摘要:
The invention relates to an autotransformer (AT) traction power supply system equipped with 2×27.5kV outdoor modularized electric apparatus, comprising a traction substation located beside an electrified railway, which connects with an up / a down line traction network at output terminal, a parallel apparatus located in the middle and the end of a feeder in the up / down line traction network, which functions as parallel power supply, and an over-zone apparatus located around a neutral section insulator between feeders of the up / down line traction network of two adjacent traction substations, which functions as over-zone power supply. The parallel apparatus connected with an AT apparatus is a modularized electric apparatus which comprises four parallel power supply units. The AT apparatus comprises four integrated AT substations which include the first AT transformer, the second AT transformer and an AT modularized electric apparatus. The invention has the advantages of covering small area, lower investmen
