Description
technical field [0001] The invention relates to the technical field of low-voltage no-power compensating devices, in particular to a low-voltage no-power compensating device. Background technique [0002] The role of the low-voltage reactive power compensation device in the electronic power supply system is to improve the power factor of the power grid, reduce the loss of power supply transformers and transmission lines, improve the power supply efficiency, and improve the power supply environment. Therefore, the reactive power compensation device is used in the power supply system. In an indispensable and very important position, a reasonable selection of compensation devices can minimize the loss of the network and improve the quality of the power grid. On the contrary, improper selection or use may cause power supply system, voltage fluctuation, harmonic wave increase and many other factors. [0003] The current static non-power compensation generally uses thyristor swit...
