Puas yog 48V DC soldering hlau txuas diodes hauv series?
Diodes tsis tuaj yeem txuas rau hauv series, ib qho me me resistor yuav tsum tau txuas nrog hauv series los faib cov voltage. Diodes yog siv rau rectifiers thiab tsis muaj kev cuam tshuam ntau rau kev faib hluav taws xob. Resistors yog cov khoom siv hluav taws xob tshwj xeeb siv rau kev faib hluav taws xob. Ua ntej, siv ib lub multimeter los ntsuas qhov tsis kam ntawm cov hluav taws xob soldering hlau. Raws li tus nqi tiv thaiv no, txuas qhov sib npaug ntawm qhov sib npaug hauv cov koob, tom qab ntawd qhov hluav taws xob faib rau hluav taws xob soldering hlau yuav raug txo mus rau 1/2 ntawm tus nqi qub. Yog hais tias qhov kub ntawm cov hluav taws xob soldering hlau yog tsawg dhau, nws tsis txaus, koj tuaj yeem tshem tawm qhov resistor thiab rov txuas lub resistor nrog tus nqi tsis kam ntawm 1/2 ntawm qhov resistor hauv series, kom cov hluav taws xob faib rau hluav taws xob soldering hlau. yog 2/3 ntawm qhov qub. Los ntawm kev sim rov ua dua, koj tuaj yeem pom koj qhov zoo tshaj plaws cov nqi tiv thaiv.
Qhov hluav taws xob ntawm DC 48 volt hluav taws xob cov khoom siv hluav taws xob yuav raug txo los ntawm kwv yees li 0.7 volts, thiab kev sib txuas rov qab yuav raug txiav tawm ntawm lub hwj chim. Nco ntsoov tias qhov voltage ntawm lub diodes nyob rau hauv series yuav tsum zoo dua yog> 65 volts, thiab rau pem hauv ntej tam sim no> ob zaug qhov kev khiav hauj lwm tam sim no.
Puas yog hluav taws xob soldering hlau series diodes ua tiav lub hom phiaj ntawm kev ua kom txias?
DC fais fab mov ncaj qha muab lub zog rau cov hlau soldering. Txij li thaum tsis muaj qhov ntsuas kub thiab ntsuas hluav taws xob, qhov ntsuas kub tsis tuaj yeem khaws cia tas li thiab yuav txawv nrog thaj chaw soldering. Yog tias qhov kub qis dhau lawm, qhov ceev ntawm tin melting yuav qeeb, thiab yog tias qhov kub thiab txias siab dhau lawm, lub hau ntawm cov hlau soldering yuav oxidized sai heev, ua rau tsis muaj tinning. Txhawm rau daws cov teeb meem ntawm qhov kub tsis tu ncua, txoj kev zoo tshaj plaws yog txhawm rau txhawm rau ntsuas qhov kub thiab txias thiab tswj hwm Circuit Court. Yog tias cov hluav taws xob siv hluav taws xob zoo tib yam siv tau raug hloov kho, txij li cov hlau soldering nws tus kheej tsis muaj qhov ntsuas kub, nws tsis tuaj yeem hloov mus rau qhov kub thiab txias, thiab qhov kub tsuas tuaj yeem txo qis los ntawm kev txo qhov voltage.
Ordinary diodes, nyob ntawm tus qauv, lub zog rau pem hauv ntej poob ntawm qhov qub rectifier diodes feem ntau nyob ib ncig ntawm {{{0}}.7V, thiab lub zog pem hauv ntej poob ntawm Schottky diodes tseem qis dua. Yog hais tias cov hlau soldering yog powered los ntawm lub hwj chim zaus alternating tam sim no, lub diode nyob rau hauv series muaj peev xwm ua si lub luag hauj lwm nyob rau hauv txo voltage, vim hais tias tus nqi ntawm cov voltage yuav tsum tau halved tom qab lub alternating tam sim no rectified los ntawm ib nrab-yoj ntawm lub diode. Tab sis rau DC voltage, qhov zoo tshaj plaws voltage poob ntawm lub diode tsuas yog 0.7V ntawm feem ntau, thiab qhov ntau ntawm qhov voltage poob yog me me, uas tsis muaj qhov pom tseeb ntawm qhov kub poob.
Yog tias koj xav txo qhov kub thiab txias, koj tsuas tuaj yeem txo qhov voltage ntau. Muaj ob txoj hauv kev los txo qhov voltage. Ib qho yog los hloov qhov siv hluav taws xob ntawm qhov ntsuas hluav taws xob ib feem ntawm cov zis sab hauv ntawm lub charger. Txoj kev hloov no yuav tsum muaj qee yam kev paub hauv Circuit Court thiab lub hauv paus. Lwm txoj hauv kev yog siv lub tiav DC adjustable kauj ruam-down module los hloov qhov tso zis voltage los ntawm qhov sib txawv resistor. Thiab nws tuaj yeem hloov kho kom txias txias, thiab cov khoom tshawb pom tuaj yeem muab ntxiv rau hauv cov hlau soldering, thiab qhov hluav taws xob yuav raug txo qis tom qab cov hlau soldering tau muab tso rau hauv.
