Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for live-line work, and in particular to a tool for quickly shielding the T-junction of overhead conductors. Background Technology

[0002] Live-line working refers to the method of performing maintenance and testing on high-voltage electrical equipment without interrupting power. Electrical equipment requires frequent testing, inspection, and maintenance during long-term operation. Live-line working is an effective measure to avoid power outages during maintenance and ensure normal power supply. Live-line working can be divided into several aspects, including live-line testing, live-line inspection, and live-line maintenance. The objects of live-line working include electrical equipment in power plants and substations, overhead transmission lines, distribution lines, and distribution equipment. The main tasks of live-line working include: replacing line tower insulators under energized conditions, cleaning and replacing insulators, flushing insulators with water, crimping and repairing conductors and overhead ground wires, inspecting faulty insulators, testing and replacing disconnecting switches and surge arresters, and testing transformer temperature rise and dielectric loss values. Based on the relationship between the human body and the live conductor, live-line working can be divided into three categories: equipotential work, ground potential work, and intermediate potential work.

[0003] Currently, when workers inspect the nodes at both ends of the power line, the wire joints on the power line are easily touched by the workers. Therefore, a shielding device is needed to shield them. Now, a quick shielding tool for overhead conductor T-joints is designed to quickly shield the overhead conductor T-joints and prevent workers from accidentally touching the joints during maintenance.

[0007] In one embodiment, the length of the back panel of the insulating plastic box is greater than the length of the front panel, and the top of the insulating plastic box is hollow.

[0008] In one embodiment, the L-shaped protective plate and the insulating plastic box are integrally formed, and the length of the L-shaped protective plate and the insulating plastic box after being connected together is the same as the length of the back panel of the insulating plastic box.

[0009] In one embodiment, the reinforcing plates are provided with grooves on the plates on the side that are close to each other, and the bottom of the reinforcing plates extends downward to the outside of the bottom of the shielding box.

[0010] In one embodiment, a handle is provided at the center of the L-shaped insert plate on the side of the plate away from the shielding box.

[0011] In one embodiment, the length of the side plate of the L-shaped insert plate near the inner cavity of the shielding box is adapted to the length of the front of the insulating plastic box, and the thickness of the side plate of the L-shaped insert plate near the inner cavity of the shielding box matches the width of the groove body.

[0012] In one embodiment, the width of the L-shaped insert plate near the inner cavity of the shielding box is the same as the distance between the back plate of the shielding box and the L-shaped protective plate, and the L-shaped insert plate is made of insulating plastic.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] This utility model discloses a quick shielding device for T-junctions of overhead conductors. Through the positional relationship and design of the insulating plastic box, the L-shaped protective plate, and the semi-circular clamping plate, the staff can directly cover the shielding box on the junction. At the same time, through the design of the shape and size of the sealing plate, and the sliding groove designed in the reinforcing plate, the sealing plate can cover the box, thereby preventing the shielding box from falling off the junction and ensuring that it can always cover the junction.

[0022] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0023] like Figure 1-5 As shown, a quick shielding device for T-junctions of overhead conductors includes: a shielding box 1 and a sealing plate 2; the shielding box 1 includes an insulating plastic box 11, with semi-circular clamping plates 12 on both sides of the top of the insulating plastic box 11, an L-shaped protective plate 13 on the front of the insulating plastic box 11, and reinforcing plates 14 on the bottom of the insulating plastic box 11 and the bottom of the L-shaped protective plate 13; the sealing plate 2 includes an L-shaped insert 21, which is inserted into the opening on the right side of the insulating plastic box 11. It should be noted that the bottoms of the insulating plastic box 11 and the L-shaped protective plate 13 are both open designs, and the radius of the semi-circular clamping plate 12 is adapted to the radius of the wire, allowing the shielding box 1 to be secured to the T-junction of the overhead conductor.

[0024] like Figure 1-5 As shown, in one embodiment, the length of the back panel of the insulating plastic box 11 is greater than the length of the front panel, and the top of the insulating plastic box 11 is hollow. The L-shaped protective plate 13 is integrally formed with the insulating plastic box 11, and the length of the L-shaped protective plate 13 after it is connected to the insulating plastic box 11 is the same as the length of the back panel of the insulating plastic box 11. The reinforcing plates 14 have grooves 15 on their adjacent sides, and the bottom of the reinforcing plates 14 extends downwards to the outer side of the bottom of the shielding box 1. It should be noted that the distance between the back panel of the insulating plastic box 11 and the L-shaped protective plate 13 is greater than the width of the T-junction's top view, and a plastic handle is provided in the center of the top of the shielding box 1 for easy lifting by the operator.

[0025] like Figure 1-5As shown in one embodiment, a handle 22 is provided in the center of the L-shaped insert plate 21 on the side away from the shielding box 1. It should be noted that this design facilitates the insertion of the sealing plate 2 into the shielding box 1 by the operator.

[0026] like Figure 1-5 As shown in one embodiment, the length of the side of the L-shaped insert 21 closest to the inner cavity of the shielding box 1 is adapted to the length of the front of the insulating plastic box 11, and the thickness of the side of the L-shaped insert 21 closest to the inner cavity of the shielding box 1 matches the width of the groove 15. The width of the side of the L-shaped insert 21 closest to the inner cavity of the shielding box 1 is the same as the distance between the back plate of the shielding box 1 and the L-shaped protective plate 13. The L-shaped insert 21 is made of insulating plastic. It should be noted that after the shielding box 1 covers the contact point, because the contact point is generally designed to withstand an inclined angle, the bottom of the contact point will be located on one side of the bottom of the shielding box 1. At this time, inserting the sealing plate 2 from the other side will allow the sealing plate 2 and the shielding box 1 to snap together, thereby fixing it on the contact point and shielding the entire contact point.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
