The invention discloses an anti-electric shock switch cabinet with an automatic pressure relief function. The anti-electric shock switch cabinet comprises a cabinet box, a power supply main body, an air guide unit, a refrigeration unit and a pressure relief unit. The power supply main body is mounted on the left side in the cabinet box, and the air guide unit and the refrigeration unit are mounted in the cabinet box. The pressure relief unit comprises a pressure relief channel, a check block, a spring and a supporting block, notches are formed in the upper side of the cabinet box at equal intervals, the check block is rotatably connected with the two sides of the interior of each notch through a fixing shaft, the check block is attached to the notches in a matched mode, and the pressure relief channel is installed in the position, corresponding to the notches, of the upper side of the interior of the cabinet box; and the supporting block is installed on the right side of the interior of the pressure relief channel, the bottom end of the spring is connected with the upper side of the supporting block, the upper end of the spring is connected with the right end of the bottom side of the check block, if the pressure in the cabinet box is too large, the pressure relief channel can guide the pressure to punch up the check block, the spring stretches, the pressure relief efficiency is high, the cooling effect is good, and cooling is uniform.
Description
technical field [0001] The invention relates to the technical field of automatic pressure relief, in particular to an electric shock-proof switchgear with automatic pressure relief function. Background technique [0002] Switchgear is an electrical device that performs switching, control and protection during the process of power generation, transmission, distribution and power conversion in the power system. [0003] In the prior art, the application number is 202020252997.0, which proposes an automatic pressure relief device for the functional room of the switchgear, including the switchgear, the pressure relief unit and the pressure relief plate limit unit. The upper surface of the switchgear body is provided with a pressure relief groove. A support plate is welded inside the switchgear body, and the pressure relief unit includes a hollow column. [0004] The pressure relief efficiency is low, the cooling effect is poor, and the cooling is uneven. Contents of the inven...
