Contact resistance at busbar connections in distribution rooms is a critical factor affecting power system stability and safety. Increased contact resistance may lead to poor current transmission, potentially causing overheating and equipment damage. Key control methods include selecting appropriate contact materials, optimizing contact surface design, implementing proper surface treatments, and conducting regular maintenance inspections. These measures can effectively reduce contact resistance, thereby enhancing the reliability and operational efficiency of power distribution systems. This paper provides a detailed analysis of these control methods, examines their practical effectiveness and implementation challenges, and offers theoretical foundations and technical support for ensuring long-term stable operation of electrical equipment.
