Abstract

1. Circuit for the monitoring of a high-voltage fuse with the aid of pulse converters, galvanic separations and pulse/direct-current converters as well as a logic, characterized in that the applied high voltage (1, 3) can be fed via a series resistor (8) and the voltage (1, 2) applied over the fuse (F) to be monitored can be fed via a further series resistor (5) in each case to a pulse converter (9, 6), the pulses can be fed with galvanic separation (10, 7) in each case to a pulse/direct-current converter (12, 11) and from the latter to a logic (13), which drives a bistable relay (14), which flips into the one position, corresponding to a fuse defect, when a voltage occurs over the fuse (F), triggering an alarm and/or an indication, and only flips into the other position, corresponding to operational readiness, when the voltage (1, 2) occurring over the fuse (F) disappears and at the same time the high voltage (1, 3) is applied.
