Description
"Heizkabel mit Schutzleiter" Bei der Verlegung und Verwendung von Heizkabeln ist in vielen Fällen die Notwendigkeit und Vorschrift gegeben, das Heizkabel zusätzlich mit einer Schutzmaßnahme zu versehen, um Fehlerströme sofort zu er-. fassen und schädliche Auswirkungen zu verhindern. Dies ist besonders notwendig bei Bodenheizungen und bei Beheizungen von*Anlagen und Geräten, die unter entsprechende Schutzbestimmungen fallen: Mit normalen Heizkabeln, die nur einen Heizleiter besitzen und den üblichen Mantelaufbau, ist die Durchführung einer solchen Schutzmaßnahme nicht möglich."Heating cable with protective conductor" When laying and using In many cases, heating cables are required and prescribed, the heating cable additionally to be provided with a protective measure in order to immediately detect fault currents. grasp and prevent harmful effects. This is especially necessary with Floor heating and for heating * systems and devices, which are under appropriate Protective regulations fall: With normal heating cables that only have one heating conductor and the usual jacket structure, is the implementation of such a protective measure not possible.
Die Erfindung erstreckt sieh darauf, daß bei einem normalen Heizkabel ('f) zusätzlich zwischen zwei. Isolationsmänteln (3) eine leitende Ummantelung (2) in Form einer Umspinnung o.ä. aufgebracht wird, die durch Anschluß an ein entsprechendes Überwachunge- oder /Kontrollgerät (5) dazu dient, irgendwelche Beschädigungen an dem Kabel zu erfassen, bevor der Heizleiter (4) beschädigt wird und -Überströme oder Fehlerspannungen auftreten können.The invention extends to a normal heating cable ('f) additionally between two. Insulation jackets (3) a conductive sheath (2) is applied in the form of a wrapping or the like, which is connected to a corresponding Monitoring or / control device (5) serves to indicate any damage the cable before the heating conductor (4) is damaged and overcurrents or fault voltages can occur.
Gleichzeitig dient diese Einrichtung dazu, Übertemperaturen am Heiz-Leiter (4) auszuschalten bzw. zu begrenzen.At the same time, this device serves to prevent excess temperatures on the heating conductor (4) switch off or limit.
Erfindungsgemäß kann mit dieser Einrichtung an dem-aufgebrachten Schutzleiter ein Kontrollgerät (5) angeschlossen werden, das so aufgebaut ist, daß es den entsprechenden Schutzbestimmungen entspricht und eine Installation von Heizkabeln auch in explosionsgefährdeten Anlagen ermöglicht.According to the invention, this device can be used on the protective conductor a control device (5) can be connected, which is constructed so that it is the corresponding Protection regulations and an installation of heating cables also in potentially explosive areas Facilities.
