摘要： A transmission line protection system arranged such that a leakage current detector is provided at an end of an insulating device such as an insulator connected at one end to a corresponding one of arms of a steel tower and connected at the other end to a transmission line of each phase, thereby detecting an arrester leakage current flowing in the transmission line of each phase, an output signal of the leakage current detector being led to a repeater through an optical fiber cable, an output of the repeater being transferred to a control/supervisory board in a substation through an optical fiber cable. In the control/supervisory board, preferably, a received digital signal which was converted from an analog signal at said leakage current detector is displayed on a cathode ray tube. In such an arrangement, it is possible to smoothly perform supervision of the status of the transmission lines without causing maloperations due to influences from the transmission lines.

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： In a tablet unit comprising a plurality of X-axis magnetic wires and a plurality of Y-axis magnetic wires arranged on a tablet board in a matrix fashion for detecting an abscissa and an ordinate, respectively, each of the plurality of X-axis and Y-axis magnetic wires is made of an amorphous material. The plurality of X-axis magnetic wires are divided into first through N-th groups. Any one of the X-axis magnetic wires belonging to a particular group is arranged to adjoin two other X-axis magnetic wires belonging to different groups to form a specific combination of three different groups so that those X-axis magnetic wires belonging to the particular group are spaced from one another by at least a predetermined distance and that the specific combination is unique and does not repeatedly appear. The X-axis magnetic wires belonging to each group are connected to one another in series or in parallel. The plurality of Y-axis magnetic wires are utilized in the manner similar to that of the plurality of X-axis magnetic wires. A switching circuit successively and selectively put the plurality of X-axis and Y-axis magnetic wires group by group into the electroconductive state in a predetermined cycle.

摘要： A zinc oxide lightning protector, wherein end plates are mounted at the ends of an insulator and a zinc oxide element section is arranged between the cover plates. Support metal members are mounted on the cover plates between the zinc oxide element section and the insulator to support an insulation cylinder therebetween. A space is formed between at least an end of an insulation cylinder and a corresponding cover plate to absorb the expansion or contraction of the insulation cylinder due to temperature changes, thus preventing the insulation cylinder from deforming. The elements are eccentrically arranged against the insulation cylinder, to thereby cause the gas flow along peripheral direction so that the laminar flow is changed into a turbulent flow. Thus, the heat conduction is improved to improve the radiation characteristic of the zinc oxide element section.
