Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a lightning rod for a power transmission and transformation iron tower. Background Art

[0002] The lightning rod for power transmission and transformation towers is composed of a lightning rod and a lightning receptor. It is usually used on steel pipe towers, angle steel towers, steel pipe poles, and structural supports. It is a device used to protect equipment from lightning strikes. The lightning rod for power transmission and transformation towers uses the metal tip of its lightning receptor to concentrate the electric field strength to form a strong electric field, thereby attracting lightning. In thunderstorm weather, the lightning rod for power transmission and transformation towers discharges through the tip to form an upward leader discharge, which distorts the electric field of the lightning cloud to form a lightning path, and transmits the lightning current to the existing power transmission and transformation iron on the ground through the grounding device. Tower lightning rod, the lightning rod of the traditional power transmission and transformation tower lightning rod can be detachably connected to the lightning rod, and can be replaced after the lightning rod is damaged by lightning. This type of lightning rod is generally connected to the top of the lightning rod by a thread, or a fastener is set at the top of the lightning rod to connect the fastener to the lightning rod to fix it. Since the straight-line heights of lightning rods for different power transmission and transformation towers are different, the wind force they withstand in the air is also different. This traditional power transmission and transformation tower lightning rod uses a single fastener to fix the poor stability and is easy to loosen after fixation. Utility Model Content
