Beschreibung
Zusammenfassung:	The invention belongs to the technical field of power systems, and particularly relates to a low-voltage bypass hot-line work control box. The low-voltage bypass work control box comprises a box body, a disconnecting link and a low-voltage circuit breaker, and is characterized in that the low-voltage bypass work control box further comprises an alarm and three relays. Two coil terminals of the first relay are correspondingly connected with an A1-phase line on the wire inlet side of the disconnecting link and an A2-phase line on the wire outlet side of the disconnecting link respectively, and two coil terminals of the second relay are correspondingly connected with a B1-phase line on the wire inlet side of the disconnecting link and a B2-phase line on the wire outlet side of the disconnecting link respectively. Two coil terminals of the third relay are respectively and correspondingly connected with a C1-phase line at the wire inlet side of the disconnecting link and a C2-phase line at the wire outlet side of
