A high-precision fully automatic AC voltage regulator

Abstract

This invention provides a high-precision fully automatic AC voltage stabilizer, comprising a cabinet and multiple shelves spaced apart along the height of the cabinet. A transformer is mounted on each shelf, and the transformer coil is fixed with clamps. The bottom of the clamp is fixed to the lower shelf via at least one mounting foot, and its top is fixed to the upper shelf via a connecting plate assembly. This creates a vertically linked support structure between the transformer and the cabinet, significantly lowering the overall center of gravity and improving structural stability and safety during handling and transportation. Furthermore, the connecting plate assembly utilizes the existing clamp structure for fixing the transformer coil, allowing for a shorter connecting assembly, reducing the number of components used and lowering costs.

Description

Technical Field

[0001] This utility model relates to the field of voltage regulator technology, specifically to a high-precision fully automatic AC voltage regulator. Background Technology

[0002] AC voltage stabilizers, as key equipment for ensuring power quality, typically employ a cabinet structure. Multiple transformers are arranged at intervals along the height of the cabinet to achieve voltage regulation and stabilization. However, in existing structures, each transformer is independently fixed inside the cabinet. Due to the significant weight of the transformers and their distribution along the cabinet's height, the overall center of gravity is relatively high. During handling and subsequent transportation, external disturbances such as vehicle bumps and lifting swaying can easily cause vibrations in the cabinet. Prolonged or severe shaking can easily lead to loose or even detached wiring. Loose wiring not only increases contact resistance and causes excessive localized temperature rise, but in severe cases, it can also lead to electrical connection failure, affecting the normal operation and reliability of the AC voltage stabilizer. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a high-precision fully automatic AC voltage regulator with high safety and reliability.

[0004] Therefore, this utility model provides a high-precision fully automatic AC voltage stabilizer, including a cabinet and multiple shelves spaced apart along the height of the cabinet. A transformer is installed on each shelf, and the coil of the transformer is fixed with a clamp. The bottom of the clamp is fixed to the lower shelf by at least one mounting foot, and its top is fixedly connected to the upper shelf by a connecting plate assembly.

[0005] The connecting plate assembly includes a U-shaped first mounting plate, an inverted U-shaped second mounting plate, and at least one vertically arranged connecting plate. The first mounting plate is fixed to the bottom of the layer plate, the second mounting plate is fixed to the top of the clamp and is arranged opposite to the first mounting plate, and the connecting plate is arranged on the side of the first mounting plate and the second mounting plate, and its two ends are respectively fixedly connected to the first mounting plate and the second mounting plate by corresponding bolt assemblies.

[0006] Both the first mounting plate and the second mounting plate are formed with first threaded holes. Both ends of the connecting plate are formed with first elongated holes corresponding to the first threaded holes. After the bolt assembly passes through the first elongated holes and the first threaded holes in sequence, the two ends of the connecting plate are fixed to the first mounting plate and the second mounting plate respectively.

[0007] The connecting plate has reinforcing plates on its left and right sides, which are perpendicular to it.

[0008] The top of the cabinet is provided with a crossbeam that is opposite to the second mounting plate on the top of the adjacent clamp. A second elongated hole is formed on the crossbeam. A second threaded hole is formed on the horizontal plate of the second mounting plate that is opposite to the second elongated hole. The bolt assembly passes through the second elongated hole and the second threaded hole in sequence to fix the crossbeam and the second mounting plate.

[0009] A third mounting plate is vertically provided on the layer, and the transformer includes a voltage regulating transformer and a compensation transformer located on both sides of the third mounting plate.

[0010] The third mounting plate is vertically provided with screws. After the screws pass through the through hole in the middle of the compensation transformer, the compensation transformer is fixed to the third mounting plate by the pressure ring.

[0011] The central axis of the voltage regulating transformer is set perpendicular to the central axis of the compensation transformer.

[0012] The side panel of the cabinet is equipped with a terminal block for connecting to external cables.

[0013] It also includes a waterproof cover installed on the side panel of the cabinet to cover the wiring terminals, with an opening at the bottom for inserting external cables.

[0014] The technical solution of this utility model has the following advantages: 1. The high-precision fully automatic AC voltage stabilizer provided by this utility model has a clamp whose bottom is fixed to the lower shelf by mounting feet, and its top is fixedly connected to the upper shelf by a connecting plate assembly, so that the transformer and the cabinet form an upper and lower linkage support structure, which significantly lowers the overall center of gravity and improves the structural stability and safety reliability during handling and transportation; in addition, the connecting plate assembly utilizes the original clamp structure used to fix the transformer coil, reducing the amount of connecting plate assembly used and reducing costs.

