通信枢纽楼低压配电系统的设计初探

以某通信运营商通信枢纽楼低压配电系统改造项目为例，详细介绍了通信负荷的分类，包括一般负荷以及保障负荷，并说明了近期及远期负荷的估算方法，最后针对估算出的枢纽楼近远期的通信负荷，提出了合理的低压配电改造方案，解决了枢纽楼存在的问题。同时详细介绍了低压配电设备的使用及选型，其中包括低压配电柜、低压断路器、浪涌保护器，无功补偿装置等设备，为方案的具体实施提供了可靠依据。

Design of Low-Voltage Distribution System for Telecommunication Hub Building

With the distribution system reconstruction project of certain communications operator＇ s telecommunication hub building as an example, the classifications of communication load are described, including ordinary load and guaranteed load, and the methods to estimate the short-and long-term load expounded. Then according to the load estimation, reasonable reconstruction project for low-voltage distribution is proposed, thus to solve the problems in the construction of hub building. Meanwhile, the use and selection of low-voltage distribution devices is discussed, these devices include low-voltage distribution boards, low-voltage circuit breaker, surge protector, reactive power compensation device and so on, thus providing a reliable basis for the project implementation.
