Electric shock protection test system capable of simulating human body impedance

An electric shock protection test system capable of simulating human body impedance comprises a switch assembly, an adjustable electric shock impedance, an impedance controller and an impedance display module, and the switch assembly comprises a change-over switch and an air switch; the upper circuit of the adjustable electric shock impedor is connected to the air switch, and the air switch is selectively connected to the change-over switch; the lower circuit of the adjustable electric shock impedance is grounded; the adjustable electric shock impedance middle circuit is connected to the impedance controller, and the impedance controller is connected to the impedance display module. The electric shock impedance is based on a human body impedance model, can accurately simulate the electric shock condition of a human body compared with existing equipment, and can be used for testing the effectiveness and reliability of an electric shock protection method and device; the system has a fault phase selection functi
