Embodiment Construction

[0033] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, the high-power microwave vacuum tube cathode and filament connector includes a base support structure 5 at the bottom, a wire cover 4 installed on the upper end of the base support structure 5, a cathode connector 2 installed on the upper end of the wire cover 4, and a cathode connector 2 installed on the upper end of the base support structure 5. The inner filament connector 1 and the support spring 3 are installed between the bottom of the cathode connector 2 and the base support structure 5 .

[0035] Such as Figure 2a and Figure 2b As shown, the cathode connector 2 is a cylindrical structure with a certain wall thickness, the inner bottom is processed into a stepped structure with a gradually decreasing inner diameter, and the lower end of the outer wall of the cylinder is processed with a boss. A terminal 7 i...

Abstract

The invention belongs to the field of plasma heating, and particularly relates to a high-power microwave vacuum tube cathode and lamp filament connector which comprises a base supporting structure atthe bottom, an electric wire cover arranged at the upper end of the base supporting structure, a cathode connector arranged at the upper end of the electric wire cover and a lamp filament connector arranged in the cathode connector. A supporting spring is arranged between the bottom of the cathode connector and the base supporting structure; and an insulating sleeve is arranged at the bottom outside the filament connector. The device can ensure the connection between the high-power microwave vacuum tube and the high-voltage line, ensures good high-voltage electric contact, is easy to disassemble and assemble, eliminates the influence of the error through the structural design of the cathode and the filament connector, and ensures that the cathode and the filament interface of the high-power microwave vacuum tube are accurately butted with the connector, and the electric contact is good.

Description

technical field [0001] The invention belongs to the field of plasma heating, and in particular relates to a cathode and a filament connector of a high-power microwave vacuum tube of a low-clutter heating device. Background technique [0002] The high-power microwave vacuum tube is a high-power microwave source with an output power of the order of megawatts, a cathode high voltage of tens of kilovolts, a filament power of hundreds of kilowatts, and a tube weight of the order of tons. In the low-clutter heating system of a fusion device, a foreign 500kW high-power microwave vacuum tube is used. The installation and commissioning of the vacuum tube are carried out in China. In order to facilitate the installation and debugging of high-power microwave tubes, high-voltage wires cannot be directly welded to the cathode and filament interfaces of vacuum tubes, so a connector needs to be designed to complete the connection between high-power microwave vacuum tubes and high-voltage ...
