Description

Technical Field

[0001] This utility model relates to the field of transformer transportation, specifically a transformer transportation fixing structure. Background Technology

[0002] During long-distance transportation, transformers experience increased vibration, necessitating robust anti-vibration measures for their components to ensure mechanical strength and prevent potential quality issues. For example, patent CN217485214U discloses a fixing structure for a large transformer transporter. This fixing mechanism, located beneath the tank cover, includes components such as support blocks, stepped blocks, laminated wood boards, a tank fixing plate, and adjusting shims. This structure addresses the issue of securing the core side columns of a bell-shaped tank, improving transformer stability during transport. Another example is patent CN203312025U, which discloses a fixing structure for transporting transformer leads. This structure primarily prevents loosening and damage to the lead-out device caused by sudden acceleration or emergency braking during transport of large transformers. Furthermore, patent CN202784230U discloses a transformer anti-collision transport structure. This structure removes and fixes the shielding ring to the transport cover, better securing it to prevent impacts during transport and effectively preventing shaking of the lead-out device, thus protecting it from damage.

[0003] For dry-type transformers, the conductive rod is an important component. It is usually located outside the high-voltage coil and spans the entire transformer. During normal operation, the conductive rod is only fixed to the coil with bolts. However, during the transportation of the transformer, the conductive rod is easily deformed due to its large span. Some transformer products in the existing technology use plastic film to wrap and fix the conductive rod, but the film itself is easy to loosen, and its fixing effect on the conductive rod is not ideal. Utility Model Content

[0004] The purpose of this utility model is to provide a transformer transportation fixing structure, which uses a rigid insulating tube to connect the inner conductive rod and the outer conductive rod and provide support, thereby preventing the inner conductive rod and the outer conductive rod from deforming during transportation.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A transformer transport and fixing structure includes multiple transformer bodies, with any two adjacent transformer bodies connected by an inner conductive rod, and the two outermost transformer bodies connected by an outer conductive rod. A rigid insulating tube is provided between the inner and outer conductive rods, and both ends of the rigid insulating tube are connected to binding straps by elastic elements. The binding strap at one end of the rigid insulating tube is fixed to the inner conductive rod, and the binding strap at the other end is fixed to the outer conductive rod.

[0007] The device body includes a low-voltage coil, an insulating cylinder, and a high-voltage coil arranged sequentially from the inside to the outside. The low-voltage coil is fitted onto the corresponding core column of the iron core, and the high-voltage coil is provided with a connecting terminal. The two ends of the inner conductive rod and the two ends of the outer conductive rod are respectively fixed to the corresponding connecting terminal by bolts.

[0008] The inner conductive rod between two adjacent device bodies is connected to the outer conductive rod through at least one rigid insulating tube.

[0009] The binding strap includes a long strap and a short strap fixed to an elastic element, and the free end of the long strap is fixed to a buckle at the free end of the short strap.

[0010] The elastic element is a spring.

[0011] The advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model provides rigid insulating tubes for the inner and outer conductive rods, and the rigid insulating tubes can provide sufficient support to prevent deformation of the inner and outer conductive rods during transportation.

[0013] 2. The rigid insulating tube of this utility model is fixed at both ends to the inner conductive rod and the outer conductive rod respectively by binding straps. The binding straps and the rigid insulating tube are connected by elastic elements, which not only facilitates installation, but also allows for adaptive expansion and contraction according to the spacing between the inner and outer conductive rods, ensuring that the rigid insulating tube can be smoothly connected and bound.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, this utility model includes multiple bodies, with any two adjacent bodies connected by an inner conductive rod 5, and the two outermost bodies connected by an outer conductive rod 6. A rigid insulating tube 7 is provided between the inner conductive rod 5 and the outer conductive rod 6, and as shown... Figure 3 As shown, the two ends of the rigid insulating tube 7 are respectively connected to the binding straps 9 by elastic elements 8. The binding strap 9 at one end of the rigid insulating tube 7 is fixed to the inner conductive rod 5, and the binding strap 9 at the other end is fixed to the outer conductive rod 6.

