摘要： PURPOSE:To execute the location with high accuracy even in a multi-terminal high resistance ground system by collecting current information of a transmission line steel tower side, and estimating a fault point from a current distribution shape. CONSTITUTION:When a system fault is generated between two terminal circuits of a one-end power source 5 and a one-end load 6, a ground current flows to a steel tower 1 corresponding to a fault point and a current effective value distribution becomes a pyramid type having a pyramidic apex centering around its steel tower point. This distribution is detected by a current transformer 7 and a steel tower side terminal equipment 3 at every steel tower 1 and calculated from an effective current value collected by the load 6 through a transmission line 4, and a transmission line fault point of a pyramid type distribution is located with high accuracy even in a multi-terminal high resistance ground system.

摘要： PURPOSE:To provide a sensor for detecting even a trace of sodium or sulfur leaked through a case housing containers containing fused sodium and sulfur individually. CONSTITUTION:At least the detection electrode 2a of a solid electrolytic sensor body 2 composed of a sodium ion conductor (e.g. a composite oxide salt of zirconate-silicate-sodium phosphate(Na1+xZr2SixP3-xO12) is disposed in a case housing containers containing fused sodium and sulfur individually in order to detect a trace of sodium or sulfur leaked from the container by means of a single sensor. A solid electrolytic sensor body is formed of a sodium ion conductor into a sheath and the inner and outer faces thereof are employed, respectively, as a reference electrode and a detection electrode. At least the forward end of the sheath is disposed in the case and a trace of sodium or sulfur leaked through the container is detected by means of a single sensor.

摘要： PURPOSE:To reduce a residual stress for a tension generated at an alpha-alumina member caused by a residual stress by a heat and pressure contact, and prevent generation of cracks in the alpha-alumina member by giving a compression force to a joint part a of the-alumina member with each container of a negative pole and a positive pole. CONSTITUTION:A negative pole container 4 having Na filled inside is provided inside a tube of a solid electrolyte 1. The solid electrolyte 1 is provided in a positive pole container 3 having sulfur filled inside. An alpha-alumina member 2 is installed to the solid electrolyte, and the alpha-alumina member and each container of the negative pole and the positive pole is jointed with each other by a heat and pressure contact with an Al member provided between them. A plate spring 11 for giving a compression force while a battery is operated is provided at a heat and pressure contact jointed part.

摘要： PURPOSE:To make a metallic fiber insertionally arrangeable in a sodium electrode without adding any internal pressure to a solid electrolytic tube as well as to prevent this solid electrolytic tube from being damaged by inserting a mat, where a joint between fibers themselves of the metallic fiber is joined, into the sodium electrode. CONSTITUTION:An interval between a protecting tube 5 and a solid electrolytic tube 2, there is provided with a mat 4 of a metallic fiber with sodium resistance so compactly. This mat 4 has the joining plane made up of having only a joint of respective fibers themselves is crushed at the specified pressure, and by means of the intermetallic diffusion limited to this joint, and it is one that has a hole ratio of 85-98%. This mat comes into contact with the solid electrolytic tube 2 by dint of spring back, and thereby wettability by sodium on a beta-alumina surface is securable. Simultaneously, since the specified hole ratio can be obtained by this mat, any internal pressure is in no case exerted on the solid electrolytic tube 2. With this constitution, damage to the solid electrolytic tube and its extension are preventable.

摘要： PURPOSE:To increase the charge/discharge capacity and to improve the energy efficiency by making such that at least one of the volume resistivity, the surface area per unit volume or the surface polarization resistance factor will have specific characteristic from the cathode section toward the depth direction of the anode section. CONSTITUTION:It is constituted such that the volume resistivity will decrease from the cathode section toward the depth direction of the anode section while the surface area per unit volume will increase and the surface polarization resistance factor will also increase. In order to set the resistivity of porous electron conductive members 4, 5, for example, the quantity of electrochemical reaction at each section of anode is integrated within a charge/discharge range of cell to determine such that the sulfur mol. ratio in sodium polysulfide will be uniform between completion of discharge and stopping time of charge/ discharge. Consequently, the cell reaction in the anode can be uniformed resulting in improvement of the charge/discharge capacity and the energy efficiency.

摘要： PURPOSE:To enable to eliminate non-uniformity in cell reaction caused by the effect of gravity and to prevent the accompanying ineffective use of an active material, by making a porus electrically conductive material to have different electric resistances along the direction of the acceleration of gravity. CONSTITUTION:A positive electrode is made to have different values of electric conductivity at its upper part A and lower part B respectively. That is, the lower part B of the positive electrode includes more molten sulfur than the upper part A of the positive electrode due to the effect of gravity. This is because the molten sulfur fills the voids of the porus electrically conductive material and moves upward because of surface tension. This causes a bias to the branch of current at the onset, resulting lower current density in the upper part of the positive electrode and higher current density in the lower part of the positive electrode. As a result, the difference between x values of the upper and lower parts of the positive electrode approaches zero at the end of discharging, and sodium polysulfide with mole ratio of sulfur to sodium uniform over the entire positive electrode is obtained. In this state, the cell can discharge further and active material can be utilized effectively.

摘要： PURPOSE:To prevent vessel melt-down in case solid electrolyte is damaged, by making a collector electrode of a metal of low melting point which is implanted in implanted in sodium negative electrode. CONSTITUTION:A negative electrode 2 is made of a material of low melting point. Due to the thermal conductivity of sodium, which is a metal, higher enough than that of sulfur, most part of heat generated by sodium-sulfur reaction is transmitted to the sodium side. In case a crack is generated in a solid electrolyte 3, the negative electrode 2 made of a material of low melting point immediately metals to be capable of shutting down the circuit between positive and negative electrodes. The material of the negative electrode 2 is required to have good electric conductivity and good corrosion resistance against sodium, as well as low melting point. Appropriate materials which satisfy these requirements are aluminum which has melting point at about 660 deg.C, aluminum- silicon-magnesium alloy which can have melting point lowered as low as near 600 deg.C, and others.
