Variable energy current limiting lightning conductor convenient to fix

Abstract

The invention discloses a convenient and fixed energy-changing current-limiting type lightning rod, which comprises a lightning rod tip, a casing, a support rod, a first bushing and a second bushing, and the upper end of the second bushing is provided with a first bushing , one side of the first casing is provided with an upper connecting rod and a lower connecting rod, the upper connecting rod and the lower connecting rod are fixedly connected with the first casing through an L-shaped bracket, and the ends of the upper connecting rod and the lower connecting rod are respectively fixedly connected There are an upper collar and a lower collar, the upper end of the first casing is provided with a support rod, the upper end of the support rod is fixedly connected with a casing, the center of the casing is provided with a lightning guiding inner core, and the top of the casing is filled with an epoxy sealing layer, A through hole is opened in the middle of the epoxy sealing layer, and a lightning-termination needle tip is inserted in the through hole. The invention has a simple structure and a reasonable design, and can effectively prevent the electromagnetic field generated by the lower lead wire from affecting the surrounding electrical equipment. Easily blown over by wind and rain.

Description

technical field [0001] The invention relates to a lightning rod, in particular to a convenient and fixed energy-changing current-limiting type lightning rod. Background technique [0002] Lightning rod, also known as lightning rod, is a device used to protect buildings, tall trees, etc. , Lightning rods can effectively prevent these high buildings from being threatened by lightning. [0003] There are many types of modern lightning rods, but most modern lightning rods have defects. For example, modern lightning rods use lightning receptors to directly guide lightning into the ground through the lower lead wire. At this time, due to excessive voltage, it is easy to generate a very strong electromagnetic field. The surrounding electrical equipment has a certain damage effect. At the same time, the modern lightning rod is generally only fixed at the bottom, and the side is not auxiliary fixed. At this time, it is easy to be blown down in strong wind and rain, causing damage to...
