Problems solved by technology

[0002] Chinese patent (ZL 00 2 26500.1) discloses a rod-shaped post (porcelain core) composite insulator, as shown in Figure 1, it adds a sheath 2 to the outer layer of the Silicone rubber sheds 3 of different sizes are molded and formed. Due to the existence of the contact surface 4 between the silicone rubber sheds and the bonding interface 5 between the silicone rubber sheds 3 and the silicone rubber sheath, the bonding between the silicone rubber sheds 3 The flange 6 is designed, so that the contact surface 4 of the silicone rubber shed, the bonding interface 5 and the flange 6 are easy to accumulate dirt and difficult to clean, which brings hidden dangers to the operation
Its disadvantages are cumbersome process, high process requirements, large amount of manual operation, high labor intensity of workers, low production efficiency, and difficulty in large-scale production.
[0003] Secondly, in the operation of the existing process, because it is produced by a single shed bonding process, there are many sticky interfaces, and it is manually operated, and the operation difference in the production makes the operation hidden.

Embodiment 1

[0047] Embodiment 1 is a production process of continuously gluing the metal 9 at both ends. It is generally a process that can only be realized when the single-time production capacity of the equipment owned by the manufacturing company at least basically meets the height requirements of the unit product. The production of composite insulators The process is carried out according to the following steps: as shown in Figure 2, 1. Surface treatment of the glued parts at both ends of the porcelain mandrel 1 and the glued cavity of the metal 9 at the end, that is, after brushing with high-grade gasoline (such as 120#) Diluted asphalt paint to form a buffer layer; 2. The metal 9 at both ends of the porcelain mandrel 1 is glued with commercially available cement adhesive 8. Generally, the selected one is based on the mechanical strength requirements of the product and the operating voltage level. The grade and formula of cement are different. The grade of cement ranges from Portland ...

Embodiment 2

[0050] Example 2 is the equipment that some enterprises do not have a single production capacity. Therefore, it is possible to complete the production and manufacture of unit products only after two rounds of circulation processes. Its terminal metal 9 is glued first when the terminal metal 9 at one end is glued. Its procedure is:

[0051] 1) Prepare the surface treatment of the glue-mounted part of the porcelain mandrel 1 and the end metal 9 of one end;

[0052] 2) Glue the end metal 9 at one end first;

[0053] 3) Surface treatment of the plastic-mounted part of the end metal 9 of the glue-mounted porcelain mandrel 1;

[0054] 4) Preliminary vulcanization of the umbrella cover;

[0055] 5) Prepare the glue-mounted part of the porcelain mandrel 1 and the surface treatment of the glue-mounted cavity of the end metal 9 at the other end;

[0056] 6) Glue the metal 9 on the other end;

[0057] 7) Surface treatment of the ceramic mandrel 1 and the metal 9 at the two ends;

[00...

Embodiment 3

[0060] Embodiment 3 is that the production and manufacture of the unit product may be completed only after multiple times (or called "subsection vulcanization") process, and its operation is:

[0061] 1) Prepare the glued part of the porcelain mandrel 1 and the surface treatment of the metal 9 glued cavity at one end;

[0062] 2) Glue the end metal 9 at one end first;

[0063] 3) Surface treatment is carried out on the vulcanization molding part of the glued porcelain mandrel 1 and the end metal 9 of this end;

[0064] 4) Preliminary vulcanization of the umbrella cover;

[0065] 5) Treat the surface of the vulcanized part, that is, carry out mandrel 1 treatment step by step;

[0066] 6) Sequentially delay the initial molding of vulcanization;

[0067] 7) Prepare the glue-mounted part of the porcelain mandrel 1 and prepare the glue-mounted cavity surface treatment for the end metal 9 of the other end;

[0068] 8) Glue the end metal 9 on the other end;

[0069] 9) Perform s...

Abstract

The invention is concerned with the high-voltage transformer equipment, especially the compound insulator and the manufacture technics, the technics processes are: 1) disposes the surface of the preparing rubber-setting part; 2) sets rubber; 3) disposes the surface of the preparing vulcanization part; 4) vulcanize the formed umbrella cover; the processes can cycle timely. The compound insulator includes the main body (-) of the insulator, the porcelain mandrel (-) on the main body (-)of the insulator, and the silicon rubber umbrella-skirt (-), the characteristic is: the porcelain mandrel (-) on the main body (-)of the insulator covers the integrative silicon rubber umbrella-skirt (-) outside. The invention is simple technics, easy clean, high efficiency.

Description

technical field [0001] The invention relates to high-voltage power transmission and transformation equipment, in particular to a composite insulator and its manufacturing process. Background technique [0002] Chinese patent (ZL 00 2 26500.1) discloses a rod-shaped post (porcelain core) composite insulator, as shown in Figure 1, it adds a sheath 2 to the outer layer of the Silicone rubber sheds 3 of different sizes are molded and formed. Due to the existence of the contact surface 4 between the silicone rubber sheds and the bonding interface 5 between the silicone rubber sheds 3 and the silicone rubber sheath, the bonding between the silicone rubber sheds 3 The design of the flange 6 is adopted, so that the silicone rubber shed shed contact surface 4, the bonding interface 5 and the flange 6 are easy to accumulate dirt, difficult to clean, and bring hidden dangers to operation. Fig. 5 to Fig. 10 have provided the process flow of existing procedure and accompanying drawing: ...
