How to choose the right dry type transformer？
Selecting the right dry type transformer is a comprehensive process that requires consideration of multiple factors to ensure that the selected transformer meets actual needs and operating conditions. The following are some key factors in selecting a dry type transformer.
1. Current load capacity
When choosing a dry type transformer model, the first thing to consider is the current load capacity. Because only by choosing a model with appropriate current load capacity can the use needs be met and problems such as overvoltage and excessive loss be avoided. Therefore, when choosing a model, it is necessary to comprehensively consider factors such as the power size and current size of the electrical equipment used.
2. Temperature rise index
Temperature rise is an inevitable problem in the operation of dry type transformers. The temperature rise index of a good dry type transformer should not be too high in long-term use, otherwise it will affect the safety performance of the equipment. The temperature rise index of a poor-quality transformer will exceed the standard in a short period of time, which requires us to choose the corresponding model. In general, the temperature rise index of a dry type transformer should not be too high, and products with good quality should be given priority when choosing.
3. Insulation level
The internal insulation level of dry type transformers is one of the factors that must be considered during use. This parameter affects the safe operating range and working environment of dry type transformers. Improper insulation level selection will damage the equipment safety of dry type transformers, reduce the working environment and service life of the equipment. Configuring the appropriate insulation level under each power supply condition is the key to ensuring safe and intact equipment operation.
4. Natural air cooling or forced air cooling
Dry type transformers generally have two cooling methods, one is natural air cooling and the other is forced air cooling. Natural cooling is usually suitable for use under low power, low ambient temperature, and no overly strict cooling conditions, while forced air cooling is suitable for use under high power and high temperature environments. When choosing, it is necessary to comprehensively consider factors such as the actual use environment and power.
5. Brand and quality
First, choose transformers produced by well-known brands and reputable manufacturers, which usually have higher quality and better after-sales service. Second, make sure that the selected transformer meets the relevant national standards and industry standards and has passed the necessary quality certification and testing.
Choosing the right dry type transformer is a complex and important process. By clarifying the needs, evaluating technical parameters and performance, considering factors such as brand and quality, and installation and maintenance, you can ensure that the selected transformer can perfectly adapt to the actual application scenario. When selecting, you should consider multiple factors to ensure that the selected equipment can meet the stable operation requirements of the power system and reduce energy consumption and maintenance costs. At the same time, you should also pay attention to the energy efficiency level and environmental performance of the transformer to comply with the national energy conservation and emission reduction policies.
