矿山带式输送机变频操作系统设计 摘要 第三次科技革命被称之为电子革命。电子设备运用到社会生活的各个方面。工厂、矿山等重工业生产的产品在利用传统的生产工具的基础之上与现代电子生产设备相结合。变频器是一种数字式变频运转设备及相关的散热技术为一体的高新技术产品。用在链式运转器上能够降低对输送带带强的要求，减少先期投入，可延长运转器使用使用周期。变频器具有明显的节能效应，实现经济运行，变频器工作时，可根据电机的负荷变化，调整电机工作电源电压和周期，达到所需转矩。用变频器对矿井下-845主运传输带运输机变频器机继电操作系统的改造阐述变频器在产品性能、运行周期的功率、及后期正常维护的优越性，希望本文的研究对后期这方面的研究提供一定的可行性文献。 关键词：带式输送机、变频器、改造、干扰 Abstract: drive (mine flameproof and intrinsically safe AC inverter) Rated voltage 660V AC 50Hz, or 1140V asynchronous motor heavy-duty soft start, soft stop and running speed control, starting current, stable starting speed, start time is adjustable, small impact on power, reliable starting performance. Is a digital frequency control devices and related cooling technology as one of the high-tech products. Used in belt conveyor can reduce conveyor belt requirements, reduce upfront investment to extend the conveyor life. Converter with energy-saving effect, economic operation, the inverter operates according to the motor load changes, adjust the motor supply voltage and frequency to achieve the required torque. Explained the transformation of the mine -845 main transport belt conveyor AC motor relay control system with inverter inverter in product performance, the efficiency of the running cycle, and the superiority of the latter part of normal maintenance, and hoped that this paper late provide feasibility Document. Keywords: belt conveyor, the drive, the transformation of interference 目 录 TOC \o 1-3 \h \u  HYPERLINK \l _Toc13575 摘要  PAGEREF _Toc13575 1  HYPERLINK \l _Toc27101 Abstract  PAGEREF _Toc27101 1  HYPERLINK \l _Toc4340 1. 矿山带式输送机变频操作技术及其应用  PAGEREF _Toc4340 3  HYPERLINK \l _Toc2966 2. 矿山带式输送机变频操作系统的主要特点及工作要求  PAGEREF _Toc2966 4  HYPERLINK \l _Toc18924 3.矿山带式输送机变频操作运转方式  PAGEREF _Toc18924 6  HYPERLINK \l _Toc19047 3.1 V/f协调操作  PAGEREF _Toc19047 6  HYPERLINK \l _Toc1010 3.2变量操作  PAGEREF _Toc1010 7  HYPERLINK \l _Toc7697 3.3直接转矩操作  PAGEREF _Toc7697 7  HYPERLINK \l _Toc21599
