Design and Application of Long Distance Power Supply Scheme for Coal Mine Driving Face
In order to solve the problems of large load voltage drop and poor reliable operation ability of driving equipment in long distance power supply of coal mine underground driving face,a long distance power supply scheme based on automatic power supply voltage regulation device is proposed.AC/DC,DC/AC and series compensation principle are used to dynamically adjust the load terminal voltage according to the power supply distance to make it meet the minimum voltage requirement for reliable operation of driving equipment.Finally,the test data of A and B driving face in a coal mine are analyzed to verify the correctness and effectiveness of the proposed electrical scheme.The application results show that the long distance power supply scheme can extend the power supply distance of the driving face equipment,raise the load end voltage,and ensure the safe,efficient and stable production of the driving face.
