随着重介选煤技术及集中控制技术的发展,集控系统及PLC仪器仪表在选煤厂的应用也越来广泛,集控系统非常有利于调度指挥,是选煤厂电气控制的组成核心具有很强的推广性。但有些电气设备受干扰的问题也变得越来越突出,有的干扰已经严重到影响电气设备的正常工作。从电源类的干扰、射频类的干扰以及机械设备的干扰等方面对电气系统产生干扰的因素进行分析,并提出设备的维修措施,为选煤厂的正常运行提供了保证,同时也指出了节能降耗的具体办法,为各选煤厂节能降耗,提高经济效益提供了理论依据。
With the development of heavy medium coal preparation technology and centralized control technology, the application of centralized control system and PLC instrumentation in coal preparation plant is also more and more extensive. The centralized control system is very conducive to dispatching command and control. It is the core of the electrical control of coal preparation plant Strong promotion. However, some electrical equipment is also subject to interference problems have become more prominent, and some interference has been seriously affected the normal operation of electrical equipment. From the interference of power class, the interference of radio frequency and the interference of machinery and equipment, the disruptive factors of the electrical system are analyzed. The maintenance measures of the equipment are put forward to ensure the normal operation of the coal preparation plant. At the same time, the energy saving Specific measures for reducing consumption, for the coal preparation plant energy saving, improve economic efficiency provides a theoretical basis.
