Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth impregnation equipment, specifically to a glass fiber cloth impregnation device for dry air reactors. Background Technology

[0002] Dry-type reactors are open-type reactors that rely on airflow for heat dissipation and are primarily used in low-voltage power systems. They play a crucial role in limiting inrush current, reducing voltage notch effects, and minimizing voltage spikes. Compared to oil-immersed reactors, dry-type reactors are more suitable for low-voltage applications, while oil-immersed reactors are used in high-voltage environments. This product is widely used in key national engineering projects such as power plants, airports, chemical plants, and nuclear power plants, and has functions such as limiting short-circuit current, compensating for capacitor current, and filtering harmonics. Technically, it adopts VPI manufacturing process and computer design, and features high insulation strength, uniform temperature rise, and low loss.

[0003] The main function of fiberglass cloth in dry-type air-core reactors is for insulation, high-temperature resistance, and mechanical protection. Fiberglass cloth needs to be impregnated with resin to fill the pores between the fiberglass cloth, forming a dense insulation layer, which significantly improves the withstand voltage level and arc resistance, and is suitable for electrical equipment such as voltage reactors. Summary of the Invention

Detailed Implementation

[0018] like Figure 1-2As shown, a glass fiber cloth impregnation device for dry-type hollow reactors includes an unwinding roller 1 and a winding roller 2. A drive motor is installed on the winding roller 2. An impregnation device is arranged between the unwinding roller 1 and the winding roller 2. The impregnation device includes an impregnation tank 4 with an open top. A first rotating roller 5 and a second rotating roller 6 are arranged at intervals on the top of the impregnation tank 4. A third rotating roller 7 is installed inside the impregnation tank 4. The first rotating roller 5 is located on the side close to the winding roller 2. An extrusion device is arranged above the first rotating roller 5.

[0019] Specifically, as shown in the figure, the glass fiber cloth is wound on the unwinding roller 1. One end of the glass fiber cloth is pulled out and passes sequentially over the second rotating roller 6, under the third rotating roller 7, and over the first rotating roller 5, so that the glass fiber cloth enters the impregnation tank 4. The impregnation tank 4 contains adhesive, and the adhesive will coat the glass fiber cloth. The glass fiber cloth will come out from the top of the first rotating roller 5. The extrusion device can wipe off the excess adhesive on the outer surface of the glass fiber cloth. The take-up roller 2 is equipped with a drive motor, and the rotation of the take-up roller 2 drives the glass fiber cloth forward.

[0020] Both ends of the first rotating roller 5 and the second rotating roller 6 are connected to the bearing housing 23, which is installed on the top surface of the impregnation tank 4. Specifically, the first rotating roller 5 and the second rotating roller 6 rotate through the bearing housing 23.

[0021] The first rotating roller 5, the second rotating roller 6, and the third rotating roller 7 form a V-shaped structure. Specifically, the glass fiber cloth passes through the top of the second rotating roller 6 and the bottom of the first rotating roller 5 and the third rotating roller 7, so that the glass fiber cloth is completely immersed in the impregnation tank 4, thereby making the impregnation more thorough.

[0022] The extrusion device includes a fourth rotating roller 8, which is located above the first rotating roller 5. Both ends of the fourth rotating roller 8 are mounted on bearing seats 2 9. The bearing seats 2 9 are fixedly mounted on the top of the movable seat 10. The movable seat 10 is fixedly mounted on the top of the free end of the lifting cylinder 11. The fixed end of the lifting cylinder 11 is fixedly connected to the mounting plate 12. The mounting plate 12 is fixedly connected to both sides of the impregnation tank 4.

[0023] Specifically, the distance between the fourth rotating roller 8 and the first rotating roller 5 can be adjusted. The glass fiber cloth passes between the fourth rotating roller 8 and the first rotating roller 5 and comes into contact with the fourth rotating roller 8 and the first rotating roller 5, which will wipe off the excess adhesive on the outer surface of the glass fiber cloth. The adhesive-impregnated glass fiber cloth is then wound up on the take-up roller 2.

[0024] A blowing device is provided on the side of the first rotating roller 5; after the glass fiber cloth comes out of the impregnation tank 4, the blowing device dries it.

[0025] The blowing device includes at least two fans 18, which are located on the side of the first rotating roller 5. The air outlets of the fans 18 are connected to vertical air outlet pipes 19, and the vertical air outlet pipes 19 are connected to horizontal air outlet pipes 20. Multiple air outlet holes 21 are opened at the top of the horizontal air outlet pipe 20 of one fan 18, and multiple air outlet holes 21 are opened at the bottom of the horizontal air outlet pipe 20 of the other fan 18. One horizontal air outlet pipe 20 is located above the fiberglass cloth 22, and the other horizontal air outlet pipe 20 is located below the fiberglass cloth 22. Specifically, multiple fans can be set according to actual needs. In this embodiment, two fans 18 are set, with one horizontal air outlet pipe 20 located above the fiberglass cloth and the other located below the fiberglass cloth, allowing air to be blown onto both the top and bottom of the fiberglass cloth. A drying rack 13 is provided on the side of the air blower. The drying rack 13 has a U-shaped structure. The vertical part of the drying rack 13 can be fixed to the ground to prevent it from tipping over. A fifth rotating roller 14 and a sixth rotating roller 15 are provided between the two vertical parts of the drying rack 13. The sixth rotating roller 15 is located above and to the side of the fifth rotating roller 14. A horizontal support 16 is provided on the side of the two vertical parts of the drying rack 13 near the take-up roller 2. A seventh rotating roller 17 is provided between the two horizontal supports 16. Specifically, after the glass cloth comes out from the top surface of the first rotating roller 5, it goes to the bottom of the fifth rotating roller 15. The entire glass cloth is pulled horizontally. After coming out from the bottom of the fifth rotating roller 14, it comes down from the top of the sixth rotating roller 15 to the bottom of the seventh rotating roller 17. Finally, it is rolled up on the take-up roller 2. After the air blower, the natural drying time is increased.

[0026] A wooden board 24 is installed on the side floor of the glue dipping tank 4; specifically, if glue drips, it can drip directly onto the wooden board 24 to prevent the workshop floor from getting dirty.
