Specific implementation mode
The embodiment 1 of the switchgear of the present invention is as shown in Figure 3 and Figure 4, including frame and the head cover in frame roof is arranged
3, frame includes the column 1 of hollow structure and the crossbeam 2 that is connect with the side of column 1, and column 1 and crossbeam 2 are C profile knot
The structural strength of structure, C profile is high, easy for installation, and the end face at the axial both ends of column 1 has opening, cross section and the cross of column 1
The side of beam 2 is concordant；In other embodiments, the steel construction of the hollow types such as column 1 or square steel.
Head cover 3 is fixedly connected by head cover connector 4 with column 1.Head cover connector 4 be L-type structure gusset, gusset by
Plank one bending is formed, and the structural strength of gusset is high, easy to make；In other embodiments, the gusset of L-type structure can also
It is welded and is formed by two plates；Head cover connector may be the bend pipe of L-type or the cylinder of L-type, bend pipe or cylinder and head cover and
Column is bolted.There is the gusset of L-type orthogonal two flangings, two flangings to be pasted respectively with column 1, head cover 3
It closes, two flangings are correspondingly formed the head cover interconnecting piece 41 for being connect with head cover 3 and the column interconnecting piece for being connect with column 1
42, head cover interconnecting piece 41 is located at the opening on the end face of column 1.It is additionally provided with and prolongs on the column interconnecting piece 42 of head cover connector 4
Direction escape groove 43 identical with the extending direction of column 1 is stretched, escape groove 43 can be that the structure hole 12 of column 1 is stepped down, and ensure
The structure hole 12 of column 1 can be used normally；In the present embodiment, escape groove 43 is U-type groove, easy to process, in other implementations
