Description
Technical Field
The invention particularly relates to a switch cabinet and a cabinet body thereof.
Background
When a fault occurs inside the switch cabinet, the arc effect (including pressure effect, heat effect, radiation effect and acoustic effect) can be generated by fault arc combustion. The large amount of arc effect energy can not only damage the switchgear, but also cause injury to nearby workers. Various measures for strengthening the switch cabinet are taken by each switch cabinet manufacturer to protect the arcing fault of the switch cabinet. However, most manufacturers often neglect the contradictory problems of the cable chamber lighting device and the internal arcing fault protection during design. When arcing faults occur in the switch cabinet, the thermal effect and the pressure effect are enough to melt and destroy the lighting device, so that arcing energy is released from the rear of the cabinet, and the requirements of IAC-level switch equipment and control equipment cannot be met.
To solve the above problem, chinese patent CN201475786U discloses a switch cabinet cable chamber lighting device, which comprises a fixing frame body, a transparent cover and a device panel, wherein one side surface of the fixing frame body is fastened on the cabinet body, the device panel is arranged at the front side concave part of the fixing frame, and the right side of the device panel is connected with the transparent cover to form a hollow inner cavity. This cubical switchboard lighting device can prevent to a certain extent that the arcing from rushing out outside the cabinet, but the switch is the plastics button, and when taking place the arcing in the cubical switchboard, the plastics switch is probably struck and is destroyed to lead to the cubical switchboard internal pressure to let out, lead to the threat to the safety of the personnel outside the cabinet.
