Vim lub peculiarities ntawm tag nrho-xim LED zaub qhov chaw teeb tsa, xws li kev teeb tsa tsis raug, kab kev puas tsuaj, kev puas tsuaj rau cov khoom siv hluav taws xob hauv lub thawv hloov, qee cov khoom siv hluav taws xob tsis dhau los ntawm lub thawv hloov, thiab lwm yam, thiab kev ua haujlwm tsis raug ntawm Lub leakage protector nws tus kheej Thiab tsis kam ua haujlwm, ua ke nrog qhov tsis ua haujlwm ntawm kev teeb tsa lub leakage protector raws li kev siv hluav taws xob tiag tiag, ua rau tsis tu ncua ntawm tag nrho cov leakage protector.
1. Qhov kev teeb tsa ntawm cov khoom tiv thaiv tawm yog tsis tsim nyog
Vim lub peculiarities ntawm tag nrho-xim LED zaub qhov chaw teeb tsa, xws li kev teeb tsa tsis raug, kab kev puas tsuaj, kev puas tsuaj rau cov khoom siv hluav taws xob hauv lub thawv hloov, qee cov khoom siv hluav taws xob tsis dhau los ntawm lub thawv hloov, thiab lwm yam, thiab kev ua haujlwm tsis raug ntawm Lub leakage protector nws tus kheej Thiab tsis kam ua haujlwm, ua ke nrog qhov tsis ua haujlwm ntawm kev teeb tsa lub leakage protector raws li kev siv hluav taws xob tiag tiag, ua rau tsis tu ncua ntawm tag nrho cov leakage protector.
Ntxiv nrog rau kev txhim kho kev tswj hwm rau qhov xwm txheej no, nws kuj tseem yuav tsum tau ua kom muaj kev sib haum xeeb ntawm kev tiv thaiv kev xau raws li qhov xwm txheej tiag tiag los ntawm kev pom zoo. Cov khoom tiv thaiv to ntawm cov khoom siv hluav taws xob tseem ceeb ntawm cov kab nkag tuaj yeem siv los ua kev tiv thaiv tag nrho los tiv thaiv hluav taws xob hluav taws xob thiab hluav taws xob luv luv. Nws kuj ua hauj lwm raws li kev tiv thaiv thaub qab rau txhua qhov kev tiv thaiv me me. Nws qhov ntsuas hluav taws xob tuaj yeem nyob nruab nrab ntawm 2{{2}0 thiab 500 mA. Xaiv qhov nruab nrab, lub sij hawm xau tawm tuaj yeem yog 0.2 ~ 0.3s. Nyob rau hauv txoj kev no, kev cuam tshuam ntawm surge voltage, surge tam sim no, thiab electromagnetic cuam tshuam ntawm tag nrho cov leakage protector tuaj yeem txo qis, thiab kev xaiv thiab kev ntseeg siab ntawm kev ua haujlwm ntawm tag nrho cov leakage protector tuaj yeem txhim kho. Yog hais tias qhov kev tiv thaiv cov dej xau thib ob hauv txhua qhov kev tiv thaiv cov dej xau tuaj yeem ua rau muaj kev tiv thaiv zoo, qhov zaus ntawm kev txav mus los ntawm tag nrho cov leakage protector ntawm qhov chaw tsim kho tuaj yeem txo qis heev.
2, tsis muaj kev tiv thaiv theem nrab lossis qib thib peb hauv kev tiv thaiv ntau yam
Qhov kawg-theem leakage protector nyob rau hauv lub thawv hloov yog lub ntsiab tiv thaiv ntawm cov khoom siv hluav taws xob. Yog tias qhov kawg-theem leakage tiv thaiv tsis tau teeb tsa, puas lossis raug xaiv tsis raug, nws yuav ua rau cov khoom tiv thaiv sab saud mus rau ntau zaus. Txij li thaum muaj ntau cov hlau conductors nyob rau hauv tag nrho-xim LED zaub, thiab muaj ntau cov hlau txuas, yog hais tias cov hlau rwb thaiv tsev tsis zoo heev, nws yuav ua rau tsis tu ncua; qee lub qhov (sockets) kuj tau ntxiv, thiab nyob rau hauv ntau rooj plaub, cov khoom tiv thaiv tsis tau ntsia. Ua rau cov dej xau. Tsuas yog thaum muaj kev tiv thaiv kev tiv thaiv theem nrab lossis qib thib ob yog tsim nyob rau hauv txhua qhov kev tiv thaiv, tuaj yeem txo qis ntawm cov khoom tiv thaiv kom zoo.
