KEMA-KEUR yog lub cim kev nyab xeeb dav dav hauv kev lag luam hluav taws xob, hluav taws xob, thiab cov khoom lag luam.
ENEC yog daim ntawv pov thawj kev nyab xeeb uas tuaj yeem hloov pauv ntau lub tebchaws EU hauv European hluav taws xob, hluav taws xob, thiab cov khoom lag luam khoom lag luam.
CB yog ib daim ntawv pov thawj muab raws li IECEE (International Electrotechnical Commission) tus qauv.
Cov ntawv pov thawj ntawm IECEE cov tswvcuab hauv tebchaws tau kuaj xyuas kev nyab xeeb ntawm cov khoom siv hluav taws xob raws li IEC cov qauv, thiab lawv cov txiaj ntsig kev xeem, xws li CB cov ntaub ntawv xeem thiab CB daim ntawv pov thawj, tau lees paub los ntawm IECEE cov tswvcuab hauv tebchaws.
Lub hom phiaj ntawm kev xeem CB yog los txo cov nqi kuaj tsis tsim nyog los ntawm kev sim rov ua dua. Cov neeg siv khoom tsuas yog yuav tsum tau sim ib zaug kom tau txais daim ntawv pov thawj khoom los ntawm CB cov koom haum hauv lub tebchaws.
Dab tsi yog hom plugs thiab sockets tseem ceeb koom nrog?

Kev ceev faj rau European tsev neeg plugs
1. Rau cov khoom uas tsis yog hloov tau, lub hwj chim qaum ntev muaj cov hauv qab no:
—— Lub ntsaws tuaj nrog 0.5mm2 lub zog qaum, uas tuaj yeem ncav cuag qhov ntev tshaj plaws ntawm 2m
——16A ntsaws nrog 1.0mm2 fais fab qaum, siab tshaj plaws hlau ntev tuaj yeem ncav cuag 2m
2. Swinging fais fab qaum
(1) Ua tiav tawg ntawm qhov khoov (tej zaum nyob rau tib qhov chaw lossis tawg me ntsis), lossis nrog tus nqi tawg ntau tshaj qhov txwv: qhov no yog qhov tshwm sim tshwm sim, thiab cov ntsiab lus tawg feem ntau yog nyob ntawm qhov chaw tsis zoo ntawm cov qauv. Yog tias ib txhais tes tuav lub ntsaws thiab lwm qhov rub cov hlau, qhov chaw nrog lub vojvoog me me yog qhov feem ntau yuav tawg. Qhov chaw ntawm qhov chaw tawg yog me ntsis tawg, feem ntau yog vim muaj cov kab sib txuas ntawm qhov kawg ntawm lub network, lossis cov kab sib txuas uas sib tshuam thiab tsis zoo, yog li qhov kev tawg tsis tas yuav yog ib qho taw tes, tab sis ntau lub ntsiab lus. Tab sis feem ntau nws yog ze heev!
(2) Nws tawg ntawm qhov chaw riveting, uas tej zaum koj yuav tsis tau pom: qhov no yog vim riveting ntau dhau, ua rau kev puas tsuaj rau tus neeg xyuas pib. Txawm li cas los xij, thaum khoov, tus neeg xyuas pib nthuav dav thiab cog lus hauv cov rwb thaiv tsev, uas ua rau muaj qhov ua tiav lossis ib nrab tawg ntawm qhov taw tes riveting yam tsis tau tawg ntawm qhov khoov taw tes. Nws tuaj yeem pom meej los ntawm kev txiav. Kev saib xyuas yuav tsum tau them rau kev sib cais, thiab lub ntsaws yuav tsum tau ua kom sov thiab ua tib zoo saib xyuas. Qhov teeb meem no kuj muaj rau cov tuam txhab uas nws riveting zoo tsis tswj.
(3) Lub plhaub tau plam tawm, thiab cov tub ntxhais hlau tuaj yeem pom: qhov no feem ntau yog vim qhov kub thiab txias tsis txaus thaum lub sij hawm tsim cov ntsaws rau fuse PVC thiab hlau sheath, tshwj xeeb tshaj yog rau cov sheaths loj los yog roj hmab sheaths (uas tsis tuaj yeem. tau fused txhua), yog li lub zog sib txuas ntawm lub plhaub thiab lub ntsaws tsis txaus, ua rau kev hloov pauv thiab zawv zawg tawm thaum rov khoov dua.
(4) Rwb thaiv tsev rupture tuaj yeem nthuav tawm tus neeg xyuas pib: Muaj peb qhov laj thawj rau qhov xwm txheej no: ua ntej, cov rwb thaiv tsev ruptures nyob rau hauv rov khoov; Qhov thib ob yog vim li cas PVC ntawm tus Tsov tus tw ntawm lub ntsaws yog tawg, thiab lub qhov kua muag txuas ntxiv mus, tearing lub rwb thaiv tsev ib yam nkaus; Thirdly, tooj liab hlau tawg thiab punctures lub rwb thaiv tsev.
(5) Kev tawg ntawm cov hlua txuas: Cov khoom siv roj hmab tsis zoo lossis cov kab sib chaws tsis zoo tuaj yeem ua rau muaj kev cuam tshuam ntau dhau los yog kev ntxhov siab, ua rau tawg ntawm tus Tsov tus tw ntawm lub ntsaws!
(6) Tus neeg xyuas pib tho qhov rwb thaiv tsev thiab raug: qhov khoov ntawm tus neeg xyuas pib tawg, ua rau cov rwb thaiv tsev ua thinner hauv kev ntxhov siab. Cov hlau tooj liab ntawm qhov tawg ntawm qhov taw tes tuaj yeem tawm ntawm qhov rwb thaiv tsev, thiab txawm tias cov khoom sib txawv ntawm cov polarities tuaj yeem sib cuag, ua rau arc.
