Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an anti-static device for power distribution cabinets. Background Technology
[0002] During use, power distribution cabinets may generate static electricity due to factors such as material friction, environmental humidity, and poor equipment grounding. An existing patent (publication number: CN220421122U) discloses an anti-static component for power distribution cabinets. This invention suppresses static electricity generation inside the cabinet by using an insulating film and an anti-static nylon plate. Simultaneously, the generated static electricity is transferred to a grounded lead wire via connecting bolts, further eliminating static electricity inside the cabinet and achieving a good anti-static effect. However, in practical applications, because the nylon partition is located outside the anti-static nylon plate and the fixed support plate, and is connected to the fixed support plate via bolts, maintenance on the equipment on the fixed support plate requires first removing the nylon partition to expose the equipment. After maintenance, the nylon partition must be reinstalled, making the process cumbersome, time-consuming, and labor-intensive. Therefore, we propose an anti-static device for power distribution cabinets. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides an anti-static device for power distribution cabinets.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] Design an anti-static device for a power distribution cabinet, including a cabinet body with a hinged door, the inner wall of the cabinet being covered with a conductive film, a fixed support plate being assembled and connected inside the cabinet, an isolation mechanism being provided on the side of the fixed support plate near the cabinet door, the isolation mechanism including symmetrically arranged insulating brackets, insulating baffles being hinged on the insulating brackets, adjacent insulating baffles being spliced together, and handles being installed on the insulating baffles, an anti-static elimination mechanism being provided below the fixed support plate, the anti-static elimination mechanism including an ion fan with an upward air outlet, a copper busbar being connected to the inner wall of the bottom of the cabinet body, an electrical connection piece being connected to the inner side of the cabinet door and overlapping with the copper busbar, and a grounding component being provided on the rear side of the cabinet body.
[0006] In the above scheme, the inner wall of the cabinet is fixed with a mounting base that is connected to the insulating bracket.
[0007] In the above scheme, a limiting plate that connects to the inner wall of the cabinet is provided between the insulating bracket and the fixed support plate. The limiting plate is an insulating limiting plate, and an installation port that cooperates with the fixed support plate is opened on the limiting plate.
[0008] In the above solution, the static electricity elimination mechanism includes a base installed on the inner wall of the bottom of the cabinet, the ion fan is detachably connected to the top of the base, the bottom of the base is detachably connected to a filter screen communicating with the air inlet of the ion fan, the filter screen moves through the bottom of the cabinet, and the top of the cabinet has a ventilation opening.
[0009] In the above solution, mounting grooves are provided on both the upper and lower sides of the base. An assembly plate is magnetically connected to the inner wall of the upper mounting groove. The ion fan is installed on the assembly plate, and an air outlet is provided on the assembly plate. The filter is magnetically connected to the inner wall of the lower mounting groove, and a control rod is installed at the front end of the filter.
[0010] In the above scheme, the assembly plate is a magnetic metal assembly plate, the frame of the filter screen is magnetic metal, and the inner wall of the mounting groove is embedded with a magnetic block.
[0011] In the above solution, a dust cover fixed to the top of the cabinet is provided above the ventilation opening, and a guide plate parallel to the width direction of the cabinet is fixed to the inner wall of the top of the dust cover.
[0012] In the above scheme, the grounding component includes a metal screw threadedly connected to a copper busbar, an annular groove is provided on the metal screw, a lead wire is wound around the inner wall of the annular groove, and a nut is connected to the end of the metal screw.
[0013] The advantages and beneficial effects of this utility model are as follows: By setting a fixed support plate and an isolation mechanism, the equipment is installed using the fixed support plate, and the equipment is isolated inside the cabinet by using an insulating baffle hinged to the insulating bracket. Compared with the prior art, this not only uses the insulating baffle to suppress the equipment from discharging outward, but also eliminates the need to disassemble the insulating baffle. Simply rotating the insulating baffle exposes the equipment for later maintenance, saving time and effort. By setting a conductive film, copper busbar, electrical connection piece, and grounding component, a discharge circuit is formed using the conductive film, copper busbar, electrical connection piece, metal screw, and lead wire. The charge accumulated on the cabinet and cabinet door is released to the ground through the lead wire, thereby eliminating static electricity. By setting a static elimination mechanism, when the ion fan outputs airflow upward, the positive and negative ions in the airflow are transported to the surface of charged objects to neutralize the charge, thereby achieving the effect of eliminating static electricity.
