Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor technology, specifically a novel reactor mounting structure. Background Technology
[0002] Reactors, as key reactive power compensation and current limiting devices in power systems, are widely used in power distribution, industrial frequency conversion, and new energy fields. In existing technologies, high-power reactors are typically fixed to a concrete foundation or mounting platform using anchor bolts through multiple mounting holes on their base. This bolted connection method is fundamental to ensuring the reactor's structural stability under the combined effects of electromagnetic forces, its own weight, and external vibrations. However, the nuts may loosen due to continuous, high-frequency micro-mechanical vibrations or vibrations from other surrounding electrical equipment. Once the connection loosens, it not only generates abnormal noise but can also cause reactor displacement, leading to increased stress at electrical connection points, insulation damage, or even equipment failure—serious safety accidents. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model provides a novel reactor mounting structure.
[0004] The technical solution of this utility model is as follows: A novel reactor mounting structure includes two segmented mounting frames that can form a rectangular frame and are detachably connected by a first connector. The reactor includes a base with multiple first mounting holes, which is set on a base located on the ground. The first mounting holes are connected to the anchor bolts on the base. Each segmented mounting frame is provided with a second mounting hole corresponding to the anchor bolt. The segmented mounting frame is erected on the base and connected to the base through a second connector located thereon.
[0005] The two segmented mounting frames can be combined into a rectangular structure. Specifically, the segmented mounting frames are L-shaped or ⨆-shaped, and the combined rectangular structure is easy to install on the reactor base.
[0006] The connection structure of the two segmented mounting frames is as follows: one segmented mounting frame has insertion slots at both ends, and the other segmented mounting frame has insertion blocks at both ends that are adapted to the insertion slots. The first connector passes through the insertion blocks and insertion slots to connect the two segmented mounting frames.
[0007] Furthermore, each end of the segmented mounting frame has two first elongated holes communicating with the insertion slot, at least one of which is a threaded hole. The insertion block has a second elongated hole corresponding to the first elongated hole. The first connector is threadedly connected to the segmented mounting frame. The first connector is a fastening bolt, which passes through the first elongated hole and the second elongated hole and is threadedly connected to the first elongated hole, used to connect the two segmented mounting frames. The second elongated hole can also be a threaded hole to improve the stability of the fastening bolt connection.
[0008] Preferably, the reactor includes a reactor body mounted on a base, the reactor body being connected to the base via a lower bracket, and a baffle assembly adapted to the segmented mounting frame being provided on the side near the lower bracket.
[0009] The baffle assembly consists of two symmetrically arranged baffles. The vertical distance between the two baffles is adapted to the thickness of the lower support. The lower support is plugged into the baffle assembly in a vertical direction. The two baffles of the baffle assembly can be directly snapped into the side of the lower support during installation, which is convenient for installation and positioning, facilitates the installation of the baffle, and avoids displacement of the segmented frame.
[0010] Furthermore, the width of the segmented mounting frame near the second connector is greater than the maximum length of the second connector, which upgrades the segmented mounting frame from a passive load-bearing component to an active rigid load-bearing platform. The increased width not only provides a larger lever arm to enhance the stability of the equipment against overturning moments, but also optimizes the concentrated load of the bolts into a more uniform distributed load, effectively preventing the equipment base from warping and deforming.
[0011] The beneficial effects of this utility model are as follows: Existing technology connects the base to the anchor bolts of the foundation using only nuts. However, each bolt and nut pair bears the load independently, forming a discrete "point contact" clamping method. This results in uneven force on the equipment base, which is prone to stress concentration and cannot effectively form a cohesive load-bearing system. This utility model integrates multiple independent anchor bolt fastening points into a unified system that coheses the load by using a rectangular frame. This optimizes the load distribution from "point contact" to "surface distribution", thereby evenly dispersing the clamping force and avoiding stress concentration. Furthermore, by utilizing the mechanical interlocking effect formed between the bolts by the rigid rectangular frame, the loosening tendency of any bolt is effectively constrained by the adjacent fastening points; at the same time, the preload integrated by the system generates a huge static friction force between the rectangular frame and the equipment base, which can reduce the loosening of bolts and the displacement of the base.

[0013] See Figure 1 , Figure 2 and Figure 3 As shown, a novel reactor mounting structure includes two segmented mounting frames 5, which can form a rectangular frame, and the two segmented mounting frames 5 are detachably connected by a first connector 6.
[0014] The reactor includes a reactor body 3 and a base 4 supporting it. The reactor body 3 is connected to the base 4 via a lower bracket 31. The base 4 has multiple first mounting holes, which are existing technology and are not shown in the figure. The base 4 is set on a base 1 located on the ground. The base 1 has four anchor bolts 2. The first mounting holes are connected to the anchor bolts 2 on the base 1. Each segmented mounting frame 5 has a second mounting hole 51 corresponding to the anchor bolt 2. The segmented mounting frame 5 is erected on the base 4 and connected to the base 4 via a second connector 7 located on it. The second connector 7 is a nut adapted to the anchor bolt 2, and a washer or elastic washer is provided under the nut. By integrating multiple independent anchor bolt 2 fastening points into a unified system of coordinated force distribution through the rectangular frame, the load is optimized from "point contact" to "surface distribution", thereby evenly distributing the clamping force and avoiding stress concentration.
[0015] The two segmented mounting frames 5 can be combined to form a rectangular structure. Specifically, in this embodiment, the segmented mounting frames 5 are of a U-shape, and the resulting rectangular structure facilitates installation on the reactor base 4. In this embodiment, one segmented mounting frame 5 has insertion slots 8 at both ends, and the other segmented mounting frame 5 has insertion blocks 9 at both ends that are compatible with the insertion slots 8. The first connector 6 passes through the insertion blocks 9 and the insertion slots 8 to connect the two segmented mounting frames 5.
[0016] Each end of the segmented mounting frame 5 has two first elongated holes 52 communicating with the insertion slot 8. At least one of the first elongated holes 52 is a threaded hole. The insertion block 9 has a second elongated hole 91 corresponding to the first elongated hole 52. The first connecting member 6 is threadedly connected to the segmented mounting frame 5. The first connecting member 6 is a fastening bolt that passes through the first elongated hole 52 and the second elongated hole 91 and is threadedly connected to the first elongated hole 52. It is used to connect the two segmented mounting frames 5. The second elongated hole 91 can also be a threaded hole to improve the stability of the fastening bolt connection.
[0017] The segmented mounting frame 5 has a matching baffle 10 assembly on the side near the lower support 31. The baffle 10 assembly consists of two symmetrically arranged baffles 10, the vertical distance between the two baffles 10 being adapted to the thickness of the lower support 31. The lower support 31 is plugged into the baffle 10 assembly in a vertical direction. The two baffles 10 of the baffle 10 assembly can be directly engaged with the side of the lower support 31 during installation, which is convenient for installation and positioning, facilitates the installation of the baffle 10, and prevents displacement of the segmented frame.
[0018] The width of the segmented mounting frame 5 near the second connector 7 is greater than the maximum length of the second connector 7, which upgrades the segmented mounting frame 5 from a passive load-bearing component to an active rigid load-bearing platform. The increased width not only provides a larger lever arm to enhance the stability of the equipment against overturning moments, but also optimizes the concentrated load of the bolts into a more uniform distributed load, effectively preventing the equipment base 4 from warping and deforming.
