带式输送机用双功率高效节能型隔爆电动机及控制装置的研制

摘要

针对煤矿井下的带式输送机要求高起动转矩和时变负载运行的特点,运用复合连接新技术,＂去匝＂新技术和双向切换控制技术,设计研发了一种双功率隔爆三相异步电动机及控制装置。它可根据输送机负载的变化自动调节电动机功率,达到节能运行,以提高功率因数和运行效率。该电动机及控制装置经煤矿井下工业性试验运行,取得了较好的效果。%The belt conveyor for coal mine requires high starting torque and time-varying performance of load operation.Uses composite junction new technology,＂demagnetizing turn＂ new technology and two-way switch control technology,designs and develop one dual-power flame-proof three phase asynchronous motor and its control device.This device can automatically adjust motor power according to conveyor belt load variability,which achieves energy-saving operation,improves motor power coefficient and operation efficiency.This motor and its control device gains good results by industrial testing operation at underground coal mine.