3, tus tiv thaiv leakage nws tus kheej muaj qee yam kev txwv
(1) Cov khoom tiv thaiv tam sim no, txawm tias electromagnetic los yog hluav taws xob, siv cov hlau nplaum induction voltage transformers los khaws cov xau tam sim no hauv lub ntsiab ntawm cov khoom siv hluav taws xob. Nws yog tsis yooj yim sua kom npaj peb-theem lossis peb-theem plaub-xaim hauv lub nplhaib sib nqus kom sib npaug. Peb-theem fais fab load ntawm tag nrho-xim LED zaub tsis tuaj yeem sib npaug tag nrho. Nyob rau hauv siab tam sim no los yog siab overvoltage, ib tug tej yam electromotive quab yuam yuav induced nyob rau hauv lub magnetic nplhaib nrog siab permeability, uas yog loj heev rau ib tug tej yam kev mob, nws yuav ua rau kom lub leakage protector mus txawv tebchaws. Txij li thaum lub leakage protector nrog ib tug loj rated tam sim no siv ib tug kuj loj sib nqus nplhaib, lub leakage flux generated kuj loj, thiab cov to tam sim no yuav tsum tau kov yeej lub magnetizing quab yuam ntawm lub nplhaib sib nqus nws tus kheej, uas ua rau ib tug loj rated tam sim no ntawm lub leakage protector. kev siv tiag tiag, qhov qis dua qhov rhiab heev, qhov ntau dua qhov tsis lees paub.
(2) Muaj qhov tsis paub meej ntawm qhov ntsuas qhov ntws tawm tam sim no thiab qhov ntsuas tsis ua haujlwm tam sim no ntawm tus tiv thaiv to. Thaum cov dej xau tam sim no ntawm tus tiv thaiv cov dej xau hloov pauv hauv cheeb tsam no, nws yuav ua rau cov dej xau tiv thaiv mus rau qhov tsis sib xws.
4, kev xaiv ntawm cov khoom tiv thaiv tawm yog tsis tsim nyog
(1) Cov ntsuas hluav taws xob tam sim no siv nyob rau hauv lub thawv hloov siab tshaj 30mA, lossis ntau dua ob npaug ntawm cov khoom siv hluav taws xob tam sim no, lossis cov khoom siv hluav taws xob xau nrog lub sijhawm ncua raug xaiv, vim qhov ntsuas cov pa tawm tam sim no nce lossis txo qis. kev tiv thaiv rhiab heev, thaum muaj qhov txhaum cai tshwm sim, qhov kawg-theem leakage protector tsis ua, thiab cov khoom tiv thaiv saum toj kawg nkaus tuaj yeem ua.
(2) Qhov pib tam sim no thaum lub zog tag nrho-xim LED zaub feem ntau kuj loj, thiab qhov tam sim no loj tuaj yeem ua rau cov khoom tiv thaiv. Yog li ntawd, cov txee ntawm cov zaub yuav tsum tau hluav taws xob hauv cov khoom siv ntau li ntau tau. Tsis tas li ntawd, nyob rau hauv dav dav, ib tug electromagnetic to tiv thaiv uas tsis rhiab heev rau surge overvoltage thiab overcurrent yuav tsum tau xaiv; los yog ib qho hluav taws xob tiv thaiv hluav taws xob uas yog 1.5 mus rau 2 lub sij hawm loj dua qhov ntsuas tam sim no, tab sis raws li qhov kawg kev tiv thaiv to, ntsuas qhov hluav taws xob tam sim no yuav tsum tsis txhob siab dua 30mA.
Nyob rau hauv luv luv, qhov nquag tripping ntawm lub leakage protector yog tshwm sim los ntawm ntau yam. Qhov tseem ceeb tshaj plaws yog los npaj cov dej xau tiv thaiv kom tsim nyog, txo qhov kev tiv thaiv ntawm qib thib ob lossis qib thib peb los tiv thaiv kev tiv thaiv, thiab xaiv cov khoom tiv thaiv kom raug thiab cov xaim hluav taws xob kom ua rau txhua tus thib ob lossis qib thib peb cov dej xau tiv thaiv nyob rau hauv qhov muaj nyob hauv. muaj txiaj ntsig tiv thaiv xeev; ntawm qhov tod tes, nws yog txhawm rau txhim kho kev tswj xyuas hluav taws xob thiab txhim kho cov neeg siv hluav taws xob zoo los ntawm kev cob qhia, thiab tshem tawm cov tsis siv hluav taws xob, kom muaj kev ruaj ntseg ntawm hluav taws xob tuaj yeem txhim kho, Nws kuj tuaj yeem txo qhov tsis tshua muaj kev cuam tshuam ntawm cov hluav taws xob tiv thaiv, thiab tsim cov khoom siv hluav taws xob zoo dua rau kev ua haujlwm ib txwm muaj ntawm cov xim puv LED.
