Terminal blocks yog ib qho tsim nyog tus cwj pwm hauv kev siv hluav taws xob. Vim lawv muaj ntau haiv neeg, nws muaj peev xwm hloov kho cov hluav taws xob circuits, kaw lub windings, vim lawv tsis siv, thiab disconnecting tsis tsim nyog circuits.
Terminal blocks yog ua los ntawm cov ntaub ntawv dielectric thiab ob peb lub ntsaws ruaj ruaj. Qee zaum, cov hlau me me lamellas tau siv (lawv tso cai rau koj los kho cov hlau yooj yim hauv qhov chaw nyuaj mus txog).
Terminals yog ib feem tseem ceeb ntawm cov khoom siv rau kev teeb tsa hluav taws xob thiab kev ua haujlwm. Ntawm ib sab ntawm lub davhlau ya nyob twg thaiv (raws li cov cai ntawm PUE), nws raug tso cai rau "cog" tsis pub ntau tshaj ob lub xov hlau ntawm tib txoj kab uas hla. Txwv tsis pub, kev sib cuag yuav tsis zoo, thiab cov xov hlau yooj yim yuav tsis crimp.
Terminal blocks feem ntau hu ua ntsia hlau clamp, tus pin clamp, davhlau ya nyob twg clamp, hlws ris thaiv lossis lub davhlau ya nyob twg thaiv. Tag nrho cov no yog cov npe ntawm tib tus cwj pwm, thiab lub npe tshwj xeeb yog tsim raws li qhov chaw ntawm lub davhlau ya nyob twg thaiv.
Cov khoom tso cai rau koj los txuas ib leeg-ntxhais xov hlau nrog cov khoom tso tseg. Hauv qhov no, ob lub xov hlau yuav tsum tau txuas los ntawm ntau sab.thawv, ntawm txawv screws. Raws li txoj cai, lub davhlau ya nyob twg thaiv yog carbolite, txawm li cas los xij, qhov no dielectric yog qhov tsis yooj yim, yog li carbolite tau hloov los ntawm cov khoom siv yas zoo dua. Cov khoom lag luam feem ntau yog siv rau kev teeb tsa cov khoom siv teeb pom kev zoo, cov khoom siv hauv tsev, rau kev sib txuas ntawm cov kab hluav taws xob tiv thaiv lub davhlau ya nyob twg.
Hnub no muaj ntau yam ntawm cov davhlau ya nyob twg:
- mounted;
- tsim rau kev teeb tsa hauv lub thawv sib txuas;
- designed rau Circuit Court breaker mounting.
Ntxiv rau, cov khoom siv davhlau ya nyob twg tuaj nrog cov ntsia hlau thiab lub caij nplooj ntoos hlav clamps. Cov khoom siv los tsim cov khoom kuj txawv. Cov ntaub qhwv yog ua los ntawm polyethylene thiab siv dav heev. Lawv qhov tshwj xeeb yog suav tias yog tus nqi qis thiab kev sib cais ntawm cov khoom nqa tam sim no nrog kev pab cuam ntawm lub cev (piv txwv li, nrog rab riam). Lub cev ntawm lub ncoo muaj ib lub qhov tshwj xeeb rau kev nruam mounting. Feem ntau, hauv cov ntaub qhwv polyethylene, tag nrho cov khoom nqa tam sim no yog ua los ntawm tooj dag, vim qhov no yog ib qho khoom siv zoo thiab pheej yig.
Qhov khoom lag luam no yog siv los txuas cov xov hlau hauv kev teeb tsa cov teeb pom kev zoo thiab kev teeb tsa ntawm cov thawv sib txuas. Tsis tas li ntawd, PE lub davhlau ya nyob twg thaiv yog siv tau rau hauv cov hlua ntawm lub qhov (socket) rau cov khoom siv hauv tsev.
Cov khoom siv niaj hnub niaj hnub feem ntau yog ua los ntawm polyamide. Cov khoom siv no yog siv rau hauv cov cuab yeej tshaj lij, xws li cov khoom siv tiv thaiv lub npe lossis cov thawv tseem ceeb. Cov khoom siv hluav taws xob siab.
Polyamide yog siv nyob rau hauv xws li circuits txhob txwm tshaj tawm, vim hais tias cov terminal blocks no kim heev, tab sis zoo. Lawv yog cov resistant rau sab nraud influences, raws li zoo raws li elastic thiab muaj hluav taws xob tsis kam. Dab tsi, hmoov tsis, polyethylene analogues tsis muaj.
Polyamide muaj qhov sib zog ua haujlwm siab, muaj kev tiv thaiv loj heev rau qhov tsis zoo ntawm qhov chaw tam sim no, qhov ntsuas qhov ntsuas qhov ntev ntev uas cov khoom siv tau. Tsis tas li ntawd, kev tua tus kheej yog tus yam ntxwv ntawm polyamide terminal blocks, vim tias cov khoom siv tsis yog nplaim taws, thiab tsis muaj halogen impurities nyob rau hauv muaj pes tsawg leeg.
Feem ntau, cov ntaub qhwv polyamide yog ua los ntawm tooj dag tam sim no-nqa cov nodes, uas tau them nrog cov yeeb yaj kiab galvanic.
