摘　　要：在电化区段由接触网向客车供电的有关技术要求为:列车干线电压采用50m单相交流电,电压为3000V或1500V。列车用电量对北京南、北空调列车为800～1000kVA,采用一路干线供电,使用一线一地制;车辆每端设置两个电力连接器并联工作;每辆客车上设置25～30kw的静止变流器;电热器由变流器的降压变压器降压供电;通风机与照明由蓄电池供电;在列车运用于非电化区段时,由电压为单相1500V或3000V的发电车供电。On electrified sections,the technical requirements on the coach power supplying by the contact net are:the train main supply line having aingle phase alternating current with a frequency of 50Hz and a voltage of 3000V or 1500V; the power consumption of air-conditioning trains running south of Beijing being 800kW,those running north of Beijing 1000kW; one main supply line being provided for the train, that in, a live wire and the rail (?) ground wire; two electric connectors being shunted together on each end of a coach; a 25-30kW static convertor being provided for each coech; the electric hoater being supplied with current of dropped voltage by the step-down transformer in the convertor; the ventilator and lighting being supplied by the storage batteries; the train being supllied by the generator car with single phase current of a voltage of 1500V or 3000V while running on non-electrified sections.
