Khoom Description
ZW20NG-7.2/400-12.5 isolator breaker yog cov khoom siv tseem ceeb ntawm nws tus kheej tsim los ntawm peb lub tuam txhab rau kev siv hluav taws xob sab nraum zoov. Nrog rau qhov ntsuas hluav taws xob ntawm 7.2 kV, nws tsim nyog rau peb theem AC 50 Hz. Nws txais yuav qhov siab tshaj ZW20 peb-theem kev sib xyaw-kho cov qauv tsim, kev sib koom ua ke ntawm kev sib cais nyob rau hauv peb-theem ncej. Cov ncej kev sib cais yog tsim rau hauv lub thawv mechanism, thaum kev sib cais kev khiav hauj lwm kov yog sab nraud nkag tau, ua rau cov qauv compact thiab txhim kho kev ua haujlwm yooj yim.
● Lub tshuab cais tawm no txhawb nqa ob hom kev ua haujlwm hluav taws xob thiab phau ntawv, ua kom tau raws li qhov yuav tsum tau ua nyob rau hauv ntau yam kev ua haujlwm. Nws kuj tseem muaj qhov tsim kho tshiab triple txhim khu kev qha xauv lub tshuab, suav nrog kev sib cuam tshuam cov tshuab, hluav taws xob cuam tshuam, thiab NKE electromagnetic lock, hauv paus tshem tawm cov kev pheej hmoo ntawm kev ua haujlwm tsis raug thiab ua kom muaj kev nyab xeeb ntawm ob qho tib si khoom siv thiab cov neeg ua haujlwm.
● Nrog kev tiv thaiv kev ntsuas ntawm IP67, lub tshuab cais tawm tuaj yeem ua haujlwm tau zoo nyob rau hauv qhov chaw sab nraum zoov hnyav, nrog rau qhov kub thiab txias, av noo, plua plav, thiab nag hnyav. Nws muaj lub neej txhua yam ntau tshaj 10,000 lub voj voog ua haujlwm, ua kom pom kev ruaj khov ntev ntev - thiab muab kev tiv thaiv hluav taws xob txuas ntxiv thiab txhim khu kev qha rau ntau hom kev siv hluav taws xob.
● Nyob rau hauv cov ntsiab lus ntawm kev ua haujlwm tseem ceeb, lub Circuit Court breaker muab kev ua tau zoo heev. Nws muaj qhov ntsuas tam sim no ntawm 400 A, ntsuas luv luv- lub sijhawm tiv thaiv tam sim no ntawm 12.5 kA rau 1 thib ob, ntsuas luv luv -circuit breaking tam sim no tsis pub tsawg tshaj 30 kev ua haujlwm, ntsuas luv luv-circuit breaking tam sim no ntawm 12.5 kA (RMS ntawm 1){9} thiab tam sim no kA (peak). Cov kev txwv no ua kom cov lus teb sai thiab muaj kev nyab xeeb nyob rau hauv luv luv - cov xwm txheej hauv Circuit Court thiab kev ua txhaum, tiv thaiv lub zog hluav taws xob thiab cov khoom siv hauv qab.
Hais txog kev ua haujlwm rwb thaiv tsev, lub zog ntsuas - zaus tiv taus qhov hluav taws xob (1 feeb) yog 22 kV ntawm theem thiab rau hauv av, 25 kV hla lub tshuab nqus tsev cuam tshuam, thiab 35 kV hla kev sib cais cov kev sib cuag. Qhov ntsuas hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob yog 60 kV ntawm theem thiab hauv av, thiab 70 kV ntawm kev sib cuag. Qhov tsawg kawg nkaus sab nraud creepage deb tsis tsawg tshaj li 225 hli, thiab hauv av clearance yog 90 hli, kom ntseeg tau tias muaj kev ruaj ntseg rwb thaiv tsev kev ua tau zoo nyob rau hauv complex voltage tej yam kev mob.
Lub tshuab ua haujlwm tau txais lub caij nplooj ntoos hlav-loaded tsim, nrog rau kev khiav hauj lwm quab yuam ntawm 100 N txog 300 N. Lub zog rov qab los ntawm kev them nyiaj yog tsis pub tsawg tshaj 10 N, kom ntseeg tau tias kev ua haujlwm zoo thiab cov lus teb sai. Lub disconnector hloov siv ib tug ua tau - nyob rau hauv ncaj qha - qauv ua yeeb yam nrog ib tug sib chwv qhov sib txawv ntawm 60 mm, thiab nws cov kev khiav hauj lwm quab yuam kuj nyob rau hauv lub cheeb tsam ntawm 100-300 N, kom ntseeg tau yooj yim thiab ua hauj lwm zoo.
Ua tsaug rau nws cov kev ua tau zoo tag nrho, cov khoom no tau siv dav hauv cov chaw ua haujlwm sab nraum zoov, cov chaw ua si hauv chaw ua haujlwm, kev kho vaj tse hauv nroog, kev hloov kho hluav taws xob hauv zej zog, thiab kev siv hluav taws xob tshiab. Nws ua tau raws li cov qauv siv hluav taws xob sib kis thiab kev faib tawm thaum tseem muab cov khoom siv hluav taws xob txhim khu kev qha rau cov ntawv thov tshwj xeeb xws li kev sib txuas ntawm lub zog tshiab. Raws li ib qho tseem ceeb ntawm cov cuab yeej tseem ceeb hauv kev faib hluav taws xob sab nraum zoov, nws muab lub hauv paus ruaj khov rau kev nyab xeeb, ruaj khov, thiab ua haujlwm tau zoo ntawm cov khoom siv hluav taws xob.
