Description

Technical Field

[0001] This utility model relates to the technical field of live-line working tools, and in particular to a live-line working knife switch combination shielding device. Background Technology

[0002] Live-line working refers to the method of performing maintenance and testing on high-voltage electrical equipment without interrupting power supply. 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. The content of 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.

[0003] Currently, various shielding devices are required when performing live work on high-voltage power lines to prevent workers from being electrocuted during maintenance and inspection. Among these, the shielding of live switch blades, as the connection point of current, is particularly important. However, existing switch blade shields cover the entire switch blade and the surrounding cables. Therefore, when working on the cables around the switch blade, the existing shields are not convenient. It is necessary to replace them with insulating blankets for specific shielding. As a result, it is not convenient for workers to use these shields, and there are many limitations. Not only is the safety low, but the work efficiency is also not guaranteed. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1-8As shown, a live-line working knife switch combination shielding device includes: a knife switch shielding cover body 1, a semi-auxiliary shielding cover 2, and a full auxiliary shielding cover 3; an opening 12 is provided on the right side of the top of the knife switch shielding cover body 1; a first handle 11 is provided on the front and back of the knife switch shielding cover body 1 near the top center; first insertion holes 13 are provided on the left side of the bottom of the front and back of the knife switch shielding cover body 1 and the right side of the top; a first insertion post 14 is connected to the left side of the front of the knife switch shielding cover body 1 by an elastic rope; a second handle is provided on the center of the top of the semi-auxiliary shielding cover 2. 25. A second insertion hole 21 is provided at the bottom left side of the front of the semi-auxiliary shield 2. Hook plates 23 are provided at the bottom left side of the front and back of the semi-auxiliary shield 2. A baffle 24 is provided at the bottom of the left side plate of the semi-auxiliary shield 2. A top shield plate 31 is provided at the bottom right side of the full auxiliary shield 3. Auxiliary hook plates 32 are provided on the front and back of the top shield plate 31 near the full auxiliary shield 3. A single baffle 34 is provided on the right side of the back of the top shield plate 31. A third handle 33 is provided at the top center of the top shield plate 31 near the full auxiliary shield 3.

[0031] It should be noted that when the staff needs to shield the knife switch, first cover the knife switch shielding cover body 1 from top to bottom on the knife switch, and make the side with the observation port 15 close to the knife switch side. When maintenance is required around the knife switch, the semi-auxiliary shielding cover 2 can be inserted into the top right side of the knife switch shielding cover body 1, thereby isolating and sealing the knife switch in the semi-auxiliary shielding cover 2. The cables connected to the knife switch can be operated directly through the opening 12 on the knife switch shielding cover body 1.

[0032] After the maintenance near the switch is completed, the auxiliary shield 3 can be placed on top of the switch shield body 1. At this time, the top shielding plate 31 and the single-sided baffle 34 on the auxiliary shield 3 will completely cover the opening 12 on the switch shield body 1.

[0033] like Figure 1-2 As shown in one embodiment, the front of the knife switch shield body 1 is rectangular, and a square observation port 15 protruding outward is integrally formed in the center of its right side plate near the top. The inner cavity of the knife switch shield body 1 is a hollow structure, and its top plate has an open design. It should be noted that the observation port 15 extends away from the side where the top opening 12 is opened on the knife switch shield body 1. Therefore, this design allows the knife switch to extend into the observation port 15, and the open design facilitates heat dissipation at the knife switch.

[0034] like Figure 3-5As shown in one embodiment, the semi-auxiliary shield 2 has a square front shape and a hollow interior with an open bottom plate. The width of the semi-auxiliary shield 2's top view is greater than the width of the main body 1's top view. The semi-auxiliary shield 2 is inserted into the top right side of the main body 1, and the width of the side of the baffle 24 matches the width of the top central opening 12 of the main body 1. Hook plates 23 are located on the front and back of the baffle 24, and when the semi-auxiliary shield 2 is inserted into the main body 1, the hook plates 23 engage with the first handle 11. It should be noted that when the semi-auxiliary shield 2 is inserted into the top right side of the knife switch shield body 1, its first insertion hole 13 will overlap with the second insertion hole 21, and the second insertion post 22 will be inserted into the overlapping insertion hole, thereby restricting the semi-auxiliary shield 2 so that it will not fall off. At the same time, the hook plate 23 hooks to the right side of the first handle 11, thereby further restricting the position of the semi-auxiliary shield 2 on the knife switch shield body 1.

[0035] like Figure 6-8 As shown in one embodiment, the length of the front side of the auxiliary shield 3 connected to the top shield 31 is greater than the length of the front side of the main body 1 of the switch shield 1. When the auxiliary shield 3 is placed on top of the main body 1 of the switch shield 1, its auxiliary hook plate 32 will be fixed in the third handle 33. It should be noted that when the auxiliary shield 3 is placed on top of the main body 1 of the switch shield 1, the operator needs to insert the auxiliary hook plate 32 into the first handle 11, and at the same time, the single-sided baffle 34 should cover the opening 12 to block it.

[0036] like Figure 1-2 As shown, in one embodiment, the opening 12 is located on the top left side of the switch shield body 1, and the opening 12 extends towards the left side of the front panel of the switch shield body 1. It should be noted that this design facilitates the maintenance and repair of the cables in the switch shield body 1 by personnel.

[0037] like Figure 1-3 As shown, in one embodiment, a second insertion post 22 is fixedly connected to the bottom left side of the back of the semi-auxiliary shield 2 via an elastic cord. The diameter of the top view of the second insertion post 22 matches the diameter of the top view of the second insertion hole 21. It should be noted that this design allows the semi-auxiliary shield 2 to be fixed to the main body 1 of the knife switch shield 1.

[0038] 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.
