Description
Technical field
The invention belongs to a kind of glow-discharge electrode, be specifically related to a kind of electrode of improved electric insulation, can be applicable to the Glow Discharge Cleaning in large, medium and small fusion facility.
Background technology
In fusion field, Glow Discharge Cleaning, because it is simple to operate, energy consumption is little, and can reduce hydrogen concentration and part carbon oxygen impurities effectively, and by each device extensive use.During glow discharge, electrode is as anode, and vacuum chamber is as negative electrode, utilize the positive ion bombardment vacuum chamber wall under the acceleration of cathode sheath layer, the foreign particle being adsorbed on wall is bombarded out, then by vacuum-pumping system withdrawing device, reach the object that wall cleans, takes exercise.But during aura, the foreign particle sputtering may be deposited on the each surface of electrode after out again, as accumulated, too much can affect the insulation property between electrode and vacuum chamber.The present invention is deposited on the each surface of electrode again for reducing foreign particle, proposes a kind of electrode of improved electric insulation.
Summary of the invention
The object of this invention is to provide a kind of electrode of electrically insulated structures, it can reduce foreign particle and be deposited on the each surface of electrode again, improves the insulation property between electrode and vacuum chamber.
The present invention realizes like this, a kind of electrode of electrically insulated structures, it comprises anti-deposit back-up block, electrode tip again, by bolts and nuts, will prevent depositing back-up block, electrode tip, the first insulating ceramics assembly and the 3rd insulating ceramics assembly links together again, butterfly gasket is placed on the first insulating ceramics assembly and the 3rd insulating ceramics assembly, the second insulating ceramics assembly is arranged on the first insulating ceramics assembly, electrode tip cover plate point is welded in electrode tip surface, vacuum chamber set bolt by electrode supporting in vacuum chamber.
Described deposit back-up block and electrode tip surrounding again and have the gap of 5mm, groove lower plane has certain inclined plane of radian continuously therein, forms greatest gradient 1.5mm gap with electrode tip bottom surface section contact-making surface.
The described whole anti-back-up block inner groovy surface that deposits again scribbles the second insulating ceramics coating and electrode tip surrounding and lower surface and is evenly sprayed with the first insulating ceramics coating.
Advantage of the present invention is, 1, reduce the foreign particle sputtering and be deposited on the each surface of electrode; 2, improve the insulation property between electrode and vacuum chamber; 3, simple, the installation of system configuration and convenient disassembly etc.
Accompanying drawing explanation
Fig. 1 is the electrode structure schematic diagram for a kind of electric insulation provided by the present invention.
Wherein: the 1 anti-back-up block that deposits again; 2 electrode tips, 3 first insulating ceramics assemblies, 4 second insulating ceramics assemblies, 5 bolts, 6 butterfly gaskets, 7 electrode tip cover plates, 8 first insulating ceramics coatings, 9 second insulating ceramics coatings, 10 the 3rd insulating ceramics assemblies, 11 nuts, 12 vacuum chamber set bolts.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, a kind of electrode of the electrically insulated structures for glow-discharge electrode comprises and anti-deposits back-up block 1, electrode tip 2, insulating ceramics assembly 3,4,10 again, butterfly gasket 6, bolt 5, electrode tip cover plate 7, insulating ceramics coating 8,9, nut 11, vacuum chamber set bolt 12.
By bolt 5 and nut 11, will prevent depositing back-up block 1, electrode tip 2, the first insulating ceramics assembly 3 and the 3rd insulating ceramics assembly 10 links together again, butterfly gasket 6 is placed on the first insulating ceramics assembly 3 and the 3rd insulating ceramics assembly 10, the second insulating ceramics assembly 4 is arranged on the first insulating ceramics assembly 3,7 of electrode tip cover plates are welded in electrode tip 2 surfaces, vacuum chamber set bolt 12 by electrode supporting in vacuum chamber.
Depositing back-up block 1 and electrode tip 2 surroundings has the gap of 5mm again, groove lower plane is made with certain inclined plane of radian continuously therein, form greatest gradient 1.5mm gap with electrode tip bottom surface section contact-making surface, the whole anti-back-up block 1 inner groovy surface that deposits again scribbles the second insulating ceramics coating 9 and electrode tip 2 surroundings and lower surface and is evenly sprayed with the first insulating ceramics coating 8.During glow discharge, bombardment a large amount of foreign particles out only have small part to enter anti-back-up block 1 and electrode tip 2 surroundings of depositing again by the gap of 5mm, and most of foreign particle is extracted vacuum chamber out by vacuum-pumping system.Due to anti-back-up block 1 groove upper surface and the electrode tip 2 lower surfaces formation greatest gradient 1.5mm gaps of depositing again, final major part can be deposited on the anti-plane on back-up block 1 groove that deposits again, can effectively reduce like this foreign particle sputtering and be deposited on the each surface of electrode tip 2, improve the insulation property between electrode and vacuum chamber.
