New lightning protection distribution box

Abstract

The invention discloses a new lightning protection distribution box comprising an outer box 1 and an inner box 2, wherein the outer box body is composed of five outer box plates, a clamp slot I is arranged on the inner plane of the outer box plates, the clamp slot I is matched with an insulating rubber pad, the upper end of the outer box plate on the bottom of the outer box is provided with a sliding slot I, a grounding drill rod communicating downward is disposed in the middle of the bottom of the outer box, the outer sides of the inner box body are respectively attached to the insulating rubber pad provided in the clamp slot I on the outer box plates, and the insulating rubber pad matched in the clamp slot III at the bottom of the box body is matched with the sliding slot I. In the new lightning protection distribution box, the outer box and the inner box are insulated and connected together by an insulating rubber pad, and a grounding drill rod is connected to the bottom of the outer box such that, when the distribution box is subjected to lightning strikes, the lightning directly contacts the outer box and is directly conducted to the bottom through the grounding drill rod, soas not to cause electric shock damage to the electrical components in the inner box.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution equipment, in particular to a novel lightning protection distribution box. Background technique [0002] In the process of power transmission, the distribution box is widely used in many places as an important equipment for power transfer. [0003] In the prior art, there are many types of distribution boxes with different structures. However, when encountering thunderstorms, especially in areas with high lightning explosions, the outdoor distribution boxes are likely to be damaged by lightning. , and many existing distribution boxes do not have the function of lightning protection. If a distribution box that can prevent being damaged by lightning can be designed, this kind of problem can be well solved. Therefore, the present invention proposes a A new type of lightning protection distribution box. Contents of the invention [0004] The purpose of the present inven...
