specific Embodiment

[0032] Insulator base material: C795 high alumina porcelain. The limit function of the insulator makes the insulator bear a large shear stress during use, so C795 high-alumina porcelain material with high bending strength is selected.

[0033] Insulator surface treatment method: hydrophobic glaze layer. After the surface of the insulator is coated with a hydrophobic glaze layer, it can greatly slow down the accumulation of tar or particles on the surface of the insulator.

[0034] Insulator structure design: The structure of the insulator is mainly composed of the main body, the bosses at both ends and the limit key. The design principles and dimensions of each structure, such as figure 1 , figure 2 and image 3 shown.

Abstract

The invention relates to a high-voltage electrostatic insulating ceramic insulator with a limiting function. The ceramic insulator comprises an insulator main body, wherein the insulator main body isa long waist-shaped body; bosses, outer diameters of which re same as the width of the long waist-shaped body are arranged at two ends of the long waist-shaped body; the two bosses are respectively located on two sides of the long waist-shaped body in the thickness direction; and a through hole for the passing of ring rod of an electric field is formed between the two bosses. A limiting lamping key is arranged on one boss; and the limiting clamping key is embedded in a corresponding opening on an electric field polar plate to ensure that the electric field polar plate cannot deflect or displace and then the whole electric field structure is stabilized. The insulator is capable of generating and controlling the insulating distance. The bosses at two ends are capable of isolating the electric field polar plate from the insulator main body, so that negative and positive polar plates are prevented from directly creeping from the side surface of the insulator main body. By adoption of the design, the normal work of the insulator is not influenced even a large number of oil contaminations or particulate matters are stacked on the polar plates.

Description

technical field [0001] The invention relates to an insulator used for high-voltage electrostatic dust removal equipment, in particular to a porcelain insulator with a limiting function. Background technique [0002] Electrostatic adsorption technology is an efficient air dust removal technology. The high-voltage electrostatic dust removal equipment developed by using this technology is widely used in the tail gas treatment of thermal power stations and various kilns. [0003] The insulator is an important part of the high-voltage electrostatic precipitator, which is used for the insulation and isolation support between the cathode and anode plates of the electric field of the electrostatic precipitator. Insulators are divided into composite insulators, glass insulators, porcelain insulators, etc. according to their materials. Due to its wide applicable temperature range and good insulation performance, porcelain insulators have been widely used in industrial high-voltage el...
