When we use dry-type transformer in our production and life, it is used indoors. In fact, dry-type transformer is also installed outdoors, but there are some conditions, and some even need to be maintained to avoid such or such problems. Dry type transformer can be placed outdoors. Let's introduce the details
差，会要求干式变压器外绝缘性能较高之。 3、防护等级会有所不同，考虑室外安全性能的不同，会要求干式变压器防护等级稍高。 注：室外的干式变压器(用电大功率器材)也不可避免会引雷。要做好防雷准备。雷击损坏配变过去单纯认为是雷电波进入高压绕组引起，实际上这种认识带有程度的片面性。理论分析和实际试验表明：配变雷害事故的主要原因是由于配电系统遭受雷害时的“正反变换”的过电压引起，而反变换过电压损坏事故尤甚。现就正反变换过电压发展过程进行分析，讨论配变的防雷保护。 以上是常见的干式变压器放在室外的主要的介绍供大家进行参考，对于干式变压器您还有什么其他的问题的话请咨询我们的工作人员!)
Dry type transformer should be placed outside and in the open air
1. The difference between temperature rise and heat dissipation, especially for dry-type transformer with natural heat dissipation, makes it better outdoors.
2. Considering the poor outdoor insulation environment (pollution level), the external insulation performance of dry-type transformer will be higher.
3. The protection level will be different. Considering the different outdoor safety performance, the protection level of dry-type transformer will be slightly higher.
Note: outdoor dry-type transformer (high-power equipment) will inevitably lead to lightning. We should be prepared for lightning protection. In the past, the distribution transformer damaged by lightning was simply thought to be caused by lightning wave entering the high voltage winding. In fact, this understanding is one-sided. Theoretical analysis and practical test show that the main cause of distribution transformer lightning damage accident is caused by the "positive and negative transformation" overvoltage when the distribution system suffers from lightning damage, especially the reverse transformation overvoltage damage accident. This paper analyzes the development process of positive and negative transformation overvoltage, and discusses the lightning protection of distribution transformer.
The above is the main introduction of the common dry-type transformer outdoor for your reference. If you have any other questions about the dry-type transformer, please consult our staff!