[0015] 2. The high-precision fully automatic AC voltage stabilizer provided by this utility model includes a first mounting plate, a second mounting plate, and a connecting plate in the connecting plate assembly. The two ends of the connecting plate are fixed to the first mounting plate and the second mounting plate respectively by bolt assembly. The installation structure is simple and reliable, and easy to disassemble and maintain.

[0016] 3. The high-precision fully automatic AC voltage stabilizer provided by this utility model has reinforcing plates on both sides of the connecting plate, which effectively improves the rigidity and bending resistance of the connecting plate assembly and further enhances the reliability of the support structure.

[0017] 4. The high-precision fully automatic AC voltage stabilizer provided by this utility model has a crossbeam on the top of the cabinet. The crossbeam and the second mounting plate are fixedly connected by a bolt assembly, so that the top clamp and the top of the cabinet form a rigid connection, which avoids the transformer on the top shaking during transportation.

[0018] 5. The high-precision fully automatic AC voltage stabilizer provided by this utility model has a third mounting plate vertically arranged on the shelf. The transformer includes a voltage regulating transformer and a compensation transformer located on both sides of the third mounting plate. The central axis of the voltage regulating transformer is set perpendicular to the central axis of the compensation transformer. The layout is compact and reasonable, which improves the utilization rate of the internal space of the cabinet.

[0019] 6.

An opening is provided at the bottom of the waterproof cover for the insertion of external cables, which can not only ensure the convenience and reliability of electrical connection, but also effectively prevent rainwater and dust from entering, thus improving the protection level of the product.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Example This embodiment provides a high-precision fully automatic AC voltage regulator, such as... Figure 1 and Figure 2As shown, it includes a cabinet 1 and multiple shelves 2 spaced apart along the height of the cabinet 1. Each shelf 2 is equipped with a transformer 3. The transformer 3 includes a voltage regulating transformer 18 and a compensation transformer 19 located on both sides of the third mounting plate 17, as shown. Figure 3 As shown, the coil 4 of transformer 3 is fixed with a clamp 5, and the bottom of the clamp 5 is fixed to the lower shelf 2 by at least one mounting foot 6.

[0028] In this embodiment, the top of the clamp 5 of the voltage regulating transformer 18 is fixedly connected to the upper layer 2 via the connecting plate assembly 7. For example... Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the connecting plate assembly 7 includes a U-shaped first mounting plate 8, an inverted U-shaped second mounting plate 9, and a vertically arranged connecting plate 10. The first mounting plate 8 is fixed to the bottom of the layer plate 2, and the second mounting plate 9 is fixed to the top of the clamp 5 and is arranged opposite to the first mounting plate 8. The connecting plate 10 is disposed on the side of the first mounting plate 8 and the second mounting plate 9, and its two ends are respectively fixedly connected to the first mounting plate 8 and the second mounting plate 9 by corresponding bolt assemblies. The left and right sides of the connecting plate 10 are provided with reinforcing plates 13 arranged perpendicularly thereto. The first mounting plate 8 and the second mounting plate 9 are both formed with first threaded holes 11, and both ends of the connecting plate 10 are formed with first elongated holes 12 corresponding to the first threaded holes 11. After the bolt assembly passes through the first elongated holes 12 and the first threaded holes 11 in sequence, the two ends of the connecting plate 10 are fixed to the first mounting plate 8 and the second mounting plate 9 respectively.

[0029] As an alternative implementation, the two connecting plates 10 are respectively mounted on the two sides of the first mounting plate 8 and the second mounting plate 9.

[0030] like Figure 3 and Figure 5 As shown, the top of the cabinet 1 is provided with a crossbeam 14 that is opposite to the second mounting plate 9 on the top of the adjacent clamp 5. The crossbeam 14 is formed with a second elongated hole 15. The horizontal plate of the second mounting plate 9 is formed with a second threaded hole 16 that is opposite to the second elongated hole 15. The bolt assembly passes through the second elongated hole 15 and the second threaded hole 16 in sequence to fix the crossbeam 14 to the second mounting plate 9.

[0031] like Figure 6 and Figure 7As shown, a third mounting plate 17 is vertically mounted on the shelf 2, and a screw 20 is vertically mounted on the third mounting plate 17. The screw 20 passes through the central through hole of the compensation transformer 19 and is then fixed to the compensation transformer 19 on the third mounting plate 17 by a pressure ring 21. It should be noted that the size of the voltage regulating transformer 18 is larger than that of the compensation transformer 19, and the central axis of the voltage regulating transformer 18 is perpendicular to the central axis of the compensation transformer 19. This compact and reasonable layout improves the utilization rate of the internal space of the cabinet.

[0032] like Figure 8 and Figure 9 As shown, a terminal block 22 for connecting to an external cable is installed in the middle of the side panel of the cabinet 1, and a waterproof cover 23 is installed on the side panel of the cabinet 1 to cover the terminal block 22. An opening for inserting the external cable is provided below the waterproof cover 23.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
