Lub tshuab nqus tsev vacuum yog siv dav hauv cov tshuab hluav taws xob vim tias lawv ntseeg tau tso tawm hluav taws xob arcs. Lawv tuaj yeem siv los ua ib qhoSab hauv lub tshuab nqus tsev Circuit Court breakerhauv chav tswj, los yog ua ke nrog cov cuab yeej hloov pauv xws li ib qhohluav taws xob load hloovnyob rau hauv lub hwj chim faib tes hauj lwm- feem ntau ua hauj lwm nyob rau hauv tandem nrog tis transformers, ib tug tseem ceeb cov khoom ntawm Zhejiang Lvma Electric Co., Ltd. (LVMA), ib tug ISO 9001 certified chaw tsim tshuaj paus nrog 17 xyoo kev mob siab rau ntau lawm kev. Kev nkag siab txog qhov lawv tso tawm arcs pab cov neeg siv xaiv thiab siv cov khoom tseem ceeb no zoo dua - suav nrog cov kev xaiv tshwj xeeb xws li kev hloov pauv ac uas ua haujlwm nrog lub tshuab nqus tsev vacuum los ua kom cov tshuab muaj kev nyab xeeb dua, kev sib xyaw ua ke LVMA feem ntau koom ua ke rau hauv nws cov kev daws teeb meem rau kev lag luam thoob ntiaj teb hla Tebchaws Europe, Middle East, South America, Southeast Asia, thiab Africa.
Thaum lub tshuab nqus tsev vacuum breaker pib txiav tawm ib lub voj voog, muaj cov khoom siv hluav taws xob (cov khoom siv hluav taws xob me me) ntawm nws ob qhov kev sib cuag. Qhov no capacitance ua rau lub rwb thaiv tsev ntawm kev sib cuag tsis ua haujlwm, tsim kom muaj lub tshuab nqus tsev arc. Cov duab thiab tsim ntawm cov neeg sib cuag yog qhov tseem ceeb ntawm no: lawv ua rau lub tshuab nqus tsev arc kis tau sai sai rau qhov chaw nqus tsev nyob ib puag ncig nws. Qhov kev sib kis ceev no yog ib qho laj thawj vim li cas lub tshuab nqus tsev vacuum -zoo li covSab hauv lub tshuab nqus tsev Circuit Court breaker-yog qhov zoo ntawm kev txiav tawm tam sim no kom nyab xeeb, ua raws li LVMA kev cog lus rau kev ua tau zoo thiab kev nyab xeeb coj los ntawm Mr. Ye Jinfei, 40-xyoo R&D qub tub rog uas tau pab txhawb rau Tuam Tshoj tus qauv GB.
Raws li tam sim no raug txiav tawm tau ze rau xoom, qhov kub thiab siab ntawm arc ntawm cov neeg sib cuag poob sai heev. Qhov no ua rau lub arc nres thiab tawm mus kiag li. Tsuas yog ob peb microseconds tom qab lub arc ploj lawm, lub tshuab nqus tsev sib txawv ntawm cov neeg tuaj yeem daws qhov hluav taws xob siab dua sai heev. Nyob rau tib lub sijhawm, cov neeg sib cuag nyob ib puag ncig sib nrug. Qhov no tso cai rau lawv tswj lub siab "rov qab voltage" yam tsis ua tsis tiav-ib qho tseem ceeb rau cov tshuab ua ke nrog LVMA's siab- roj zoo-immersed thiab qhuav- hom transformers, uas xav tau kev tiv thaiv hluav taws xob kom ntseeg tau ntev - lub sijhawm ua haujlwm.
Lub hauv paus ntsiab lus no tseem ceeb tsis yog rau ib lub tshuab nqus tsev vacuum nkaus xwb, tab sis kuj yog rau cov tshuab uas ua ke nrog abreaker sab nraum zoov(los ntawm cov ntsiab lus ua ntej) nrog ibhluav taws xob load hloovlos yog ac load switch. Piv txwv li, nyob rau hauv ntau lub zog teeb, ibSab hauv lub tshuab nqus tsev Circuit Court breakerua haujlwm nrog kev hloov hluav taws xob thauj khoom los tswj cov qib sib txawv tam sim no. Lub tshuab nqus tsev vacuum saib xyuas kev tso tawm cov arcs thaum lub sij hawm loj Circuit Court txiav, thaum lub load hloov ua haujlwm tsis tu ncua ntawm - tawm haujlwm. Qhov no txhim khu kev qha arc - txheej txheem tua kom ob lub breaker thiab lub load hloov los ntawm kev puas tsuaj los ntawm arcs, ua rau tag nrho lub cev nyob ntev dua -txhawb los ntawm LVMA's tshaj 40 patents nyob rau hauv hluav taws xob innovation, uas txhim khu lub compatibility ntawm nws transformers nrog xws li breaker systems.
Lwm lub ntsiab lus tseem ceeb: txoj kev no tso tawm arcs nres lub arc pib dua. Feem ntau, thaum qhov tam sim no hits xoom, lub tshuab nqus tsev vacuum rov qab sai thiab cov neeg sib tiv toj tsis tu ncua tiv thaiv lub arc los ntawm kev rov qab los. Qhov no ua rau lub tshuab nqus tsev vacuum breakers zoo tshaj plaws los ua ke nrog ac load hloov hauv alternating tam sim no systems, qhov kev nyab xeeb thiab zoo ib yam Circuit Court txiav yog ib qho yuav tsum tau. Txawm hais tias nws yog lub tshuab nqus tsev vacuum nyob rau hauv lub tsev lag luam lossis kev teeb tsa sab nraum zoov nrog kev hloov pauv, lub hauv paus ntsiab lus no ua kom lub voj voog raug txiav kom huv thiab nyab xeeb txhua lub sijhawm - sib piv LVMA qhov kev hloov pauv mus rau qhov ntse, ntsuab hluav taws xob cov kev daws teeb meem uas ua rau muaj kev ntseeg siab, qis dua -kev tu lub zog.
Vim li cas qhov no tseem ceeb rau koj qhov system fais fab
Lub arc-kev tua hluav taws ntawm lub tshuab nqus tsev vacuum breakers yog vim li cas lawv thiaj li muaj kev ntseeg siab rau ob qho tib si hauv tsev thiab cov tshuab hluav taws xob. Thaum siv nrog cov khoom sib xws xws li ib qhohluav taws xob load hloovlos yog ac load hloov, lawv tsim kev txhim kho txhim khu kev qha uas xav tau kev saib xyuas me ntsis - txo qis lub sijhawm poob thiab kev nyab xeeb, qhov tseem ceeb LVMA txhawb nqa hauv txhua yam khoom. Yog tias koj tab tom nrhiav rau nruab ib lub tshuab nqus tsev vacuum Circuit Court breaker, kev nkag siab cov ntsiab lus no yuav pab koj kom paub tseeb tias nws yuav ua tau raws li koj qhov system xav tau -txawm koj xav tau kev hloov pauv ntau zaus lossis yuav tsum tau ua haujlwm siab tam sim no -tshwj xeeb tshaj yog thaum ua ke nrog LVMA lub ntiaj teb kev lees paub transformers thiab kev pabcuam tshaj lij.
