Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, a high-voltage accelerator includes an accelerator main body 1, an air inlet 2 and an air outlet 3 are arranged on both sides of the lower end of the accelerator main body 1, and the inside of the accelerator main body 1 is filled with an insulating gas 4. Gas 4 is sulfur hexafluoride.

[0012] The accelerator body 1 is filled with sulfur hexafluoride as the insulating gas of the accelerator. Compared with the mixed gas of nitrogen and carbon dioxide, sulfur hexafluoride is an excellent electronegative gas, which can absorb electron energy and make electrons attach and eliminate The function of electrons, so it has high insulation ability and superior arc extinguishing performance. The insulation ability under the same pressure is 2.5 times that of air or nitrogen, and the arc extinguishing ability under one atmospheric pressure is eq...

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 [0001] The invention relates to a high-pressure accelerator, which belongs to the technical field of accelerator manufacturing. Background technique [0002] In order to make the accelerator obtain higher energy, so as to reach the design index. Effectively inhibit the phenomenon of high-voltage ignition breakdown of the accelerator, avoid damage to accelerator components due to ignition, and use insulating gas with high insulation capacity and superior arc-extinguishing performance, which is a very important problem to solve for high-voltage accelerators . [0003] Early accelerators used 75% nitrogen and 25% carbon dioxide, which were mixed as the insulating gas of the accelerator. Due to the low withstand voltage of nitrogen and carbon dioxide mixed gas, for accelerators with higher energy such as accelerators above 3MV, the energy training time is long, and it is difficult to reach the rated energy index. It is necessary to fill in a higher pressure ins...
