| titleOfInvention | An improved method for fault detection of mine cables |
| abstract | The invention provides an improved method for fault detection of mine cables, which belongs to the technical field of cable fault detection. Including the following steps: Step 1, replace the sensor of the current measuring device, change the original open-loop or Rogowski coil of the current measuring device to a microcrystalline iron core current transformer, and use the open-loop or Rogowski coil in the existing fault detection device to measure the cable current. Detection, the error between the detected value and the actual value is high, resulting in inaccurate judgment of the fault; Step 2, the power supply method, the power supply of the current measuring device adopts the dual power supply method of combining lithium battery power supply and online power supply; Step 3 , adopts a stable hardware structure, and the controller of the current measuring device adopts watchdog hardware, watchdog software and hardware structure for operation; the improved fault detection device can realize ultra-high precision and ultra-high accuracy in judging faults , to improve the efficiency of short-circuit fault and ground fault detection. |
