Surface dip-coating treatment process for power transformer post insulator

Abstract

The invention relates to a surface dip-coating treatment process for a power transformer post insulator. A bottom plate, a conveying device, dip-coating devices and an air drying device are included, the conveying device is arranged in the middle of the upper end face of the bottom plate, the dip-coating devices are installed on the upper end face of the conveying device in a bilateral symmetry mode, and the air drying device is fixedly arranged at the position, close to the rear end, of the upper end face of the conveying device. The surface dip-coating treatment process for the power transformer post insulator can solve the following possible problems in the process of spraying protective paint on the surface of the existing power transformer post insulator: a, the mode of manually spraying the protective paint on the surface of the power transformer post insulator by using a spray gun wastes time and labor and is relatively low in spraying efficiency, and the phenomenon of incomplete or non-uniform spraying may occur; and b, in the spraying process, the protective paint is exposed in the air in a mist state, and workers may inhale part of the paint when engaged in the spraying operation for a long time, so that certain harm is caused to the bodies of the workers.

Description

technical field [0001] The invention relates to the field of manufacturing power transformer post insulators, in particular to a surface dip coating treatment process for power transformer post insulators. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. The post insulator is a special insulation control installed on the power transformer, which can increase the creepage distance, usually made of silicone or ceramic. After the post insulator is manufactured, it is usually necessary to spray a layer of protective paint on its outer surface, so as to improve its corrosion resistance and prolong its service life. [0003] At present, the existing power transformer post insulators may encounter the following problems in the process of spraying protective paint on the surface: a. The surface of the po...

Problems solved by technology

[0005] The present invention can solve the following problems that may be encountered in the process of spraying the protective paint on the surface of the existing power transformer post insulators: a. Spray the protective paint on the surface of the power transformer post insulators manually using a spray gun, which is time-consuming and laborious. The spraying efficiency is low, and the spraying may be incomplete or uneven; b. During the spraying process, the protective paint is exposed to the air in the form of mist, and artificial spraying operations for a long time may inhale part of the paint, thus affecting artificial some body damage
