The Motor Control Center (MCC) at the well site supplies power and controls low-voltage AC motors, lighting systems, living facilities, and other AC equipment.
MCC， It refers to the control device for the electric drive of drilling rig auxiliary machinery, which realizes the centralized and remote control operation of equipment, solves the difficulties caused by the dispersion of electrical equipment in installation, maintenance, inspection and management, and is conducive to the overall explosion prevention of the control device.
The above equipment and its supporting explosion-proof circuit can meet the working parameters, performance, and drilling process requirements of various drilling rigs, and also have explosion-proof, waterproof, fireproof, anti-corrosion, and impact resistant properties, which can adapt to the harsh conditions of outdoor operations in oil fields.
