Dab tsi yuav tsum tau them sai sai rau thaum siv electrolytic capacitor?

Dab tsi yuav tsum tau them sai sai rau thaum siv electrolytic capacitor, feem ntau suav nrog kaum cov ntsiab lus hauv qab no:
1. Lub DC electrolytic capacitor muaj polarity: lub polarity cim ntawm lub capacitor yog nyob rau hauv lub hauv paus ntawm lub capacitor kom tsis txhob Circuit Court luv luv los yog capacitor puas vim polarity. Yog tias koj xav siv lub tshuab hluav taws xob bipolar electrolytic capacitor uas tsis paub meej polarity lossis ntawm qhov tsis paub tseeb, thov siv lub tshuab hluav taws xob bipolar electrolytic capacitor. Nco ntsoov tias DC electrolytic capacitor tsis tuaj yeem siv rau AC.
2. Tsis txhob siv qhov hluav taws xob ntau dua li qhov ntsuas hluav taws xob: Yog tias qhov hluav taws xob ntau dua li qhov ntsuas hluav taws xob, qhov hluav taws xob xau yuav nce ntxiv thiab yuav ua rau lub capacitor puas. Qhov pom zoo ua haujlwm voltage yog 70 feem pua ​​-80 feem pua ​​​​ntawm qhov ntsuas hluav taws xob, thiab siv lub capacitor ntawm qhov pom zoo ua haujlwm voltage yuav txuas ntxiv lub neej ntawm lub capacitor.
3. Tsis txhob cia cov ripple tam sim no dhau los ntawm lub capacitor: Kev siv ripple tam sim no ntau tshaj qhov ntsuas tus nqi tuaj yeem ua rau lub cev capacitor overheat, txo lub peev xwm, thiab ua rau lub capacitor lub neej puas. Lub ncov tus nqi ntawm cov ntaub ntawv ripple voltage yuav tsum tsawg tshaj li qhov ntsuas ua haujlwm voltage.
4. Qhov ntsuas kub ntawm qhov chaw ua haujlwm yog qhov tsim nyog: cov yam ntxwv ntawm lub capacitor sib txawv nrog qhov kub thiab txias ua haujlwm. Ntawm qhov kub thiab txias, qhov muaj peev xwm thiab cov dej ntws tawm tam sim no nce, thiab qhov poob qis; Thaum tsis tshua muaj kub, muaj peev xwm thiab cov dej ntws tam sim no txo ​​qis thiab poob nce. Capacitors siv nyob rau hauv qhov kub thiab txias yuav ua rau lawv lub neej ntev. Raws li kev txheeb cais, rau txhua txhua 10 degree txo qis hauv ambient kub, nws lub neej kev pab cuam ob npaug.
5. Txheeb xyuas qhov ua haujlwm zaus: lub peev xwm ntawm electrolytic capacitor feem ntau yog ntsuas ntawm qhov zaus ntawm 100 ~ 120Hz. Txawm li cas los xij, lub peev xwm yuav txo qis nrog kev nce ntau zaus, kev poob yuav nce ntxiv nrog kev nce ntau zaus, thiab qhov kub ntawm ib puag ncig yuav nce ntxiv.
6. Lub sij hawm ntev cia ntawm cov capacitors: Ntxiv cov ntsuas DC voltage ua ntej siv rau lub sijhawm ntev tsis muaj feem cuam tshuam rau lub peev xwm thiab poob ntawm lub capacitor. Txawm li cas los xij, nws tuaj yeem ua kom cov dej ntws tawm tam sim no ntawm lub capacitor thiab txo nws cov hluav taws xob tiv thaiv. Rau cov capacitors khaws cia rau lub sijhawm ntev, DC voltage yuav tsum tau maj mam siv rau qhov ntsuas hluav taws xob ua ntej siv.
7. Lub plhaub ntawm lub electrolytic capacitor tsis yog insulated los ntawm cathode kawg: lub plhaub ntawm lub electrolytic capacitor txuas nrog cathode los ntawm electrolyte. Yog hais tias lub plhaub ntawm lub capacitor yuav tsum tau insulated los ntawm txoj kab, kev ntsuas rwb thaiv tsev yuav tsum tau coj mus rau qhov chaw ntawm lub capacitor.
8. Tsis txhob siv lub zog ntau dhau rau lub davhlau ya nyob twg lossis cov hlau lead ntawm electrolytic capacitor: yog tias muaj zog ntau dhau mus rau lub davhlau ya nyob twg los yog txhuas, qhov nro yuav ua rau sab hauv ntawm lub capacitor, uas yuav ua rau cov hlau lead tawg lossis qhov sib cais ntawm lub davhlau ya nyob twg, uas nyob rau hauv lem yuav ua rau kev puas tsuaj rau lub internal kev twb kev txuas ntawm lub capacitor, uas ua rau luv luv Circuit Court, qhib Circuit Court los yog tsub kom qhov hluav taws xob tam sim no nyob rau hauv lub capacitor, ua rau lub capacitor puas. Tsis txhob quab yuam co lub capacitor thaum soldering rau hauv Circuit Court board.
9. Ua tib zoo saib xyuas qhov kub thiab txias thaum lub sij hawm vuam: cov hlau soldering yuav tsum tau khaws cia ntawm qhov deb ntawm lub tes tsho yas ntawm lub capacitor. Thaum lub capacitor tso rau hauv lub tank solder, nws raug nquahu kom khaws qhov kub ntawm 260C tsis pub ntau tshaj 10 vib nas this kom tsis txhob muaj kev puas tsuaj rau lub capacitor. Lub tes tsho yas yuav rupture los yog shrinkage vim lub sij hawm vuam ntau dhau los yog kub.
10. Layout ntawm qhov ntawm cov ntawv luam tawm Circuit Board: Thaum tsim cov ntawv luam tawm Circuit Court boards, lub installation qhov sib nrug yuav tsum sib npaug ntawm cov txhuas qhov sib txawv. Thaum qhov sib nrug ntawm qhov sib txawv ntau dua lossis tsawg dua qhov sib txawv ntawm cov hlau lead, kev ntxhov siab yuav raug siv rau cov hlau lead thaum txhim kho cov capacitors, uas yuav ua rau luv luv Circuit Court puas, thiab muaj zog to tam sim no.
