交流电压1000V以上的绝缘套管

[中文适用范围]： 本国际标准规定了绝缘套管的特性和试验。本标准适用于第 3 章中规定的套管，用于三相交流系统的电气设备、机械、变压器、开关设备和装置，设备最高电压超过 1 000 V，电源频率为 15 Hz高达 60 Hz（含）。根据买方和供应商之间的特别协议，本标准可部分或全部适用于以下各项： ~ 用于三相系统以外的套管； ~ 高压直流系统套管； ~ 用于测试变压器的套管； ~ 电容器套管。本标准中变压器套管的特殊要求和试验也适用于电抗器套管。本标准适用于单独制造和销售的套管。作为设备一部分且无法根据本标准进行测试的套管应使用其构成部分的设备进行测试。 [外文原描述]： IEC 60137:2008 gives the characteristics and tests for insulated bushings intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having highest voltage for equipment above 1 000 V and power frequencies of 15 Hz up to and including 60 Hz. Special requirements and tests for transformer bushings in this standard apply also to reactor bushings. This edition includes the following significant technical changes with respect to the previous edition: - Long duration power-frequency for transformer bushings; - Special requirements for type and acceptance tests applicable to transformer and GIS bushings; - Specific insulation levels for bushings fitted to transformers and GIS; - According to IEC Guide 111, clauses relating to safety and the environment have been added; and - The altitude correctino procedure has been revised (> 1 000 m).
