Kombinierter analoger primärer Unter- und Überspannungsschutz


Kurzfassung

Mit dieser Innovation ist es möglich, einen primären Netzschutz mit Unterspannungs- und Überspannungsauslösung für vermaschte oder einfache Versorgungsnetze, insbesondere für Spannungsquellen mit reduzierter Überstromfähigkeit ohne zusätzliche Spannungsversorgung zu erzielen.


Hintergrund

This invention comprises an electric power system protection unit with an undervoltage and overcurrent trigger for interconnected or simple power systems with reduced overcurrent capability without the need for an external power supply.

Lösung

The central element of the circuit is a differential amplifier that controls a relay. If the predefined voltage range is left, the current controlling the relay is switched off and the relay contact opens. The relay, which connects the system with the electrical power system, requires only one contact. To increase the reliability it is possible to connect a second relay in series. The device is simple and robust with a calculated MTBF of 300.000 hours.


Vorteile

  • Innovative primary electrical protection without external energy source for mobile or stationary power systems
  • Possibility of defined reclosing (Automation)
  • New protection option for DC networks
  • Simple relay with one N/O contact without additional auxiliary contacts
  • Resistant to vibration and shock
