CONDUCTIVE COMPONENT THAT ATTENUATES VERY FAST OVERVOLTAGES, FOR VERY HIGH-VOLTAGE ELECTRICAL SUBSTATIONS

摘要

The invention relates to a conductive component (21) that attenuates very fast overvoltages, for very high-voltage electrical substations, said component comprising a hollow metal bar (25) a segment (27) of which is machined to form a solenoid. The solenoid segment (27) has an inductance higher than 3 µH. The component furthermore comprises: first and second electrodes (29, 31) that extend radially with respect to the axis (33) of the hollow metal bar (25), said electrodes being connected to the hollow metal bar (25) and defining an internal space (35); and an element (37) that forms both a capacitor and resistor, said element being placed in the internal space (35) and connected to the two electrodes (29, 31).
