Description

Technical Field

[0001] The utility model relates to the technical field of power regulators, in particular to a three-phase power regulator. Background Art

[0002] Current three-phase power regulators have a control circuit and a trigger circuit on their mainboard. Since the mainboard and thyristors are fixed in position, the trigger line connecting the thyristors and the trigger pulse on the mainboard is long. This long trigger line not only subjects the device to strong electromagnetic interference, affecting the stability of the device, but also makes wiring more difficult during assembly, resulting in low assembly efficiency. Utility Model Content

[0003] Based on this, it is necessary to provide a three-phase power regulator to address the above problems, which can effectively reduce or eliminate the impact of electromagnetic radiation and further improve the overall stability of the equipment.

[0004] A three-phase power conditioner includes a chassis main body, a control main board, a trigger main board and a thyristor installed in the chassis main body from top to bottom in sequence, a trigger being installed on the trigger main board, a left metal plate and a right metal plate being installed on opposite sides of the chassis main body, a second trigger wire being provided on the left side of the left metal plate, one end of the second trigger wire being connected to the control main board after passing through the left metal plate, and the other end of the second trigger wire being connected to the trigger main board after passing through the left metal plate, a first trigger wire being provided on the right side of the right metal plate, one end of the first trigger wire being connected to the trigger after passing through the right metal plate, and the other end of the first trigger wire being connected to the thyristor after passing through the right metal plate, a central processing unit being installed on the control main board, and a base being installed at the bottom of the chassis main body.

[0005] As a preferred solution, a first box body is installed on the left metal plate for placing the first trigger wire, and a first winding assembly for winding the first trigger wire is installed in the first box body.

[0006] As a preferred solution, a second box body is installed on the right metal plate for placing the second trigger wire, and a second winding assembly for winding the second trigger wire is installed on the second box body.

[0007] As a preferred solution, the first winding assembly and the second winding assembly both include a guide rod, a first sleeve, a second sleeve, a first bracket, a second bracket and a first spring; wherein, the first box body and the second box body are both vertically fixedly connected with a guide rod, the first sleeve and the second sleeve are both sleeved on the guide rod, and the first sleeve and the second sleeve can only slide vertically along the guide rod, the first spring is sleeved on the guide rod between the first sleeve and the second sleeve, the first bracket is connected to the first sleeve, and the second bracket is connected to the second sleeve.

[0008] As a preferred solution, the guide rod is a prism, and the first sleeve and the second sleeve have prismatic through holes that match the prism.

[0009] The utility model is beneficial in that:

[0010] 1. By dividing the traditional main board into a control main board and a trigger main board, and installing the trigger main board between the thyristor and the control main board, this not only shortens the distance between the trigger pulse on the trigger main board and the thyristor, but also optimizes the wiring method, reduces the electromagnetic interference of the trigger line, and makes the line arrangement more reasonable, with obvious optimization effect.

[0011] Second, two winding assemblies are designed. The overlong trigger wire is subsequently wound in an orderly and circular manner on the first bracket and the second bracket. The spring then pushes the first sleeve and the second sleeve to expand outward, thereby preventing the trigger wire wound on the two brackets from becoming loose. BRIEF DESCRIPTION OF THE DRAWINGS

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention.

[0019] like Figure 1 and Figure 2 As shown,

[0020] As an optional embodiment,

[0021] A three-phase power regulator includes a chassis body 1, a control main board 6, a trigger main board 4 and a thyristor 5 installed in sequence from top to bottom inside the chassis main body 1, a trigger 7 is installed on the trigger main board 4, a left metal plate 2 and a right metal plate 3 are installed on opposite sides of the chassis main body 1, a second trigger wire 11 is provided on the left side of the left metal plate 2, one end of the second trigger wire 11 passes through the left metal plate 2 and is connected to the control main board 6, the other end of the second trigger wire 11 passes through the left metal plate 2 and is connected to the trigger main board 4, a first trigger wire 10 is provided on the right side of the right metal plate 3, one end of the first trigger wire 10 passes through the right metal plate 3 and is connected to the trigger 7, the other end of the first trigger wire 10 passes through the right metal plate 3 and is connected to the thyristor 5, a central processing unit 8 is installed on the control main board 6, and a base 9 is installed at the bottom of the chassis main body 1.

