摘要： A capacitive voltage sensor includes an electrode extending along a longitudinal axis, a tubular portion including a layer of electrically insulating material, a layer of electrically conductive material positioned radially inward of the layer of electrically insulating material in a direction toward the longitudinal axis, and an outer shield configured as a latticelike network and positioned radially outward of the layer of electrically insulating material in a direction away from the longitudinal axis. The layer of electrically conductive material, the layer of electrically insulating material, and the outer shield each surround and is spaced in a direction radially outward from the longitudinal axis and from a portion of the electrode. A mass of dielectric insulating material at least partially encapsulating the electrode and the tubular portion and fills through holes formed in the latticelike network of the outer shield.

摘要： A construction system regarding a capacitive voltage sensor, comprises a source electrode (110/210/310/410), a tubular body (120/220/320/420), and a mass of dielectric insulating material (140/240/340/440). The tubular body (120/220/320/420) comprises: a self-supporting tubular laminar element (123/223/323/423) made of insulating material, in which the self-supporting tubular laminar element (123/223/323/423) is stretched to form the support structure for said tubular body (120/220/320/420); a first thin layer (124/224/324/424) of conductive material applied to the outer surface of said self-supporting tubular laminar element (123/223/323/423), wherein said first thin layer (124/224/324/424) of conductive material is intended to perform the function of an electric screen; a second thin layer (125/225/325/425) of conductive material applied to the inner surface of said self-supporting tubular laminar element (123/223/323/423), wherein said second thin layer (125/225/325/425) of conductive material is designed to form an armature for a capacitive coupling.
