Detailed Description

The present invention will be described in more detail with reference to the following embodiments, which are provided by way of illustration and not limitation, and the scope of the present invention should not be limited thereby.

a busbar mounting structure for an electrical cabinet comprises a mounting crossbeam 5, a busbar clamp lower support 2, a busbar clamp upper support 1, a main busbar 3, a long bolt 4 and a nut 6, wherein the mounting crossbeam 5 is of a long-strip straight plate structure, the two mounting crossbeams are arranged in parallel at intervals, the busbar clamp lower support 2 is mounted in the middle of the upper end of the mounting crossbeam on two sides, the busbar clamp upper support 1 is mounted above the busbar clamp lower support at intervals, the shapes of the busbar clamp upper support and the busbar clamp lower support are the same, and the busbar clamp upper support and the busbar clamp lower support are both of a frame structure with the middle part arched upwards,

a plurality of groups of busbar openings for fixing the main busbar are arranged between the busbar clamp upper bracket and the busbar clamp lower bracket at intervals, and the busbar openings on the two sides are arranged oppositely;

two ends of a plurality of main busbars 3 are respectively embedded and fixed in busbar openings opposite to two sides, and the main busbars of the embodiment comprise five main busbars including a three-phase alternating-current busbar, an N-line busbar and a grounding busbar;

the main bus bars are arranged in parallel at intervals and in a staggered manner, so that the shielding problem of the mounting structure is avoided, and the adjacent main bus bars are staggered in height so as to be convenient for mounting the leading-out bars; a plurality of mounting holes 9 are uniformly distributed on the main busbar at intervals, and the mounting holes can be regular screws 8 to fix the leading-out row 7.

The frame construction of this embodiment is isosceles trapezoid, penetrating screw hole about the both ends that the generating line pressed from both sides the upper bracket and the generating line pressed from both sides the lower carriage all made, a plurality of fixed orificess 10 of interval equipartition on the installation crossbeam, the screw hole of the generating line clamp upper bracket that long bolt 4 passed upper and lower correspondence in proper order, the screw hole of generating line clamp lower carriage and the fixed orifices of installation crossbeam, long bolt mounting nut 6 at installation crossbeam lower extreme fixes, the locking generating line presss from both sides the upper bracket, the generating line presss from both sides the lower carriage and installs the crossbeam, thereby the main female row of locking in step.

The upper slope of the screw hole position of the bracket 1 on the bus-bar clamp is designed with a small plane 11 so that the screw can be normally installed and fastened in the vertical direction.

The mounting steps of the structure are as follows:

at first, press from both sides the lower carriage 2 with the female row and place on the installation crossbeam 5 in the regulator cubicle, the female row presss from both sides upper bracket 1 and places in the female row presss from both sides 2 upper ends of lower carriage, make the female row press from both sides the female opening of upper bracket 1 and female row clamp lower carriage 2 and place relatively, and the female row presss from both sides upper bracket 1, the female row presss from both sides the screw hole of lower carriage 2 and the fixed orifices 10 of installation crossbeam 5 and aligns, it has a plurality of fixed orifices 10 to open according to the equidistance principle on the installation crossbeam 5, in order to make things convenient for female arranging to place in more reasonable mounted position.

The long screws 4 sequentially penetrate through the upper support 1 of the female clamp, the lower support 2 of the female clamp and the mounting cross beam 5 from top to bottom, so that the three can be relatively fixed in the horizontal direction, but can still move in the vertical direction.

At the moment, five main busbars 3 including a three-phase alternating-current busbar, an N-line busbar and a grounding busbar are sequentially arranged between the upper busbar clamp bracket 1 and the lower busbar clamp bracket 2 through busbar openings of the upper busbar clamp bracket 1 and the lower busbar clamp bracket 2, the sum of the depths of busbar openings of the upper busbar clamp bracket 1 and the lower busbar clamp bracket 2 is smaller than the width of the main busbar 3, and the widths of busbar openings of the upper busbar clamp bracket 1 and the lower busbar clamp bracket 2 are slightly larger than the thickness of the main busbar 3, so that the busbars are convenient to install and cannot be inclined.

And finally, screwing the long screw down by using a nut below the mounting cross beam to completely fasten the main bus bar.

A plurality of mounting holes of even design on the main female arranging, the mounting hole on leading out row and the main female row utilizes conventional screw fixed connection, can directly use electric tool fastening screw, when leading out row and the main female row of front side are connected, installs the fastening from the front side, when being connected with the main female row of rear side, can follow the rear side installation fastening.

Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and appended claims, and therefore, the scope of the invention is not limited to the disclosure of the embodiments and drawings.
