The invention provides a turntable device with a heavy-current output used for an anechoic chamber. The turntable device comprises an upper-layer turntable and a lower-layer turntable which are fixedly connected with each other, wherein a heavy-current generating device is arranged on the lower-layer turntable; the heavy-current generating device comprises three transformers with multiple magnetic circuits, three voltage regulators and a control cabinet; the control cabinet is connected to the three voltage regulators; and the three voltage regulators are connected to the corresponding transformers with multiple magnetic circuits. Compared with the prior art, the turntable device provided by the invention has the advantages that: 1) since a double-layer turntable structure with heavy-current output is adopted, electromagnetic compatible emission measurement can be performed on a high-voltage electric device and the problems which cannot be solved by an ordinary turntable can be solved; 2) a power feeding line is connected to the heavy-current generating device through a filter, thereby ensuring an electromagnetic shielding property of a measured device, promoting the measuring accuracy and preventing a power grid from being interfered by a harmonic wave generated by the voltage regulators; and 3) the measured device and the heavy-current generating device are connected through three lifting copper bars, so that the connection in a test process is convenient.
