Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, to an energy-saving oil-immersed transformer. Background Art

[0002] An oil-immersed transformer uses oil cooling to reduce transformer temperature. Unlike dry-type transformers, oil-immersed transformers are housed in a welded steel tank filled with insulating oil. During operation, the insulating and heat-dissipating properties of the insulating oil improve transformer efficiency, thereby reducing energy consumption and achieving greater energy savings. Oil-immersed transformers are categorized by capacity as naturally cooled or forced-air cooled.

[0003] Currently, when oil-immersed transformers are installed outdoors, they are mainly connected by the angle steel at the bottom and the angle steel on the support body. At the same time, the oil-immersed transformer needs to be controlled by the lifting and lowering of the crane and manual dragging to achieve installation positioning. When the crane is lifting the oil-immersed transformer, it will not be able to quickly and stably position the position due to the swaying problem, which reduces the accuracy of installation positioning. At the same time, manually assisting the crane to tediously adjust the positioning position of the oil-immersed transformer will also increase the safety of workers working at heights.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an energy-saving oil-immersed transformer is provided in order to achieve a more practical purpose. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the technical problems of complicated hoisting and positioning of oil-immersed transformers and insufficient safety.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an energy-saving oil-immersed transformer, comprising an oil tank, an energy-saving transformer body and angle steel 1, the energy-saving transformer body being immersed in an oil tank containing transformer oil, the bottom of the oil tank being fixedly connected to a base, the bottom of the base being provided with angle steel 2 bolted to cooperate with angle steel 1, a pair of movable support assemblies being provided at the bottom of the base, a pair of wear-resistant plates being movably connected to the pair of movable support assemblies, a lifting assembly being movably connected to the pair of wear-resistant plates, and the lifting assembly being connected to the base.

[0007] In a preferred embodiment, the corners of the bottom of the base are fixedly connected with supporting legs, the number of the angle steels 2 is a pair, and the number of the angle steels 1 is also two, and each angle steel 2 is fixedly connected to an adjacent supporting leg.

[0008] In a preferred embodiment, reinforcement plates are fixedly connected to adjacent legs.

[0009] In a preferred embodiment, the number of the movable support assemblies is a pair, and each movable support assembly includes a support slide rail, which is connected to the bottom of the base through bolts, and a pair of support slide seats are slidably connected to the support slide rail.

[0010] In a preferred embodiment, adjacent support slides on a pair of support rails are connected with fixed hanging plates via bolts, and one end of the wear-resistant plate is hinged to the fixed hanging plate.

[0011] In a preferred embodiment, the wear-resistant plate is in active contact with an edge of a top portion of the angle steel, and a lubricating layer is provided on an outer surface of the wear-resistant plate.

[0012] In a preferred embodiment, the lifting assembly includes a connecting plate, the other end of the wear-resistant plate is hinged on the connecting plate, a screw is threadedly connected to the connecting plate, one end of the screw is rotatably connected to a support, and the support is connected to the bottom of the base by bolts.

[0013] Technical effects and advantages of this utility model:

[0014] 1. This energy-saving oil-immersed transformer is provided with a pair of V-shaped wear-resistant plates at the bottom of the oil tank. After a pair of angle steels 1 on the support body define the assembly position, the oil tank can first control the facing ends of the pair of wear-resistant plates to be located between the pair of angle steels 1 when it is lowered. In this way, the continuous lowering of the oil tank can make the edge of the angle steel 1 slide along the outer surface of the wear-resistant plates. In this way, the wear-resistant plates can play the effect of horizontally calibrating the placement position of the oil tank until the angle steel 2 is supported on the angle steel 1 to perform an effective fixing step. Therefore, the above positioning method is used to position the oil-immersed transformer, which can reduce the frequency of oil tank lifting and lowering adjustments, and at the same time reduce the frequency of auxiliary traction by high-altitude personnel, which is safer.

[0015] 2. This energy-saving oil-immersed transformer is equipped with a movable support assembly and a lifting assembly. The movable support assembly can provide sliding support for one end of the wear-resistant plate, and the lifting assembly can provide mobile traction for the other end of the wear-resistant plate. In this way, the cooperation of the lifting assembly and the movable support assembly can adjust the angle of a pair of wear-resistant plates to meet the positioning requirements of a pair of angle steels with different spacing.

