Abstract
The invention discloses a high-pressure type accelerator which comprises an accelerator body. An air inlet and an air outlet are formed in the two sides of the lower end of the accelerator body. Insulating gas which is sulfur hexafluoride is filled in the interior of the accelerator body. The high-pressure type accelerator solves the problem that in the prior art, the accelerator fails to obtain higher energy due to the fact that the insulating gas in the accelerator is not good in the insulating property. Due to the fact that the sulfur hexafluoride is filled in the accelerator, the good electronegativity of the sulfur hexafluoride is utilized to have the functions of absorbing electron energy and causing electron attachment to extinguish electrons, the accelerator is enabled to have higher insulating capability and excellent arc extinguishing performance, the whole performance of the accelerator is improved, the accelerator is enabled to be capable of obtaining the higher energy, and therefore a design objective is achieved, the cost is low, and the sulfur hexafluoride can be reused.
Description
Technical field
The present invention relates to a kind of high-pressure type accelerator, belonged 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 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 the higher accelerator of energy accelerator as above in 3MV, the energy exercise time is long, and the more difficult rated energy index that reaches need be filled with 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.
Summary of the invention
Technical problem to be solved by this invention is to provide 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 technology used in the present invention problem 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 invention has the beneficial effects as follows: 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 betatopic effect that disappears, 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 present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
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 at the insulating gas of the interior filling sulphur hexafluoride of accelerator body 1 as accelerator, this kind gas and nitrogen, carbon dioxide gas mixture is compared, sulphur hexafluoride is good electronegative gas, there is the absorption electron energy to eliminate the effect of electronics with making electron attachment, thereby have high insulating capacity and a superior arc extinction performance, insulating capacity under 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 it is high to have breakdown strength, nontoxic, do not burn and good thermal stability and chemical stability, the blowing pressure low (only needing 6.5 kilograms) has reduced main copper cylinder cost of manufacture.High pressure is taken exercise easily, thereby improved the accelerator overall performance, this kind insulating gas can be reused by certain equipment, 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 damaging accelerator because of the insulating gas excess Temperature.
In sum, a kind of high-pressure type accelerator provided by the invention 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.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
