Qhov cuam tshuam ntawm Terminal Blocks Ntawm Ib puag ncig kev lag luam thiab lawv daim ntawv thov xaiv

Cov yam tseem ceeb hauv kev xaiv cov khoom siv hluav taws xob zoo - cov nqi qis hauv cov davhlau ya nyob twg yog raws li hauv qab no:
1. Qhov chaw khaws cia ntawm cov davhlau ya nyob twg sib txawv los ntawm kev tswj xyuas huv, cua sov lossis cua txias, cov chaw cia khoom, chaw ua haujlwm lossis chaw ua haujlwm rau qhov chaw tsis sib haum xeeb.
Kev pabcuam lub neej ntawm cov terminals yuav raug cuam tshuam los ntawm tshav kub, av noo lossis corrosion.
2. Kev thauj mus los ib puag ncig cuam tshuam nrog cov teeb meem tshwm sim los ntawm kev vibration thiab kev sib tsoo tsim thaum lub sijhawm ua haujlwm ntawm cov tsheb thauj mus los thiab lwm yam khoom siv kho tshuab, txoj kev chaw, thiab cov cuab yeej thauj khoom thiab thauj khoom.
Cov huab cua kub heev feem ntau ua ke thiab ua rau muaj kev cuam tshuam ntawm kev co thiab kev sib tsoo.
3. Kev ntseeg siab yog qhov tseem ceeb heev hauv kev txiav txim siab ua lag luam.
Los ntawm qhov kev xav ntawm tus kws ua haujlwm zoo lossis tus kws tshaj lij kev ntseeg siab, kev ntseeg siab yuav tsum tau txhais tias "kev ua haujlwm tsis tu ncua lossis qhov ua tau zoo tshaj plaws ntawm kev ua haujlwm tsis ua haujlwm nyob rau hauv cov xwm txheej," lossis "qhov ntau tshaj qhov tshwm sim uas qee yam tuaj yeem ua haujlwm ib txwm nyob rau hauv cov xwm txheej thiab hauv ib qho tshwj xeeb. lub sijhawm."
Lub zog tuav cov yam tseem ceeb ntawm cov khoom tseem ceeb hauv kev xaiv cov khoom siv hluav taws xob zoo - cov nqi qis hauv cov davhlau ya nyob twg:
Ib qho tseem ceeb ntawm kev xaiv cov khoom siv hluav taws xob zoo tshaj plaws - cov nqi qis hauv cov davhlau ya nyob twg uas yuav tsum tau xav txog ua ntej yog lub zog tuav lub peev xwm ntawm cov cuab yeej. Tsuas yog nyeem ntawv cov ntaub ntawv tsis tau lees paub cov ntaub ntawv sib piv. Cov kws tsim khoom yuav tsum nkag siab tias cov khoom lag luam cov ntaub ntawv ua tau zoo li cas hauv phau ntawv no tau sim thiab txiav txim siab li cas.
Tam sim no, tsis muaj kev sib koom ua ke rau kev txiav txim siab lub zog thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob zoo-cov nqi qis ntawm cov khoom siv hluav taws xob los ntawm cov koom haum xws li UL, IEC, CSA thiab DIN. Cov neeg siv yuav tsum nkag siab qhov txawv ntawm UL thiab IEC specifications. Cov lus qhia tshwj xeeb ntawm cov khoom siv hluav taws xob zoo-cov nqi qis hauv cov khoom siv hauv Tebchaws Europe siv cov qauv IEC, thaum cov khoom tsim hauv Tebchaws Meskas siv cov qauv UL.
