Design on Avoiding Overriding Trip System of Coal Mine High-voltage Grid
Abstract：The overriding trip accident of high voltage electrical transmission systems in mine is generally caused by some short-circuit faults,which may lead to a wide range of power failure and gas accumulation,threatening the safety of the mine.In this paper,the features of mine grid transmission system were discussed firstly.And then an overriding trip protecting system is designed by deeply investigating on its working principles and characteristics.The system can solve the overriding trip problems effectively and help to ensure the reliability and safety of mine electrical supply system.