[0022] Specifically, in order to prevent the device from being affected by strong electromagnetic interference and affecting the stability of the device, the control main board 6 and the trigger main board 4 are connected through the second trigger line 11, and the second trigger line 11 is isolated by the left metal plate 2 (left side plate); at the same time, the trigger 7 and the thyristor 5 are connected through the first trigger line 10, and the first trigger line 10 is isolated by the right metal plate 3 (right side plate). The two trigger lines are in independent spaces, and the corresponding metal plates can reduce or eliminate the influence of electromagnetic interference and reduce the excessive exposure of the trigger line to a strong magnetic environment.

[0023] In addition, the control main board 6 adopts a thyristor control main board 6, and the main circuit and the control circuit on the main board adopt the same power supply circuit to provide power supply voltage.

[0024] Based on the first embodiment, Figure 2 and Figure 3 shown

[0025] A first box body 13 is mounted on the left metal plate 2 for accommodating the first trigger wire 10 , and a first winding assembly 12 for winding the first trigger wire 10 is mounted in the first box body 13 .

[0026] A second box body 15 is mounted on the right metal plate 3 for accommodating the second trigger wire 11 , and a second winding assembly 14 for winding the second trigger wire 11 is mounted on the second box body 15 .

[0027] To address the problem that the trigger wires used to connect electronic components are long and easily tangled, which makes it difficult to manage the wires during subsequent maintenance and reduces the overall assembly efficiency, two winding assemblies are designed to allow the excessive trigger wires to be wound in an orderly manner without affecting the normal use of the equipment. The specific structures of the two winding assemblies are as follows:

[0028] like Figure 3 It can be seen that the first winding assembly 12 and the second winding assembly 14 both include a guide rod 16, a first sleeve 17, a second sleeve 18, a first bracket 19, a second bracket 20 and a first spring 21; wherein, the first box body 13 and the second box body 15 are both vertically fixedly connected with the guide rod 16, the first sleeve 17 and the second sleeve 18 are both sleeved on the guide rod 16, and the first sleeve 17 and the second sleeve 18 can only slide vertically along the guide rod 16, the first spring 21 is sleeved on the guide rod 16 between the first sleeve 17 and the second sleeve 18, the first bracket 19 is connected to the first sleeve 17, and the second bracket 20 is connected to the second sleeve 18.

[0029] The overlong trigger wire is then wound in an orderly and cyclic manner around the first bracket 19 and the second bracket 20. The spring then pushes the first sleeve 17 and the second sleeve 18 outward to prevent the trigger wire from becoming loose. It is worth noting that in other embodiments, either the first sleeve 17 or the second sleeve 18 can be fixedly connected to the guide rod 16 to constrain the height of the trigger wire winding. To address the aforementioned problem of "the first sleeve 17 and the second sleeve 18 being able to slide only vertically along the guide rod 16" and further constrain the two sleeves from rotating horizontally on the guide rod 16, the following specific improvement is made: the guide rod 16 is selected as a prism, and the first sleeve 17 and the second sleeve 18 have prismatic through holes that cooperate with the prism. This ensures that the first bracket 19 and the second bracket 20 always remain on the same side of the guide rod 16, facilitating subsequent winding.

[0030] The various electronic components mentioned above, such as the trigger motherboard, thyristors, control motherboard, trigger, and central processing unit, are all prior art and no specific improvements have been made to these components. In addition, the above-mentioned embodiments only express several implementation methods of the utility model. The descriptions are relatively specific and detailed, but they should not be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these are all within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the appended claims.