DETAILED DESCRIPTION

[0023] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5 The utility model provides an energy-saving oil-immersed transformer, comprising an oil tank 1, an energy-saving transformer body and an angle steel 2, wherein the energy-saving transformer body is immersed in the oil tank 1 containing transformer oil.

[0025] Because the transformer oil in the oil tank 1 has excellent insulation properties and good heat dissipation capabilities, the energy-saving transformer body can be placed in the oil tank 1 to improve work efficiency. The improvement in work efficiency can reduce energy consumption. The reduction in energy consumption can make the energy-saving transformer body energy-saving. In this application, the angle steel 1 2 can be fixed on the support body, so that the angle steel 1 2 can provide high-altitude support for the oil tank 1, and the support body mostly adopts a telephone pole structure.

[0026] Specifically, the components of an oil-immersed transformer include the body, also referred to as the energy-saving transformer body in this application. The body primarily comprises the core, windings, insulation, leads, and other components. The oil-immersed transformer also includes oil-immersed transformer oil, an oil tank (1), a cooling device, a voltage regulator, protective devices, and lead bushings. The core is made of laminated silicon steel sheets, providing a magnetic circuit. The windings, comprised of wound wire and divided into high-voltage and low-voltage windings, are used to input and output electrical energy. Insulating oil fills the entire transformer, providing insulation and cooling the windings and core. When a high-voltage power source is connected to the transformer's high-voltage winding, the electrical energy generates a magnetic field in the winding. This field is conducted through the core to the low-voltage winding, inducing a corresponding voltage in the low-voltage winding. The insulating oil not only insulates the windings and core but also circulates, dissipating heat generated in the windings and core to maintain the transformer's normal operating temperature. Since the energy-saving transformer body is a mature, existing technology, it will not be further described here.

[0027] In this embodiment, the bottom of the oil tank 1 is fixedly connected to a base 3, and the bottom of the base 3 is provided with an angle steel 2 5 that is bolted to the angle steel 1 2.

[0028] The base 3 can provide support for the bottom of the fuel tank 1. When the fuel tank 1 is lifted and moved with the help of an existing crane until the angle steel 2 5 is overlapped on the angle steel 1 2, in this application, mounting holes are provided on the angle steel 1 2 and the angle steel 2 5, and bolts can be used to fix the angle steel 1 2 and the angle steel 2 5 with the corresponding mounting holes on the angle steel 1 2 and the angle steel 2 5.

[0029] In this embodiment: the corners at the bottom of the base 3 are fixedly connected with support legs 4, the number of angle steels 5 is a pair, and the number of angle steels 2 is also two, each angle steel 5 is fixedly connected to the adjacent support legs 4, and the adjacent support legs 4 are fixedly connected with reinforcement plates 10.

[0030] The legs 4 can provide support for the base 3 to land on the ground. The purpose of fixing the angle steel 5 on the legs 4 is to improve the supporting strength of adjacent legs 4. The reinforcement plate 10 can further provide the connection strength of adjacent legs 4.

[0031] In this embodiment: a pair of movable support assemblies 6 are provided at the bottom of the base 3, and the number of movable support assemblies 6 is a pair. Each movable support assembly 6 includes a support slide rail 61, and the support slide rail 61 is connected to the bottom of the base 3 by bolts. A pair of support slide seats 62 are slidably connected to the support slide rail 61.

[0032] The support slide 62 is arranged in an I-shaped structure, and a slide groove adapted to the support slide 62 is arranged in the support slide rail 61. The slide groove position of the support slide rail 61 can be embedded and connected to the base 3 using bolts, and the support slide 62 can provide sliding support for the connecting structure thereon.

[0033] In this embodiment: a pair of wear-resistant plates 8 are movably connected to a pair of movable support assemblies 6, and a fixed hanging plate 7 is connected to the adjacent support slides 62 on a pair of support rails 61 by bolts, and one end of the wear-resistant plate 8 is hinged to the fixed hanging plate 7.

