A spraying tool and spraying method for anti-pollution flashover paint of substation insulators

Abstract

The invention discloses a tool and method for spraying anti-pollution flashover paint on substation insulators. The system includes: an encircling mechanism, at least one spraying mechanism and a controller; The embracing mechanism is provided with at least one spraying mechanism, and the spraying mechanism can reciprocate in the circumferential direction along the embracing mechanism; the embracing mechanism is provided with a camera connected to the controller for assisting the positioning of the embracing mechanism around the insulator . The invention can realize spraying in the circumferential direction around the insulator, and ensures uniform spraying of the insulator by means of visual positioning.

Description

technical field [0001] The invention belongs to the technical field of substation live maintenance operations, and in particular relates to a spraying tool and a spraying method for an anti-pollution flashover coating on substation insulators. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Most of the high-voltage electrical equipment in the substation is installed outdoors, and the surface of the equipment will accumulate dirt when it is operated all the year round. Affected by the atmospheric environment, flashovers often occur under humid weather conditions, resulting in power outages. Regular spraying and RTV spraying of substation equipment is an effective means to maintain the original insulation level of equipment, prevent pollution flashover accidents, and ensure reliable operation of the power grid. RTV spraying of substation ...

AI Technical Summary

Problems solved by technology

[0005] The current automatic spraying mechanism is usually designed for circular spraying based on the specific shape of the insulator, but it is difficult to ensure whether the insulator is located in the center of the circle, and it can only be adjusted manually to ensure uniform spraying;

[0006] The position of the spraying mechanism relative to the insulator is fixed, which means that the spraying of the paint is relatively concentrated, and it is easy to appear uneven. However, the insulator includes multiple concave areas in the longitudinal direction, which is prone to dead angles that are difficult to spray, and the uniformity of spraying is difficult to guarantee.
