Description
technical field [0001] The invention relates to a simulation device for training in the electric power industry, in particular to a low-voltage capacitor cabinet training device used for teaching, training and competition assessment. Background technique [0002] Low-voltage power distribution lines often use low-voltage capacitor cabinets for reactive power compensation. Reactive power compensation can improve the power factor of the power grid, reduce the loss of power supply transformers and transmission lines, improve power supply efficiency, and improve the power supply environment. Therefore, the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can minimize the loss of the network and improve the quality of the power grid. [0003] The low-voltage capacitor cabinet includes the main line and multiple sets of compensation capacitors. By switching in or removing...
