Embodiment
[0024] Example: A low-voltage cable branch box, the structure of which is as Figure 1-4 As shown, a box body 2 is included. The top of the box body 2 is fixedly connected with a box cap 1, and the bottom of the box body has a bottom plate 8, and there is a ventilation gap between the box body 2 and the box cap 1.
[0025] The bottom of the box body 2 is fixedly connected with the support frame 4;
[0026] A plurality of air intake holes 7 are provided on the bottom plate 8 of the box body, and a plurality of primary condensation units 5 are fixedly connected under the bottom plate 8.
[0027] Each primary condensation unit 5 includes an intermediate plate 9 fixedly connected to the bottom plate 8 of the box body at one end, and the other end of the intermediate plate 9 is hermetically connected with the V-shaped condensation groove. The V-shaped condensation groove is formed by airtightly connecting a wide condensation plate 10 and a narrow condensation plate 11. Among the two adja...

The invention relates to a low-voltage cable branch box, which belongs to the related technical field of electric equipment. It mainly includes a box body, the top of the box body is fixedly connected with a box cap, there is a ventilation gap between the box body and the box cap, the bottom of the box body is fixedly connected with the support frame; the bottom of the box body has an air inlet, and the bottom of the box body is fixedly connected with a A plurality of primary condensation units; the primary condensation unit includes an intermediate plate fixedly connected to the bottom of the box at one end, and the other end of the intermediate plate is airtightly connected with a V-shaped condensation groove; the V-shaped condensation groove is a wide condensation plate and The narrow condensation plate is airtightly connected. Among the two adjacent V-shaped condensation grooves, the wide condensation plate on one V-shaped condensation groove covers part of the narrow condensation plate on the other V-shaped condensation groove. . The invention improves the bottom structure of the box body, thereby changing the air flow circulation inside and outside the box body, and has a drying function, and basically solves the problems of condensation and condensation dripping in the branch box.
Description
Technical field [0001] The present invention relates to the technical field related to power equipment, in particular to a low-voltage cable branch box. Background technique [0002] The number of low-voltage cable branch boxes in the station area has been increasing year by year. Due to the strong sealing of the branch boxes, the steam cannot be dissipated to the outside of the box, resulting in serious condensation inside the branch boxes and frequent failures of the low-voltage cable branch boxes, which seriously affects the stability of low-voltage lines. Evaluation indicators for performance and faults in the distribution station area. [0003] In the prior art, there have been some studies on the anti-condensation branch box, but the anti-condensation effect is not very satisfactory. Because of the transformation of existing anti-condensation equipment, it is more common to increase the height of the box cap, which makes the closed branch box semi-open. This structure can c...
