Kev nyab xeeb ntawm txhua tus neeg nyob hauv yog nyob ntawm kev ua haujlwm zoo ntawm kev tso cov xaim hluav taws xob hauv lub tsev nyob. Txuas hluav taws xob xaim nrog kev pab ntawm twisting tau ntev dhau los tsis nco qab lawm. Niaj hnub no, tus kheej-clamping davhlau ya nyob twg blocks tau nce siv rau qhov no. Nws yog dab tsi thiab nws ua haujlwm li cas, koj tuaj yeem pom hauv peb qhov kev tshuaj xyuas luv luv.
Kev piav qhia
Terminal - ib lub cuab yeej tshwj xeeb uas muab kev sib txuas ntawm cov xaim hluav taws xob zoo. Txoj kev sib txuas ntawm ob qhov kawg ntawm cov xaim siv lub davhlau ya nyob twg yog tswj hwm los ntawm cov kev cai rau kev teeb tsa hluav taws xob thiab yog qhov kev ntseeg siab tshaj plaws thiab muaj kev nyab xeeb. Kev sib txuas cov cuab yeej, suav nrog tus kheej-clamping davhlau ya nyob twg blocks, yog siv los txuas ob qhov kawg ntawm cov hluav taws xob xaim nyob rau hauv lub mounting nodes ntawm hluav taws xob tes hauj lwm, raws li zoo raws li nyob rau hauv junction boxes. Lawv txawv hauv kev tsim, chaw tsim khoom, kev sib txuas mechanism.
Type of terminal blocks
Muaj ob hom kev lag luam niaj hnub nohluav taws xob terminals: ntsia hlau thiab self-clamping terminal blocks. Lub teb chaws Yelemees yog lub teb chaws loj tshaj plaws hauv lawv cov khoom. Lawv tiv thaiv cua sov ntawm qhov sib txuas ntawm ob lub xov hlau thiab, vim li ntawd, tsis ua haujlwm ntawm cov rwb thaiv tsev thiab luv luv ntawm cov xaim.
Cov ntsia hlau terminals yog cov khoom siv nrog lub plhaub yas, sab hauv uas muaj cov tshuaj ntsiav hlau nrog ob lub qhov. Qhov kawg ntawm cov hlau tsis muaj rwb thaiv tsev yog muab tso rau hauv cov qhov no. Kev sib txuas yog ua los ntawm cov ntsia hlau, uas yog clamped nrog ib tug yooj yim screwdriver. Screw terminals tuaj yeem siv tau ob qho tib si hauv cov hluav taws xob qis tam sim no thiab hauv cov hluav taws xob hluav taws xob.
Tus kheej-clamping terminal blocks yog ib qho khoom siv rau kev sib txuas ntawm ob qhov kawg ntawm cov xaim hluav taws xob, uas muaj lub tshuab tshwj xeeb uas muaj lub cev, lub zog thiab lub zog tswj. Kev sib txuas thiab kev sib txuas ntawm cov xaim yog nqa tawm siv lub zog tshwj xeeb uas tuaj yeem teeb tsa hauv ob txoj haujlwm. Self-clamping terminal blocks rau hluav taws xob xaim tuaj yeem muab pov tseg thiab rov siv dua. Cov khoom sib txuas ntawm hom no yog qhov yooj yim tshaj plaws rau kev siv, vim tsis tas yuav siv cov cuab yeej ntxiv los txuas ob kawg ntawm cov xaim hluav taws xob.
Qhov zoo ntawm tus kheej-clamping terminals
Tus kheej-clamping terminal blocks, txawm hais tias lawv yog txoj hauv kev yooj yim tshaj plaws los txuas qhov kawg ntawm cov hluav taws xob xaim, txawm li cas los xij lawv muaj lawv qhov zoo thiab qhov tsis zoo. Lawv cov txiaj ntsig suav nrog:
- yooj yim thiab nrawm ntawm kev teeb tsa;
- rov siv dua, txawm tiasCov khoom siv pov tseg tuaj yeem rov qab siv tau;
- muaj peev xwm ntawm kev sib txuas tooj liab thiab aluminium conductors.
Raws li rau lub davhlau ya nyob twg pov tseg, nws tsuas yog qhov txawv ntawm cov khoom siv rov siv tau yog qhov tsis muaj lub zog. Nyob rau hauv cov ntaub ntawv no, koj muaj peev xwm disconnect tus kawg ntawm cov hlau uas fasten lub hluav taws xob davhlau ya nyob twg thaiv ntawm tus kheej-clamping tsim siv ib tug zoo tib yam nyias tiaj tus ntsia hlau.
Flaws
Txhua lub thoob ntawm zib ntab muaj nws tus kheej ya hauv cov tshuaj pleev, thiab qhov no tsis muaj kev zam. Ntxiv rau tag nrho cov pom zoo, xws li ib tug connector muaj nws drawbacks:
- Nws tsis pom zoo kom siv nws tus kheej-clamping davhlau ya nyob twg blocks rau kev sib txuas ntawm txoj kab uas hla loj thiab cov xov hluav taws xob siab vim lawv lub peev xwm nias qis.
- cov khoom siv pov tseg tsis haum rau kev txuas cov xaim hloov tau yooj yim.
- thaum qhov kub thiab txias hloov pauv ntau, muaj peev xwm ua rau lub caij nplooj ntoo hlav tsis muaj zog, uas yuav ua rau cov neeg siv khoom sib txuas.
Txawm li cas los xij, lub ntsiab lus kawg tsuas yog kwv yees xwb. Thaum lub sijhawm xeem, cov lus no tsis tau lees paub.
Scope of application
Cov khoom siv no yog siv rau hauv txhua daim duab kab hluav taws xob uas muaj qhov siab tshaj qhov hluav taws xob mus txog 1000 V. Lawv muaj kev ntseeg siab sib npaug ntawm cov khoom siv hauv tsev thiab kev lag luam. Tab sis lawv yog cov neeg nyiam tshaj plaws thaum txhim kho hluav taws xob thaiv hauv lub neej txhua hnub vim tias tus nqi siab dua piv rau lwm tus.txoj kev sib txuas.
Kev xaiv ntawm cov khoom txuas yog ua raws li lub zog ntawm cov hluav taws xob hluav taws xob. Ntawm lub cev ntawm txhua tus kheej-clamping davhlau ya nyob twg thaiv, qhov siab tshaj plaws ntawm nws cov bandwidth yog qhia. Raws li txoj cai, cov terminals no tau nruab rau hauv cov thawv sib txuas lossis cov ntaub thaiv npog ntawm DIN rail.
Terminal xaiv
Rau tias qhov thaiv tus kheej-clamping davhlau ya nyob twg yog ib feem ntawm cov hlua hluav taws xob, nws txoj kev xaiv yuav tsum tau ua nrog lub luag haujlwm tshaj plaws. Cov xwm txheej yuav tsum xav txog thaum yuav ib lub connector:
- Qhov siab tshaj plaws ua tau tus neeg xyuas pib lub zog. Nws tuaj yeem pom nyob rau hauv daim ntawv hla tebchaws ntawm cov hluav taws xob cable lossis coj los ntawm txoj kab uas hla ntawm nws ntu.
- Qhov chaw txuas ntawm lub connector. Yog tias qhov chaw rau mounting lub davhlau ya nyob twg yog txwv, ces nws yog tsim nyog los xaiv ntau me me qauv ntawm tus kheej-clamping connector los yog nres ntawm lub ntsia hlau davhlau ya nyob twg.
- Producer. Thaum xaiv lub davhlau ya nyob twg, koj yuav tsum tsis txhob txuag thiab yuav pheej yig analogues ntawm dubious zoo, vim hais tias lawv yuav tsis muaj peev xwm tiv nrog lub hwj chim ntawm hluav taws xob Circuit Court, uas yuav ua rau overheating ntawm tus neeg xyuas pib thiab, raws li, ib tug luv luv Circuit Court..
Hluav taws xob txuas manufacturers
Hnub no, ntau lub tuam txhab loj thiab paub tau tau koom nrog hauv kev tsim cov khoom siv hluav taws xob. Cov npe nrov tshaj plaws tuaj yeem pom raws li lub rooj.

Cov khoom lag luam ntawm German tuam txhab Wago yog qhov tshwj xeeb ntawm kev ntseeg siab thiab kev nyab xeeb. Lub tuam txhab no sawv cev rau ntau yam khoom siv hluav taws xob thiab cov khoom siv ntxiv ntawm tus nqi pheej yig. Wago self-clamping terminal blocks muaj peb hom clamps: semi-caij nplooj ntoos hlav clamps, CAGE CLAMP clamps thiab FIT CLAMP clamps. Txhua tus ntawm lawv muaj cov cim tshwj xeeb ntawm lub cev ntawm lub connector, uas qhia cov naj npawb ntawm cov koob uas nws nyob. Thaum xaiv ib lub connector, nco ntsoov xav txog tag nrho cov yam ntxwv ntawm lub cuab yeej.
ABB yog ib lub ntiaj teb ua lag luam ntawm lub davhlau ya nyob twgcov khoom sib txuas. Ib qho ntawm nws cov neeg siv khoom loj tshaj plaws yog Gazprom, uas tsis ntseeg tau hais txog qhov zoo thiab kev ntseeg siab ntawm nws cov khoom. ABB tus kheej-clamping davhlau ya nyob twg thaiv muaj lub caij nplooj ntoos hlav siab ua rau hauv nws, tiv taus qhov kub thiab txias, nrog rau lub teeb thiab yooj yim ntawm kev teeb tsa.
Nruab qhov txuas txuas txuas
Thaum nws tus kheej sib sau ua ke tus kheej-clamping hluav taws xob davhlau ya nyob twg, tag nrho cov lus pom zoo yuav tsum ua raws li nruj me ntsis. Daim ntawv thov txuas txuas ib kauj ruam los ntawm phau ntawv qhia muaj cov kauj ruam hauv qab no:
- Tshem tawm qhov hluav taws xob ntawm hluav taws xob thiab xyuas kom nws tawm.
- Txhim kho qhov xav tau ntawm tus neeg xyuas pib. Thov nco ntsoov tias yuav tsum muaj tsawg kawg yog ntau yam clamps hauv lub davhlau ya nyob twg vim tias muaj cov kab sib txuas. Nws yog txwv tsis pub txuas ob peb lub hwj chim cables rau ib lub clamp ib zaug.
- Yog tias qhov kawg ntawm cov xaim tau twisted ua ntej kev teeb tsa, ces nws yuav tsum tau txiav tawm lawv cov khoom puas nrog cov hlau cutters.
- Tau qhov kawg ntawm cov hluav taws xob cable los ntawm cov pa roj carbon deposits thiab rwb thaiv tsev kom lawv haum dawb rau hauv lub qhov ntawm lub davhlau ya nyob twg thaiv.
- Muab qhov kawg ntawm tus neeg xyuas pib hauv qhov thaiv tus kheej-clamping thiab txuas.
- Ua kom qhov kev sib txuas ruaj ntseg thiab tuaj yeem tiv taus kev ntxhov siab.
