船舶电气设施.第507部分:小型船

[中文适用范围]： 概述 IEC 60092 的这一部分规定了小型船舶@长度不超过 50 m@或总吨位不超过 500 总吨 (GT)@设计使用的电气系统的设计@建造和安装要求在内陆水域或海上。它不适用于： a) 仅配备电池供电电路的小型船舶，用于发动机启动和导航照明，由舷内或舷外发动机驱动的交流发电机充电。 b) 船体长度小于 24 m 的休闲船只，需要符合休闲船只指令 94/25/EC 附件 1 基本要求第 5.3 部分电气系统@，但此类休闲船只中以标称运行的三相交流电装置除外电压不超过AC 500 V。 [外文原描述]： IEC 60092-507:2014 specifies requirements for the design, construction and installation of electrical systems in small vessels, which have a length of up to 50 m, or which have a gross tonnage not exceeding 500 Gross Tonnes (GT), designed for use on inland waters or at sea. It is not intended to apply to: a) small craft equipped only with a battery supplying circuits for engine starting and navigation lighting recharged from an inboard or outboard engine driven alternator. b) recreational craft of less than 24 m hull length requiring to conform to the Recreational Craft Directive 94/25/EC Annex 1 Essential Requirements Part 5.3 Electrical systems, except for three-phase alternating current installations in such recreational craft which operate at a nominal voltage not exceeding AC 500 V. This third edition includes the following significant technical changes with respect to the previous edition: a) The standard now clarifies its application for electrical installations in those recreational craft which require to conform to the Recreational Craft Directive. b) The standard specifies requirements for methods of galvanic isolation for small vessels and recreational craft connecting to a low voltage AC shore supply. c) The standard includes design guidance for electric propulsion systems suitable for small vessels and associated installation requirements.
