柴油机电气装置电压

[中文适用范围]： 本 SAE 推荐做法旨在适用于与移动或汽车柴油发动机一起运行的灯、电池、加热器、收音机和类似设备。 24 V 系统长期以来一直用于重型服务，因为 24 V 允许串并联运行 12 V 系统。 32 V 系统已用于船舶、铁路车辆照明和其他用途。发电机、蓄电池、启动电机、照明和辅助电气设备的标称系统额定值为 12、24 或 32 V，具体取决于应用的功率要求。建议不要考虑中间电压。 24 V 启动电机和两个串联连接的 12 V 电池用于启动的组合被认为是一种可以适应安装的实践。电池重新并联连接，用于从 12 V 发电机/交流发电机充电以及用于操作灯和其他辅助设备，或者单独充电并单独用于灯和其他电气设备。 [外文原描述]： This SAE Recommended Practice is intended to apply to lamps, batteries, heaters, radios, and similar equipment for operation with mobile or automotive diesel engines. Twenty-four V systems have long been used for heavy-duty services because 24 V permit operating 12 V systems in series-parallel. Thirty-two V systems have been used for marine, railroad-car lighting, and other uses.Generators, storage batteries, starting motors, lighting, and auxiliary electrical equipment shall be for nominal system ratings of 12, 24, or 32 V as determined by the power requirements of the application. It is recommended that no intermediate voltages be considered.The combination of a 24 V starting motor and two 12 V batteries connected in series for cranking is considered practical where it can be adapted to the installation. The batteries are reconnected in parallel for charging from a 12 V generator/alternator and for operating lights and other auxiliary equipment, or charged separately and used individually for lights and other electrical equipment.Cross Reference:
