Description

Technical Field

[0001] This utility model relates to the field of reactor transportation, and in particular to a positioning device and a reactor. Background Technology

[0002] Reactors are widely used in circuits. Because of the electromagnetic induction effect in circuits, they have a certain degree of inductance, which can prevent changes in current.

[0003] In existing technologies, reactors are generally equipped with positioning devices, such as... Figure 1 As shown, the disc spring 01 typically contains a positioning pin 02, and the positioning cover 03 is generally designed in a top hat shape. This results in the positioning cover 03 being too tall, extending beyond the top of the reactor tank. However, reactors typically incur high transportation costs, with a single shipment costing over 2 million yuan. If the reactor is too tall, transportation may be hindered in adverse conditions such as mountainous areas or tunnels, potentially doubling the transportation cost. During reactor transportation, height restrictions can sometimes make transportation difficult, even by just a few centimeters. Therefore, it is necessary to reduce the height of the reactor to alleviate transportation costs to some extent. Utility Model Content

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] like Figure 2 As shown, this utility model discloses a positioning device, which includes: a limiting cylinder 20, a disc spring assembly 30 disposed within the limiting cylinder 20, a pad 40 disposed on the disc spring, a positioning cover 60 disposed on the pressure plate, and a positioning element 50 disposed between the fixing cover and the pressure plate. This utility model also discloses a reactor, which includes a positioning device, an upper yoke, a lower yoke, and two side yokes. A crossbeam 10 is disposed above the upper yoke, and the positioning device is disposed above the crossbeam 10.

[0029] The disc spring assembly 30 includes multiple disc springs. In a preferred embodiment of this utility model, the number of disc springs is four, and they are interlocked, that is, two disc springs are set upwards and two disc springs are set downwards, so as to balance the force and achieve the effect of shock absorption and noise reduction.

[0030] Furthermore, the positioning device of this utility model does not include a positioning pin. Eliminating the positioning pin in this utility model reduces the height of the positioning device and also prevents the positioning pin from generating excessive noise, thus achieving noise reduction.

[0031] Combination Figure 2 and Figure 3 As shown, specifically, the positioning cover 60 is annular, and has several threaded holes 601 and nuts arranged horizontally in the circumferential direction. The positioning cover 60 is detachably connected to the upper part of the positioning member 50 via nuts. The positioning cover 60 and the pad 40 are also detachably connected via nuts.

[0032] In this utility model, the positioning cover 60 is ring-shaped and has a lower height compared to the prior art. It can be completely installed inside the reactor's oil tank, and the transport height of the reactor depends only on the height of the reactor's oil tank, further reducing the difficulty of transportation.

[0033] Combination Figure 2 and Figure 4 As shown, in the positioning device of this utility model, the opening of the positioning member 50 faces upward, and the positioning cover 60 is disposed outside the positioning member 50. The inner diameter of the positioning cover 60 is larger than the outer diameter of the positioning member 50.

[0034] Specifically, the positioning component 50 includes a positioning bowl 501 and a base 502. The positioning bowl 501 is fixedly disposed above the base 502. The base 502 passes through the pad 40 and presses against the disc spring assembly 30. The positioning bowl 501 is disposed inside the positioning cover 60.

[0035] Combination Figure 2 and Figure 5 As shown, the positioning component 50 has several fixing through holes 503 arranged vertically inside, and the fixing through holes 503 penetrate the bottom of the positioning bowl 501 and the base 502. The positioning device also includes a screw 70, which is disposed in the fixing through holes 503. The fixing through holes 503 are evenly distributed vertically, and a vertical through hole 505 is provided between two adjacent fixing through holes 503. The inner diameter of the vertical through hole 505 is smaller than that of the fixing through hole 503.

[0036] The top of the positioning bowl 501 has several threaded holes 504 evenly distributed around its circumference. The threaded holes 504 are vertically arranged. The positioning bowl 501 and other required heightening parts in the reactor are detachably connected by bolts and threaded holes 504, which can realize the function of the reactor and facilitate transportation.

[0037] In this positioning device, a limiting cylinder 20 is fixed above the upper yoke. A disc spring assembly 30 is installed inside the limiting cylinder 20, and a pad 40 is mounted on the disc spring assembly 30. The pad 40 has a through hole at its center for the bottom of the positioning component 50 to pass through. The positioning cup 501 of the positioning component 50 is positioned above the pad 40, and a positioning cover 60 is positioned outside the positioning cup 501. The positioning cover 60 is fixedly connected to the pad 40 by a positioning nut, and the positioning cover 60 is bolted to the positioning cup 501. The positioning cover 60 can be easily disassembled to facilitate the transportation of the reactor.

[0038] In summary, the positioning device of this utility model eliminates the positioning pin structure and designs the positioning cover 60 as a ring. When applied to reactors, it can better reduce the transportation height of the reactor, reduce the transportation cost of ultra-high voltage reactors, and also reduce the operating noise of the reactor.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
