Yuav sim kuaj ib lub capacitor li cas?

Kuaj lub capacitor yog cov txheej txheem tseem ceeb uas ua kom nws cov haujlwm zoo thiab kev nyab xeeb. Raws li tus chaw xa khoom, peb nkag siab qhov tseem ceeb ntawm kev xeem kom tau raws li cov neeg yuav khoom sib txawv. Nyob rau hauv no blog ncej, peb yuav tshawb txog ntau txoj hauv kev thiab cov txheej txheem rau kev kuaj mob capacitors, ua rau lawv qhov tseem ceeb hauv kev tswj cov hluav taws xob siab - lub tshuab hluav taws xob siab.

 

TIVOG SIS TAU POLPTORITORS:

Ua ntej yuav hauv cov txheej txheem ntsuas, nws yog qhov tseem ceeb uas yuav muaj kev nkag siab yooj yim ntawm lub capacitor yog dab tsi. Lub capacitor yog hluav taws xob hluav taws xob uas khaws cia thiab tso hluav taws xob hluav taws xob. Nws muaj ob daim phiaj ua haujlwm sib cais los ntawm cov ntaub ntawv insulating hu ua dielectric. Peev tau siv cov kev siv hluav taws xob ntau, suav nrog kev txhim kho lub zog, lim, txuas, thiab sijhawm ua ke.

 

Vim li cas thiaj thiaj li mus sim capacitors?

Muaj ntau cov laj thawj yog vim li cas thiaj li sim siv lub peev xwm capacitors yog qhov tsim nyog. Firstly, nyob rau lub sijhawm, Capacitors tuaj yeem txwv tsis yog vim muaj cua sov, kev ntxhov siab, thiab kev laus. Tus kws lij choj tuaj yeem ua rau cov khoom siv tsis zoo, txo qis, thiab muaj kev nyab xeeb nyab xeeb. Qhov thib ob, thaum lub sijhawm tsim kev tsim khoom, kev xeem pab kom txheeb xyuas qhov tsis xws luag capacitors ua ntej lawv tau teeb hluav taws xob. Qhov no ua kom ntseeg tau tias tsuas yog siab - cov cheebtsam zoo ncav cuag kev ua lag luam.

 

Kev Ntsuam Xyuas Pom:

Thawj kauj ruam hauv kev sim lub capacitor yog kev tshuaj xyuas pom. Qhov txheej txheem yooj yim no tseem tau qhia tau pom tseeb ntawm kev puas tsuaj lossis tsis zoo. Saib rau lub cev cov cim xws li bulging, xau, lossis cov neeg tawg. Lub capacitor bulget yog feem ntau qhia txog lub siab sab hauv tsim - nce, uas tuaj yeem tshwm sim los ntawm kev kub siab lossis ntau dhau. Leaking electrolyte yog lwm qhov teeb meem loj, vim nws tuaj yeem ua rau lwm cov khoom siv hauv Circuit Court. Ib qho ntxiv, tshawb xyuas cov cim kev xeb ntawm cov terminals, uas tuaj yeem cuam tshuam rau kev sib txuas hluav taws xob.

 

Kev Ntsuas Ntsuas:

Ib qho ntawm cov kev tshwm sim feem ntau los sim lub capacitor yog los ntawm kev ntsuas nws lub peev xwm. Capacitance yog lub peev xwm ntawm lub capacitor los khaws cov hluav taws xob hluav taws xob thiab ntsuas hauv cov chaw deb (f). Txhawm rau ntsuas qhov muaj peev xwm capacitance, koj yuav tsum muaj lub peev xwm ntsuas hluav taws xob. Ntawm no yog yuav ua li cas: 1.Tso lub capacitor: Ua ntej coj ib qho kev ntsuas, nco ntsoov tias cov capator yog tso tawm tag nrho. Qhov no tuaj yeem ua tiav los ntawm kev siv lub resistor mus luv - Circuit Coapitor cov chaw. 2.Teeb tsa lub scchi capaptance meter: Xaiv cov khoom haum tsim nyog nyob rau ntawm capatoreter meter raws li cov kev xav tau ntawm lub peev xwm capacitance ntawm lub capacitor. 3.Txuas Lub Meter: Txuas cov ua rau cov meter capaptance meter rau cov kev sib cav ntawm lub capacitor. Nco ntsoov tias cov kev sib txuas muaj kev ruaj ntseg. 4.Coj ntsuas ntsuas: Nyeem cov nqi capacitance tshwm sim rau ntawm lub meter. Sib piv cov nqi no nrog rated capacitance ntawm lub capacitor. Ib qho kev sib txawv tseem ceeb los ntawm tus nqi rated yuav qhia tau tias muaj peev xwm txhaum cai.

