标准摘要
[中文适用范围]： IEC 60884-2-7:2025 适用于可重接线和不可重接线的电线延长装置，带或不带接地触点，额定电压大于 50 V 但不超过 440 V，额定电流不超过 16 A，用于家庭和类似用途，室内或室外。本文件不适用于带卷绕装置的电线延长装置。用作家具插座的电线延长装置由 IEC 60884-2-8 额外涵盖。本文件还适用于用于电缆卷筒的电线延长装置，因此它们成为带有可拆卸柔性电缆的电缆卷筒。对于电线延长装置的组合，还适用 IEC 61242 的卷筒要求和测试。电线延长装置适合在环境温度通常不超过 +40 °C 的情况下使用，但其 24 小时内的平均温度不超过 +35 °C，环境空气温度下限为 −5 °C。第二版取消并取代了 2011 年发布的第一版和修订 1:2013。此版本构成技术修订。此版本与上一版相比包括以下重大技术变化：a) 与 IEC 60884-1 第四版保持一致。 [外文原描述]： IEC 60884-2-7:2025 applies to cord extension sets, rewirable and non-rewirable, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 16 A, intended for household and similar purposes, either indoors or outdoors. This document does not apply to cord extension sets with means for reeling. Cord extension sets intended to be used as socket-outlets for furniture are additionally covered by IEC 60884‑2‑8. This document also applies to cord extension sets which are intended to be used in a cable reel, and which therefore become cable reels with a detachable flexible cable. For the combination of the cord extension set, the reel requirements and tests of IEC 61242 apply in addition. Cord extension sets are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average temperature over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of −5 °C. This second edition cancels and replaces the first edition published in 2011, and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment to IEC 60884-1, fourth edition.
