SMART SHEATH FOR ELECTRIC CABLES, ELECTRICAL EQUIPMENT POWERED BY THE CABLE AND SYSTEM COMPRISING THE EQUIPMENT

摘要

A smart sheath for the protection of an electric cable comprises an inner insulating tubular layer (3) adapted to contain the conductive elements (4) of the electric cable (1), an outer tubular protective layer (5) placed on the inner tubular layer (3), coaxially thereto, an electric control circuit (6) arranged inside the outer tubular layer (5) and adapted to intercept the induced electric currents generated by the passage of the electric current in the conductive elements (4). Furthermore, the electric control circuit (6) is operatively connected to electric current sensor means (7) and to microcontrollers (13) adapted to discriminate a value of the induced electric current higher than a predetermined maximum value to signal an overload inside the electric cable (1) or absence of the induced electric current for report a possible short-circuit.
