浅谈油浸自冷变压器冷却系统优化方案

Discussion on the Cooling System Optimized Scheme for Oil-immersed Natural Cooling Transformer

通过对运行中的大容量油浸自冷变压器异常温升情况的分析,从变压器温升的理论计算、设计思路和实践效果等方面论证了抬高散热器中心可以有效地降低变压器温升,从而达到延长变压器运行寿命的目的,对于环境温度较高的地方可以通过降低温升设计值来保证变压器运行温度不超过规定值。

This paper analyses the abnormal temperature rise of large oil-immersed natural cooling transformers in operating. The temperature rise can be reduced by rising the height of the radiator center according to the theoretical calculation design thinking and effect of practice. The transformer life can be prolonged because of the reduction of temperature rise. It is possible that the temperature does not exceed the rating at the higher ambient temperature by reducing the designed oil temperature rise value.
