The invention discloses an alternating-current deicing and anti-icing method for an overhead line system of an electrified railway, which comprises the following steps: on the basis that a traction substation has two sets of traction transformers (a main transformer and a standby transformer), matching of primary side joints of the two transformers (that is, the main transformer is connected with a main joint and the standby transformer is connected with a tap; or the main transformer is connected with the tap and the standby transformer is connected with the main joint, or the main transformer and the standby transformer are connected with different taps) to change the output voltage, so that a voltage difference exists between the secondary side voltage of the main traction transformer and the secondary side voltage of the standby traction transformer, and ice melting and ice prevention are realized without additionally using ice melting and ice prevention equipment; the investment cost is saved; in addition, the locomotive can also operate in the ice-melting and anti-icing traction network section.
本发明公开了一种电气化铁路接触网交流融冰、防冰方法,基于牵引变电所自身有两套牵引变压器(主变压器和备用变压器),利用两变压器一次侧接头的配合(即主变压器连接主接头而备用变压器连接分接头,或者主变压器连接分接头而备用变压器连接主接头,或者主变压器和备用变压器连接不同的分接头)改变输出电压使主牵引变压器二次侧电压与备用牵引变压器二次侧电压存在电压差,以此实现融冰、防冰,不需要额外投入融冰、防冰设备,节省了投资成本;并且,机车也可以在融冰、防冰的牵引网区段内运行。
