The invention discloses an intelligent testing device of a built-in load switch of an electric energy meter. The intelligent testing device of the built-in load switch of the electric energy meter aims to overcome the defects of existing technical equipment for detecting the electric energy meter. The intelligent testing device of the built-in load switch of the electric energy meter is composed of a computer, a control unit, a meter position display unit, a measurement channel switching unit, a load gear switching unit, a relay parameter measuring unit, a waveform monitoring unit, a withstanding voltage testing unit, a load unit and a load parameter measuring unit. The intelligent testing device of the built-in load switch of the electric energy meter has the advantages that testing of the load switch of the electric energy meter can be achieved, the service life of the built-in load switch of the electric energy meter can be predicted accurately and reasonably due to the fact that testing is carried out under the actual load condition, the testing efficiency is improved by 40% compared with that achieved manually, requirements of the State Grid Corporation of China are met, and potential safety hazards are reduced.
