Control of Self-provided Power Supply Return Power Transmission in Low-voltage Bench Area

In order to prevent the occurrence of the customer's self-provided power supply, for the low-voltage self-supplied power supply in the power supply station, we developed and promoted the application of a low-voltage power supply dual power control box. In the low-voltage customer's self-supplied generator, photovoltaic power generation, and double-circuit power supply, we installed a self-provided dual power control box to control the dual power supply from the source.
