标准范围

新的！IEC 60137:2017作为IEC 60137:2017 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60137:2017规定了绝缘套管的特性和测试。本标准适用于第3条中定义的套管，用于电气设备、机械、变压器、开关设备和三相交流系统的装置，设备的最高电压高于1000 V，电源频率为15 Hz至60 Hz（包括60 Hz）。根据买方和供应商之间的特别协议，本标准可以部分或全部适用于以下情况:-用于三相系统以外的系统的衬套；-高压直流系统用套管；-用于测试变压器的套管；-电容器用衬套。本标准中对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衬套。作为设备的一部分且不能根据本标准进行测试的衬套应与作为其一部分的设备一起进行测试。与上一版相比，此版本包括以下重大技术变更:-已推出树脂浸渍合成(RIS)衬套。-引入了Um≤1.1 kV、Um=1100 kV和Um=1200 kV的套管。-根据第3.4条，包括液体绝缘衬套的温升试验。-引入干式雷电脉冲测试，作为Um>72.5 kV的所有变压器套管的常规测试。-修订了海拔修正程序（>1 000米）。-包括关于极快瞬态（VFT）现象及其对衬套影响的解释。

NEW!IEC 60137:2017 is available as IEC 60137:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60137:2017 specifies the characteristics and tests for insulated bushings.
This standard is applicable to bushings, as defined in Clause 3, 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.
Subject to special agreement between purchaser and supplier, this standard may be applied, in part or as a whole, to the following:
- bushings used in other than three-phase systems;
- bushings for high-voltage direct current systems;
- bushings for testing transformers;
- bushings for capacitors.
Special requirements and tests for transformer bushings in this standard apply also to reactor bushings.
This standard is applicable to bushings made and sold separately. Bushings which are a part of an apparatus and which cannot be tested according to this standard should be tested with the apparatus of which they form part. This edition includes the following significant technical changes with respect to the previous edition:
- Resin-impregnated synthetic (RIS) bushings has been introduced.
- Bushings with Um ≤ 1,1 kV, Um = 1100 kV and Um = 1200 kV have been introduced.
- Temperature rise testing has been included for liquid-insulated bushings according to clause to 3.4.
- Introducing dry lightning impulse testing as a routine test for all transformer bushings with Um > 72,5 kV.
- The altitude correction procedure has been revised ( > 1 000 m).
- An explanation about Very Fast Transient (VFT) phenomenon and its impact on bushings has been included.
