Abstract
Vorrichtung zur Überwachung von physikalischen Größen an einer Strömungsmaschine wie z.B. einer Wasserturbine oder einer Pumpturbine, mit wenigstens drei Überwachungskanälen, einem Arbeitsanschluss, einem Druckanschluss, einem Tankanschluss und wenigstens drei gleichen Ventilen, die zu einer mehrheitsbestimmten Schaltlogik zusammengeschaltet sind, wobei in keinem Betriebszustand der Druckanschluss in leitender Verbindung mit dem Tankanschluss steht.Device for monitoring physical quantities on a turbomachine such as a water turbine or a pump turbine, with at least three monitoring channels, a working connection, a pressure connection, a tank connection and at least three identical valves, which are interconnected to form a majority-determined switching logic, the pressure connection not being in conductive connection with the tank connection in any operating state.
Description
Die Erfindung betrifft eine Vorrichtung zur Überwachung von physikalischen Größen an einer Strömungsmaschine wie z.B. einer Wasserturbine oder einer Pumpturbine.The invention relates to an apparatus for monitoring physical quantities on a turbomachine, e.g. a water turbine or a pump turbine.
Vorrichtungen zu Überwachung von physikalischen Größen an einer Strömungsmaschine sind aus dem allgemeinen Stand der Technik bekannt. So beschreibt beispielsweise die
Als Nachteil des beschriebenen Stands der Technik ergibt sich, dass bei Auslösung die Fördermenge der Druckquelle in den Ablauf abfließt (siehe
Der Erfinder hat sich die Aufgabe gestellt, die beschriebenen Nachteile des Standes der Technik deutlich zu verringern. The inventor has set himself the task to significantly reduce the disadvantages of the prior art described.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung zur Überwachung von physikalischen Größen an einer Strömungsmaschine mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung ergeben sich aus den hiervon abhängigen Unteransprüchen.This object is achieved by a device for monitoring physical quantities on a turbomachine with the characterizing features of claim 1. Further advantageous embodiments of the device according to the invention will become apparent from the dependent therefrom dependent claims.
Der Erfinder hat erkannt, dass sich diese Aufgabe dadurch lösen lässt, dass in keinem Betriebszustand der Druckanschluss in leitender Verbindung mit dem Tankanschluss steht. Besonders vorteilhaft, da kostengünstig, lässt sich diese Anordnung realisieren, wenn drei 8/2-Wegeventile entsprechend verschaltet werden.The inventor has recognized that this object can be achieved by the fact that in no operating state, the pressure port is in a conductive connection with the tank connection. Particularly advantageous, since cost, this arrangement can be realized when three 8/2-way valves are connected accordingly.
Die erfindungsgemäße Lösung wird nachfolgend anhand von Figuren erläutert. Darin ist im Einzelnen folgendes dargestellt:The solution according to the invention is explained below with reference to figures. The following is shown in detail:
