Fully-sealed type low-voltage branch box

Abstract

The invention discloses a fully-sealed type low-voltage branch box which comprises a busbar frame. The fully-sealed type low-voltage branch box is characterized in that the fully-sealed type low-voltage branch box further comprises a sealed box body, a box door is formed in one side of the sealed box body, the box door is connected with the sealed box body through an embedded type rotary shaft mechanism, sealing strips are arranged between the box door and the sealed box body, the busbar frame is arranged in the sealed box body, a protective rubber layer is arranged at the outer side of the busbar frame, and a socket connected with a cable is arranged on the busbar frame. According to the fully-sealed type low-voltage branch box, the problems that an open busbar is adopted by a low-voltage branch box in the prior art, the existing low-voltage branch box is low in protective level, a line short circuit occurs when the existing low-voltage branch box is exposed to heavy rain or immersed in flood, certain economic losses are caused for a user, and the existing low-voltage branch box can not be used conveniently by the user due to the fact that power is off are solved, the structure is simple, double-layer sealing protection is adopted, and the short circuit is prevented from occurring when the line is exposed to water.

Description

technical field [0001] The invention belongs to the field of power cable accessories, in particular to a fully sealed low-voltage branch box. Background technique [0002] With the development of the distribution network cable process, when the distribution of independent loads with small capacity is relatively concentrated, the cable branch box can be used to connect multiple branches of the cable. The main function of the cable branch box is to branch or transfer the cables. The main incoming line of the branch box is connected to the low-voltage outlet terminal of the transformer or box transformer, and the outgoing lines of the low-voltage branch box are respectively connected to the low-voltage users or low-voltage electrical equipment. At present, the low-voltage branch boxes in the market all use open busbars (without sealing measures), and the protection level of the branch box itself is low. Caused certain economic loss to the user, also can bring the inconvenience...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the medium and low-voltage branch boxes in the prior art all adopt open busbars, and the protection level of the branch box itself is low, when it encounters a large amount of rainwater or flooding, it will cause short-circuiting of the line, which not only causes harm to users A certain economic loss will be caused, and it will also cause inconvenience to users due to power outages.
