国际与IEC62271的区别
虎跟什么相冲本标准根据IEC 62271-200:2003《额定电压1 kV 以上52 kV 及以下交流金属封闭开关设备和控制设备》(第一版、即IEC 60298的第四版)的内容对GB 3906-1991《3~35 kV 交流金属封闭开关设备》进行全面修订。本标准与IEC 62271-200 的一致性程度为修改,其主要差异如下:
The standard GB 3906-1991《3Kv~35 kV AC metal enclod switchgear》was revid ba on IEC 62271-200:2003《AC metal enclod switchgear and controlgear for rated voltage above 1kV and up to and including 52kV》.the differences as follows:
——按GB/T 1.1-2000的规定,对标准的语言表述和格式作了修改;
---According to GB/T 1.1-2000 regulations, revid linguistic expression and format of standard .
大年初一作文——适用的电压范围,由1 kV 以上、52 kV 及以下改为3.6 kV~40.5 kV,并按照GB/T 11022(或GB 156)的规定修改其中与额定电压及其系列值相关的内容;
--- Applicable voltage range change above 1kV、up to and including 52kV to 3.6kV ~40.5 kV, According to GB/T 11022 (GB 156) regulations, revid the content of which is
related with the rated and ries voltage values.
鲁迅的作品——根据我国的电网实际,适用的频率范围由60 Hz 及以下改为50 Hz 及以下,并删除了与60Hz相关的内容;
--- According to the actu al conditions of China’s power grid, applicable frequency range change the up to and including 60 Hz to the up to and including 50 Hz, delete the
content of which is related with 60 Hz.

一一删除了国际标准的前言,增加了本标准的前言;
--- Delete the foreword of IEC 62271-200:2003, add the foreword of GB 3906-1991
——删除了5.10的表 1 中的“说明书”一项,该内容对我国不适用;
--- Delete “manual” on 5.10 Table 1, the content does not apply to China.评价鲁迅先生
路远迢迢—一删除了5.104的注 1 及其内容,该内容对国家标准不适用。相应的注2 改为注;
走读申请书
--- Delete “5.104 Note 1 and its conten t s ”, the con tent does not apply to China
standard. change Note 2 to Note 1.
——联锁方面增加了下述内容:接地开关不论任何情况都应与隔离开关联锁,优先采用机械联锁(本版的5.11中的部分内容):
--- Add the content of interlocking: the earthing switch must interlock with the isolating switch under any conditions. (GB 3906-1991 5.11)
一一根据我国的具体实际,增加了型式试验周期和型式试验报告有效期的要求(本版的6.1);
--- According to the actual conditions of China’s power grid, add the requirements of type test cycle and type test report’s validity period (GB 3906-1991 6.1)
—一将“湿试验程序”由“不适用”改为“按GB/T 11022的6.2.2的规定”(本版的6.2.2) ;
--- Humidity test procedure change “ not applicable” to “follow GB/T 11022 6.2.2 regulations” (GB 3906-1991 6.2.2)
——出厂试验中增加了“出厂试验报告应随产品一起出厂”的规定(本版的第7章);
--- Add “ship products with test report “ regulations on finally test (GB 3906-1991 7)
――根据我国的具体实际,在强制性型式试验、出厂试验的机械操作试验中增加了“机械特性测量”试验(本版的6.102、7.102)。还在适用时的强制性型式试验和出厂试
验中分别增加了“充气隔室的气体状态测量”项目(本版的6.103、7.103):
According to the actual conditions of China’s power grid, add “the mechanical
characteristics measure ment” test on compulsory type test and the mechanical operation
of finally test (GB 3906-1991 6.103 7.103).add “inflatable compartment gas state
measurement” on compulsory type test and finally test when applicable.
――为了方便使用,将IEC 60932:1988《用于严酷气候条件下的1 kV~72.5 kV 交流金属封闭开关设备和控制设备的附加要求》的内容作为附录 C 列入本标准,同时
将适用电压范围由1 kV~72.5 kV 改为3.6 kV~40.5 kV。另考虑到我国的具体环境
状况,还在C.4.3的2类设计的注3中增加了2类设计的爬电比距的推荐值;
---For easy to u ,the IEC 60932:1988《Additional requirements for 1kV ~72.5kV AC metal enclod switchgear and controller ud in harsh climatic conditions》content as Appendix C of GB 3906-1991, Applicable voltage range change 1 kV~72.5 kV to 3.6 kV~40.5 kV. According to the actual conditions of China’s power grid, add recommended values of class 2 design specific creepage distance on the note 3 of C.4.3 class 2 design
――删除了“参考资料”中的IEC 60724:2000 《1 kV 和3 kV 电缆的短路温度限值》,增加了相关内容的附录D;
---Delete IEC 60724:2000《1 kV 和3 kV cable short circuit temperature limit value》, add appendix D of the related content.
一一由于本标准的 5.4和 6.10引用的对应内容尚未包含在国标GB/T 11022-1999 (eqv
IEC60694:1996)中,本标准直接引用IEC 60694:2002的5.4和6.10,同时将IEC 60694:
