Dab tsi yog qhov ua rau lub taub hau hluav taws xob soldering hlau tsis ua haujlwm thiab cov kev daws teeb meem yog dab tsi?
Ntxiv rau qhov tsis ncaj ncees lawm kev twb kev txuas ntawm lub hwj chim qaum mus rau hauv av hlau davhlau ya nyob twg, qhov ua rau ntawm lub soldering hlau taub lub electrification tsis ua hauj lwm yog hais tias tom qab lub hwj chim qaum poob tawm ntawm lub soldering hlau core davhlau ya nyob twg, nws ntaus hauv av hlau ntsia hlau, ua rau cov hlau soldering. tswv yim los ua hluav taws xob. . Qhov kev ua tsis tiav no tuaj yeem ua rau hluav taws xob poob siab thiab ua rau cov khoom puas. Txhawm rau tiv thaiv txoj hlua hluav taws xob los ntawm kev poob, koj yuav tsum nco ntsoov xyuas seb cov ntsia hlau crimping ntawm cov hlau tuav yog xoob lossis ploj lawm. Yog tias nws xoob lossis ploj lawm, nws yuav tsum tau hloov raws sijhawm.
Induced voltage tshwm sim thaum AC tam sim no txuas, tab sis tsis muaj av zoo. Yog tias nws tsis yog hauv av, tsuas yog siv lub tshuab hluav taws xob uas tsis muaj hluav taws xob nrog cov tub ntxhais hlau transformer. Yog tias lub LED raug hlawv, tej zaum yuav muaj qhov xau lossis qhov hluav taws xob induced siab dhau.
Cov av xaim ntawm cov hlau taub hau yog txuas nrog hauv av xaim los ntawm cov ntsia hlau hauv av txias. Yog tias qhov av xaim no yog grounded nyias yam tsis tau hla hauv av txias, thiab yog tias qhov chaw nres tsheb soldering muaj ob lub ntsaws, qhov kawg hauv av ntawm qhov chaw nres tsheb yuav tsum muaj kev nyab xeeb. Yog tias nws yog daim duab peb sab ntsaws, nco ntsoov txuas cov av xaim ntawm daim duab peb sab ntsaws rau hauv av. Siv cov hlau soldering rau soldering LED teeb hlaws. Nws yuav tsum yog 220V hluav taws xob soldering hlau thiab tsis grounded. Lub induced voltage ntawm lub soldering hlau taub yog siab heev, thiab cov LED voltage feem ntau yog nyob nruab nrab ntawm 1.5-3.5, uas yuav yooj yim zom cov LED nti.
Qhov hluav taws xob ntawm lub taub hau soldering yog ib qho hluav taws xob ntau zaus induced voltage. Nws muaj ib tug capacitance ntawm lub soldering hlau taub thiab lub kauj, uas yog induced hluav taws xob. Nws yog qhov zoo tshaj rau av. Qee lub sij hawm nws tuaj yeem rhuav tshem lub teeb-emitting diodes thiab cov raj xa dej.
Txawm hais tias nws yog inductive, nws tuaj yeem ua kev puas tsuaj rau LEDs (lub teeb xiav yog qhov feem ntau yuav raug puas), thiab qee qhov ICs rhiab tuaj yeem raug puas tsuaj inexplicably. Yog tias tsis muaj cov xaim hauv av, koj tuaj yeem nrhiav tau ib txoj hauv kev los ua kom lub peev xwm ntawm tib neeg lub cev thiab cov hlua hlau taub hau tib yam, uas tuaj yeem zam kev puas tsuaj rau cov khoom. Weld ib tug hlau mus rau lub thoob hlau uas txuas nrog rau cov hlau ib feem ntawm lub soldering hlau taub, thiab ces welded ib lub nplhaib hlau. Hook lub nplhaib hlau ntawm koj tus ntiv tes thaum vuam.
Nws yuav tsum tau muab sau tseg hais tias lub soldering hlau taub thiab lub tes tsho hlau yuav tsum nyob rau hauv kev sib cuag zoo. Yog hais tias lub taub hau hlau tau kub hnyiab tau ntev, nws zoo li yuav tsis muaj teeb meem hauv kev sib cuag nrog lub tes tsho hlau. Qhov tseeb, yog hais tias lub taub hau hlau yog hluav taws xob raug tshem tawm, tseem yuav muaj qhov cuam tshuam tam sim no. , lub ntsiab lus no tseem ceeb heev.
