大功率电气柜节能理论研究

Research on Energy Saving Theory for High-Power Electrical Cabinet

由于大功率电气柜散热大,致使室内热负荷也增大,常规解决办法是利用空调维持温度,但节能效果会降低,为此提出一种新模式。在对原系统不作大幅改动的情况下,仅简单增加外部设备便可将电气柜产生的热量直接排出室外。通过对5个典型城市物理模型进行分析,结果显示新的模式经济效益更好,具有普遍适用性和推广性。

The heat dissipation of high-power electrical cabinet is large,resulting in a significant increase in indoor heat load.The conventional method is to use air conditioning to maintain an appropriate indoor temperature.In this paper,a new mode is proposed,in which the heat generated by the electrical cabinet is directly discharged outdoors by adding a simple external system without significant changes to the original equipment.The physical models of the two models are established,and the model is applied to analyze five typical cities.The results show good economic and social benefits of the technology,universal applicability and can be widely popularized.
