摘要: 分析了露天采煤机用电气设备散热方式的优缺点;根据露天采煤机的实际工况,采用滤筒除尘器对露天采煤机的变频调速装置、降压变压器等电气设备进行强迫通风散热,利用原有的除尘通风设备给操作室通风和加热。滤筒除尘通风装置在露天采煤机中的应用,不仅保证了露天采煤机的可靠运行,延长了电气设备各元器件的使用寿命,而且使电气设备散发的热量得到了循环利用,达到了节能的效果。Abstract: Advantages and disadvantages of heat-dissipating method of electrical equipments for open-pit shearer were analyzed. According to actual condition of open-pit shearer, filter cartridge deduster was used to ventilate and dissipate heat for frequency-conversion speed-regulation device and step-down transforms of open-pit shearer, and the original dedusting ventilation equipment was used to ventilate and heat operating room. The application of filter cartridge deduster and ventilation equipment in the open-pit shearer, not only ensures reliable operation of open-pit shearer and prolongs service life of components of electrical equipment, but also make heat distributed by electrical equipment recycle and reuse and achieve effect of energy saving.
