特高压户内直流场通风空调系统对比分析

The Comparative Study of Ventilation and Air-conditioning System in UHV Indoor DC Filed

户内直流场常用的环控方式有通风与空调两种方案。以某1 100 kV特高压户内直流场为例,结合实际情况进行了通风与空调的方案设计。利用Fluent流体模拟软件,对场内温度环境作预测仿真,对比分析了两种方案的优劣性。结果表明,通风与空调两种方案均能达到室内温控要求,但空调方案更有利于设备的安全运行。该研究结果可为大空间户内直流场的降温方案择优提供借鉴。

The ventilation and air-conditioning scheme are the common environment control methods in indoor DC field. This paper, which is on the basis of a project of 1 100 kV UHV indoor DC filed, designs the ventilation and air-conditioning system according to the actual situation; Using Fluent numerical simulation software to forecast the temperature filed, the comparison and analysis between the two schemes are carried out. The results show that both schemes can meet the indoor temperature requirement, but the air--conditioning scheme provides a safer operation environment for the equipment, which offer the reference for the optimal design of cooling scheme for large space indoor DC filed.
