Low Voltage Vacuum Interrupter yog ib qho khoom siv hluav taws xob uas siv lub tshuab nqus tsev vacuum ua qhov nruab nrab ntawm qhov hluav taws xob tua hluav taws xob, nrog rau cov khoom tseem ceeb yog ib khub ntawm cov electrodes (kev sib cuag) kaw hauv lub tshuab nqus tsev thiab lwm yam. Thaum qhov tam sim no hauv Circuit Court yuav tsum raug txiav tawm, cov neeg sib cuag yuav raug sib cais thiab tsim ib qho arc ntawm lawv. Vim tias qhov tsis tshua muaj roj molecules nyob rau hauv lub tshuab nqus tsev, nws yog ib qho nyuaj rau tswj lub arc, lub arc ntawm cov neeg sib cuag yuav raug tua sai sai, kom paub qhov Circuit Court kaw los yog tawg.
Cov ntawv thov tseem ceeb
1. Tsawg voltage hluav taws xob faib qhov system:
Tsawg-voltage lub tshuab nqus tsev cuam tshuam tuaj yeem siv rau hauv ntau qhov hluav taws xob qis hluav taws xob, xws li hluav taws xob hluav taws xob hluav taws xob hluav taws xob, hluav taws xob tsis tshua muaj hluav taws xob, thiab lwm yam., rau kev tswj thiab tiv thaiv kev nyab xeeb ntawm kev ua haujlwm ntawm Circuit Court.
2. Cov khoom siv hauv tsev:
Lub tshuab nqus tsev tsis tshua muaj hluav taws xob cuam tshuam kuj tseem siv rau hauv cov khoom siv hauv tsev. Piv txwv li, nyob rau hauv Circuit Court tswj system ntawm tub yees, tshuab ntxhua khaub ncaws, cua txias thiab lwm yam khoom siv hauv tsev, nws yog tsuas yog siv rau Circuit Court tawg thiab tiv thaiv kev ua haujlwm.
3. Muaj automation:
Nyob rau hauv kev lag luam automation, low-voltage nqus interrupters yog siv nyob rau hauv ntau yam automation khoom thiab tswj systems. Lawv tuaj yeem ua kom ruaj khov ntawm cov khoom siv automation.
4. Cov khoom siv sib txuas lus thiab tshaj tawm:
Kev sib txuas lus thiab cov khoom siv tshaj tawm yuav tsum muaj kev ruaj ntseg thiab kev ntseeg siab ntawm Circuit Court, thiab cov khoom siv hluav taws xob tsawg tsawg tuaj yeem ua tau raws li cov cai no.
5. Lwm qhov chaw:
Tsawg-voltage nqus interrupters kuj siv nyob rau hauv mining, roj av, tshuaj thiab lwm yam kev lag luam teb nyob rau hauv lub hwj chim faib system, raws li zoo raws li lub zog tshiab lub zog tsim system nyob rau hauv lub Circuit Court system.
