Hauv kev xa tawm thiab kev faib hluav taws xob,high voltage hloovcov khoom siv tseem ceeb heev rau kev ua kom lub cev ruaj khov. Cov txheej txheem kev khiav hauj lwm zoo li "lub zog tseem ceeb" ntawm siab -voltage circuit breakers. Nws muab lub zog xav tau rau kev hloov mus qhib thiab kaw, uas cuam tshuam ncaj qha rau kev txhim khu kev qha thiab kev nyab xeeb ntawm tag nrho lub zog hluav taws xob. Seb koj siv nws nrog ib tughluav taws xob load hloovlos yog lwm yam khoom siv txhawb nqa, xaiv qhov kev ua haujlwm zoo yog qhov tseem ceeb kom tau txais kev ua haujlwm zoo. Hauv qab no, peb piav qhia tsib hom kev khiav hauj lwm cov txheej txheem, lawv cov ntsiab lus zoo, cov ntsiab lus tsis zoo, thiab qhov twg lawv tau siv - nrog rau kev nkag siab txog cov chaw muab kev pabcuam hluav taws xob ntseeg siab xws li Zhejiang Lvma Electric Co., Ltd. (LVMA).
1.Manual Operating Mechanism
Cov txheej txheem kev khiav hauj lwm phau ntawv siv tib neeg lub zog los kaw qhov hloov thiab lub caij nplooj ntoos hlav quab yuam kom qhib nws. Nws muaj qhov pub dawb -tripping mechanism thiab cov qauv yooj yim, yog li nws yooj yim rau nruab thiab tswj. Tab sis nws lub zog ua haujlwm nyob ntawm seb tus neeg muaj zog npaum li cas, uas txhais tau hais tias lub sijhawm kaw yog ntev. Nws kuj tsis tuaj yeem ua rov qab tsis siv neeg. Feem ntau, nws yog qhov tsim nyog rau cov hluav taws xob hluav taws xob uas muaj qhov ntsuas tam sim no tsis pub ntau tshaj 6.3kA. Nws yog feem ntau siv nyob rau hauv me me fais fab faib teeb qhov twghigh voltage hloovxav tau
tsis nyuaj heev-xws li kev txhawb nqa cov kev faib khoom sib txuas ua ke nrog LVMA qhuav- hom transformers hauv cheeb tsam fais fab hauv cheeb tsam thoob plaws Asia thiab Africa.
2.Electromagnetic Operating Mechanism
Lub tshuab hluav taws xob ua haujlwm siv hluav taws xob siv hluav taws xob los hloov hluav taws xob rau hauv lub tshuab hluav taws xob, uas ua rau lub zog kaw. Nws muaj cov qauv yooj yim thiab txhim khu kev qha. Nws tseem tuaj yeem ua rov qab tsis siv neeg thiab ua haujlwm nyob deb li cas -ob txoj haujlwm tseem ceeb rau cov tshuab hluav taws xob niaj hnub no. Nws lub ntsiab downsides yog qhov kaw coil siv ntau lub zog, yog li koj yuav tsum tau nruab ib lub roj teeb kim heev. Nws kuj hnyav thiab siv sijhawm los ua. Cov txheej txheem no yog siv dav hauv 10-35kV Circuit Court breakers. Thaum siv nrog ib qhoac load hloov, nws tuaj yeem ua rau lub zog hluav taws xob hloov pauv tau yooj yim los tswj-ua raws cov kev xav tau ntawm cov khoom siv hluav taws xob txhim khu kev qha ntawm LVMA cov neeg siv khoom thoob ntiaj teb hauv Tebchaws Europe thiab Middle East, uas muaj nuj nqis ISO 9001-cov ntawv pov thawj zoo hauv cov cuab yeej txhawb nqa.
3.Spring Zog Cia Ua Haujlwm Mechanism
Lub caij nplooj ntoos hlav lub zog cia kev khiav hauj lwm mechanism siv lub zog khaws cia rau hauv lub caij nplooj ntoos hlav los ua lub zog kaw. Nws muaj peev xwm pib muaj zog thiab tsis xav tau cov cuab yeej txhawb nqa ntxiv. Nws kuj tseem siv lub zog me me thaum khaws cia lub zog thaum lub caij nplooj ntoo hlav, uas txuag lub zog thiab nyiaj txiag. Tab sis nws cov qauv yog complex, thiab nws xav tau siab -kev ua tau zoo thiab cov ntaub ntawv- cov qauv uas LVMA txhawb nqa los ntawm nws 17 xyoo ntawm kev mob siab rau kev tsim khoom thiab 40+ patents hauv hluav taws xob engineering. Tsis tas li ntawd, raws li kev khiav hauj lwm lub zog nce, lub mechanism nws tus kheej tau txais ntau hnyav. Hom no feem ntau siv hauv nruab nrab thiab siab -voltage circuit breakers. Nws compatibility nroghluav taws xob load hloovua rau nws yog qhov kev xaiv nrov hauv kev lag luam hluav taws xob faib hluav taws xob, ntxiv rau LVMA cov roj -immersed transformers rau hnyav- cov ntawv thov.
