Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof oil-immersed current transformers, and in particular to an explosion-proof oil-immersed current transformer. Background Technology

[0002] The sealed parts of oil-immersed current transformers are prone to damage or defects when exposed to the outdoor environment for extended periods. This can also allow external gases or liquids to enter the interior of the oil-immersed current transformer, potentially causing an explosion. The poor overall protection of oil-immersed current transformers directly affects their explosion-proof performance.

[0003] The existing patent CN222600725U describes an explosion-proof oil-immersed current transformer, which includes an insulating porcelain bushing, a flange A installed at the bottom of the insulating porcelain bushing, an expansion joint installed at the top of the insulating porcelain bushing, an oil tank installed at the bottom of flange A, and a flange B installed at the top of the oil tank. Both flanges B and flange A have annular seals installed on their outer walls. The structure is reasonable. By incorporating annular seals and a protective coating mechanism, flange B on the oil tank is assembled to flange A below the insulating porcelain bushing on the oil-immersed current transformer. The annular seals, along with sealing rings A and B, seal flanges A and B, thus minimizing leakage at the installation point between the oil tank and the insulating porcelain bushing after installation. This ensures a good seal and effectively reduces the possibility of explosion of the oil-immersed current transformer.

[0004] The existing equipment is fixed to the device via a base, and the holes for fixing on the base are pre-drilled. In actual use, there will be a situation where the holes on the device do not match the holes on the base, requiring additional drilling, which reduces work efficiency. Utility Model Content

This solution solves the problem that in actual use, the hole positions of the equipment do not match the hole positions on the base, requiring additional drilling, which reduces work efficiency.

[0020] In this specific embodiment, the main body 101 is installed on the oil tank 100. The main body 101 is the current transformer described in the prior art patent CN222600725U, "An Explosion-proof Oil-immersed Current Transformer". The main body 101 is installed above the oil tank 100. By providing an annular sealing element and a protective coating mechanism, the flange B on the oil tank is assembled to the flange A below the insulating porcelain sleeve on the oil-immersed current transformer. Then, the annular sealing element, together with sealing rings A and B, seals flanges A and B, minimizing leakage at the installation point between the oil tank and the insulating porcelain sleeve after installation. The sealing is guaranteed, effectively reducing the possibility of explosion of the oil-immersed current transformer. This solution allows for free adjustment of the position of the fixed base, thereby avoiding mismatch between the equipment holes and the holes on the base, and improving installation efficiency.

[0021] The fixing ring 102 is slidably connected to the oil tank 100 and is located on the side of the oil tank 100 away from the main body 101.

The sliding plate 104 is slidably connected to the support plate 103 and is located on the side of the support plate 103 away from the fixing ring 102. The fixing frame 105 is connected to the sliding plate 102. 04. A fixed connection is established, located on the side of the sliding plate 104 away from the support plate 103. The fixing member is installed on the sliding plate 104 and fixes the sliding plate 104. The fixing ring 102 is slidably installed on the oil tank 100. A reinforcing member is installed on the fixing ring 102 and tightens the fixing ring 102 through the reinforcing member, so that the fixing ring 102 is stably connected to the oil tank 100, thereby supporting the oil tank 100. The support plate 103 is installed on the fixing ring 102 by welding. The support plate 103 supports the oil tank 100 and the body 101 via the fixing ring 102. The sliding plate 104 is slidably mounted on the support plate 103. The support plate 103 has a sliding groove that mates with the sliding plate 104, allowing the sliding plate 104 to slide on the support plate 103. The fixing frame 105 is welded to the side of the sliding plate 104 away from the support plate 103, allowing the fixing frame 105 to move on the support plate 103 via the sliding plate 104. 05 has multiple holes on the side away from the sliding plate 104. The fixing member is installed on the sliding plate 104 and the sliding plate 104 is fixed by the fixing member, so that the sliding plate 104 is held in a specified position. The fixing frame 105 can stably support the sliding plate 104 and the support plate 103, so that the support plate 103 can stably support the fixing ring 102. This allows the position of the fixing base to be freely adjusted, thereby avoiding the situation where the hole position of the equipment does not match the hole position on the base, and improving the installation efficiency.

[0022] Secondly, the reinforcing strip 106 is fixedly connected to the support plate 103 and is located on the side of the support plate 103 away from the sliding plate 104. The reinforcing strip 106 is installed on the top of the support plate 103 by bolts. The reinforcing strip 106 reinforces the support plate 103 and prevents the support plate 103 from deforming, thereby making the sliding plate 104 and the fixing frame 105 more stably support the support plate 103.

[0023] Meanwhile, the clamping plate 107 is fixedly connected to the fixing ring 102 and is located on the side of the fixing ring 102 closer to the oil tank 100; the fastening bolt 108 is rotatably connected to the clamping plate 107 and is located on the side of the clamping plate 107 away from the oil tank 100. The clamping plate 107 is loosely attached to the opening of the fixing ring 102 by welding. The fastening bolt 108 is installed on the clamping plate 107 and passes through both clamping plates 107. The clamping plate 107 is tightened by the fastening bolt 108, thereby enabling the fixing ring 102 to be stably fixed on the oil tank 100.

[0024] In addition, the abutting tooth 109 is fixedly connected to the support plate 103 and is located on the side of the support plate 103 away from the sliding plate 104; the fixing block 110 is connected to the sliding plate 104 through the driving element, the driving element drives the fixing block 110 to move, the fixing block 110 engages with the abutting tooth, there are multiple abutting teeth 109, the abutting teeth 109 are evenly installed on the support plate 103, the fixing block 110 has a groove that cooperates with the abutting tooth 109, the fixing block 110 is installed on the sliding plate 104 through the driving element, the driving element drives the fixing block 110 to move, thereby making the fixing block 110 engage with the abutting tooth 109, thereby fixing the sliding plate 104 in a designated position.

[0025] Finally, the threaded rod 111 is rotatably connected to the sliding plate 104 and is located on the side of the sliding plate 104 near the support plate 103, and is connected to the fixing block 110; the rotating block 112 is fixedly connected to the threaded rod 111 and is located at the end of the threaded rod 111 away from the fixing block 110. The threaded rod 111 is rotatably mounted on the sliding plate 104, and the sliding plate 104 has a threaded hole that mates with the threaded rod 111, thereby allowing the threaded rod 111 to move within the sliding plate 104. The fixing block 110 is rotatably mounted on the threaded rod 111. By rotating the threaded rod 111 within the sliding plate 104, the fixing block 110 is moved, causing the fixing block 110 to engage with the abutment tooth 109, thereby fixing the sliding plate 104. The rotating block 112 is bolted to the threaded rod 111, and by rotating the threaded rod 111 through the rotating block 112, the workload of the workers is reduced.

[0026] Using an explosion-proof oil-immersed current transformer according to this embodiment, when the mounting holes do not match during installation, the threaded rod 111 is first moved by the rotating block 112, causing the fixing block 110 to move away from the abutting tooth 109, allowing the sliding plate 104 to move on the support plate 103. At this time, the sliding plate 104 is moved so that the holes on the fixing bracket 105 are aligned with the holes on the equipment. Then, the threaded rod 111 is rotated by the rotating block 112, causing the threaded rod 111 to drive the fixing block 110 to abut against the abutting tooth 109, thereby fixing the sliding block. This allows for free adjustment of the position of the fixing base, thus avoiding mismatch between the holes on the equipment and the holes on the base, and improving installation efficiency.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
