Abstract
The utility model discloses a kind of contact box for switch cabinet mounting structure, this contact box mounting structure comprises body and is evenly opened in the some contact box installing holes on body, and contact box installing hole adopts irregularly-shaped hole.Wherein, the shape of irregularly-shaped hole is quadrangle and four of this quadrangle rounding of angle angles, body offers two rows and amounts to six contact box installing holes.The utility model, for big current product, provides a kind of contact box for switch cabinet mounting structure, and its contact box installing hole adopts irregularly-shaped hole, fills after can making contact box, and the electric field that before avoiding, during dress, mounting screw causes is uneven.In addition, contact box mounting structure irregularly-shaped hole is of value to the installation of contact box, ensures degree of protection and the insulating requirements of switch cubicle simultaneously.
Description
Technical field:
The utility model belongs to switch cubicle and manufactures field, particularly a kind of contact box for switch cabinet mounting structure.
Background technology:
Existing contact box mounting structure all adopts cold-rolled steel sheet, galvanized steel plain sheet or corrosion resistant plate, and in the way of alternate fluting.When contact box front is installed, go ahead from rear cabinet when namely contact box is installed, by screw, contact box is fixed at front cabinet.At this moment, mounting screw from high-pressure conductor distance very close to, easily produce insulation fault.
Especially when the current increases, contact arm diameter increases, in order to solve Insulation Problems, when filling after employing contact box, namely wear from front to back when contact box is installed, need the via hole through contact box mounting structure, because the line outlet of contact box is larger, in order to install the degree of protection that will ensure switch cubicle smoothly simultaneously, on contact box mounting structure, the diameter dimension design of via hole brings certain restriction.
Utility model content:
The purpose of this utility model is to effectively change above shortcoming, being emulated by electric Field Calculation, provides a kind of contact box for switch cabinet mounting structure, and it adopts rear dress to install contact box, effectively solves protection and the Insulation Problems of above-mentioned installation.
For achieving the above object, the utility model adopts following technical scheme to be achieved:
A kind of contact box for switch cabinet mounting structure, this contact box mounting structure comprises body and is evenly opened in the some contact box installing holes on body, and contact box installing hole adopts irregularly-shaped hole.
The utility model further improves and is, the shape of irregularly-shaped hole is quadrangle and four of this quadrangle rounding of angle angles.
The utility model further improves and is, body offers two rows and amounts to six contact box installing holes.
The utility model further improves and is, the circumference of each contact box installing hole offers some flange mounting holes, during using state, contact box is through contact box installing hole (302) upside-down mounting, and contact box is fixed on contact box mounting structure by flange mounting hole.
The utility model further improves and is, body adopts cold-rolled steel sheet, galvanized steel plain sheet or corrosion resistant plate to make.
The utility model further improves and is, the rectangular shape of body, and its surrounding is curling shape.
Relative to prior art, the utility model has following beneficial effect:
1, the utility model is when filling after ensureing contact box, makes easy for installation.
2, the irregularly-shaped hole of contact box mounting structure ensures degree of protection and the insulating requirements of switch cubicle.
In sum, the utility model, for big current product, provides a kind of contact box for switch cabinet mounting structure, and its contact box installing hole adopts irregularly-shaped hole, fills after can making contact box, and the electric field that before avoiding, during dress, mounting screw causes is uneven.In addition, contact box mounting structure irregularly-shaped hole is of value to the installation of contact box, ensures degree of protection and the insulating requirements of switch cubicle simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of contact box for switch cabinet mounting structure of the utility model;
Fig. 2 is scheme of installation of the present utility model;
Fig. 3 is the contact box mounting structure structure chart with irregularly-shaped hole.
In figure: 1, contact box; 2, contact arm; 3, contact box mounting structure; 11, contact box line outlet; 12, full skirt; 13, mounting flange; 301, body; 302, contact box installing hole; 303, flange mounting hole.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of contact box for switch cabinet mounting structure of the utility model, this contact box mounting structure 3 comprises body 301 and is evenly opened in the some contact box installing holes 302 on body 301, and contact box installing hole 302 adopts irregularly-shaped hole.Wherein, the shape of irregularly-shaped hole is quadrangle and four of this quadrangle rounding of angle angles, body 301 offers two rows and amounts to six contact box installing holes 302.
In addition, the circumference of each contact box installing hole 302 offers some flange mounting holes 303.
Further, body 301 adopts cold-rolled steel sheet, galvanized steel plain sheet or corrosion resistant plate to make, and the rectangular shape of body 301, its surrounding is curling shape.
Further, the profiled holes that specific embodiments adopts adopts quadrangle and four of this quadrangle rounding of angle angles, and the utility model does not limit to therewith, as slotted eye, polygonal hole etc. all belong within the utility model protection range.
During work, contact box 1 through contact box installing hole 302, utilizes the inserts screwed hole on mounting flange 13 to be fixed on contact box mounting structure 3 by contact box 1 from front to back.Shown in detailed in accompanying drawing 2, Reference numeral 11 is contact box line outlet, and because contact box line outlet 11 is comparatively large, in order to ensure that contact box 1 is installed smoothly, contact box installing hole 301 diameter on contact box mounting structure 3 is large.By contact box 1 through contact box mounting structure 3, be fixed on contact box mounting structure 3 by mounting flange 13.For ease of the installation of contact box 1, the contact box installing hole 301 of contact box mounting structure 3 is strengthened as much as possible, will ensure the degree of protection of switch cubicle, what the utility model was innovated devises a kind of contact box mounting structure with irregularly-shaped hole, thus reduces the installation difficulty of contact box 1 simultaneously.Ideal through electric Field Calculation result.And complete Insulation Test in factory, demonstrate the reasonability of this design.
