Description
In elektrischen Schiebewiderständen wird beim Gebrauch Wärme erzeugt, die sich unangenehm auf den Schieber auswiYkt, der gewöhnlich von Hand betätigt wird. Bei Überlastungen des Widerstandes kann die Erwärmung des Schiebers eine Höhe erreichen, daß er kaum noch angefaßt werden kann. Besonders ist dies der Fall, wenn der Widerstand in liegender Anordnung gebraucht wird und der Schieber sich oberhalb des Widerstandsträgers befindet.In electrical slide resistors, heat is generated during use, which has an unpleasant effect on the slide, which is usually operated by hand will. If the resistance is overloaded, the slide valve can become very hot achieve that it can hardly be touched. This is especially the case when the resistor is used in a lying position and the slide is above it of the resistor carrier is located.
Um eine bei Benutzung des Widerstandes störende Erwärmung des Schiebers zu verhüten, ist erfindungsgemäß zwischen dem Handgriff des Schiebekontaktes und der Widerstandswicklung ein Strahlungsschutz aus Wärmestrahlen reflektierendem, hitzebeständigem Werkstoff angeordnet.To prevent the slide from heating up when the resistor is used to prevent is according to the invention between the handle of the sliding contact and the resistance winding a radiation protection made of heat rays reflecting, heat-resistant material arranged.
An dem in Abb. i dargestellten Schieber ist unterhalb des auf einer Schieberstange a gleitenden Schieberkastens b ein Strahlungsschutz c angebracht, der aus einem Wärmestrahlen reflektierenden, hitzebeständigen Werkstoff, beispielsweise Aluminiumblech, besteht. Dieser Wärmeschutz c, der in Abb.2 seitlich und in Abb. 3 von oben gesehen dargestellt ist, ist so breit, daß er den ganzen Schieberkasten b mit dem Griff d aus keramischer :Masse sowie den Kontaktfedern e und der Druckfeder f vor strahlender Wärme schützt. Die Strömungspfeile in Abb. 2 deuten an, wie etwa die heiße Luft auf dem Wege vom Widerstandsleiter zum Schieber abgeleitet wird.On the slide shown in Fig. I is below the on one Valve rod a sliding valve body b a radiation protection c attached, the heat-resistant material reflecting heat rays, for example Aluminum sheet. This thermal insulation c, which is shown on the side in Fig. 2 and in Fig. 3 is shown seen from above, is so wide that it covers the entire valve body b with the handle d made of ceramic: compound as well as the contact springs e and the compression spring f protects against radiant heat. The flow arrows in Fig. 2 indicate how about the hot air is diverted on the way from the resistance conductor to the slider.
In der seitlichen Länge ist der Wärmeschutz c so weit geführt, daß er etwas über die Kontaktfedern e noch hinausragt und diese in einer kleinen Aussparung g aufnimmt. Hierdurch wird eine seitliche Verdrehung der Kontaktfeder e beim Gleiten über die Widerstandswicklung h verhindert.In the lateral length of the thermal protection c is so far that it protrudes a little over the contact springs e and these in a small recess g takes up. This causes a lateral rotation of the contact spring e when sliding prevented via the resistance winding h.
Durch den Einbau des Wärmeschutzes ist eine größere Betriebssicherheit des Schiebewiderstandes und ein besseres Arbeiten mit demselben erreicht.The installation of the thermal protection means greater operational reliability the sliding resistance and a better working with the same achieved.
