Abstract
The utility model discloses a high voltage type accelerator which comprises an accelerator body. Air inlet and air outlet are arranged on both sides of the lower end of the accelerator body. The inside of the accelerator body is filled with insulating gas, and the insulating gas is sulfur hexafluoride. According to the utility model, the problem that the accelerator cannot acquire higher energy, which is caused by that the insulating performance of the insulating gas in the accelerator is poor in the prior art, is solved; the inside of the accelerator body is filled with sulfur hexafluoride and excellent electronegativity of sulfur hexafluoride is used, thus the functions of electron energy absorbing, electron attaching and electron extinguishing are provided; the high voltage type accelerator has high ability of insulating and excellent performance of arc extinguishing; the overall performance of the accelerator is improved; the accelerator can acquire higher energy; a design index is met; the cost is low; and sulfur hexafluoride can be repeatedly used.
Description
Technical field
The utility model has related to a kind of high-pressure type accelerator, belongs to accelerator manufacturing technology field.
Background technology
In order to make accelerator obtain higher energy, thereby reach design objective.Effectively suppressing accelerator high voltage sparking punch-through, avoid accelerator components because of the damage due to the sparking, adopt to have high insulating capacity and the insulating gas of superior arc extinction performance, is the problem of a very important solution for the high-pressure type accelerator.
Early stage accelerator all adopts 75% nitrogen and 25% carbon dioxide, after mixing as the insulating gas of accelerator.Because nitrogen, titanium dioxide mist proof voltage are lower, for energy higher accelerator such as the above accelerator of 3MV, the energy exercise time is long, and difficulty reaches the rated energy index, need charge into the insulating gas of higher pressure, must reach 16 kilograms of atmospheric pressure.For safety, the accelerator body steel cylinder must be thickeied, thereby has increased manufacturing cost, and when steel cylinder is opened in the accelerator maintenance, gas all can only be bled off, and can't reuse.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-pressure type accelerator, by fill sulphur hexafluoride in accelerator body, utilizes its higher insulating capacity and superior arc extinction performance, makes accelerator can obtain higher energy, reaches design standard.
In order to solve the problems of the technologies described above, the technical problem that the utility model adopts is:
A kind of high-pressure type accelerator comprises accelerator body, and the both sides, lower end of described accelerator body are provided with air inlet and gas outlet, and the inside of described accelerator body is filled with insulating gas, and described insulating gas is sulphur hexafluoride.
Aforesaid high-pressure type accelerator is characterized in that: the upper end of described accelerator body is provided with gas cooler.
The beneficial effects of the utility model are: by fill sulphur hexafluoride in accelerator body, utilize the good elecrtonegativity of sulphur hexafluoride, the attract electrons energy is arranged and make electron attachment and the effect of disappearance electronics, make it have higher insulating capacity and superior arc extinction performance, improved the overall performance of accelerator, made accelerator can obtain higher energy, thereby reach design objective, and cost is lower, and sulphur hexafluoride can be reused.
Description of drawings
Fig. 1 is the structural representation of a kind of high-pressure type accelerator of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of high-pressure type accelerator comprises accelerator body 1, and the both sides, lower end of described accelerator body 1 are provided with air inlet 2 and gas outlet 3, and the inside of described accelerator body 1 is filled with insulating gas 4, and described insulating gas 4 is sulphur hexafluoride.
By filling sulphur hexafluoride in accelerator body 1 as the insulating gas of accelerator, this kind gas and nitrogen, carbon dioxide gas mixture is compared, sulphur hexafluoride is good electronegative gas, electron energy is eliminated electronics with making electron attachment the effect that absorbs is arranged, thereby have high insulating capacity and a superior arc extinction performance, insulating capacity under the same air pressure is air or nitrogen 2.5 times, the arc extinguishing ability is equivalent to 100 times of air under an atmospheric pressure, and has the breakdown strength height, nontoxic, do not burn and good thermal stability and chemical stability, the blowing pressure low (only needing 6.5 kilograms) has reduced main copper tube cost of manufacture.High pressure is taken exercise easily, thereby improved the accelerator overall performance, this kind insulating gas can be reused by certain device, through using proof, its insulation property are good, be a kind of for the optimal insulating gas of high-pressure type accelerator, make accelerator can obtain higher energy, thereby reach design standard.
The upper end of accelerator body 1 is provided with gas cooler 5, in the accelerator course of work, lowers the temperature by the gas in 5 pairs of accelerator body of gas cooler 1, avoids because of the too high accelerator that damages of insulating gas temperature.
In sum, a kind of high-pressure type accelerator that the utility model provides by fill sulphur hexafluoride in accelerator body, utilizes its higher insulating capacity and superior arc extinction performance, makes accelerator can obtain higher energy, reaches design standard.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
