High-voltage circuit breakers yog qhov tseem ceeb ntawm cov hluav taws xob faib hluav taws xob, thiab lawv txoj haujlwm txhim khu kev qha nyob ntawm ntau yam ntawm lawv cov txheej txheem khiav haujlwm. Raws li ib feem tseem ceeb ntawm cov khoom siv hluav taws xob, cov txheej txheem kev khiav hauj lwm tswj cov kev sib txuas ntawm lub voj voog, kaw, thiab ua kom nws kaw - qhov no cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm ntawm kev xa hluav taws xob. Zhejiang Lvma Electric Co., Ltd. (LVMA) yog ISO 9001 certified chaw tsim tshuaj paus nrog 17 xyoo ntawm kev paub nyob rau hauv lub hwj chim faib khoom. Peb paub tias cov txheej txheem no tseem ceeb npaum li cas thaum siv nrog transformers thiab hloov qhov chaw. Hauv tsab xov xwm no, peb yuav piav qhia txog cov kev cai tseem ceeb thiab cov qauv kev ua haujlwm ntawm lub tshuab no, thiab tseem tham txog yuav ua li cas nws ua haujlwm nrog cov khoom muaj feem xyuam xws lihigh voltage hloov, hluav taws xob load hloov, thiab sab nraum zoov high voltage rho tawm hloov.
Cov ntsiab lus tseem ceeb rau kev siv tshuab
Lub zog ua haujlwm txaus
Lub tshuab yuav tsum muaj lub zog txaus los qhib thiab kaw lub siab -voltage circuit breaker, txawm tias thaum lub load hnyav. Nws kuj yuav tsum tau ua kom lub kaw lus ceev txaus. Qhov no tseem ceeb heev rau high voltage switching systems. Smooth fais fab hloov ntawm qhov chaw tiv thaiv qhov teeb meem voltage thiab khoom puas.High voltage hloovtso siab rau lub tshuab fais fab los hloov circuits smoothly, yog li qhov kev xav tau no yog qhov yooj yim rau tag nrho lub cev ua haujlwm zoo. Nws kuj tseem ua raws li LVMA qhov kev cog lus rau cov kev daws teeb meem kev faib hluav taws xob muaj txiaj ntsig zoo -peb pab kev lag luam thoob plaws Europe, Middle East, Southeast Asia, thiab ntau dua.
Kev ntseeg siab
Lub tshuab ua haujlwm yuav tsum teb sai sai, tsis yog pib los ntawm kev sib tsoo, thiab tsis txhob plam ib qho kev ua haujlwm tsim nyog. Thaum twghluav taws xob load hloovpab kiag li lawm yog ib feem ntawm lub hwj chim network, lub mechanism ntawm kev cia siab rau ncaj qha cuam tshuam qhov zoo ntawm tus tes hloov qhov tam sim no ntws. Ib qho hluav taws xob hloov hluav taws xob feem ntau ua haujlwm nrog cov hluav taws xob hluav taws xob los tswj cov khoom ib nrab. Lub tshuab ua haujlwm muaj kev cia siab tau ua kom lub qhov hloov pauv tuaj yeem qhib lossis kaw yam tsis tau ncua sijhawm - qhov no yog qhov tseem ceeb kom tsis txhob muaj overloads thiab txo qis sijhawm. Tsis tas li ntawd, thaum ua ke nrogsab nraum zoov high voltage cais hloovunits, lub tshuab kev ntseeg tau khaws cov circuits kom muaj kev nyab xeeb ntawm kev sib cais thaum tu, tiv thaiv cov neeg ua haujlwm thiab cov khoom siv. Qhov kev tsom mus rau kev ntseeg tau zoo ib yam li LVMA txoj hauv kev: peb tau coj los ntawm Mr. Ye Jinfei, tus kws tshaj lij R&D 40 xyoo uas tau pab tsim Tuam Tshoj tus qauv GB, thiab peb siv zog ua kom muaj kev nyab xeeb, zoo ib yam khoom.
Anti-Dhia muaj nuj nqi
Kev tiv thaiv- yuav tsum muaj kev tiv thaiv dhia kom txwv tsis pub lub Circuit Court breaker los ntawm kev qhib thiab kaw ntau dua thaum muaj qhov ua txhaum. Muaj ob txoj hauv kev los ua qhov no: hluav taws xob (ntxiv rau kev tiv thaiv- dhia relays hauv kev tswj circuits) thiab txhua yam (nruab cov khoom tso tawm dawb). Txoj haujlwm no tseem ceeb tshwj xeeb tshaj yog thaum lub Circuit Court breaker txuas nrog ib qhohluav taws xob load hloov, vim tias kev dhia tsis tau npaj txhij tuaj yeem ua rau muaj teeb meem lossis ua rau lub chaw hloov pauv kev sib cuag. Rausab nraum zoov high voltage cais hloovdaim ntawv thov, tiv thaiv- cov txheej txheem dhia tiv thaiv kev sib tsoo ntawm cov kab hluav taws xob sib cais- ua rau lawv muaj kev nyab xeeb dua los siv hauv cov xwm txheej sab nraum zoov. LVMA muaj ntau dua 40 patents hauv cov cuab yeej siv hluav taws xob tshiab, uas pab txhawb kev sib koom ua ke ntawm cov yam ntxwv zoo li no hauv cov tshuab hluav taws xob.
