The primary side of step-down transformer 106 is connected with the normally closed contact of the first relay 105, thus under cable power supply normal condition, primary side all the time electric.
The input end of the second relay 107 is connected with the secondary side of step-down transformer 106, and thus, under cable power supply normal condition, the second relay 107 coil obtains electric, and normally opened contact hold mode, alarm module dead electricity, does not send alerting signal.
The feeder ear of alarm module is connected with the normally opened contact of the second relay 107, and what control alarm module supplies power-off.
Wherein, the second relay 107 adopts internal battery powers, is controlled the break-make of supply line by the normally opened contact of the second relay 107; When cable fault, the normally closed contact of the first relay 105 disconnects, and the secondary side decompression of step-down transformer 106, causes the second relay 107 decompression action, and closed normally opened contact, conducting alarm module feed circuit, realize actuation of an alarm.
Alarm module comprises: audible-visual annunciator 110, rechargeable battery 109 and charging circuit 108.
Audible-visual annunciator 110 is connected with rechargeable battery 109, and when normally opened contact closes, conducting alarm supply access, performs actuation of an alarm.
Rechargeable battery 109, as internal cell, provides power supply to audible-visual annunciator 110;
