    Since August, high temperature warnings have been issued in many places across the country. The local area exceeds 40°C, and the electricity load continues to increase. In addition, in severe weather such as high temperature, equipment is prone to and multiple hidden dangers, and the safety risk is also greater. In order to ensure the power supply in summer during peak seasons, some places adopt off-peak power consumption, and some places adopt replacement of large transformers. No matter what measures are taken, the safety role of the NTC temperature sensor that monitors the temperature in the transformer is very important.

    The transformer is the "heart" of the substation. During the peak period of electricity consumption in summer, the main transformer is close to full load operation. Using the NTC temperature sensor, the working temperature of the transformer can be monitored in real time, its temperature distribution and temperature value can be visually displayed, and the overheating of the transformer can be detected in time, so that multiple measures can be taken to help it "fever and cool down". At the same time, it can also quickly find the hidden danger of overheating and deal with it 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. Higher requirements are also placed on the sensitivity, moisture resistance and ease of installation of NTC temperature sensors. Nanjing Shiheng Electronics produces NTC temperature sensors used in transformers for precise temperature control, which is safe and reliable. The parameters of the CWF4 temperature sensor are 103K, the accuracy is ±1%, the B value is 3950, and the product withstand voltage can reach 8000V/AC. Brass nickel-plated OT end is used, and the wire is made of PVC wire. The operating temperature of the product is between -40°C and 150°C. It has the advantages of small size, high temperature measurement accuracy, fast response speed, product moisture resistance, high water resistance, and simple assembly method. , firm and other characteristics. In order to ensure the safe operation of the transformer, the CWF4, 103F3950 NTC temperature sensor from Nanjing Shiheng Electronics can be selected.
