ICT数据中心和电信中心中压输入和高达±400 VDC输出电力系统的电气安全和防雷保护 |
ITU-T K.151建议书提供了中压电力电子转换器系统的电气安全和防雷要求指南,这些系统具有额定系统电压为1 000 V AC至36 kV AC的中压输入和额定电压至±400 V DC的低压输出,用在信息通信技术(ICT)数据中心、电信中心或其他应用环境中。随着大数据和云计算技术的发展,数据中心和电信中心的数量和总容量以及ICT设备的功率密度正在迅速增加。在这种情况下,发现在许多现有的数据中心和电信中心中,传统的配电设备和电力系统具有低能效、高能耗、高维护难度和高成本的缺点。为了解决这些问题,有必要开发一种新的整体电力系统结构,它可以直接由中压供电,并基于电力电子转换。从电气安全和防雷的角度来看,由传统低压交流电(AC)供电的数据中心和电信中心与由中压供电的数据中心和电信中心之间有很多的不同。本建议书主要关注电气绝缘、局部放电、电气安全、阻抗和雷电浪涌保护。 |