Qhov sib txawv ntawm ob tus qauv yog qhov loj heev. Cov kws tsim khoom uas tsis nkag siab txog cov txheej txheem ntawm kev txiav txim siab cov khoom tshwj xeeb yuav muaj kev pheej hmoo loj vim tias cov khoom siv xaiv yuav tsis ncav cuag lub zog uas yuav tsum tau muaj, lossis cov kev qhia tshwj xeeb ntawm cov khoom xaiv tau dhau los ntawm cov qauv tsim. Hauv Tebchaws Europe, qhov ntsuas tam sim no ntawm cov cuab yeej yog txiav txim siab los ntawm kev saib xyuas qhov kub thiab txias ntawm tus neeg xyuas pib hlau thaum qhov tam sim no nce. Thaum qhov kub ntawm tus pin hlau yog 45 degree siab tshaj qhov ntsuas kub, cov neeg ua haujlwm ntsuas yuav siv lub sijhawm tam sim no raws li tus nqi tam sim no (lossis tus nqi siab tshaj plaws tam sim no) ntawm lub cuab yeej. Lwm yam khoom hauv IEC specification yog qhov tso cai tam sim no tus nqi, uas yog 80% ntawm qhov siab tshaj plaws tam sim no. Nyob rau hauv sib piv, tus qauv UL siv 90% ntawm tus nqi tam sim no thaum cov hlau conductor kub yog 30 degree siab tshaj qhov kub ntawm ambient raws li cov cuab yeej nominal nqi tam sim no. Nws tuaj yeem pom tau tias qhov kub ntawm cov khoom siv hlau yog qhov tseem ceeb heev hauv txhua daim ntawv thov. Qhov no tseem ceeb dua rau cov khoom siv hauv kev lag luam. Vim tias cov cuab yeej siv feem ntau yuav tsum tau ua haujlwm hauv ib puag ncig nrog qhov kub txog li 80 degree. Yog tias qhov ntsuas kub ntawm lub davhlau ya nyob twg yog 30 degree lossis 45 degree siab dua qhov ntsuas kub no, qhov ntsuas kub ntawm lub davhlau ya nyob twg yuav siab tshaj 100 degree. Nyob ntawm seb tus nqi nominal thiab cov khoom siv rwb thaiv tsev siv los ntawm cov khoom siv xaiv, cov khoom yuav tsum ua haujlwm ntawm qhov tam sim no qis dua tus nqi ntsuas los xyuas kom meej tias lawv tuaj yeem ua haujlwm tau zoo nyob rau hauv qhov kev xav tau kub. Qee lub sij hawm, cov khoom tsim nyog rau cov khoom ntim ntim yuav tsis ua tau raws li qhov xav tau ntawm cov cua sov kom zoo, yog li tam sim no ntawm cov khoom siv hluav taws xob zoo li no-cov nqi qis hauv cov khoom siv hluav taws xob yuav tsum qis dua cov nqi ntsuas thaum siv. Qhov no qhia txog qhov tseem ceeb ntawm kev xaiv cov terminal blocks li cas.
Raws li cov tuam txhab mus thoob ntiaj teb thiab xav tau tsim cov tshuab uas tuaj yeem muag tau thoob ntiaj teb, cov neeg tsim qauv siv zog siv hluav taws xob zoo tshaj plaws hauv cov khoom siv hluav taws xob-cov nqi qis hauv cov khoom lag luam uas tsim tawm hauv lwm lub tebchaws. Vim tias Tebchaws Europe siv txoj kev ntsuas tus nqi nominal, nws yog ib qho kev coj ua hauv Tebchaws Europe siv cov khoom siv qis dua tus nqi nominal hauv kev tsim. Txawm li cas los xij, ntau tus neeg tsim qauv Asmeskas tsis paub txog lub tswv yim no, thiab yog tias lawv tsis nkag siab qhov sib txawv ntawm cov qauv, lawv yuav nyuaj rau cov txheej txheem tsim.
Lwm qhov tseem ceeb uas feem ntau tsis saib xyuas thaum xaiv cov khoom siv yog qhov kev siv thev naus laus zis siv hauv cov khoom. Feem ntau cov khoom siv hluav taws xob zoo - cov khoom siv hluav taws xob qis qis tseem siv los ntawm qhov sib txuas. Txoj kev no muab kev txhawb nqa txhua yam uas yuav tsum tau ua thiab ua kom cov khoom siv hluav taws xob sib cuag nrog lub hwj chim txheej embedded nyob rau hauv multi-layer circuit board. Muaj ntau ntau hom pins siv los txuas cov terminals rau lub rooj tsav xwm Circuit Court. Qee lub tuam txhab tsuas yog muab cov qauv ib tus pin, thaum lwm tus muab cov khoom siv ntau tus pin. Qhov kom zoo dua ntawm cov khoom siv ntau tus pin yog tias nws tuaj yeem faib cov khoom tam sim no sib npaug rau cov kab hluav taws xob hauv Circuit Court, muab kev ruaj ntseg zoo dua qub thiab txhim kho qhov ruaj khov ntawm vuam.
