Intelligent distribution network secondary system phase sequence automatic check apparatus

The invention discloses an intelligent distribution network secondary system phase sequence automatic check apparatus and relates to the technical field of power equipment. The intelligent distribution network secondary system phase sequence automatic check apparatus comprises a power supply apparatus, a voltage transformer, a current transformer, an acquisition apparatus, an A/D conversion apparatus, a processor and a display apparatus. After a distribution automation terminal is installed, when the phase sequence of phase wires is checked, phase wires to be detected of the voltage transformer, the current transformer and the automation terminal are connected, a lead-out wire of the acquisition apparatus is connected with the voltage transformer and the current transformer, after connection is completed, as long as the apparatus is started, three-phase current values, three-phase current phase values and voltage phase values of the phase wires to be detected of the automation terminal can be acquired, whethe
