Centralized remote electric power system

The invention relates to a centralization remote power feeding system including a primary device machine room arranged with wireless primary devices and power supply primary devices, which include an inverter and a transmission primary device for converting the external electricity 380 V industrial electricity into the -48 to 24 V DC to access to the wireless primary devices to cause the wireless primary devices operate normally; the -48 to 24 V DC is converted to the 220-380V AC through the inverter of the power supply primary devices, then the power is transmitted to the farend unit of the farend covering system of the base station part newly built through the common rod transmission mode of the power transmission line and the optical fiber transmission line, providing the stable power to the farend unit, thereby completing the construction of the whole base station. The invention reduces the building size of the base station, saves the project invest and advances the net operation safety reliability, which
