Example Embodiment

[0020] Example 1.

[0021] See figure 1 , An anti-corrosion protection device for the rotating part of the disconnect switch connecting rod, including a first mounting plate 1 and a second mounting plate 2 installed on the switch connecting rod, and a strip cover 3 for covering the rotating part; the strip cover 3 is fixed on On the first mounting plate 1 and the second mounting plate 2, the first mounting plate 1 and the second mounting plate 2 are provided with holes for accommodating the mounting parts; the strip cover 3 is in an inverted ∪ shape, and the side wall of the strip cover faces The strip cover is inclined 5° to 8°.

[0022] A hydrophobic layer is arranged on the outer surface near the bottom of the strip cover 3, the thickness of the hydrophobic layer is 0.3 mm to 0.47 mm, and the width of the hydrophobic layer is 0.5 cm to 1.1 cm. Within this range, the hydrophobic effect is good and the cost is low.

[0023] The inner wall of the strip cover 3 is provided with an ant

Abstract

The invention relates to an anti-corrosion protection device for the rotating part of a connecting rod of an isolating switch. ; The strip-shaped cover is fixed on the first mounting plate and the second mounting plate, and the first mounting plate and the second mounting plate are provided with holes for accommodating mounting parts; the strip-shaped cover is inverted ∪ Shape, the side wall of the strip-shaped cover is inclined 5° to 8° inwardly of the strip-shaped cover. The application can be reliably fixed on the rotating part of the isolating switch connecting rod, and will not fall off during operation; it can effectively protect the rotating part of the connecting rod from being exposed to the sun and rain, so as to delay its corrosion and aging speed and prolong its operating life.
