Abstract
Die Erfindung betrifft eine elektrische Schaltung (9) zur Versorgung einer Kraftstoffzusatzheizung (10) mit wenigstens einer laststromführenden Verbindung (11) von einem Anschlussstecker (12) zu einer Steuerung (14) und wenigstens einer weiteren laststromführenden Verbindung (13) zu der Kraftstoffzusatzheizung (10). Die elektrische Schaltung ist dadurch gekennzeichnet, dass der Stromdurchfluss durch die laststromführenden Verbindungen (11, 13) überwacht wird.The invention relates to an electrical circuit (9) for supplying a fuel additive heater (10) with at least one load current carrying connection (11) from a connection plug (12) to a controller (14) and at least one further load current carrying connection (13) to the auxiliary fuel heater (10 ). The electrical circuit is characterized in that the current flow through the load current carrying connections (11, 13) is monitored.
Description
Die Erfindung betrifft eine elektrische Schaltung zur Versorgung einer Kraftstoffzusatzheizung mit wenigstens einer laststromführenden Verbindung von einem Anschlussstecker zu einer Steuerung und wenigstens einer weiteren laststromführenden Verbindung zu der Kraftstoffzusatzheizung.The The invention relates to an electrical circuit for supplying a Fuel additive heating with at least one load current-carrying Connection from a connector to a controller and at least another load-carrying connection to the additional fuel heater.
Aus
der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Schaltung zu entwickeln, die eine hohe Funktionssicherheit hat und die durch Überwachung wirksam gegen Überhitzung geschützt ist.Of the Invention is therefore based on the object to develop a circuit which has a high reliability and effective by monitoring is protected against overheating.
Diese Aufgabe wird durch eine Schaltung nach Anspruch 1 gelöst.These The object is achieved by a circuit according to claim 1.
Dadurch, dass der Stromdurchfluss durch die laststromführenden Verbindungen im gesamten Laststrompfad vergleichend überwacht wird, kann eine Zerstörung der Schaltung durch Überhitzung sicher verhindert werden. Zusätzlich können noch zwei in Reihe geschaltete redundante Schalter die Sicherheit der Schaltung weiter erhöhen.Thereby, that the current flow through the load current carrying connections monitored comparatively throughout the load current path, can damage the circuit due to overheating safely prevented. In addition, still can two series connected redundant switches ensure the safety of the Increase the circuit further.
