3、2400A时温度达70度,可能环境温度较高或散热较差。举例:t2铜排允许通过的电流为2000A,铜排温升不得超过50℃。铜排温升要怎么控——铜排允许规定,铜排温度不能超过45℃。2. 根据际电气安全委员会(IEC)的规定,且在额定电流运行情况下,不得时间超过60℃。4. 根据家物资《低压电
铜排温度不能超过70度按GB50060-92《3~110kV高压配电装置设计规范》11条的规定:导体的正常最高工作温度不超过70度,对镀(搪)锡的母排允许达到3 、2 4 00A shi wen du da 7 0du ,ke neng huan jing wen du jiao gao huo san re jiao cha 。ju li :t 2 tong pai yun xu tong guo de dian liu wei 2 000A ,tong pai wen sheng bu de chao guo 5 0℃ 。tong pai wen sheng yao zen me kong zhi ——tong pai yun xu "

各位,关于铜排的温度和温升,有两点不太明白1,有的资料说,环境温度35 最高运行温度就是105度。那么,环境温度10度,允许温升还是70度吗?环境在验证铜排载流量试验(即温升试验)时是基于: 环境平均温度35℃,铜排的最高运行温度是105℃,铜排的温升是70K。福州大学张冠生教授的《电器学》和GB/T25840-2010 规定电气设备部件(特别是接线端子)允许温升的导则等
