Dab tsi yog mounting hlau?
Txheem
Lub mounting hlau yog ib qho insulated tus neeg xyuas pib haum rau qhov tsis tshua muaj hluav taws xob thiab tsis tshua muaj kev siv tam sim no. Cov xaim sib txuas ua tau zoo nyob rau hauv qhov chaw kaw thiab muaj nyob rau hauv ntau yam kev teeb tsa nrog ntau yam conductors, rwb thaiv tsev thiab cov ntaub ntawv sheath.
Hauv phau ntawv qhia no, peb yuav kawm ntxiv txog kev sib txuas ntawm cov xaim thiab seb yuav nrhiav dab tsi hauv kev sib txuas ruaj ntseg:
Dab tsi yog qhov txuas hlau siv rau?
Cov xaim txuas feem ntau yog siv rau hauv kev tswj vaj huam sib luag, tsheb, ntsuas, qhov cub thiab khoos phis tawj, khoom siv hluav taws xob, tsheb lag luam thiab cov khoom siv hluav taws xob sab hauv.
Cov hlau txhuas feem ntau yog siv rau hauv cov khoom siv hluav taws xob kaw, txawm hais tias qee yam kuj tseem siv tau rau cov tub rog nyuaj.
Feem ntau cov xov hlau txuas tau ntsuas rau 600V; Txawm li cas los xij, qhov ntsuas kub sib txawv los ntawm kev tsim.
Xaiv txoj cai xaim los txuas
Kev yuav cov kab hluav taws xob tuaj yeem yog txoj haujlwm txaus ntshai uas xav txog ntau yam.
Thaum yuav cov khoom sib txuas, cov neeg yuav khoom yuav tsum xav txog cov hauv qab no:
voltage
Rau ntau qhov laj thawj nws tseem ceeb heev uas yuav tsum xaiv cov xaim raug cai lossis cable rau qhov xav tau voltage, qee qhov yuav tsum muaj xws li:
- Lub thickness ntawm cov hlau ho muaj feem xyuam rau cov kuj; siab dua ua kom muaj cua sov ntau dua; Yog li ntawd, qhov ntsuas hluav taws xob tsis raug tuaj yeem tsim teeb meem kev nyab xeeb thiab hluav taws kub.
- Lub hwj chim hauv cov hlau tuaj yeem poob mus ntev; yog li kev xaiv ib lub cable uas txwv tsis pub muaj txoj hauv kev los yog ua kom nws tsis poob qis dua qhov kev lees paub yog qhov tseem ceeb.
amperage
Qhov no yog tus nqi ntawm lub zog siv los ntawm cov khoom siv hluav taws xob thiab ntsuas hauv amperes. Nws yog ib qho tseem ceeb heev uas yuav tsum paub ntau npaum li cas tam sim no nyob rau hauv cov hlau yuav raug kos los ntawm txhua yam khoom siv thaum txiav txim siab seb yuav siv cov hlau twg. Yog tias cov xaim xaiv los yog cable qis dua qhov xav tau rau lub kaw lus, cov teeb meem xws li overheating thiab melting ntawm cov hlau yuav tshwm sim.
overload qhov no yog lwm qhov teeb meem thaum muaj ntau yam khoom siv txuas nrog rau hauv Circuit Court. Nyob rau hauv cov ntaub ntawv no, lub tshuab yuav tsis ua hauj lwm kom raug vim hais tias lub Circuit Court breakers yuav mus thiab lov tes taw lub cuab yeej.
kab ntsuas
American Wire Gauge (AWG) yog tus qauv hluav taws xob thaiv hluav taws xob uas ntsuas cov xov hlau tsis muaj / stripped. Qhov txo qis hauv txoj kab uas hla yog sib npaug ntawm qhov nce hauv caliber.
Deg cheeb tsam, muab nyob rau hauv mm2, yog lwm txoj kev rau kwv yees hlau thickness. Thaum muaj ntau qhov tam sim no yuav tsum tau nqa mus rau hauv ib lub voj voog, txoj kab uas hla loj dua yog siv. Cov xaim ntev ntev tuaj yeem siv rau hauv qhov system vim tias cov hlau tam sim no ntws yooj yim dua los ntawm cov hlau tsis muaj qhov tsis muaj zog.
Rwb thaiv tsev
Lub rwb thaiv tsev yuav tsum tiv taus ntau yam xwm txheej, ntxiv rau kev sib cais lub zog ntawm lwm tus neeg xyuas pib thiab hauv av. Ib yam uas yuav tsum xav txog yog raug tshuaj lom neeg los ntawm ib puag ncig. Qhov muaj pes tsawg leeg ntawm cov rwb thaiv tsev cuam tshuam rau kwv yees kev pab cuam lub neej ntawm cov khoom kho vajtse.
Ntau cov xov hlau yog insulated nrog cov khoom siv PVC zoo los tiv thaiv tus neeg xyuas pib los ntawm kev puas tsuaj thiab luv luv. PVC tuaj yeem yaj hauv qhov kub thiab txias. Nyob rau hauv cov ntaub ntawv no, ib tug muaj zog insulating khoom xws li fluorine los yog silicone yuav tsum tau.
Cov xov hlau txuas muaj nyob rau hauv ntau yam ntaub ntawv insulating xws li PVC, PTFE, EPDM (ethylene propylene diene elastomer), hypalon, neoprene thiab silicone roj hmab. (1)
Hook-Up hlau thiab nws qhov zoo
Kev sib txuas ntawm cov xov hlau yog siv rau hauv ntau yam khoom, khoom siv thiab tsheb. Nov yog qee qhov txiaj ntsig ntawm kev siv hom tooj liab hlau rau koj qhov project:
- tooj liab hlau muaj lub siab tshaj plaws thermal conductivity ntawm tag nrho cov hlau.
- tooj liab hlau muaj siab corrosion kuj vim nws cov tshuaj tiv thaiv tsis tshua muaj nqi, tshem tawm qhov kev xav tau ntawm cov nqi hloov raws sij hawm.
- Lwm qhov tshwj xeeb ntawm kev sib txuas ntawm cov hlau yog nws qhov yooj yim, uas txhais tau hais tias nws tuaj yeem hloov pauv tau yooj yim yam tsis muaj snapping, uas yog qhov tseem ceeb heev hauv cov xwm txheej hluav taws xob uas cov hlau yuav tsum qhwv ib ncig ntawm cov ces kaum. (2)
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Cov hlau twg yog los ntawm lub roj teeb mus rau qhov pib
