RTV coating spraying technology for transformer substation post insulator

Abstract

The invention discloses a RTV coating spraying technology for a transformer substation post insulator. The technology specifically includes the following steps of A, preparing spraying solution; B, cleaning the surface of the insulator, and covering parts not to be sprayed; C, regulating the working temperature of a spraying device to be more than minus twenty degrees, and regulating the humidity of a working environment to be within the range of 20%-80%; D, using the spraying device for spraying; and E, examining the coating and eliminating defects. According to the RTV coating spraying technology, the thickness of the RTV coating on the surface of the insulator can be uniform, and thereby the service life of the insulator is prolonged.

Description

technical field [0001] The invention relates to a processing method for insulators in a power system, in particular to an insulator paint spraying process. Background technique [0002] RTV is a white room temperature curing silica gel. Its two most notable features are water increase and resistance to atmospheric and chemical pollution. It can be used as an anti-pollution flashover material on the insulating porcelain parts of electrical equipment in high-voltage substations in power systems. The electrical equipment is not affected by corona, ultraviolet rays, water corrosion and air dust pollution, and has a long service life and less maintenance workload. [0003] At present, spraying RTV paint on insulating porcelain bottles is mainly realized by manual spraying by workers. Although it is possible to flexibly spray different positions of insulating porcelain parts, there are the following disadvantages: 1) During the spraying process, a large amount of paint will not b...

AI Technical Summary

Problems solved by technology

Although it is possible to flexibly spray different positions of insulating porcelain parts, there are the following disadvantages: 1) During the spraying process, a large amount of paint will not be sprayed on the porcelain parts but will be sprayed into the air, which is not only inefficient and wasteful, but also Pollution to the surrounding environment; 2) The construction quality mainly depends on the experience of the construction personnel, and the uniformity of the coating thickness cannot be guaranteed, resulting in a decrease in hydrophobicity, aging and peeling problems, making it difficult to guarantee the quality of the coating; 3) During the construction process, the construction workers need to step on the surface of the porcelain bottle, and the safety rope is hung on the pillar of the porcelain bottle. Not only is it easy to damage the porcelain umbrella skirt, but it is also extremely unsafe for the construction workers; , wind speed, etc.) have a great influence on
