Cov Khoom Siv Hluav Taws Xob Low-Voltage vs Cov Khoom Siv Hluav Taws Xob High-Voltage: Cov Qauv Kev Cai, Kev Tsim Qauv thiab Cov Xwm Txheej Siv

Hauv lub tshuab faib hluav taws xob, cov khoom siv hluav taws xob qis thiab cov khoom siv hluav taws xob siab yog ob lub ntsiab lus tseem ceeb. Txawm hais tias ob qho tib si yog cov khoom siv hluav taws xob, lawv muaj qhov sib txawv tseem ceeb hauv cov qauv kev faib tawm, kev tsim qauv thiab cov xwm txheej siv. Kev tsis meej pem ob qho no yuav ua rau xaiv tsis raug thiab cuam tshuam rau kev nyab xeeb ntawm kev faib hluav taws xob. Tsab xov xwm no tshuaj xyuas luv luv txog qhov sib txawv tseem ceeb los muab cov ntaub ntawv siv tau rau cov kws kho mob.

I. Tus Txheej Txheem Kev Cai: Qhov Ntsuas Hluav Taws Xob Kom Tseeb

Qhov kev faib tawm tseem ceeb ntawm ob qho no yog qhov ntsuas hluav taws xob, uas tau teev meej meej hauv cov qauv kev lag luam thoob ntiaj teb (IEC, GB): qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob qis yog ≤1000V AC thiab ≤1500V DC, nrog rau cov hluav taws xob feem ntau ntawm 220V thiab 380V, koom nrog qhov kawg ntawm kev faib hluav taws xob; qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob siab yog ＞1000V AC thiab ＞1500V DC, nrog rau cov hluav taws xob feem ntau ntawm 10kV, 35kV thiab siab dua, koom nrog qhov txuas kis. Peb lub tuam txhab cov khoom tseem ceeb yog cov khoom siv hluav taws xob, uas suav nrog cov hluav taws xob qis (MCB, MCCB) thiab cov hluav taws xob nruab nrab-siab, tsim nyog rau ntau qhov xwm txheej sib txawv.

II. Kev Tsim Qauv: Cov Kev Xav Tau Tseem Ceeb Sib Txawv

Cov khoom siv hluav taws xob qis siv "kev nyab xeeb, yooj yim thiab pheej yig" ua lub hauv paus. Tus qauv tsim tsom mus rau kev rwb thaiv tsev yooj yim, kev teeb tsa yooj yim thiab kev tiv thaiv overload / luv luv, nrog rau cov qauv yooj yim thiab tus nqi tswj tau; cov khoom siv hluav taws xob siab siv "kev rwb thaiv tsev, arc tua hluav taws xob thiab kev ruaj khov" ua lub hauv paus. Vim yog lub zog loj ntawm cov hluav taws xob siab arcs, nws yog qhov tsim nyog los txhim kho cov rwb thaiv tsev thiab arc tua hluav taws xob (xws li SF6 thiab vacuum arc tua hluav taws xob), nrog rau cov qauv nyuaj thiab cov txheej txheem xav tau siab.

III. Cov Xwm Txheej Thov: Kev Hloov Kho Thaum Xav Tau

Cov khoom siv hluav taws xob qis-voltage yog siv rau kev faib hluav taws xob kawg, ze rau cov neeg siv, feem ntau pom muaj nyob rau hauv cov tsev nyob, cov tsev ua haujlwm thiab cov chaw tsim khoom me me, faib hluav taws xob rau cov khoom siv kawg; cov khoom siv hluav taws xob siab-voltage yog siv rau kev xa hluav taws xob thiab kev hloov pauv chaw, feem ntau pom muaj nyob rau hauv cov chaw hloov pauv, cov chaw tsim hluav taws xob loj thiab cov chaw tsim khoom lag luam loj, lub luag haujlwm rau kev xa hluav taws xob siab-voltage thiab kev tiv thaiv kauj ruam-down.

Kev Txheeb Xyuas

Qhov txawv ntawm ob qho no yog vim qib hluav taws xob. Cov khoom siv hluav taws xob qis-voltage tsom mus rau qhov yooj yim thiab siv tau, ua haujlwm rau lub davhlau ya nyob twg; cov khoom siv hluav taws xob siab-voltage tsom mus rau kev nyab xeeb thiab kev ruaj khov, tswj lub hub. Kev piav qhia meej txog ciam teb tuaj yeem pab xaiv qhov tseeb thiab zam kev phom sij rau kev nyab xeeb.

Peb yuav txuas ntxiv qhia cov kev paub txog cov khoom siv hluav taws xob thiab muab ntau cov ntaub ntawv xaiv rau yav tom ntej.
