Transformer and NTC temperature sensor.Human Body Temperature Monitoring Sensor

　　A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It has a wide range of applications and is an indispensable electrical equipment in the current power supply network system. The transformer heating device is installed inside the box, with a one-way valve connected to a heating tube, and an NTC temperature sensor installed on the heating tube; A one-way valve is installed at the bottom of the oil storage tank to allow transformer oil to enter the heating tube under atmospheric pressure. An electric heating wire is installed inside the heating tube, and the NTC temperature sensor temperature measuring element is located inside the heating tube. Through temperature detection, when the oil temperature of the transformer oil is lower than the separation temperature, the controller energizes the electric heating wire to heat the transformer oil. Generally, the oil temperature of the transformer oil during operation is 40-60 ℃, Satisfying the oil temperature for vacuum separation of oil and water, the electric heating wire does not start, which can save electricity.

　　A ring-shaped NTC temperature sensor, packaged with high-precision thermistors and high thermal conductivity wires, can accurately monitor the temperature of transformers with high accuracy; It has a fast reaction speed and can quickly detect transformer oil temperature; It is packaged with a high waterproof glass sealed resistor and can be used in harsh environments such as high temperature and humidity; Suitable for transformer temperature monitoring.