Kaw thiab kaw tuav
Lub tshuab yuav tsum ua kom tau raws li qhov kev xav tau ntawm Circuit Court breaker qhov kev xav tau ceev, ua kom nws kaw ruaj khov ob qho tib si nyob rau hauv ib txwm muaj thiab luv luv - Circuit Court txhaum. Tom qab kaw, nws yuav tsum ua kom cov neeg raug kaw kom ruaj khov, txawm tias luv luv - lub zog hluav taws xob hluav taws xob, cua, av qeeg, lossis teeb meem tsis sib haum xeeb. Qhov kev ruaj ntseg no tseem ceeb heev rausab nraum zoov high voltage cais hloovtshuab. Sab nraum zoov ib puag ncig nthuav tawm cov khoom rau huab cua huab cua, yog li lub tshuab yuav tsum ua kom cov neeg sib cuag tsis muaj teeb meem dab tsi. Sab nraum zoov hluav taws xob hluav taws xob hluav taws xob hloov hluav taws xob nyob ntawm qhov chaw nres tsheb kaw kom nyob ib leeg thaum xav tau, yog li qhov kev xav tau no yog qhov tseem ceeb rau kev siv mus sij hawm ntev - sab nraum zoov. Nws phim LVMA tsom rau cov roj ruaj khov- raus thiab qhuav- hom transformers- peb cov khoom tau tsim los ua haujlwm zoo hauv txhua qhov chaw thoob ntiaj teb.
Kev Ua Haujlwm
Kev mus ncig ua si yuav tsum ua raws li cov txheej txheem ceev thiab sijhawm. Kev txav mus los yuav tsum qhib rau qhov kev ncua deb thaum txo qhov cuam tshuam thiab kev co. Lub tshuab yuav tsum lees txais tsis siv neeg lossis tej thaj chaw deb hluav taws xob mus txawv tebchaws, thiab tseem tso cai rau kev taug kev mus rau qhov xwm txheej ceev. Qhov kev hloov pauv no ua haujlwm zoo nroghigh voltage hloovsystems- nrawm nrawm thaum lub sijhawm ua txhaum cai tiv thaiv ob lub tshuab tawg thiab cov khoom siv hloov pauv. Kev hloov pauv hluav taws xob siab tso siab rau lub sijhawm mus txawv tebchaws kom tsis txhob muaj kev ua tsis tiav, yog li lub tshuab ua haujlwm txhim khu kev qha yog qhov tseem ceeb ntawm kev nyab xeeb.
Kev ua tiav ntawm cov lus txib & Anti-Dhia/Free Trip
Qhib thiab kaw yuav tsum du, nrog ruaj khov buffering, thiab ua tau raws li tus qauv tsim ceev. Tom qab txhua qhov kev ua haujlwm, lub tshuab yuav tsum rov pib dua tshiab kom npaj rau kev siv tom ntej, thiab xa tawm cov cim (xws li ntsuas, tswb, lossis cov lus sib cuam tshuam). Kev ua haujlwm pub dawb mus ncig ua si- nres qhov txheej txheem kaw kom qhib tam sim ntawd thaum tau txais cov lus txib qhib - tiv thaiv kev dhia. Qhov no yog qhov tseem ceeb rau cov khoom siv hluav taws xob hloov hluav taws xob. Ib qho hluav taws xob hloov hluav taws xob xav tau kev ua raws li cov lus txib kom kho cov khoom xa tawm kom zoo, thiab cov txheej txheem kev ua haujlwm kom ntseeg tau tias lawv ua haujlwm ua haujlwm zoo.
Pib dua, Lockout, thiab Zog Cia
Tom qab qhib, txhua qhov chaw ntawm lub tshuab yuav tsum rov pib dua tuaj yeem npaj tau kaw. Lockout functions-nrog rau txoj hauj lwm lockout, huab cua/hydraulic siab lockout, thiab caij nplooj ntoos hlav txoj hauj lwm lockout nyob rau hauv caij nplooj ntoos hlav-kev ua hauj lwm mechanisms- xyuas kom meej kev ruaj ntseg. Lub sij hawm cia lub zog yuav tsum phim lub voj voog ua haujlwm los txhawb kev siv tas mus li. Cov yam ntxwv no muaj txiaj ntsig zoo rau cov tshuab nrog sab nraum zoov hluav taws xob hluav taws xob hluav taws xob cais tawm hloov chaw. Lockout mechanisms tiv thaiv kev ua haujlwm tsis raug cai lossis tsis muaj kev nyab xeeb hauv thaj chaw sab nraud. Tsis tas li ntawd, kev cia lub zog kom zoo kom ntseeg tau tias lub tshuab tuaj yeem ua kom muaj kev hloov pauv hloov mus rau qhov siab, tswj kev ua haujlwm zoo thaum lub sijhawm tsis khoom. Cov no yog cov txiaj ntsig uas LVMA txhawb nqa hauv txhua yam khoom, los ntawm kev hloov pauv mus rau cov kev daws teeb meem sib xyaw ua ke.
