Application of Organic Silicone Antifreeze in the Temperature Measurement System of Transformer

Abstract

Transformer in the operation process, iron core, winding and steel structure to produce loss. These losses will produce heat, leading to the transformer temperature rise, the aging of insulation materials to accelerate, the transformer's service life is shortened. In order to ensure that the temperature of each component of the transformer is not more than the limit value, the service life of the transformer is prolonged, and the temperature measuring device must be installed. The temperature measuring device is used to monitor the temperature and temperature change of the transformer. The existing temperature measuring device has the problem of bad sealing, and the water enters the temperature measuring device through the temperature measuring hole. In winter, the water is converted into ice, and the thermometer is easily cracked, leading to the failure of the function of the temperature measuring device. An effective method is described in this paper to avoid the thermometer being ruptured. Because the performance and density of anti freezing agent is better than that of transformer oil, special anti freeze agent is used to replace transformer oil in the temperature measuring hole. So, completely solve the problem of the thermometer damage accident.
