Description

Sicherheitseinrichtung für eine in den Kondensator einer Dampfkraftanlage eingebaute Reduzierstation Die Erfindung betrifft eine Sicherheitseinrichtung für eine in den Kondensator einer Dampfkraftanlage eingebaute Reduzierstation, in die überschußdampf über Reduzierventile eingeleitet und aus der dieser Dampf - in der Station mittels Einspritzwasser gekühlt - in den Kondensator abgeführt wird und deren Reduzierventile bei unzureichendem Druck des Einspritzkühlwassers geschlossen werden.Safety device for a reducing station built into the condenser of a steam power plant The invention relates to a safety device for a reducing station built into the condenser of a steam power plant, into which excess steam is introduced via reducing valves and from which this steam - cooled in the station by means of injection water - is discharged into the condenser and whose reducing valves are closed when the pressure of the injection cooling water is insufficient.

Daß diese Reduzierstationen nur dann ihre Reduzierventile öffnen können, wenn ein bestimmter Einspritzwasserdruck hinter dem Einspritzwasserventil vorhanden ist, hat den Nachteil, daß überschußdampf, wenn dieser bestimmte Druck des Einspritzwassers noch nicht vorhanden ist, ins Freie geblasen werden muß und dem Kreislauf der Dampfkraftanlage verlorengeht. Diesen Nachteil zu verhindern, bezweckt die Erfindung.That these reducing stations can only open their reducing valves when there is a certain injection water pressure downstream of the injection water valve is, has the disadvantage that excess steam when this certain pressure of the injection water is not yet available, has to be blown outdoors and the circuit of the steam power plant get lost. The invention aims to prevent this disadvantage.

Die Erfindung besteht darin, daß zwischen den Einspritzwasser-Druckfühler und die Reduzierventile ein Zeitrelais geschaltet ist, das den Impuls des Druckfühlers um eine einstellbare Zeit verzögert. Das Zeitrelais selbst kann elektrisch oder pneumatisch oder hydraulisch wirken.The invention consists in that between the injection water pressure sensor and the reducing valve is connected to a timing relay that receives the pulse of the pressure sensor delayed by an adjustable time. The timing relay itself can be electrical or act pneumatically or hydraulically.

Der Vorteil der Erfindung ist darin zu sehen, daß die Reduzierventile unabhängig davon, ob bereits der erforderliche Einspritzwasserdruck vorhanden ist, zu- nächst öffnen. Ist nach der eingestellten Zeit der Einspritzwasserdruck noch nicht auf die erforderliche Höhe angestiegen, dann wird der Impuls des Druckfühlers auf die Steuerung der Reduzierventile voll wirksam, so daß diese Ventile geschlossen werden. Dadurch wird verhindert, daß ungekühlter Heißdampf längere Zeit in den Kondensator eingespeist wird.The advantage of the invention is the fact that the reducing valves regardless of whether already the required injection water pressure is available, initially open. If the injection water pressure has not yet risen to the required level after the set time, the pulse from the pressure sensor is fully effective on the control of the reducing valves, so that these valves are closed. This prevents uncooled superheated steam from being fed into the condenser for a longer period of time.

In der Zeichnung ist schematisch ein Ausführungsbeispiel nach der Erfindung wiedergegeben.In the drawing, an embodiment is schematically shown in FIG Invention reproduced.

In den Kondensator 16, der als Mischkondensator oder als Oberflächenkondensator ausgebildet sein kann, ist die Reduzierstation 17 eingebaut. Ihr wird der Überschußdampf über die Leitungen 18 und 19 zugeführt; er kann durch die Reduzierventile 11 und 12 abgesperrt werden. Das Kondensat wird aus dem Kondensator in üblicher Weise über die Kondensatpumpe 20 und ein Regelventil 21 dem Speisewasserkreislauf der Dampfkraftanlage zugeführt. Die Steuerung der Reduzierventile wird vom Einspritzwasser-Druckfühler 15 überwacht. Gemäß der Erfindung ist zwischen diesem Druckfühler und der Steuerung der Reduzierventile das Zeitrelais 13 eingeschaltet, das die Impulse des Druckfühlers 15 auf die Reduzierventile verzögert. Zur Betätigung der Reduzierventile sind die Stellmotoren 22 und 23 vorgesehen; diese werden abhängig vom Zeitrelais über einen Magnetschieber betätigt. The reducing station 17 is built into the condenser 16, which can be designed as a mixing condenser or as a surface condenser. The excess steam is fed to it via lines 18 and 19; it can be shut off by the reducing valves 11 and 12. The condensate is fed from the condenser in the usual way via the condensate pump 20 and a control valve 21 to the feed water circuit of the steam power plant. The control of the reducing valves is monitored by the injection water pressure sensor 15. According to the invention, the timing relay 13 is switched on between this pressure sensor and the control of the reducing valves, which delays the pulses from the pressure sensor 15 to the reducing valves. To operate the reducing valves, the servomotors 22 and 23 are provided; these are actuated via a magnetic slide depending on the timing relay.

Der Gegenstand der Erfindung erlangt besondere Bedeutung bei seiner Anwendung für Dampfkraftanlagen, die ihren Dampf aus dem Wärmetauscher eines Reaktors beziehen.The subject matter of the invention acquires particular importance in his Application for steam power plants that get their steam from the heat exchanger of a reactor relate.
