关于《交通建筑电气设计规范》3.4.4条的争议及改进建议

Disputes and Improvement Suggestions Regarding Article 3.4.4 of the Code for Electrical Design of Transportation Buildings

飞机中频电源、地面空调设备功率很大,其负荷计算的准确性对于变压器设备选型和供电方案的确定都有很大的影响。目前大部分支线机场只在近机位廊桥设置桥载设备,总设备数量为5台以下,这种情况下《交通建筑电气设计规范》3.4.4条中的需要系数不能直接使用。本文对于规范的该条文提出自己的理解看法,解释原因,并提出新的计算方法,供大家参考、讨论。

The power of aircraft mid frequency power supply and ground air conditioning equipment is very high,and the accuracy of their load calculation has a great impact on the selection of transformer equipment and the determination of power supply schemes.Considering that many branch airports currently only have bridge mounted equipment installed near the aircraft stands,with a total number of less than 5 units.For this situation,the demand coefficient in Article 3.4.4 of the Code for Electrical Design of Transportation Buildings cannot be directly used.This article presents its own understanding of the normative provision,explains the reasons,and proposes new calculation methods for everyone's reference and discussion.
