【発明の詳細な説明】
（産業上の利用分野）

（従来の技術）
高温電池装置は３００〜３５０°Ｃ程度の高温に保たれ

できる電池装置として注目されている。(Prior art) A high-temperature battery device is an arrangement in which a large number of, for example, sodium-sulfur cells are connected and arranged inside an insulated container kept at a high temperature of about 300 to 350°C, and can store a large amount of electric power. It is attracting attention as a battery device.

ずる。However, if the container for such a single cell is damaged for some reason, the active materials, such as sodium and sulfur, may leak out, potentially causing a fire due to abnormally high temperatures. In order to quickly deal with such fires, it is being considered to install a large number of sensors such as thermocouples inside the heat insulating container to immediately detect the occurrence of abnormally high temperatures and cool the container. However, even if a large number of thermocouples and the like are to be arranged inside an insulating container with limited space, it is not easy to draw out the lead wires, and the structure becomes extremely complicated.
このために従来は断熱容器の内部における異常発生を正
確に検出する手段を持つ高温電池装置は知られておらず
、断熱容器の外部に異常検出センサを取り付けざるを得
なかったので、検出の遅れが避けられない欠点があった
。For this reason, until now, no high-temperature battery device was known that had a means to accurately detect the occurrence of an abnormality inside an insulated container, and an abnormality detection sensor had to be attached to the outside of the insulated container, resulting in a delay in detection. However, there was an unavoidable drawback.

ワイヤーとしての機能が発揮される。In the present invention, a single temperature detection wire (4) is stretched around the inside of the heat insulating container (1). The battery is 43
If the temperature exceeds 0°C to 450°C, there is a risk that the container will be damaged and the active material will leak. For this reason, this temperature detection wire (4) is made of, for example, a 380% metal such as a lead-tin alloy or a zinc alloy.
It is made of a material that melts at a temperature of about 430° C. and can melt when the cell (2) becomes abnormally heated. For example, as shown in Figure 2, the temperature detection wire (4) may be passed through the bottom of each cell (2) in a zigzag pattern depending on the arrangement of the cells (2), or may be placed around each cell (2). It is preferable to wind them in order. Furthermore, this wire can function as a detection wire by insulating it with a highly heat-resistant glass coating.

A detection circuit (6) for detecting the position is connected. The disconnection detection circuit (5) connects the temperature detection wire (4
) A commercially available device can be used that can detect the presence or absence of disconnection by passing a minute current through the wire. The detection circuit (6) also connects the pulse generator to the temperature detection wire (4).
The fuse position can be detected by sending a pulse to one end of the fuse and using the time difference until the reflected pulse returns from the other end.
