[0002] The design life of the high-voltage electrical box of a high-speed train or a motor vehicle is 30 years. It adopts a two-meter square box structure, which is full of high-voltage electrical devices. Since the locomotive is inevitably subject to bumps and vibrations during operation, the foundation parts of each mounting seat (such as steel plates, steel sections, etc.) will crack, break, and open welds over time, which directly affects the safety of the high-speed train or motor vehicle operation, or brings safety hazards to the locomotive operation. Therefore, it is urgent to study the structure, strength, stiffness and stability of these mounting seats.

[0003] The lightning arrester mounting seat in the high-voltage electrical box currently in use is composed of a box wall and a mounting plate with a thickness of 5mm. The radius of the arc at the bending part of the mounting plate is generally 6mm. After a long period of bumpy operation, batch fractures occur at the bending part of the mounting plate, posing a great safety hazard to the stable operation of the locomotive. In the prior art, in order to increase the strength and rigidity of this part, a reinforcing rib plate is welded at the bending part of the original mounting plate. Although the problem of insufficient strength can be solved, the cost for the manufacturer is increased, and the process is changed from general management to special management. Now, a simpler improvement method is urgently needed, which can meet the strength and rigidity requirements of the installation base without increasing the manufacturing cost and bringing other disadvantages to the manufacturer. Therefore, the present application provides a lightning arrester mounting seat for a high-voltage electrical box to meet the demand. Utility Model Content

Although it can solve the problem of insufficient strength, it increases the cost for the manufacturer and changes the process from general management to special management.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A high-voltage electrical box lightning arrester mounting base comprises a box wall, an inner wall of which is mounted a mounting plate, the mounting plate being provided with a first folded angle and a second folded angle, the mounting plate being 6 mm thick, and the arc radii of the first folded angle and the second folded angle being 10 mm.

[0007] Preferably, two pads are welded to the inner wall of the box body, and both ends of the mounting plate are welded to the pads respectively, and the throat thickness of the fillet weld is 5 mm.

[0008] Preferably, a left groove is provided at the first folded corner on one side of the mounting plate close to the inner wall of the box wall.

[0009] Preferably, the mounting plate is provided with a left reinforcing rib on the opposite side of the left groove.

[0010] Preferably, a right groove is formed at the second corner on one side of the mounting plate close to the inner wall of the box wall.

[0011] Preferably, the mounting plate is provided with a right reinforcing rib on the opposite side of the right groove.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] In the above scheme, by setting a mounting plate and increasing the thickness of the mounting plate, before installing the required mounting plate, a bending machine is used to press the mounting plate to form a first corner and a second corner with an arc radius of 10mm, and at the same time, a left groove and a right groove can also be directly pressed and folded, and the left groove and the right groove also form a left reinforcing rib and a right reinforcing rib on the opposite side of the mounting plate, and then the two pads are welded to the box wall and then the two ends of the mounting plate are welded to the pads respectively. During welding, the throat thickness of the fillet weld can be increased to 5mm according to the shape to further enhance the stability of the connection. The advantage of this is that the new structure is simple, easy to weld, and easy to manufacture. Moreover, for the entire high-voltage box, the manufacturing cost is reduced after the structure is improved. There is almost no change, no additional cost is added, the thickness of the mounting plate is increased, the strength and rigidity are also greatly improved, and the arc radius of the first corner and the second corner is increased to 10mm, which is convenient for single plate bending construction, increases strength, and reduces stress at the bending point. The anti-break ability is significantly enhanced. By setting left and right reinforcing ribs, the left and right reinforcing ribs can be directly pressed out while bending the mounting plate, without adding additional cost to the external reinforcing rib plate, so that the first corner and the second corner can withstand more force and become more stable, further solving the problem of insufficient strength, eliminating the safety hazard of the lightning arrester mounting seat, and providing reliable technical guarantee for the safe operation of the locomotive.
