煤矿设备应用高压变频调速技术研究实践

Research and Practice of High Voltage Frequency Conversion Speed Regulation Technology for Coal Mine Equipment

地处山东省济宁市范围内的煤矿,在矿井主通风机同步电动机高压变频调速系统、高压变频提升机电控的安全回路、热电厂厂用电动机高压变频器节能改造、高压变频技术在热电厂给水泵的应用方面解决了一些应用问题,有效地保障了安全、高效生产。

Located in Jining City, Shandong Province, the coal mine urgently needs to solve the problems in the applicati on of high-voltage frequency conv ersion tech no logy to the feed pump of the thermal power plant, such as the high-voltage frequency conversi on speed regulation system of synchro nous motor of the main fan, the safety circuit of the electric control of the high-voltage frequency conversion hoist, the energy-saving transformation of the high-voltage frequency converter of the auxiliary motor of the thermal power plant, and the effective guarantee of safe and efficient production.
