然而在配电等级，联络开关用来开合同一变电站中不同变压器上的馈线或馈线段，或切换到邻近变电站以进行变电站变压器的负荷管理。

However, at the distribution level, 'tie switches are used to switch feeders or feeder sections between transformers in the same station, or to adjacent substations for substation transformer load.

例如，因为温度的不断增高，变压器可能出现较高的失效率，而某些类型的火力发电站的效能也可能会显著的降低。

For instance, transformers could suffer higher failure rates and efficiency of some types of thermal power station could be markedly reduced because of increasing temperatures.

一个新的发电站将被建立，它有两个变压器，图中所示就是其中之一。

A new electric station was built. It has two electric transformers, one of which is shown in the picture.
