The following further describes embodiments of the present invention with reference to the drawings.
In the embodiment of the frame for a circuit breaker of the present invention, as shown in fig. 1 to 3, the frame for a circuit breaker includes a base 10, and an installation space is provided in the base 10, and the installation space can be used for placing a transmission spindle therein. Three placing positions are arranged on the base 10 and used for installing the solid-sealed polar pole. An operating mechanism protective frame is also mounted on the base 10. The operating mechanism protective frame comprises an integrated frame and a panel, and the integrated frame, the panel and the base together form an accommodating space capable of accommodating the operating mechanism.
The integrated frame is formed by bending a base plate for multiple times, wherein the base plate comprises a back plate area 11, a left side plate area 12 positioned on the left side of the back plate area 11, a right side plate area 13 positioned on the right side of the back plate area 11, and a top plate area 14 positioned on the upper side of the back plate area 11, and a chamfer area 15 is also arranged between the back plate area 11 and the top plate area 14. Triangular gaps are formed in the left side plate area 12 and the right side plate area 13, so that the left side plate area and the right side plate area can form a chamfer of the integrated frame together with the chamfer area 15 after being bent. Base connecting side areas 16 are arranged at the left end and the right end below the back plate area 11 and below the left side plate area and the right side plate area. A vertical flanging area 17 is also arranged above the top plate area 14, a plurality of threading fixing holes 19 are arranged on the vertical flanging area 17, and a through groove 18 is also arranged on the top plate area 14. In this embodiment, the side plate regions are provided on the left and right sides with the back plate region 11 as the center, and the top plate region is provided above, so that the subsequent welding work can be reduced to the maximum extent, and the length of the weld can be minimized.
The base plate is bent along the set line shown in fig. 1, namely, the left side plate area 12 is folded rightwards, the right side plate area 13 is folded leftwards, the top plate area 14 is folded downwards, the base connecting edge area 16 and the vertical flanging area 17 are folded, namely, the integrated frame shown in fig. 2 is formed, the back plate area 11 forms the back plate 1, the left side plate area 12 and the right side plate area 13 respectively form the left side plate 2 and the right side plate 3, the top plate area 14 forms the top plate 4, and the top plate 4 and the intersected parts of the left side plate and the right side plate are welded and fixed. The base connecting edge region 16 is folded over as the base connecting edge 6.
The vertical flanging area 17 is bent downwards to form a vertical flanging 7, a plurality of threading fixing holes 19 are formed in the vertical flanging 7, and the threading fixing holes 19 can enable the binding belt to penetrate through and fix the secondary wiring harness inside the frame on the frame. And the through groove 18 on the top plate 4 can be used for allowing an external vertical secondary wiring harness to extend into the through groove 18 from front to back.
As is apparent from fig. 2, the length of the top plate 4 in the front-back direction is smaller than the length of the left side plate 2 and the right side plate 3 in the front-back direction, so that the vertical position of the through groove 18 is closer to the wiring part of the operating mechanism, when the vertical secondary wiring harness passes through and is bent in the operating mechanism protective frame in the front-back direction and the left-right direction, the bending degree and the bending length in the front-back direction can be reduced, and the situation that the secondary wiring harness is bent too much to cause the complex routing of the secondary wiring harness and occupy the space in the operating mechanism protective frame is avoided.
The vertical flanging 7 is arranged on the top plate 4, the threading fixing hole 19 is formed in the vertical flanging 7, and the secondary wiring harness is fixed on the vertical flanging 7 of the frame by means of the binding action of the binding belt, so that disorder of the secondary wiring harness in the frame is avoided. And then the panel is arranged on the integrated frame, so that the threading fixing holes 19 cannot leak outwards, the sealing performance of the frame is ensured, and the protection grade is improved.
A chamfer 5 is arranged between the top plate 4 and the back plate 1, so that the possibility of point discharge during power frequency withstand voltage test can be reduced. Hoisting holes, outer side sealing plate mounting holes, component mounting holes and wire harness fixing holes are formed in the left side plate and the right side plate. The top plate is provided with a wire harness hole and a wire harness fixing hole. And horizontally bending the base connecting edges on the left and right side plates inwards. The panel connecting edge on the top plate is vertically bent downwards. When in use, the welding part 8 is welded, and the top plate 4 and the two side plates are assembled into a whole.
During the equipment, with base on the left and right curb plate on the integral type frame connect limit 6 and the base on the backplate connect limit 6 fixed connection on the base, the connected mode is for linking to each other through the bolt. There are 6 connecting parts 9. The split connection between the integrated frame and the base is realized. In other embodiments, the integrated frame may be welded to the base. And then, the panel is arranged on the integrated frame, and the integrated frame, the panel and the base are assembled to form an accommodating space capable of accommodating an operating mechanism of the circuit breaker.
In the circuit breaker, the side plate and the back plate are not required to be welded or connected through bolts, and the top plate and the side plate are welded.
As can be seen from figure 2, the notch of the through groove is arranged forwards, and the secondary wiring harness is placed into the through groove from front to back before the panel is installed, so that the problem of difficult threading caused by excessive quantity when the secondary wiring harness is threaded from top to bottom is prevented. And the secondary wiring harness is convenient to disassemble during subsequent maintenance.
In this embodiment, after the panel is mounted on the integrated frame, the panel and the through groove form a threading hole.
