Description

Technical Field

[0001] This invention belongs to the field of high-voltage busbar insulation treatment technology, and in particular relates to a green and environmentally friendly high-voltage busbar insulation treatment process. Background Technology

[0002] High-voltage busbars require insulation treatment, which involves installing insulating sleeves on them. Currently, the insulation sleeves are typically installed using heat fusion. The sleeve is placed on the high-voltage busbar and then shrunk through heat fusion to completely cover the busbar for insulation. However, heat fusion shrinkage is polluting and not environmentally friendly, and it also poses safety hazards for workers during the operation. Summary of the Invention

[0003] This invention discloses a green and environmentally friendly high-voltage busbar insulation treatment process, which mainly solves the problems of current high-voltage busbar insulation treatment being neither environmentally friendly nor safe.

[0004] To address the above problems, this invention provides a green and environmentally friendly high-voltage busbar insulation treatment process, comprising the following steps: S1: The support tube is inserted into the insulating sleeve using a sleeve-making machine, and the insulating sleeve is stretched and shaped; the support tube is a tubular structure formed by spirally connecting support bars; S2: Tear open the head of the support strip at one end of the support tube, then pass the torn head of the support strip through the support tube and extend it to the other end of the support tube. The end of the support strip head that is torn open is called the torn end. S3: Insert the high-voltage busbar that needs to be insulated into the support tube from the torn end; S4: Pull the head of the support bar to tear it open, so that the support tube is taken out from the insulation sleeve in the structure of the support bar. Without the support of the support tube, the insulation sleeve shrinks to cover the high voltage busbar.

[0005] Preferably, both sides of the support strip are provided with protrusions and grooves, and the grooves on both sides are in opposite directions.

[0006] Preferably, the forming process of the support tube is as follows: the support strip is spirally wound and connected by a spiral winding machine. During the connection process, the protrusion is hot-melted by a hot melt bar. The hot-melted protrusion is inserted into the groove under spiral winding, and finally spiral winding forms the support tube.

[0007] Preferably, the sleeve-making machine includes a machine base, a connecting plate disposed on the surface of the machine base, and a shaping tube. The end of the shaping tube near the connecting plate is detachably provided with a conical head. The machine base is provided with a driving device for driving the shaping tube to move. The connecting plate is provided with a through hole through which the shaping tube can pass. A cloth cover is provided on the connecting plate at the position corresponding to the through hole. Both ends of the cloth cover are open ends, and the end of the cloth cover away from the connecting plate is connected to a pull rod through a connecting strap.

[0008] The steps for inserting the support tube into the insulating sleeve are as follows: S11: Pass the cloth cover through the insulating sleeve; S12: Start the drive device to drive the shaping tube to move and pass into the cloth cover, open and shape the insulating sleeve, and the end of the cloth cover away from the connecting plate is called the open end; S13: Turn the open end of the cloth cover outward to the surface of the insulating sleeve, and remove the cone head; S14: Then fold the open end of the fabric cover inward into the shaping tube, pass the pull rod through the support tube, and then insert the support tube into the shaping tube; S15: Finally, start the drive device again to pull the shaping tube out of the insulating sleeve. At the same time, the cloth cover is pulled out directly, and then the insulating sleeve covers the support tube.

[0009] Preferably, a layer of lubricating oil is brushed onto the cloth cover before it passes through the insulating sleeve.

[0010] Preferably, the insulating sleeve is made of silicone rubber.

[0011] Preferably, the thickness of the insulating sleeve is 2mm to 6mm.

[0012] The technical solution provided by this invention has at least the following technical effects: In this invention, when insulating a high-voltage busbar, the insulating sleeve is opened by a support tube, the high-voltage busbar is inserted into the support tube, and finally the support tube is pulled out by a support bar, so that the insulating sleeve covers the high-voltage busbar, thus achieving insulation treatment of the high-voltage busbar. Compared with the current method of heat-melting shrinkage, this method is more environmentally friendly and safer. Attached Figure Description

