10kV母线电容电流治理新模式与实践研究OA

With the development of distribution networks and the extensive application of urban cables,equipment safety issues caused by excessive capacitive current becomes increasingly prominent.To accurately assess capacitive currents and the operational status of arc suppression coils,and to prevent fire accidents in cables due to capacitive currents,a new governance model is proposed:"precise capacitive current detection,functional verification of arc suppression coil controllers,and multi-disciplinary integrated recti-fication and closed-loop management."It analyzes the operating conditions of capacitive current in 88 substations of 110 kV and above.It proposes suggestions for increasing the capacity of arc suppression coils and defect elimination plans.From the planning and feasibility study stage to the operation and maintenance and repair stage,it carries out the entire process of technical supervision and management,clarifying the arc suppression coil and capacitor current treatment plan.It provides a reference for the operation and maintenance of related equipment.
