矿山按产品类型可分为煤矿、金属矿和非金属等;按采掘方式可分为露天开采矿山和地下开采矿山两大类。本文主要介绍变频调速器在金属矿山中的应用的现状和应用前景,对煤矿亦有参考价值,因为露天煤矿和露天金属矿开采方式和生产设备基本相同,地下矿山除需要考虑设备的防爆问题外,大部分生产设备也与金属矿大同小异。露天采矿和地下采矿所用的生产设备有很大不同。露天矿山是以大型设备为主要特点,要求优良的电气传动系统,以保证这些大型设备的高效率运行。露天矿山的这些大型设备包括用于穿孔的牙轮钻机,用于装载矿、岩石的电铲(挖掘机),用于运输矿、岩石的大型汽车等。它们都要求电气传动系统具有良好的调速性能,目前这些大型设备大多采用直流调速传动系统。
According to the types of mines can be divided into coal mines, metal mines and non-metallic, etc .; by mining methods can be divided into open pit mining and underground mining two major categories. This article mainly introduces the current situation and application prospect of the application of the frequency converter in the metal mine and also has the reference value to the coal mine. Because the open-pit and open-pit metal mining methods and production equipment are basically the same, the underground mine need to consider the explosion-proof of the equipment Most of the production equipment is also similar to metalloids. The equipment used for open pit mining and underground mining is vastly different. Open-pit mines are large-scale equipment as the main features, require excellent electrical transmission system to ensure the efficient operation of these large-scale equipment. These large-scale equipment in open pit mines include a roller cone rig for piercing, a shovel (excavator) for loading mines and rocks, a large car for transporting mines and rocks, and the like. They all require the electric transmission system has a good speed performance, most of these large devices currently use DC speed control drive system.
