    Elektrischer   Rohrheizkörper für Hochspannung. 



   Für Niederspannung werden Rohrheizkörper verwendet, welche in zylindrischen Nutenkörpern aus Isoliermaterial eingezogene Heizwendeln besitzen. Die   Trennungsstege   zwischen den einzelnen
Nuten dienen zur   Distanzierung   des Heizkörpers vom   metallischen   Rohrgehäuse. 



   Für Hochspannung müssten zwecks   Vergrösserung   der Kriechstreeke, so wie in Fig. 1 dargestellt, die Stege a'der Isolierkörper   radial verlängert werden, wodurch die Festigkeit ungenügend wird. 



   Falls jedoch die Stege kräftig ausgeführt werden, ist die   Raumausnutzung zwecks Unterbringung   
 EMI1.1 
 Halteseele c bezeichnet, welche für den   mechanischen     Zusammenhalt   der gewöhnlich kurzen, aneinandergereihten Nutenkörper dient, gibt für Hochspannung zu kleine   Kriech- und tberschlagswege.   



   Gegenstand der Erfindung ist ein elektrischer   Rohrheizkörper gemäss Fig. 2,   dessen Nutenkörper   11,   
 EMI1.2 
 Spannung, die Nutenstege nur für die jeweilige Nutenspannung bemessen. 



   Die Halteseelen g sind an den Umfang der Distanzstege e verlegt. 



   Um ein direktes Anliegen der Nutenkörper an der Innenwand des Rohrgehäuses f zu verhindern, ragen die Halteseelen   g   über den   Umfang   der Distanzstege p hinaus. 



   Die beiden Enden der äussersten aneinandergereihten Nutenkörper werden, wie   Fig. a zeigt,   mittels isolierender   Abschlussplatte   h abgeschlossen. An der   Anschlussseite   sind die   Anschlusslitzen   durch Löcher i zu den Klemmen k geführt. 



   Um die   Wärmeübertragung   vom Heizkörper auf die Klemmen möglichst zu verhindern, können nach den Nutenkörpern wärmeisolierende Hohlkörper h mit Hohlräumen l angeordnet sein.

    Electric tubular heater for high voltage.



   For low voltage, tubular heating elements are used, which have heating coils drawn into cylindrical groove bodies made of insulating material. The dividers between each
Grooves are used to distance the radiator from the metallic tubular housing.



   For high voltage, in order to enlarge the creepage distance, as shown in FIG. 1, the webs a 'of the insulating bodies would have to be lengthened radially, as a result of which the strength would be insufficient.



   However, if the webs are made strong, the space is used for the purpose of accommodation
 EMI1.1
 Retaining core c denotes, which is used for the mechanical cohesion of the usually short, lined up groove bodies, and creep and flashover paths that are too small for high voltage.



   The invention relates to an electric tubular heater according to FIG. 2, the groove body 11 of which
 EMI1.2
 Tension, the slot webs only dimensioned for the respective slot tension.



   The retaining souls g are laid on the circumference of the spacer bars e.



   In order to prevent the groove body from resting directly on the inner wall of the tubular housing f, the retaining elements g protrude beyond the circumference of the spacer webs p.



   The two ends of the outermost juxtaposed groove bodies are, as FIG. A shows, closed by means of an insulating end plate h. On the connection side, the connection strands are led through holes i to the terminals k.



   In order to prevent the heat transfer from the radiator to the clamps as much as possible, heat-insulating hollow bodies h with cavities l can be arranged after the groove bodies.



   PATENT CLAIMS:
1. Electric tubular heater for high voltage, characterized in that the iso-
 EMI1.3
 have specially designed spacer bars (e) for full tension.
