3300V供电在综采工作面的应用

介绍了综采工作面在设计电气设备选型及安装过程中，分别采用提高供电电压等级、变极调速等方法减功解决了设备起动对电网的冲击。3300V供电在综采工作面的应用具有较大的推广价值。

Introduced methods of the design in fully mechanixed coal face,the choice and the installation of electric equipment,applied to rise the grade voltage,multispeed asynchronous motor, successfully solve the problem of impulse power network when start equipment.The application of 3 300 V in fully mechanized coal face is possessed of the bigger populized value.
