Description

Technical Field

[0001] This utility model relates to the field of power cabinet equipment technology, specifically, it demonstrates a vibration-resistant shielded power cabinet structure. Background Technology

[0002] A power supply cabinet is a set of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, and should not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switches.

[0003] Currently, there are various types of power cabinets on the market, but most of these power cabinets have simple structures and their internal structural layout is not well organized, resulting in a messy layout of internal components and circuits. Moreover, they have poor resistance to electromagnetic interference and do not have the function of shock absorption. Utility Model Content

[0004] The purpose of this invention is to provide a vibration-resistant shielded power cabinet structure that is simple and practical, and has good vibration resistance and shielding effects.

[0005] The technical solution is as follows:

[0006] A vibration-resistant shielded power cabinet structure includes a cabinet body, the cabinet body being hollow and divided into an upper and lower section. The front side of the cabinet body has upper and lower openings corresponding to the upper and lower sections, respectively. The upper and lower sides of the cabinet body are hinged to an upper door panel and a lower door panel, respectively used to close the upper and lower openings on the front side of the cabinet body. Shielding structures are provided between the upper door panel and the cabinet body, and between the lower door panel and the cabinet body. A heat dissipation plate is provided on the back of the cabinet body.

[0007] The cabinet has shielded waveguide windows installed on both the upper and lower sides of its inner walls. The two upper shielded waveguide windows are also connected to cooling fans. The side surface of the cabinet also has several ventilation slots arranged in an upper and lower array to cooperate with the shielded waveguide windows. A partition is installed in the lower part of the lower area of ​​the cabinet. There is a gap between the partition and the bottom plate of the cabinet. There are openings in the middle of the partition and the middle of the bottom plate of the cabinet. Several first vibration isolators are installed on both sides between the partition and the bottom plate of the cabinet.

[0008] Furthermore, the outer wall of the cabinet is provided with air guide plates corresponding to the ventilation slots. The upper part and both sides of the air guide plates are connected to the upper end and both sides of the ventilation slots, and the lower part of the air guide plates is open with a gap between them and the outer wall of the cabinet. The air guide plates change the direction of the airflow from the ventilation slots, preventing the airflow from flowing randomly and back into the cabinet.

[0009] Furthermore, the shielding structure includes a bent flange and a U-shaped groove. The bent flange is located on the outer periphery of the upper and lower openings on the front side of the cabinet. The U-shaped groove is located on the inner wall of the upper and lower door panels. The U-shaped groove accommodates the bent flange, and a shielding strip is also installed within the U-shaped groove. After the upper or lower door panel is closed, the cooperation between the U-shaped groove and the bent flange improves the sealing effect of the equipment. The shielding strip within the U-shaped groove further enhances the shielding effect.

[0010] Furthermore, the upper and lower door panels are respectively bent inwards vertically around their perimeters to form upper and lower shielding folds. This effectively prevents dust and rainwater from entering the cabinet, meeting dustproof and waterproof protection requirements.

[0011] Furthermore, pneumatic springs are installed between the upper door panel and the cabinet body, and between the lower door panel and the cabinet body. In this way, the pneumatic springs provide support, cushioning, braking, and angle adjustment between the upper door panel (or lower door panel) and the cabinet body, facilitating the opening and closing of the upper door panel (or lower door panel) by staff. Moreover, based on the characteristics of the pneumatic springs, after opening the upper door panel (or lower door panel), it can be easily rotated and fixed at any angle, facilitating subsequent operation and maintenance.

[0012] Furthermore, the top of the cabinet is equipped with two shock absorber mounting brackets, and a back shock absorber mounting plate is vertically mounted on the outside of the shock absorber mounting brackets via a second vibration isolator. This can reduce vibration and improve the stability and reliability of the power cabinet.

[0013] Furthermore, the shock absorber mounting bracket is also equipped with lifting rings for suspending the power cabinet accessories, facilitating the processing, installation, maintenance, and replacement of equipment.

[0014] Furthermore, a horizontal handrail is provided in the middle of the front side of the cabinet. The handrail is located between the upper and lower door panels, and it provides an additional support point to help users maintain their balance when operating the power cabinet, reducing the risk of falls and effectively preventing accidents.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by dividing the cabinet interior into an upper and lower area, with most components installed in the upper area and wiring arranged in the lower area, the internal layout of the cabinet becomes more organized. Furthermore, the combination of shielded waveguide windows, ventilation slots, and cooling fans improves the cabinet's heat dissipation, ventilation, and interference shielding performance. The first vibration isolator installed at the bottom of the cabinet absorbs and mitigates the impact of vibration on the cabinet, effectively improving the stability and reliability of the power cabinet, thereby reducing the failure rate of internal components and extending the service life of the equipment.
