Description

Technical Field

[0001] The invention relates to the field of cabinets, in particular to a detachable uninterruptible power supply cabinet. Background Art

[0002] UPS, or uninterruptible power supply, is a constant voltage and frequency uninterruptible power supply with energy storage device and inverter as the main component. Industrial frequency UPS power supply is widely used in billing centers, communication base stations, bank outlets, ATM automatic teller machines, securities, transportation, electricity, industry and other industries network office environments. The latest industrial frequency machine adopts the most advanced DSP digital control technology in the world, with voice alarm function, high-speed microprocessor (MCU), programmable logic device (CPLD), sixth-generation low-loss high-power IGBT and static switch; it realizes large UPS power supply capacity, high reliability and stable performance.

[0003] The side panels of the existing integrated cabinets are fixed by welding, which is not convenient for disassembly. When the electrical components inside the cabinet fail, the staff can only open the maintenance door and repair the electrical components in the cabinet from one side of the maintenance door. However, for cabinets with large sizes and deep vertical and horizontal dimensions, it is inconvenient to repair only through one side of the maintenance door, resulting in low maintenance efficiency and great difficulty in operation. Summary of the invention

[0004] In order to facilitate the maintenance of electrical components in a cabinet and improve maintenance efficiency, the present invention provides a detachable uninterruptible power supply cabinet.

[0005] The present invention provides a detachable uninterruptible power supply cabinet adopts the following technical solution:

[0006] A detachable uninterruptible power supply cabinet comprises a base, four corners of the top of the base are provided with vertically arranged connecting rods, a top plate is fixedly provided on the top of the connecting rods, an inspection door is hinged on one side of the top of the base, side panels are arranged on both sides of the base perpendicular to the inspection door, and a back panel is bolted to the side of the base away from the inspection door; the side panels comprise an upper side panel and a lower side panel, the top of the upper side panel is hinged to the top panel, the bottom of the upper side panel is bolted to the connecting rod, and the lower side panel is detachably connected to the connecting rod.

[0007] By adopting the above technical solution, when it is necessary to inspect and repair the electrical components in the cabinet, first determine the position in the cabinet. If the component is close to the inspection door, the inspection door can be opened for inspection. If the component is close to the back panel, the back panel can be removed for inspection. If it is close to the upper side panel, the upper side panel can be flipped upward around the hinge point with the top panel. If it is close to the lower side panel, the lower side panel can be removed from the base and the connecting rod for inspection. This replaces the traditional method of only being able to inspect and repair the electrical components in the cabinet from one side of the inspection door, facilitates the inspection of the components in the cabinet, and improves maintenance efficiency.

[0008] Optionally, the side plate includes a baffle rod arranged in the middle of the connecting rod, the top of the upper side plate is rotatably connected to a rotating shaft, a slider is fixed on the rotating shaft, a storage cavity is opened in the top plate, sliding grooves are opened on two symmetrical sides of the top plate, and sliding columns slidably connected to the sliding grooves are fixed at both ends of the slider.
