Problems solved by technology

[0002] It is stipulated in the electrical safety work regulations that "power outage or insulation shielding measures should be taken for adjacent live lines and equipment that may be touched during work", but when working on outdoor poles, since there is no special insulation shielding device and the existing insulation The shielding measures are inconvenient to install, and a safe distance is often used visually. Pay attention to maintaining a safe distance during work, especially at present, there are more and more cases where 10kV and 380V are installed on the same pole. Generally, only low-voltage power is stopped during low-voltage operations, and high-voltage live. There are major safety hazards during operation

Abstract

The invention relates to a folding insulation shielding device used on a pole. The device comprises an insulation hoop, an insulation shield and a telescopic insulation ruler, the insulation shield isinstalled on the insulation hoop, the insulation shield can be folded and unfolded to form an annular plane, the insulation shield and the insulation hoop are connected in a sliding mode, and the telescopic insulation ruler is fixedly installed on the insulation hoop and is perpendicular to the insulation shield. According to the invention, the technical blank is filled up, and the device is foldable, convenient to carry, selectable in various types, suitable for various voltage classes, capable of safely measuring distance and capable of reliably shielding electrified equipment. Meanwhile, the operation is extremely simple, and the workload is not increased while the safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of power distribution inspection and relates to an insulation shielding technology, in particular to a folding insulation shielding device on a pole. Background technique [0002] It is stipulated in the electrical safety work regulations that "power failure or insulation shielding measures should be taken for adjacent live lines and equipment that may be touched during work", but when working on outdoor poles, there is no special insulation shielding device, and the existing insulation The shielding measures are inconvenient to install, and a safe distance is often used by visual inspection. Pay attention to maintaining a safe distance during work, especially at present, there are more and more cases where 10kV and 380V are mounted on the same pole. Generally, only low-voltage power is stopped during low-voltage operations, and high-voltage live. There are great potential safety hazards during operation. Contents o...
