Zusammenfassung:	The utility model provides a trans-regional integrated relay protection acquisition end power supply system comprising an AC power supply unit, a DC power supply unit and a switching control unit, theinput end of the AC power supply unit is connected with a power transmission line, the output end of the AC power supply unit is connected with the input end of the switching control unit, and the switching control unit is connected with the switching control unit. The direct-current power supply unit is powered by a storage battery, the output end of the direct-current power supply unit is connected with the input end of the switching control unit, and the output end of the switching control unit is the output end of the power supply system. By adopting a mode of supplying power to the acquisition unit by double currents, uninterrupted continuous power supply of the acquisition unit is ensured, power data can be normally acquired even during power-off maintenance, and the reliability ofcross-regional integrated
