自耦式强油风冷变压器冷却系统改造及节能评估

Research on Energy-saving and Transformation in the Cooling System of Forced-oil Air-cooling Auto-type Transformer

自耦式单相强油风冷有载调压变压器冷却系统在运行中存在较多缺陷,可将变压器冷却系统改造为油浸自然循环风冷系统。结合实际情况,开展自耦单相强油风冷有载调压变压器冷却系统的改造及节能效益评估研究,可知此类冷却系统改造对于提高设备可靠性、减少电量损耗、节约检修成本具有重要意义。

There are many defects in the operation of auto single-phase forced-oil air-cooling transformer with on-load tap changer. The cooling system for the transformer can be transformed into oil natural air forced cooling system. Combined with the actual situation, research on cooling system transformation and energy-saving effect of the auto single-phase forced-oil air-cooling transformer with on-load tap changer was carried out, which shows that such a cooling system transformation was significant for improving equipment reliability, reducing power consumption, and saving cost of overhaul.
