矿井通风系统数字化变频技术改造方案设计

摘要

PLC and inverter are used to control the energy consumption of the system, which greatly reduces the energy consumption. In addition, the system undertakes switching between constant frequency and variable frequency, widens the speeding range, reduces noises and improves working environments, as well as prolongs the service life, increases the economic benefit and productive efficiency of the mine.%系统采用PLC和变频器对风机进行节能控制,大大降低了能源消耗,并且该系统可进行工频/变频切换,调速范围广,噪声小,可改善工作环境,延长风机的使用寿命,提高经济效益和生产效率.
