港口公用设施连接 第3部分：低压岸电连接（LVSC）系统 - 通用要求

[中文适用范围]： IEC/IEEE 80005-3:2025 规定了低压岸电连接系统（LVSC）在船舶和岸上部分的设计、安装和测试要求，以从岸上向船舶提供电力。本文件适用于以下情况： - 在停泊时需要最高达1 MVA电力的船舶； - 额定电流250 A及以上、额定电压为400 V AC至1 000 V AC的三相岸电连接系统； - 岸侧连接系统； - 岸到船的连接及接口设备； - 变压器和电抗器； - 半导体和旋转式频率转换器； - 船侧连接系统； - 保护、控制、监测、联锁和电力管理系统。 本文件不适用于以下情况： - 内河航行船舶； - 高压岸电连接系统，包括按照IEC/IEEE 80005-1附录建造的船舶； - 泊位期间的电力供应，例如干坞作业和其他非运营状态下的维护和修理； - 按照3.19定义的普通人员操作的系统。 [外文原描述]： IEC/IEEE 80005-3:2025 specifies provisions for the design, installation and testing of low-voltage shore connection (LVSC) systems, onboard ships and on shore, to supply the ship with electrical power from shore. This document is applicable to: - ships requiring up to 1 MVA while at berth; - three-phase shore connection systems rated 250 A and above, and with a nominal voltage rating of 400 V AC to 1 000 V AC; - shore-side connection systems; - shore-to-ship connection and interface equipment; - transformers and reactors; - semiconductor and rotating frequency convertors; - ship-side connection systems; - protection, control, monitoring, interlocking and power management systems. This document does not apply to: - inland navigation vessels; - high-voltage shore connection systems, including ships built in accordance with the annexes of IEC/IEEE 80005-1; - the electrical power supply during docking periods, for example dry docking and other out-of-service maintenance and repair; - systems to be operated by ordinary persons as defined in 3.19.
