Core Viewpoint - The article discusses the significant energy losses associated with reactors in power systems and emphasizes the importance of addressing these losses to reduce electricity costs [1]. Group 1: Energy Loss Sources - Energy losses in reactors primarily stem from two sources: winding losses and core losses. Winding losses occur due to the resistance in the wire when current passes through, which is proportional to the square of the current and the resistance of the winding [3]. - Core losses arise from the silicon steel sheets used in the reactor's core, which experience hysteresis and eddy current losses in an alternating magnetic field. The quality, thickness, and processing of these silicon steel sheets significantly influence core losses [3]. Group 2: Strategies for Reducing Energy Loss - To reduce energy losses, it is crucial to select the appropriate rated current and reactance based on actual system parameters and operational requirements, avoiding prolonged overload conditions to minimize winding losses [3]. - Utilizing high-quality silicon steel sheets for core construction can significantly reduce hysteresis and eddy current losses, thereby decreasing core losses [3]. - Optimizing the winding structure by selecting suitable winding forms and wire cross-sectional areas can lower winding resistance while maintaining reactor performance, further reducing winding losses [3]. Group 3: Maintenance and Operational Measures - Regular inspection and maintenance of reactors are essential to ensure optimal operating conditions, such as cleaning dust and dirt from the reactor surface and keeping heat dissipation channels clear to lower winding temperatures and associated losses [5]. - Adjusting the operational mode of reactors to avoid prolonged no-load conditions is important, as even in no-load situations, core losses can still occur [5]. - The energy-saving and loss-reduction efforts for reactors require a comprehensive approach, integrating various measures to enhance efficiency in practical applications [5].
