变压器台数应根据负荷特点和经济运行要求进行选择。当符合下列条件之一时，

The number of transformer stations should be selected according to the characteristics of load requirements and economic operation. When one of the following conditions should be used and two or more transformers: <br>1, although a large number of two loads or one load, but there is a certain amount of electricity fire fighting equipment, security equipment; <br>2, concentrated load is large, required transformer capacity exceeds 500 kA, can use two small-capacity transformer, in order to ensure security of supply; <br>3, large seasonal load changes, may be provided on two or more transformers, so that the whole transformer resectable during the low season .

变压器台数应根据负荷特点和经济运行要求进行选择。当符合下列条件之一时，宜采用两台及以上变压器：<br>1、有大量一级负荷或者虽为二级负荷，但有一定数量的消防设备、保安设备等用电；<br>2、集中负荷较大，所需变压器容量超过500kA时，可选用两台小容量变压器，以确保供电安全；<br>3、季节性负荷变化较大时，可设两台或两台以上变压器，以便在淡季时可切除整台变压器。

The number of transformers shall be selected according to load characteristics and economic operation requirements. When one of the following conditions is met, two or more transformers should be used:<br>1. There are a large number of primary load or secondary load, but there are a certain number of fire-fighting equipment, security equipment and other electricity;<br>2. When the centralized load is large and the required transformer capacity exceeds 500ka, two small capacity transformers can be selected to ensure the power supply safety;<br>3. When the seasonal load changes greatly, two or more transformers can be set, so that the whole transformer can be cut off in the off-season.<br>
