Lub hauv paus chiv keeb thiab kev loj hlob ntawm Distribution Boxes

Lub hauv paus chiv keeb ntawm Distribution Boxes
Raws li cov tshuab hluav taws xob txuas ntxiv mus, qhov xav tau tshwm sim rau cov khoom siv hluav taws xob uas muaj kev yooj yim dua thiab kev nyab xeeb rau kev faib thiab tswj hluav taws xob. Los ntawm lub xyoo pua puv 19, cov vaj huam sib luag faib tau pib siv dav hauv cov chaw soj ntsuam thiab cov tshuab hluav taws xob me me -. Tom qab ntawd, raws li cov tshuab hluav taws xob tau nthuav dav thiab kev siv cov khoom siv hluav taws xob tau nce zuj zus, muaj qhov xav tau sai rau cov cuab yeej siv tau zoo dua thiab ruaj ntseg los tswj kev faib hluav taws xob thiab kev tswj hwm. Xyoo 1898, Westinghouse Electric Company hauv Tebchaws Meskas tau tshaj tawm thawj tiam ntawm cov thawv xa khoom, yog li tso lub hauv paus rau kev txhim kho yav tom ntej ntawm cov thev naus laus zis no.

 

Lub Evolution ntawm Distribution Boxes
Nyob ib ncig ntawm 1900, nrog kev nce ntxiv ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntau ntxiv - thiab qhov ua rau muaj kev nyuaj siab ntawm cov tshuab fais fab - qhov xav tau ntau dua tau muab tso rau ntawm qhov ua tau zoo thiab kev ntseeg siab ntawm cov thawv xa khoom. Yog li ntawd, ntau lub tuam txhab hluav taws xob tau pib tsim cov khoom lag luam xa tawm tshiab, suav nrog cov thev naus laus zis tshiab xws li hluav taws xob motors thiab fuses los txhim kho kev ua haujlwm zoo thiab kev nyab xeeb.

 

Thaum lub sijhawm xyoo 1950 thiab 1960, tau tsav los ntawm kev loj hlob sai ntawm kev lag luam tshuab thiab hluav taws xob, kev sib kis thiab kev siv tshuab thev naus laus zis kuj tau nce nrawm heev. Cov thawv faib khoom pib hloov zuj zus mus rau kev txawj ntse thiab automation, maj mam sib koom ua ke cov thev naus laus zis tshiab- xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob- txhawm rau txhim kho lawv qib ntawm kev ua haujlwm ntse thiab kev tswj tsis siv neeg.

 

Qhov tseem ceeb ntawm Distribution Boxes
Cov thawv xa khoom niaj hnub no tau dhau los ua ib qho tseem ceeb ntawm cov tshuab hluav taws xob, nrhiav kev siv dav hauv ntau hom kev lag luam, suav nrog kev lag luam, thaj chaw, thiab chaw lag luam. Cov thawv xa khoom ua haujlwm tseem ceeb-xws li kev sib txuas hauv Circuit Court, luv luv- tiv thaiv kev tiv thaiv hluav taws xob, tiv thaiv kev xau, thiab kev tiv thaiv overload- yog li ua kom muaj kev ruaj ntseg thiab ruaj khov. Tsis tas li ntawd, cov thawv ntim khoom siv niaj hnub no muaj peev xwm txawj ntse- xws li kev soj ntsuam cov chaw taws teeb thiab kuaj xyuas qhov tsis raug- uas ua rau muaj txiaj ntsig zoo rau ob qho tib si kev ntseeg siab thiab cov neeg siv- kev phooj ywg ntawm lub zog hluav taws xob.
