Embodiment 2

[0042] Embodiment 2 of the switchgear of the present invention differs from Embodiment 1 in that: in Embodiment 1, the guide spoiler surface is inclined to the Y direction with the spoiler. In this embodiment, the spoiler can be arranged horizontally or tilt up.

Embodiment 3

[0043] Embodiment 3 of the switchgear of the present invention differs from Embodiment 1 in that: in Embodiment 1, the front side of the pressure relief cover is hinged to the cabinet body, and the spoiler is fixed on the front side wall of the pressure relief channel. In the embodiment, the front side of the pressure relief cover is hinged with the cabinet body, and the spoiler is fixed on the rear side wall of the pressure relief channel.

Embodiment 4

[0044] Embodiment 4 of the switchgear of the present invention differs from Embodiment 1 in that: in Embodiment 1, a flow hole is provided on the spoiler plate, and the wall surface of the flow guide vane at the flow hole, which is facing away from the Z direction, forms a guide spoiler. As for the flow surface, in this embodiment, the flow hole and the guide vane can also be omitted, and the wall surface of the spoiler facing away from the Z direction forms a guide spoiler surface.

Abstract

The invention relates to a switch cabinet and its cabinet body. The switch cabinet includes a cabinet body and switchgear. There is a pressure relief channel in the cabinet body. A pressure relief port connected with the pressure relief channel is provided on the cabinet body. A spoiler used to change the direction of the arcing airflow to consume the energy of the arcing airflow. The speed of the arcing airflow is slowed down during the process of reversing the arcing airflow, thereby reducing the impact of the arcing airflow on the pressure relief cover, and reducing the damage of the arcing airflow to equipment near the switch cabinet.

Description

technical field [0001] The invention relates to a switch cabinet and its cabinet body. Background technique [0002] The 35KV gas-insulated metal-enclosed switchgear is an indispensable special equipment in the power distribution system, and is widely used in power plants, petroleum, metallurgy and other industries for power transformation and distribution. When the traditional switchgear is short-circuited due to equipment failure, the impact of short-circuit arcing will cause an explosion in the switchgear, and the generated arcing airflow and debris will hurt the staff around the switchgear. [0003] The Chinese utility model patent with the authorized announcement number CN201927930U discloses a pressure relief device. The pressure relief device includes a top plate (that is, a pressure relief cover) and a limit device. , and the front edge of the top plate is fixed on the top front side of the cabinet body by several hinges, the rear edge of the top plate is fixed on t...
