Lub NT2 fuse ua haujlwm zoo li 'airbag' rau lub tshuab hluav taws xob. Thaum qhov txawv txav tam sim no nce, nws cov hlau tshwj xeeb sab hauv melts sai sai thiab txiav tawm hauv Circuit Court. Nws cov haujlwm tseem ceeb yog peb npaug:
- Kev tiv thaiv overload: ncua kev ua haujlwm nyob rau hauv tas li overload
- Kev tiv thaiv luv luv: Teb tsis pub dhau 0.1 vib nas this kom nrawm nrawm tam sim no
- Fault isolation: Tsim kom muaj qhov sib cais meej meej tom qab melting
Qhov fuse no yog tsim los nrog cov kev xav tau ntawm kev lag luam hauv siab:
- Rated voltage npog 380V, rwb thaiv tsev lub zog raws li cov qauv
- Kev tawg muaj peev xwm ncav cuag 10kA, muaj peev xwm tuav kev lag luam luv luv - cuam tshuam rau hauv Circuit Court
- Nco tseg: Peb -phase balanced configuration yuav tsum tau; ywj siab installation ntawm txhua theem yog pom zoo.
- Derating yog tsim nyog nyob rau hauv siab -kub ib puag ncig; pom zoo 20% margin.
