标准摘要
[中文适用范围]： IEC 60664-1:2020+AMD1:2025 CSV 涉及连接到低压供电系统的额定电压高达交流 1 000 V 或直流 1 500 V 的设备的绝缘协调。本文件适用于高达 30 kHz 的频率。它适用于海拔 2,000 米以下使用的设备，并为在更高海拔地区使用提供指导。它为技术委员会确定电气间隙、爬电距离和固体绝缘标准提供了要求。它包括与绝缘配合有关的电气测试方法。本文件中指定的最小间隙不适用于存在电离气体的地方。相关技术委员会可酌情指定此类情况的特殊要求。本文件不涉及以下距离： – 通过液体绝缘； – 通过空气以外的气体； – 通过压缩空气。此版本相对于前一版本包括以下重大技术变化：更新范围、第 2 和 3 条、在表格中添加 1 500 V DC、第 4 和 5 条的新结构、添加带有间隙流程图的附件 G、添加带有爬电距离流程图的附件 H、在新表 F.10 中更新距离高度校正。根据 IEC 指南 104，它具有基本安全出版物的地位。 [外文原描述]： IEC 60664-1:2020+AMD1:2025 CSV deals with insulation coordination for equipment having a rated voltage up to AC 1 000 V or DC 1 500 V connected to low-voltage supply systems. This document applies to frequencies up to 30 kHz. It applies to equipment for use up to 2 000 m above sea level and provides guidance for use at higher altitudes. It provides requirements for technical committees to determine clearances, creepage distances and criteria for solid insulation. It includes methods of electrical testing with respect to insulation coordination. The minimum clearances specified in this document do not apply where ionized gases are present. Special requirements for such situations can be specified at the discretion of the relevant technical committee. This document does not deal with distances: – through liquid insulation; – through gases other than air; – through compressed air. This edition includes the following significant technical changes with respect to the previous edition: update of the Scope, Clauses 2 and 3, addition of 1 500 V DC into tables, new structure for Clauses 4 and 5, addition of Annex G with a flowchart for clearances, addition of Annex H with a flowchart for creepage distances, update of distances altitude correction in a new Table F.10. It has the status of a basic safety publication in accordance with IEC Guide 104.
