Switch cabinet and pressure relief structure thereof

Abstract

The invention relates to the field of switchgear, in particular to a switch cabinet and a pressure relief structure thereof. The switch cabinet comprises a cabinet body, wherein the cabinet body is provided with a pressure relief port, the pressure relief port is provided with pressure relief plates, each pressure relief plate comprises a pressure relief connection part and a maintaining connection part which is used for enabling the corresponding pressure relief plate to be connected on the cabinet body always, and the pressure relief port is provided with a foldable sheltering plate which is positioned on one side, facing the pressure relief port, of the pressure relief plate and used for sheltering one side, close to the maintaining connection part, of the pressure relief port; or the pressure relief port is provided with a guide plate positioned on one side, facing the pressure relief port, of the pressure relief plate, and the guide plate is provided with a guide surface which is used for guiding arcing energy inside the cabinet body to a region, far away from the maintaining connection part, on each pressure relief plate; or, a distance between the pressure relief connection part and the pressure relief port is less than a distance between the maintaining connection part and the pressure relief port, so that the pressure relief port is arranged eccentrically relative to the pressure relief plates, thereby solving the problem that potential safety hazards exist in the existing pressure relief structure.

Description

technical field [0001] The invention relates to the field of switch equipment, in particular to a switch cabinet and a pressure relief structure thereof. Background technique [0002] The arc effects generated during the burning of the arc fault inside the switchgear include pressure effects, thermal effects, radiation and acoustic effects. These arcing effects are powerful and will damage switchgear and cause injury to nearby workers. Various switchgear manufacturers have adopted various measures to strengthen the switchgear to protect the switchgear from arcing faults. In addition to strictly ensuring the manufacturing quality of the switchgear, performing correct maintenance and operating accidents in accordance with relevant regulations, it is also necessary to design and configure fast-acting pressure relief structure, once an internal arcing fault occurs. In addition to strictly ensuring the manufacturing quality of the switchgear and performing correct maintenance a...
