The utility model discloses under the condition that does not increase panel thickness, through the change of structure, increase the intensity and the rigidity of cubical switchboard cabinet door, change planar structure in the past and be three-dimensional convex surface structure, thoroughly eliminate the cabinet door and warp, open the defect of rocking.
Description
Technical Field
The utility model relates to a switch cabinet door, especially a high-tension switchgear cabinet door belongs to the innovation technique of high-tension switchgear cabinet door.
Background
At present, most domestic high-voltage switch cabinet doors adopt a structure that the overall four-side folded edge of the cabinet door is a plane, and the cabinet door has the defect that the hidden danger of door opening shaking and deformation cannot be thoroughly solved only by increasing the plate thickness and inner reinforcement of the door because the forming size of a KYN61-40.5 front door is wide multiplied by height =1330 multiplied by 1780, and the use requirement of a user is difficult to meet.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to consider above-mentioned problem and provide a high tension switchgear cabinet door. The utility model discloses under the condition that does not increase panel thickness, through the change of structure, increase the intensity and the rigidity of cubical switchboard cabinet door, change planar structure in the past and be three-dimensional convex surface structure, thoroughly eliminate the cabinet door and warp, open the defect of rocking.
The technical scheme of the utility model is that: the utility model discloses a high tension switchgear cabinet door, the cabinet door wholly is equipped with double-folded edge inner buckling groove all around, and the left and right sides of cabinet door is equipped with 2 and rolls over the muscle.
The utility model discloses under the condition that does not increase panel thickness, through the change of structure, increase the intensity and the rigidity of switch cabinet door, change planar structure in the past and be three-dimensional convex surface structure, thoroughly eliminate the cabinet door and warp, open the defect of rocking, the utility model relates to a design benefit, convenient and practical's high tension switchgear cabinet door.

Detailed Description
Example (b):
the utility model discloses a structural schematic diagram is shown in fig. 1, the utility model discloses a high tension switchgear cabinet door, the cabinet door wholly is equipped with catching groove 1 in the double folds all around, and the left and right sides of cabinet door 4 is equipped with 2 and rolls over muscle 2.
The bottom of the back of the cabinet door 4 is provided with a grounding copper bolt 3. In this embodiment, the grounding copper bolt 3 is an M5 × 30 copper stud, and is welded to the lower left corner of the bottom of the back face of the cabinet door 4 by using a stud welding machine, so that the grounding copper bolt 3 realizes electric shock protection and circuit protection.
The cabinet door 4 is made of cold-rolled steel plates. In this embodiment, the cabinet door 4 is made of a 2.0 cold-rolled steel plate, and is punched and trimmed by using existing equipment.
In addition, four corners of the cabinet door 4 are provided with engaging joints 5. In this embodiment, the engagement lap joint 5 is repaired by sealing and filing.
In this embodiment, the cabinet door 4 is provided with a simulated bus bar installation hole 6. The cabinet door 4 is provided with an operation indication board mounting hole 7.
In this embodiment, the cabinet door 4 is subjected to electrostatic spraying after the surface treatment. The electrostatic spraying is a spraying method which utilizes a high-voltage electrostatic electric field to make paint particles with negative electricity directionally move along the opposite direction of the electric field and adsorb the paint particles on the surface of a workpiece, and the adopted epoxy powder paint has high chemical corrosion resistance and good electrical insulation performance and is widely used for the corrosion prevention of various devices and pipelines and the insulation resistance coating of the shells of motor and electrical appliances.
The utility model discloses utilize the excellent machining capacity of numerical control bender, will in the past cabinet door 4 hem all around changes into cabinet door 4 and detains curved groove in being equipped with the double folds all around, increases gate bulk strength. In addition, change the cabinet door 4 plane into the convex surface, respectively increase 2 times and roll over the muscle about cabinet door 4, greatly strengthen the rigidity of door. In addition, the switch cabinet door 4 is changed from a plane type to a three-dimensional type, and on the premise of not reducing the use performance and safety, the switch cabinet door 4 is in the three-dimensional type, so that the overall attractiveness is greatly improved. Meanwhile, the copper bolt is welded at a proper position on the left lower side of the cabinet door 4, so that the electric shock protection and the integrity of a protection circuit are improved.
The utility model meets the requirements of 5.102.2 clauses in the product standard GB/T3906-2006 on 'cover plate and door'; and for reference, if the cover plate, the door, the shielding plate and other parts are provided with electric appliances with voltage values of more than 50V exceeding the ultra-low voltage limit value, measures are taken to ensure the requirements of electric shock protection and circuit integrity, and the grounding copper bolt is welded, so that the integrity of the electric shock protection and the circuit protection is improved, and the safety of operators is further ensured.
The utility model discloses under the condition that does not increase panel thickness, through the change of structure, increase the intensity and the rigidity of switch cabinet door 4, the change is planar structure in the past for three-dimensional convex surface structure, thoroughly eliminates cabinet door 4 and warp, opens the defect of rocking.
