[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, an electrical cabinet with a fully open top includes a cabinet body 1 and two top panels 2.

[0031] like Figure 2 As shown, there is a crossbeam 3 in the middle position of the top of the cabinet 1, and the crossbeam 3 is arranged along the left and right directions of the cabinet 1; a plurality of hinges 4 are provided on the crossbeam 3 along its length direction; the two top panels 2 are hinged to the crossbeam 3 through the hinges 4 respectively, so as to close the top of the cabinet 1; bolts are provided at the corner positions of the top panel 2 away from the hinge 4, and the bolts detachably fix the side of the top panel 2 away from the hinge 4 to the top of the cabinet 1.

[0032] In this embodiment, a plurality of heat dissipation holes 5 are evenly arranged on the top plate 2 to facilitate heat dissipation.

[0033] In this embodiment, the top corners of the cabinet 1 are vertically fixed with hanging ears 6. Figure 4 As shown, a avoidance area 7 is provided at the position of the top plate 2 facing the lifting ear, so as to avoid interference with the lifting ear 6 when the top plate 2 closes the top of the cabinet 1 .

[0034] like Figure 3 As shown, the bottom of the cabinet 1 is evenly provided with a plurality of circular holes 8, and a cover plate 9 is provided on each of the circular holes 8.
