近年来 ,随着技术的进步 ,特别是功率器件的更新换代 ,新型电磁材料的不断使用 ,功率变换技术的不断进步 ,控制方法的不断改进 ,以及相关学科的不断融合 ,通信电源在系统的可靠性和稳定性、电磁兼容性、消除网侧电流谐波、提高电能利用率、降低损耗、提高系统的动态性能等方面都取得了长足的进步。通信电源正向高频化、高功率密度、高功率因数、高效率、高可靠性和高智能化方向发展。通信电源作为通信系统的“心脏” ,其重要性已越来越被各级领导和运行维护部门所认识 ,而且对其相关设备和技术提出了更高的要求。为了能有效地宣传通信电源技术的发展 ,交流通信电源设备的应用及运营维护经验 ,促进通信服务质量的进一步提高 ,我刊特别策划了本期专题。在本专题的策划过程中 ,信息产业部邮电工业产品质量监督检验中心的熊兰英主任、中国电信集团公司设备维护管理处的张清贵副处长和信息产业部邮电设计院电源处的王殿魁副总工给予了我刊悉心的指导和帮助 ;北京、上海、广东、黑龙江、山东和浙江等省市电源主管给予了大力支持 ,在他们的精心组织下 ,向我刊推荐了一批很有实用价值的运维经验类文章 ;安圣电气、中兴通讯、杭州南都、武汉洲际、上海潘登、北京通力环和施威特克等公司对本专辑的出版也给予了支?
In recent years, with the progress of technology, especially the replacement of power devices, the constant use of new electromagnetic materials, the continuous improvement of power conversion technology, the continuous improvement of control methods and the continuous integration of relevant disciplines, the reliability of communication power in the system It has made great progress in the aspects of stability and stability, electromagnetic compatibility, elimination of current harmonics on the grid side, improvement of power utilization, reduction of loss and improvement of dynamic performance of the system. Communication power is positive high frequency, high power density, high power factor, high efficiency, high reliability and high intelligence direction. As the “heart” of communication system, communication power has become more and more important by the leaders and operation and maintenance departments at all levels, and puts forward higher requirements on the related equipments and technologies. In order to effectively promote the development of communication power technology, the application of communication and communication power equipment and operation and maintenance experience, and to promote the further improvement of the quality of communication services, this issue has been specially planned by our journal. During the planning of this topic, Xiong Lanying, director of the post and telecommunications industry product quality supervision and inspection center of the Ministry of Information Industry, Zhang Qinggui, deputy director of equipment maintenance and management office of China Telecom Corporation, and Wang Dian-kui, deputy chief engineer of power supply department of post and telecommunications design institute of Ministry of Information Industry I wrote my heart’s guidance and help; Beijing, Shanghai, Guangdong, Heilongjiang, Shandong and Zhejiang provinces and cities such as the power director gave strong support, in their careful organization, to my magazine recommended a number of very useful value of the transport Dimensional experience articles; Ansheng Electric, ZTE, Hangzhou Nandu, Wuhan Intercontinental, Shanghai Pan Deng, Beijing KONE and Schweitzer and other companies on the album’s publication also gave support?
