Substation classification

1. According to the voltage level can be divided into ultra-high voltage, high voltage, medium voltage substation and low voltage substation. The voltage below 1kV is called low voltage; the voltage of 1 ~ 10kV is called medium voltage; the voltage higher than 10kV and lower than 330kV is called high voltage; the voltage above 330kV is called ultra high voltage. 2. According to the difference of power supply object, it can be divided into urban substation, industrial substation and agricultural substation. 3. According to its low position and function in the power system, it can be divided into hub substation, intermediate substation, regional (local) substation, enterprise substation and end (user) substation.

From photovoltaic power generation to "lighthouse factory", the switchgear company will be "green low carbon" into the enterprise gene

"During the peak season of photovoltaic power generation, the photovoltaic power generation system generates up to 200000 kWh per month, and the renewable energy (electricity) generated can be immediately consumed by production, and the remaining power can be automatically fed back to the grid, enabling the remaining power to be connected to the grid. The project not only helped the plant save millions of electricity bills, but also provided the grid with millions of kWh of clean energy." This is the roof photovoltaic project of Shanghai Siemens Switch Co., Ltd., and it is also the roof photovoltaic project with the largest installed capacity of Siemens in China.
