Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a distribution box with a lightning protection function comprises a box body 1, a box door 10 is hinged to the front side face of the box body 1, a lightning protection device 2 is assembled at the top end of the box body 1, the lightning protection device 2 comprises a tip discharger 21 and a capacitor block 23, the capacitor block 23 is assembled on the inner top wall of the box body 1, a lightning rod 20 is assembled at the top of the capacitor block 23, drainage plates 22 are connected to the left end and the right end of the lightning rod 20, the tip discharger 21 is assembled at the top end of the drainage plates 22, a high-voltage-resistant capacitor 231 is connected in parallel inside the capacitor block 23, the bottom of the capacitor block 23 is connected with a grounding device 3, other circuit elements 4 are assembled inside the box body 1, when the distribution box is struck by lightning, the lightning rod 20 guides high-voltage electricity contained in lightning to the lightning protection device 2, one part of the high-voltage electricity is transferred into the tip discharger 21, and finally discharged through the grounding device 3, since the high withstand voltage capacitor 231 can withstand a higher voltage, the voltage does not leak, and other circuit elements 4 are burned out.

Specifically, the top of the box body 1 is covered with the insulating layer 11, and the drainage plate 22, the capacitor block 23 and the grounding device 3 are wrapped inside the insulating layer 11, so that the insulating layer 11 can prevent the lightning arrester 2 from contacting other circuit elements 4 to generate a discharge phenomenon due to a complex structure in the box body 1.

Specifically, since the electricity is easily conducted in a humid environment, the waterproof layer 12 covers the top of the insulating layer 11 to prevent water from entering the tank 1.

Specifically, a window 101 is formed on the surface of the door 10 to facilitate reading.

Specifically, the door 10 is fitted with a door lock 102 at the junction to protect the components inside the cabinet 1 from loss.

The working principle is as follows: when the block terminal suffers the thunderbolt, draw in the high-tension electricity that thunder pole 20 contains in with the thunderbolt to among the lightning arrester 2, high-tension electricity partly shifts to in the sharp discharger 21 through drainage plate 22, discharge through the principle of point discharge, another part gets into electric capacity piece 23, and finally discharge through earthing device 3, because high withstand voltage electric capacity 231 can bear higher voltage, consequently make voltage can not leak, burn out other circuit component 4, simultaneously because electric easy conduction under the humid environment, consequently waterproof layer 12 can prevent to intake in the box 1, prevent that the box 1 is inside to discharge.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
