Description

Technical Field

[0001] The utility model relates to the field of insulating baffles, in particular to an insulating baffle of a transformer on a distribution line pole. Background Art

[0002] Insulating baffles are made of insulating materials and are used to isolate live parts, limit the range of activities of workers, and prevent people from approaching high-voltage live parts. They are generally insulating plates with high insulation performance. They can be in direct contact with live parts of 35kV and below, and serve as temporary barriers. Most insulating baffles are made of epoxy resin. Currently, most insulating baffles on the market are whole plates. When it is necessary to climb onto the distribution line pole for maintenance, if the insulating baffle affects the maintenance, it needs to be removed. However, the placement and removal of the entire baffle are very troublesome, and the length of the entire plate is fixed, which makes it difficult to meet different usage environments. Utility Model Content

[0003] The main purpose of the utility model is to provide an insulating baffle for a transformer on a distribution line pole, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an insulating baffle of a transformer on a distribution line pole, comprising a plurality of "I"-shaped insulating rods and a mounting frame, insulating connecting rods are movably installed inside the two sides of the insulating rods, adjacent insulating rods are connected and installed by a connecting rod, a penetrating circular groove is opened on the surface of the insulating rod in the middle position, a circular shaft is fixedly installed on the surface of the mounting frame, the circular shaft movably penetrates the inside of the circular groove, an anti-drop plate is fixedly installed on the end of the circular shaft, and the connecting rod is connected to the surface of the mounting frame through a fixing component.

[0005] The mounting frame is arranged in a "π" shape, and the distance between two supporting legs of the mounting frame is greater than the length of the insulating rod.

[0006] Screws are threadedly installed on the surface of the connecting rod at the two outermost ends. The screw threads penetrate through the surface of the connecting rod and are threadedly installed inside the mounting frame.

[0007] Fixed shafts are fixedly installed at the top and bottom ends of both sides of the insulating rod, and two grooves are provided at both ends of the connecting rod. The fixed shafts are movably installed inside the grooves.

[0008] An installation groove is provided inside the groove, and the installation groove penetrates the side area of ​​the connecting rod close to the groove. The depth of the installation groove is less than the depth of the groove, and the length of the fixed shaft is greater than the depth of the installation groove.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. In the utility model, screws, insulating rods and connecting rods are arranged, and the screws make each insulating rod and connecting rod be placed in a "cross" with the installation position of the mounting frame, so that it can play a blocking role. When the insulating baffle needs to be removed for maintenance, the screws are removed and the entire insulating baffle is rotated around the circular axis. At this time, there is no blocking effect of the mounting frame, so the insulating rod and the connecting rod can be rotated and folded with each other, which will not block the sight of the staff and is convenient for the staff to carry out maintenance.

[0011] 2. In the utility model, by setting connecting rods, insulating rods, fixed shafts, grooves and mounting grooves, the connecting rods are clamped inside the insulating rods until the sum of the widths of all the connecting rods and the insulating rods reaches the length of use. When the number of insulating rods and connecting rods is increased, the fixed shaft is first clamped into the inside of the mounting groove. Since the depth of the mounting groove is shallower, it is easier to clamp into the inside of the mounting groove. Then the connecting rod is moved so that the fixed shaft is clamped into the inside of the groove. This makes the installation of the connecting rods and the insulating rods more convenient and adaptable to different usage environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3As shown, an insulating baffle of a transformer on a distribution line pole comprises a plurality of “I”-shaped insulating rods 1 and a mounting frame 2, insulating connecting rods 3 are movably mounted inside both sides of the insulating rods 1, adjacent insulating rods 1 are connected and mounted via a connecting rod 3, a penetrating circular groove 4 is provided on the surface of the insulating rod 1 at the middle position, a circular shaft 5 is fixedly mounted on the surface of the mounting frame 2, both the mounting frame 2 and the circular shaft 5 are made of insulating material, the circular shaft 5 movably penetrates the inside of the circular groove 4, an anti-slip plate 6 is fixedly mounted on the end of the circular shaft 5, and the connecting rod 3 is connected to the surface of the mounting frame 2 via a fixing assembly.

[0018] When installing the insulating baffle, the connecting rod 3 is stuck inside the insulating rod 1 until the sum of the widths of all the connecting rods 3 and the insulating rod 1 reaches the length of use. At this time, it can be installed through the fixing assembly, so that each insulating rod 1 and the connecting rod 3 are placed in a "cross" with the installation position of the mounting frame 2. At this time, it can play a blocking role. When the insulating baffle needs to be removed for maintenance, the fixing assembly is removed and the entire insulating baffle is rotated around the circular axis 5. At this time, there is no blocking effect of the mounting frame 2, so the insulating rod 1 and the connecting rod 3 can be rotated and folded with each other, which will not block the staff's line of sight and facilitate the staff to carry out maintenance.

[0019] The mounting frame 2 is configured in a “π” shape, and the distance between the two supporting legs of the mounting frame 2 is greater than the length of the insulating rod 1 , which will not affect the folding of the insulating rod 1 and the connecting rod 3 .

[0020] The surface of the connecting rod 3 at the outermost two ends is threadedly installed with screws 7, which can easily penetrate the connecting rod 3. The screws 7 thread through the surface of the connecting rod 3 and are threadedly installed inside the mounting frame 2 to ensure the insulation performance of the back of the insulating baffle.

[0021] A fixed shaft 8 is fixedly installed at the top and bottom ends of both sides of the insulating rod 1, and two grooves 9 are provided at both ends of the connecting rod 3. The fixed shaft 8 is movably installed in the groove 9, and the insulating rod 1 inside can rotate around the fixed shaft 8, thereby realizing the folding function.

[0022] An installation groove 10 is opened inside the groove 9, and the installation groove 10 penetrates the side area of ​​the connecting rod 3 close to the groove 9. The depth of the installation groove 10 is less than the depth of the groove 9, and the length of the fixed shaft 8 is greater than the depth of the installation groove 10. When the number of insulating rods 1 and connecting rods 3 is increased, the fixed shaft 8 is first inserted into the inside of the installation groove 10. Since the depth of the installation groove 10 is shallower, it is easier to insert into the inside of the installation groove 10. Then move the connecting rod 3 so that the fixed shaft 8 is inserted into the inside of the groove 9, which makes the installation of the hungry connecting rod 3 and the insulating rod 1 more convenient.

[0023] It should be noted that the utility model is an insulating baffle of a transformer on a distribution line pole. When in use, when the number of insulating rods 1 and connecting rods 3 is increased, the fixed shaft 8 is first inserted into the inside of the installation groove 10. Since the depth of the installation groove 10 is shallower, it is easier to insert into the inside of the installation groove 10. Then the connecting rod 3 is moved so that the fixed shaft 8 is inserted into the inside of the groove 9 until the sum of the widths of all connecting rods 3 and the insulating rods 1 reaches the length of use. At this time, it can be fixed and installed by screws 7, so that each insulating rod 1 and connecting rod 3 is placed in a "cross" with the installation position of the mounting frame 2, which plays a blocking role. When the insulating baffle needs to be removed for maintenance, the screws 7 are removed, and the entire insulating baffle is rotated around the circular axis 5. The insulating baffle is suspended at the position of the circular axis 5. At this time, there is no blocking effect of the mounting frame 2, so the insulating rod 1 and the connecting rod 3 can be rotated and folded with each other, which will not block the staff's line of sight and facilitate the staff to carry out maintenance.
