The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
As described in the background art, for protecting the high-voltage accelerating tube, the safety of the accelerating tube in the actual operation process is improved, and the equalizing ring and the accelerating tube voltage divider can be installed for the accelerating tube in the actual use process of the high-voltage accelerating tube, so that the high voltage before and after the accelerating tube can be uniformly distributed on the accelerating tube in a high-voltage environment through the accelerating tube voltage divider, the electric field can be uniformly distributed, and the electrode slice tip can be prevented from generating corona ignition and tip discharge phenomena through the equalizing ring. Therefore, the embodiment provides the high-pressure accelerating tube protection device which has the advantages of simple structure, available materials, low manufacturing cost, simple operation and good protection effect.
A high-pressure accelerating tube protecting device of the present embodiment is described below with reference to the drawings.
Fig. 1 is a schematic diagram illustrating an installation of a high-pressure accelerating tube protection device on a high-pressure accelerating tube according to an embodiment of the present utility model. As shown in fig. 1, the high-voltage accelerating tube protection device comprises a plurality of accelerating tube voltage dividers 1 and a plurality of equalizing rings 2, wherein a plurality of electrode plates 4 are arranged on the high-voltage accelerating tube 3, the accelerating tube voltage dividers 1 are connected between two adjacent electrode plates 4 so as to realize uniform voltage distribution on the high-voltage accelerating tube 3, and each electrode plate 4 is sleeved with the equalizing ring 2 so as to prevent the tip discharge of the electrode plate 4.
Specifically, the high-voltage accelerating tube 3 in the embodiment has 17 electrode plates 4, and adopts a multi-stage high-voltage accelerating ring-changing structure, so that the voltage difference between the electrode plates 4 can be almost the same. In the actual operation process, the high voltage between the head and the tail of the high-voltage accelerating tube 3 rises from zero to about 216KV, so that 12KV high voltage can be added between every two electrode plates 4. When the current is the same, a resistor with a resistance value of 100 megaohms, namely a preset resistance value, namely the accelerating tube voltage divider 1 can be additionally arranged between every two electrode plates 4, so that the voltage between every two electrode plates 4 can be ensured to be basically the same.
In this embodiment, the inside of the high-voltage accelerating tube 3 is a vacuum structure, and the outside of the accelerating tube is formed by sequentially connecting an electrode plate 4 and glass 5, wherein the glass 5 is arranged between adjacent equalizing rings 2 and is close to the tip end position of the electrode plate 4, and the conductivity of the glass 5 is poor. The part, close to the glass 5, inside the electrode plate 4 is provided with a plurality of round holes, and the accelerating tube voltage divider 1 can be fixed on the round holes in a head-tail mode. In this example, the radius of the glass 5 is 12.516cm, the thickness is about 2.6cm, the radius of the electrode sheet 4 is 14.516cm, the distance between 17 electrode sheets 4 is 40cm, and the total length of the high-pressure accelerating tube 3 is 53cm.
In this embodiment, the accelerating tube voltage divider 1 is connected by welding 20 resistors of 5 megaohms in series, so that the resistor string, i.e., the resistor of the accelerating tube voltage divider 1 is about 100 megaohms. The outer part of the accelerating tube voltage divider 1 is sleeved with polytetrafluoroethylene tubes with the outer diameter of 10mm and the inner diameter of 8mm so as to prevent wires at the connecting part of the resistor from contacting other parts of the equipment.
The accelerating tube voltage divider 1 is sleeved with polytetrafluoroethylene tubes with the outer diameter of 10mm and the inner diameter of 8mm, current passes through the resistor string, and the polytetrafluoroethylene tubes ensure the insulation of the resistor string. When current flows through the electrode sheet 4, the thickness of the outermost layer is only 1mm as the electrode sheet 4 is of a disk structure and is thinner as it approaches the edge. According to the principle of tip discharge, the degree of charge accumulation varies with the degree of surface density of the conductor. The tip portion with larger curvature on the metal electrode is easier to collect charges, so that the tip position of the electrode sheet 4 is easier to generate discharge to generate arc, that is, the tip of the electrode sheet 4 is extremely easy to generate a tip discharge phenomenon. Therefore, in this example, the outer diameter of the electrode sheet 4 was bent by using a equalizing ring 2, which is a red copper hose having an outer diameter of 5mm and a thickness of 0.5mm, and a slit having a slit width of 2mm was cut out, and then the slit was fitted over each electrode sheet 4. Therefore, the tip thickness of the electrode plate 4 is changed from 1mm to 2.5mm, so that the probability of the tip discharge of the electrode plate 4 can be greatly reduced, the electric field of the high-voltage accelerating tube 3 is ensured to be uniform and safe to run, the safety of equipment is ensured, and the service life of the equipment is prolonged.
The perspective schematic diagrams of the high-pressure accelerating tube 3 before and after the sleeve equalizing ring 2 are shown in fig. 2 (a) and 2 (b) below.
Before the grading ring 2 is sleeved, the thickness of the edge of the electrode plate 4 is 1mm, namely as shown in fig. 2 (a). After the grading ring 2 is sleeved, the thickness of the edge of the electrode plate 4 is 2.5mm, namely as shown in fig. 2 (b).
In the embodiment, the grading ring 2 is sleeved to increase the tip thickness of the electrode plate 4, so that the probability of tip discharge can be reduced.
In summary, the accelerating tube voltage divider is connected between all the two adjacent electrode plates on the high-voltage accelerating tube, so that the voltage on the high-voltage accelerating tube can be uniformly distributed, and the equalizing rings with preset slit widths and preset thickness are sleeved on each electrode plate, so that corona ignition and discharge phenomena at the tips of the electrode plates can be prevented, and the safety of the high-voltage accelerating tube in the operation process can be improved.
