摘　　要：随着通信行业的飞速发展,人们对于通信业务的需求也在不断增加。为了更好地满足人们的需求,通信机楼也在不断增加负荷。在此情况下,通信设备的稳定运行需要稳定、高效、可靠的通信供配电系统作为支撑。由于240 V高压直流电源系统具有高可靠性、维护简易、转换效率高等优势,越来越多的数据中心、通信机楼选择使用该系统来替换传统的交流不间断电源(Uninterruptible Power System,UPS)系统。240 V高压直流(High Voltage Direct Current,HVDC)电源系统的使用也给通信机楼的动力维护人员带来了挑战,结合现场的实际维护案例,对240 V高压直流供电系统使用过程中可能出现的绝缘冲突问题进行探讨。With the rapid development of the communication industry,people's demands for communication services are also increasing.In order to better meet people's needs,the communication building is also increasing the load.In this case,the stable operation of communication equipment requires a stable,efficient and reliable communication power supply and distribution system as a support.Due to the advantages of high reliability,easy maintenance and high conversion efficiency of the 240 V High Voltage Direct Current(HVDC)power supply system,more and more data centers and communication buildings choose to use this system to replace the traditional AC Uninterruptible Power System(UPS)system.The use of 240 V HVDC power supply system also brings challenges to the power maintenance personnel in the communication building.Combined with the actual maintenance cases on site,the problem of insulation conflict that may occur during the use of 240 V HVDC power supply system is discussed.
