PVCB Auto-Reclosing
General
L & R tsim nws tus kheej lub hom phiaj ncej txuas lub tshuab nqus tsev hloov pauv nrog cov haujlwm sib txawv, txhawm rau ua kom tiav cov neeg siv khoom sib txawv.
Lub tshuab nqus tsev hloov pauv tau tsim los ntawm PVCB hom qub hloov.
Nws nrhiav kev ntseeg siab, yooj yim los tswj cov tswv yim tsim los tsim ib tiam ntawm cov khoom lag luam zoo tshaj, yog kev ntseeg siab tshaj plaws kev siv hluav taws xob zoo tshaj plaws.
Ntau hom kev nthuav dav hloov pauv yog xaiv tau los ntawm cov neeg siv khoom xav tau.
L & R txhua qhov hloov pauv ua tau raws li cov hauv qab no: ANSI/IEEE C37.60/EC 62271-100 (GB1984-2003 Tuam Tshoj tus qauv) GBT1 1022-1999 Tuam Tshoj Txuj Ci, IEC 60255-11, IEC 60255-21-1 Hoob I, IEC 60255 -21-2 Hoob I, IEC 60255-21-3 Hoob I, IEC 60255-22-1 Hoob III, IEC 60255-22-2 Hoob IV, IEC 60255-22-3 Hoob III, IEC 60255-22-4 Hoob IV
