Abstract (en)
[origin: WO8102812A1] In an overvoltage shunting device enclosed in an electrically conductive, earthed housing (1), and comprising shunting elements (2) in the shape of stacked discs in at least one column and a protection and control body in order to obtain a linear distribution of the potential along the active part (3), it is possible to obtain with the aid of simple means, also in overvoltage shunting devices produced in small series, a good distribution of the electrical field. For this purpose, the protection and control body is composed of two electrically conductive layers (6) surrounding approximatively concentrically the active part (3) of the device, each one being electrically insulated from the others and wrapped in a body (5) of an insulating material. These layers are disposed parallel to the axis of the column of the active part (3) and shifted from one another at their opposite ends on the high voltage conductive side of the active part (3), so as to form a stair way on their internal side facing the active part (3). In such an overvoltage shunting device the linearisation of the voltage drop along the active part (3) is simply obtained and thus the device is not only characterized by its low production cost but also by its extreme compactness. To this must be added the possibility of partially resorting, for the production of such a device, to the technologies used for producing capacitor crossings.
