Since August, many regions throughout the country have continuously issued high temperature warnings. The local temperature is over 40 ℃, and the power load continues to increase. In addition, equipment is prone to occur and more hidden dangers occur in severe weather such as high temperature, so the safety risk is even greater. In order to ensure the power supply in summer, some places adopt off peak power consumption, and some places adopt replacement of large transformers. No matter what measures are taken, the NTC temperature sensor monitoring the temperature in the transformer plays a very important role in safety.
The transformer is the "heart" of the substation. In summer, the peak period of power consumption is long, and the main transformer is running close to full load. The NTC temperature sensor can be used to monitor the working temperature of the transformer in real time, visually display its temperature distribution and temperature value, and timely find the overheating of the transformer, so as to take multiple measures to help it "reduce the temperature". At the same time, it can also quickly find out the potential overheating points and deal with them as soon as possible to ensure the safe operation of the transformer.
With the rapid development of transformers, it is a development trend that internal components require safety and small size. It also puts forward higher requirements for the sensitivity, moistureproof property and easy installation of NTC temperature sensor. Nanjing Shiheng Electronics produces NTC temperature sensor for transformer to control temperature accurately, which is safe and reliable. The parameter of CWF4 temperature sensor is 103K, the accuracy is ± 1%, the B value is 3950, and the withstand voltage of the product can reach 8000V/AC. Brass nickel plated OT end is used, PVC wire is used, and the product temperature is between - 40 ℃ and 150 ℃. It has the characteristics of small size, high temperature measurement accuracy, fast reaction speed, high moisture resistance and water resistance, and simple and firm assembly. In order to ensure the safe operation of the transformer, Nanjing Shiheng Electronics CWF4103F3950NTC temperature sensor can be selected.
