超高压交流输电系统 第301部分：现场验收试验

[中文适用范围]： IEC TS 63042-301:2026 RLV包含国际电工委员会（IEC）官方国际标准及其红线版本。红线版本仅提供英文，便于用户快速、直观地比较官方IEC标准与其前一版之间的所有变更。IEC TS 63042-301:2026是一项技术规范，适用于交流输电系统最高电压超过800 kV的电气设备及其保护和控制系统现场验收试验。电压超过800 kV的电气设备包括以下项目：- 电力变压器；- 断路器；- 气体绝缘开关设备（GIS）；- 气体绝缘输电线路（GIL）；- 避雷器；- 电压互感器和电流互感器；- 并联电抗器；- 串联补偿器；- 绝缘子；- 隔离开关和接地开关；- 高速接地开关（HSES）。本版第二版取消并替代了2018年发布的首版。本版为技术修订版，与前一版相比，主要包括以下重大技术变更：a) 新增子条款，规定现场组装变压器的短路阻抗和负载损耗测量；b) 新增子条款，规定现场组装变压器的空载损耗和电流测量；c) 新增GIL的现场验收试验要求；d) 新增关于保护和控制系统现场验收试验的条款。 [外文原描述]： IEC TS 63042-301:2026 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 TS 63042-301:2026, which is a technical specification, applies to on-site acceptance tests of electrical equipment with the highest voltages of AC transmission system exceeding 800 kV and its protection and control system. The electrical equipment exceeding 800 kV includes the following items: - power transformers; - circuit-breakers; - gas insulated switchgear (GIS); - gas insulated transmission line (GIL); - surge arresters; - voltage and current transformers; - shunt reactors; - series compensators; - insulators; - disconnectors and earthing switches; - high-speed earthing switches (HSES). This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new subclause with measurement of short-circuit impedance and load loss for on-site assembly transformer has been added; b) new subclause with measurement of no-load loss and current for on-site assembly transformer has been added; c) on-site acceptance test requirement for GIL has been added; d) new clause with protection and control system on-site acceptance tests has been added.
