Embodiment 1

[0026] refer to Figure 1-3 , the present invention provides a lightning protection insulator with a built-in ejection mechanism, including an insulator body 2, a wire clamping fitting 1, an insulating base 3 and a grounding fitting 4, the top of the insulator body 2 is provided with a wire clamping fitting 1, and the insulator body 2 The bottom end is connected to the grounding hardware 4 through the insulating base 3. 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. After the breakdown, 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 airbag 61, an ejection plate 62, an ejection portion 63, and an ejection rod 64; They are respectively connected to two opposite side walls of the cavity, and the whole formed by the ejection plate 62 and the ejection portion 63 is para...

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 with built-in ejection mechanism, 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 a 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 anair bag, an ejection plate, an ejection cylinder and an ejection rod. The invention is used for making obvious marks on the insulator, which is convenient for patrol personnel to quickly find the insulator struck by lightning, and ensures the normal operation of the line.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a lightning protection insulator with a built-in ejection mechanism. 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 f...
