超高层公共建筑电气供配电的设计研究

Design and Research of Electric Power Supply and Distribution for Super High-rise Public Buildings

针对建筑电气供配电能源浪费、负荷较低,影响超高层公共建筑用电需求的问题,研究了超高层公共建筑电气供配电的设计这一课题。搭接公共建筑电气主接线,将所有的进、出线回路连接在母线上,确保供配电可靠性与灵活性。建立超高层公共建筑电气供配电系统,对变压器、供电电源、配电系统等方面进行设计,满足电气供配电需求。设置公共建筑电气供配电防雷及过电压保护,将接闪器、引下线、接地极、一级电涌保护器等电位联接,确保超高层公共建筑的用电安全。采用实例分析的形式,验证了该电气供配电形式更符合建筑需求,其在负荷容量、供配电系统电压、短路电流、保护设备动作时间和能源效率方面均表现良好,其能够应用于实际生活中。

In view of the problems of energy waste and low load of building electric power supply and distribution,which affect the electricity demand of super high-rise public buildings,the design of electric high-rise public buildings,design transformer,power supply,distribution system,etc.,to meet the needs of electric power supply and distribution.Set up lightning protection and overvoltage protection for electric power supply and distribution of public buildings,and connect potential such as flash adapter,lead down line,ground pole and first-level surge protector to ensure the safety of electric consumption of super high-rise public buildings.Through the form of example analysis,it is verified that the electric power supply and distribution form is more in line with the building demand,and it has good performance in load capacity,power supply and distribution system voltage,short circuit current,operation time of protection equipment and energy efficiency,which can be applied to real life.
