Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a display screen distribution box with a lightning protection function. Background Art

[0002] A distribution box is a low-voltage power distribution device that assembles power equipment such as switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Existing distribution boxes are not safe, and most distribution boxes are not equipped with lightning protection measures. Distribution boxes are extremely susceptible to lightning strikes in thunderstorms. Chinese patent publication number CN211182952U discloses a lightning protection distribution box, including a distribution box body consisting of a box body, a top cover and a base; a lightning rod is arranged on the top cover, and a grounding grid is arranged on the ground below the distribution box body. The lightning rod is grounded to the grounding grid through a lightning protection lead connected at the bottom. The utility model adopts a lightning protection mechanism composed of a lightning rod, a lightning conductor, and a grounding network, which is arranged on one side of the box body. When the thundercloud discharges close to the main body of the distribution box, the lightning rod distorts the electric field of the distribution box, and forms a space with a local electric field concentration at the top of the lightning rod, thereby affecting the development direction of the lightning leader discharge, guiding the lightning to discharge to the lightning rod, and then introducing the lightning current into the earth through the lightning conductor and the grounding network, thereby avoiding the distribution box from being struck by lightning, and realizing the lightning protection function of the main body of the distribution box. However, many birds build their nests next to the distribution box because the setting of the distribution box is stable, which often affects the heat dissipation of the distribution box. Over time, the heat inside the distribution box cannot be dissipated, resulting in thermal damage to the internal precision structure, reducing the service life of the distribution box. This patent does not have a bird-repelling function, and this patent only relies on the heat dissipation fan to dissipate heat, and the heat dissipation effect is poor. Utility Model Content
