Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a high-voltage cable branch box. Background Art

[0002] The main function of the high-voltage cable branch box is to branch or transfer cables, which solves the problem of a large number of branches in the original distribution network overhead lines. The cable branch box uses a simple, convenient and flexible connection combination method, which allows the cable branch box to be used in many scenarios.

[0003] For example, the patent with the authorization announcement number CN219420199U discloses a multifunctional high-voltage cable branch box. It includes a main box body consisting of a lower box body with a rectangular cross-section structure and an upper box body with an isosceles trapezoidal cross-section structure. The top two sides of the main box body are respectively hinged with flip covers with an inverted triangular cross-section structure. The two sides of the lower box body are hinged with side door panels located below the flip cover. The main box body is provided with an inlet bushing and an outlet bushing. The upper box body is provided with a vacuum circuit breaker, an operating mechanism and a control panel. The control panel faces the opening direction of one of the flip covers. A supporting device is provided between the flip cover and the upper part of the upper box body.

[0004] The above patent can facilitate the operation of the components in the box and achieve a cooling effect. Before maintenance, the vacuum circuit breaker can be turned on and off directly by manually operating the operating mechanism, effectively avoiding the potential safety hazards during the maintenance process; however, the disadvantage of the above patent is that even if a rubber strip is used to seal the main box and the flip cover, as the use time increases, the rubber strip ages, and rainwater can easily enter the box from between the main box and the top of the flip cover.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
