Technical Field

[0001] The utility model relates to the technical field of three-phase voltage stabilizers, in particular to a three-phase voltage stabilizer with a coil locking function which is applied to power transmission. Background Art

[0002] A three-phase voltage stabilizer is a device used to stabilize three-phase AC voltage. It is mainly composed of a voltage stabilizing transformer and a voltage stabilizing control circuit. Its working principle is based on automatic voltage regulation and stabilization technology. When the input voltage fluctuates, the voltage stabilizing control circuit will adjust the transformation ratio of the voltage stabilizing transformer according to the actual situation to maintain the stability of the output voltage.

[0003] A bracket is usually provided on the three-phase voltage stabilizer, and then the three-phase voltage stabilizer is connected to the bracket by bolts. However, during the use of the three-phase voltage stabilizer, it is easy to collide or be affected by the external weather environment, which may cause appearance damage or line connection problems. Therefore, the bolted connection method requires maintenance personnel to spend more time on disassembly and assembly when it needs to be disassembled for maintenance, and the disassembly and assembly effect may not be standard, which may cause the three-phase transformer to shake after reinstallation. In addition, the bolted fixing method is not convenient for adjusting the position when installing the three-phase voltage stabilizer component, which may complicate the installation process and increase the installation time, and has certain limitations.

[0004] Therefore, we propose a three-phase voltage stabilizer with coil locking function for power transmission to solve the above-mentioned technical problems. Utility Model Content

[0007] As a preferred solution, the side wall of the clamping plate is attached with an anti-skid cushion layer, and the anti-skid cushion layer can be made of, but is not limited to, insulating silicone.

[0008] As a preferred embodiment, the driving mechanism includes a bidirectional threaded rod and a knob, the bidirectional threaded rod is rotatably set in an installation groove, and the I-shaped block is threadedly connected to the bidirectional threaded rod, the knob is rotatably set on one side of the base, and the knob slides and extends to the inner side of the base to be connected to the bidirectional threaded rod.

[0009] As a preferred solution, the adjustment mechanism includes an installation groove 2, a clamping plate 1 and an anti-slip bolt. The installation groove 2 is opened on the base 2. The clamping plate 1 is provided with a plurality of anti-slip bolts located inside the base 2 relative to the clamping plate 2. The anti-slip bolt is provided between the clamping plate 2 and the clamping plate 1.

[0010] As a preferred solution, a plurality of heat dissipation holes are distributed on the outer wall of the box body.

[0011] As a preferred solution, insulating silicone is attached to a side of the second clamping piece close to the compensation coil.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly has the following advantages:

When the nut part of the anti-slip bolt is loosened, the whole formed by the clamping piece one, the clamping piece two and the anti-slip bolt can cooperate with the installation groove two to move the adjustment position on the base two. When the nut part of the anti-slip bolt is tightened, the whole formed by the clamping piece one, the clamping piece two and the anti-slip bolt can cooperate with the installation groove two to move the adjustment position on the base two. The above method can facilitate the operator to complete the locking process of the voltage regulating coil and the compensation coil.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] See also Figures 1 to 7The embodiment of the utility model provides a three-phase voltage stabilizer with a coil locking function for power transmission, comprising a box body 1, a plurality of support seats 2 distributed at the lower end of the box body 1, and a box door 3 arranged at the front end of the box body 1. The support seats 2 are specifically provided with four, which are fixed to the lower end of the box body 1 by welding. The support seats 2 are used to support and increase the overall height of the box body 1 to reduce the influence of the humid ground on the box body 1. A bracket 5 is arranged in the box body 1, and the bracket 5 is fixed in the box body 1 by welding, and is located in the middle of the upper and lower parts. The internal space of the box body 1 is divided into two spaces, one above and one below, and a base 6 is fixed on the bracket 5. The base 6 is fixedly connected to the bracket 5 by bolts. A voltage regulating coil 7 is arranged on the base 6, and the voltage regulating coil 7 is directly placed on the base 6. At the same time, a positioning bolt is arranged on the base 6. When the voltage regulating coil 7 is slid and pushed on the base 6, when the base part of the voltage regulating coil 7 contacts the positioning bolt, it is the standard position. In this way, the standard installation position of the voltage regulating coil 7 can be confirmed, so that it is convenient for the installer to locate the installation position of the voltage regulating coil 7. A mounting groove 9 is opened in the base 6, and a plurality of I-shaped blocks 10 are arranged on the outside of the voltage regulating coil 7 in a mirror image, and the I-shaped blocks 10 are slidably connected with the base 6 through the mounting groove 9. There are two I-shaped blocks 10, which are distributed on the left and right sides of the voltage regulating coil 7. On the side, one end of the I-shaped block 10 close to the voltage regulating coil 7 is connected with a clamping plate 18, and the side wall of the clamping plate 18 is attached with an anti-skid cushion layer, and the anti-skid cushion layer can be made of but not limited to insulating silicone. The insulating silicone can reduce the electric shock during adjustment, and at the same time, it can reduce the loss of the outer wall of the voltage regulating coil 7 caused by the clamping plate 18 during installation. A base 17 is fixed to the bottom of the inner side of the box body 1, and a compensation coil 8 is installed on the base 17. A plurality of clamping pieces 15 are arranged on both sides of the compensation coil 8. The clamping pieces 15 are arranged in two groups, which are distributed on the left and right sides of the compensation coil 8. The side of the clamping piece 15 close to the compensation coil 8 is attached with insulating silicone. The insulating silica gel can reduce the electric shock during adjustment, and at the same time can reduce the loss caused by the clamping piece 15 to the outer wall of the compensation coil 8 during installation. The outer wall of the box body 1 is provided with a plurality of heat dissipation holes 4, through which the internal space of the box body 1 can be connected with the external environment, so as to dissipate heat. When the device is used, by moving the two groups of I-shaped blocks 10 to slide on the base 1 6, the clamping plate 18 can be driven to move to complete the limit locking of the lower end of the voltage regulating coil 7, thereby completing the locking process. When the voltage regulating coil 7 needs to be disassembled and assembled, the disassembly can be completed by moving the I-shaped block 10 in the opposite direction, which is convenient for disassembly and assembly.

