Abstract

An electric lead with indicator has the electric conductor provided with a twin-coated insulation whose inner layer (indicator) is designed as being of high resistance and semiconducting. The semiconducting high- resistance layer is designed like a radiation collar.

Description

Elektrische Leitungen bzw. Kabel herkömmlicher Art sind mit einer mehr oder minder aufwendigen Isolierschicht versehen. Störfalle mit ihren oft weitreichenden Folgen treten in der Regel abrupt auf und die Möglichkeiten der Schadensbegrenzung sind daher oft gering.Electrical lines or cables of a conventional type are more or less complex Provide insulating layer. Incidents with their often far-reaching consequences usually occur abruptly and the possibilities of limiting the damage are therefore often limited.

Durch Verwendung von elektrischen Leitungen mit einer Indikatorschicht (Patentanspruch 1) soll die Möglichkeit gegeben werden, durch mechanische Beschädigungen kurzschlußgefährdete Bereiche frühzeitig zu erkennen und entsprechende Vorkehrungen zu treffen.By using electrical lines with an indicator layer (claim 1) the opportunity to be given short-circuit risks due to mechanical damage Identify areas early on and take appropriate precautions.

Vorrangige Einsatzbereiche von Leitungen mit Indikator sollen dynamisch belastete, potential­ führende und brandgefährdete Umgebungen sein (z. B. Flugzeugbau).Priority areas of use for lines with indicators are to be dynamically loaded, potential leading and fire-prone environments (e.g. aircraft construction).

Scheuert sich die Isolierung durch und es entsteht ein elektrischer Kontakt zu einer potential­ führenden Umgebung, führt dies nicht zwangsläufig zu einem Kurzschluß, aufgrund des hohen elektrischen Widerstandes, wohl jedoch zu einer meßtechnisch erfaßbaren Fehlerspannung. Durch Vorschaltung entsprechender Sicherheitseinrichtungen (Fehleranzeige, Abschaltautomatik) können weitergehende Schäden unterdrückt werden.If the insulation rubs through and there is an electrical contact to a potential leading environment, this does not necessarily lead to a short circuit, due to the high electrical resistance, but probably to a measurable error voltage. By connecting appropriate safety devices (error display, automatic switch-off) further damage can be suppressed.

Die strahlenkranzförmige Ausbildung der Indikatorschicht (Patentanspruch 2) soll sicherstellen, daß zunächst nur eine möglichst kleine Stelle mit einem möglichst hohem elektrischen Widerstand Kontakt hat (Zeichnung-Nr. TSC.001).The radiator-shaped design of the indicator layer (claim 2) should ensure that initially only a place as small as possible with a high electrical resistance Has contact (drawing no. TSC.001).

Die Herstellung der zweischichtigen Isolierung kann in einem Arbeitsgang durch 2fach-Extrusion erfolgen. Dieses Verfahren hat sich in der Hochspannungstechnik seit vielen Jahren bewährt.The two-layer insulation can be produced in one step by double extrusion respectively. This process has proven itself in high voltage technology for many years.
