[0003] Switching equipment, thus affecting the safe and stable operation of the power grid

In view of this, it is urgent to develop a low-pressure complete set of ventilation and heat dissipation device that overcomes the above-mentioned defects and discharge heat in time. This case arises from this, and heat dissipation devices generally need to use temperature sensors. In order to achieve rapid detection of temperature, traditional The method is to use heat-conducting materials to package the thermistor in the probe, but the measurement accuracy of the thermistor cannot be further improved
