Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box for electric power equipment used for safe production. Background Art

[0002] The distribution box is a low-voltage distribution box that is composed of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. It is commonly used in various factories, buildings, and substations. At present, the application field of distribution boxes is becoming wider and wider, and has gradually expanded from indoors to outdoors. In addition to requiring a certain wall thickness to ensure its strength, outdoor distribution boxes also need to have certain heat dissipation performance. Since switchgear, instruments, protective circuits and auxiliary equipment are all installed in a closed distribution box, a large amount of heat will be generated during operation. The lack of air circulation in the distribution box will cause the temperature in the box to be too high, which may easily cause short circuits in electrical components, fires and burn electrical equipment, thereby causing damage to electrical appliances in the distribution box and reducing the safety of the distribution box.

[0003] A Chinese patent discloses a distribution box for electric power equipment for safe production, announcement number: CN217903798U, comprising a base, the four corners of the lower surface of the base are fixedly connected to support seats, the upper surface of the base is fixedly connected to a distribution box, the inner rear side wall of the distribution box is fixedly connected to a heat-absorbing copper block, the front of the distribution box is provided with a door panel, the outer side of the door panel is fixedly connected to a handle, and the left and right sides of the distribution box are provided with dust-proof filtering devices.

[0004] In the prior art, heat dissipation is performed physically inside the distribution box by setting up heat dissipation strips. However, the heat dissipation strips are directly exposed to the air, which may cause damage to the heat dissipation strips when bumped. In addition, the distribution box is prone to moisture during long-term use, which affects the overall service life of the distribution box. For this reason, we propose a distribution box for power equipment for safe production. Utility Model Content

[0025] The effect achieved by the entire embodiment 1 is that the air intake fan 204 is started to allow external air flow to enter the interior of the chassis 1, which can drive the internal heat to flow outward. At the same time, the filter 202 can filter the dust in the air flow, so that the dust stays on the filter 202. The back panel 201 is provided with a heat dissipation strip 209 to absorb the heat generated by the chassis 1. When the heat dissipation strip 209 needs to be inspected, the protective door 4 is opened, and the heat dissipation strip 209 can be inspected at this time. The dehumidification bag 208 can absorb the moisture generated inside the chassis 1, thereby increasing the overall service life of the device.

[0026] Embodiment 2, as Figure 1-5 As shown, a protective box 3 is provided on the surface of the back panel 201, a protective door 4 is hinged on the surface of the protective box 3 through a hinge, a heat dissipation hole 5 is provided on the surface of the protective door 4, a lock is provided on the surface of the protective door 4, a threaded bolt is provided on the surface of the positioning pipe 207, and the threaded bolt is threadedly connected to the chassis 1, a plurality of air outlets 6 are provided on both sides, the top and the back panel 201 of the outer surface of the chassis 1, a partition 7 is provided on the surface of the chassis 1, a box door 8 is hinged on the surface of the chassis 1 through a hinge, and a dust removal hole 9 is provided on the lower surface of the air inlet duct 203.
