The utility model discloses a high-
voltage electric connector and a
radar traveling wave tube outer circulation testing device, and belongs to the technical field of
radar emission. The device comprises a
traveling wave tube, a
radio frequency test subsystem, a low-
voltage box, a high-
voltage oil tank and a cooling subsystem, the
radio frequency test subsystem outputs a
radio frequency signal to a
traveling wave tube, and the traveling
wave tube outputs a
signal to a load through a directional coupler; a pre-
amplifier, a control and protection circuit and a frequency converter are arranged in the low-voltage box; a high-voltage power supply, a filament and a modulation power supply are arranged in the high-voltage The high-voltage power supply supplies multiple paths of
high voltage to the
cathode of the traveling
wave tube, the collector, the filament and the modulation power supply respectively; the filament and modulation power supply floats on the
high voltage to generate a traveling
wave tube grid voltage and a filament voltage; the high-voltage box is a sealed case filled with
silicone oil and is connected with the traveling wave tube through a high-voltage electric connector. The device can be used for
independent function test, debugging and acceptance inspection of the traveling wave tube; and the method can also be used for debugging a high-voltage circuit, a filament and a modulation power supply which take the traveling wave tube as a load.
