带电作业. 安装在底盘上的绝缘天线设备

[中文适用范围]： 本文件适用于安装在底盘上的绝缘架空设备，用于在 45 Hz 至 65 Hz 范围内和 1 500 V DC 范围内标称电压高于 1 000V rms AC 的电气装置带电作业。高空作业装置的主要用途是人员的工作定位。可以安装其他设备，例如起重臂，以帮助操作员执行工作。本文件还包括影响带电作业用绝缘架空设备性能的底盘部件的要求和测试。当安装在底盘上时，绝缘空中装置成为移动式升降工作平台（MEWP）的组成部分。 ISO 16368 中包含了由此产生的 MEWP 的补充要求。 注 1：在欧洲，通常使用 EN 280 而不是 ISO 16368 作为补充要求的参考。根据本文件设计和制造的产品有助于用户的安全，前提是由技术人员按照安全工作方法和使用说明使用。注 2：任何与 ISO 16368 相冲突或旨在补充 ISO 16368 的要求均在此描述。本文件不包括径向动臂（挖掘机）井架。 [外文原描述]： IEC 61057:2017 is applicable to insulating aerial devices for mounting on a chassis, to be used for live working on electrical installations at nominal voltages above 1 000V r.m.s. AC in the range 45 Hz to 65 Hz and 1 500V DC. This second edition cancels and replaces the first edition published in 1991 and IEC TS 61813:2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) general review of the requirements and test provisions; b) preparation of the elements of evaluation of defects, and general application of IEC 61318:2007; c) distinguishes between tests for hollow booms and those for foam filled booms; d) references ISO 16368 for particular mechanical tests; e) further information on vacuum protection and leakage current monitoring and a mandatory requirement that aerial devices for bare hand work be fitted with a permanently installed lower test electrode system; f) controls of high electrical resistance; g) reference to SAE for insulating hydraulic hoses; h) inclusion of IEC TS 61813 for care, maintenance and in-service testing of aerial devices with insulating booms.
