Temperature detection sensor for storage batteries

1. This is a product with a temperature detection sensor connected by a code. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor is equipped with a shape memory alloy coiled around a soluble insulated wire. When the surrounding temperature reaches the set temperature (80°C), the wire softens, and the shape memory alloy constricts the wire (restores), short-circuiting the two wires to detect temperature and signal it (no voltage/a contact) as temperature detection. 3. By setting the temperature detection sensor to the abnormal temperature of the equipment, it can detect abnormal temperatures. In other words, by installing temperature detection sensors on various industrial and equipment devices, it can detect abnormal temperatures that may lead to equipment damage or fire. Set the abnormal temperature to the set temperature (80°C). 5. For example, when installed on various industrial and electrical equipment, if abnormal heat (abnormal temperature) occurs, the temperature detection sensor with a code detects the abnormal temperature and alerts through an alarm or similar device. 6. In this way, abnormal temperatures of various industrial and electrical equipment can be continuously monitored on a daily basis, allowing for early detection and preventing equipment damage or fire through initial response. Maintenance management is reliable and safe.

This device is a "battery alarm system" that allows for easy monitoring and alarming of abnormal temperatures in batteries by attaching a temperature sensing wire to the battery and connecting it to a small alarm panel. The temperature sensing wire is structured by combining numerous shape memory alloys at equal intervals along an extended wire. When the surrounding temperature reaches the set temperature (70°C), the two wires short-circuit to generate a temperature sensing signal. Installation is completed simply by extending the wire, and it employs eco-technology with zero standby power for the switching function, making it easy for anyone to use. This product meets the performance standards of a fixed temperature type detector (120 seconds) as specified by fire safety regulations and is ideal for the regular monitoring of abnormal temperatures in batteries and battery systems. ■ Contact information regarding this matter 2-2-8 Minami Tsutsujigaoka, Kameoka City, Kyoto Prefecture 621-0847 Space Works Contact: Wada wadakame@siren.ocn.ne.jp TEL: 0771-25-3430 / FAX: 0771-25-4932

■Overview of Temperature Detection Line 1. This product integrates a large number of shape memory alloys (temperature detection sensors) at equal intervals along an extended electric wire. However, it is designed to correspond to the maximum allowable temperature of the electric wire. 2. This maximum allowable temperature is the temperature at which the insulation of the wire rapidly deteriorates. The set temperature corresponds to the maximum allowable temperature product (70°C). 3. By detecting the maximum allowable temperature of the electric wire, it can detect abnormal temperatures associated with fire hazards in electrical equipment. 4. The temperature detection line is attached to the electric wire to collectively detect abnormal temperatures caused by overload currents or poor connections in the electric wire for each temperature detection line. (Abnormal temperature detection of the electric wire) 5. Temperature detection lines are installed inside and outside power (control) devices and electrical (load) devices to collectively detect abnormal temperatures caused by overloads or device failures for each temperature detection line. (Abnormal temperature detection of devices) 6. For example, when an abnormal temperature associated with a fire occurs in electric wires or power (control) devices and electrical (load) devices, the temperature detection sensors attached to each temperature detection line continuously monitor and collectively detect the abnormal temperatures. Alarms and other devices notify of abnormal temperatures associated with fire hazards.

■Overview of Temperature Detection Sensor for Storage Batteries 1. This is a product with a code connected to the temperature detection sensor. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor integrates a shape memory alloy with a wire, utilizing the softening of the wire and the restoration of the shape memory alloy to create a short circuit (contact) between the two wire cores, thereby detecting the maximum allowable temperature and generating a signal. The set temperature corresponds to the maximum allowable temperature of the wire (70°C). 3. The maximum allowable temperature is the temperature at which the insulation of the wire rapidly deteriorates. Therefore, detecting the maximum allowable temperature indicates the detection of abnormal temperatures in the wire. 4. Mounted on the outer wall of the storage battery, it detects abnormal heat (abnormal temperature) due to internal short circuits, external short circuits, and external overheating, and alerts through alarms to prevent fires caused by ignition or explosion. 5. For example, when abnormal heat (abnormal temperature) occurs in a storage battery, the temperature detection sensor mounted on the outer wall of the battery detects the abnormal temperature and alerts through alarms. 6. In this way, it is possible to continuously monitor the abnormal heat (abnormal temperature) of the storage battery and the abnormal temperature of the wires and electrical equipment in the charging/discharging circuit of the battery system, thereby preventing equipment damage and fires. Maintenance management can be conducted reliably and safely.
