The central controller is connected to the LCD display screen, keyboard, feeder air switch, AC air switch, and charging control module through wires respectively; the power input terminal of the charging control module is connected to a storage battery; this utility model is applied to DC emergency power supplies.

[0003] The backup DC emergency power supply device in the aforementioned patent has the advantage of simple structure, but its cabinet is not equipped with a protection mechanism for anti-static purposes. Since the cabinet contains mostly electronic components, which are highly sensitive to static electricity, when a hand carrying static electricity touches the cabinet, it can easily damage the components inside the cabinet. Utility Model Content

[0004] In order to overcome the problem that traditional DC emergency power supply devices in the prior art do not have anti-static devices, which makes them prone to damage caused by static electricity during use, this utility model provides a DC emergency power supply EPS device cabinet with anti-static function.

[0005] This utility model discloses a DC emergency power supply EPS device cabinet, including a cabinet, a movable door connected to a hinge on one side of the cabinet, a wiring terminal installation area for connecting power supply and load on the movable door, a rectifier assembly installation area for use with the wiring terminal installation area on the cabinet, a battery pack installation area inside the cabinet, and an anti-static layer coated on the surface of the cabinet and the surface of the movable door.

[0006] Preferably, the rectifier assembly installation area is located on the front face of the cabinet above the movable door, and a heat dissipation plate is provided between the rectifier assembly installation area and the movable door.

[0007] Preferably, the longitudinal section of the rectifier assembly mounting area is rectangular, and several evenly distributed partitions are vertically welded within the rectifier assembly mounting area.

[0008] Preferably, the heat sink has several evenly distributed, elongated heat dissipation holes on its front side.

[0009] Preferably, a central control mounting position for installing a touch screen is provided on the movable door above the terminal block mounting area, and indicator light mounting positions for installing indicator lights are provided on the left and right sides of the central control mounting position, respectively. A circuit breaker mounting position for installing a circuit breaker is provided on the movable door below the terminal block mounting area.

[0010] Preferably, the battery pack installation area is located at the bottom of the cabinet, and an insulating plate is inserted into the housing between the battery pack installation area and the movable door.

[0011] The antistatic layer is applied by electrostatic spraying of epoxy resin powder, which is uniformly applied to the surface of the cabinet and the surface of the movable door.

[0012] This utility model is mainly used in workplaces with limited on-site installation conditions and high levels of contamination. The cabinet integrates mounting positions for various electrical components such as rectifiers, battery packs, touchscreens, and terminal blocks. The cabinet frame can be made of high-quality aluminum-zinc coated steel, and the outer shell can be made of high-quality cold-rolled steel. All outer frames, partitions, and functional unit mounting plates are electrostatically sprayed with epoxy resin powder to ensure corrosion resistance. The cabinet structure can also be arranged in a single row against a wall, with front-mounted maintenance, bottom-entry and bottom-outlet wiring, and ventilation holes on the front and sides. A replaceable dust filter can also be installed outside the heat dissipation plate. Exposed conductor components such as the cabinet bottom plate, frame, and metal shell are directly and effectively connected to each other, or through effective connections made by protective conductors to ensure the continuity of the protection circuit. The cabinet door is opened flexibly via hinges, and the fastening connection is firm and reliable. This utility model is both aesthetically pleasing and practical, while also meeting the requirements of safety and ease of operation.

[0013] This utility model has the following advantages: it has anti-static function, simple structure, and convenient installation. Attached Figure Description
