Embodiment 1

[0026] refer to Figure 1-3 , the present invention provides a lightning protection insulator, comprising an insulator body 2, a clamping fitting 1, an insulating base 3 and a grounding fitting 4, the top of the insulator body 2 is provided with a clamping fitting 1, and the bottom end of the insulator body 2 is insulated The base 3 is connected to the grounding hardware 4. A cavity 5 is opened on one side of the insulating base 3, and an ejection mechanism 6 is provided in the cavity 5. The ejection mechanism 6 is used for marking. When the insulator is struck by lightning, It can be quickly marked on the insulator body 2, which is easy to find, specifically: refer to Figure 2-3 , the ejection mechanism 6 includes an air bag 61, an ejection plate 62, an ejection barrel 63 and an ejection rod 64; the ejection plate 62 is connected to two opposite side walls of the cavity, and the ejection plate 62 is connected to the bottom wall of the cavity Parallel, the airbag 61 is locat...

Embodiment 2

[0034] In order to further reduce the frictional force of the ejection rod sliding on the side wall, under the premise of including the above content, the end of the contact between the ejection rod and the side wall is set as a ball, so that the ejection rod and the side wall are also connected by a high pair.

Abstract

The invention discloses a lightning protection insulator, belonging to the technical field of insulators. The lightning protection insulator comprises an insulator body, a wire clamping fitting, an insulating base and a grounding fitting. The top end of the insulator body is provided with the wire clamping fitting, the bottom end of the insulator body is connected with the grounding fitting through the insulating base, a cavity is arranged on one side of the insulating base, and an ejection mechanism is arranged in the cavity. The ejection mechanism comprises an air bag, an ejection plate, anejection cylinder and an ejection rod. Obvious marks are made on the insulator, which is convenient for patrol personnel to quickly find the insulator struck by lightning, and ensures the normal operation of a line.

Description

technical field [0001] The present invention relates to the technical field of insulators, more specifically, to a lightning protection insulator. Background technique [0002] The insulator is a special insulation control, which can play the dual role of supporting the wire and preventing the grounding of the current in the overhead transmission line. Insulators are used in the connection between the pole tower and the wire, and the connection between the frame of the substation and the line. [0003] Insulators are exposed to the atmosphere all the year round, and are affected by factors such as lightning strikes, pollution, bird damage, ice and snow, high temperature, high cold, and altitude differences, which will lead to various accidents. A lightning strike disconnection accident on an insulated line may cause damage to the insulator. Since there is no obvious mark after the insulator is damaged, inspection personnel cannot intuitively find the fault point, which prol...
