    摘要: A multi-step tube (1) of a ceramic material comprises a tube body (1) of the ceramic material having an inner wall (11) located inside the tube body (1). A surface of the inner wall (11) is formed with a plurality of steps (2). The steps (2) are formed to extend differently far inside the tube (1). A multi-layered gas discharge tube comprises the multi-step tube (1). An inner electrode (31) is disposed on a step (21), and an outer electrode (41) is disposed on an outer surface (13) of the tube body (1). A disc (51) is partially placed on a step (22) and the inner electrode (31) between the inner electrode (31) and the outer electrode (41) so that, in case of an electrostatic discharge, the discharge will only take place in the center of the multi-step tube (1) and not at the border of the isolated ceramic disc (51).

    摘要: A station arrester employing metal oxide varistors has varistors whose capacitances increase in a direction measured from the ground side of the arrester. An approximately uniform voltage distribution can be produced across the varistors when appropriately graded according to their positions in the varistor stack. In this configuration, the varistor disks located near the top or line end of the stack are not subjected to increased thermal stresses.

    摘要: A surge diverter connected between a conductor and ground comprising several spark-quenching gaps, voltage-controlled shunting resistors connected in series with these gaps and voltage controlled control-resistors, each connected in parallel either to a gap alone or to a unit formed by a gap and a shunting resistor in series with the latter. The voltage-controlled control-resistors have current-voltage characteristics with substantially the same steepness, while the resistance value of these control-resistors at the rated voltage increases sequentially from the conductor to grand.

    摘要: A surge diverter is mounted in an inner casing of electrically insulating material which is enclosed in an outer housing of electrically conducting material which is connected to earth. In the space between the inner casing and the housing a number of grading rings in the form of toroid rings are fastened to the inner casing at a distance from it. The grading rings are arranged at a distance from each other which increases counting from the top of the diverter.

    摘要: A SURGE VOLTAGE ARRESTER, SUCH AS A LIGHTNING ARRESTER, IS PROVIDED WITH A SPRING-LOADED MOUNTING MEANS FOR RELEASABLY SUPPORTING A PLURALITY OF CAPACITORS IN A SERIES CIRCUIT ARRANGEMENT IN WHICH THEY ACT AS A VOLTAGE GRADING CIRCUIT FOR THE SPARKGAP ASSEMBLIES OF THE ARRESTER. THE MOUNTING MEANS INCLUDES A PLURALITY OF SLIDABLY ENGAGEABLE TERMINAL AND CONTACT MEMBERS THAT ARE SHAPED TO COOPERATE WITH RECESSED TERMINALS IN THE GRADING CAPACITORS TO FORM A RELATIVELY RIGID MOUNTING COLUMN THAT IS EFFECTIVE TO SUPPORT THE CAPACITORS IN A PREDETERMINED POSITION ADJACENT THE SPARKGAP ASSEMBLIES OF THE ARRESTER. THE MOUNTING MEANS ARE FURTHER OPERABLE TO PERMIT RE-

    MOVAL OF ONE OR MORE OF THE CAPACITORS FROM THE SERIESCONNECTED COLUMN WITHOUT REQUIRING DISASSEMBLY OF THE ENTIRE COLUMN.
