摘要： In an enclosed-type zinc-oxide surge arrester with a grounded tank filled with an insulating medium, and a non-linear resistor assemblage which is connected at one end to a high voltage conductor and at the other end to the ground potential portion within the grounded tank, two or more ring-like shield means such as shield rings are disposed on the high voltage conductor side of the non-linear resistor assemblage at given distances. The use of the ring-like shield means makes more uniform the voltages shared by the respective non-linear resistors. The ring-like shield means may be formed with the configuration and diameter, and the number of them used being properly selected.

摘要： Disclosed is a lightning arrester provided for a power transmission line so as to prevent damage to a line-supporting insulator string due to lightning stroke. A lightning arrester unit is fixedly supported on a fitting fixed to an arm structure of a tower in a relation in which its grounded side is electrically insulated from the fitting, and an operation detection device is connected between the grounded side of the lightning arrester unit and the fitting. The operation detection device is in the form of an operation indicator, a flashover indicator and/or an operation recorder. In the event of impartation of a lightning stroke, the operation detection device detects lightning current flowing from the grounded side of the lightning arrester unit toward the fitting.

摘要： A grounding tank type arrester comprises a plurality of columns sorted into current folding columns and current pass columns. Each current folding column includes a plurality of stack sets of an element unit, having a plurality of zinc oxide elements, and an insulating spacer and the plural stack sets are stacked in regular sequence so that one element unit and one insulating spacer are stacked alternately. Each current pass column includes a plurality of stack sets of a zinc oxide element and an insulating spacer and the plural stack sets are stacked in regular sequence so that one zinc oxide element and one insulating spacer are stacked alternately. Individual zinc oxide elements on one level of individual current folding columns and individual zinc oxide elements on the one level of individual current pass columns are interconnected together by bridge conductor plates. The direction of current flowing through bridge conductor plates for connecting together zinc oxide elements on the one level of the current folding columns and current pass columns is inverse to the direction of current flowing through bridge conductor plates for connecting together zinc oxide elements on the neighboring level of the current folding columns and current pass columns and hence the residual inductance of the arrester can be reduced.
