    摘要： The invention relates to an isolating switch comprising: a fixed arc contact (20) and a mobile arc contact (22); an isolating nozzle (24) enveloping a part of a first arc contact (20) in such a way that, when the electric arc is formed during a manoeuvre for opening or closing the isolating switch, the isolating nozzle (24) is in contact with the electric arc and undergoes an ablation by the electric arc; and a screen (25) which is mounted on the second arc contact (22), an isolating tip (25b) of the screen (25) being mounted against an end (22a) of the second arc contact (22), which is located on the side of the first arc contact, the isolating tip (25b) being arranged so as to be in contact with the electric arc and to increase the length thereof.

    摘要： The invention relates to a very high voltage DC line voltage sensor, the sensor being made up of a voltage divider comprising two series-connected voltage division stages, a first voltage division stage (E1) being made up of at least two elementary voltage division stages (Em) arranged in series and distributed in a composite insulator (I), each elementary stage (Em) comprising at least one capacitor (Ce) and at least one resistor (Re) in parallel that are fixed to electrically conductive plates (a1, a2), at least one electrically insulating holding piece (S) that encloses the resistor and the capacitor being in contact with the internal wall of the composite insulator (I) in order to fix the capacitor and the resistor to the inside of the composite insulator.