[0034] The fixed hanger plate 7 can be integrated with the connection of a pair of movable support components 6, so that the pair of movable support components 6 can provide more stable sliding support for the fixed hanger plate 7. Because a pair of wear-resistant plates 8 are respectively arranged on the corresponding fixed hanger plates 7, the fixed hanger plate 7 can adjust the use position of the wear-resistant plates 8 so as to contact and cooperate with the angle steel 2.

[0035] In this embodiment, the wear-resistant plate 8 is in active contact with the edge of the top of the angle steel 2 , and a lubricating layer 81 is provided on the outer surface of the wear-resistant plate 8 .

[0036] When a pair of angle steels 2 are limited on the support body and the spacing between the pair of angle steels 2 is limited, the crane can now lift the oil tank 1 and move it toward the top of the angle steel 2. Because the pair of wear-resistant plates 8 are arranged in an inner eight shape, when the crane controls the oil tank 1 to descend, it can first control the facing end of the pair of wear-resistant plates 8 to be located between the pair of angle steels 2. In this way, the continuous descent of the oil tank 1 can make the edge of the angle steel 2 slide along the outer surface of the wear-resistant plate 8 until the pair of wear-resistant plates 8 are supported on the pair of angle steels 2. At this time, the angle steel 2 5 can be overlapped on the angle steel 2. The personnel at high altitude can connect the angle steel 2 and the angle steel 2 5 through bolt fasteners. Because the wear-resistant plate 8 can play the role of horizontally calibrating the placement of the oil tank, this can reduce the frequency of the oil tank 1 being raised and lowered by the crane, and at the same time reduce the frequency of auxiliary traction by personnel at high altitude, which is safer.

[0037] It is worth noting that, since the wear-resistant plate 8 is a bimetallic composite wear-resistant steel plate structure, this can improve the wear resistance of friction. In order to further reduce the wear of the wear-resistant plate 8, the outer surface of the wear-resistant plate 8 can be coated with a lubricating layer 81. The lubricating layer 81 can use lubricating oil as a lubricating material, which can reduce the wear of the wear-resistant plate 8 and the top edge of the angle steel 2. Furthermore, a curvature can be set at the top edge of the angle steel 2, which can provide smoothness in the contact between the wear-resistant plate 8 and the angle steel 2.

[0038] In this embodiment: the lifting assembly 9 includes a connecting plate 91, the other end of the wear-resistant plate 8 is hinged on the connecting plate 91, a screw 92 is threadedly connected to the connecting plate 91, one end of the screw 92 is rotatably connected to a support 93, and the support 93 is connected to the bottom of the base 3 by bolts.

[0039] A handwheel can be installed at the bottom end of the screw 92 to drive the screw 92 to rotate. In order to meet the positioning requirements of a pair of angle steels 2 with different gaps, the screw 92 is rotated by the handwheel, and the screw 92 threaded transmission connecting plate 91 can lift the wear-resistant plate 8. The fixed hanging plate 7 on the end side of the wear-resistant plate 8 can push the supporting slide 62 to slide in the supporting slide rail 61. In this way, the angle of the pair of wear-resistant plates 8 can be adjusted to adapt to the positioning and support of a pair of wear-resistant plates 8 and a pair of angle steels 2 with different spacings.

[0040] Specifically, when adjusting the angle of the wear-resistant plate 8, the spacing between a pair of wear-resistant plates 8 can be observed horizontally at the bottom of the angle steel 2 5 until the spacing matches the spacing between a pair of angle steels 1 2, so as to ensure that the angle steel 2 5 is effectively overlapped on the angle steel 1 2.

[0041] It is worth noting that since the supporting slide rail 61 and the base 3, the fixed hanger 7 and the supporting slide 62, and the support 93 and the base 3 are all connected by bolts, by releasing the bolt connection and adjusting the spacing of a pair of wear-resistant plates 8 to be smaller than the spacing of a pair of angle steels 2 through the lifting assembly 9, the movable supporting assembly 6, the lifting assembly 9 and the wear-resistant plate 8 can be taken out from the bottom of the base 3 for reuse.
