Kev Siv Ntau Yam Ntawm Cov Hlau Hlau: Ib Tus Neeg Siv Khoom tseem ceeb txhawb nqa lub zog thiab kev lag luam

Vim nws cov qauv yooj yim thiab zoo heev conductivity, liab qab hlau plays lub luag hauj lwm tseem ceeb nyob rau hauv tam sim no kis tau tus mob thiab teeb liab taw qhia nyob rau hauv ntau lub teb. Txawm hais tias tsis muaj rwb thaiv tsev, raws li kev tsim qauv thiab kev siv, cov hlau liab qab tuaj yeem ruaj khov thiab ua haujlwm zoo rau kev xa tawm hluav taws xob thiab kev xa tawm, cov cuab yeej siv, thiab cov xwm txheej tshwj xeeb engineering, dhau los ua ib qho tseem ceeb ntawm cov khoom siv niaj hnub no.

Hauv cov tshuab hluav taws xob, cov hlau liab qab yog qhov tseem ceeb ntawm cov kab hluav taws xob siv hluav taws xob. Siv cov rwb thaiv tsev thiab kev nyab xeeb tsim los ntawm ntauwd qauv, txhuas thiab hlau -cored aluminium stranded liab qab hlau tuaj yeem xa hluav taws xob hluav taws xob mus ntev thiab muaj peev xwm siab, sib txuas qhov zoo ntawm lub teeb yuag thiab siab zog, txo txoj kab kev tsim kho thiab kho cov nqi. Copper lossis aluminium liab qab hlau kuj yog feem ntau siv nyob rau hauv busbars nyob rau hauv tis tes hauj lwm kom ua tau siab tam sim no sau thiab faib nrog tsawg impedance, kom ntseeg tau lub hwj chim mov.

Nyob rau hauv kev lag luam sector, qhov kev thov rau liab qab hlau yog reflected nyob rau hauv ob qho tib si sab hauv thiab sab nrauv fais fab kev sib txuas. Cov motors loj, transformers, thiab switchgear feem ntau siv cov hlau liab qab los ua cov windings lossis cov neeg caij npav kom txo tau lub zog poob thiab txhim kho cov cua sov kom zoo. Hauv cov kab ntau lawm thiab nqa cov cuab yeej siv, ntau - cov xov hlau tsis muaj hlua khi tuaj yeem hloov kho tau yooj yim los ua raws li cov neeg kho tshuab txav, kom ntseeg tau tias muaj cov khoom siv hluav taws xob tsis tu ncua thiab tswj cov teeb liab. Nyob rau hauv siab - kub los yog corrosive ib puag ncig xws li smelting thiab tshuaj industries, plated los yog alloyed liab qab nyob ntawm tej yog nyiam los tiv thaiv corrosive los ntawm hnyav ua hauj lwm tej yam kev mob.

Cov xov hlau liab qab kuj muaj cov ntawv thov tseem ceeb hauv kev sib txuas lus thiab kev tsim kho tshwj xeeb. High-ntau zaus kav hlau txais xov feem ntau siv tooj liab liab xov hlau los tsim cov ntsiab lus hluav taws xob, kom ntseeg tau tias tsis tshua muaj teeb liab poob thiab ua haujlwm siab hauv cov teeb liab kis tau tus mob. Qee qhov kev sim thiab kev tshawb fawb cov cuab yeej siv cov xov hlau tsis muaj hluav taws xob ncaj qha los ua cov dej ntws loj lossis siab - zaus pulses, ua kom yooj yim cov qauv hauv Circuit Court thiab txhim kho kev ntsuas qhov tseeb. Tsis tas li ntawd, hauv kev tsim cov qauv hlau thiab cov kav hlau txuas, lawv tuaj yeem siv los ua cov khoom sib xyaw ua ke uas sib xyaw cov khoom siv thauj khoom-cov kabmob thiab cov haujlwm hauv av.

Zuag qhia tag nrho, daim ntaub ntawv xov tooj liab qab npog ntau yam, los ntawm kev xa hluav taws xob thiab kev xa mus rau kev tsim khoom, los ntawm cov chaw sib txuas lus mus rau cov haujlwm tshwj xeeb engineering. Lawv tus nqi yog nyob rau hauv kev ua tiav kev sib kis tau zoo ntawm hluav taws xob thiab kev quab yuam nyob rau hauv txoj kev ncaj ncees tshaj plaws, txhawb kev ruaj khov ntawm ntau lub tshuab hauv lub neej niaj hnub.
