The invention discloses a rail transit power supply system based on a three-phase inverter power supply device, and aims to effectively simplify the whole power supply system scheme, reduce the number of medium-voltage ring network cables and equipment, and greatly reduce the construction scale of each substation and the engineering investment of the whole power supply system. The rail transit power supply system comprises a traction power supply system and a low-voltage power supply and distribution system, two external incoming line power supplies are introduced from a local power grid, power is supplied to a plurality of traction and voltage reduction hybrid substations and voltage reduction substations along a project through a medium-voltage power supply looped network, the two external incoming line power supplies are respectively introduced into a substation medium-voltage I-section bus through substation medium-voltage switches, and the medium-voltage power supply looped network is connected with the substation medium-voltage I-section bus of the traction and voltage reduction hybrid substation and a voltage reduction substation along a project through a substation medium-voltage switch.

    一种基于三相逆变电源装置的轨道交通供电系统,以有效简化整个供电系统方案、减少中压环网电缆及设备数量,大幅降低各变电所的建设规模及整个供电系统的工程投资。包括牵引供电系统和低压供配电系统,从地方电网引入两回外部进线电源,通过一个中压供电环网向工程沿线若干个牵引降压混合变电所和降压变电所供电,该两回外部进线电源分别通过变电所中压开关引入变电所中压I段母线,该中压供电环网通过变电所中压开关与工程沿线的牵引降压混合变电所和降压变电所的变电所中压I段母线相连。
