Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and distribution control equipment, and more specifically, to a protective device for power transmission and distribution control equipment. Background Art

[0002] The concept of power transmission and distribution encompasses three aspects: transmission, transformation, and distribution. Transmission refers to the transfer of electrical energy, connecting power plants and load centers that are located far apart (up to thousands of kilometers apart), enabling the development and utilization of electrical energy beyond geographical constraints. Transformation refers to the process of using equipment to convert voltage from a low level to a high level (boosting) or from a high level to a low level. Distribution, the method of allocating electricity to users within a consumer region, directly serves users. Transmission and distribution control equipment utilizes protective devices, such as protective boxes.

[0003] Prior art, such as the invention patent application with publication number CN113851970A, discloses a protective device for power transmission and distribution control equipment. This device, through the coordinated use of an exhaust mechanism and an air intake mechanism, not only provides excellent heat dissipation, but also prevents rainwater from entering the interior of the protective box body, potentially damaging the power transmission and distribution control equipment within the protective box body. This device is relatively practical. This prior art addresses the technical problem of preventing rainwater from entering the protective box. However, power transmission equipment not only needs to be protected from rainwater but also, more importantly, needs to achieve electrical isolation, shielding, and leakage protection. Therefore, the present invention provides a protective device for power transmission and distribution control equipment that provides both rain protection and electrical isolation.

A closable door 3 is provided at the front of the protective box body 1, and a back panel 4 is provided at the rear of the protective box body 1. A wiring mechanism is provided on the upper portion of the back panel 4, and an equipment mounting plate 5 is provided on the lower front side of the back panel 4. An electrical isolation mechanism is provided between the back panel 4 and the equipment mounting plate 5.

[0027] like Figure 3As shown, in this embodiment, two connecting plates 10 are fixed to the front side of the back plate 4, and the two connecting plates 10 are arranged vertically and parallel to each other. The electrical isolation mechanism includes a connecting rod 6 and an insulator 7. The connecting rod 6 is arranged horizontally, and one end of the connecting rod 6 is connected to the back plate 4 through the connecting rod 6, and the other end is connected to the equipment mounting plate 5. The insulator 7 is arranged on the connecting rod 6. Specifically, the insulator 7 is a rod-shaped porcelain column, and a plurality of rod-shaped porcelain columns are arranged at equal intervals on the connecting rod 6. By installing the connecting rod 6 and the insulator 7 between the back plate 4 and the equipment mounting plate 5, electrical isolation is achieved, the protective box body 1 is prevented from being electrified, and safety is improved.

[0028] In this embodiment, multiple equipment mounting racks 8 are located on the side of the equipment mounting plate 5 facing away from the back panel 4. These racks 8 are evenly spaced vertically, and tempered glass partitions 9 are placed between adjacent racks 8.

[0033] The working principle of the protection device for power transmission and distribution control equipment in this embodiment is:

[0034] The top of the protective box body 1 is surrounded by a rainproof rock 2, providing rain protection. Connecting rods 6 and insulators 7 are installed between the back panel 4 and the equipment mounting plate 5 to achieve electrical isolation, preventing the protective box body 1 from becoming electrically charged. Tempered glass partitions 9 serve as insulating spacers, separating the rows of control equipment and providing electrical isolation for greater safety.