Cov tsos mob ntawm qhov tseem ceeb hauv kev xaiv cov terminals zoo - cov nqi qis:
Qhov thib ob tseem ceeb tshaj plaws uas yuav tsum tau xav txog hauv kev xaiv cov terminals zoo - cov nqi qis qis yog cov tsos. Txawm hais tias lub npe "lub zog zoo terminals - luv nqi terminals" tsis zoo nkauj, ntau lub tuam txhab ntseeg tias nws ua lub luag haujlwm tseem ceeb hauv cov khoom muag thiab cov neeg siv khoom zoo. Lub hwj chim terminals yuav tsum yooj yim rau nruab rau ntawm qhov chaw vim tias lawv feem ntau ntsia rau pem hauv ntej ntawm cov khoom vaj huam sib luag uas yooj yim pom. Nyob rau hauv txoj kev no, cov neeg lag luam feem ntau xav kom muaj qee yam hais hauv qhov pom ntawm cov khoom siv hluav taws xob. Tab sis feem ntau nws tshwm sim tias cov engineers tsim cov khoom lag luam uas ua tau raws li txhua qhov kev xav tau ntawm txhua yam khoom siv thiab hluav taws xob, tab sis yuav tsum tau hloov pauv vim lawv tsis ua raws li cov kev xav tau ntawm kev muag khoom. Yog tias qhov no tshwm sim thaum kawg ntawm lub voj voog tsim (feem ntau thaum lub tuam txhab lag luam thawj zaug pom tus qauv), kev sib cav sib cav sib ceg tsis muaj kev zam thiab yuav ua rau tus nqi siab dua thiab xa khoom qeeb. Hauv ntau lub tshuab tswj kev lag luam, cov khoom siv davhlau ya nyob twg feem ntau yog ib qho ntawm ob peb qhov chaw uas cov kws tshaj lij yuav tsum tau them nyiaj tshwj xeeb rau. Txawm hais tias lawv cov neeg siv interface yog qhov yooj yim (tsuas yog cov ntsia hlau), lawv tseem ceeb heev rau kev ua haujlwm ntawm cov khoom siv.
Feem ntau, raws li qhov tam sim no nce, cov xov hlau ua thicker, thiab lub zog yuav tsum tau nruj cov xov hlau tuab ntawm cov khoom siv hluav taws xob zoo-cov nqi qis hauv cov davhlau ya nyob twg kuj yuav tsum tau nce ntxiv. Yog li ntawd, qhov zoo tshaj plaws davhlau ya nyob twg blocks-qis nqi davhlau ya nyob twg blocks yuav tsum tau loj screws thiab muaj zog rwb thaiv tsev vaj tse. Qee zaum me me screws yog siv los txuag chaw. Qhov no feem ntau yog cov ntaub ntawv hauv cov khoom lag luam compact heev. Qee cov xov hlau muaj txoj kab uas hla ntau dua 1/4 nti, yog li cov ntsia hlau me me no nyuaj rau kev cuam tshuam nrog rau qhov tseem ceeb ntawm kev xaiv davhlau ya nyob twg.
Kev nyab xeeb yog ib yam uas txhua qhov kev lag luam yuav tsum tau saib xyuas. Tsuas yog los ntawm kev ua kom muaj kev nyab xeeb tuaj yeem ua tiav kev ua haujlwm siab. Ib yam li kev ua haujlwm ntawm lub tshuab tom yuav tsum tau ua tib zoo saib xyuas kom muaj kev nyab xeeb, lub tshuab tom yog cov cuab yeej siv tsis tau zoo rau ntau cov ntawv hlau ua, huab cua duct, thiab lwm yam. Yog li, dab tsi ua kom muaj kev nyab xeeb ntawm lub tshuab tom?
1. Cov cuab yeej tiv thaiv: siv los cais tus neeg teb xov tooj los ntawm cov khoom sib hloov, cov khoom nyob thiab cov khoom tsis zoo uas tsim los thaum ua cov khoom siv tshuab. Xws li siv tus number case, iav npog, hluav taws xob number case, hlau nti baffle, tiv thaiv railing, thiab lwm yam.
2. Cov khoom siv kev nyab xeeb. Siv los txhim kho kev ntseeg siab ua haujlwm ntawm cov cuab yeej siv tshuab thiab khoom siv.
