摘要： PURPOSE:To prevent the breakage of a solid electrolyte tube or an insulating plate caused by heat distortion produced by heating a battery by forming the joint flange of a solid electrolyte tube in one body with the solid electrolyte tube with beta-alumina. CONSTITUTION:A cathode container 2 and an anode container 5 are joined to a solid electrolyte tube 4 made of beta-alumina by the joint flange 4a made of beta-alumina which is formed in the upper part of the solid electrolyte tube 4. The maximum thickness of the flange 4a is 1mm or more and is desirable to limit to 0.2 times or more the width of the flange 4a. Where a battery is heated, heat distortion caused by a difference in thermal expansion coefficient between alpha-alumina and beta-alumina and caused by glass joint between the solid electrolyte tube 4 and an insulating plate 3 is eliminated unlike the conventional structure. The number of components and the number of production processes of a sodium-sulfur battery are surely decreased and the production efficiency can be increased.

摘要： PURPOSE:To improve reliability and to enable downsizing by disposing a series circuit of a thyristor with an overvoltage self-protecting function and a resistor in parallel with a smoothing capacitor, and providing a circuit for opening a changeover switch by detecting firing of a VBO free thyristor. CONSTITUTION:If a DC side voltage of an AC/DC converter 3 becomes abnormally high, when a forward voltage between terminals of a VBO free thyristor 5 exceeds an overvoltage self-protecting level, it is fired by an overvoltage. A discharging current of a smoothing capacitor 2 flows from the capacitor 2 through the thyristor 5 and a resistor 6 by firing, the DC voltage of the converter 3 is lowered, and damage due to an overvoltage can be prevented. A current flowing by firing is detected by a current detector 8, and a detection signal is sent to a switch controller 7. The controller 7 opens a changeover switch 4 if the detected current value becomes a predetermined value or more.

摘要： PURPOSE:To improve the reliability of an apparatus by arranging a DC switch between a voltage type self-excited converter and a smoothing capacitor or said smoothing capacitor between the voltage type self-excited converter and DC switch or by using the arrangements at the same time. CONSTITUTION:When a short-circuit or ground fault occurs on the DC side, a short-circuit detector 12 or an earth detector 10 detects the fault so that an OFF signal is given from a gate control circuit 13 to a DC switch and the DC switch 4 is brought to an OFF state to cut OFF an overcurrent flowing through an AC to DC converter 1. In this manner, the overcurrent ceases to flow through the AC to DC converter 1 over a long period of time and the breakdown of the AC to DC converter 1 by the over-current can be prevented beforehand. Also, it is possible to prevent the discharge of the smoothing capacitor 3 so that an apparatus can be restarted even at high speed without recharging the smoothing capacitor.
