Technical Field

[0001] The invention belongs to the technical field of power transmission and distribution equipment of a power system, and in particular relates to a universal gas box reinforcement device for a gas insulated switchgear and a use method thereof. Background Art

[0002] With the popularization of power systems, electric energy has become an indispensable part of people's daily life. C-GIS equipment (Cubicle type Gas Insulated Switchgear) is a distribution equipment specially used in medium voltage systems developed at the end of the last century. Its outstanding safety and reliability have enabled it to develop rapidly at the beginning of this century and has been rapidly developed and applied in my country's current transmission and distribution network system.

[0003] However, when C-GIS equipment is deployed in high-altitude areas, the air pressure of their air boxes will be significantly affected. The increase in altitude will cause the atmospheric pressure to gradually decrease, resulting in a more obvious pressure difference between the inside and outside of the C-GIS equipment air box. Because the main components of C-GIS are installed in a sealed inflatable air box, when the pressure difference between the inside and outside is too large, it is easy to cause damage to the air box. Therefore, it is urgent to design different air box designs for C-GIS equipment required in different altitudes. Summary of the invention
