基于东南亚热带季风气候下光伏箱变的故障处理

Troubleshooting of Photovoltaic Box Variables Based on the Tropical Monsoon Climate of South-east Asia

热带季风气候的气候特征是终年高温,年平均气温在22℃以上,降水分旱雨两季,在雨季时一般平均湿度比较常落在50%~75%之间,这就要求此地区工作的电气设备既要具有良好的通风降温设计,又要有较好的防雨设计,对箱变的生产厂家和设计院提出了较高的要求。在某东南亚光伏项目上出现的箱式变压器的典型故障,分析了故障原因,为以后的工程提供帮助和借鉴。

The climate of the tropical monsoon climate is characterised by high temperatures throughout the year,the average annual temperature is above 22℃,precipitation is divided into dry and rainy seasons,in the rainy season when the average humidity is generally more often falls between 50%~75%,which requires this area of the work of the electrical equipment should be both good ventilation and cooling design,but also have a better design of the rain,the box transformer manufacturers and design institutes put forward a higher demand.Typical failures of box transformers on a Southeast Asian photovoltaic project,the causes of failure are analysed to provide help and reference for future projects.
