The fire-fighting infrared temperature-sensing detection alarm is used for detecting the temperature in a short distance through a wire temperature sensor and a pre-buried wire, and in addition, the temperature of a power switch contact is difficult to detect in a common temperature detection mode because the switch works in a high-voltage environment.

The conventional acquisition of temperature measurement work in special occasions such as an ultrahigh voltage environment cannot be realized at all. 3. The traditional temperature sensing cable is easy to age in a high-temperature operation environment, short in service life, inconvenient to replace and easy to generate false alarm. 4. The traditional temperature sensing cable can be installed only when the protected object stops running during installation. 5. The traditional temperature sensing detection period can only carry out close-range close-fitting detection or indoor ceiling-mounted detection temperature alarm, and the temperature can not be remotely detected outdoors. 6. If a temperature sensing system has problems in the operation process, such as disconnection (temperature sensing fault) and other maintenance difficulties, the temperature sensing system can only be carried out after power failure, and the power transformer is generally not allowed to be powered off.
