Xov xwm

Raws li ib qho kev sib txuas sib txuas rau txhua tus engineers, lub davhlau ya nyob twg thaiv tau siv tau ntau xyoo los muab cov hlua ruaj ruaj ruaj ruaj rau ntau yam kev siv.Lub davhlau ya nyob twg thaiv, tseem hu ua lub davhlau ya nyob twg thaiv, lub davhlau ya nyob twg txuas, lossis lub davhlau ya nyob twg threaded, muaj cov vaj tse modular thiab cov insulator uas txuas ob lossis ntau cov xov hlau ua ke.Vim tias qhov kev sib txuas yog ib nrab mus tas li, lub davhlau ya nyob twg thaiv pab ua kom yooj yim rau kev soj ntsuam thiab kho cov txheej txheem.Txawm hais tias nws yog ib qho yooj yim tivthaiv, tab sis ua ntej kev xaiv ntawm lub davhlau ya nyob twg thaiv thiab nws cov specifications muaj kev nkag siab yooj yim lossis zoo.

Qhov kev sib tham no yuav hais txog cov hom thaiv dav hlau dav dav, cov khoom siv hluav taws xob tseem ceeb thiab kev xav txog kev siv tshuab, thiab muab qee cov ntsiab lus ntxiv los pab cov engineers xaiv.

Feem ntau configuration

PCB mount hom, laj kab thiab hom ncaj nraim yog peb hom dav hlau thaiv feem ntau hauv kev tsim.Cov lus hauv qab no teev peb hom sib txawv thiab lawv qhov laj thawj, kev teeb tsa, thiab kev teeb tsa.

Cov ntsiab lus tseem ceeb ntawm Hluav Taws Xob

Muaj ntau qhov tseem ceeb ntawm cov hluav taws xob tshwj xeeb uas yuav tsum tau xav txog thaum lub sij hawm tsim qauv, suav nrog cov hom phiaj thaiv dav hlau.Tshwj xeeb suav nrog:

Rated tam sim no.Feem ntau, cov lus qhia tshwj xeeb uas xav tau kev mloog zoo tshaj plaws hauv kev sib txuas lub thawv tsim yog qhov ntsuas tam sim no.Qhov no yog raws li peb yam: cov hluav taws xob conductivity ntawm cov terminals, qhov chaw hla ntu thiab qhov sib thooj kub nce.Thaum xaiv cov davhlau ya nyob twg thaiv, nws raug pom zoo tias qhov ntsuas tam sim no tsawg kawg yog 150% ntawm qhov siab tshaj plaws tam sim no ntawm lub kaw lus.Yog tias qhov ntsuas tam sim no ntawm lub davhlau ya nyob twg thaiv tsis raug thiab qhov kev khiav hauj lwm tam sim no siab dhau lawm, lub davhlau ya nyob twg thaiv yuav dhau los ua kom sov thiab puas tsuaj, ua rau muaj teeb meem kev nyab xeeb loj.
Rated voltage: Qhov ntsuas voltage ntawm lub davhlau ya nyob twg thaiv yog cuam tshuam los ntawm qhov sib nrug thiab lub zog dielectric ntawm nws lub tsev.Nyob rau tib txoj kev uas qhov ntsuas tam sim no raug xaiv, qhov ntsuas hluav taws xob ntawm lub davhlau ya nyob twg thaiv yuav tsum siab tshaj qhov siab tshaj plaws ntawm qhov system, suav nrog txhua qhov hluav taws xob surges uas yuav ua rau kev sib txuas.
Tus naj npawb ntawm tus ncej: Tus naj npawb ntawm tus ncej yog ib txoj hauv kev uas qhia txog tus naj npawb ntawm cov kab hluav taws xob ywj pheej uas muaj nyob rau hauv lub davhlau ya nyob twg thaiv.Qhov kev qhia tshwj xeeb no feem ntau txawv ntawm unipolar mus rau 24.
Qhov sib nrug: Qhov sib nrug yog txhais raws li qhov chaw nruab nrab ntawm cov ncej uas nyob ib sab, uas yog txiav txim siab los ntawm tag nrho cov kev ntsuam xyuas ntawm lub davhlau ya nyob twg thaiv thiab muaj feem cuam tshuam xws li creepage nrug, voltage / tam sim no, thiab clearance.Qee qhov piv txwv ntawm qhov sib txawv xws li 2.54mm, 3.81mm, 5.0mm, thiab lwm yam.
Hlau loj / Hom: Nyob rau hauv North America, hlau txais tau rau cov davhlau ya nyob twg thaiv yog nyob rau hauv American Wire gauge (AWG), uas qhia txog cov hlau loj los yog ntsuas tau rau lub module los xyuas kom meej tias cov hlau lub cev haum rau lub tsev.Hmoov zoo, feem ntau cov davhlau ya nyob twg thaiv muaj qhov ua rau muaj peev xwm ua tau raws li qhov ntau ntawm cov hlau loj xws li 18 txog 4 lossis 24 txog 12AWG.Ntxiv nrog rau lub ntsuas hluav taws xob, xav txog hom hlau nyob ntawm seb hom module xaiv.Twisted los yog multi-core xov hlau yog zoo tagnrho rau threaded terminals, thaum ib leeg-core xov hlau feem ntau yog khub nrog thawb-hauv davhlau ya nyob twg blocks.
Mechanical specifications tseem ceeb

Tom ntej no los ntawm cov neeg kho tshuab specification, uas hais txog qhov loj ntawm lub davhlau ya nyob twg thaiv, kev taw qhia, thiab yooj yim ntawm kev tuav ntawm kev sib txuas hauv kev tsim.Mechanical yam tseem ceeb muaj xws li:

Kev taw qhia kev xaim: Kab rov tav (90 °), ntsug (180 °) thiab 45 ° yog peb qhov kev qhia dav dav tshaj plaws.Qhov kev xaiv no nyob ntawm tus qauv tsim thiab cov kev taw qhia twg yog qhov haum tshaj plaws thiab yooj yim rau kev xaim.

Qib kev nyab xeeb thiab lwm yam kev xav

UL thiab IEC yog lub luag haujlwm tseem ceeb ntawm kev nyab xeeb rau kev lees paub lub davhlau ya nyob twg.UL thiab / lossis IEC cov qauv kev nyab xeeb feem ntau yog teev nyob rau hauv cov lus qhia tshwj xeeb ntawm lub davhlau ya nyob twg, thiab qhov ntsuas qhov ntsuas feem ntau sib txawv.Qhov no yog vim tias txhua lub tshuab siv cov qauv ntsuas sib txawv, yog li cov engineers yuav tsum nkag siab txog kev nyab xeeb ntawm lawv cov txheej txheem tag nrho los xaiv qhov tsim nyog cov davhlau ya nyob twg.

Txawm hais tias qee lub ntsiab lus yuav yog qhov kev xav hauv ntau qhov kev tsim, nws them rau xim kho lub tsev lossis cov nyees khawm ntawm lub davhlau ya nyob twg thaiv.Los ntawm kev xaiv cov xim tshwj xeeb rau lub davhlau ya nyob twg thaiv, cov engineers tuaj yeem yooj yim txuas cov ntsiab lus hauv cov txheej txheem nyuaj yam tsis muaj kev sib txuas tsis raug.

Thaum kawg, nyob rau hauv ib puag ncig lossis cov ntawv thov cuam tshuam nrog qhov kub thiab txias, lub davhlau ya nyob twg thaiv nrog cov qib kub siab dua tuaj yeem xaiv tau.
