变压器的外观是一种外面连有许多垂直管子的容器，容器里面装满着一种叫做变压器油的石油产品。

The appearance of the transformer is a container with many vertical pipes connected to the outside, and the container is filled with a kind of petroleum product called transformer oil.

变压器中的线圈和硅钢片全都浸泡在变压器油中，用油来吸收它所放出的热量。当变压器油通过变压器外面的管子对流流动时，就会把热量散发到周围的空气中去，这样便可保持变压器中的油温不会太高。

The coil and silicon steel sheet in the transformer are all immersed in the transformer oil to absorb the heat released by it. When the transformer oil flows by convection through the pipes outside the transformer, it will dissipate heat to the surrounding air, so that the oil temperature in the transformer will not be too high.

因此，变压器油是作为一种把变压器产生的热量散发到空气中去的一种中介媒体。

Therefore, transformer oil is used as a medium to dissipate the heat generated by the transformer into the air.
         

如果变压器油失效，变压器就失去保护，因此对变压器进行维护中，要选择优良的变压器油。

If the transformer oil fails, the transformer will lose its protection. Therefore, in the maintenance of the transformer, excellent transformer oil should be selected.
