Photovoltaic and wind power box-type step-up stations feature reasonable and compact system layout, including three parts: low-voltage incoming cabinet, transformer, and high-voltage outgoing cabinet, independently installed in three compartments, arranged in "目" or "L" shape, with complete functions and convenient maintenance. Remote control devices and power transformers are installed in the low-voltage compartment to achieve remote control and self-power supply of the box-type substation, meeting the needs of photovoltaic and wind power generation systems.
