Description

Technical Field

[0001] The present invention relates to the technical field of cable repair, and in particular to a low-voltage line insulation repair tool and a repair method thereof. Background Art

[0002] Low-voltage lines usually refer to power lines with AC voltages below 1000V, which are the terminal parts of the power system. During long-term use, ultraviolet radiation will break the molecular chains of the insulating materials (such as polyvinyl chloride, rubber, etc.) of low-voltage lines, resulting in a decrease in insulation performance. At the same time, in outdoor environments, after being exposed to the sun and rain, the insulation layer will become fragile and cracked, thus losing its insulation protection function. Lightning overvoltages caused by lightning weather or operating overvoltages caused by internal faults in the power system may cause the insulating material to withstand excessive voltages, exceeding its insulation tolerance, resulting in the breakdown of the insulation layer. When the insulation layer is broken down, the line will leak electricity, which may cause electrical fires in severe cases. At present, there are two ways to repair low-voltage lines. One is a relatively common simple repair method, which uses insulating tape (such as polyvinyl chloride insulating tape) to wrap around the damaged part. The other method uses the method of replacing the insulating sleeve to remove the insulation layer of the damaged part of the line, and then put on a suitable insulating sleeve. However, this method is relatively complicated to operate and requires certain techniques and tools. Generally, corresponding maintenance is carried out according to the degree of damage.

[0003] During the maintenance of low-voltage lines, when multiple points of low-voltage line conductors are damaged, electrical tape is used to repair the missing or damaged parts of the conductor insulation. Generally, it is repaired manually by wrapping electrical tape around the missing or damaged parts of the conductor insulation. Due to the different degrees of damage, the number of turns of tape required is different. For indoors, it is generally 3 to 5 turns, and for outdoors, it is generally 5 to 8 turns, or even more. For low-voltage line maintenance in outdoor environments, if there are many repair points and many turns of tape, the workload is large without auxiliary tools. Summary of the invention

[0056] S1. Place the wire to be repaired on the fixing component, and install the insulation repair tape roll on the tape releasing component.

[0057] Specifically, the wire to be repaired is placed in the guide groove portion 31 in the fixing component 3 , and the guide groove portion 31 can clamp the wire. Then, the insulating repair tape roll 8 is installed on the support column 55 on the release wheel 52 .

S4. When the insulation repair tape completes the winding process, the cutting component cuts off the insulation repair tape between the guide component and the insulation repair tape roll to complete the insulation repair of the low-voltage line.

[0061] Combination Figure 1 and Fig.10 , the repair principle of the low voltage line insulation repair tool of the present invention is explained:

[0062] The tape release component 5, the guide groove portion 31, the cutting component 6, and the hollow guide column 42 rotate synchronously. When repairing the wire in the low-voltage line, the wire is first placed in the guide groove portion 31, and then the insulation repair tape roll 8 is installed on the tape release component 5, and the insulation repair tape 100 on the insulation repair tape roll 8 is removed as shown in the figure. Fig.10The insulation repair tape 100 is wound around the hollow guide column 42 in the manner shown, and passes through the slit 310 on the guide groove portion 31, and then adhered to the wire in the guide groove portion 31. The sticky side of the insulation repair tape 100 contacts the hollow guide column 42, and the non-sticky side of the insulation repair tape 100 contacts the inner wall of the guide groove portion 31 in the guide groove portion 31, and the sticky side of the insulation repair tape 100 contacts the wire and adheres to the wire. Then, the tape release component 5, the guide groove portion 31, and the hollow guide column 42 are rotated clockwise, and the guide groove portion 31 can drive the wire to rotate. Since the tape release component 5, the guide groove portion 31, the cutting component 6, and the hollow guide column 42 are rotated synchronously, the insulation repair tape 100 can always be driven during the rotation of the wire, so that the insulation repair tape 100 follows the wire and is wound around the wire. At the same time, because the cutting component 6 rotates simultaneously with the guide groove portion 31 and the hollow guide column 42, the insulation repair tape 100 released from the insulation repair tape roll 8 during the rotation process 0 always passes over the hollow guide column 42, and the insulation repair tape 100 is always behind the cutting component 6. The cutting component 6 will not cut the insulation repair tape 100 during the rotation process. When the insulation repair tape 100 is wound a sufficient number of times, the rotation is stopped, and then the cutting component 6 is moved manually. The cutting component 6 pierces the insulation repair tape at the position of the multiple layers of insulation repair tape wound on the wire, and then the wire is taken out from the guide groove portion 31. Since the insulation repair tape has been pierced, the force on the wire when it is taken out will tear off the insulation repair tape at the connection end of the insulation repair tape on the wire and the insulation repair tape roll 8 again.

[0063] The invention provides a low-voltage line insulation repair tool, which can wrap a conductor with multiple turns of insulation repair tape, thereby reducing the work intensity of repairing the low-voltage line to a certain extent.

[0064] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
