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.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electric equipment, in particular to an anti-corrosion protection device for a rotating part of a connecting rod of an isolating switch. [0003] 【Background technique】 [0004] The isolating switch installed outdoors is exposed to the sun and rain during long-term operation, and it is very easy to cause corrosion and aging of metal parts. Therefore, it needs to be treated with anti-corrosion paint regularly during production and operation. However, the rotating part of the operating link of the isolating switch cannot be protected by painting because it is a movable component. Operation, even the failure of the connecting rod breakage occurs, shortening the operating life and maintenance cycle of the disconnector. [0005] 【Content of invention】 [0006] In order to solve the aforementioned problems, the present invention proposes an anti-corrosion protection device for the rotating part of the connectin...
