Embodiment Construction

[0047] figure 1 Among them, the umbrella disc string 3 is coated on the cylindrical outer surface of the mandrel 2, and the umbrella disc string 3 includes a cylindrical tube sleeved outside the mandrel 2, an umbrella disc arranged on the outer wall of the cylindrical tube, and the mandrel 2 is light. One end is inserted into the 4 holes of the pin-type fittings, and the crimping machine is used for crimping and fixing. The threaded end is screwed into the small hole 1 of the porcelain head 1. When screwing in, the adhesive 5 is filled in the gap between the two, and the umbrella disc strings 3. The interfaces between the ceramic head 1 and the pin fitting 4 are all sealed with silicon rubber, and the central axes of the porcelain head 1, mandrel 2, pin fitting 4, and screw 7 are located on the same straight line. The mandrel 2 is made of epoxy glass fiber, and the umbrella disc string 3 is made of silicone rubber or resin; the outer surfaces of the pin fittings 4 and the scre...

Abstract

The invention provides a porcelain head type pin composite insulator and a porcelain head bonding process. The porcelain head bonding process comprises the following steps: preparation of an adhesive:mixing epoxy resin after heat preservation and a curing agent according to a mass ratio of 1: 0.8-1.2, and defoaming under negative pressure to obtain the adhesive; treatment of bonded parts: dippingabsolute ethyl alcohol into a clean rag for cleaning one end of the core rod with the external thread and the interior of the small hole I of the porcelain head, smearing a silane coupling agent after the ethyl alcohol is completely volatilized, and airing at room temperature for later use; bonding of the porcelain head: quantitatively injecting the prepared adhesive into the small hole I of theporcelain head, then uniformly smearing the adhesive into a threaded groove in the threaded end of the core rod, then screwing the upper end part, combined with the porcelain head, of the core rod into the small hole I, and then manually cleaning the adhesive overflown from the combined part of the porcelain head and an umbrella tray string; and heating curing: placing the bonded porcelain head composite insulator into an oven at the temperature of 130 DEG C to 170 DEG C to be subjected to heat preservation curing, so that the cost of the pin type composite insulator is reduced, and the electrical performance is improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and relates to a porcelain-head pin-type composite insulator and a porcelain-head bonding process for the porcelain-head pin-type composite insulator. Background technique [0002] With the rapid development of the economy, people's demand for power resources is also increasing year by year. At the same time, with the development of the economy and the increase of electricity load, the problem of excessive short-circuit current of various regional power grids under the existing voltage level has become increasingly prominent, endangering the safe and stable operation of the power grid. Therefore, the electrical safety and reliability of transmission and distribution lines are becoming more and more important. [0003] In the power transmission and distribution lines, pin insulators used in large quantities are very important parts in the power transmission process, ...
