[0002] Indoor AC high-voltage gas-insulated metal-enclosed switchgear, referred to as "inflatable cabinet", has the characteristics of high technical level, maintenance-free equipment, small footprint, safe and reliable performance, and no environmental impact (condensation, air humidity, dirt, etc.); it is widely used in important areas of the national economy such as the State Grid, Southern Grid, rail transit, large industrial and mining enterprises, petrochemicals, metallurgy, and new energy industries. With the increase in the use of inflatable equipment, under the dual-carbon strategy, the technical demand for environmentally friendly inflatable equipment is increasing day by day.

[0003] At present, modular inflatable switchgear mainly utilizes modular partitions to divide the cabinet body, thereby obtaining an installation room for installing various types of instrumentation and equipment. Although the use of partitions can modularize the cabinet body, various instruments and equipment are often fixed on the side walls or partitions of the installation room, which is extremely inconvenient in replacement and maintenance. At the same time, the operating space of the installation room is limited, which will seriously affect the maintenance of the inflatable switchgear and affect the normal use of the inflatable switchgear. Utility Model Content

[0004] In order to overcome the above technical defects, the utility model provides an environmentally friendly gas-filled switch device, which is based on modular design and assembly gradient. Each functional module can be quickly installed and replaced, which is conducive to ensuring the application and use of the gas-filled switch device.

[0007] The mechanism chamber and the pressure relief chamber are respectively arranged on opposite sides of the air box, the lower ends of the mechanism chamber and the pressure relief chamber are fixedly connected to the bottom cabinet, and the air outlet end of the air box is communicated with the pressure relief chamber;

[0008] The instrument box chamber is arranged on the upper side of the mechanism chamber, the lower end of the instrument box chamber is fixedly connected to the mechanism chamber, and the instrument box chamber is electrically connected to the gas box;

[0009] The overhead incoming line chamber is arranged between the upper end of the pressure relief chamber and the air box, the side of the overhead incoming line chamber is fixedly connected to the pressure relief chamber, and the lower end of the overhead incoming line chamber is electrically connected to the air box.

[0010] Furthermore, a radiator is provided at the bottom of the air box.

[0011] Furthermore, a partition is provided in the base cabinet, and the partition divides the interior of the base cabinet into a heat dissipation chamber and a pressure relief buffer chamber. The top wall of the heat dissipation chamber is provided with heat dissipation holes, and the radiator passes through the heat dissipation holes and extends into the heat dissipation chamber.
