lawv raug mob los ntawm hluav taws xob poob lossis hluav taws xob, lawv hloov siab.

Cov iav tiv thaiv xws li tsom iav thiab hnab looj tes tuaj yeem pab tiv thaiv koj ntawm cov kev pheej hmoo no.

3. Ib puag ncig nyab xeeb

Nco ntsoov tias tsis muaj cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob nyob ze koj thaum koj tso lub capacitor.

Tshem tawm nrog lub hau ntswj

1. Tua lub hwj chim

Thaum ua hauj lwm nrog capacitors, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tua lub hwj chim ua ntej tso tawm. Qhov no yuav pab tiv thaiv kev raug mob thiab xwm txheej. Capacitors tuaj yeem khaws ntau lub zog.

2. Nrhiav lub capacitor ntawm ib qho khoom siv hluav taws xob

Raws li txoj cai, capacitors nyob ze ntawm lub hwj chim qhov chaw, raws li lawv yog lub luag hauj lwm rau khaws cia lub zog thiab tswj tam sim no. Yog tias koj muaj teeb meem nrhiav lub capacitor, xa mus rau daim duab kos duab lossis phau ntawv siv rau koj lub cuab yeej.

3. Siv lub capacitor thiab nrhiav qhov zoo thiab tsis zoo terminals.

Nqa lub capacitor los ntawm lub cev tsis tas kov ob txhais ceg (terminals), siv hnab looj tes. Cov hlau sib txuas yog qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob.

4. Siv ib tug insulated screwdriver los txuas cov terminals ua ke.

Thaum tso tawm lub capacitor, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov ntsia hlau insulated kom tsis txhob muaj kev sib cuag nrog cov neeg nyob.

Ua ntej txheeb xyuas qhov zoo thiab tsis zoo terminals ntawm lub capacitor. Tom qab ntawd txuas qhov zoo thiab tsis zoo terminals nrog ib tug insulated screwdriver. Tuav lub hau ntsaws rau hauv qhov chaw rau ob peb feeb kom txog thaum lub capacitor tawm.

Tshem tawm lub capacitor tuaj yeem ua rau lub txim taws lossis lub suab me me. Qhov no yog qhov qub thiab yuav tsum tsis txhob ntshai koj.

5.  Tshem lub hau ntswj ntawm lub capacitor leads.

Koj tuaj yeem rov ua cov kauj ruam dhau los kom paub tseeb tias nws khoob. Tom qab ntawd tsuas yog tshem lub hau ntswj ntawm lub terminals.

6. Txuas multimeter los ntsuas qhov voltage

Siv ib tug multimeter los ntsuas lub capacitor voltage. Txuas kev sojntsuam thiab kev sib cuag hlau. Kev sib txuas lus (polarity) tsis tseem ceeb.

Yog tias koj tau txais tus nqi siab tshaj xoom, lub capacitor tsis tau tso tawm tag nrho thiab cov txheej txheem yuav tsum tau rov ua dua ob peb zaug kom ntseeg tau tias lub capacitor tau tawm tag nrho.

Pen Discharge

Txhawm rau tso lub capacitor, koj tuaj yeem siv tus cwj mem kom luv ob daim hlau. Qhov no yuav tsim ib lub txim uas yuav sai sai dissipate tus nqi. Nco ntsoov siv ceev faj thaum tso tawm cov capacitors vim tias lawv tuaj yeem khaws ntau lub zog.

Qhov no yog txoj kev yooj yim thiab ceev tshaj plaws. Cov cuab yeej tso tawm muaj qhov muaj zog tiv thaiv siab, uas tso cai rau koj tawm sai sai.

Tshem tawm nrog lub teeb pom kev zoo

Qhov thib peb yog siv lub teeb. Yog tias koj tsis muaj lub cuab yeej me me lossis lub hau ntswj hauv tsev, koj tuaj yeem siv lub teeb pom kev zoo.

1. Koj yuav tsum nqa ib lub teeb, uas txuas nrog lub qhov (socket) nrog cov xov hlau.
2. Txuas ib lub xaim mus rau qhov zoo davhlau ya nyob twg thiab lwm lub xaim mus rau lub davhlau ya nyob twg tsis zoo. Lub teeb yuav pib teeb, thiab thaum nws tawm mus, nws yuav txhais tau hais tias lub capacitor raug tso tawm.

Qhov kom zoo dua ntawm lub teeb pom kev zoo dua lwm cov cuab yeej yog tias nws muaj qhov taw qhia lub teeb uas qhia tau hais tias thaum lub capacitor tawm tag nrho.

Discharge nrog resistor

1. Xyuas kom tseeb tias lub capacitor yog disconnected thiab tsis powered.
2. Txuas ib tug loj resistor hla lub capacitor terminals.
3. Kov qhov kawg ntawm cov resistor mus rau cov hlau hu ntawm lub capacitor.
4. Tos kom txog thaum lub capacitor tawm.
5. Disconnect tus resistor los ntawm lub capacitor.
6. Txuas lub capacitor thiab tig nws.

Lub resistor tiv thaiv ib tug loj inrush tam sim no los ntawm lub capacitor, uas yuav ua rau nws puas. Los ntawm maj mam tso lub capacitor nrog lub resistor, koj tuaj yeem zam cov teeb meem tshwm sim.
