Method used

[0028] The limit card key 3 can be embedded in the corresponding opening on the electric field plate, so that the electric field plate cannot be deflected or displaced, and the entire electric field structure is stabilized.
[0029] With the bit card key 3 is a stable electric field mechanical structure. The original insulator has no limit card key, and the mechanical structure of the electric field is realized by fastening the front and rear bolt sets. After the purification device passes the factory inspection, the electric field will be slightly deformed during transportation to the customer's installation site. Although this deformation is very slight, it also affects the ...

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.

Example Embodiment

[0031] Specific embodiments of the present invention:
[0032] Insulator base material: C795 high alumina porcelain. The limit function of the insulator allows the insulator to withstand greater shear stress during use, so the C795 high-alumina ceramic material with high bending strength is selected.
[0033] Insulator surface treatment method: hydrophobic glaze layer. The hydrophobic glaze layer on the surface of the insulator 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 with image 3 Shown.
