The invention relates to a 1600kV / 50mA outdoor mobile
direct current voltage generator which comprises a
direct current voltage generator body, a charging
voltage regulation device and a computer measuring and controlling
system; the
direct current voltage generator body adopts a five-stage voltage doubling rectifying circuit with symmetrical single sides, the complete set of the test units adopts a
tower type combined structure and a container transportation method as well as the
modular design. A direct-
current voltage generator body module, the charging
voltage regulation device, a computer measuring and controlling
system operating platform are respectively provided with hoisting devices, and the hoisting devices can be moved on a transport vehicle; the invention utilizes the 50Hz
power frequency power supply as the
rectifier source to obtain the direct-
current voltage, the quality of the direct-current power supply is good, the capacity is large, and the demands of experimental investigation of the extra-
high voltage direct current transmission project can be met; and due to the adoption of the
modular design, the rapid
assembly and disassembly can be realized on site, and the polarity can be changed according to the complete set of the test units with required testing voltage.