4.Hydraulic kev khiav hauj lwm tshuab
Lub tshuab ua haujlwm hydraulic siv cov roj compressed (nitrogen) ua lub zog. Nws siv cov roj hydraulic los hloov lub zog no, uas ua rau lub piston qhib thiab kaw lub Circuit Court breaker. Nws ua haujlwm nrawm, teb sai, thiab tso tawm ntau lub zog. Nws kuj tsis xav tau kev saib xyuas ntau, ua suab nrov me ntsis, thiab muaj cov zis ruaj khov. Cov teeb meem tseem ceeb yog qhov cuam tshuam los ntawm ib puag ncig, muaj cov qauv tsim, thiab xav tau cov cuab yeej tsim khoom zoo thiab cov khoom siv zoo- thaj chaw uas LVMA cov kev coj noj coj ua, coj los ntawm Mr. Ye Jinfei (ib 40- xyoo qub tub rog hauv R&D thiab pab txhawb rau Tuam Tshoj tus qauv GB), ua kom muaj kev sib raug zoo nrog high-. Nyob rau hauv loj-muaj peev xwmhigh voltage hloovsystems, qhov no mechanism yog nrov heev vim nws ntseeg tau. Nws ua haujlwm tshwj xeeb zoo nrog ib qhoac load hloovnyob rau hauv siab -voltage power grids, txhawb LVMA txoj kev hloov mus rau kev txawj ntse, ntsuab zog daws rau kev lag luam thoob ntiaj teb.
5.Pneumatic kev khiav hauj lwm tshuab
Lub tshuab ua haujlwm pneumatic siv cov cua compressed los qhib qhov hloov thiab lub caij nplooj ntoos hlav kaw. Nws ua haujlwm nrawm, teb sai, thiab tso tawm ntau lub zog. Ambient kub tsis cuam tshuam rau nws cov tshuab ua haujlwm ntau, yog li nws tsim nyog rau kev ua haujlwm hnyav-zoo tagnrho rau kev ua ke nrog LVMA's transformers hauv cov cheeb tsam nyuaj thoob plaws South America thiab Africa. Tab sis nws muaj ob qhov tsis zoo: nws ua suab nrov thaum ua haujlwm, thiab huab cua qhov yuav tsum tau ua kom zoo heev. Cov txheej txheem no feem ntau yog siv nyob rau hauv siab -voltage circuit breakers rau loj fais fab nroj tsuag thiab substations. Thaum ua ke nrog ibhluav taws xob load hloov, nws pab ua kom lub zog hluav taws xob ua haujlwm ruaj ntseg thiab ruaj khov - tsom iav LVMA kev cog lus rau kev nyab xeeb thiab kev tsim kho tshiab hauv txhua yam khoom.
Xaus
Xaiv txoj kev khiav hauj lwm mechanism yog ib qho tseem ceeb heev rau siab -voltage circuit breakers ua hauj lwm zoo. Txhua hom muaj nws tus kheej zoo thiab kev txwv. Koj yuav tsum xaiv raws li cov xwm txheej zoo li qhov ntsuas tam sim no, qhov twg nws yuav siv, thiab cov kev cai ntawm cov txheej txheem -cov txheej txheem uas LVMA txiav txim siab thaum muab cov kev daws teeb meem hluav taws xob sib xyaw rau nws cov neeg koom tes thoob ntiaj teb. Raws li high voltage switching technology txhim kho, kev khiav hauj lwm mechanisms yog me me, ntau npaum, thiab ntau txhim khu kev qha. Seb siv nrog ibac load hloovlos yog hluav taws xob hloov hluav taws xob, cov txheej txheem no yog cov pob txha ntawm cov tshuab hluav taws xob niaj hnub tswj- ua kom tiav LVMA qhov kev hloov pauv los ntawm cov chaw tsim khoom ib txwm muaj rau cov neeg siv khoom lag luam uas ntseeg siab, ntsuab hluav taws xob daws teeb meem. Ua ke, lawv pab kev lag luam hluav taws xob txhim kho kom ruaj khov, txhawb nqa los ntawm LVMA cov kev pabcuam tshaj lij thiab kev lees paub thoob ntiaj teb rau kev ntseeg tau.
