Description

Technical Field

[0001] This utility model belongs to the field of oil-immersed magnetically controlled reactor assembly technology, specifically relating to a magnetically controlled reactor body assembly clamping fixture. Background Technology

[0002] With the rapid development of power electronic equipment and its expanding applications in industry, some power devices experience extremely drastic reactive power fluctuations during operation. This not only causes voltage fluctuations, flicker, and imbalances in the system but also injects a large amount of high-order harmonics, severely impacting the power quality of the power supply system. Static var compensators (SVCs) can quickly track load changes, compensate for reactive power fluctuations in the power grid, rapidly suppress voltage fluctuations and flicker, improve power factor, filter harmonics, stabilize the three-phase voltage at the system connection point, reduce three-phase voltage and current imbalance, and increase system stability. Magnetic-controlled reactors are one type of SVC, characterized by wide applicability, continuously stepless capacity adjustment, large adjustment range, low harmonics, no need for additional filtering devices, fast response speed, and convenient and quick adjustment. Currently, there are not many manufacturers capable of producing magnetic-controlled reactors, but with increasingly stringent power quality requirements, increasingly mature technology, and growing user acceptance of their applications, the market for magnetic-controlled reactors has a promising future. However, the structure of magnetically controlled reactors is relatively complex. In particular, the assembly efficiency of oil-immersed magnetically controlled reactors with double-layer three-phase five-column double-loop cross-parallel structure is usually low and the upper yoke is prone to deformation. This can lead to high product noise or even structural collapse.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Example: like Figure 1-3 As shown, this embodiment provides a magnetically controlled reactor body assembly clamping fixture, including an upper window high positioning fixture, a lower window high positioning fixture and a middle clamp 4, with the middle clamp 4 disposed opposite to the upper window high positioning fixture and the lower window high positioning fixture. The upper window high positioning fixture includes an upper coil pressing component 1, a first flange component 2, and a first connecting component 3; The lower window high positioning fixture includes a lower clamp 5, a second flange 6, and a second connecting piece 7; The first flange 2 and the second flange 6 are respectively installed in the middle clamp 4; The two ends of the first connector 3 are respectively connected to the upper coil pressing part 1 and the first flange part 2, and the upper window high positioning fixture and the middle clamping part 4 form a first clamping part. The two ends of the second connector 7 are respectively connected to the lower clamping part 5 and the second flange part 6, and the lower clamping part 5 and the middle clamping part 4 form a second clamping part.

[0018] The magnetically controlled reactor body assembly clamping fixture in this embodiment addresses the problem that existing reactor products have a three-phase, five-column, double-layer structure, and the assembly process is complex and time-consuming. This leads to the problem that the rebound force between the upper and lower coil layers of the reactor body is prone to rebound during long-term assembly. By using the upper window high positioning fixture, the lower window high positioning fixture, and the middle clamp 4 to form a first clamping part and a second clamping part, the upper and lower coil layers of the reactor body are clamped to prevent the rebound phenomenon between the coils. Then, the iron yoke laminations are installed, which can improve the efficiency of reactor body assembly, improve product assembly quality, and thus effectively reduce product noise and improve product structural safety and reliability.

[0019] The specific structure of the magnetically controlled reactor body assembly clamping fixture in this embodiment is as follows: First, there are two middle clamping parts 4, which are symmetrically arranged on both sides of the upper coil clamping part 1.

[0020] First fastening components are provided at both ends of the first connector 3, and second fastening components are provided at both ends of the second connector 7.

[0021] Specifically, the first connector 3 and the second connector 7 have the same structure, and the first fastening assembly and the second fastening assembly have the same structure. The first connector 3 is a double-ended screw, and both ends of the first connector 3 are provided with threaded portions; The first fastening assembly includes a nut 8, a flat washer 9, and a spring washer 10.

[0022] Specifically, the two ends of the first connecting piece 3 are slidably engaged with the upper coil pressing piece 1 and the first flange piece 2, respectively, and the two ends of the second connecting piece 7 are slidably engaged with the lower clamping piece 5 and the second flange piece 6, respectively.

[0023] The upper coil pressing member 1 in this embodiment includes a first pressing member 101, a second pressing member 102 and a third connecting member 103. The first pressing member 101 is disposed above the second pressing member 102, and the third connecting member 103 is connected to the first pressing member 101 and the second pressing member 102 respectively.

[0024] Specifically, the first pressure ring 101, the second pressure ring 102, and the third connecting part 103 are made of steel. The third connecting part 103 is connected to the first pressure ring 101 and the second pressure ring 102 by welding. The above structure can facilitate the manufacturing and assembly of the upper coil pressure part 1 and reduce the production cost of the entire tooling.

[0025] Specifically, a lifting lug 11 is provided at the top of the first pressure ring 101, and a pressure plate 12 is provided at the bottom of the second pressure ring 102.

[0026] Specifically, the first pressure ring 101 and the second pressure ring 102 are frame structures.

[0027] Based on the above structure, the specific usage method of this embodiment is as follows: First, install the lower body of the reactor body: assemble the lower body coil with the middle yoke. After assembly, connect the lower clamp 5 to the lower body of the magnetically controlled reactor body, and connect the middle clamp 4 to the middle yoke of the magnetically controlled reactor body. Connect the lower clamp 5 and the middle clamp 4 respectively through the second connector 7 to form the second clamping part to avoid rebound affecting the assembly space of the upper body. Next, assemble the upper body: After assembling the upper body coil, place the upper coil clamp 1 on the top of the reactor body, so that the upper coil clamp 1 acts on the coil insulation end ring. The upper coil clamp 1 and the middle clamp 4 are connected by the first connector 3 to form the first clamping part to prevent the coil from rebounding.

[0028] Because the first pressing ring 101 and the second pressing ring 102 in this embodiment are frame structures, it is easy to insert the yoke laminations and facilitate the insertion operation. Moreover, the structure of the pressure plate 12 ensures uniform pressure around the coil insulation end ring. This embodiment also includes a lifting lug 11 for easy lifting operations.

[0029] In this embodiment, there are two middle clamps 4, which are symmetrically arranged on both sides of the upper coil pressure member 1. That is, the middle clamps 4 are distributed on both sides of the magnetically controlled reactor body, which can provide lateral support for the iron yoke laminations, so that the iron yoke laminations are subjected to balanced forces on both sides, greatly reducing the risk of deformation of the iron yoke laminations with wavy patterns, thereby improving the assembly quality of the reactor body.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