[0019] Reference Figure 1 This embodiment discloses a green and environmentally friendly high-voltage busbar insulation treatment process, including the following steps: S1: The support tube 7 is inserted into the insulating sleeve 8 (the insulating sleeve 8 is made of silicone rubber) through a sleeve-fitting machine, and the insulating sleeve 8 is stretched and shaped; the thickness of the insulating sleeve 8 is 2mm to 6mm, and the support tube 7 is a tubular structure formed by spiral connection of support strips 9; Refer to Figure 4 and Figure 5 The support strip 9 has protrusions 91 and grooves 92 on both sides, with the grooves 92 on both sides facing opposite directions. During the spiral winding process of the support strip 9, the connection is achieved through the assembly of the grooves 92 and the protrusions 91, ultimately forming the support tube 7. The specific forming process of the support tube 7 is as follows: The support strip 9 is spirally wound using a spiral winding machine (the specific working principle of the equipment is well known to those skilled in the art and will not be described in detail in this embodiment). During the connection process, the protrusions 91 are heat-melted using a hot melt rod. The heat-melted protrusions 91 are then inserted into the grooves 92 during spiral winding, ultimately forming the support tube 7. The heat-melting temperature is set according to the actual situation, mainly to achieve the connection between the grooves 92 and the protrusions 91. During the subsequent disassembly of the support tube 7, it can be easily disassembled into the support strip 9 with a little force.

[0020] After processing and forming, the support bar 9 needs to be inserted into the insulating sleeve 8 with a smaller outer diameter by a sleeve-sleeving machine. The structure of the sleeve-sleeving machine can be referred to as 3. The sleeve-sleeving machine includes a machine base 1, a connecting plate 2 and a shaping tube 3 set on the surface of the machine base 1. The end of the shaping tube 3 near the connecting plate 2 is detachably equipped with a cone head 4. The function of the cone head 4 is to facilitate the insertion of the shaping tube 3 into the cloth cover 5. The machine base 1 is equipped with a driving device for driving the shaping tube 3 to move. The driving device mainly uses, but is not limited to, a cylinder. The connecting plate 2 is provided with a through hole for the shaping tube 3 to pass through. The connecting plate 2 is provided with a cloth cover 5 at the position corresponding to the through hole. Both ends of the cloth cover 5 are open ends, and the end of the cloth cover 5 away from the connecting plate 2 is connected to a pull rod 6 by a connecting strap.

[0021] Reference Figure 2 , Figure 6 The specific process is as follows: S11: Pass the cloth cover 5 through the insulating sleeve 8; before the cloth cover 5 passes through the insulating sleeve 8, brush a layer of lubricating oil on the cloth cover 5. The lubricating oil mainly reduces the friction between the cloth cover 5 and the insulating sleeve 8, making it easier for the cloth cover 5 to be removed from the insulating sleeve 8 later.

[0022] S12: Start the drive device to move the shaping tube 3 and insert it into the cloth cover 5, thus opening and shaping the insulating sleeve 8. The end of the cloth cover 5 away from the connecting plate 2 is called the open end; the open end is connected to the pull rod 6 through two connecting straps. S13: Flip the open end of the cloth cover 5 outward to the surface of the insulating sleeve 8, and remove the cone head 4; S14: Then fold the open end of the cloth cover 5 inward into the shaping tube 3, pass the pull rod 6 through the support tube 7, and then insert the support tube 7 into the shaping tube 3; S15: Finally, start the drive device again to pull the shaping tube 3 out of the insulating sleeve 8. At the same time as pulling it out, the cloth cover 5 is pulled out directly, and then the insulating sleeve 8 covers the support tube 7.

[0023] S2: Tear open the head of the support strip 9 at one end of the support tube 7, then pass the torn head of the support strip 9 through the support tube 7 and extend it to the other end of the support tube 7. The end where the head of the support strip 9 of the support tube 7 is torn open becomes the torn end. S3: Insert the high-voltage busbar that needs to be insulated into the support tube 7 from the torn end; S4: Pull the head of the support strip 9 to tear it open, so that the support tube 7 is taken out from the insulating sleeve 8 with the structure of the support strip 9. Without the support of the support tube 7, the insulating sleeve 8 shrinks to cover the high voltage busbar; thus achieving insulation treatment of the high voltage busbar. Compared with the current method of heat-melting shrinkage, it is more environmentally friendly and safer.

[0024] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
