摘要

An AC-DC electric power converting station is provided wherein circuit lines consisting of converter transformers/ positive and negative polarity valve structures/ DC reactors/ DC circuit breakers are of L-shape and inverted L-shape. The positive and negative polarity valve structures are so arranged that their surfaces in the longitudinal direction face each other. The converting transformers are arranged along the other surfaces of the positive and negative polarity valve structures in the longitudinal direction thereof. The DC reactors and DC circuit breakers are series-connected in the vicinities of the outputs in the direction of width of the positive and negative polarity valve structures. AC and DC switchgears of gas insulated type are arranged to face each other so that they sandwich the positive and negative polarity valve structures therebetween. Conduit air cables connect the positive and negative polarity valve structures and the AC and DC switchgears.
