103机车为高速客运电力机车,轴功率为1240千瓦,仅次于E120机车;全车功率为7440千瓦,是目前功率最大的电力机车。机车在牵引400吨的客车时,174秒后就可达到200公里/小时的速度。103118号机车改变了传动比,结构速度可达250公里/小时。机车采用传统的单相交流低频电路,没有中间整流环节。圆盘式高压调压开关有0～39个触头,触头间用晶闸管作负荷转换开关,从而改善了性能,减少了维护。机车装有一台WFUR1563V/15V三柱芯式变压器。调节绕组、辅助绕组和取暖绕组
103 locomotive is a high-speed passenger electric locomotive with a shaft power of 1240 kilowatts, second only to the E120 locomotive. The whole car has a power of 7440 kilowatts and is currently the largest electric locomotive. The locomotive can reach a speed of 200 km / h after 174 seconds when pulling a 400-ton passenger car. No. 103118 locomotive changed the transmission ratio, the structure speed of up to 250 km / h. Locomotive using the traditional low-frequency single-phase circuit, there is no intermediate rectifier links. Disc pressure switch has 0 to 39 contacts, contact between the thyristor load changeover switch, thus improving the performance and reduce maintenance. Locomotive equipped with a WFUR1563V / 15V three-column core transformer. Regulating windings, auxiliary windings and heating windings
