[0007] As a preferred solution of the utility model, the front cover plate is provided with an inlet and outlet wire bushing, and the side plate is provided with a side expansion bushing.

[0008] As a preferred solution of the utility model, an isolation mechanism and a circuit breaker mechanism are sequentially installed on the outer side of the front cover plate from top to bottom.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model adopts D-shaped round steel as reinforcement ribs, which have no sharp points compared to the square steel reinforcement ribs in the prior art, and the discharge inside the gas box will be smaller, thus avoiding damage to equipment such as disconnectors and extending the service life of the gas box. In addition, the D-shaped round steel is made by cold drawing process, which has a simple process, while the process of square steel is more complicated. Usually, the price of square steel will be higher than that of D-shaped round steel of the same grade, so the production cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figures 1 to 4 The utility model provides a technical solution: an environmental protection cabinet gas box, comprising a front cover plate 1, a rear sealing plate 2 connected to the front cover plate 1, and side plates 3 arranged on both sides of the front cover plate 1 and the rear sealing plate 2. A plurality of reinforcing ribs 9 are arranged between the front cover plate 1 and the rear sealing plate 2. The cross section of the reinforcing rib 9 is D-shaped. Compared with the square steel reinforcing ribs in the prior art, there is no sharp tip, and the discharge inside the gas box will be smaller, thereby avoiding damage to equipment such as an isolating switch 8 and extending the service life of the gas box. An isolating switch 8 is installed between the front cover plate 1 and the rear sealing plate 2. A cam equalizing cover 11 is provided at the bottom of the isolating switch 8. The cam equalizing cover 11 is used to make the electric field uniform, thereby preventing breakdown caused by excessive electric field density. Screw covers 10 and soft connection covers 12 are provided on both sides of the isolating switch 8. The screw covers 10 are used to shield the screws, and the soft connection covers 12 are used to shield the soft connectors, thereby avoiding tip discharge.

[0017] Among them, the reinforcing rib 9 is a D-shaped round steel, which is made by cold drawing process, and the process is simple, while the process of square steel is more complicated. Usually, the price of square steel is higher than that of D-shaped round steel of the same grade, so the production cost can be reduced.

[0018] Among them, the front cover plate 1 is provided with an inlet and outlet bushing 4, and the side plate 3 is provided with a side expansion bushing 7. The inlet and outlet bushing 4 and the side expansion bushing 7 are used to provide electrical insulation, isolate the cable from the external environment, prevent current leakage into the surrounding environment, ensure the safety of electrical equipment and operators, and can also provide support and fixation for the cable to prevent the cable from moving or swinging, reducing the risk of electrical connection failure due to mechanical stress.

[0019] Among them, the outer side of the front cover plate 1 is installed with an isolation mechanism 6 and a circuit breaker mechanism 5 in sequence from top to bottom. The circuit breaker mechanism 5 and the isolation mechanism 6 are used to rotate the transmission shaft of the disconnector 8 to operate the disconnector 8. The isolation mechanism 6 and the circuit breaker mechanism 5 are both existing technologies and are not described in detail.
