Color ceramic insulator having phase electricity recognition function

Abstract

The invention discloses a color ceramic insulator having a phase electricity recognition function. The color ceramic insulator comprises a yellow phase-A insulator, a green phase-B insulator, a red phase-C insulator and a black phase-O insulator which are formed by applying glaze materials with different colors on insulator blanks; the glaze materials consist of 85-90 weight percent of basic glaze material, 10-15 weight percent of coloring agent and a high temperature resistant opacifier in an amount which is 1 to 5 percent based on the total weight of the basic glaze material and the coloring agent; and the insulator is prepared by the steps of uniformly stirring and mixing the basic glaze material, the coloring agent and the high-temperature resistance opacifier to prepare the glaze materials with different colors, applying the glaze materials with different colors on the insulator blanks and firing at high temperature. In the invention, phase electricity is directly distinguished by using the glaze materials with different colors to form the yellow insulator, the green insulator, the red insulator and the black insulator; when the insulator is used on an overhead line or electrical equipment in a power station, the phase electricity can be rapidly, conveniently, accurately and permanently distinguished, so incorrect connection of phase electricity is avoided, the working intensity for wiring is reduced, the operation cost is reduced, the working efficiency is improved, and safety accidents can be prevented.

Description

technical field [0001] The invention relates to insulators used for overhead lines in the electric power industry and power station appliances, in particular to a colored porcelain insulator capable of quickly, accurately and permanently identifying phase electricity. Background technique [0002] At present, porcelain insulators for power transmission and transformation overhead lines and various porcelain insulators for power station appliances in China, including transformers, capacitors, transformers, pillars, wall bushings, switches and other porcelain insulators, are all made of a single color, usually brown, White, there are sky blue and gray in foreign countries. No matter what color is used for production, insulators of the same color are used for erecting lines with different phases and for the same electrical appliance with different phases, which will result in different phases. The electric line and the phase electricity on the same electrical appliance with di...

[0002] At present, porcelain insulators for power transmission and transformation overhead lines and various porcelain insulators for power station appliances in China, including transformers, capacitors, transformers, pillars, wall bushings, switches and other porcelain insulators, are all made of a single color, usually brown, White, there are sky blue and gray in foreign countries. No matter what color is used for production, insulators of the same color are used for erecting lines with different phases and for the same electrical appliance with different phases, which will result in different phases. The electric line and the phase electricity on the same electrical appliance with different phase electricity cannot be distinguished. How to distinguish the phase electricity on the overhead line and power station electrical appliances with the same color insulator, no matter at home or abroad, the following methods are currently used to distinguish the phase electricity : One is to make metal signs on the iron tower of the overhead line (on the cross arm of the pole); the o
