Embodiment Construction

[0023] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the straight blocker includes two straight blocker corrugated waveguides (corrugated waveguide A1, corrugated waveguide B2), an insulating sleeve 3, a cooling water pipe 4, a cooling water inlet joint 5 and a cooling water outlet joint 6.

[0025] Such as Figure 2a As shown, the corrugated waveguide A1 or the corrugated waveguide B2 is processed with an insulating sleeve connecting flange 9, bounded by the insulating sleeve connecting flange 9, the inner end face of the corrugated waveguide A1 or the corrugated waveguide B2 is the waveguide docking end face 9, and the outer end face The end face is the waveguide sealing end face 7 .

[0026] The inner part of the corrugated waveguide A1 or the corrugated waveguide B2 is located inside the insulating sleeve 3, and the connecting flange 9 of the insulating sleeve is s...

Abstract

The invention belongs to the technical field of microwaves, and particularly relates to a water-cooled high-power electron cyclotron resonance heating system direct current blocking device which comprises a corrugated waveguide A, a corrugated waveguide B, an insulating sleeve and a cooling water pipe located outside the insulating sleeve, wherein the corrugated waveguide A and the corrugated waveguide B are relatively and coaxially placed, insulating sleeve connecting flanges are arranged on the corrugated waveguides, the inner side portions of the corrugated waveguides are located in the insulating sleeve, the insulating sleeve connecting flanges are clamped on the two sides of the insulating sleeve, and a certain gap is reserved between the waveguide butt joint end faces of the two corrugated waveguides. The insulating sleeve positions the metal waveguides on the two sides; a gap between waveguides is arranged, a transmission system and a microwave electron cyclotron pipe of an electron cyclotron transmission system connected separately with waveguides are isolated in an insulation mode. Different from common insulation isolation in the prior art, a cooling pipe structure is designed outside the insulation sleeve, and two effects are achieved, besides the cooling effect, microwaves leaked out of the gap between waveguides can be absorbed.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a water-cooled high-power electron cyclotron resonance heating system DC blocker. Background technique [0002] For electron cyclotron resonance heating systems, the wave source gyrotron usually requires an external high-voltage power supply to generate high-power microwaves. Generally speaking, the beam voltage of the gyrotron during normal operation is about 70kV. To ensure safety, the electron cyclotron resonance heating wave source system is usually The ground potential of the system is suspended to ensure the safety of the load under fault conditions. Since the microwave output port of the wave source is at ground potential and is connected to the transmission system, in order to isolate the electrical connection between the wave source and the load, a transmission component that can realize this electrical isolation—a DC blocker—is required in the transmissio...
