Kev ceev faj rau kev tswj xyuas hluav taws xob hauv Circuit Court
1. Ntxiv kev rho tawm transformer
Cov khoom siv hluav taws xob hloov pauv feem ntau yog cov khoom siv hluav taws xob sib txuas sib txuas. Rau cov khoom siv hluav taws xob sib txuas sib txuas, txawm hais tias lub rooj tsav xwm hauv Circuit Court qhov chaw thauj khoom yog lub phaj txias hauv qab, lub hauv paus tseem ceeb ntawm kev hloov hluav taws xob hloov hluav taws xob tseem yog lub phaj kub hauv qab. Yog li, yog tias tsis muaj kev sib cais transformer ntxiv, qhov hloov pauv tsis tuaj yeem ntsuas nrog oscilloscope. Txhua lub voj voog ua ntej thawj sab ntawm lub transformer, txwv tsis pub, yuav tsis tsuas yog cov ntaub ntawv oscilloscope yuav electrified, ua phem rau tus neeg, tab sis kuj hlawv tawm lub hwj chim mov. Thaum ntsuas qhov voltage nrog lub multimeter, ib qho kev sib cais transformer yuav tsis ntxiv.
2. tsis txhob poob hluav taws xob
Thaum kho cov khoom siv hluav taws xob hloov pauv, kev siv lub tshuab hluav taws xob sib cais tsis tuaj yeem lav 100 feem pua kev nyab xeeb. Qhov tsim nyog thiab txaus rau hluav taws xob poob siab yog qhov muaj peev xwm sib txawv tshaj qhov muaj kev nyab xeeb ntawm ob lossis ntau tus neeg xyuas pib hauv kev sib cuag nrog lub cev, thiab muaj qee qhov kev siv. Hluav taws xob ntws los ntawm lub cev. Kev sib cais transformer tuaj yeem tshem tawm qhov sib txawv ntawm qhov kub hauv av thiab daim phiaj hluav taws xob, thiab rau qee yam tuaj yeem tiv thaiv hluav taws xob poob siab. Tab sis nws tsis tuaj yeem tshem tawm qhov muaj peev xwm sib txawv ntawm cov ntsiab lus hauv Circuit Court, uas yog hais tias, yog tias cov neeg ua haujlwm saib xyuas kov cov khoom uas muaj peev xwm sib txawv hauv kev hloov hluav taws xob hloov hluav taws xob nrog ob txhais tes tib lub sijhawm, nws tseem yuav ua rau hluav taws xob poob. . Yog li ntawd, thaum kho, yog tias cov neeg ua haujlwm saib xyuas yuav tsum ua haujlwm nrog hluav taws xob, lawv yuav tsum ua ntej insulate lawv lub cev los ntawm hauv av kom ntseeg tau, xws li zaum ntawm lub rooj zaum ntoo, nqis rau ntawm lub rooj tsavxwm qhuav lossis cov ntaub ntawv insulating xws li ntim npuas hauv qab lawv txhais taw; Tau txais tus cwj pwm ntawm kev khiav hauj lwm nrog ib txhais tes, tiv thaiv kev tsim hluav taws xob los ntawm lwm qhov tes lossis lwm qhov ntawm lub cev thaum nws tsim nyog los kov qhov chaw nyob, thiab lwm yam, yog txhua yam kev ntsuas zoo kom tsis txhob muaj hluav taws xob poob siab.
3. Xaiv lub peev xwm siv tau
Txhawm rau ntsuas qhov voltage ntawm lub hwj chim Circuit Court, nws yog ib qho tsim nyog yuav tau xaiv qhov muaj peev xwm siv tau. Hauv av ua ntej thawj sab ntawm qhov hloov pauv hloov pauv yog qhov kub hauv av, thiab hauv av tom qab thawj sab ntawm qhov hloov pauv hloov pauv yog qhov av txias. Ob leeg tsis yog equipotential. Yog li ntawd, thaum ntsuas qhov voltage ntawm lub hauv paus Circuit Court ntawm lub switching transformer, siv cov av kub raws li qhov taw tes siv, uas yog, txuas tus cwj mem tsis zoo ntawm multimeter mus rau hauv av kub; Thaum ntsuas qhov thib ob Circuit Court (load Circuit Court) ntawm qhov hloov pauv hloov pauv, siv cov av txias raws li qhov taw qhia siv, uas yog, txuas lub multimeter Lub ntsuas qhov tsis zoo yog txuas nrog hauv av txias.
