Problems solved by technology
[0003] Since each traveling wave tube is a vacuum electronic device made by hand, its working parameters cannot be consistent. In the past transmitters, the voltage of each pole of the transmitter power supply was artificially adjusted to meet the needs of the traveling wave tube.
This increases a lot of procedures to a certain extent, wastes a lot of time, increases the difficulty of replacing the traveling wave tube, and the adjustment of the electrode voltage needs professionals to operate, which brings great inconvenience to the military; would result in fatal loss

Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] see Figure 1-Figure 5 , this embodiment takes a high-power pulse traveling wave tube used in a certain transmitter as an example. When the transmitter is not installed with a traveling wave tube, the output voltage parameters are: the heating wire voltage is 11V, the cathode voltage is -35kV, the grid The pole pulse voltage is 510V; and the parameters of a TWT after the state is adjusted are: hot wire voltage 10V, cathode voltage -34.5kV, grid pulse voltage 410V.
[0026] In order to be able to install the traveling wave tube on the transmitter and make it work under the state of adjusted electrical parameters.
[0027] In the present invention, the voltage of the traveling wave tube is adjusted to be consistent with the power supply of t...

The invention belongs to the field of vacuum electronic devices and the matching field of high-voltage power supply, and particularly relates to a voltage regulating method of a traveling wave tube in consistence with a transmitter power supply. The regulating method includes regulating methods of a grid impulse voltage of the traveling wave tube, a heater voltage, and a slow-wave voltage of the traveling wave tube. By regulating the grid impulse through a circuit packaged in a traveling wave tube electron gun, a normal working voltage needed by the traveling wave tube is achieved, and by regulating the slow-wave voltage of the traveling wave tube through an electric resistance installed on the traveling wave tube, a slow-wave voltage needed by the traveling wave tube is achieved accurately. The regulating method of the invention can guarantee high consistency of the production of traveling wave tube power supplies, avoid man-made regulation of a power supply voltage in ordinary transmitter power supplies, and achieve the working voltage needed by the traveling wave tube.
Description
technical field [0001] The invention belongs to the field of vacuum electronic devices and the matching high-voltage power supply, and in particular relates to a traveling wave tube adjustment method for improving the production consistency of transmitter power supplies. Background technique [0002] As a vacuum microwave power amplifier, traveling wave tubes have the advantages of wide frequency band, large gain, high efficiency, and large output power. They are widely used in various military microwave transmitters and are known as the "heart" of weapons and equipment. [0003] Since each traveling wave tube is a vacuum electronic device made by hand, its working parameters cannot be consistent. In the past transmitters, the voltage of each pole of the transmitter power supply was artificially adjusted to meet the needs of the traveling wave tube. . This increases a lot of procedures to a certain extent, wastes a lot of time, increases the difficulty of replacing the trav...
