Insulated gas moisture monitoring system and method used for accelerator

Abstract

The invention discloses an insulated gas moisture monitoring system for an accelerator. The system is combined with a main steel cylinder of the accelerator. The insulated gas moisture monitoring system for the accelerator includes a gas treatment component, a moisture monitoring device and a controller. The gas treatment component and the moisture monitoring device are electrically connected withthe controller, the moisture monitoring device is combined with the main steel cylinder of the accelerator to monitor the moisture content, the gas treatment component is connected with the main steel cylinder of the accelerator through a pipeline, and the gas treatment component is controlled by the controller to drying the gas in the main steel cylinder of the accelerator in cycle. The invention further discloses an insulating gas moisture monitoring method for the accelerator, and the control device centrally monitors the moisture content in gas and controls the gas treatment component forcyclic drying.

Description

technical field [0001] The invention relates to the technical field of electron accelerators, and more precisely relates to a monitoring system and method for insulating gas moisture used in accelerators. Background technique [0002] When the electron accelerator is working, the main steel cylinder of the accelerator has a relatively high voltage. In the prior art, a certain pressure of SF is usually filled in the main steel cylinder. 6 (sulfur hexafluoride) insulating gas to improve the insulation performance between devices. Sulfur hexafluoride is a colorless, odorless, non-toxic, non-flammable, non-corrosive inert gas under normal conditions. It has strong chemical stability, good insulation performance and arc extinguishing performance. At the same time, it can be miniaturized as much as possible to reduce equipment cost. SF6 gas is insoluble in water and transformer oil, and it does not interact with oxygen, argon, aluminum and many other substances at hot temperatur...

AI Technical Summary

Problems solved by technology

In order to prevent the sulfur hexafluoride gas inside the main steel cylinder of the accelerator from increasing the moisture content with the increase of the use time, resulting in a drop in pressure resistance and even damage to the equipment

The existing solution is only to periodically dry the SF6 gas in the tank through back and forth gas conduction and gas storage. With this solution, it is impossible to monitor the moisture content of the gas inside the main steel cylinder of the accelerator during the working process of the electron accelerator, and this solution The drying effect is poor, the drying takes a long time, and the accelerator needs to be completely shut down, which affects the production efficiency
