Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The method for removing aging RTV paint on the surface of an insulator comprises the following steps: park the walking platform at a preset position, and rotate the rotary platform so that the dry ice cleaning device is located under the insulator. The scissor lifting device 20 drives the dry ice blasting device to rise, so that the dry ice blasting device and the insulator are at the same height. The insulating telescopic device protrudes outward to make the dry ice blasting device close to the insulator. After the dry ice cleaning device is aligned with the insulator, a mixture of dry ice and high-pressure gas is sprayed to clean the insulator.

[0022] Such as figure 1 The shown insulator surface aging RTV paint removal device includes an insulating telescopic device, a dry ice cleaning device and a walking mobile platform. The walking mobi...

Abstract

The invention discloses an insulator surface aged RTV paint eliminating method and device. The insulator surface aged RTV paint eliminating method comprises the following steps: a walking type platform is placed at a preset position, and a revolving platform rotates to make a dry ice cleaning device be located under an insulator; a shear fork lifting device drives the dry ice cleaning device to rise so that the dry ice cleaning device and the insulator can be at the same height; an insulating telescopic device extends out to make the dry ice cleaning device be close to the insulator; after being aligned with the insulator, the dry ice cleaning device ejects a mixture of dry ice and high pressure gas to clean the insulator. The insulator surface aged RTV paint eliminating method and device have a good effect in removing aged RTV paint and cannot affect the environment.

Description

technical field [0001] The invention relates to the technical field of electrical equipment cleaning, in particular to a method and device for removing aging RTV paint on the surface of insulators. Background technique [0002] The surface of porcelain / glass insulators of power transmission and transformation equipment is polluted by solid, liquid and gaseous conductive substances. When encountering the effects of fog, dew and drizzle, the conductivity of the dirty layer increases, the leakage current increases, and local Discharge and develop into arc flashover, which is called pollution flashover. Pollution flashover of equipment will seriously affect the safe operation of the power system, and when equipment pollution flashover occurs, the success rate of reclosing is very low, often causing large-scale power outages. The main measure to prevent pollution flashover in our country is to paint RTV (Room Temperature Vulcanized Silicone Rubber) on the substation equipment. ...
