Description

Selbsttätige Ladevorrichtung für elektrische Sammler in Stromversorgungsanlagen mit stark wechselnder Belastung Die selbsttätige Ladevorrichtung für elektrische Sammler nach Patent 666 551 besteht aus einem zum Ladegleichrichter parallel geschalteten Steuergleichrichter, der in Abhängigkeit von seinem Gleichstrom über ein Relais den Ladegleichrichter je nach dem Ladezustand des Sammlers ein- und abschaltet.Automatic charging device for electrical collectors in power supply systems with strongly changing loads The automatic charging device for electrical The collector according to patent 666 551 consists of a charging rectifier connected in parallel Control rectifier, which is dependent on its direct current via a relay switches the charging rectifier on and off depending on the charge level of the collector.

Bei einer nach dieser Schaltung arbeitenden Anordnung kann es bei einem bestimmten Grenzwert vorkommen, daß das Relais mehrfach ein- und ausschaltet, bis dieser kritische Punkt des Spannungszustandes der Batterie überwunden ist. Obwohl dieser Fall nur beim Zusammentreffen verschiedener Umstände zu erwarten ist, ist es doch ratsam, eine auch in dieser Beziehung sicher arbeitende selbsttätige Ladevorrichtung zu schaffen.In an arrangement operating according to this circuit, it can be at a certain limit value that the relay switches on and off several times, until this critical point in the voltage condition of the battery has been overcome. Even though this case is only to be expected when different circumstances coincide it is advisable to have an automatic charging device that works safely in this respect too to accomplish.

Da beim Einschalten des Ladegleichrichters die Batteriespannung dann sofort ansteigt, wenn der Ladestrom im Verhältnis zur Kapazität der Batterie groß ist, während augenblicklich kein Verbraucherstrom vorhanden und vielleicht auch noch durch ungenügende Ouerschnittsbemessung der Netzleitung ein Spannungsabfall auftritt, sinkt im Augenblick der Anschaltung der Steuerstrom des kleinen Steuergleichrichters unter Umständen um einen Wert, der eine sofortige Wiederabschaltung des Ladegleichrichters bewirkt. Man kann zwar das zur Steuerung dienende Relais so ausbilden, daß zwischen Einschalt- und Haltestrom eine verhältnismäßig große Differenz besteht, so daß auch bei einem starken Absinken des im Augenblick der Einschaltung vorhandenen Steuerstromes eine Wiederabschaltung des Ladegleichrichters durch das Relais noch nicht erfolgt; jedoch wird auch diese Maßnahme dann nicht zu einem Erfolg führen, wenn die oben angeführten Umstände, die zur Verringerung der dem Steuergleichrichter zugeführten Wechselspannung führen, besonders stark auftreten.Since when switching on the charging rectifier the battery voltage then increases immediately when the charging current is large in relation to the capacity of the battery is while there is currently no consumer power and maybe also nor a voltage drop due to insufficient cross-section dimensioning of the power line occurs, the control current of the small control rectifier drops at the moment of connection possibly by a value that immediately switches off the charging rectifier again causes. You can do that for control train serving relays in such a way, that there is a relatively large difference between the inrush and holding currents, so that even in the event of a sharp drop in what is present at the moment of switching on Control current a switch-off of the charging rectifier by the relay still not happened; however, this measure will not lead to success either, if the above circumstances that reduce the control rectifier lead supplied AC voltage, occur particularly strong.

Zur Vermeidung dieses unerwünschten Zu-und Abschaltens des Ladegleichrichters wird erfindungsgemäß, wie die Abbildung zeigt, die Primärwicklung des zu dem Ladegleichrichter G gehörigen Transformators T in Reihe mit einigen Primärwindungen oder zusätzlichen Wicklungen des Steuergleichrichtertransformators T' geschaltet. Hierdurch wird erreicht, daß beim Einschalten des Ladegleichrichters G in den Windungen der Sekundärwicklung des Transformators T', also am Steuergleichrichter g, die Wechselspannung erhöht wird und der Steuerstrom zunimmt, so daß im Augenblick der Einschaltung des Ladegleichrichters das Relais r seine Haltekraft vergrößert. Durch diese Anordnung hat man es in der Hand, die Differenz zwischen der Ein- und Abschaltstromstärke des Relais zu verändern und damit auch die Betriebssicherheit der Anordnung zu erhöhen. Es ist dabei gleichgültig, für welche Zellenspannung die Anschaltung des Ladegleichrichters eingestellt wird und kann auch diese Veränderung erfolgen, ohne daß die Betriebssicherheit der Anordnung geringer wird.To avoid this undesired switching on and off of the charging rectifier According to the invention, as the figure shows, the primary winding of the to the charging rectifier G belonging transformer T in series with some primary turns or additional Windings of the control rectifier transformer T 'switched. This achieves that when you turn on the charging rectifier G in the turns of the secondary winding of the transformer T ', that is to say at the control rectifier g, the AC voltage is increased and the control current increases so that at the moment the charging rectifier is switched on the relay r increases its holding force. With this arrangement you have it in the Hand to change the difference between the switch-on and switch-off currents of the relay and thus also to increase the operational reliability of the arrangement. It doesn't matter for which cell voltage the connection of the charging rectifier is set and this change can also take place without affecting the operational reliability of the arrangement becomes less.
