摘　　要：通过几个工程实例,阐述了将ODAF冷却方式的大型电力变压器改造为ONAN/ONAF冷却方式的技术关键和实施方法。指出其改造的意义不仅节能,减轻运行维护工作量,而且从本质上提高变压器的运行可靠性,为建设无人值守变电站创造必要的条件。With several engineering practices as example,the technical key point and substantial method of reforming the cooling system from ODAF into ONAN/ONAF for a large power transformer is formulated.And it is pointed out that the significance of this innovation is not only energy saving and operation maintenance work reducing,but also raising up the running reliability essentially,providing necessary basis for the construction of unmanned substation.
