Dry type transformers are widely used, especially in sensitive situations such as mining, chemical, railway, military, etc. Due to the special nature of their operating environment, temperature control is very important.
The dry type transformer produced by Hengfengyou Electric is a type of transformer that uses dry insulation materials as the insulation medium. Its main characteristics are good insulation effect, good combustion performance, stable insulation performance, and good environmental protection performance. When a dry-type transformer is in operation, it generates a certain amount of heat, which can be dissipated through ventilation and heat dissipation. However, if the temperature is too high, it can easily damage the insulation material of the dry-type transformer, leading to equipment failure.
So, what is the appropriate temperature control for dry type transformers? This question is actually not a simple answer. Because the design and operating environment of dry-type transformers can affect their operating temperature. Generally speaking, the operating temperature of dry-type transformers should be between -25 ℃ and 45 ℃, and a better operating temperature should be between 30 ℃ and 35 ℃.
In practical use, Jack, the sales director of Hengfengyou Electric, introduced several ways to control the temperature of dry-type transformers:
1. Install wind blades or fans
By installing ventilation equipment such as wind blades and fans, air circulation can be accelerated, heat dissipation efficiency can be improved, thereby reducing heat accumulation and lowering temperature.
2. Use materials with good insulation and heat resistance performance
The use of materials with good insulation and heat resistance can increase the thermal stability of dry-type transformers, improve their ability to withstand higher temperatures, and ensure the long-term operational stability of the equipment.
3. Reduce load rate
Generally, under the Nameplate capacity of dry-type transformer, the recommended load rate is between 70% and 80%. If the transformer is overloaded, it will generate a lot of heat, which will increase the burden of the equipment, resulting in excessive temperature.
4. Regular inspection and maintenance
Regular inspection and maintenance of dry-type transformers can promptly identify faults and repair and maintain equipment, thereby ensuring long-term stable operation of the equipment.
In summary, it is more suitable to control the temperature of dry type transformers between 30 ℃ and 35 ℃. By installing wind blades or fans, using materials with good insulation and heat resistance, reducing load rates, and conducting regular inspections and maintenance, the temperature of dry-type transformers can be effectively controlled to ensure stable operation of the equipment.
