Embodiment 1

[0018] Such as figure 1 , 2 As shown, a power distribution cabinet includes a rear cover 101, a top cover 102, and frames 103 arranged on both sides. A bottom plate 104 is arranged below the frame 103, and the two frames 103 are far away from the A card slot is provided at one end of the rear end cover 101, and the card slot is provided along the length direction of the frame 103. A front end cover 105 is provided on the side of the frame 103 away from the rear cover 101. The end faces on both sides in the width direction of the front end cover 105 are respectively clamped in the grooves on the frame 103, and the top cover 102 is provided with grooves 106 corresponding to the positions of the grooves. The upper end surface of the front end cover 105 is embedded inside the groove 106, a lamp holder 107 is provided on the lower end surface of the top cover 102, and a lamp group 108 is provided on the lamp holder 107. An infrared switch 109 is provided on the lower end surface of ...

Embodiment 2

[0021] In this embodiment, on the basis of Embodiment 1, in order to prevent moisture from entering the inside of the frame from the outside of the cover, in this embodiment, preferably, the cover 116 is a hollow cylindrical structure inclined downward.

[0022] In this embodiment, in order to facilitate the installation of the partition, preferably, the partition is clamped between the top cover and the bottom plate. A card slot 120 is provided on the lower end surface of the top cover 102. The card slot 120 is at least two arranged in parallel along the width direction of the top cover 102, the bottom plate 104 is provided with a positioning slot 121 corresponding to the position of the card slot 120, and the positioning slot 121 is A T-shaped groove, the upper end of the partition plate 114 is clamped in the clamping groove 120, and the lower end surface of the partition plate 114 is provided with a sliding block 122 matching the positioning groove 121, and the The sliding blo...

Embodiment 3

[0024] This embodiment is based on embodiment 1. In this embodiment, in order to enable the front end cover to be relatively fixed on the bottom plate, preferably, a positioning edge is provided below the bottom plate 104 near the front end cover 105. 123. The positioning side 123 is perpendicular to the bottom plate 104, and the side of the positioning side 123 away from the bottom plate 104 is arched toward the side away from the front end cover 105 to form a semicircular outer circumference. A sealing strip 124, a U-shaped baffle 125 is provided on the lower end of the front end cover 105, and one end of the baffle 125 away from the front end cover 105 is bent inward to form an arched sealing edge 126, so When the upper end of the front end cover 105 is clamped to the inner side of the groove 106, the arched sealing edge 126 is clamped above the sealing strip 124.

[0025] In this embodiment, by clamping the arched sealing edge above the sealing strip, the front end cover can ...

Abstract

The invention discloses a power distribution cabinet. The power distribution cabinet comprises a back end cover, a top cover and frames arranged on the two sides. A bottom plate is arranged below the frames. Clamping grooves are formed in the ends, far away from the back end cover, of the two frames and are formed in the length directions of the frames. A front end cover is arranged on the sides, far away from the back end cover, of the frames, and the two side end faces, in the width direction, of the front end cover are clamped into the clamping grooves in the frames respectively. The top cover is provided with grooves corresponding to the clamping grooves in position. The upper end face of the front end cover is embedded into the inner sides of the grooves. A lamp holder is arranged on the lower end face of the top cover, and a lamp set is arranged on the lamp holder. An infrared type switch arranged on the top cover is adopted to measure detection black points, when the detection black points are not measured, a controller drives a relay to be closed so that the lamp set can be powered, and therefore when the switch cabinet is opened, illumination can be automatically started in the switch cabinet.

Description

Technical field [0001] The invention relates to a power distribution cabinet. Background technique [0002] A lot of electrical equipment is usually installed in the power distribution cabinet. During the maintenance process, its internal operation is inconvenient, especially during night maintenance, which requires special lighting equipment, which causes maintenance inconvenience. Summary of the invention [0003] The purpose of the present invention is to provide a power distribution cabinet, which can improve the problems existing in the prior art. By adopting an infrared switch arranged on the top cover, the black point is measured and detected. When the black point is not measured, the controller The drive relay is closed to energize the lamp group, so that when the switch cabinet is opened, the lighting in the switch cabinet can be automatically started. [0004] The present invention is realized through the following technical solutions: [0005] A power distribution cabinet...
