Background
At present, the domestic and foreign treatment method for high micro-water content of SF6 high-voltage electrical equipment is mainly characterized in that after power failure and vacuum pumping are carried out, nitrogen gas is flushed and qualified new gas is injected again. The method not only needs power cut for processing, but also needs power cut to reduce the pressure of the air chamber when an adjacent air chamber is met. The workload is large and cumbersome.
The existing method for treating the micro-water content of SF6 high-voltage electrical equipment requires power failure of power grid equipment and large-scale equipment and SF6 fresh gas; a large amount of manpower and material resources are consumed.

The invention aims to provide a brand-new treatment method for respiratory SF6 high-voltage electrical equipment with high micro-water content and no power failure. And on the basis that power failure of the power grid equipment is not needed, the defect processing work is carried out by using less manpower and material resources.
Based on the above, the invention designs a respiratory SF6 high-voltage electrical equipment charged micro-water treatment device and method to solve the above problems.
