套管.抗地震能力

[中文适用范围]： IEC TS 61463 是一项技术规范，适用于安装在变压器、其他设备或建筑物上的最高电压超过 52 kV（或共振频率位于地震反应谱内）的交流和直流套管。对于最高电压小于或等于52 kV（或谐振频率位于地震反应谱之外）的套管，由于其特性，只要施工实践和抗震施工实践符合国家标准，则不采用抗震资格。艺术。本文件提出了可接受的地震鉴定方法和要求，以证明套管可以在地震期间和地震后保持其机械性能、绝缘和承载电流。套管的抗震鉴定仅根据要求进行。 [外文原描述]： IEC TS 61463:2016(E), which is a Technical Specification, is applicable to alternating current and direct current bushings for highest voltages above 52 kV (or with resonance frequencies placed inside the seismic response spectrum), mounted on transformers, other apparatus or buildings. For bushings with highest voltages less than or equal to 52 kV (or with resonance frequencies placed outside from the seismic response spectrum), due to their characteristics, seismic qualification is not used as far as construction practice and seismic construction practice comply with the state of the art. This document presents acceptable seismic qualification methods and requirements to demonstrate that a bushing can maintain its mechanical properties, insulate and carry current during and after an earthquake. The seismic qualification of a bushing is only performed upon request.
