Product Overview\n\nThe electric control system of electric drilling rig is a drive control system for electric drilling rigs independently developed and manufactured by our company by absorbing and adopting advanced domestic and international electric control technologies of drilling rigs and combining with a large number of on-site application experiences of drilling rigs over the years. This system is divided into DC electric control system and AC variable frequency electric control system according to different electric drilling rigs. The DC electric control system mainly includes generator set control unit, DC drive control unit (SCR), motor centralized control center (MCC), integrated control unit (PLC), etc. The AC variable frequency electric control system mainly includes generator set control unit, AC variable frequency control unit (VFD), motor centralized control center (MCC), integrated control unit (PLC), etc. The generator set control, motor set control operation, output characteristics, protection functions, etc. of the electric control system of the electric drilling rig can all meet the working parameters, performance and drilling process requirements of the drilling rig.\n\u003C\u002Fp>\u003Cp>\u003Cimg alt=\"Electric Control System Of Electric Drilling Rig\" src=\"\u002Fuploads\u002F1\u002F2026\u002F10\u002Fead72ea63e564c2098cf63fc913df8d4.jpg\"\u002F>\u003C\u002Fp>\nII.
