Ua rau ntawm lub qhov rais fais fab ua haujlwm tsis zoo
Qhov rai malfunctions yog feem ntau ua rau los ntawm ib tug faulty qhov rai regulator (tseem hu ua a qhov rai khiav), los yog lub cev muaj zog tawg, cable pulley los yog qhov rai hloov. Ib qho teeb meem tas mus li yog thaum lub qhov rais tsis ua ua haujlwm dua. Overheated motors feem ntau ua rau Cov teeb meem tsis sib xws, Benet hais
Ua kom pom qhov no, lub fuse puas tuaj yeem nres lub qhov rais tsis ua haujlwm?
Tshuab Fuse Ib cua tshuab fuse yog ib qho laj thawj ntawm a qhov rai raug daig. Yog ib qhov rai yuav tsis nce mus, thiab lwm yam peb qhov rais ntawm koj lub tsheb tau ntsib ib yam teeb meem, ces ib tug tshuab fuse zoo li yuav.
Ib yam li ntawd, lub qhov rais fais fab puas muaj fuses? Feem ntau lub qhov rais fais fab mechanism yog yooj yim heev. Muaj ib qho yooj yim regulator mechanism, feem ntau zoo ib yam li lub tshuab siv nyob rau hauv lub vaj-ntau yam tes-cranked qhov rais . Hnub nyoog thiab ob peb nplaum qhov rai channels yuav pop a fuse.
Ua raws li qhov no, kuv yuav ua li cas thiaj paub yog tias kuv lub qhov rais fais fab hloov tsis zoo?
Txhawm rau kuaj lub qhov rais hloov koj yuav tsum siv lub voltmeter thiab ohmmeter
- Tshem lub qhov rais faulty hloov ntawm lub qhov rooj.
- Tig qhov hloov mus rau txoj haujlwm "qhib".
- Txuas lub voltmeter mus rau qhov hloov pauv thiab kuaj xyuas seb puas muaj 12 volts los ntawm lub davhlau ya nyob twg 4 mus rau hauv av thiab los ntawm lub davhlau ya nyob twg 5 mus rau hauv av.
Koj sim li cas lub qhov rais fais fab hloov?
Txuas cov coj ntawm koj lub voltmeter mus rau ob lub terminals ntawm lub connector. Tig tus yuam sij rau txoj haujlwm "on" thiab toggle qhov qhov rais hloov nce thiab nqis. Yog tias hloov yog qhov zoo, koj yuav pom qhov kev nyeem ntawv hloov pauv ntawm qhov ntxiv-12 volts rau rho tawm-12 volts. Qhov ntawd txhais tau tias qhov teeb meem yog lub cev muaj zog / regulator.

Txoj kev qhib () qhib lub qhov rais browser tshiab, lossis lub tab tshiab, nyob ntawm koj qhov browser nqis thiab qhov ntsuas qhov tseem ceeb
Kuv yuav tsum nrhiav dab tsi thaum yuav lub khoos phis tawj fais fab?
Cov kauj ruam Txiav txim siab wattage koj xav tau. Siv lub tshuab xam zauv PSU lub vev xaib lossis software los pab txiav txim siab koj cov cai. Tshawb nrhiav cov connectors uas koj xav tau. Saib rau PSUs nrog cov qhab nia ua tau zoo. Txiav txim siab qhov robustness ntawm PSU. Tshawb xyuas tus naj npawb ntawm txoj kab tsheb ciav hlau. Tau txais modular PSU. Sib piv cov amperage ntawm txhua qhov voltage
Dab tsi ntawm cov fais fab ntsaws yog siv nyob rau hauv cov ntaub ntawv chaw?
Cov hom ntsaws ntau tshaj plaws hauv cov chaw khaws ntaub ntawv yog C-13 thiab C-19 connectors (saib daim duab 1) raws li tau hais los ntawm IEC 60320. C-13 connectors feem ntau pom ntawm cov servers thiab cov keyboards me me, thaum cov hniav thiab cov khoom siv sib txuas loj dua siv C. -19 ntsaws vim nws muaj peev xwm nqa tam sim no ntau dua
Class 2 fais fab mov siv rau dab tsi?
Chav Kawm 2 yog ib qho kev faib tawm hais txog NEC - National Electric Code. Txhawm rau kom tsis txhob muaj cov kab hluav taws xob kub dhau vim muaj qhov hluav taws xob ntau dhau thiab hluav taws xob poob siab, cov khoom siv hluav taws xob raug txwv rau 60VDC lossis 100VA, (100W thaum siv nrog AC-DC fais fab mov)
Koj txuas fais fab BI li cas rau lub txim?
Tua tawm Power BI Desktop, nyem Tau Cov Ntaub Ntawv hauv toolbar, thiab nyem Ntxiv…. Hauv Cov Ntaub Ntawv Sib Tham, nrhiav thiab xaiv Spark connector. Nyem Txuas. Ntawm Spark dialog, teeb tsa koj qhov kev sib txuas ua ke