 

 

ESR (sib npaug series tiv taus) kev ntsuas:

Ntxiv nrog rau kev muaj peev xwm, qhov sib npaug series tiv (ESR) ntawm lub caport yog ib qho tseem ceeb ntsuas ntsuas. ESR sawv cev rau cov kev tiv thaiv uas muaj txiaj ntsig zoo nrog lub capacitor. Ib qho siab ESR tuaj yeem ua rau lub zog ua kom muaj zog, overheating, thiab txo cov peev txheem kev ua tau zoo. Txhawm rau ntsuas ESR, koj yuav xav tau ib lub ESR METTER. Cov txheej txheem zoo ib yam li kev ntsuas ntsuas hluav taws xob: 1.Tso lub capacitor: Raws li nrog lub peev xwm ntsuas hluav taws xob, kom lub capactrator raug tso tawm ua ntej kev sim. 2.Teeb tsa ESR 'meter': Xaiv cov kev tsim nyog ntau ntawm ESR meter. 3.Txuas Lub Meter: Txuas lub ESR ntsuas ua rau lub capacitorals lub terminals. 4.Coj ntsuas ntsuas: Nyeem tus nqi ESR ntawm lub ntsuas dej. Piv nrog nws nrog cov kev pom zoo estr ntau rau cov capacitor tshwj xeeb.

 

Rwb thaiv tsev Kuj:

Rwb thaiv tsev tiv thaiv yog siv los tshawb xyuas qhov tseeb ntawm cov ntaub ntawv dielectric hauv lub capacitor. Lub rwb thaiv tsev tsis kam tuaj yeem qhia tau tias muaj kev rhuav tshem rau hauv dielectric, uas tuaj yeem ua rau to taub dej tam sim no thiab capacitor tsis ua haujlwm thiab muaj peev xwm. Txhawm rau ua rwb thaiv tsev tsis kam kuaj, koj yuav tau txais ib mitohmeter. Ntawm no yog cov txheej txheem: 1.Tso lub capacitor: Tus capacitor kom meej. 2.Teeb tsa lub melohmeter: Xaiv cov voltage uas tsim nyog nyob rau moeghmeter. 3.Txuas lub moegohmeter: Txuas ib txoj kev coj ntawm MEEGHIHMETER rau ib lub davhlau ya nyob twg ntawm lub capacitor thiab lwm yam ua rau lub capacitor cov ntaub ntawv lossis lwm lub davhlau ya nyob twg (nyob ntawm qhov yuav tsum tau ua). 4.Coj ntsuas ntsuas: Nyeem cov rwb thaiv tsev tsis kam lees tus nqi ntawm moegohmeter. Ib lub rwb thaiv tsev tsis kam tiv thaiv tus nqi yuav qhia tau ib qho teeb meem nrog lub catactrator's dielectric.

 

Kuaj sib txawv hom kev muaj zog:

Peb muab ntau lub peev xwm, xws li lub BSMJ series cylindrical tsawg voltage parallel capacitance, BSMJ Series tus kheej - kho qis qis voltage shunt capacitors, thiab BSMJR LUB ROOJ PEEV Cov Hluav Taws Xob Rau Arrgerged Arc RauvCov. Txhua hom capacitor kuj yuav xav tau kev txiav txim siab txog kev xeem.

Piv txwv li, tus kheej - kho lub zog muaj peev xwm capacitors, zoo li BSMJ series, yog tsim los kho cov hnub nyoog dielectric me me. Thaum kuaj cov cus paj no, ntxiv rau cov qauv kev sim, them sai sai rau lawv tus kheej - kho cov yam ntxwv. Kuaj xyuas yog tias lub capacitor tuaj yeem muaj rov qab los ntawm cov sor volarage me me uas tsis muaj kev cuam tshuam tseem ceeb hauv kev ua tau zoo.

Lub zog hluav taws xob, xws li BSMJR lub zog hluav taws xob rau submerrerged arc rauv, feem ntau siv nyob rau hauv siab - cov kev siv fais fab. Cov capacitors yuav tsum tau kuaj nyob rau hauv siab - voltage thiab high - tam sim no cov xwm txheej kom ntseeg tau tias lawv txoj kev ntseeg tau. Cov cuab yeej ntsuas tshwj xeeb yuav tsum tau sim ua kom muaj kev ua haujlwm tiag tiag.