[0020] This invention utilizes a rigid insulating tube 7 to provide support for the inner conductive rod 5 and the outer conductive rod 6, thereby preventing deformation of the inner conductive rod 5 and the outer conductive rod 6 during transformer transportation. In this embodiment, the rigid insulating tube 7 can be made of rigid plastic or other rigid insulating materials, and the elastic element 8 can be a spring capable of elastic extension and contraction. In addition to adapting to the spacing between the inner conductive rod 5 and the outer conductive rod 6, the spring can also provide flexible floating support for the inner conductive rod 5 and the outer conductive rod 6, thereby preventing direct contact between the rigid end of the rigid insulating tube 7 and the conductive rod, which could damage the outer sheath of the conductive rod.

[0021] like Figures 1-2 As shown, in this embodiment, the device body includes a low-voltage coil 12, an insulating cylinder 3, and a high-voltage coil 4 arranged sequentially from the inside to the outside. The low-voltage coil 12 is fitted onto the corresponding core column of the iron core 1. The high-voltage coil 4 is provided with a connecting terminal 10. The two ends of the inner conductive rod 5 and the two ends of the outer conductive rod 6 are respectively fixed to the corresponding connecting terminal 10 by bolts.

[0022] like Figures 1-2 As shown in this embodiment, pads 2 are provided at both the upper and lower ends of the device body, and the pads 2 at the upper end of the device body and the corresponding pads 2 at the lower end of the device body are connected by clamping bolts 11 to ensure that the device body is compacted.

[0023] The binding strap 9 is a technology known in the art. In this embodiment, the binding strap 9 includes a long strap 901 and a short strap 902 fixed on the elastic element 8, and the free end of the long strap 901 is fixed to the buckle 903 at the free end of the short strap 902 after passing over the conductive rod.

[0024] The working principle of this utility model is as follows:

[0025] This utility model involves assembling the transformer before transportation, specifically including the following steps:

[0026] Step 1: The low-voltage coil 12, the insulating cylinder 3, and the high-voltage coil 4 are sequentially mounted onto the corresponding core column of the iron core 1 to form the transformer body. Then, pads 2 are set at the upper and lower ends of the transformer body, and the pads 2 at the upper end of the transformer body and the corresponding pads 2 at the lower end of the transformer body are connected by clamping bolts 11 to ensure that the transformer body is compacted. Then, upper clamps and lower clamps are respectively set on the side of the upper and lower pads 2 away from the transformer body to clamp and fix the upper and lower ends of the iron core 1. The above process is a well-known technology in the field.

[0027] Step 2: Connect any two adjacent transformer bodies through the inner conductive rod 5, and connect the two outermost transformer bodies through the outer conductive rod 6. Each transformer body has a high-voltage coil 4 with a connection terminal 10. The two ends of the inner conductive rod 5 and the two ends of the outer conductive rod 6 are respectively fixed to the corresponding connection terminal 10 with bolts.

[0028] Step 3: First, select a rigid insulating tube 7 of appropriate length according to the spacing between the inner conductive rod 5 and the outer conductive rod 6. Then, select an appropriate number of rigid insulating tubes 7 according to the actual needs of the inner conductive rod 5 and the outer conductive rod 6 to ensure that the conductive rods are adequately supported and avoid deformation. At this time, the overall length of the rigid insulating tube 7 can be slightly off, and can be adjusted later by the elastic element 8.

[0029] like Figure 2 As shown, the inner conductive rod 5 between two adjacent device bodies is connected to the outer conductive rod 6 through at least one rigid insulating tube 7.

[0030] Step 4: Place the rigid insulating tube 7 between the inner conductive rod 5 and the outer conductive rod 6, and fix one end of the rigid insulating tube 7 with the binding strap 9 to the inner conductive rod 5, and the other end of the binding strap 9 to the outer conductive rod 6. If multiple rigid insulating tubes 7 are used, arrange the rigid insulating tubes 7 along the length of the conductive rod. In addition, during fixing, the elastic element 8 can adapt to the spacing between the inner conductive rod 5 and the outer conductive rod 6. After the binding is completed, send the entire transformer to the transport device and fix it.
