Acereare Electric tshiab ARM5 series ob zaug tawg yas-cov ntaub ntawv Circuit Court breaker
I. Cov khoom saib xyuas
ARM5 series molded rooj plaub ob-tawg Circuit Court breaker yog ib yam khoom tshiab tsim los ntawm peb lub tuam txhab. Nws cov qauv tsim qhia txog qhov tseeb tam sim no txwv txoj cai thiab kev tsim cov thev naus laus zis, thiab muaj kev cog lus, modular, siab tawg, xoom arcing, ntsuab thiab ib puag ncig tiv thaiv yam ntxwv. Lub Circuit Court breaker yog tsim rau AC 50Hz / 60Hz Circuit Court nrog cov ntsuas hluav taws xob hluav taws xob ntawm 1000V, qhov siab tshaj plaws ua haujlwm voltage ntawm 690V, siab tshaj plaws tawg muaj peev xwm icu thiab ics txog li 200kA thiab ntsuas tam sim no ntawm 32A txog 630A los ua, tawg thiab nqa cov ntsuas tam sim no, thiab nws tuaj yeem txhim khu kev tiv thaiv kab thiab cov khoom siv hluav taws xob nyob rau hauv rooj plaub ntawm overload, luv Circuit Court thiab undervoltage. Nws kuj tseem siv tau rau kev pib tsis tshua muaj, overload, luv luv Circuit Court thiab kev tiv thaiv hluav taws xob ntawm lub cev muaj zog.
II. Cov khoom zoo / cov ntsiab lus muag
1. ARM5 series tau txuas ntxiv txhim kho kev ntseeg tau ntawm cov khoom siv hluav taws xob, thiab muaj qhov zoo ntawm modularization, me me, muaj peev xwm tawg siab, luv arcing, kev ntseeg siab, kev tiv thaiv ib puag ncig zoo, kev ua haujlwm zoo, thiab lwm yam.
2. luv-circuit breaking peev xwm ntawm AC400V, L hom: 100KA, M hom: 150KA, H hom: 200KA. 100KA yog siv rau cov ntawv thov kev ua haujlwm siab, cov kab ntau lawm, thiab cov khoom siv hluav taws xob tseem ceeb. 150KA-200KA muaj kev lag luam-ua kev tawg muaj peev xwm thiab tuaj yeem siv rau hauv kev lag luam hnyav thiab kev lag luam tshwj xeeb.
3. Cov khoom siv no tuaj yeem yooj yim ntsia tau rau hauv txoj haujlwm sib txuas ntawm lub tshuab hluav taws xob thiab muaj kev ua haujlwm ruaj khov. Lub shunt tso tawm, undervoltage tso tawm thiab pab tiv tauj yog tag nrho ua rau hauv nyias modules.
4. Lub thermal magnetic tso tawm ntawm ARM5-160, 250, 400 thiab 630 Circuit Court breakers tuaj yeem hloov kho kom tau raws li kev tiv thaiv.

Main functions thiab nta
I. Pneumatic tiv thaiv ntaus ntawv
Thaum lub voj voog tawg nrog cov tam sim no loj, cov roj hauv lub thawv sib txuas tau nrawm nrawm, thiab cov cuab yeej tiv thaiv pneumatic nrawm nrawm nrawm rau kev ua haujlwm ntawm lub tshuab latch nyob rau hauv cov huab cua muaj zog, txo qhov kev puas tsuaj ntawm qhov tawg tam sim no rau lwm cov khoom siv hluav taws xob thiab cov tsheb npav.
Magnetic blow design:Tam sim no ntws los ntawm kev sib cuag ruaj khov los tsim cov khoom siv hluav taws xob, uas ua rau lub voj voog sib nqus arc nrog cov tub ntxhais hlau thiab sai sai nkag mus rau hauv lub arc extinguishing chamber nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb, uas yog conducive mus sai sai tawg tam sim no.
Cov qauv tsim nyog ntawm kev txav thiab kev sib cuag ruaj khov ua rau luv luv Circuit Court ncov tus nqi thiab lub zog ntawm cov khoom siv no I²t tsawg dua li qhov xav tau.
Lub hauv paus ntsiab lus ua haujlwm: tam sim no ntws los ntawm kev sib cuag ruaj khov 1, ntws tawm los ntawm kev sib cuag ruaj khov 2 los ntawm kev txav mus los, kev sib cuag nyiaj ruaj khov thiab kev sib cuag. Kev txav mus los sai sai disconnects nyob rau hauv qhov kev txiav txim ntawm lub zog hluav taws xob repulsion quab yuam (Holm quab yuam thiab Lorentz quab yuam) los txhim kho qhov tawg ceev.
Cua tshuab tsim: thaum lub luv luv Circuit Court loj tam sim no tshwm sim nyob rau hauv lub Circuit Court, cov roj tsim qhov chaw yuav tsim tau lwm cov roj nyob rau hauv lub siab kub ntawm lub arc, cov huab cua siab nyob rau hauv lub contact unit box nce sai heev, thiab ib tug high-ceev cua khiav tau. tau tsim los ntawm cov cua qhov hluav taws xob ntawm lub arc extinguishing chamber, uas muaj peev xwm extinguish lub arc.