[0026] See also Figures 1 to 7The base 6 is provided with a driving mechanism for adjusting the spacing between multiple I-shaped blocks 10. The driving mechanism includes a bidirectional threaded rod 11 and a knob 12. The bidirectional threaded rod 11 is rotatably arranged in the installation groove 9, and the I-shaped block 10 is screwed with the bidirectional threaded rod 11. The knob 12 is rotatably arranged on one side of the base 6, and the knob 12 slides and extends to the inner side of the base 6 and is connected with the bidirectional threaded rod 11. When the device is used, the bidirectional threaded rod 11 can be driven to rotate by rotating the knob 12 clockwise or counterclockwise, so that the I-shaped block 10 that is in sliding contact with the base 6 and screwed with the bidirectional threaded rod 11 moves away from or close to the voltage regulating coil 7 as the knob 12 rotates clockwise or counterclockwise. The position of the clamping plate 18 can be adjusted by moving the I-shaped block 10 to complete the limited clamping of the voltage regulating coil 7, thereby facilitating disassembly and assembly. Moreover, since the I-shaped block 10 can be adjusted and moved, the clampable voltage regulating coil 7 has high adaptability and is more practical.

[0027] See also Figures 1 to 7 An adjusting mechanism for adjusting the spacing of multiple anti-slip bolts 16 is provided in the base 17, and the adjusting mechanism includes a mounting groove 13, a clamping piece 14 and an anti-slip bolt 16. The mounting groove 13 is opened on the base 17, and the clamping piece 14 is provided with multiple anti-slip bolts 16 located in the base 17 relative to the clamping piece 15. The anti-slip bolt 16 is penetrated and arranged between the clamping piece 15 and the clamping piece 14. The lower end of the anti-slip bolt 16 passes through the clamping piece 14 and is arranged in the mounting groove 13. When the nut part of the anti-slip bolt 16 is loosened, the whole formed by the clamping piece 14, the clamping piece 15 and the anti-slip bolt 16 can cooperate with the mounting groove 13 to move the adjustment position on the base 17. When the nut part of the anti-slip bolt 16 is tightened, the whole formed by the clamping piece 14, the clamping piece 15 and the anti-slip bolt 16 can cooperate with the mounting groove 13 to move the adjustment position on the base 17.

[0028] In summary, the device can cooperate with the base 16 through the driving mechanism composed of the bidirectional threaded rod 11 and the knob 12 to make the I-shaped block 10 move away from or close to the voltage regulating coil 7, thereby driving the clamping plate 18 to move, thereby completing the limited clamping or releasing the clamping of the voltage regulating coil 7. When the nut part of the anti-slip bolt 16 is loosened, the whole formed by the clamping piece 14, the clamping piece 2 15 and the anti-slip bolt 16 can cooperate with the installation groove 2 13 to move the adjustment position on the base 2 17. When the nut part of the anti-slip bolt 16 is tightened, the whole formed by the clamping piece 14, the clamping piece 2 15 and the anti-slip bolt 16 can cooperate with the installation groove 2 13 to move the adjustment position on the base 2 17. The above method can be used to facilitate the operator to complete the locking process of the voltage regulating coil 7 and the compensation coil 8.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
