The invention belongs to the
power transmission and transformation equipment field and relates to an energy-saving box type outdoor substation. The substation comprises a top cover and a box body; the box body is divided into a high-
voltage chamber, a
transformer chamber and a low-
voltage chamber. The energy-saving box type outdoor substation further comprise an intelligent controller; the intelligent controller is connected with a low-
voltage chamber
power transmission line through a power source input cable; the high-voltage chamber is provided with a high-voltage entering cabinet, a high-voltage metering cabinet, a high-voltage ring main unit and a high-voltage outgoing cabinet; the low-voltage chamber is provided with a low-voltage entering cabinet, a high-voltage reactive power automatic compensation
capacitor cabinet and a low-voltage outgoing cabinet; and a
transformer arranged in the
transformer chamber is an on-load automatic
capacitance adjustment power
distribution transformer. The energy-saving box type outdoor substation is safe, reliable, energy-saving and efficient. With the energy-saving box type outdoor substation adopted, a
power factor as well as the power supply efficiency and voltage quality of a
system can be improved, and
line loss can be decreased, and distribution line cost can be decreased, and
electric energy can be saved, and the occupancy of a
power grid and the no-load reactive loss and active loss of the transformer can be decreased, and capacity increasing cost and operation cost can be saved, and saving energy and consumption reduction can be realized, and great
economic benefits and
social benefits can be brought about.
