摘要： The present invention provides a space-saving and low-cost emergency power system, which can be installed on a narrow place having limited space and employs a battery that is long in service life and low in frequency of replacement. This emergency power system comprises a circuit having a DC load, a rectifier, and a battery, which are electrically connected to one another. This circuit is adapted so that normally, DC power is supplied from the rectifier to the DC load, and the battery is charged, and that in an emergency, such as a power failure, in which an outage of the rectifier occurs, electric power is automatically supplied from the battery to the DC load. In this system, a sodium sulfur battery is employed as the battery.

摘要： PURPOSE: To provide a setting method of a clearance between a solid electrolyte tube and a separator in a sodium-sulfur battery by which a minute clearance between the solid electrolyte tube and the separator can be easily and accurately set in spite of dispersion of an inside diameter of the solid electrolyte tube. CONSTITUTION: An outside diameter of a 8 after being plastically deformed at a room temperature is found from a clearance (g1 ) being a target at an operating temperature of a battery. On the other hand, the relationship between pressure applied to the inside of the separator 8 and the outside diameter of the separator 8 plastically deformed by its pressure is previously found. Water pressure applied to the inside of the separator 8 is found from the outside diameter of the separator 8 after being plastically deformed at the room temperature on the basis of the relationship. Afterwards, the separator 8 is arranged in a solid electrolyte tube 4, and the separator 8 is plastically deformed by pressurizing it by prescribed water pressure from inside of the separator 8. Next, the water pressure is released, and a clearance (g0 ) between the solid electrolyte tube 4 and the separator 8 is set in a prescribed value.

A controller, which issues commands for charging and discharging to the power storage system 5 and a switch 6, are electrically connected with the system. During normal operation, power is supplied from the power system 1 to the power load facility 2, and further the high-temperature secondary battery 3 is charged. If instantaneous power interruption or power failure occurs in the power system 1, power is supplied from the secondary battery to the power load facility 2. When the high-temperature secondary battery 3 supplies power to the power load facility 2, at at least one unit cell in at least one of modular batteries 9, the temperature in the electric cell while outputting power is measured directly. When the temperature in the electric cell reaches an allowable limit temperature, power supply to the power load facility 2 is stopped.
