Description

Technical Field

[0001] This application relates to the technical field of transformer cores, and particularly to a transformer core that is convenient for hoisting. Background Art

[0002] The transformer core is an important component in a transformer, and its installation and disassembly processes often involve hoisting operations.

[0003] In traditional hoisting methods, it is usually necessary to use a hook to reach deep inside the transformer oil tank to suspend the core. However, due to the narrow space inside the oil tank, the hook is not only prone to bumping against the core and causing physical damage, but also inconvenient for the hook to be loaded and unloaded. Utility Model Content

[0004] The problem to be solved by this application is that the existing core requires a hook to reach deep inside the transformer oil tank for suspension hoisting operations, resulting in the hook not only being prone to bumping against the core in the narrow oil tank, but also being inconvenient for the hook to be loaded and unloaded.

[0005] To solve the above technical problems, this application provides a transformer core that is convenient for hoisting, including a core body for electromagnetic conversion operations, and hanging components arranged symmetrically on both sides of the upper end of the core body in a liftable and retractable manner for easy storage.

[0006] Since the hanging components are designed for the transformer core of this application, it is possible to not only achieve anti-collision hoisting operations of the core body through the raised hanging components, but also achieve unobstructed assembly operations of the transformer through the lowered hanging components, solving the problem that the existing core requires a hook to reach deep inside the transformer oil tank for suspension hoisting operations, resulting in the hook not only being prone to bumping against the core in the narrow oil tank, but also being inconvenient for the hook to be loaded and unloaded.

[0013] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment

[0014] The present application relates to a transformer iron core convenient for hoisting. As Figures 1-5 shown, the transformer iron core includes an iron core body 2 for electromagnetic conversion operation. In order to facilitate the hoisting operation of the iron core, therefore, hanging components 1 arranged in a liftable and retractable manner for easy storage are symmetrically arranged on both sides of the upper end of the iron core body 2. By pulling up the hanging components 1, the upper end is made to protrude above the transformer oil tank, which not only facilitates connection with the hook but also avoids the hook from bumping against the iron core body 2. By pushing down the hanging components 1 with the help of their own gravity, the upper end can be made to be lower than the edge of the transformer oil tank, thus facilitating the closing operation between the transformer tank cover and the oil tank.

[0015] The iron core body 2 includes a silicon steel sheet group 5, a clamping frame 4, a tie rod 3, and a bracket 6. The silicon steel sheet group 5 is arranged in the middle position inside the iron core body 2. Clamping frames 4 for clamping and fixing it are respectively arranged around the silicon steel sheet group 5, and tie rods 3 for connection and fixing are evenly and spaced between the clamping frames 4. In order to facilitate the stable placement of the iron core body 2 inside the transformer oil tank, therefore, a bracket 6 connected to the bottom of the clamping frame 4 at the lower end of the silicon steel sheet group 5 and serving as a support is added.

[0016] The hanging component 1 includes a lifting lug 7, a spring 8, a slide bar 10, and a support plate 9. The support plate 9 is horizontally arranged between the clamping frames 4 at the upper end of the silicon steel sheet group 5 and is fixed to them through the tie rod 3. A slide bar 10 perpendicular to it is arranged on the upper part of the support plate 9. The slide bar 10 can move freely up and down along the vertical direction. A lifting lug 7 connected to it by a nut is arranged at the upper end of the slide bar 10, and a plurality of nuts for restricting the lifting stroke of the slide bar 10 are arranged at the lower end of the slide bar 10. In order to prevent the slide bar 10 from sliding down along the vertical direction under its own gravity and colliding with the support plate 9, which not only easily generates metal debris but also may generate static electric arcs, therefore, a spring 8 sleeved on the slide bar 10 is arranged between the lifting lug 7 and the support plate 9, so that the spring 8 plays a buffering role when the slide bar 10 descends and slides.

[0017] When in use, when it is necessary to hoist the iron core body 2, first pull the sliding rod 10 upward at this moment so that the sliding rod 10 reaches the maximum upward movement stroke, and then connect the hook used for hoisting operation to the lifting lug 7, and then the suspended hoisting operation of the iron core body 2 can be carried out. After the stretched sliding rod 10 places the iron core body 2 inside the transformer oil tank, the horizontal height of the lifting lug 7 can be higher than the edge of the oil tank, so as to facilitate the disassembly operation of the hook. After the hook is disassembled, at this moment the hanging assembly 1 is in a free state, and then the sliding rod 10 will fall vertically along the support plate 9 under the action of its own gravity. Since there will be an acceleration when the sliding rod 10 falls, in order to avoid the rigid impact after the lifting lug 7 contacts the support plate 9, therefore, by means of the spring 8 sleeved on the upper part of the sliding rod 10, the compressed deformation of the spring 8 is used to play a role in buffering and absorbing energy for the falling of the sliding rod 10. When the sliding rod 10 falls to the lowest point and stops moving, at this moment the horizontal height of the lifting lug 7 is lower than the edge of the box body, so as to facilitate the connection operation between the transformer box cover and the box body.

[0018] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part depending on the context, the term "one or more" used in the text can be used to describe any feature, structure or property with a singular meaning, or can be used to describe a combination of features, structures or properties with a plural meaning. Similarly, at least in part depending on the context, terms such as "a" or "the" can also be understood to convey a singular usage or convey a plural usage.

[0019] It should be easily understood that the terms "on", "above" and "over" in this disclosure should be interpreted in the broadest manner so that "on" not only means "directly on something", but also includes the meaning of "on something" with intermediate features or layers therebetween, and "above" or "over" not only includes the meaning of "above" or "over something", but can also include the meaning of "above" or "over something" with no intermediate features or layers therebetween (i.e., directly on something).

[0020] In addition, in order to facilitate the description in the text, spatial relative terms can be used, such as "below", "beneath", "under", "above", "over", etc., to describe the relationship of one element or feature relative to other elements or features as shown in the figure. Spatial relative terms are intended to include different orientations of the device in use or operation other than the orientation shown in the drawings. The device can have other orientations (rotated 90 degrees or in other orientations), and the spatial relative descriptive words used in the text can be similarly interpreted.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
