せるようにする等細部の構成は任意である。In the figure, (1) is a stationary high-temperature battery in which a plurality of sodium-sulfur cells (3) are arranged and stored in a stainless steel container (2). In the embodiment, this stationary high-temperature battery (1 4) are shown in parallel. A heater (4) is installed inside each storage container (2), and a temperature control blower pipe (5a) and a temperature control blower pipe (5b) are connected, and further inside the wall. An insulating material (6) is attached so that an operating temperature of 300 to 350 ° C is always maintained. Further, the storage container (2) has an internal temperature sensor for detecting an internal operating temperature, a generated gas, a current value, and a voltage as an abnormality detection device for discriminating an abnormality occurring inside the storage container into a light failure and a serious failure. Various sensors (7) for measuring values, bright color reaction, etc., and a monitoring device (8) for comparing the signal of the sensor (7) with a reference value and transmitting an accident signal are provided. When a certain primary standard value is exceeded, a primary accident signal is sent, and when a secondary fault value, which is a serious failure, is exceeded, a secondary accident signal is sent. There is. On the other hand, in the case where the active material leakage accident of the sodium-sulfur cell (3) occurs in the storage container (2), an inert gas such as nitrogen or argon is supplied to calm the accident. A tank as an active gas supply device (9) is connected, and an automatic opening / closing valve (9b) that is activated by the primary accident signal from the monitoring device (8) is installed in the gas supply pipe (9a). There is.
Similarly, a tank is also connected as an inert coolant supply device (10) that supplies an inert coolant such as sand, silicon oil, and metal digestive agent for calming the accident. At (10a), automatic opening / closing valves (10b) and (10c) that are activated by a secondary accident signal from the monitoring device (8) and a pump as a coolant pressurizing source (11) are installed. Further, in the embodiment, the storage container (2) is provided with the coolant discharge pipe (10d) and the heat exchanger (12).
A circulation path is formed back to the inert coolant supply device (10) with the interposition of. It should be noted that, although the temperature sensor for detecting the operating temperature is used as the sensor (7) in the above-mentioned embodiment, a sensor for detecting the reaction gas, current, voltage, bright color reaction or the like may be used alone or in combination thereof. In addition, in the embodiment, an automatic opening / closing valve (9b) in which the inert gas supply device (9) and the inert coolant supply device (10) are installed as tanks in the gas supply pipe (9a)
It is assumed that the inert gas and the inert coolant are supplied by opening and closing the valve and operating the coolant pressure source (11) installed in the coolant supply pipe (10a). The specific configuration of the inert coolant supply device (10) is not limited to such a configuration, and further, when an inert gas is supplied, it can be applied to individual batteries by interposing a perforated plate such as punching metal. The configuration of the details is arbitrary such that the inert gas is uniformly diffused so that the primary accident handling can be performed more efficiently.

を同時に行なう場合もある。(Operation) With such a configuration, some of the unit cell containers in the storage container (2) are damaged and the active materials Na and S leak out, so that oxygen and oxygen in the storage container (2) When an abnormal overheating phenomenon due to the heat of oxidation reaction occurs, the primary accident signal is issued when the monitoring device (8) exceeds the predetermined primary reference value based on the information from the temperature detection sensor (7). Is transmitted, the predetermined automatic opening / closing valve (9b) is opened based on this primary accident signal, and the inert gas is supplied into the high temperature battery (1) in which the accident occurred. The high temperature air is replaced with an inert gas to suppress the abnormal overheating accident of the unit cell and suppress the sedation by the asphyxiation and cooling effects. After the sedation of the accident, the inert gas is completely discharged from the exhaust pipe (5b), the temperature is raised to the operating temperature, and the operation is restarted. In this case, the inert gas is not polluted. Since it does not have any adverse effect on other healthy, electrically insulating and healthy single cells, normal operation is performed again as a high temperature battery. On the other hand, abnormal overheating and the like cannot be suppressed only by the above-mentioned primary accident treatment by the supply of the inert gas, and the accident spreads to other cells in a chain, and finally the storage container (2) is melted and damaged. If there is a risk of a serious accident such as the spread of heat to adjacent high temperature batteries or equipment, the temperature inside the storage container (2) will continue to rise even after the primary accident, so the information from the sensor (7) Based on the above, a secondary accident signal is transmitted from the monitoring device (8) when a predetermined secondary reference value is exceeded. Then, based on this secondary accident signal, the automatic opening / closing valve (10b) and the coolant pressurizing source (11) are activated, and the predetermined automatic opening / closing valve (10
c) is opened and the inert coolant is supplied into the stationary high temperature battery (1) where the accident occurred, and all the batteries are quickly and surely cooled to the inert temperature by the inert coolant and the accident is sedated. It will be changed to. In this case, since the coolant is configured to circulate in the closed path, it can be efficiently carried out with the minimum necessary amount. As described above, in the present invention, the primary accident treatment by the inert gas is performed as the first step for the abnormal overheating accident that occurs in the stationary high temperature battery (1), and only when the accident is not calmed down. As a second step, the second accident treatment with an inert coolant is carried out to suppress and mitigate the accident, so restarting is possible especially in the case of a minor failure,
It is possible to achieve extremely rational protection of a stationary high temperature battery. In the embodiment, the case of performing the secondary accident process after the primary accident process is described, but in the event of a sudden serious failure, the primary accident signal and the secondary accident signal are simultaneously output from the monitoring device. In some cases, the primary and secondary accident handling may be performed simultaneously.

Especially, in the case of a light accident, only the failed single cell is treated as an accident without losing the overall function, and then restarted. Because it can be done, there are also great economic advantages.
