高低压变频调速技术在煤矿行业已得到广泛应用,尤其在节约电能、自动化控制等方面体现了它的优越性能。河南神火煤电股份有限公司刘河煤矿、新庄煤矿在用的空气压缩机(以下简称空压机),通过高低压变频调速和自动化控制技术的应用[1],使空压机启停更加合理,达到了节能降耗、安全运行的目的。1高压变频自动化控制技术的应用1.1高压变频器的组成及原理该公司地面空压机配电系统均为6kV,变频系统采用每相六单元串联,每个功率单元输出有效交流电压值为577V,相电压为3464V,线电压为6000V。
High and low voltage frequency control technology in the coal industry has been widely used, especially in saving electricity, automation and control reflects its superior performance. Henan Shenhuo Coal Co., Ltd. Liuhe Coal Mine, Xinzhuang Coal Mine in the use of air compressors (hereinafter referred to as air compressor), through the application of high and low voltage frequency control and automation technology [1], start and stop more air compressor Reasonable, reached the purpose of energy saving, safe operation. A high-voltage inverter automation control technology 1.1 The composition and principle of high-voltage inverter The company ground air compressor distribution system are 6kV, frequency conversion system uses six units per phase in series, each power unit output valid AC voltage value of 577V, The phase voltage is 3464V and the line voltage is 6000V.
