New product for detecting abnormal temperatures in electrical equipment of solar power generation systems / temperature detection sensor for power generation.

Detection of abnormal temperatures in electric vehicle (EV) electrical equipment circuits / New product for temperature detection sensors for EVs

1. The abnormal temperature of the power circuit's wires can be monitored and detected on a daily basis. 2. The abnormal heat generation (abnormal temperature) of control devices, load devices, and storage batteries can be monitored and detected on a daily basis. 3. The inspection of electrical circuits can be performed by anyone. Additionally, maintenance management can be carried out reliably and safely. 4. It is possible to prevent fires caused by abnormal temperatures in electrical equipment that could lead to recalls. 5. Safety management for electric vehicles (EVs) is enhanced, allowing for safe driving of electric vehicles (EVs). 6. By utilizing shape memory alloys (restoration) and wires (softening) to create a short circuit (contact) between two wires, abnormal temperatures (maximum allowable temperature) can be detected and signaled. [Set temperature 70°C] 7. This is an eco-technology product that is simple, easy, accurate, and has a switching function that results in zero standby power. 8. It can detect temperature and signal simultaneously, with a simple circuit configuration (switching function) at a low cost. 9. Shape memory alloys have permanent memory, are rust-free, and maintain their state once activated indefinitely. 10. Operation is a physical action that does not require power, has no malfunction, and can be used for many years with speed and accuracy. 11. Temperature detection can be performed directly without the need for measuring instruments. 12. It is a non-reset type that allows for confirmation after operation. (Once activated by detection / cannot be reset. Delete the activated area and change the connection.)

New product for detecting abnormal temperatures in electrical equipment / temperature detection line.

■Characteristics of Temperature Detection Lines 1. Abnormal temperatures of electrical wires can be monitored regularly and detected collectively. 2. Abnormal temperatures of power (control) equipment and electrical (load) equipment can be monitored regularly and detected collectively. 3. Wiring similar to that of electrical equipment can be achieved. 4. By utilizing shape memory alloy (restoration) and electrical wires (softening) to create a short circuit (contact) between the two wire cores, abnormal temperatures are detected and converted into signals. 5. It is a simple, easy, and accurate eco-technology product with zero standby power due to its switching function. 6. It can detect temperature and signals simultaneously, with a simple circuit configuration (switching function) at a low cost. 7. Shape memory alloy has permanent memory, is rust-free, and retains its shape indefinitely once activated. 8. The operation is a physical action that does not require power, ensuring no malfunction, and it can be used accurately and swiftly for many years. 9. Temperature detection can be performed directly without the need for measuring instruments. 10. It can be used for indoor and outdoor wiring. 11. It is a non-return type that allows for confirmation after activation. (Once sensing is activated / cannot be reactivated. The activated area can be deleted and reconnected.)