4. Thaum lub hwj chim mov tsis oscillate, lub voltage hla lub loj lim capacitor yuav tsum tau tso tawm.
Txhawm rau kho cov khoom siv fais fab uas tsis muaj qhov tso tawm, tig nws thiab tom qab ntawd tua lub hwj chim. Txij li thaum lub hwj chim mov tsis oscillate, qhov hluav taws xob tawm ntawm ob qho kawg ntawm lub loj lim capacitor (300V lim capacitor) yuav qeeb heev. Qhov hluav taws xob ntawm ob qho kawg ntawm lub lim capacitor yuav tsum raug tso tawm (ib qho hluav taws xob me me uas muaj lub zog siab tuaj yeem siv rau kev tawm), thiab tom qab ntawd nws tuaj yeem ntsuas tau, txwv tsis pub nws yuav tsis tsuas yog ua rau lub multimeter puas, tab sis kuj ua rau muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu. .
5. Lub sijhawm pib yuav tsum tau tswj xyuas thaum lub sijhawm tu
Thaum kho ntau yam tsis ua hauj lwm ntawm kev hloov hluav taws xob hloov hluav taws xob uas nws qhov hluav taws xob tso zis ntau dua li tus nqi ib txwm muaj, lub sijhawm pib yuav tsum yog luv li sai tau, thiaj li tsis ua kom tawg lub raj hloov thiab cov khoom thauj khoom, ua rau tsis tsim nyog. Tus qauv ntawm lub sijhawm pib yog lub sijhawm luv tshaj plaws uas yuav tsum tau ntsuas qhov voltage ntawm ib qho taw tes. Thaum lub sij hawm saib xyuas tiag tiag, koj tuaj yeem tuav cov hlau lead hauv ib txhais tes, nias lub khawm hloov nrog lwm tus tes, qhib lub hwj chim hloov, thiab tua lub hwj chim tam sim ntawd tom qab pom cov ntawv nyeem kom meej.
6. Tom qab hloov cov faulty Cheebtsam, saib xyuas cov zis voltage tus nqi ntawm lub switching fais fab mov thaum pib dua
Tshawb xyuas cov khoom siv hluav taws xob hloov thiab pom lossis xav tias muaj teeb meem nrog qee yam khoom. Tom qab hloov cov khoom siv no, saib xyuas qhov tso zis hluav taws xob ntawm lub zog hloov hluav taws xob (105-150V) thaum pib. Yog tias nws siab dua li tus nqi ib txwm, kaw sai sai. Tom qab ntawd xyuas raws li qhov ua txhaum ntawm cov zis hluav taws xob siab.
7. Kev tshuaj xyuas thiab kho cov fuse tube puas
Lub fuse ntawm lub fuse nyob rau hauv AC input Circuit Court yog tsis tshua muaj tshwm sim los ntawm lub ntuj puas tsuaj ntawm lub fuse, tab sis feem ntau ntawm nws yog tshwm sim los ntawm lub luv luv Circuit Court txhaum ntawm lub tom ntej Circuit Court, xws li luv luv Circuit Court ntawm lub mains rectifier diode thiab luv luv. Circuit Court ntawm lub hwj chim hloov raj. Yog li ntawd, yog tias koj ntsib ib qho txhaum uas lub fuse puas lawm, koj yuav tsum xub xyuas thiab hloov cov khoom tsis zoo saum toj no, thiab tom qab ntawd hloov lub fuse tshiab nrog lub tshuab kuaj. Thaum lub fuse puas lawm, nws yuav tsum tau hloov nrog cov khoom tshiab ntawm tib lub ntsiab lus es tsis txhob siv tooj liab, thiaj li tsis ua rau muaj kev puas tsuaj ntau dua rau lub voj voog. Thaum sab hauv ntawm lub raj xa hluav taws xob puas hloov xim dub lossis cov duab raj tawg, nws txhais tau hais tias qhov luv luv ntawm lub voj voog tom qab yog qhov hnyav, thiab nws yuav tsum tau xyuas kom zoo.
8. Overhaul ntawm Electrolytic Capacitor hauv Hloov Hloov Hloov
Qhov tsis ua hauj lwm ntawm electrolytic capacitors nyob rau hauv qhov kub kawg ntawm kev hloov pauv hloov pauv yog qhov siab, tab sis qee qhov capacitors zoo li qub thaum ntsuas nrog multimeter, tab sis qhov tseeb muaj teeb meem. Yog li ntawd, nws raug nquahu kom siv txoj kev hloov pauv los kho qhov 2.
