| Abstract: | The harmonic wave in the power source of the electric drive drilling rig will produce interference on the PLC, and causes drilling operation stopped. An anti-jamming device with filter circuit is developed. The power source from the power network is isolated and stepped down and multistage filtered, the noise is filtered, and wave contour is improved, and the high-quality sine wave power source is obtained at last. Field use proves the anti-jamming device having good wave filtering effect and ensuing control system of the drilling rig operating without troubles. |
