标准摘要
[中文适用范围]： IEC 60092-302-2:2025 RLV 包含官方的 IEC 国际标准及其红线版本。红线版本仅提供英文版，便于用户快速对比官方 IEC 标准与前一版之间的所有变更。IEC 60092-302-2:2025 规定了低压船舶电力开关设备和控制设备组件（mpsc组件）的具体要求，包括以下内容：- 额定电压不超过 1000 V 交流或 1500 V 直流的带外壳的固定式组件；- 用于与电力的发电、配电和转换以及用于控制电力消耗设备的组件。由于船舶应用及其与断电相关的风险，增加了额外的安全系数，以降低故障风险，如在间隙距离上应用额外的安全系数。本文件适用于所有组件，无论它们是一次性设计、制造和验证的，还是完全标准化并批量制造的。MPSC 组件的制造或组装，或两者均由原始制造商以外的其他方进行。本文件不适用于符合相关产品标准的单独设备和自成一体的组件，例如电机启动器、熔断开关和电子设备。本版取消并替换了 2019 年发布的第一版。本版构成技术修订。与前一版相比，本版包括以下重大技术更改：a) 按照 IEC 61439-1:2020 和 IEC 61439-2:2020 更新的条款进行了修改和更新，并正确引用；b) 增加了对船舶应用需特别考虑的说明；c) 图 201 更新；d) 对爬电距离和间隙距离的“安全系数”进行了调整。 [外文原描述]： IEC 60092-302-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60092-302-2:2025 defines the specific requirements of low voltage marine power switchgear and controlgear assemblies (mpsc-assemblies) as follows: - stationary assemblies with enclosure for which the rated voltage does not exceed 1 000 V AC or 1500 V DC; - assemblies intended for use in conjunction with the power generation, distribution and conversion of electric energy, and for the control of electric energy consuming equipment. Due to the marine application and the risks associated with loss of power, additional safety factors have been applied to minimise the risk of failure, such as applying an additional safety factor on clearance distances. This document applies to all assemblies whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity. Either the manufacture or assembly, or both, of the MPSC assembly can be carried out by others than the original manufacturer. This document does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, which comply with the relevant product standards. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) amended and updated in line with, and correctly referenced to the updated clauses of IEC 61439-1:2020 and IEC 61439-2:2020; b) explanation of the need to special consideration for marine applications added; c) Figure 201 updated; d) adjustment has been made to the "safety factors" for creepage and clearance distances.
